Hand function training device

Abstract

The invention discloses a hand function training device, comprising: an ellipsoidal inflatable airbag, five finger rings arranged on the surface of the ellipsoidal inflatable airbag according to a finger contraction direction, an inflating device connected with the ellipsoidal inflatable airbag through an inflating pipe and used for intermittently inflating the ellipsoidal inflatable airbag, an air discharge device connected with the ellipsoidal inflatable airbag and used for discharging air of the ellipsoidal inflatable airbag after the ellipsoidal inflatable airbag is inflated with air, anda control circuit connected with the inflating device and the air discharge device and used for controlling the inflating device and the air discharge device to alternatingly inflate and discharge airaccording to the set time. The device can train extensor muscles of hands by replacing a rehabilitation therapist who trains hand functions. The device can help a patient maintain a hand function position in order to reduce sequelae of hands. The device is convenient to carry and easy to operate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hand function trainer. Background technique [0002] In patients with cerebrovascular disease, due to infarction, the strength of the hand extensor muscle group is reduced and the flexor muscle group is hyperactive, resulting in a "chicken claw"-like change in the hand, loss of hand function, and long-term hand contractures that cause skin ulceration at the folds . [0003] At present, the limb rehabilitation training of patients with clinical cerebrovascular diseases is generally carried out by professional medical staff, but due to the limitation of medical human resources, it cannot meet the needs of each patient for full-time functional recovery training. And the hand function trainer that uses on the market at present is only applicable to the normal crowd that hand function exists to carry out hand function strengthening exercise, can't carry out hand flexion and...

Problems solved by technology

[0003] At present, the physical rehabilitation training of patients with clinical cerebrovascular diseases is generally carried out by professional medical staff, but due to the limitation of medical human resources, it cannot meet the needs of each patient for full-time functional recovery training.

However, the hand function training devices currently on the market are only suitable for normal people with hand functions to carry out hand function strengthening exercises, and cannot perform hand flexion and extension training for patients with reduced strength of hand extensor muscles
