Description

Liftable wheelchair

Technical Field

The invention relates to the technical field of medical instruments, in particular to a liftable wheelchair.

Background

A plurality of factors such as social aging, cardiovascular and cerebrovascular diseases, trauma and the like can cause a large number of patients with dyskinesia, namely hemiplegia, which is the dyskinesia of the upper and lower limbs, facial muscles and the lower part of the tongue muscle on the same side and is a common symptom of acute cerebrovascular disease. Although the mild hemiplegia patients can move, walking up and walking usually causes the upper limbs to bend and the lower limbs to straighten, and the paralyzed lower limbs draw half a circle by one step, which is called the hemiplegic gait. Serious patients are bedridden and lose the living ability, and need to be assisted by a wheelchair.

In daily life and in hospitals wheelchairs are the main means of transportation for critically ill or dyskinetic or hemiplegic patients. When the patient is examined in a hospital, the patient needs to be frequently transferred between the wheelchair and various examination beds for many times, the height of the existing wheelchair cannot be lifted, and the hemiplegic patient is difficult to transfer onto the bed surface from the wheelchair due to a certain height difference between the bed surface and the wheelchair cushion, so that an attendant is needed to assist the patient to transfer between the bed and the wheelchair. This requires not only a certain skill of the attendant but also considerable effort. Especially, a patient with a large weight often needs to be completed by cooperation of a plurality of persons, and great falling injury and gouge risks exist in the transferring process, so that great inconvenience is brought to the patient and accompanying personnel.
