The utility model provides a wheelchair for hemiplegic patients, which can solve the problem that the lateral limbs of the hemiplegic patients are not supported and the affected shoulder joint is in subluxation.
In order to solve the above problem, the utility model discloses the technical scheme who adopts is: the wheelchair for hemiplegic patients comprises a chair back, a chair seat and armrests, wherein mounting plates are respectively fixed at two ends of the inner sides of the armrests, turnover plates are hinged to the mounting plates, and telescopic rods extending towards the turnover plates and supported below the turnover plates when the turnover plates are opened are fixed on the mounting plates; and one end of the turnover plate, which is close to the chair back, is provided with a rotary handrail through a rotary positioning piece.
In the above technical solution, a more specific technical solution may also be: the rotary positioning piece comprises a rotary limiting block and a limiting block seat plate, the bottom surface of the rotary limiting block is abutted against the top surface of the limiting block seat plate, and the upper part and the lower part of the outer wall of the rotary limiting block are respectively provided with a limiting toothed ring; the rotary armrest is provided with an installation through hole for accommodating the rotary limiting block, the turnover plate is provided with a cavity for accommodating the lower part of the rotary limiting block and the limiting block seat plate, the opening end of the cavity is communicated with the installation through hole, the wall of the installation through hole is provided with a first toothed ring, and teeth of the first toothed ring are meshed with teeth of a limiting toothed ring at the upper part of the rotary limiting block; a second toothed ring is arranged on the cavity wall of the concave cavity; the teeth of the second toothed ring are meshed with the teeth of the limiting toothed ring at the lower part of the rotation limiting block; a telescopic guide pillar is arranged between the bottom surface of the cavity and the bottom surface of the limiting block seat plate, and a spring is sleeved on the telescopic guide pillar. Further: the rotating handrail is provided with a soft cushion layer.
Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has:
1. because the rotary armrest is arranged through the mounting plate and the turnover plate, the rotary armrest can be adjusted freely according to the position required to be supported by the upper limbs of a patient, not only can the affected side limbs of the hemiplegic patient be supported well, the hemiluxation of the shoulder joints of the hemiplegic patient be avoided, the rehabilitation is facilitated, the use is convenient, the transfer of the hemiplegic patient is not influenced, but also the rotary armrest can be folded below the original armrest when not used, the inner side of the original armrest is opened when used, the structure of the original wheelchair is not damaged, the use of other patients is not influenced, and the use function of the wheelchair is expanded.
2. Due to the structure of the rotary positioning piece, when the hemiplegic patient uses, the position of the rotary armrest can be adjusted by only pressing the rotary positioning piece, and the use is convenient and reliable.
