  The conventional skin treatment device has a configuration shown in the above-mentioned patent document. In such a device, the treatment effect can be enhanced as the irradiation intensity of light is increased. Obstacles to eyes when viewed directly are enormous. Among these devices, those for home use and personal use have a mechanism that can sufficiently irradiate the skin with light, but in order to have a simple configuration, there is often nothing to block the emitted light around. If the device being used is moved away from the skin more than necessary, or if the direction of light irradiation is not correctly directed to the skin treatment area, the light irradiated at a predetermined intensity suitable for treatment will be mistaken. The incident on the eyes of the user can also occur. In this case, there is a problem that the risk of seriously affecting the eyes is extremely high.

  In particular, in the case of equipment that irradiates ultraviolet rays or infrared rays, it is difficult to grasp the intensity of such light other than visible light, and it is difficult to grasp its intensity. There was a problem that could be.

  In addition to the effects on the eyes, the light irradiation in the state where the light in the conventional device is not directed to the skin is an unnecessary irradiation operation, and it consumes power unnecessarily. It was.

  The present invention has been made to solve the above-mentioned problems, and automatically detects a situation in which light irradiated for treatment may enter the eye by mistake, and adjusts the light intensity so that the light is in the eye. The purpose is to provide a treatment device that can be safely used with reduced risk of entering.

The treatment device according to the present invention is a treatment device that irradiates the skin of a user with light of a predetermined wavelength to produce a predetermined treatment effect, covers the periphery of the irradiation unit that irradiates light, and is disposed on the front side of the irradiation unit. A substantially cylindrical guide part closed except for the opening part, and suction means for sucking air in the guide part through a suction hole provided at a predetermined position facing the guide part, the guide part being disposed in front of the irradiation part Compared to the part close to the main body part except for the opening part on the side, it is a tapered substantially cylindrical body with a small diameter on the opening side that comes into contact with the skin, from the part close to the main body part so as to improve the adhesion to the skin It is formed of a flexible elastic material whose thickness is reduced as it approaches the peripheral edge of the opening, and the suction peripheral of the guide part is deformed inward by suction of the suction means so that the suction force is applied to the skin guide part. The distance between the skin and the irradiated area is maintained. In correspondence with the contracted state, it is intended to increase the illumination intensity of light.
As described above, according to the present invention, the attraction of the skin into the guide portion by the suction force is improved, the distance between the skin and the irradiation portion can be further shortened, and the light irradiation intensity is increased corresponding to the contracted state. The safety is further improved by this, and the treatment effect on the skin by light is excellent.
Further, a treatment device that is a reference of the present invention is a treatment device that irradiates the skin of a user with light of a predetermined wavelength to produce a predetermined treatment effect, and covers the periphery of an irradiation unit that irradiates light, A substantially cylindrical guide part that is closed except for the opening part on the front side of the part, a suction means for sucking air in the guide part through a suction hole provided in a predetermined position facing the guide part, and suction by the suction means A detection unit for detecting a predetermined physical quantity change between a state in which skin is in contact with and / or approaching the peripheral edge of the opening in the guide unit and a state in which skin is not approaching the peripheral edge; A control unit that adjusts the intensity of light emitted from the irradiation unit according to the detection state of the detection unit, and the control unit emits light when the skin is not approaching the peripheral edge. Harmful even if the light is incident on at least human eyes While the skin is in contact with and / or approaching the peripheral edge, the irradiation intensity of the light irradiated from the irradiation unit is set to be a predetermined first irradiation intensity that does not affect the first irradiation intensity. It's something that gets bigger.

As described above, according to the treatment device that is a reference of the present invention, the guide unit and the suction unit that surround the irradiation unit that irradiates light are provided, and the light is directly applied to the human eye while performing the irradiation and suction of the light. In the case where the detection unit detects a physical quantity corresponding to a situation where there is a risk of being incident on the peripheral portion of the opening in the guide unit, that is, a state in which the skin is not approaching the peripheral part of the opening, The first irradiation intensity that does not have a harmful effect even if this light is directly incident on the eye, and conversely, the light from the irradiation part does not reach other than the skin, and the skin contacts and / or approaches the peripheral part. In the case where the detection unit detects a physical quantity corresponding to the current state, the control unit executes control to make the irradiation intensity of light larger than the first irradiation intensity, and is irradiated from the irradiation unit The light passes through the guide opening and the eyes of the patient and the surrounding people While avoiding the danger of being able to enter by mistake, the entire circumference of the opening peripheral edge of the guide part touches or moderately approaches the skin of the user and the light does not reach other than the skin. Sufficient treatment performance will be secured as intense light, and treatment can be performed efficiently while always maintaining safety. In addition, the suction means sucks when irradiating light and sucks the skin to the guide opening, so that the degree of contact between the skin and the opening peripheral edge of the guide is increased, and the light emitted through the opening is directed to other than the skin. In addition to being able to easily and reliably maintain a safe state that does not need to be strongly pressed against the skin, the user's burden can be reduced, and in addition, a part of the skin enters the inside of the guide portion by suction force It is easy, the distance between the skin that has entered the inside of the guide portion and the irradiation portion approaches, the arrival of irradiated light to the skin is promoted, and the treatment effect on the skin by light is further enhanced. Furthermore, even if the guide part is separated from the skin, weak light that does not adversely affect the eyes is emitted. Therefore, when the irradiated light is visible light, the user is informed that the treatment device is in an operating state. Is easy to discriminate, and erroneous operation can be prevented.

In addition, the treatment device that is a reference of the present invention, if necessary, the suction different when the detection unit separates the peripheral part of the opening in the guide part from the skin and when the skin contacts the peripheral part The change of the physical quantity related to the suction load of the means is detected.

As described above, according to the treatment device that is a reference of the present invention, the suction means performs suction simultaneously with the irradiation of light, while the peripheral edge of the opening of the guide portion is not in contact with the skin and when it is in contact with the skin. By utilizing the fact that the suction load is in a different state, the detection unit detects a change in a predetermined physical quantity related to the suction load, and the control unit adjusts the light intensity based on the detection result. Determining the safe state where the light coming out of the opening that touches the skin around the skin does not reach any part other than the skin and the state where the peripheral edge is separated from the skin and enters the eyes of the light coming out of the opening is certain The irradiation intensity of light can be appropriately adjusted and restricted according to whether the entire periphery of the opening edge of the guide portion is in contact with the skin, and the safety during treatment of irradiating light can be reliably maintained. . Further, it is not necessary to provide a sensor or the like for directly detecting the positional relationship between the guide portion and the skin in the vicinity of the guide portion, so that the structure can be simplified and the cost can be reduced.

Moreover, the treatment device used as a reference of the present invention is a guide different depending on the case where the detection unit separates the peripheral part of the opening in the guide part from the skin and the case where the skin contacts the peripheral part. It detects a change in pressure inside the unit.

Thus, according to the treatment device that is a reference of the present invention, when the suction means performs suction, the pressure in the guide portion is different depending on whether the peripheral edge of the guide portion is not in contact with the skin or not. While the suction means performs suction, the pressure sensor as the detection unit detects a pressure change in the guide unit, and the control unit adjusts the light intensity based on the detection result, so that the guide unit A state where the entire periphery of the opening abuts against the skin and the light exiting the opening does not reach other than the skin, and there is a risk that the periphery is separated from the skin and enters the eyes of the light exiting the opening Can be correctly determined and appropriate irradiation intensity adjustment can be performed, and the safety during treatment of irradiating light can be reliably maintained.

Further, in the treatment device to be used as a reference of the present invention, if necessary, the detection unit includes a plurality of pairs of electrodes disposed on the peripheral part of the opening in the guide part, and the peripheral part of the guide part is all skin. The change in the physical quantity related to the energization state between the paired electrodes, which is different between the case where it is not in contact with the case and the case where it is in contact with it, is detected.

As described above, according to the treatment device which is a reference of the present invention, a plurality of pairs of electrodes are arranged on the opening peripheral edge of the guide part, and the case where the guide opening peripheral edge is not in contact with the skin and The change in the current-carrying state between the pair of electrodes in FIG. 5 is used to detect a change in a predetermined physical quantity related to the current-carrying state between the electrodes during light irradiation. By adjusting the irradiation intensity, the entire periphery of the opening edge of the guide part is in contact with the skin and the light that exits the opening does not reach other than the skin, and the edge part leaves the skin and leaves the opening. It is possible to reliably discriminate from the state where there is a risk of light entering the eye, and appropriately adjust and limit the light irradiation intensity according to the presence or absence of contact between the entire periphery of the opening edge of the guide and the skin. In addition to being able to detect light in the detection part, it does not depend on suction, and even if suction is stopped by mistake, Will be able to adjust the intensity, it is to improve the safety and reliability in treatment of irradiating light.

Further, in the treatment device that is a reference of the present invention, the detection unit detects a change in the distance from a predetermined object including the skin of the user who approaches the peripheral edge of the opening in the guide unit, as necessary. A distance measuring sensor is provided.

As described above, according to the treatment device that is a reference of the present invention , the distance measuring sensor capable of detecting the distance to the skin is disposed as the detection unit, and the opening peripheral edge of the guide unit is closer to the case where the distance is away from the skin. Using the fact that the distance between the skin and the sensor differs depending on the case, the distance sensor detects a change in distance while irradiating light, and the control unit adjusts the light irradiation intensity based on the detection result. By doing so, the opening edge of the guide part comes into contact with and / or approaches the skin so that the light that has left the opening does not reach other than the skin, and the eye of the light that has left the skin away from the skin and has left the opening. Appropriate irradiation intensity adjustment can be performed by correctly discriminating the state where there is a risk of entering. In addition, since the detection by the distance measuring sensor as the detection unit does not depend on the suction state and does not require contact between the peripheral edge portion and the skin, the irradiation intensity of light can be adjusted even when the suction is stopped by mistake. In the situation where the light does not reach other than the skin even if the peripheral part is not completely in contact with the skin, the light irradiation intensity is adjusted appropriately and the efficiency is improved. The treatment can be performed well.

(First embodiment of the present invention)
Hereinafter, a treatment device according to a first embodiment of the present invention will be described with reference to FIGS.
In each of the drawings, a treatment device 1 according to the present embodiment is held by a user and directed to a treatment site, and a treatment unit 10 that performs a treatment operation by a built-in irradiation unit 12, an air tube 74, and a cable 75. It is the structure provided with the stand part 15 which is connected with the treatment part 10 and incorporates the pump 50 and the power supply part 60 as a suction means.

  The treatment unit 10 includes a main body 11 that is held by a user's hand, an irradiation unit 12 that is attached to the main body 11 and emits light of a predetermined wavelength, and a periphery of the irradiation unit 12 that emits light. It is a structure provided with the substantially cylindrical guide part 13 which closed, ensuring airtight except for the opening part which covers and contact | abuts skin.

  The body portion 11 is formed in a shape in which the longitudinal direction of the grip portion 11a held by a hand and the front direction of the treatment surface portion 11b provided with the irradiation portion 12 are substantially perpendicular to each other, and the guide portion 13 is provided around the treatment surface portion 11b. It is the structure which can be attached. The treatment surface portion 11 b faces the inside of the guide portion 13, the irradiation portion 12 is disposed, and a suction hole 11 c that sucks air in the guide portion 13 is formed. The grip 11a is provided with an operation switch 11d for switching the treatment operation ON and OFF.

  The irradiation unit 12 includes a high-luminance light emitting diode (LED) that emits light such as infrared light, visible light, and ultraviolet light that causes a predetermined treatment effect on the skin, that is, the body surface layer portion from the epidermis to the subcutaneous tissue. A plurality of known light sources are arranged, and detailed description thereof is omitted. The irradiation unit 12 is not limited to a configuration in which only LEDs that emit any one kind of light, such as infrared light and visible light, are arranged, for example, those that emit infrared light and those that emit visible light are arranged side by side. Also, a configuration in which a plurality of light sources that emit different types of light are arranged in combination may be employed.

  The guide part 13 is formed of an elastic material such as rubber having flexibility, and is a tapered substantially cylindrical body having a small diameter on the opening side to be brought into contact with the skin as compared with a part closer to the main body part 11. It is the structure attached to the part 11 so that attachment or detachment is possible. The guide portion 13 is formed so as to be thinned toward the opening peripheral portion 13a from the portion close to the main body portion 11 so as to enhance the adhesion to the skin, and has a structure with excellent flexibility. Is sucked into the guide portion 13, the peripheral edge portion 13 a is deformed inward and does not excessively compress the skin, but the state of close contact with the skin is properly maintained and the skin is guided into the guide portion by the suction force. This is a mechanism for efficiently holding the drawing state (see FIG. 6). About the guide part 13, when using a light source with a wide light irradiation range as the irradiation part 12, in order to prevent the unexpected leakage of light from other than the opening of the guide part, it is made of a light-shielding material and is continuous without holes or seams. It is preferable to use a configuration made of a cylindrical body.

  The stand unit 15 is integrated with a driving motor 51 to supply power to the pump 50 as the suction unit that sucks air in the guide unit 13 from the suction hole 11c, and to the pump 50 and the irradiation unit 12. The said detection part which detects the change of the pump drive current which concerns on the suction | inhalation load of the pump 50 which is different when the skin leaves | separates with respect to the power supply part 60 and the opening peripheral part 13a of the guide part 13, and the skin contacts. Current detection resistor 14 as a control unit, a control circuit 16 as the control unit that adjusts the intensity of light emitted from the irradiation unit 12 according to the detection state of the current detection resistor 14, and each of those other than the treatment unit 10 It is the structure provided with the housing | casing 70 which accommodates a mechanism.

  The pump 50 communicates with the suction hole 11 c through the air tube 74, performs suction in parallel with the light irradiation by the irradiation unit 12, and removes the skin of the user who is positioned at the opening of the guide unit 13 to the periphery of the opening. The part surrounded by the peripheral part 13a of the skin is brought into close contact with the part 13a and is drawn into the guide part 13. At the time of suction with the pump 50, the guide portion 13 has flexibility, so that the guide portion 13 is also deformed so as to promote entry into the guide portion 13 through the opening of the skin by the suction force, and the skin is applied to the irradiation portion 12. It will approach. In the state where the skin is brought into close contact with the peripheral edge portion 13a by the suction of the pump 50 and is drawn into the guide portion 13, a treatment effect such as removal of square plugs and dirt associated with the suction is given to the skin.

  The current detection resistor 14 is disposed in a circuit through which a pump drive current that increases or decreases corresponding to the suction load in the pump 50, converts a change in the pump drive current into a change in potential, and from this potential change, Changes in the suction load of the pump 50 due to the presence or absence of contact with the opening peripheral portion 13a of the guide portion 13, that is, the state where the skin contacts the peripheral portion 13a of the opening in the guide portion 13 and the suction load is high, and the peripheral portion It is possible to determine whether 13a does not contact the skin and the suction load is low.

  The control circuit 16 operates based on a change in potential detected by the current detection resistor 14 in response to a change in the suction load of the pump 50, and the periphery of the opening in the guide portion 13 while suction is performed. When the entire circumference of the portion 13a comes into contact with the skin, the suction load of the pump 50 increases because the outside air is less likely to enter the guide portion 13 whose opening is completely blocked by the skin, and the potential of the current detection resistor 14 However, with this value as a threshold, the voltage applied to the irradiation unit 12 is increased to increase the irradiation intensity.

  On the contrary, in the state where the peripheral edge portion 13a of the opening in the guide portion 13 is not in contact with the skin, the inflow of air into the guide portion 13 can occur, so that the suction load of the pump 50 is small, and the potential of the current detection resistor 14 Is smaller than the threshold value, and the control circuit 16 suppresses the light irradiation intensity to the first irradiation intensity that does not have a harmful effect even if light enters the human eye.

  Specifically, the control circuit 16 includes a control transistor 17 that is turned on when the potential of the current detection resistor 14 is equal to or higher than the threshold value, and increases the voltage applied to the irradiation unit 12. The voltage limiting resistor 18 is provided to suppress the voltage applied to the irradiation unit 12 when the potential is smaller than the threshold value and the control transistor 17 is in the OFF state.

  When the potential of the current detection resistor 14 is equal to or greater than the threshold value, the skin contacts the entire periphery 13a of the opening in the guide portion 13 to close the opening, and the inside of the guide portion is completely sealed. The current detection resistor 14 is in a state where the skin is in contact with the peripheral portion 13a and the inside of the guide portion is completely sealed, and the light exiting the opening does not reach other than the skin. It can be said that it is detected. In this case, in the control circuit 16, the control transistor 17 is turned on, and the control transistor 17 generates a bypass circuit parallel to the voltage limiting resistor 18 to reduce the electrical resistance in the circuit that operates the irradiation unit 12. The treatment effect is enhanced by increasing the voltage applied to the irradiation unit 12 and increasing the intensity of light irradiated from the irradiation unit 12.

  On the other hand, when the potential of the current detection resistor 14 is lower than the threshold value, the skin is not in contact with the peripheral edge portion 13a of the opening in the guide portion 13, and the light exiting the opening of the guide portion 13 may reach other than the skin. It corresponds to the situation, and it can be said that the current detection resistor 14 detects a state where the peripheral edge portion 13a is not in contact with the skin and the light is likely to reach the eyes, except for the skin.

  In this case, in the control circuit 16, since the potential of the current detection resistor 14 is small and does not reach the threshold value, the control transistor 17 is maintained in the OFF state, and only the voltage limiting resistor 18 is in series with the irradiation unit 12. The voltage applied to the irradiating unit 12 is kept small, and the irradiation intensity of the irradiating unit 12 is maintained at a safe low level even if light enters the eyes.

  The casing 70 is provided with an operation unit 71 such as a main power switch and a suction force adjustment unit, and stores the guide unit 13 that can be attached to and detached from the main body unit 11 and spare parts thereof, and the treatment unit 10. It is the structure by which each recessed part 72 and 73 to accommodate is formed in the surface.

  Next, the operation state in the treatment device according to the present embodiment will be described. As a premise, the treatment device 1 is activated when the power is turned on, and the user (the user himself / herself or another person) has the treatment unit 10 and is directed to the treatment area of the skin, and the user instructs the operation. If “” is input, it is assumed that the treatment operation can be started.

  When the user turns on the operation switch 11d, suction by the pump 50 is started, and at the same time, irradiation of light in the irradiation unit 12 is also started. In the initial state, the light irradiation intensity is low and safe even if it enters the eyes. In the state where the opening peripheral edge portion 13a of the guide portion 13 is separated from the skin, air can flow into the guide portion 13, so that the suction load of the pump 50 is small and the drive current of the pump 50 is not increased. The potential of the current detection resistor 14 is smaller than the threshold value.

  When the peripheral edge 13a of the opening is brought into contact with the skin, the skin is attracted to the opening by the suction of the pump 50 and comes into close contact with the peripheral edge 13a. The skin also closes the opening and completely seals the inside of the guide 13. Since it becomes difficult for external air to flow into the guide portion 13, the suction load of the pump 50 increases, and the drive current of the pump 50 gradually increases accordingly. The drive current of the pump 50 also flows through the current detection resistor 14 of the control circuit 16, but when the current flowing through the current detection resistor 14 increases and the potential of the current detection resistor 14 exceeds the threshold value, the control transistor 17 is turned on. A state in which the voltage applied to the irradiation unit 12 is suppressed by the voltage limiting resistor 18 arranged in parallel between the collector and the emitter of the control transistor 17 is short-circuited by the control transistor 17. As a result, the voltage that is suppressed by the voltage limiting resistor 18 is applied to the irradiation unit 12, and the light irradiation intensity increases to a state suitable for treatment.

  At the same time, a part of the skin enters the guide portion 13 while deforming the guide portion 13 by suction, and the degree of adhesion between the skin and the opening peripheral edge portion 13a of the guide portion 13 increases, and the skin and the guide portion It is possible to easily maintain a safe state in which the light emitted from the opening does not reach other than the skin without leaving the peripheral edge portion 13a of the opening 13 and there is no need to strongly press the guide portion 13 against the skin for complete sealing in the guide portion. In addition to reducing the burden on the user, the distance between the skin that has entered the guide unit 13 and the irradiation unit 12 is also reduced, so that the skin can receive a lot of light from the irradiation unit 12, and the treatment effect on the skin by light Can also be enhanced. At this time, the pores are also expanded by suction on the surface of the skin that has entered the guide portion 13, and light can be irradiated to the skin details such as the pores.

  If the peripheral edge portion 13a of the guide portion 13 is separated from the skin in order to interrupt the treatment or change the treatment position, the air can flow into the guide portion 13 and the suction load of the pump 50 is reduced. The drive current of 50 is also reduced. For this reason, the current flowing through the current detection resistor 14 of the control circuit 16 also decreases, and when the potential of the current detection resistor 14 falls below the threshold value, the control transistor 17 is turned off, and the voltage applied to the irradiation unit 12 is changed to the voltage limiting resistor. 18 shifts to a state of being suppressed. Thus, as the voltage applied to the irradiation unit 12 is suppressed by the voltage limiting resistor 18, the light irradiation intensity is lowered to a safe state without affecting the eyes. In this case, even if the light exiting the opening of the guide portion 13 directly enters the eyes, there is no adverse effect on the eyes. When the treatment is completed, when the user turns the operation switch 11d to the OFF state, the suction by the pump 50 and the light irradiation in the irradiation unit 12 are stopped.

  As described above, the treatment device according to the present embodiment includes the irradiation unit 12 that irradiates light, the guide unit 13 that surrounds the irradiation unit 12, and the pump 50 as the suction unit. When the current detection resistor 14 detects a potential as a physical quantity corresponding to a situation where there is a risk of direct incidence on the human eye, that is, a state where the skin is not approaching the peripheral edge portion 13a of the opening in the guide portion 13. For example, the control circuit 16 sets the irradiation intensity so as not to have a harmful effect even if the light is directly incident on the human eye, and conversely, the light passing through the opening of the guide unit 13 from the irradiation unit 12 reaches other than the skin. When the potential corresponding to the state in which the skin is in contact with the entire periphery of the peripheral portion 13a and the inside of the guide portion 13 is completely sealed is detected by the current detection resistor 14, the control circuit 16 applies the light irradiation intensity. To execute control to increase In addition, it is possible to avoid the danger that the irradiated light may accidentally enter the eyes of the person to be treated and the surrounding people through the opening of the guide portion 13, while the light that has exited the opening of the guide portion 13 does not reach other than the skin In this case, sufficient treatment performance is ensured as light of appropriate intensity, and treatment can be performed efficiently while always maintaining safety. In addition, even if the guide unit 13 is separated from the skin, weak light that does not adversely affect the eyes is irradiated. Therefore, when the irradiated light is visible light, the treatment device is in an operating state. It is easy for a person to discriminate, and erroneous operation can be prevented.

  In the treatment device according to the embodiment, the guide portion 13 is preferably made of a light-shielding material. However, the guide portion is not limited to this, and the guide portion is made of a material that partially transmits light from the irradiation portion. Structure, specifically, even when the irradiation intensity from the irradiation unit is maximum, the light transmitted through the guide unit is guided by a partially translucent material that attenuates to a safe level even if it enters the eyes. It can also be set as the structure which forms a part. In addition, in the case where a highly irradiating part such as an LED is used and only light with a safe intensity is irradiated even if it enters the eyes other than the opening in front of the irradiating part, the guide part is made more transparent. A high material can also be used, and when the irradiated light is visible light, it is easier for the user to grasp the operation state in which the light is irradiated through the guide portion.

  Moreover, in the treatment device according to the embodiment, the suction is continuously performed by the pump 50 as the suction means in the operating state, but the present invention is not limited to this. The pump suction operation can be temporarily stopped at a predetermined time interval or the suction force can be reduced to reduce the light irradiation intensity and make it easier to separate the opening peripheral edge of the guide part from the skin. In addition to being able to easily shift the treatment target position to other positions on the skin at an appropriate timing and efficiently performing treatment on each position of the skin, the drawing to the guide portion by suction and release from the skin are repeated. This can give the skin a massage effect such as blood circulation promotion.

  Further, in the treatment device according to the embodiment, the irradiation unit 12 is configured to uniformly adjust the irradiation intensity by the control circuit 16 according to the suction load of the pump 50. When using multiple types of light sources that emit light of different wavelengths such as light and infrared light, the adjustment range of the irradiation intensity varies depending on the wavelength of the light. For example, the adjustment range is large for infrared light and visible light is Can be adjusted by reducing the adjustment width. In particular, when the irradiation intensity during treatment is such that the visible light is not dazzling for the eyes, the light having a wavelength that has a large influence on the eyes (infrared light or ultraviolet light) is adjusted, but there is no adverse effect on the eyes. You may make it irradiate visible light as it is, without adjustment.

  Further, in the treatment device according to the embodiment, the skin of the current detection resistor 14 corresponding to the state where the skin is in close contact with the peripheral edge portion 13a by the suction of the pump 50, the skin closes the opening, and the inside of the guide portion 13 is completely sealed. When the potential of the current detection resistor 14 reaches a threshold value equal to or greater than this threshold value, control is performed to increase the light irradiation intensity to a level suitable for treatment. Thus, the threshold can be set in correspondence with a state in which a part of the skin enters the guide portion by suction and the distance between the skin and the irradiation portion is reduced (see FIG. 6C). By increasing the irradiation intensity for the first time in a state where light can be irradiated to the skin, the safety is further improved and the light is irradiated with high irradiation intensity while maintaining the treatment effect on the skin. Shorten time It can be preferable in terms of suppressing the power consumption and exhaustion deterioration of a light source constituting the illumination section.

  In each of the drawings, the treatment device according to the present embodiment includes the treatment unit 20 including the irradiation unit 22 and the guide unit 23, and the stand unit 25 including the pump unit 50 and the power supply unit 60, as in the first embodiment. On the other hand, the difference is that the skin is in contact with the opening peripheral portion 23a of the guide portion 23 from the pressure sensor 24 as the detection portion and the change in the pressure in the guide portion 23 obtained by the pressure sensor 24. And a control unit 26 for adjusting the light irradiation intensity in the irradiation unit 22 is provided.

  Like the first embodiment, the treatment unit 20 includes a main body unit 21, an irradiation unit 22, and a guide unit 23, and the pressure sensor 24 is arranged on the treatment surface unit 21b of the main body unit 21 as a different point. It has the structure which is made.

  The pressure sensor 24 is a known sensor such as a diaphragm type that detects the pressure inside the guide portion 23 that changes due to suction by the pump 50, and detailed description thereof is omitted. The pressure sensor 24 is disposed on the treatment surface portion 21b so as to face the guide portion 23, and detects the pressure in the guide portion 23 that changes depending on the presence or absence of contact between the peripheral edge portion 33a and the skin while suction is performed. .

  As in the first embodiment, the stand unit 25 includes a pump 50, a power source unit 60, and a housing 70. The difference is that the stand unit 25 differs depending on the detection state of the pressure sensor 24 serving as the detection unit. It has a structure provided with the control part 26 which adjusts the intensity | strength irradiated with the light from the irradiation part 22. FIG.

  The control unit 26 performs control for adjusting the light irradiation intensity by changing the power supplied to the irradiation unit 22 according to the pressure value in the guide unit 23 detected by the pressure sensor 24. When the treatment part 20 is brought close to the skin, when the entire circumference of the peripheral part 23a of the opening in the guide part 23 comes into contact with the skin, external air is less likely to enter the guide part 23, resulting in a negative pressure. The pressure in the guide unit 23 further decreases, and the detected value of the pressure sensor 24 reaches a predetermined value. The control unit 26 sets this value as a threshold value in advance, and supplies the irradiation unit 22 with a pressure value below this value. Control is performed to increase the power and increase the light irradiation intensity. On the contrary, in the state where the peripheral edge portion 23a of the opening in the guide portion 23 is not in contact with the skin, the inflow of air into the guide portion 23 may occur, so that the pressure value detected by the pressure sensor 24 is greater than the threshold value. The control unit 26 suppresses the irradiation intensity of the light to the first irradiation intensity that does not have a harmful effect even if light enters the human eye.

  The state in which the detected pressure of the pressure sensor 24 is equal to or less than the threshold corresponds to a situation in which the peripheral edge portion 23a of the opening in the guide portion 23 is all in contact with the skin and the light exiting the opening of the guide portion 23 does not reach other than the skin. In this case, the control unit 26 increases the power supplied to the irradiating unit 22 and increases the light irradiation intensity in the irradiating unit 22, thereby enhancing the treatment effect of the light on the skin.

  On the contrary, when the detected pressure of the pressure sensor 24 exceeds the threshold value, the skin is not in contact with the peripheral edge portion 23a of the opening in the guide portion 23, and the light exiting the opening of the guide portion 23 may reach other than the skin. In this case, the control unit 26 keeps the power supplied to the irradiation unit 22 small, and the irradiation intensity of the irradiation unit 22 is maintained at a safe low level even if light enters the eyes. . At the same time, the power consumption is also reduced as the irradiation intensity of the light from the irradiation unit 22 is reduced.

  Next, the operation state of the treatment device according to the present embodiment will be described. As a premise, as in the first embodiment, the treatment device 2 is activated when the power is turned on, the user holds the treatment portion 20 and directs the opening of the guide portion 23 toward the treatment portion, and an operation instruction is input by the user. It is assumed that the treatment operation can be started.

  When the user turns on the operation switch 21d, suction by the pump 50 is started, and at the same time, irradiation of light in the irradiation unit 22 is also started. In the initial state, the light irradiation intensity is low and safe even if it enters the eyes. In a state where the opening peripheral edge portion 23a of the guide portion 23 is separated from the skin, air can flow into the guide portion 23. Therefore, the pressure value detected by the pressure sensor 24 is larger than the threshold value, and the control portion 26 As a situation where the skin is not in contact with the peripheral portion 23a, the power supplied to the irradiation unit 22 is kept small, and the light irradiation intensity in the irradiation unit 22 is low.

  When the peripheral edge 23 of the opening is brought into contact with the skin, the skin is attracted to the opening by the suction of the pump 50 and comes into close contact with the peripheral edge 23a, and it is difficult for outside air to flow into the guide 23 together. The pressure in the guide unit 23 where the suction of the pump 50 is continued further becomes the negative pressure side, and the value of the pressure detected by the pressure sensor 24 is greatly reduced to be equal to or less than the threshold value. 23a is determined to be in a state where the entire circumference is in contact with the skin, the power supplied to the irradiation unit 22 is increased, and the light irradiation intensity is increased to a state suitable for treatment.

  At the same time, a part of the skin enters the guide part 23 while deforming the guide part 23 by suction, and the degree of adhesion between the skin and the opening peripheral edge part 23a of the guide part 23 increases, and the skin and the guide part A safe state in which the opening peripheral edge portion 23a of the 23 does not leave and the light exiting the opening does not reach other than the skin is easily realized without an operation of pressing the guide portion 23 of the user strongly against the skin. The distance between the skin that has entered and the irradiation unit 22 is also reduced, so that the skin can receive more light from the irradiation unit 22 and the treatment effect by light is further enhanced.

  When the opening peripheral edge 23a of the guide part 23 is separated from the skin in order to interrupt the treatment or change the treatment position, air can flow into the guide part 23, thereby increasing the pressure in the guide part 23. When the value of the pressure detected by the sensor 24 exceeds the threshold value, the control unit 26 determines that the skin is not in contact with the peripheral portion 23a, and shifts to a state in which the power supplied to the irradiation unit 22 is suppressed. Thus, since the power supplied to the irradiation unit 22 is suppressed by the control unit 26, the light irradiation intensity is lowered to a safe state without affecting the eyes, and the light that has exited the opening of the guide unit 23 is directly seen by the eyes. Even if it enters, there is no negative effect on the eyes. When the treatment is completely completed, as in the first embodiment, when the user turns the operation switch 21d to the OFF state, the suction by the pump 50 and the light irradiation in the irradiation unit 22 are stopped.

  Thus, in the treatment device according to the present embodiment, when the pump 50 performs suction, the pressure in the guide portion 23 varies depending on whether the opening peripheral edge portion 23a of the guide portion 23 is not in contact with the skin or not. While the pump 50 performs suction using the different states, the pressure sensor 24 as the detection unit detects a pressure change in the guide unit 23, and the control unit 26 determines the light irradiation intensity based on the detection result. Since the entire periphery of the opening peripheral edge 23a of the guide portion 23 is in contact with the skin and the light exiting the opening does not reach other than the skin, the peripheral edge 23a leaves the opening away from the skin. In the situation where the danger of entering the eyes of the light is correctly identified and the appropriate irradiation intensity adjustment can be performed, the safety during treatment with light irradiation can be reliably maintained, and the light reaches other than the skin Reduces power consumption by reducing the light intensity. Power saving as treatment instrument Te can be reduced.

(Third embodiment of the present invention)
A treatment device according to a third embodiment of the present invention will be described with reference to FIGS. FIG. 9 is a longitudinal sectional view of a main part of the treatment part during massage of the treatment device according to the present embodiment, FIG. 10 is a perspective view of a guide part in the treatment device according to the present embodiment, and FIG. 11 is a treatment device according to the present embodiment. FIG.

  In each of the drawings, the treatment device according to the present embodiment includes the treatment unit 30 having the irradiation unit 32 and the guide unit 33, and the stand unit 35 including the pump unit 50 and the power supply unit 60, as in the first embodiment. On the other hand, as a different point, the detection unit includes a plurality of pairs of detection electrodes 34 arranged on the opening peripheral edge portion 33a of the guide portion 33, and guides from a change in resistance value between the detection electrodes 34. It has the structure provided with the control part 36 which determines whether the skin is contacting the opening peripheral part 33a of the part 33, and adjusts the irradiation intensity | strength of the light in the irradiation part 32. FIG.

  As in the first embodiment, the treatment unit 30 includes a main body 31, an irradiation unit 32, and a guide unit 33. The difference is that the detection electrode 34 is a peripheral portion of an opening in the guide unit 33. A plurality of pairs are arranged in 33a.

  The detection electrodes 34 are arranged in a plurality of pairs so that the peripheral edge portion 33a of the opening in contact with the skin of the guide portion 33 made of an elastic material can be in contact with the skin and a pair of the electrodes located at opposite positions across the opening. The resistance relating to the energized state between the pair of electrodes that changes between the state in which the skin is in contact with the peripheral portion 33a of the opening in the guide portion 33 and the state in which the skin is not approaching the peripheral portion 33a. It is the structure which detects a value. The detection electrode 34 is disposed by attaching a conductor such as metal to the surface of the guide portion 33 which is an elastic body such as rubber or by forming a thin film of the conductor, and the guide portion 33 is attached to the main body portion 31. Thus, it is a mechanism that is electrically connected to the conductor on the main body 33 side and is electrically connected to the controller 36 at the same time. Since these detection electrodes 34 are accompanied by suction during the treatment of bringing the peripheral edge portion 33a into contact with the skin, the peripheral edge portion 33a can be brought into close contact with the skin, and an energized state between the electrodes via the skin can be reliably obtained. Thus, the difference between the peripheral edge 33a and the skin can be clarified.

  As in the first embodiment, the stand unit 35 includes a pump 50, a power source unit 60, and a housing 70. The difference is that the stand unit 35 differs depending on the detection state of the detection electrode 34 serving as the detection unit. It has the structure provided with the control part 36 which adjusts the intensity | strength irradiated with the light from the said irradiation part 32. FIG.

  The control unit 36 performs control for adjusting the light irradiation intensity by changing the power supplied to the irradiation unit 32 in accordance with the resistance value between the pair of detection electrodes 34. When the entire periphery of the peripheral edge 33a of the opening in the guide 33 is in contact with the skin, the control unit 36 decreases the resistance value between the pair of detection electrodes 34 and reaches a predetermined value. Control is performed in advance to increase the light irradiation intensity by increasing the power supplied to the irradiation unit 32 with a resistance value less than this. On the contrary, in a state where the peripheral edge portion 33a of the opening in the guide portion 33 is not in contact with the skin, the resistance value between the detection electrodes 34 is larger than the threshold value, and the control portion 36 sets the light irradiation intensity to human. Even if light enters the eyes, the first irradiation intensity is suppressed so as not to have a harmful effect.

  When the resistance value between the detection electrodes 34 is equal to or less than the threshold value, the skin is in contact with the entire circumference of the peripheral edge portion 33a of the opening in the guide portion 33, and the light exiting from the opening of the guide portion 33 does not reach other than the skin. In this case, the control unit 36 increases the power supplied to the irradiating unit 32 and increases the irradiation intensity of light in the irradiating unit 32, thereby enhancing the treatment effect of light on the skin.

  Conversely, when the resistance value between the detection electrodes 34 exceeds the threshold value, the skin is not in contact with the peripheral edge portion 33a of the opening in the guide portion 33, and the light exiting the opening of the guide portion 33 reaches other than the skin. In this case, the control unit 36 keeps the power supplied to the irradiation unit 32 small, and the irradiation intensity of the irradiation unit 32 is maintained at a low level that is safe even if light enters the eyes. Is done. At the same time, the power consumption is reduced as the irradiation intensity of light from the irradiation unit 32 is reduced.

  Next, the operation state of the treatment device according to the present embodiment will be described. As a premise, similar to the first embodiment, the treatment device 3 is activated when the power is turned on, the user holds the treatment portion 30 and directs the opening of the guide portion 33 toward the treatment portion, and an operation instruction is input by the user. It is assumed that the treatment operation can be started.

  When the user turns on the operation switch 31d, suction by the pump 50 is started, and at the same time, irradiation of light in the irradiation unit 32 is also started. In the initial state, the light irradiation intensity is low and safe even if it enters the eyes. In the state where the opening peripheral portion 33a of the guide portion 33 is separated from the skin, the resistance value between the detection electrodes 34 disposed on the opening peripheral portion 33a is infinite and is larger than the threshold value. As a situation where the skin is not in contact with the peripheral portion 33a, the power supplied to the irradiation unit 32 is kept small, and the light irradiation intensity in the irradiation unit 32 is low.

  When the opening peripheral portion 33a is brought into contact with the skin, the skin is attracted to the opening by the suction of the pump 50 and comes into close contact with the peripheral portion 33a, and all the pairs of the opening peripheral portion 33a of the guide portion 33 are detected. When the resistance value is significantly reduced between the electrodes 34 for use and becomes equal to or less than the threshold value, the control unit 36 determines that the entire periphery of the peripheral portion 33a is in contact with the skin, and increases the power supplied to the irradiation unit 32. Thus, the irradiation intensity of light increases to a state suitable for treatment.

  At the same time, a part of the skin enters into the guide portion 33 by suction, the degree of adhesion between the skin and the opening peripheral portion 33a of the guide portion 33 is increased, and the skin and the opening peripheral portion 33a of the guide portion 33 are A safe state in which the light exiting the opening without leaving does not reach any part other than the skin is easily realized without the operation of pressing the guide part 33 of the user strongly against the skin, and the skin and the irradiation part entering the guide part 33 The distance between 32 is also reduced, and the skin can receive more light from the irradiation unit 32, and the treatment effect by light is further enhanced.

  When the opening peripheral edge 33a of the guide part 33 is separated from the skin in order to interrupt the treatment or change the treatment position, the resistance between the detection electrodes 34 of the opening peripheral part 33a of the guide part 33 increases, and the resistance is the threshold value. The control unit 36 determines that the skin is not in contact with the peripheral portion 33a, and shifts to a state in which the power supplied to the irradiation unit 32 is suppressed. Thus, since the power supplied to the irradiation unit 32 is suppressed by the control unit 36, the irradiation intensity of the light is lowered to a safe state that does not affect the eyes. Even if it enters, there is no negative effect on the eyes. When the treatment is completely completed, as in the first embodiment, when the user turns the operation switch 31d to the OFF state, the suction by the pump 50 and the light irradiation in the irradiation unit 32 are stopped.

  Thus, in the treatment device according to the present embodiment, a plurality of pairs of detection electrodes 34 paired with the opening peripheral edge portion 33a of the guide portion 33 are arranged, and the opening peripheral edge portion 33a of the guide portion 33 is in contact with the skin. A change in the resistance value related to the energization state between the detection electrodes 34 is detected during light irradiation by utilizing the change in the energization state between the pair of detection electrodes 34 depending on whether there is no contact or no contact. And since the control part 36 adjusts the irradiation intensity | strength of light based on this detection result, the opening peripheral part 33a whole periphery of the guide part 33 contact | abuts skin, and the light which exited opening does not reach other than skin Can be reliably discriminated from the state where the peripheral edge 33a is separated from the skin and is in danger of entering the eyes of light exiting the opening. Appropriate adjustment and limitation of light intensity according to the presence or absence of contact In addition, the detection at the detection electrode 34 as the detection unit does not depend on the suction state, and the irradiation intensity of light can be adjusted even in a state where the suction is stopped by mistake, so that safety and reliability during treatment of irradiating light can be improved. Can be improved.

  Note that, in the treatment device according to the embodiment, the detection electrode 34 is used as a detection unit, a change in resistance value according to the energization state between the electrodes is detected, and the light irradiation intensity is adjusted by the control unit 36. In addition to this, instead of the detection electrode, as the detection part, one or a plurality of pressure sensors are provided over the entire peripheral edge of the opening in the guide part to detect a pressure change associated with contact with the skin. It is also possible to adopt a configuration in which the relative pressure applied to the peripheral surface is different between the case where the peripheral edge of the guide opening is not in contact with the skin and the case where it is in contact with the skin. The pressure sensor detects a change in pressure, and the control unit adjusts the light irradiation intensity based on the detection result. The light that goes out of the skin does not reach anything but the skin It is possible to properly determine the state and the state in which there is a danger of entering the eyes of the light that has left the skin and the peripheral edge away from the skin, and appropriate irradiation intensity adjustment can be performed, and safety during treatment with light irradiation It can be maintained more reliably.

  In addition, as another detection unit, a sensor that detects a change in a physical quantity related to deformation accompanying contact with the skin of the peripheral edge of the opening in the guide part formed of a flexible material, for example, a change in the amount of strain related to the deformation. As described above, the control unit adjusts the irradiation intensity of light based on the detection result of the sensor, so that the appropriate irradiation intensity can be adjusted as in the embodiment, and safety during treatment can be ensured. .

(Fourth embodiment of the present invention)
A treatment device according to a fourth embodiment of the present invention will be described with reference to FIGS. FIG. 12 is a longitudinal sectional view of a main part of a treatment unit in the treatment device according to this embodiment, and FIG. 13 is a block diagram of the treatment device according to this embodiment.

  In each of the drawings, the treatment device according to the present embodiment includes a treatment unit 40 having an irradiation unit 42 and a guide unit 43, and a stand unit 45 incorporating a pump unit 50 and a power supply unit 60, as in the first embodiment. On the other hand, the difference is that the skin is substantially in contact with the opening peripheral portion 43a of the guide portion 43 due to the distance measuring sensor 44 as the detecting portion and the change in the distance to the skin obtained by the distance measuring sensor 44. And a control unit 46 that adjusts the light irradiation intensity in the irradiating unit 42.

  Like the first embodiment, the treatment unit 40 includes a main body 41, an irradiation unit 42, and a guide unit 43. The difference is that the distance measuring sensor 44 is disposed on the treatment surface 41b of the main body 41. It has the structure arranged.

  The distance measuring sensor 44 includes a light projecting unit 44a that emits light for measurement, and a light receiving unit 44b that receives the return light reflected by the measurement object from the light projecting unit 44a. This is a known photoelectric / reflective sensor that measures the distance between the sensor position and the object to be measured based on the amount of light received at, and a detailed description thereof is omitted. The distance measuring sensor 44 is disposed on the treatment surface portion 31b with the light projecting portion 44a and the light receiving portion 44b separated from each other by a predetermined distance, and detects the distance between the sensor and the skin close to the peripheral edge portion 43a of the guide portion 43. is there.

  As in the first embodiment, the stand unit 45 includes a pump 50, a power source unit 60, and a housing 70. The difference is that the stand unit 45 differs depending on the detection state of the distance measuring sensor 44 serving as the detection unit. It has the structure provided with the control part 46 which adjusts the irradiation intensity | strength of the light from the said irradiation part 42. FIG.

  The control unit 46 executes control for adjusting the irradiation intensity of light by changing the power supplied to the irradiation unit 42 according to the value of the distance from the sensor detected by the distance measuring sensor 44 to the skin. . When the treatment part 40 is brought closer to the skin, the distance measurement is performed in a state in which the entire circumference of the peripheral part 43a of the opening in the guide part 43 is close to the skin, for example, the distance between the peripheral part 43a and the skin is about 5 mm. Although the distance value obtained by the sensor 44 reaches a predetermined value, the control unit 46 sets this value as a threshold value in advance, and increases the power supplied to the irradiation unit 42 when the distance is less than this value. Execute control to increase strength. Conversely, in the state where the peripheral edge 43a of the opening in the guide portion 43 is not close to the skin, the distance value obtained by the distance measuring sensor 44 is larger than the threshold value, and the control portion 46 determines the light irradiation intensity. Is suppressed to the first irradiation intensity that does not have a harmful effect even if light enters the human eye.

  When the distance value obtained by the distance measuring sensor 44 is equal to or less than the threshold value, the peripheral edge portion 43a of the opening in the guide portion 43 comes into contact with the skin or approaches a very close distance and exits the opening of the guide portion 43. In this case, the control unit 46 increases the power supplied to the irradiation unit 42 and increases the irradiation intensity of the light in the irradiation unit 42, thereby reducing the light to the skin. Enhance the treatment effect.

  Conversely, when the distance value obtained by the distance measuring sensor 44 exceeds the threshold value, the skin is separated from the peripheral edge portion 43a of the opening in the guide portion 43, and the light emitted from the opening of the guide portion 43 is not on the skin. In this case, the control unit 46 keeps the power supplied to the irradiation unit 42 small, and the irradiation intensity of the irradiation unit 42 is a low level that is safe even if light directly enters the eyes. Maintained. At the same time, the power consumption also decreases as the irradiation intensity of light from the irradiation unit 42 decreases.

  Next, the operation state of the treatment device according to the present embodiment will be described. As a premise, similar to the first embodiment, the treatment device 4 is activated when the power is turned on, the user holds the treatment portion 40 and directs the opening of the guide portion 43 toward the treatment portion, and an operation instruction is input by the user. It is assumed that the treatment operation can be started.

  When the user turns on the operation switch 41d, suction by the pump 50 is started, and at the same time, irradiation of light in the irradiation unit 42 is also started. In the initial state, the light irradiation intensity is low and safe even if it enters the eyes. In the state where the opening peripheral edge 43a of the guide part 43 is separated from the skin, the distances between the light projecting part 44a and the light receiving part 44b forming the distance measuring sensor 44 in the guide part 43 and the skin are increased and detected. Since the value of the distance is larger than the threshold value, the control unit 46 suppresses the power supplied to the irradiation unit 42 as a situation where the skin does not approach the peripheral portion 43a, and the irradiation intensity of light in the irradiation unit 42 becomes low. ing.

  When the opening edge portion 43a is brought close to the state of being substantially in contact with the skin, the distance between the distance measuring sensor 44 in the guide portion 43 and the skin is reduced, the value of the distance detected by the sensor is also reduced, and is below the threshold value. The control unit 46 determines that the peripheral edge 43a and the skin are sufficiently close to each other and the light emitted from the opening of the guide unit 43 does not reach any part other than the skin, and increases the power supplied to the irradiation unit 42 to The irradiation intensity is increased to a state suitable for treatment.

  Further, when the entire periphery of the opening peripheral edge 43a is brought into contact with the skin, the skin is attracted to the opening by the suction of the pump 50 and comes into close contact with the peripheral edge 43a. At the same time, a part of the skin enters into the guide portion 43 by suction, the degree of adhesion between the skin and the opening peripheral portion 43a of the guide portion 43 increases, and the skin and the opening peripheral portion 43a of the guide portion 43 A safe state in which the light that exits the opening without leaving it does not reach other than the skin is easily realized without the operation of pressing the guide portion 43 of the user strongly against the skin, and the skin and the irradiation portion that have entered the guide portion 43 The distance between 42 is also reduced, so that the skin can receive more light from the irradiation unit 42 and the treatment effect by light is further enhanced.

  When the opening peripheral edge 43a of the guide part 43 is separated from the skin in order to interrupt the treatment or change the treatment position, the value of the distance detected by the sensor increases, and the control part 46 becomes the peripheral part by exceeding the threshold value. It determines with the skin not approaching to 43a, and transfers to the state which suppresses the electric power supplied to the irradiation part 42. FIG. Thus, since the power supplied to the irradiation unit 42 is suppressed by the control unit 46, the irradiation intensity of the light is lowered to a safe state without affecting the eyes, and the light that has exited the opening of the guide unit 43 is directly seen by the eyes. Even if it enters, there is no negative effect on the eyes. When the treatment is to be completed completely, as in the first embodiment, when the user turns off the operation switch 41d, the suction by the pump 50 and the light irradiation in the irradiation unit 42 are stopped.

  As described above, in the treatment device according to the present embodiment, the distance measuring sensor 44 capable of detecting the distance to the skin is disposed as the detection unit, and the opening peripheral edge 43a of the guide unit 43 is separated from the skin. Using the fact that the distance between the skin and the sensor becomes different when approaching, the distance sensor 44 detects a change in distance while irradiating light, and the control unit 46 detects the light based on the detection result. Since the opening peripheral edge 43a of the guide portion 43 is in contact with and / or close to the skin and the light exiting the opening does not reach other than the skin, the peripheral edge 43a is separated from the skin. Appropriate irradiation intensity adjustment can be performed by correctly discriminating from the state in which there is a risk of entering the eyes of light exiting the aperture. In addition, since the detection by the distance measuring sensor 44 as a detection unit does not depend on the suction state and does not require contact between the peripheral portion 43a and the skin, it is possible to adjust the light irradiation intensity even when the suction is stopped by mistake. In addition to improving the safety and reliability during the treatment of irradiating light, the light irradiation intensity is appropriately adjusted in situations where the light does not reach other than the skin even if the peripheral portion 43a is not completely in contact with the skin. Thus, the treatment operation can be performed efficiently.

  In the treatment device according to the fourth embodiment, as the distance measuring sensor 44, a device that measures the distance by projecting light onto the object and receiving the return light reflected by the object to be measured is used. However, the measurement is not limited to this, and the measurement may be performed using ultrasonic waves or radio waves instead of light.

  In the treatment device according to each of the first to fourth embodiments, the guide portions 13, 23, 33, and 43 are deformed with the skin sucked by the suction of the pump 50, and approach the skin irradiation portion. Although it is set as the structure made from the flexible material to promote, it can also be set as the structure formed from the hard material which is not restricted to this but is highly rigid and does not deform | transform easily. Furthermore, when this guide part is made of a material that does not deform, the peripheral part of the opening in the guide part and the other part are separated, and the peripheral part can be moved in the cylinder axis direction with respect to the other part, while the detection part The sensor can be configured to include a sensor or a switch that detects relative displacement with respect to the other part accompanying the contact with the skin of the peripheral edge of the opening of the guide part, and the case where the peripheral part is not in contact with the skin. By utilizing the fact that the positional relationship of the peripheral portion with respect to the other portions of the guide portion is different, the displacement of the peripheral portion is detected by a sensor or switch that constitutes the detection portion while irradiating light, and light is detected based on the detection result. By adjusting the irradiation intensity, the entire periphery of the opening edge of the guide part is in contact with the skin and the light that exits the opening does not reach other than the skin, and the edge part leaves the skin and leaves the opening. There is a danger of light entering the eyes Certainly can do on purpose of discrimination, the adjustment of the irradiation intensity of the light can be appropriately performed, it can be maintained safety during treatment more reliably.

  Moreover, in the treatment device which concerns on each said 1st thru | or 4th embodiment, although it is set as the structure which uses LED as an irradiation part, it is not restricted to this, Other light sources, such as a strobe light, an infrared heater, a laser element, are used. It may be used, and the treatment effect is not limited to the skin. Depending on the wavelength of the emitted light and the irradiation intensity, the treatment effect may be applied to deeper body tissues (such as visceral fat). . Further, the irradiating unit is configured such that an LED serving as a light source is directly attached to the treatment surface portion 11b, and the light source directly faces the space in the guide portion. It is configured to irradiate light through a window portion made of a translucent material or to reach a treatment surface portion from a light source built in the back of the main body portion through a light transmission means such as an optical fiber and irradiate light into the guide portion. You may do it.

  Moreover, in the treatment device according to each of the first to fourth embodiments, the motor-driven electric pump 50 is used as the suction means for sucking the air in the guide portion. It is also possible to adopt a configuration using a type of pump that performs suction and discharge, and the structure of the entire treatment device can be simplified.
