[0023] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the patellar repositioning assistive device proposed in this invention includes a massage ring 1 and a fixing strap 2. The fixing strap 2 is connected to both ends of the massage ring 1 and is used to fix the massage ring 1 around the patella. The massage ring 1 includes a pneumatic massage unit 11, an infrared emitting unit 12, and a processing unit 13. Multiple pneumatic massage units and multiple infrared emitting units are alternately distributed in the inner ring of the massage ring, and the processing unit is disposed in the outer ring of the massage ring. The inner ring diameter of the massage ring 1 is 7 cm, which is derived from the average diameter of the patella in Chinese people, and the outer ring diameter is 9 cm.

[0025] Multiple pneumatic massage units periodically inflate and deflate, pushing the patella to move and slide it in various directions, preventing patellar adhesion. Figure 2 As shown, the pneumatic massage unit 11 includes a telescopic airbag 112, an inflation pump 113, a deflation pump 114, and an air chamber 115. A pressure sensor 111 is provided on the surface of the telescopic airbag 112. The surface of the telescopic airbag is made of silicone and has several elastic protrusions (not shown in the figure) to increase the skin-friendly texture and friction. The inflation pump and the deflation pump are located between the telescopic airbag and the air chamber to control the inflation and deflation of the telescopic airbag. During operation, each pneumatic massage unit is inflated. When the pressure sensor reading reaches the contact threshold, the inflation stops to ensure all units are in contact with the patella. Then, the currently operating pneumatic massage unit is selected and inflated, pushing the patella forward. During this movement, a monitoring pneumatic massage unit symmetrical to the currently operating unit is identified. The pressure sensor reading of this monitoring unit is used to determine if the patellar displacement meets the requirements. If it does, this is maintained for 5 seconds. Then, the currently operating pneumatic massage unit is slowly deflated until its pressure sensor reading reaches the contact threshold. The next pneumatic massage unit is selected clockwise as the operating unit, and this inflation and deflation process is repeated until all units have completed their movement.

[0026] Multiple infrared emitting units work together to heat and treat the patella, promoting blood circulation and acting as a warm-up before the procedure.

[0027] The processing unit controls the operating parameters of the massage ring. It includes a voice interaction module, which receives the patient's adjustment commands and selects suitable operating parameters. These parameters include infrared heating power, infrared heating duration, and patellar displacement.

[0028] The working process of the patellar repositioning assist device includes:

[0029] S1. The patient lies supine. Place the massage ring on the patella, with the patella in the center of the massage ring. Wrap the fixation strap around the knee joint and connect the two ends of the massage ring together by adhesive to achieve fixation.

[0030] S2. The patient activates the massage ring via voice interaction and sets appropriate working parameters. The massage ring starts working based on the selected working parameters. When the massage ring is working, it first activates the infrared emitting unit for heating therapy. After the heating therapy is completed, it activates the pneumatic massage unit to move the patella.

[0031] S3. After the massage ring is finished, it returns to its initial state, and the patient removes the massage ring.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] Patellar repositioning training is performed through the combined use of an infrared emitting unit and a pneumatic massage unit. This approach ensures training quality while improving comfort. Furthermore, the operation is conducted via voice interaction, making it simple, convenient, and easy for patients to use.

[0034] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. It should be noted that any equivalent variations made to the present invention by those skilled in the art without departing from its design structure and principles are considered within the scope of protection of the present invention.
