Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation nursing equipment, in particular to a wheelchair that is convenient for sitting and standing recovery training. Background Art

[0002] Neurosurgery is a department that mainly treats brain diseases. For partial brain tissue damage caused by trauma or tumors, since brain tissue is a non-regenerative cell, it is generally difficult to regenerate once it dies. Because brain tissue corresponds to various parts of the human body, patients with cranial nerve necrosis will have certain functional disorders. The main training method is physical exercise to enhance muscle coordination.

[0003] Some neurosurgery patients can only sit in a chair all year round and lack proper rehabilitation training, which can easily lead to physical discomfort and weakened lower limb motor function. The traditional way of rehabilitation training is mainly for the patient to lie in bed and the patient's family members to pull the patient's legs to achieve the training effect, which makes the rehabilitation training more cumbersome. For this reason, we propose a wheelchair that is convenient for sit-stand recovery training. Summary of the invention

[0004] The purpose of the utility model is to provide a wheelchair that is convenient for sit-to-stand recovery training, so as to solve the problem that the traditional rehabilitation training proposed in the above background technology is that the patient's family pulls the patient's legs, making the rehabilitation training more cumbersome.
