Description

Technical Field

[0001] The invention relates to the technical field of nursing, and in particular to a medical nursing mattress. Background Art

[0002] Pressure sores, also known as pressure ulcers and bedsores, are caused by long-term pressure on local tissues, resulting in continuous ischemia, hypoxia, and malnutrition, leading to tissue ulceration and necrosis. Pressure sores are more common in patients who are bedridden for a long time and cannot adjust their body position independently.

[0003] For patients who are bedridden for a long time, the measure to prevent pressure sores is mainly for medical staff to change the patient's position regularly to relieve the long-term pressure on the patient's local tissue. However, frequent turning over can easily cause local wear and tear on the patient's skin and cause unnecessary pressure sores. In addition, the mattresses currently used in hospitals cannot adjust the pressure on the patient's skin, which is not conducive to the prevention of pressure sores for patients who are bedridden for a long time.
