Auxiliary exercise device for preventing finger joint stiffness during arm fracture nursing

Abstract

The invention discloses an auxiliary exercise device for preventing finger joint stiffness during arm fracture nursing. The auxiliary exercise device comprises a palm placing plate and an electric push rod, wherein one end of the palm placing plate is connected with an arm supporting plate through an angle adjusting structure, and the other end of the palm placing plate is detachably provided witha four-finger exercise end. A rhombic opening rod is driven by an electric telescopic rod to move backwards, so that a rope fixing plate can also move backwards along with the rhombic opening rod, atthe moment, a lower knuckle fixing area, a middle knuckle connecting area and an upper knuckle fixing area can be driven to rotate downwards under the action of the rope fixing plate and a connectingrope, and as a result, fingers are driven to carry out holding exercise, when the electric telescopic rod drives the rhombic opening rod to move forwards, the lower knuckle fixing area, the middle knuckle connecting area and the upper knuckle fixing area are reset under the action of a first torsion spring, so that the four fingers are straightened along with the rhombic opening rod, and the fourfingers are subjected to bending and stretching exercise.

Description

technical field [0001] The invention relates to the technical field of auxiliary exercise devices, in particular to an auxiliary exercise device for preventing stiffness of finger joints used in arm fracture care. Background technique [0002] After people's arm fractures, the activities of the fingers will be very stable. Most patients will choose to let the fingers not only move. If things go on like this, it is easy to make the joints of the fingers stiff at the beginning, and many people have joints caused by various accidents. Defects in finger function. At the same time, as the aging speed accelerates, more and more people suffer from diseases such as stroke or paralysis. In order to help these finger dysfunctions to perform finger training, finger assisted exercise devices have become a research hotspot. There are many There are many finger exercise devices, but most of them can only guide the fingers to perform simple bending and straightening operations, and cannot...
