Description

An adjustable pressure relief pad suitable for non-invasive ventilation

Technical Field

The utility model relates to an adjustable pressure-reducing pad suitable for non-invasive ventilation, and relates to the technical field of medical devices.

Background technique

Non-invasive ventilator support ventilation is also called non-invasive positive pressure ventilation. It is widely used in the daily treatment of patients with chronic hypoxia such as chronic obstructive pulmonary disease and sleep apnea syndrome. It is also used in the rescue treatment of acute respiratory failure and acute heart failure. Patients can reduce the chance of endotracheal intubation by using non-invasive ventilators. However, the current non-invasive ventilator masks are easy to cause pressure marks on the face when worn for a long time, and there is a certain probability of pressure sores, which reduces the comfort and compliance of patients.

At present, the new protective dressings (hydrocolloid dressings, foam dressings, liquid dressings, film dressings, gel dressings, etc.) are cut into shapes that match the masks and then placed between the ventilator masks and the face to avoid pressure sores. However, the dressings are inconvenient to cut during use, and medical staff need to cut them according to different patients and mask sizes. There is no fixed structure, and the gaskets placed between the face and the mask are prone to misalignment. Some dressings are prone to decreased adsorption, deformation and hardening after contact with a heated and humidified environment, which reduces the airtightness of the ventilator mask and affects the effect of wearing the machine. In addition, when using hydrocolloid dressings, the hydrocolloid dressings need to be replaced every 1-3 days to avoid the phenomenon of the hydrocolloid dressings turning white and deteriorating, which reduces the effect of wearing the non-invasive ventilator.
