Description

Technical Field

[0001] The utility model relates to the field of rehabilitation training devices, in particular to a medical wrist joint rehabilitation training device. Background Art

[0002] With the rapid development of modern society, the number of patients suffering from wrist fractures caused by car accidents, falls from heights, mechanical injuries, sports injuries, and some accidental injuries has gradually increased. After the postoperative plaster fixation period, there will be certain symptoms such as limited wrist joint mobility (flexion and extension), soft tissue contracture, and joint stiffness. These symptoms seriously affect the patient's quality of life, such as work, eating, dressing, combing hair, etc., and there is an urgent need for a product to improve them.

[0003] Existing medical wrist joint rehabilitation trainers are bulky, have single functions, are cumbersome to adjust, and are troublesome to wear. They squeeze muscles during training, affecting blood circulation. The trainer has single functions and cannot stretch the joint capsule of the wrist joint, affecting the training effect. During training, the forearm cannot slide and displace with the changes in the flexion and extension angles of the wrist joint, which can easily cause muscle squeezing and affect blood circulation. Therefore, those skilled in the art provide a medical wrist joint rehabilitation trainer to solve the problems raised in the above background technology. Utility Model Content

The speed and rotation angle of the rotary machine can be adjusted according to the patient's rehabilitation needs to meet the training requirements of different patients in different rehabilitation stages, thereby improving the flexibility and pertinence of the training. Through the cooperation of the knob, screw rod, slider, slideway and spring pin, stretching training of the wrist joint capsule can be achieved. The operation is simple and convenient, and both patients and medical staff can operate it easily. At the same time, the hand support plate is made of stainless steel, which is sturdy and durable, easy to clean and disinfect, and stable. The outer shell and forearm support plate are made of plastic, which is light, low-cost and has good insulation. The patient's hand can be fully fixed through the hand strength cotton pad, five finger straps and two palm straps. The tightness of the straps can be adjusted according to the size and shape of the patient's hand to adapt to the needs of different patients, ensure that the palm remains stable during training, and prevent the fingers from moving at will.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a medical wrist joint rehabilitation trainer, comprising a base, a shell provided at the center of the upper end surface of the base, a rotating structure provided at the center of the rear end surface of the shell, a movable adjustment structure provided at the center of the lower inner wall of the base, a forearm support plate provided at the center of the upper end surface of the movable adjustment structure, a hand support plate provided at the center of the inner portion of the rotating structure, a stabilizing structure provided at the center of the upper end surface of the hand support plate, and a forearm structure provided at the center of the inner side wall of the forearm support plate;
