Abstract
Description
Technical Field
[0001] The present invention is a physical therapy device that combines the dual-mode effects of millimeter wave radiation and far-infrared irradiation, and belongs to the spectrum physical therapy device technology with dual-spectrum effects. Background Art
[0002] The millimeter wave technology used here comes from a small millimeter wave detector technology. The millimeter wave detector has the characteristics of extremely high frequency, strong directivity, low radiation intensity, good high temperature resistance, strong environmental adaptability, compact structure, small size, easy operation and use, and long life.
[0003] At present, there are many well-known millimeter wave therapeutic devices, which have been widely used in various large and medium-sized medical institutions such as hospitals and nursing centers. It mainly uses millimeter wave radiation to improve the activity of human cell molecules, promote cell division, improve the body's metabolic function, and achieve the effects of relaxing muscles and tendons, promoting blood circulation and removing blood stasis, and relieving pain. However, the existing millimeter wave therapeutic devices generally have a single mode of action, the patient experience is not obvious, and the size is large, which is not convenient for daily use at home.
[0004] The application of far-infrared therapy devices in the medical field has also been very extensive, mainly using their warming effect and penetration effect to achieve rehabilitation treatment of the patient's body functions. However, most of the existing far-infrared therapy devices currently use electric heating elements as far-infrared sources, which are generally large in size and power, and more or less have some safety hazards, making them not very convenient for home use; in addition, most of the existing far-infrared therapy devices are diffuse irradiation, which is not directional, and will also cause pollution and impact on the surrounding tissues and environment when used for local or acupoint irradiation.
[0005] In summary, the present invention adopts a mature small millimeter wave detector technology that has been widely used in the military field, and utilizes the stable extremely high frequency oscillation characteristics, suitable radiation intensity, good directionality, small size, and easy operation and use of this technology. At the same time, the heat energy generated during its working process is combined with the far-infrared radiation with a certain directionality formed by specific technical means to act on the patient's local area. When irradiating and treating the patient's lesion or acupoints, it can effectively improve the patient's experience and comfort; second, it can ensure that only the patient's lesion or acupoint is reliably irradiated without causing unnecessary effects on the surrounding tissues or environment; third, the physiotherapy instrument has a compact structure and a small size, and can be used in conjunction with various household daily necessities such as pillows and pads, which is very suitable for home care and health physiotherapy. The simultaneous use of millimeter wave radiation and far-infrared irradiation combines the penetration effect of millimeter wave radiation with the warming effect of far-infrared rays, just like combining acupuncture and moxibustion in traditional Chinese medicine. The two complement each other and can greatly improve its physiotherapy effect. Summary of the invention
[0006] In view of the deficiency of the existing millimeter wave therapy device technology in terms of a single working mode, the present invention provides a small-scale comprehensive physiotherapy device which integrates both millimeter wave radiation and far-infrared irradiation modes. The millimeter wave radiation and far-infrared irradiation are combined to complement and promote each other, thereby effectively improving and enhancing the physiotherapy effect, patient experience, and ease of use.
[0007] In view of the shortcomings of existing millimeter wave therapeutic device technology, such as large size, difficult operation and use, and inconvenient use for home care, the present invention adopts a millimeter wave oscillation and radiator technology with a compact structure and small size, so that it can be conveniently used in combination with daily household items such as pillows and cushions, while ensuring the safety and reliability of use, it also increases the convenience of use.
[0008] In view of the shortcomings of existing far-infrared therapy devices, such as large size, difficult to control irradiation intensity, and wide irradiation scattering area, no special electric heating elements are used here to generate far-infrared radiation. Instead, the heat energy generated during the millimeter wave oscillation and radiation process is used as the heat source for far-infrared irradiation. At the same time, through the use of thermal insulation layer sealing technology, most of the heat is sealed inside the metal energy focusing cover, and its main far-infrared rays are guided to concentrate on the area with the same direction of millimeter wave radiation, so that the far-infrared irradiation also has good directionality.

[0012] Figure 3 It is a summary of the specification in the present invention. DETAILED DESCRIPTION
[0013] In order to achieve the above object, the present invention is implemented in the following ways: 1. As Figure 1 As shown, one end of the GaAs diode ① is connected to the external power supply through the bias capacitor ④, and the other end of the GaAs diode ① is connected to the waveguide cavity ③ through the GaAs diode holder ②. The two are connected in a spiral manner, which, on the one hand, ensures the connection reliability, and on the other hand, can be used to adjust the relative position between the GaAs diode and the waveguide cavity to achieve the best coupling effect and realize efficient and stable ultra-high frequency millimeter wave oscillation. 2. The millimeter wave oscillation generated by the millimeter wave oscillator mainly exists in the form of surface waves on the inner surface of the waveguide cavity of the millimeter wave oscillator. Figure 2 The light is converted into space waves by the horn antenna ⑨ and radiated in a solid angle of about 30° in front of it, forming a basic millimeter wave oscillation and radiator system. 3. Such as Figure 1As shown, in order to detect whether the millimeter wave radiator is working properly, a mixing detection system consisting of a mixing tube ⑤ with extremely high frequency characteristics, a mixing tube socket ⑥, a detection capacitor ⑦, and a detection resistor ⑧ is designed here to detect the performance of the millimeter wave oscillation and radiator by using the Doppler effect generated when objects approach each other. One end of the mixing tube ⑤ is connected to the waveguide through the mixing tube socket ⑥, and the other end outputs the mixing detection signal through the detection capacitor ⑦ and the detection resistor ⑧. When the signal radiated by the millimeter wave oscillator encounters a moving object, it is reflected and fed back to the millimeter wave oscillator. The reflected signal is mixed with the millimeter wave oscillation and the oscillation signal of the radiator itself, thereby generating an envelope modulation signal, namely the Doppler signal, whose frequency is: f d =2v / λ; Among them, f d is the Doppler frequency, v is the approach speed between the object and the millimeter wave oscillator, and λ is the working wavelength of the millimeter wave oscillator. If the working wavelength of the millimeter wave oscillator λ=0.01m, and the approach speed between the external object and the millimeter wave oscillator is v=1m / s, then the Doppler signal frequency detected at this time is: f d =2v / λ=2*1 / 0.01=200Hz The approaching object here can be a metal plate or a human body, such as an iron plate, a palm, etc., but cannot be plastic or other non-metallic material objects. 4. Such as Figure 3 As shown, while realizing basic millimeter-wave oscillation and radiation, a cylindrical (or conical) metal energy focusing cover ⑩ is designed here to serve as the terminal cutoff and reflection system of the millimeter-wave oscillator, which together with the above-mentioned millimeter-wave oscillation and radiation system constitutes a complete millimeter-wave oscillation and radiator system. 5. As Figure 3 As shown, the cylindrical (or conical) metal energy-gathering cover ⑩ here shields the electromagnetic wave leakage during the millimeter wave oscillation and radiation process inside it, avoiding the impact on the surrounding environment. 6. When the millimeter wave oscillates and radiates, some energy loss is also generated. This part of the energy loss is converted into heat energy. This part of the heat energy and the three-terminal regulator The heat energy generated during the working process is absorbed by the cylindrical (or conical) metal energy collecting cover ⑩ and converted into far-infrared radiation to radiate outward. The far-infrared radiation direction generated by the inner surface is basically consistent with the millimeter wave radiation direction, while the far-infrared radiation generated by the outer surface is affected by the heat insulation layer. And non-metallic material housing Due to the limitation of the cylindrical (or conical) metal energy-gathering cover (10), on the one hand, the far-infrared radiation intensity generated by the inner surface is enhanced, while at the same time, the impact of its external leakage on the surrounding tissues and environment is reduced. 7. In order to ensure that the millimeter wave radiator is not contaminated or damaged, a non-metallic dust cover is designed at the front end of the millimeter wave radiator. The dust cover can be transparent or translucent. 8. In order to ensure the normal and effective millimeter wave oscillation and radiation, and to be used in conjunction with daily household items such as pillows and pads, other control systems other than the millimeter wave oscillation and radiation system are designed separately, so that the millimeter wave radiation and far-infrared irradiator is compact in size and can be conveniently used in conjunction with daily household items such as pillows and pads, making it easy to use and operate.
