Description

simple bed seat

technical field

The utility model relates to the technical field of seats, in particular to a simple bed seat.

Background technique

After suffering from cerebrovascular disease, many elderly people have to stay in bed because they have lost the ability to shift their body positions autonomously. Long-term bed rest is a major factor that induces various complications, such as muscle atrophy, bone loss, and hypostatic pneumonia. There is also a negative impact on the patient's psychology. In the hospital, the training of the patient's position is often realized by lifting the bed and standing up the bed. However, patients at home do not necessarily have the conditions to install a lift bed at home. When nursing patients, they usually move the patient to sit up and place cushions, pillows, etc. behind him to maintain the patient's position. It is impossible to achieve a good posture, and often even half-sitting bit. This position will aggravate the limb spasms of hemiplegic patients, generate shear force at the skin interface and increase the risk of pressure sores, so it is required to avoid it when placing the position. In addition, if the patient's trunk control ability is poor, he will easily fall over, which will cause certain harm to the patient and his family. troubled. Existing bed seats are often used for leisure and frail elderly people, which cannot meet the post-stroke hemiplegia patient's posture requirements, and cannot be completely upright. The patient tends to slide down, which increases the risk of pressure sores.
