Wrist turnover function rehabilitation training device

Abstract

The invention relates to a wrist turnover function rehabilitation training device which comprises a supporting body, a turnover mechanism and a driving mechanism, wherein the supporting body comprisesa base and a supporting frame; the turnover mechanism comprises a turnover plate, a turnover shaft, a rotating block and a gear; the turnover plate and the gear are fixed to two ends of the turnovershaft respectively; the turnover shaft swings on the supporting frame and enables the turnover plate to keep the trend of downward swinging all the time through a torsional spring, a pressing head isfurther arranged on the outer side of the gear; the driving mechanism comprises a motor, a main shaft, an upper rotary disc and a lower rotary disc; the motor drives the upper rotary disc and the lower rotary disc which are coaxially fixed to the main shaft and provided with a protruding edge and a rack correspondingly. When the device is in use, a palm of a patient is fixed on the turnover plate,the motor drives the upper rotary disc and the lower rotary disc to rotate, the protruding edge gradually makes contact with the pressing head along with rotation of the upper rotary disc and pressesthe pressing head downwards to enable the turnover plate to swing upwards, and meanwhile the gear swings downwards to be meshed with the rack so as to drive the turnover plate to rotate by 180 degrees to achieve turnover of the hand; and the turnover plate swings downwards reversely under the action of the torsional spring, and wrist pressing is achieved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation equipment, in particular to a rehabilitation training device for wrist turning function. Background technique [0002] The rehabilitation of patients with hemiplegia, stroke or cerebral palsy, and patients with central nervous movement disorders caused by some burn patients has become a major social problem. According to the development characteristics of the human body, the recovery of the nerves and muscles at the end of the limbs is the slowest. Therefore, the rehabilitation process Among them, the rehabilitation treatment of the extremity joints such as the wrist joint is the most critical. In addition, in the clinical treatment process, the movement of the terminal joints is often affected by the muscles at the proximal end of the body, and the movement of the limbs also mainly depends on the contraction of the muscles at the proximal end of the body. , so that the muscles that control...

[0002] The rehabilitation of patients with hemiplegia, stroke or cerebral palsy, and patients with central nervous movement disorders caused by some burn patients has become a major social problem. According to the development characteristics of the human body, the recovery of the nerves and muscles at the end of the limbs is the slowest. Therefore, the rehabilitation process Among them, the rehabilitation treatment of the extremity joints such as the wrist joint is the most critical. In addition, in the clinical treatment process, the movement of the terminal joints is often affected by the muscles at the proximal end of the body, and the movement of the limbs also mainly depends on the contraction of the muscles at the proximal end of the body. , so that the muscles that control the terminal joints cannot be trained. The traditional rehabilitation treatment methods are mainly one-on-one manual treatment by the therapist, and simple rehabilitation equipment is attached. The existing wrist joint rehabilitation equipment has a single training action And the types are limited, and only simple swinging activities can be performed on the wrist. Originally, the movement form of the wrist joint is relatively complicated. These simple rehabilitation equipment have great limitations on the rehabilitation of the wrist joint. With the increasing number of such patients, relying on simple Traditional manual treatment or simple rehabilitation equipment are difficult to meet the rehabilitation needs of patients. Therefore, there is an urgent need for a rehabilitation training device for the wrist joints of patients with central nervous movement disorders.
