Description

Technical Field

[0001] This utility model relates to a physiotherapy instrument, belonging to the field of physiotherapy, and particularly to a self-priming physiotherapy instrument. Background Technology

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

[0003] With the fast pace of life and increasing work pressure, physiotherapy 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 physiotherapy devices are limited by their fixed design, and most are large and heavy, increasing the difficulty of carrying and using them.

[0004] Chinese patent application No. 201610610363.6, filed on July 29, 2016, discloses a portable thermal shoulder physiotherapy device, comprising an outer cover, a heating pad, a thermal sensor, a placement bag, and a controller. The outer cover includes an arm area, a shoulder area, and a circular chest strap. Connectors are provided on both sides of the arm area. The arm area is used for application around the upper arm; the shoulder area is used for application to the shoulder; the chest strap is used to wrap around the patient's chest; a placement bag is provided on the inner wall of the outer cover; the heating pad is fixed to the inner wall of the outer cover at a position corresponding to the placement bag; the thermal sensor is located inside the placement bag; the outer cover and the controller are independent of each other; the thermal sensor and the heating pad are electrically connected to the controller via pluggable wires. Although this design can be applied to the shoulder for physiotherapy, it still has the following drawbacks:

[0005] First, this design requires the coordinated use of multiple components, such as the arm area, shoulder area, chest strap, and connectors, to fix the physiotherapy device, making the structure complex and the operation inconvenient.

[0006] Secondly, in addition to the outer cover, the design requires an external controller and battery when in use, making the overall structure inconvenient and increasing the difficulty of carrying it.

[0007] The information disclosed in this background section is intended only to enhance understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0013] The diameter of the side circumference of the cover gradually increases from the top opening to the bottom opening of the cover.

[0014] An outer expansion ring is fitted around the bottom opening of the cover.

[0015] A through-hole is provided in the middle of the top cover plate, through which wires between the main control circuit board and the battery, as well as between the main control circuit board and the flexible circuit board, pass.

[0016] The bottom of the airbag has a bottom opening that is directly connected to the top surface of the cover plate, and the top of the chamber has a top opening that is directly connected to the bottom surface of the cover plate. The interior of the airbag is connected to the inner cavity of the chamber after passing through the bottom opening, the air inlet, and the top opening in sequence.

[0017] A bottom opening is provided in the middle of the bottom of the chamber, and a flexible circuit board is embedded in the bottom opening. The area of ​​the bottom opening is smaller than the area of ​​the flexible bottom layer.

[0018] The inner cavity is also provided with a filler, the bottom of which is in contact with the top surface of the flexible circuit board, the top of which is in contact with the bottom of the battery, and an inner spacer cavity is formed between the side wall of the filler and the side wall of the chamber.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model discloses a self-aspirating physiotherapy device, mainly comprising an airbag, an outer cover, an inner chamber, a main control circuit board, and a flexible circuit board. The outer cover includes a top plate and side panels. The top surface of the top plate is connected to the bottom of the airbag. Multiple ventilation holes communicating with the interior of the airbag are provided on its outer surface. The top of the airbag is connected to the main control circuit board. The four sides of the top plate are embedded and connected to the interior of the top opening. The side panels extend downwards to form a bottom opening. The inner chamber includes side panels and a top and bottom connected to its two ends. The top of the chamber is sealed to the bottom surface of the top plate, and the bottom is sealed to the flexible bottom layer. The bottom surface of the flexible bottom layer is close to the plane where the 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 battery are located within the inner cavity of the inner chamber. Multiple through-hole side air holes are provided on the side panels, and a through-hole suction hole is provided in the middle of the top plate. An outer spacer cavity is formed between the side panels and the outer cover side panels. This outer spacer cavity is connected sequentially through the side air holes... The inner chamber and air inlet are connected to the inside of the airbag. The main control circuit board is electrically connected to the battery and flexible circuit board respectively. In use, the user first takes the airbag, then presses down the outer cover and inner chamber together until the flexible bottom layer contacts the area to be treated on the user's body. Then, the user presses down on the airbag to make the flexible bottom layer adhere tightly to the area to be treated, and the outer cover seals the area around the area to be treated. The airbag is then deflated, and the gas inside is squeezed out through the vent. Releasing the airbag causes it to automatically return to its original shape under the action of rebound force. During this rebound process, the airbag sequentially draws gas from the air inlet, inner chamber, side vent, and outer septum, creating a negative pressure in the outer septum, thus adhering the physiotherapy device to the user's body. Then, the main control circuit board is activated to provide power to the flexible circuit board, thereby activating the heat-generating, electricity-generating, or magnetization circuits on the flexible circuit board, which in turn provide heat, electrical stimulation, or magnetic force to the area to be treated, achieving a therapeutic effect. The advantages of this design are as follows:

[0024] Firstly, this design is very convenient to use; simply press it. Moreover, the design relies on the negative pressure generated after pressing for adsorption, which not only allows for repeated use but also prevents the instrument from being contaminated by sweat, thus ensuring the cleanliness of the instrument.

[0025] Secondly, in use, this design directly contacts the bottom surface of the flexible substrate with the area to be treated, while the top surface of the flexible substrate contacts the bottom surface of the flexible circuit board that generates the therapeutic function. This ensures that the flexible circuit board and the area to be treated are perfectly aligned, thus achieving point-to-point therapy. Compared with existing regional therapy technologies (such as the portable thermal shoulder therapy device in the background technology, which relies on dressings placed in a bag to treat the shoulder, although the shoulder is relatively small compared to other parts of the body, this is still a regional therapy, which is difficult to achieve point-to-point therapy, has low precision, easily reduces the therapeutic effect, and wastes heat energy and dressings), this design not only has higher precision and better therapeutic effect, but also has a higher cost-effectiveness.

[0026] Thirdly, this design not only contains fewer parts but is also smaller in size, making it very convenient to carry.

[0027] Therefore, this invention is not only simple and easy to carry and use, but also highly accurate and has a better therapeutic effect.

[0028] 2. In this self-suction physiotherapy device, the diameter of the side circumference of the cover preferably gradually increases from the top opening to the bottom opening. This design not only facilitates a sealed contact between the outer cover and the area to be treated, promoting subsequent negative pressure adsorption, but also disperses the downward pressure, preventing discomfort to the user. Furthermore, if an outer expansion ring is preferably provided around the bottom opening of the cover, it further enhances subsequent negative pressure adsorption and provides stronger stability. Therefore, this device not only offers strong adhesion after adsorption but also avoids operational discomfort.

[0029] 3. In this self-priming physiotherapy device, preferably, a filler is also provided in the inner cavity. The bottom of the filler contacts the top surface of the flexible circuit board, and the top of the filler contacts the bottom of the battery. An inner partition cavity is formed between the sidewall of the filler and the sidewall of the chamber, and this inner partition cavity is part of the inner cavity. During application, the filler can, on the one hand, separate the battery from the flexible circuit board, preventing damage to the battery from the heat, electrical stimulation, or magnetic force generated by the flexible circuit board. On the other hand, the filler can firmly press the flexible circuit board against the flexible substrate, and then firmly against the skin of the area to be treated, allowing the heat, electrical stimulation, or magnetic force generated by the flexible circuit board to directly reach the human body, ensuring the therapeutic effect. Therefore, this invention not only has high safety but also a high degree of direct contact in physiotherapy, resulting in better therapeutic effects.

[0030] 4. In this self-aspirating physiotherapy device, the flexible circuit board preferably has a layered structure, including a heating layer and a pulse layer separated from each other. The heating layer is equipped with a heating circuit that generates heat, and the pulse layer is equipped with a pulse circuit. A sheet of metal is connected to the pulse circuit. Both the heating circuit and the pulse circuit are electrically connected to the main control circuit board. The pulse layer is located between the heating layer and the flexible bottom layer. In application, when the main control circuit board is activated, it provides power to both the heating circuit and the pulse circuit, causing the heating circuit to generate heat and the pulse circuit to generate electrical stimulation (after the circuit containing the sheet of metal is turned on, current is transmitted through the sheet of metal; contact with the sheet of metal will result in an electric shock, thus generating electrical stimulation). Simultaneously, the heating layer and the pulse layer are separated, and the heating circuit and pulse circuit do not interfere with each other. Both are flexible circuit boards with strong deformation capabilities, which facilitates close contact with the flexible bottom layer and thus with the skin of the area to be treated, enhancing the therapeutic effect. Therefore, this invention can simultaneously provide both thermal and electrical stimulation for physiotherapy, resulting in a strong therapeutic effect.

[0031] 5. In this self-aspirating physiotherapy device, a groove is preferably formed at the top of the airbag. A main control circuit board and an operation panel are embedded and connected within this groove. The bottom surface of the main control circuit board contacts the bottom surface of the groove, and the top surface of the main control circuit board contacts the bottom surface of the operation panel. The top surface of the operation panel is in contact with the external environment, and the main control circuit board and the operation panel are connected by a signal connection. In application, the operation panel can be either touch-sensitive or a mechanical keyboard type. Operating the operation panel controls the main control circuit board, switches the flexible circuit board, and can even be further optimized, similar to existing technologies, to control the magnitude of 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, this invention offers diverse control methods and strong external expansion capabilities.

[0065] Example 1:

[0066] See Figure 1 — Figure 11 A self-priming physiotherapy device includes an airbag 4, an outer cover 5, and an inner chamber 6. The outer cover 5 includes a top plate 51 and side panels 52. The top surface of the top plate 51 is connected to the bottom of the airbag 4. Multiple ventilation holes 43 communicating with the interior of the airbag 4 are provided on the outer surface of the airbag 4. The top of the airbag 4 is connected to a main control circuit board 2. The four sides of the top plate 51 are connected to the top opening 53 of the top of the side panels 52. The side panels 52 extend downwards to form a bottom opening 54, and an inner chamber 6 is provided inside the side panels 52. The inner chamber 6 includes a chamber side panel 62 and a chamber top 61 and a chamber bottom 63 connected to its two ends. The chamber top 61 is sealed to the bottom surface of the top plate 51, and the chamber bottom 63 is sealed to the bottom surface of the top plate 51. The flexible bottom layer 7 is sealed and connected. The bottom surface of the flexible bottom layer 7 is close to the plane where the bottom opening 54 of the cover is located (preferably, the bottom surface of the flexible bottom layer 7 coincides with the plane where the bottom opening 54 of the cover is located). The top surface of the flexible bottom layer 7 is in contact with the bottom surface of the flexible circuit board 3. The flexible circuit board 3 and the battery 8 are both located in the inner cavity 64 of the inner chamber 6. The side wall 62 of the chamber is provided with a plurality of through side air holes 65. The top plate 51 is provided with a through air intake hole 55 in the middle. The side wall 62 of the chamber and the side wall 52 of the cover form an outer partition cavity 56.

[0067] When using this self-priming physiotherapy device, first take out the device, such as by pinching the airbag 4 or the outer cover 5. Then, press the outer cover 5 against the area to be treated until the flexible bottom layer 7 contacts the area. Next, press down firmly on the outer cover 5 and the airbag 4 until the airbag 4 is compressed. Then, release the airbag 4 so that it automatically returns to its original shape under the action of the rebound force. During this rebound process, the airbag 4 draws gas from the suction hole 55, the inner cavity 64, the side air hole 65, and the outer septum 56 in sequence, so that the outer septum 56 is under negative pressure, thereby adhering the physiotherapy device to the user's body. Then, turn on the main control circuit board 2 to provide power to the flexible circuit board 3, thereby activating the heat-generating, electricity-generating, or magnetization circuits on the flexible circuit board 3, and thus providing heat, electrical stimulation, or magnetic force to the area to be treated to achieve the physiotherapy effect.

[0068] Example 2:

[0069] The basic content is the same as in Example 1, except that:

[0070] The top cover 51 has a through wiring hole 57 in the middle, through which the wires between the main control circuit board 2 and the battery 8, as well as the wires between the main control circuit board 2 and the flexible circuit board 3, pass.

[0071] In application, there will be wires for electrical connection between the main control circuit board 2 and the battery 8, as well as between the main control circuit board 2 and the flexible circuit board 3. In this case, it is preferable for the wires to pass through the wiring hole 57, which can both realize the wiring and avoid the wires from getting tangled.

[0072] Example 3:

[0073] The basic content is the same as in Example 1, except that:

[0074] The inner cavity 64 is also provided with a filler 9. The bottom of the filler 9 is in contact with the top surface of the flexible circuit board 3, and the top of the filler 9 is in contact with the bottom of the battery 8. An inner spacer 66 is formed between the side wall of the filler 9 and the side wall 62 of the chamber. The inner spacer 66 belongs to the inner cavity 64.

[0075] In application, the filler 9 is located in the inner cavity 64. The bottom of the filler 9 can tightly press the flexible circuit board 3 against the flexible bottom layer 7, thereby pressing the flexible bottom layer 7 tightly against the skin of the area to be treated. This allows the heat, electrical stimulation or magnetic field force generated by the flexible circuit board 3 to directly reach the human body, ensuring the therapeutic effect. In addition, an inner partition cavity 66 is formed between the filler 9 and the side wall 62. This inner partition cavity 66 can be used for gas flow and for the routing of wires. Wires can also pass through the filler 9 for routing.

[0076] Example 4:

[0077] The basic content is the same as in Example 1, except that:

[0078] The flexible circuit board 3 has a layered structure, including a heating layer 31 and a pulse layer 32 that are separated from each other. The heating layer 31 is provided with a heating circuit 33 that generates heat when energized. The pulse layer 32 is provided with a pulse circuit 34. A sheet of metal 341 (which can be a closed metal sheet, or a perforated or mesh-like metal sheet) is connected to the pulse circuit 34. The heating circuit 33 and the pulse circuit 34 are both connected to the main control circuit board 2. The pulse layer 32 is located between the heating layer 31 and the flexible bottom layer 7.

[0079] The arrangement of the heating layer 31 and pulse layer 32 in this utility model can be referenced from the surface circuit layer 3 and bottom circuit layer 5 in patent application number 202421066137.2 (titled "A Flexible Circuit Board"). The heating circuit 33 is similar to the resistance wire 33 in that patent application, and the sheet metal 341 is similar to the copper sheet 52 in that patent application. In application, the surface circuit layer 3 and bottom circuit layer 5 are separated by the FPC matrix layer 4 and do not interfere with each other. When the resistance wire 33 in the surface circuit layer 3 is energized, it generates heat. When the copper sheet 52 is energized, the current transmitted on it will generate electrical stimulation to the nearby skin. Furthermore, if the current flowing through the copper sheet 52 is intermittently controlled, a regular, intermittent current stimulation can be felt, thus producing a pulse effect.

[0080] Example 5:

[0081] The basic content is the same as in Example 4, except that:

[0082] Please see Figure 9 , Figure 10 and Figure 11 The flexible bottom layer 7 has a conductive TPU 71 embedded in its center. The inner side of the conductive TPU 71 is in contact with the sheet metal 341, and the outer side of the conductive TPU 71 is in contact with the external environment.

[0083] When applied, the sheet metal 341 will have current flowing through it after being energized. Since the sheet metal 341 is in contact with the conductive TPU 71, current will also flow through the conductive TPU 71. At this time, the skin in contact with the outer surface of the conductive TPU 71 will be electrically stimulated.

[0084] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
