Description

A device for preventing pressure sores for palliative care

Technical Field

The utility model relates to the technical field of medical assistance, in particular to a device for preventing pressure sores for palliative care.

Background Art

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. Skin pressure sores are a common problem in rehabilitation treatment and nursing, and anti-pressure sore devices are needed to prevent them.

For example, the authorization announcement number "CN215021019U" is named as an anti-pressure sore device for palliative care. Although, when pressure is applied to the buttocks, the middle part of the buffer bracket is in a hollow state, and the compressed air can flow through the honeycomb holes and the vents, so that the anti-pressure sore pad body can achieve a ventilation effect and facilitate air circulation, but the existing anti-pressure sore device still has the problem of being placed on the two upper grooves on both sides of the buttocks during use, and the front groove in the middle is not in contact with the buttocks, and a plurality of vents are provided at the upper end of the anti-pressure sore pad body. When the buttocks move, pressure is applied to the buttocks, and the middle part of the buffer bracket is in a hollow state, and the compressed air can flow through the honeycomb holes and the vents, so that the anti-pressure sore pad body can achieve a ventilation effect, facilitate air circulation, and be beneficial to ventilation under the buttocks, which can avoid the formation of pressure sores.
