[0002] Physical therapy is a crucial component of both modern and traditional medicine. It can be divided into two main categories: one primarily involves functional training and manual therapy, also known as exercise therapy or kinesiology; the other primarily involves various physical agents (sound, light, cold, heat, electricity, magnetism, water, etc.), also known as physiotherapy.

[0003] With the accelerating pace of life and increasing work pressure, physical therapy devices are no longer limited to medical purposes but are gradually expanding into daily life to relieve users' physical and mental fatigue and daily discomfort. However, existing physical therapy devices are limited by fixed design, and most are large and heavy, making them difficult to carry and use.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. A self-priming physiotherapy device according to the present invention mainly comprises an air bag, an outer cover, an inner chamber, a main control circuit board and a flexible circuit board, wherein the outer cover comprises a cover top plate and a cover side surround, the top surface of the cover top plate is connected to the bottom of the air bag, a plurality of vents communicating with the interior thereof are provided on the outer surface of the air bag, the top of the air bag is connected to the main control circuit board, the four sides of the cover top plate are embedded in the interior of the cover top opening, and the cover side surround extends downward to form a cover bottom opening; the inner chamber comprises a chamber side surround and a chamber top and a chamber bottom connected to the two ends thereof, the chamber top is sealedly connected to the bottom surface of the cover top plate, the chamber bottom is sealedly connected to the flexible bottom layer, the bottom surface of the flexible bottom layer is close to the plane where the cover bottom opening is located, the top surface of the flexible bottom layer contacts the bottom surface of the flexible circuit board, the flexible circuit board and the battery are all located in the indoor cavity of the inner chamber; a plurality of penetrating side air holes are opened on the chamber side surround, a penetrating suction hole is opened in the middle of the cover top plate, an outer partition cavity is sandwiched between the chamber side surround and the cover side surround, and the outer partition cavity is sequentially connected to the side air holes, the chamber The inner cavity and the air suction hole are connected to the interior of the airbag; the main control circuit board is respectively connected to the battery and the flexible circuit board; when in use, the user first takes the airbag, and then presses down the outer cover and the inner chamber until the flexible bottom layer contacts the part to be treated on the user's body, and then presses the airbag downward to make the flexible bottom layer close to the part to be treated, and the outer cover is sealed around the part to be treated. Subsequently, the airbag is deflated, and the gas in the airbag is squeezed out from the vent hole. Then the airbag is released, and the airbag automatically returns to its original shape under the action of the rebound force. During the rebound process, the airbag draws gas from the air suction hole, the inner cavity, the side vents, and the outer partition cavity in turn, so that the outer partition cavity is negatively pressurized, thereby adsorbing the therapeutic device on the user's body. Subsequently, the main control circuit board is started to provide power to the flexible circuit board, thereby starting the heat-generating, electricity-generating or magnetic-generating circuit on the flexible circuit board, and then providing heat, electrical stimulation or magnetism to the part to be treated to achieve a therapeutic effect. The advantages of this design are as follows: First point: When using this design, you only need to press it, which is very convenient to operate. Moreover, this design relies on the negative pressure generated by pressing for adsorption. It can not only be reused, but also will not contaminate the instrument due to sweat, which helps to ensure the cleanliness of the instrument. Second point: When in use, this design directly contacts the bottom surface of the flexible bottom layer with the part to be treated, and the top surface of the flexible bottom layer contacts the bottom surface of the flexible circuit board that generates the treatment function, so that the flexible circuit board is exactly opposite the part to be treated, thereby achieving point-to-point treatment. Compared with the regional treatment in the prior art (such as the portable thermal shoulder treatment device in the background art, which relies on the dressing placed in the bag to treat the shoulder, although the shoulder is smaller than other parts of the human body, this is still regional treatment, and it is difficult to achieve point-to-point treatment. It has low accuracy, is easy to reduce the treatment effect, and also wastes heat energy and dressing), this design not only has higher accuracy and better treatment effect, but also has higher cost performance. Third point: This design as a whole not only contains fewer parts, but also has a smaller size, making it very convenient to carry; Therefore, the present invention is not only simple and convenient, easy to carry and use, but also has high accuracy and better physical therapy effect.

[0018] 2. In the self-priming therapy device of the present invention, the diameter of the side circumference of the cover preferably increases gradually from the top opening to the bottom opening of the cover. This design not only facilitates sealed contact between the outer cover and the area to be treated, facilitating subsequent negative pressure adsorption, but also disperses the downward pressure to avoid discomfort to the user. On this basis, if an outer expansion ring is further preferably provided around the bottom opening of the cover, it is further conducive to subsequent negative pressure adsorption and has stronger stability. Therefore, the present invention not only has strong stability after adsorption, but also avoids operational discomfort.

[0019] 3. In a self-priming physiotherapy device of the present invention, a filling body is preferably further provided in the indoor cavity, the bottom of the filling body is in contact with the top surface of the flexible circuit board, the top of the filling body is in contact with the bottom of the battery, an inner partition cavity is formed between the side of the filling body and the side of the chamber, and the inner partition cavity belongs to the indoor cavity. When used, the filling body can, on the one hand, separate the battery from the flexible circuit board, preventing the heat, electrical stimulation or magnetic force generated by the flexible circuit board from damaging the battery. On the other hand, the filling body can press the flexible circuit board tightly against the flexible bottom layer, and then press it tightly against the skin of the area to be treated, so that the heat, electrical stimulation or magnetic field force generated by the flexible circuit board can directly reach the human body, ensuring the treatment effect. Therefore, the present invention is not only safer, but also has a higher degree of direct contact for treatment, and the treatment effect is also better.

[0020] 4. In a self-priming physiotherapy device of the present invention, the flexible circuit board is preferably a layered structure, including a heating layer and a pulse layer separated from each other, the heating layer is provided with a heating circuit for heating by power, the pulse layer is provided with a pulse circuit, a sheet metal is connected to the pulse circuit, the heating circuit and the pulse circuit are both connected to the main control circuit board, and the pulse layer is located between the heating layer and the flexible bottom layer. During application, after the main control circuit board is started, the main control circuit board provides power to the heating circuit and the pulse circuit respectively, so that the heating circuit generates heat and the pulse circuit generates electrical stimulation (after the circuit where the sheet metal is located is turned on, current is transmitted on the sheet metal, and contact with the sheet metal will cause electric shock, thereby generating electrical stimulation). At the same time, the heating layer and the pulse layer are separated from each other, the heating circuit and the pulse circuit do not interfere with each other, and both belong to flexible circuit boards, have strong deformation ability, are conducive to pressing against the flexible bottom layer, and thus press against the skin of the part to be treated, thereby improving the therapeutic effect. Therefore, the present invention can provide two therapeutic forces, heat and electrical stimulation, at the same time, and has a strong therapeutic effect.

[0021] 5. In a self-priming physiotherapy device of the present invention, a groove is preferably provided on the top of the airbag, and a main control circuit board and an operation panel are embedded and connected in the groove. The bottom surface of the main control circuit board contacts the bottom surface of the groove, the top surface of the main control circuit board contacts the bottom surface of the operation panel, and the top surface of the operation panel contacts the external environment, and the main control circuit board and the operation panel are connected by signal. When used, the operation panel can be either touch-sensitive or mechanical keyboard-sensitive. The operation panel can be operated to control the main control circuit board and to switch the flexible circuit board. It can even be further optimized with reference to similar prior art to adjust the size of the heat, electrical stimulation or magnetic force generated by the flexible circuit board, the ability to charge the battery, and the ability to remotely control the operation panel, etc. Therefore, the control mode of the present invention is diverse and the external expansion capability is relatively strong.
