Description

Electromagnetic radiation source for physiotherapy

Technical Field

The invention relates to the field of physical therapy, in particular to an electromagnetic radiation source for physical therapy.

Background

Physical therapy by using infrared radiation is a widely existing method for improving physical conditions and accelerating physical recovery. Among them, moxibustion, dragon moxibustion, indirect moxibustion and other various kinds of plant products using burning herbs, etc. the burned or heated plant products emit infrared radiation having a specific spectrum for physical therapy. These infrared radiation strikes the diseased area of the body and heats the epidermis and subcutaneous tissue of the affected area, slowing the disease and accelerating the recovery of internal muscles or other tissues. Typically, as in moxibustion, the infrared light after ignition produces two peaks, one at each of about 2um and 10um as shown in fig. 1a, i.e. the majority of the infrared radiation is concentrated in both regions. Other moxibustion varieties also have similar spectral distributions, simply because the burning material varies in specific wavelengths and energy distributions. However, radiation by combustion can cause problems such as environmental pollution from smoke, combustion that is not easily controlled by external ventilation, etc. There are also many infrared spectra that require combustion energy to produce, such as by electrically heating ceramic materials, similar to moxibustion. The Zhonglin spectrometer is heated to a sufficient temperature by a heater, the outside of the heater is a ceramic material layer, the surface of the ceramic material layer is coated with a special infrared spectrum conversion coating which is formed by mixing a large amount of metal oxide or chloride, the output spectrum after passing through the spectrum conversion layer is shown in figure 1b, and the spectrum also has two infrared energy peaks similar to moxibustion, but the specific energy distribution is slightly different. In addition to using a high temperature heater to heat a ceramic material layer to generate infrared radiation, philips also proposed an infrared lamp that generates broad-spectrum infrared radiation having a wavelength ranging from near infrared to far infrared, but provided with a special filter lens in front of the infrared lamp to allow only infrared waves of a desired wavelength band to radiate outward through the filter lens.

The prior art infrared radiation methods all have a significant disadvantage in that once the source of the infrared radiation is determined, the energy output in different bands of the infrared spectrum is not adjustable. The energy proportion of each wave band in the output wave spectrum is kept unchanged, and the whole radiation power can be changed only by changing the heating power or the using amount, but the whole radiation power needs to be increased for increasing the curative effect, which probably causes low-temperature scald. These sources of infrared radiation are subject to problems, either of insufficient radiation energy to be effective in treatment or of excessive radiation energy causing burns. Moreover, the curative effect of the infrared radiation on different parts of different people is different from person to person, the effect is obvious for some people, and the infrared radiation is completely ineffective for some people. The body condition of each person is different, the part of a patient is different, and the mechanism of the patient is different (muscle sprain, contusion, subcutaneous hemorrhage, inflammation and the like), so that different wavelengths are needed to realize the optimal treatment effect.

Therefore, it is necessary to develop an infrared light source capable of outputting effective infrared radiation with sufficient energy and preventing scald, so as to achieve more stable and reliable physiotherapy effect on different parts of more people.

The two infrared lights have different effects and therefore different optimal applications.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

The present invention provides an electromagnetic radiation therapy apparatus for use in therapy comprising a plurality of sources of electromagnetic radiation, typically two or more sources of infrared radiation having different spectral energy distributions, or a combination of sources of infrared and microwave radiation, whereby electromagnetic radiation energy having a complex frequency and spectral energy distribution is provided to an area of a human body in need of therapy. The structure and effect of the electric field radiation physiotherapy apparatus of the present invention will be described below by taking two infrared light sources as an example.

Referring to fig. 2, which is a schematic structural view of the electromagnetic radiation physiotherapy apparatus of the present invention, the electromagnetic radiation physiotherapy apparatus includes at least one main cabinet, the main cabinet includes a first infrared light source 10 and a second infrared light source 20, and a controller 30 is connected to the first infrared light source 10 and the second infrared light source 20 to control the output power ratio of the two infrared light sources, respectively. The first infrared light source 10 and the second infrared light source 20 respectively combine the output special infrared lights together through the respective infrared

optical fibers

11 and 12, and output the special infrared lights through a mixed optical fiber. In which a hybrid fiber is disposed in the arm 110, infrared light from two light sources is mixed and electromagnetic energy is radiated outward through the radiation head 120. The radiation head 120 is further provided with an irradiation cover 130 having an opening at the center and an inner wall surface made of a material reflecting infrared light, so that the mixed infrared light in the radiation head can pass through without loss. The outlet end aperture and shape of the irradiation cover 130 are adjustable, the aperture of the irradiation cover can be enlarged when the area of the region needing physical therapy is large, and the aperture of the outlet end of the irradiation cover 130 can be reduced when the area needs to be concentrated on a small region. The infrared radiation light passes through the irradiation cover and then irradiates on the human body area, and finally an irradiation area A is formed. In some applications, when the irradiation region a is non-circular, the corresponding optimal distribution of the radiation energy in space can also be obtained by adjusting the shape of the irradiation mask or replacing the irradiation mask with a suitable one.

The first infrared light source 10 outputs first infrared light having a spectral energy distribution profile as shown in fig. 4a, and the second infrared light source 20 outputs second infrared light having a second spectral energy distribution profile as shown in fig. 4 b. From the energy distribution curve S1 of the first infrared light, most of the energy of the first infrared light is concentrated in the wavelength band of 2-6um, especially 2-4um, and the infrared radiation of other wavelength bands is very low and can be substantially ignored. The first infrared light source 10 may be generated by laser light emitted from yttrium aluminum garnet, or may be a wide spectrum infrared light source passing through a special filter which allows only infrared light in the wavelength range of 2-4um or 2-6um to pass through.

From the second infrared light energy distribution curve S2, it can be seen that most of the energy of the second infrared light is concentrated in the wavelength band of 8-12um, especially in the wavelength band of 9-11um, and the infrared radiation of other wavelength bands is very low. The second infrared light source 20 may be made of carbon fiber, and is specifically a heating wire for applying a heating current to the carbon fiber, so that the carbon fiber emits infrared light with a corresponding spectrum energy distribution.

The first infrared light has a different effect from the second infrared light during the treatment, wherein the first infrared light has a shorter wavelength, i.e. a higher frequency and energy, so that it is able to penetrate the skin to reach deeper subcutaneous tissue. Since water has a strong absorption capacity for the infrared wavelengths 950-1700nm, the first infrared light can cross many tissues rich in water under the skin and directly act on the organic structures of each cell. And the wavelength generated in the vibration or distortion process of the carbon-carbon molecular bond is just about 3um of infrared wavelength in the C-C bond existing in the organic matter in the human tissue, so the spectrum of the first infrared light can just avoid the absorption interference of water in the tissue to the infrared radiation, and can drive the vibration of each molecule rich in the C-C piece in the tissue. The second infrared light has a longer wavelength and a lower frequency and energy and therefore acts more on the skin surface area, penetrating the heat transferred in the infrared radiation down or towards other parts of the body by heating the surface. Besides the widely existing C-C bonds, the human tissue also comprises a larger amount of C-H bonds, and the wavelength of infrared radiation emitted by the carbon-H bonds in the vibration or distortion process is exactly concentrated on about 10um, so the second infrared light can promote the vibration of the carbon-H bonds in the human tissue and improve the energy of the carbon-H bonds. The first infrared light and the second infrared light provided by the invention can provide energy for organic tissues in a body most efficiently, and the energy provided for the tissues can promote the autoimmune system of the human body or the body tissues to generate corresponding reactions, so that the recovery of the body tissues is accelerated. Meanwhile, the infrared radiation with a concentrated waveband provided by the invention has little other infrared radiation which only heats water or epidermis, so that the heating side effect on tissues is not obvious, and infrared light with enough power can be irradiated for a long time without worrying about low-temperature scald.

The two infrared lights have different effects and thus have different optimal applications, such as thin subcutaneous tissue in the region where physical therapy is required, for example, in the neck, joints of bones, or affected parts causing pain near the epidermis, so that the second infrared light with higher power can be used while the first infrared light with lower power is outputted. As shown in fig. 5, a combination of S1a and S2a is applicable to this case. In contrast, when the subcutaneous tissue is thicker in the area to be treated and the infrared light with stronger penetrating power is needed, the first infrared light with stronger power and the second infrared light with lower power can be selected, as shown in fig. 5, the output power of S1b is much larger than that of S2 b. The spectral energy distributions of the first and second infrared light in fig. 4 and 5 above are merely exemplary, and the actual spectral energy distribution may be influenced by the light source material, and different electromagnetic radiation materials may be selected to produce radiation having different spectral energy distributions. However, the choice of infrared source still requires ensuring that the energy of the two infrared sources is concentrated in the 2-4um and 8-12um bands, and more than 50% of the external radiation generated by the source particularly applicable to the present invention needs to be concentrated in these two bands, and most preferably more than 70% of the energy needs to be concentrated in these bands. Other bands of infrared radiation only heat the water more or the epidermis has less effect on the recovery of the body, but is easy to cause overheating and scalding, so the proportion of the radiation energy in each infrared light source must be controlled to be low, such as less than 30%.

Referring to fig. 3, a second embodiment of the electromagnetic radiation source for physical therapy according to the present invention is shown, which comprises a first radiation source 210 and a second radiation source 220, wherein the first and second radiation sources have inclination angles close to each other so that both generate light beams to irradiate the same body irradiation area a, and a controller 30 for controlling the power output ratio of the two radiation sources. The device also comprises a detector 40, wherein the detector 40 faces the irradiation area A, the detector can be used for detecting the temperature of the skin on the surface of the body, and when the skin temperature is detected to exceed a set value, such as 43 degrees, the output power of the two radiation sources is automatically reduced, or the output power of one radiation source is reduced, so that the power irradiated to the skin is greatly reduced, and low-temperature scald is avoided. Or the detector 40 may further integrate a distance probe for detecting the distance between the electromagnetic radiation source and the irradiation area a, and the average power reaching the surface of the irradiation area a may be calculated according to the obtained distance parameter and the output powers of the first and second radiation sources. In practical clinical application, the distance between the light source and the irradiation area directly influences the area size of the irradiation area A, namely the size of a light spot, so that the distance parameter influences the unit area power reaching the irradiation area under the condition of fixed output power, the output radiation power can be automatically corrected according to the distance parameter after the distance probe is added, and the deviation of the actual radiation power caused by personal factors is avoided.

In addition to the distance parameter, the diameter and shape of the opening of the irradiation cover 130 also affect the average power per unit area in the irradiation region a, so the controller 30 can automatically calculate according to the distance parameter and the parameters such as the caliber of the irradiation cover 130, and adjust the output power of the first and second radiation sources, respectively, so that the radiation power finally reaching the irradiation region a has sufficient power per unit area, and low-temperature scald caused by overheating cannot be caused.

Besides the infrared light, the first and second radiation sources in the present invention may also be microwave radiation sources, or a third radiation source is additionally provided on the basis of the original two infrared radiation sources. The radiation wavelength of the microwave radiation source is not related to the energy of C-C, C-H bonds in body tissues, but the radiation penetrating capability is strong, the body tissues in deeper regions can be heated, and when the infrared light source is matched with the infrared light source to irradiate the same irradiation region of a human body together, the blood flow in the region can be promoted, the activities of organic tissues and various enzymes are increased, and the soreness of muscles and tendons caused by various reasons of different regions of the body is comprehensively improved.

The controller 30 according to the present invention may be used to control the electrical power input to the first and second radiation sources, thereby controlling the output radiation power of both radiation sources. Or the controller can respectively output two independent control signals to the two radiation sources, and the two radiation sources output corresponding radiation power to the external body area according to the instruction of the received control signals. The control signal may be an average power output by the two radiation sources, or may be a pulse signal, and at least one of the two radiation sources outputs a pulse-shaped radiation power, that is, the output power directly and continuously changes in a high-low state. The controller can also realize the adjustment of the radiation output power of each radiation source by setting the duty ratio of the pulse signal.

The controller may store preset treatment programs for treating different parts and different diseases of the body, and the programs can control the output radiation power of a plurality of radiation sources in one treatment period, the output radiation power of the plurality of radiation sources in the whole treatment period, and the like. The user can select the corresponding program according to the requirement to automatically execute the treatment program in use. The parameters can be preset, or can be manually set by a user or a rehabilitation doctor according to the field condition, and the controller automatically executes the required treatment process according to the preset or manually set parameters.

The foregoing is only a preferred embodiment of the present invention, and although the present invention has been disclosed in the preferred embodiments, it is not intended to limit the present invention. Those skilled in the art can make numerous possible variations and modifications to the present teachings, or modify equivalent embodiments to equivalent variations, without departing from the scope of the present teachings, using the methods and techniques disclosed above. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention, unless the contents of the technical solution of the present invention are departed.
