Abstract

The utility model relates to a recovering body building wheelchair for brain paralysis patients. The lower part of a wheelchair frame is fixed with a motor and a speed reducer. The speed reducer drives a back axle to rotate and both ends of the back axle are respectively fixed with a tooth wheel with a flywheel structure. Wheel hubs of the back wheels are fixedly connected with transmitting wheels on middle parts of the tooth wheels. A front support bracket of the wheelchair frame is fixed with an axle, an axle handle, a tooth wheel plate and pedals. Tooth wheels of the back axle and the tooth wheel plate are connected by a chain. The axle handle on an outer side of the support bracket is fixed with one end of a connecting rod. The upper end of the connecting rod is fixed with a support board which is provided with a hand support. The utility model enables the patient's limb to move by the motor or by manually pushing the wheelchair in order to reduce the nursing labor intensity. The utility model with convenient use enables the patient to sit on the wheelchair to conduct indoor or outdoor limb exercise.

Description

Cerebral palsy recovery and healthy wheelchair

This utility model relates to wheelchair.

The cerebral palsy that causes owing to apoplexy, permanent disability and reason such as congenital causes the limbs can't active patient, make its limbs can be under the effect of external force as much as possible activity be that the patient gets well or alleviates the key of disease.Because the motion of limbs can stimulate the recovery of paralysis brain, promote the blood acceleration cycle, help the patient and absorb drug effect.At present, the external force of this patient's limb activity all is to provide by other people, because nursing amount and labor intensity are big, make the people be difficult to adhere to for a long time, thereby influences patient's treatment.

The purpose of this utility model is to provide a kind of cerebral palsy recovery and healthy wheelchair that can provide external force to make its limb activity to the cerebral palsy patient.

The purpose of this utility model realizes by technical scheme shown in the drawings, it comprises two trailing wheels, two universal little front-wheels, wheelchair frame, a bracing frame is fixed in the bottom of wheelchair frame of the present utility model, fix a motor 9 and decelerator 8 on the bracing frame, fix a gear wheel dish 10 on the rear axle 12, the gear wheel dish links to each other by the flywheel 13 on the output shaft of chain and decelerator, each fixes a gear wheel 11 two ends of rear axle, the embedded drive 15 in gear wheel middle part, unidirectional ratchet structure is arranged between drive and gear wheel, constitute flywheel, two trailing wheels are by the two ends of bearing fixing at rear axle, and the wheel hub 14 of trailing wheel is affixed with the drive at gear wheel middle part; Respectively there is a support both sides, the place ahead of wheelchair frame bottom, the support front end is fixed with the axle identical with the bicycle middle shaft structure, be fixed on footstalk 6 and gear wheel dish on the axle, be fixed on riding on the footstalk, gear wheel dish on the axis is connected by chain 7 with gear wheel on the rear axle, the foot-operated structure that can fold upward of making of support inboard, do not establish foot-operated on the footstalk in the support outside, on the footstalk in the outside, fix an end of a connecting rod 3, fix a bearing pin 5 at the middle part of wheelchair, there is through hole the termination of bearing pin, bearing pin can rotate around the axis of oneself, the middle part of connecting rod is inserted in the through hole of bearing pin, a supporting plate 1 is fixed in the upper end of connecting rod, and supporting plate is provided with hand rest 2, and the finger-stall of being made by elastomeric material is arranged on the hand rest, be fixed with a backguy 4 below each finger-stall, the termination after the backguy set is fixed on the wheelchair frame.

Patient is sitting on this wheelchair, the forearm of upper limb is placed on the supporting plate, finger inserts in the finger-stall, on foot was placed on and rides, work process of the present utility model was as follows, and the gear wheel that drives the rear axle two ends when motor rotates rotates, in the case, trailing wheel is motionless, and the transmission by chain is rotated the footstalk on the support, drives patient's leg exercise; Simultaneously, connecting rod drives supporting plate and moves up and down, and makes upper extremity exercise; Because the length of the backguy under the finger-stall changed with the rotation of the footstalk cycle of doing, finger-stall is also being done telescopic movable, makes finger obtain motion.When patient needed activity out of doors, without motor, the gear wheel on rear axle under the effect of ratchet structure was driven together by transmission and rotated, thereby realizes above-mentioned motion owing to the rotation of trailing wheel this moment.And motor and decelerator are because rotation together thereupon of the effect of its flywheel.

This utility model is simple and reasonable for structure, can make patient's limb activity by motor, also can promote wheelchair and make patient's limb activity, thereby alleviate the labor intensity of nursing by the people, heavy, vexatious nursing work is oversimplified, can be improved the rehabilitation of patients rate greatly.This utility model can make the patient be sitting on the wheelchair to carry out limb activity at indoor or outdoors, and is extremely easy to use.
