Description

A mattress with dynamically adjustable support position

Technical field

The utility model belongs to the technical field of mattresses, and specifically relates to a mattress with dynamically adjustable support positions.

Background technique

The mattress is an important part of a person's sleeping environment. Especially for patients who are bedridden for a long time or have a weak constitution, a comfortable mattress can not only promote their sleep but also prevent the occurrence of pressure injuries. Existing mattresses generally have relatively simple functions. Most of them are in one piece and have a large thickness. Therefore, the deformation range is limited, and it is difficult to achieve functions such as assisting bedridden patients to turn over.

For bedridden patients with limited mobility or weak constitution, due to long-term maintenance of the same bed posture, the continuous pressure and the inability to perform independent and effective local decompression will lead to long-term compression of local tissues, obstructed blood circulation, and continuous ischemia, hypoxia, and nutritional deficiencies. Bad results in tissue ulceration and necrosis. Therefore, people who are bedridden for a long time need caregivers to help them turn over regularly. Some studies have pointed out that intermittent pressure can maintain blood perfusion of human tissues and reduce tissue damage. By regularly changing the amount of pressure on body parts, the probability of pressure injuries can be reduced.
