Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an auxiliary rehabilitation device for treating myasthenia gravis. Background Art

[0002] Myasthenia gravis is an autoimmune disease caused by dysfunction of neuromuscular transmission. Clinically, it manifests as partial or generalized skeletal muscle weakness and fatigue, which worsens with activity and improves with rest. In the early stages of myasthenia gravis, patients often experience soreness or discomfort in the eyes or limbs, blurred vision, and fatigue. As the disease progresses, skeletal muscle fatigue and weakness become apparent, with a notable increase in weakness in the afternoon or evening after fatigue and improvement in the morning or after rest.

[0003] Currently, myasthenia gravis is mainly treated with medication, supplemented by self-exercise recovery treatment by caregivers or patients. This not only increases the workload of caregivers, but also fails to achieve the training effect.

At the same time, in the process of the movable slider moving outward, it also drives the horizontal movable rod to move outward. When the horizontal movable rod moves, the vertical movable rod is pulled downward by atmospheric pressure. In the process of the vertical movable rod moving downward, the atmospheric pressure inside the cushion is reduced. When the arm is placed on the cushion, the cushion will sink downward under pressure, and the bottom of the folding block on the side will be compressed, causing the side to move toward the center, which can fit the arm during use and has a certain elasticity, thereby improving the comfort of the arm and being more conducive to rehabilitation training.

Massage block No. 2 and massage block No. 1 massage the front and back of the legs, thereby improving the exercise effect of rehabilitation training by massaging the leg muscles.

[0016] Beneficial effects:

[0017] 1. The auxiliary rehabilitation device for treating myasthenia gravis has the following advantages: after the arm is placed on the cushion, the weight of the arm presses the support plate and the support plate downward, and the support plate drives the connecting device to move downward. The connecting rod connected by the rotation at the bottom of the connecting device drives the movable slider to slide outward, and the movable slider transmits the pressure to the spring damper arranged on the side and converts the pressure into elastic potential energy through the spring damper and stores it. At the same time, in the process of the movable slider moving outward, it drives the horizontal movable rod to pull the vertical movable rod downward, and in the process of the vertical movable rod moving downward, the atmospheric pressure inside the cushion is reduced. When the arm is placed on the cushion, the cushion will be concave downward under pressure, and the bottom of the folding block on the side will be compressed to make the side move toward the center, so that it can fit the arm during use and has a certain elasticity, thereby improving the comfort of the arm and being more conducive to the progress of rehabilitation training.
