Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation machinery, in particular to a finger flexion and extension assistor. Background Technique

[0002] Diseases such as stroke, traumatic brain injury, and hand trauma are important reasons for the loss of finger function in patients. In addition to relying on drug treatment, if finger rehabilitation training is carried out, the treatment effect can be greatly improved and the treatment time can be shortened. However, due to the boring nature of finger rehabilitation training movements, it is difficult for doctors or patients themselves to ensure the cycle and intensity of rehabilitation training, and patients often cannot persist for a long time. Therefore, some people have designed finger rehabilitation devices that use mechanical energy to drive the patient's fingers to bend and stretch reciprocally to achieve the training purpose.

[0003] The existing patent (publication number: CN219332393U) proposes a desktop finger flexion and extension rehabilitation assistor, which includes a chassis, a motor, and a controller. The upper opening of the chassis is equipped with an upper cover through a hinge. An armrest is fixedly installed on the upper cover, and a magic tape is installed on the armrest. A controller, a battery, a motor, and a driving device are installed in the chassis. The motor shaft of the motor is connected to a push plate located outside one side of the chassis through the driving device to form a structure in which the push plate reciprocates horizontally. The push plate is connected to the front end of the glove; a switch button, a display screen connected to the controller, a speed regulator, and a timer are installed outside the chassis. The speed regulator is connected to the motor. The switch button, the motor, and the controller are connected to the battery to form a control structure.

[0004] The above device realizes active and passive finger flexion and extension, reduces the abnormal muscle tension of patients, and promotes blood circulation in the hand. However, it cannot adjust the fingers of patients. The fingers of different patients are of different thicknesses, which will cause the fingers of patients to be squeezed. Therefore, we propose a finger flexion and extension assistor. Content of the Utility Model
