Description

Technical Field

[0001] The utility model relates to the technical field of medical care instruments, in particular to a grasping training device for stroke patients. Background Technique

[0002] Stroke, also known as "apoplexy", is an acute cerebrovascular disease. It is a group of diseases caused by sudden rupture of blood vessels in the brain or inability of blood to flow into the brain due to blood vessel blockage, including ischemic and hemorrhagic strokes. Stroke patients will have insufficient grasping strength in the hand, so a grasping rehabilitation training device is needed to rehabilitate the patient's hand.

[0003] In the existing grasping training device for stroke patients, during use, the patient's fingers are passed through the finger rings and an external force is applied to the elastic bands on the finger rings, and the grasping training of the patient's fingers is achieved by overcoming the resistance of the elastic bands. In the above method, during the training process, since the elastic bands are always exposed and have a certain specification, it is impossible to adjust the resistance force for overcoming the elastic bands according to the rehabilitation degree, which affects the training effect of the device. Therefore, there is an urgent need for a grasping training device for stroke patients to solve the above problems. Summary of the Utility Model
