Description

Nostril insertion device with electrodes {NOSTRILS INSERTION WITH ELECTRODES}

The present invention relates to a nostril insertion device that generates special microcurrent electromagnetic waves using electrodes.

Rhinitis is a disease that refers to inflammation inside the nose (intranasal cavity). It is largely divided into allergic rhinitis and chronic rhinitis, and there is no standard to clearly distinguish between the two types of rhinitis. Rhinitis itself is difficult to consider a life-threatening, fatal disease, but it is very difficult to cure and can be said to be a disease that significantly reduces the quality of life.

In fact, allergic rhinitis has a prevalence of 10-20% in the West and 15% in Korea, and the prevalence is gradually increasing due to environmental changes such as air pollution, increased use of food additives, and urbanization. Therefore, management of rhinitis in daily life is more important than anything else, and it is important to make efforts to resolve the fundamental cause of rhinitis and alleviate symptoms caused by rhinitis by improving lifestyle habits.

It is a rhinitis treatment device commonly used for the purpose of alleviating and treating rhinitis symptoms. It is an ultrasonic spray method that sprays therapeutic drugs such as saline solution, benzenthonium chloride, alcohol, etc. into small vapor particles using ultrasonic waves, and therapeutic drugs. Products manufactured using the compressed air spray method, which uses water vapor generated by heating saline solution to a certain temperature and blows out as the water vapor expands, are widely used.

Among these, the compressed air spray method uses air pressure to finely and powerfully spray the therapeutic drug, and is generally used because it has superior therapeutic effects compared to the ultrasonic spray method.

However, rhinitis treatment devices manufactured using ultrasonic spraying and compressed air spraying methods may consume excessive amounts of medication each time they are used, and in addition, rhinitis treatment devices are designed to spray liquid drugs, which are foreign substances, directly into the affected area in the nose. The shock when spraying causes irritation inside the nose, which can cause other rhinitis diseases. As a result, it is not comfortable to use, so children and the elderly who have relatively many rhinitis diseases avoid using it. Since it must be used in certain conditions, it has the disadvantage of causing limitations in use.

Recently, a laser rhinitis treatment device has been developed through low-level laser therapy (LLLT) to irradiate a semiconductor laser into the nasal cavity to improve allergic rhinitis symptoms through the biostimulatory effect of the laser. However, due to the direct nature of the laser, There is a problem in that the treatment range in which the laser is irradiated is narrow and treatment efficiency is therefore low.

Hereinafter, a nostril insertion device according to an embodiment of the present invention will be described with reference to the drawings related to embodiments of the present invention.

FIGS. 1 and 2 are diagrams showing a nostril insertion device according to an embodiment of the present invention, and FIGS. 3A and 3B are diagrams illustrating the biofilm removal effect of a driving signal generated by mixing AC signals and DC signals. .

Referring to Figure 1, the nostril insertion device 1 according to an embodiment of the present invention includes an insertion device 10, a power supply 20, and a connection portion connecting the insertion device 10 and the power supply 20. (30) may be included.

In particular, the signal supply unit 40 generates a driving signal by mixing an Alternating Current (AC) signal and a Direct Current (DC) signal. Accordingly, the driving signal contains both AC and DC components, and a synergy effect and resonance occurs due to simultaneous application of AC and DC components, increasing the effect of removing biofilm, which causes inflammation. It can be.

Referring to Figure 3a, the electric field due to the DC component increases the structural stress of the biofilm by inducing an imbalance in the local charge distribution, and the electric field due to the AC component increases the permeability of the external protector through the generation of specific vibrations. You can do it.

The synergistic effect of these AC and DC components can be seen in Figure 3b. In other words, compared to the biofilm removal effect when the electric field by the AC component and the electric field by the DC voltage are provided separately, the removal of biofilm is achieved when the electric field by the AC component and the electric field by the DC voltage are provided simultaneously. It can be seen that the effect is significantly superior.

Additionally, the cover 150 may have elasticity, and for this purpose, it may be formed of an elastic material. For example, when the insertion device 10 is inserted into the user's nose, the cover 150 is deformed in response to the shape of the user's nose, so the gap between the first insertion part 10a and the second insertion part 10b, etc. This may change, and when the insertion device 10 is removed from the user's nose, the deformed shape of the cover 150 may be restored to its original state. At this time, the support portion 330 of the connection portion 30 coupled to the cover 150 may also be formed of an elastic material.

Each of the first insertion part 10a and the second insertion part 10b may include a body 120 and a head 130 covering the upper surface of the body 120.

The body 120 and the head 130 may be formed of a synthetic resin material, and by adding some graphene to the synthetic resin, antibacterial properties, far-infrared ray emission function, and water repellent function can be implemented. Additionally, the head 130 may be made of a material that allows light emitted from the light emitting unit 12 to pass through, or may be made of a material that allows light to pass through.

The electrodes 11a and 11b may provide electromagnetic waves based on the electrical energy of the driving signal, and these electromagnetic waves may have an electrical effect on the user.

If the gap (G) between the first electrode (11a) and the second electrode (11b) is set to be less than 0.1 mm or more than 20 mm, expect a biofilm removal effect by electromagnetic waves generated from the electrodes (11a, 11b). It can be difficult.

The first electrode 11a and the second electrode 11b may be formed to a size suitable for being placed in the body 120 of a size suitable for use in a user's nostril.

It can be from mm to 50 mm. Additionally, the second electrode 11b and the first electrode 11a may be formed to have the same size.

On the other hand, when the width and length of the first electrode 11a and the second electrode 11b are set to less than 0.1 mm, the oral care effect by the electric field may be weak.

According to an embodiment of the present invention, the first electrode 11a and the second electrode 11b may have a shape that partially protrudes from the body 120. In this case, the first electrode 11a is connected to the body 120. It may be in a form that protrudes to a height of 0.1 mm to 15 mm based on the surface. At this time, the second electrode 11b may be set at the same height as the first electrode 11a.

If the height of the electrodes (11a, 11b) is set to less than 0.1 mm, there is a possibility that the electrodes (11a, 11b) may be buried inside the body 120 during the insert injection molding process. .

It is one end of the electrode area that protrudes and extends in another direction opposite to the one direction, and the third end 113a is located above the center area of the first electrode 11a (in a direction perpendicular to the one direction and the other direction). It may be one end of the electrode area formed by protruding and extending. Here, the central area of the first electrode 11a may be an area connected to one end of the first connection electrode 131, which will be described later.

FIG. 8 is a diagram showing the internal configuration of a power supply device according to an embodiment of the present invention, and FIGS. 9A to 9C are diagrams showing the waveform of a signal according to an embodiment of the present invention. In particular, Figure 9a shows a filtered AC signal (Sac'), Figure 9b shows a DC signal (Sdc), and Figure 9c shows a mixture of the filtered AC signal (Sac') and DC signal (Sdc). The driving signal (Vd) is shown.

Referring to FIG. 8 , the power device 20 may include a signal supply unit 40 and a battery 50, and the battery 50 may provide a battery voltage (Vb) to the signal supply unit 40.

The signal supply unit 40 may include a DC-DC converter 41, a signal generator 42, a filter 43, and a calibration unit 44, and may further include a voltage divider 45. there is.

The DC-DC converter 41 can receive the battery voltage (Vb) from the battery 50, convert the battery voltage (Vb) into an output voltage (Vo) at a predetermined level, and output it.

The signal generator 42 may be implemented using a known configuration capable of generating an AC signal, such as an oscillator or function generator.

For example, the AC signal (Sac) can be set to a frequency of 1KHz to 1000MHz. This is because when the AC signal (Sac) is set to a low frequency of less than 1 KHz, the biofilm removal effect is reduced, and even when the AC signal (Sac) is set to an ultra-high frequency exceeding 1000 MHz, the biofilm removal effect is reduced. Meanwhile, the frequency of the AC signal (Sac) can be set to a frequency of 5 MHz to 15 MHz, which is suitable for removal of biofilm.

Additionally, the amplitude of the AC signal (Sac) may be set to 0.1 mV to 10 V, which is suitable for removal of biofilm, but is not limited thereto. This is because it is difficult to expect a biofilm removal effect if the amplitude of the AC signal (Sac) is less than 0.1mV.

The filter 43 may perform a filtering operation on the AC signal (Sac) generated by the signal generator 42. For example, the filter 43 includes a band pass filter and can convert an AC signal (Sac) in the form of a sawtooth wave into an AC signal (Sac') in the form of a sine wave. there is. However, the type of filter 43 is not limited to this, and various types of filters may be employed depending on the design structure.

The calibration unit 44 may generate a driving signal (Vd) by mixing the DC signal (Sdc) with the AC signal (Sac') supplied through the filter 43. For example, the calibration unit 44 may be implemented as an operating amplifier capable of summing (or overlapping) an AC signal (Sac') and a DC signal (Sdc), but is not limited thereto.

Accordingly, an offset corresponding to the DC signal (Sdc) is generated in the AC signal (Sac'), and a driving signal (Vd) having both AC and DC components can be generated.

Since the driving signal (Vd) contains all the characteristics of the AC signal (Sac), the driving signal (Vd) can be set to a frequency of 1KHz to 1000MHz, and also a frequency of 5MHz to 15MHz, which is more suitable for removing wastes in pores. It can be set to . Additionally, the amplitude of the driving signal (Vd) can be set to 0.1 mV to 10 V.

Referring to FIG. 9A, the calibration unit 440 may receive an AC signal (Sac') having an amplitude of A volt (V) from the filter 43, and the AC signal (Sac') shown in FIG. 9B may be supplied. The final driving signal (Vd) as shown in FIG. 9C can be generated by superimposing the DC signal (Sdc) of B volts (V) as shown.

At this time, the voltage value of the DC signal (Sdc) may be set to be greater than or equal to the amplitude of the AC signal (Sac’). Accordingly, the voltage value of the driving signal (Vd) may be set to 0 or more.

Ultimately, the DC offset value of the driving signal (Vd) may be set to be equal to or greater than the amplitude of the driving signal (Vd).

When the DC offset value of the driving signal (Vd) is less than the amplitude value of the driving signal (Vd), a section occurs in which the voltage of the driving signal (Vd) has a negative value, and in this section, the voltage has a negative value. As a result, loss of electrical energy occurs.

However, as in the embodiment of the present invention, if the DC offset value of the driving signal (Vd) is set to be equal to or larger than the amplitude of the driving signal (Vd), the voltage of the driving signal (Vd) is always '0' or higher, Energy loss can be minimized.

Meanwhile, the DC signal Sdc may be generated by the voltage divider 45. For example, the voltage divider 45 may receive the output voltage (Vo) of the DC-DC converter 41, and perform voltage division on the output voltage (Vo) to generate a DC signal (Sdc). You can.

The voltage divider 45 may be composed of a resistor string to distribute the output voltage Vo, but is not limited thereto.

When the output voltage (Vo) of the DC-DC converter 41 is suitable for direct use in generating the driving signal (Vd), the corresponding output voltage (Vo) can serve as the DC signal (Sdc). In this case, the voltage divider 45 can be omitted, and the output voltage (Vo) of the DC-DC converter 41 can be input to the calibration unit 44.

Figure 10 is a diagram showing the internal configuration of a power supply device according to another embodiment of the present invention.

Referring to FIG. 10, in the power supply device 20 according to another embodiment of the present invention, the signal supply unit 40 may change at least one characteristic of the driving signal Vd in response to the user's control. Additionally, the power device 20 may additionally include a control unit 70 that controls the signal supply unit 40 in response to a user's input.

For example, the characteristics of the driving signal Vd may include the amplitude and DC offset of the driving signal Vd.

That is, the user can set the optimal driving signal (Vd) suitable for the user by adjusting at least one of the amplitude and DC offset of the driving signal (Vd).

At this time, the user's input method for controlling the characteristics of the driving signal (Vd) may be through a switch installed in the power device 20, and the user operates the switch installed in the power device 20, etc. ) can be adjusted or set.

When the setting information of the driving signal (Vd) is input through a switch operation by the user, the control unit 70 sets the signal supply unit 40 so that the driving signal (Vd) has an amplitude value and a DC offset value corresponding to the input setting information. can be controlled.

The control unit 70 can change the amplitude of the AC signal (Sac) by controlling the signal generator 42. Additionally, the control unit 70 may control the voltage value of the DC signal (Sdc) by controlling the DC-DC converter 41 and/or the voltage divider 45. Accordingly, the characteristics of the driving signal Vd may ultimately be changed.

At this time, the control unit 70 may control the voltage divider 45 so that the voltage value of the DC signal (Sdc) is set to be greater than or equal to the amplitude of the AC signal (Sac'), and accordingly, the voltage value of the driving signal (Vd) may be set. can be set to 0 or more.

Meanwhile, according to one embodiment of the present invention, the characteristics of the driving signal (Vd) supplied to the first insertion part (10a) and the characteristics of the driving signal (Vd) supplied to the second insertion part (10b) are set to be the same. It can be. That is, one driving signal Vd output from the signal supply unit 40 may be input to the first insertion unit 10a and the second insertion unit 10b.

According to another embodiment of the present invention, the characteristics of the driving signal (Vd) supplied to the first insertion part (10a) and the characteristics of the driving signal (Vd) supplied to the second insertion part (10b) are set differently. It can be.

In this case, although not shown in the drawing, two signal supply units 40 are provided, so that one signal supply unit 40 generates and outputs the driving signal Vd supplied to the first insertion unit 10a, and the other signal supply unit 40 generates and outputs the driving signal Vd supplied to the first insertion unit 10a. The signal supply unit 40 may generate and output a driving signal (Vd) supplied to the second insertion unit 10b.

Accordingly, the user can input the setting information of the driving signal corresponding to the first insertion part 10a and the setting information of the driving signal corresponding to the second insertion part 10b differently, and the control unit 70 The signal supply unit 40 can be controlled.

Figures 11a and 11b are diagrams showing a signal supply unit according to another embodiment of the present invention.

Referring to FIGS. 11A and 11B, the signal supply unit 60 according to another embodiment of the present invention includes a DC-DC converter 61, a signal generator 62, a voltage drop unit 63, a filter 64, and an offset adjustment unit 65.

The DC-DC converter 61 can receive the battery voltage (Vb), convert the battery voltage (Vb) into an output voltage (Vo) at a predetermined level, and output it.

The signal generator 62 operates based on the voltage supplied from the DC-DC converter 61, and uses the output voltage (Vo) of the DC-DC converter 61 to generate a first AC signal ( Sa1) can be generated.

The signal generator 62 may be implemented using a known configuration capable of generating an AC signal, such as an oscillator or a function generator.

For example, the first AC signal Sa1 may be set to a frequency of 1 KHz to 1000 MHz. If the first AC signal (Sa1) is set to a low frequency of less than 1 KHz, the biofilm removal effect is reduced, and even if the first AC signal (Sa1) is set to an ultra-high frequency of more than 1000 MHz, the biofilm removal effect is reduced. Because. Meanwhile, the frequency of the first AC signal Sa1 may be set to a frequency of 5 MHz to 15 MHz suitable for removal of biofilm.

The voltage drop unit 63 may be used to reduce the magnitude (eg, peak-to-peak voltage, etc.) of the first AC signal Sa1 output from the signal generator 62. For example, the voltage drop unit 63 may be implemented as a resistance element (R), through which the second AC signal (Sa2), whose size is reduced compared to the first AC signal (Sa1), is transmitted to the voltage drop unit 63. ) can be output from.

The filter 64 may perform a filtering operation on the second AC signal Sa2 supplied from the voltage drop unit 63. For example, the filter 64 may be set as a low pass filter including a capacitor element (C), and converts the second AC signal (Sa2) in the form of a sawtooth wave into a sine wave. It can be converted into a third AC signal (Sa3) in the form of.

Additionally, the precision of the driving signal Vd can be improved by removing the unexpected DC offset of the second AC signal Sa2 through the filter 64.

The offset adjuster 65 may generate the driving signal Vd by mixing the DC signal with the third AC signal Sa3 output from the filter 64. For example, the offset adjustment unit 65 may be configured to include a plurality of resistance elements (R1, R2) and may be adjusted to a specific voltage (e.g., the output voltage (Vo) of the DC-DC converter 61). A DC signal of a predetermined level can be generated by performing voltage division.

That is, the third AC signal (Sa3) supplied through the filter 64 is overlapped with the DC signal generated at the common node (N) of the first and second resistor elements (R1) and R2, resulting in a final driving signal. (Vd) can be generated.

In this case, the amplitude of the driving signal (Vd) may be set to 0.1mv to 10V, but is not limited thereto.
