Rubber mat for reducing occurrence of pressure sores during use of non-invasive ventilator

Abstract

The invention belongs to the technical field of medical rubber mats, and particularly relates to a rubber mat for reducing occurrence of pressure sores during use of a non-invasive ventilator. The rubber mat includes a hydrogel layer, a penetration absorbent and buffer layer and a breathable and water barrier layer, one side of the penetration absorbent and buffer layer is closely attached to thehydrogel layer, the other side of the penetration absorbent and buffer layer is closely attached to the breathable and water barrier layer. According to the rubber mat, the rubber mat is prepared in ashape corresponding to a mask and placed in the mask, direct contact between the mask and skin is avoided, because the rubber mat is smooth, soft and good in breathability, pressure of the mask on the skin can be reduced, and free breathing of the skin can also be protected; in addition, the rubber mat can effectively absorb skin secretion, the skin PH value is maintained, the moderate temperature is maintained, and thus the occurrence of the pressure sores is prevented; and the comfort and compliance of patients receiving non-invasive ventilation treatment can be improved.

Description

technical field [0001] The invention relates to the technical field of medical rubber pads, in particular to a rubber pad used to reduce pressure sores during the use of a noninvasive ventilator. Background technique [0002] Pressure sores, also known as pressure ulcers or decubitus ulcers, are due to long-term pressure on local tissues, resulting in continuous ischemia, hypoxia, and malnutrition, resulting in tissue ulceration and necrosis. Skin pressure sores are a common problem in rehabilitation and nursing care. [0003] Non-invasive ventilator therapy is a mechanical ventilation method that uses a nasal mask to connect the ventilator circuit to the patient. It can effectively improve the patient's lung ventilation, relieve respiratory muscle fatigue, and correct respiratory failure. At the same time, it also avoids complications related to tracheal intubation or tracheotomy, preserves the defense function of the upper airway, preserves the patient's language and swal...

AI Technical Summary

Problems solved by technology

However, in the clinical use of patients, due to the long-term pressure of the mask on the facial skin, the local blood on the face is blocked, which in turn causes ischemia of the skin and subcutaneous tissue to form pressure sores, which seriously affects the comfort and compliance of patients using non-invasive ventilator treatment.

[0004] The inducing factors of pressure sores mainly come from the vertical pressure, frictional force and humidity inside the mask. The patient wears a breathing mask for a long time to compress the facial skin and subcutaneous tissue, while the bridge of the nose and the facial skin of the cheeks lack adipose tissue protection, and the muscle layer is thin, making the face The skin is under constant pressure; the mask rubs against the patient's face, bridge of the nose, and cheeks more frequently; in addition, the gas exhausted by the patient's breathing accumulates in the mask, and the humidity gradually rises, which can easily cause skin infection and ulcers, resulting in a higher risk of facial pressure sores Big

Conventional nursing countermeasures in the past, such as taking the mask to rest and cleaning the skin, can reduce the possibility of pressure sores to a certain extent, but cannot achieve the expected clinical effect
