Description

Prevent pressing sore to use sick bed

Technical Field

The invention relates to the technical field of medical instruments, in particular to a hospital bed for preventing pressure sores.

Background

Pressure sores, also known as pressure ulcers and bedsores, are caused by tissue ulceration and necrosis due to persistent ischemia, hypoxia and malnutrition caused by long-term local tissue compression. Skin pressure sores are a common problem in rehabilitation and care. According to the literature, about 6 million people die from pressure sore union symptom every year.

Vertical pressure causes pressure sores primarily due to the localized tissue being subjected to constant vertical pressure, particularly in the bony tuberosity prominences of the body. Pressure sores can be caused if the patient lies in bed or sits on a wheelchair for a long time, the lining of the splint is improperly placed, the plaster is not flat or has dregs, and the part of the patient is pressed by more than normal capillary vessels for a long time (generally, the pressure which can be borne by blood vessels under the skin layer is about 32mmHg, and if the pressure exceeds the pressure, the local blood vessels can be twisted and deformed to influence the passing of blood flow, so that the phenomenon of ischemia exists).

The sickbed in the prior art cannot change the supporting force of the patient body in real time, is difficult to prevent the body of the patient from being pressed and sore, is difficult to realize the function of massage and promote the blood circulation of the patient, and in addition, the sickbed in the prior art does not have the function of heating, and particularly has poor comfort for the patient in winter.

Therefore, a hospital bed for preventing pressure sores is provided.
