[0002] With social development, there are more and more physiotherapy products on the market, including physiotherapy electrode pads. The principle of using physiotherapy electrode pads is to fix the electrode pads to the corresponding physiotherapy area of ​​the patient, and then power the physiotherapy electrode pads, transmitting current pulse signals from a low-frequency physiotherapy device to the patient's physiotherapy area, simulating the effects of acupuncture, massage, manipulation, and percussion, thereby achieving therapeutic and health care effects, avoiding the pain and blood cross-infection problems caused by traditional acupuncture.

[0003] Currently, existing physiotherapy electrode pads are prone to loosening during use, resulting in inadequate contact between the electrode pad layer and the patient's skin. This causes overheating at the contact site, leading to stinging or blisters, which not only affects the treatment effect but also causes significant pain for the patient. Therefore, there is a need to design an anti-loosening physiotherapy electrode pad to solve the problems mentioned above.

[0004] In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figure 1-3 As shown, this embodiment provides a physiotherapy electrode pad with anti-loosening effect, including: a connecting piece 1, a physiotherapy electrode pad body 2 disposed on the lower side of the connecting piece 1, a flexible connecting rod 3 disposed at each corner of the connecting piece 1, and an adsorption component 4 disposed on the lower side of the flexible connecting rod 3.

[0031] A connecting pipe 5 is provided on one side of the adsorption component 4. One end of the multiple connecting pipes 5 is connected to a suction pipe 6, and one end of the suction pipe 6 is connected to a suction device 7.

[0032] A fixing component is provided on the connecting piece 1;

[0033] The adsorption assembly 4 includes a ball head assembly and a suction cup 8. The ball head assembly includes a spherical groove formed on the lower side of the flexible connecting rod 3, a ball head that is movably fitted in the spherical groove, and a rod body 9 set on one side of the ball head. The suction cup 8 is fixedly connected to the rod body 9.

[0034] The air extraction device 7 includes an air extraction cylinder 10. One end of the air extraction cylinder 10 is provided with a fixing plate, and a connecting pipe 12 is provided on the fixing plate. The other end of the air extraction cylinder 10 is threaded with a limit cap 13. An opening 14 is provided on one side of the limit cap 13. At least one sealing plate 15 is elastically fitted inside the air extraction cylinder 10. A push rod 16 is connected to one side of the sealing plate 15. The push rod 16 is slidably fitted inside the opening 14.

[0035] The sealing plate 15 is a circular plate, and an annular groove 17 is provided on the periphery of the circular plate, and a sealing ring 18 is provided in the annular groove 17.

[0036] A spring 19 is provided between the sealing plate 15 and the fixing plate;

[0037] Grooves 20 are provided on both sides of the opening 14, and blocks 21 are installed on both sides of the push rod 16.

[0038] The fixing components include a male hook and loop fastener and a female hook and loop fastener disposed on the connecting piece 1. The male hook and loop fastener and the female hook and loop fastener are positioned correspondingly and are detachably connected.

[0039] Each of the multiple connecting pipes 5 and the exhaust pipe 6 is equipped with a connector, which is connected to the corresponding connecting pipe 5 and exhaust pipe 6 respectively.

[0040] One application of this embodiment is as follows: The physiotherapy electrode pad body 2 is fixed to the lower surface of the connecting piece 1 by pasting or snapping. The flexible connecting rod 3 is integrally molded from medical-grade silicone material at the four corners of the connecting piece 1. A ball head is movably embedded in the spherical groove at its lower end. The lower end of the rod body 9 fixed to one side of the ball head is perpendicularly connected to the center of the suction cup 8. One end of the suction cylinder 10 of the suction device 7 is connected to the suction pipe 6 through the connecting pipe 12 on the fixed plate, and the other end is detachably connected to the limiting cap 13 through threads. The grooves 20 on both sides of the opening 14 of the limiting cap 13 and the locking blocks 21 on both sides of the push rod 16 form a sliding limiting fit. The spring 19 maintains a distance of 2-3 cm between the sealing plate 15 and the fixed plate in its natural state.

[0041] The specific negative pressure adsorption operation procedure is as follows:

[0042] 1. Pre-fitting and positioning: Align the physiotherapy electrode pad body 2 with the physiotherapy area, so that the suction cup 8 initially contacts the skin surface. The ball head assembly allows the rod body 9 to automatically adjust the angle according to the skin curvature, with a maximum tilt angle of ±45°, ensuring that the edge of the suction cup 8 is completely in contact with the skin.

[0043] 2. During manual air extraction, push rod 16 is pushed axially along the air extraction cylinder 10. Locking block 21 slides along groove 20, causing sealing plate 15 to move towards the fixed plate. Sealing ring 18, made of nitrile rubber with a Shore hardness of 60±5A, fits tightly against the inner wall of air extraction cylinder 10, expelling air between the fixed plate and sealing plate 15. Simultaneously, spring 19 is compressed to its maximum stroke compression of 15-20mm. When sealing plate 15 is fully against the fixed plate, push rod 16 is rotated 90°, and locking block 21 enters the annular limiting area of ​​limiting cap 13. Circumferential locking is achieved through the limiting boss at the end of groove 20, preventing spring 19 from rebounding.

[0044] 3. Negative Pressure Formation and Adsorption: Rotating the push rod 16 counterclockwise aligns the locking block 21 with the groove 20. After releasing the limit, the spring 19 resets, causing the sealing plate 15 to move in the opposite direction, creating negative pressure within the suction cylinder 10. This negative pressure acts synchronously on each connecting pipe 5 through the suction pipe 6 and the three-way connector, drawing out the air between the suction cup 8 and the skin, forming a negative pressure adsorption force of 0.8-0.9 standard atmospheres. The omnidirectional movement of the ball head assembly ensures that each suction cup 8 independently adapts to the skin's curvature, avoiding air leakage caused by local undulations.

[0045] After suction cup 8 completes negative pressure adsorption, the male and female sides of the Velcro on connecting piece 1 are attached around the treatment area to form a mechanical fixation layer. The effective contact area of ​​the Velcro is no less than 60% of the surface area of ​​connecting piece 1. Combined with the negative pressure adsorption of the four corner suction cups, a composite anti-loosening structure of "point adsorption + surface fixation" is achieved. For sports scenarios, the replaceable connecting tube 5 can be a medical-grade elastic flexible tube with an inner diameter of 3-5mm, and an external small electric air pump can be used for existing technology adaptation. The system enhances adsorption stability by maintaining continuous negative pressure.

[0046] Disassembly and Reset: Unscrew the limit cap 13 counterclockwise, manually pull the push rod 16 to reset the sealing plate 15. The micro vent holes with a diameter of 0.5mm are provided on the edge of the suction cup 8. These holes, not shown in the figure, automatically balance the internal and external air pressure during disassembly to prevent skin injury from violent tearing. It should be noted that all electrical devices involved in this application can be powered by a battery or an external power source.

[0047] This invention features a flexible connecting rod 3 and an adsorption component 4 at the corner of the connecting piece 1, which utilizes a vacuum device 7 to create negative pressure adsorption. Combined with the ball head component, it achieves adaptive fit to different skin surfaces. At the same time, the fixing component further enhances the fixing effect, effectively solving the problem of loosening of the physiotherapy electrode pads during use, and improving the physiotherapy effect and user experience.
