Description

An inflatable protective seat for stroke patients

technical field

The invention relates to the field of medical devices, in particular to an inflatable protective seat for stroke patients.

Background technique

Stroke is a common cerebrovascular disease with a high morbidity and disability rate. According to epidemiological surveys, the number of new strokes in China is about 1.5 million every year, and the number of survivors after the disease is as high as 5 million. 75% have lost the ability to work to varying degrees, and more than 40% are severely disabled.

The affected limbs of hemiplegic patients are inconvenient to move, and chairs have become a necessary tool for most hemiplegic patients. However, the chairs in the prior art have the following defects and deficiencies:

First, for obese stroke patients, due to sedentary reasons. The patient's body and the seat are in airtight contact, which often leads to problems such as bedsores and low back pain.

Secondly, when a hemiplegic patient sits on a seat in the prior art, the patient's lower limbs are usually placed in a fixed manner, and the lower limbs of the hemiplegic patient cannot receive rehabilitation training.

In addition, the lumbar back muscles of hemiplegic patients have no strength, and the hemiplegic patients cannot independently control their sitting posture.

Furthermore, for obese hemiplegic patients, when the patient sits and stands, the patient's sacrococcygeal and ischial tuberosities are particularly stressed, causing the patient to cause problems such as interfemoral dehiscence.
