Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a multifunctional corrector for hemiplegic upper limbs. Background Art

[0002] During the recovery process of hemiplegic limbs, stroke patients often experience increased muscle tone in the upper limbs. This increased muscle tone can lead to a variety of abnormal postures and pain, such as shoulder adduction, elbow flexion, forearm supination, and accompanying wrist and finger flexion deformities. These abnormal conditions exist for a long time, are difficult to correct, and the correction process is long, and are often accompanied by upper limb pain, edema on the back of the hand, etc.

[0003] In order to improve this situation, the medical community has been exploring effective rehabilitation equipment. Prior art such as CN216823917U discloses an upper limb good posture positioner for hemiplegic patients using wheelchairs. However, it has the following problems: 1. The device as a whole is relatively bulky and is not a wearable structure, so the patient cannot perform other activities during rehabilitation correction; 2. The function is single, and it can only place the patient's upper limbs to the corresponding position, but it cannot effectively correct multiple positions such as the palm, shoulder, and wrist. 3. It cannot relieve muscle tension, resulting in only being able to correct the patient's upper limb posture, but it cannot solve the problem of increased muscle tension. In addition, forced correction without relieving muscle tension will also increase the patient's pain.
