Description

A pressure-measurable inflatable non-invasive ventilator mask for preventing pressure sores

Technical Field

The utility model belongs to the technical field of medical equipment and particularly relates to a pressure-measurable inflatable pressure-ulcer-proof non-invasive ventilator mask.

Background Art

Non-invasive ventilation has good therapeutic effects on sleep apnea syndrome, acute and chronic respiratory failure, and invasive ventilation weaning treatment. When using a non-invasive ventilator clinically, the mask is usually placed on the patient's face and the mask is worn by adjusting the tightness of the headband. If the headband is adjusted too loosely, the mask is easy to move, and the air leakage is large, and the treatment effect cannot be achieved; if the headband is too tight and the mask is worn for too long, it is easy to cause facial pressure sores and reduce the patient's comfort. Once a pressure sore occurs, it will not only increase the patient's pain and treatment costs, but also seriously affect their continued cooperation with the use of ventilator treatment. Facial scars in the future will also greatly reduce the satisfaction of patients and their families.

At present, there are many kinds of non-invasive ventilator masks used in clinical practice, including nasal masks, nasal pillows, oronasal masks, full-face masks, etc. Among them, oronasal masks are widely used. Oronasal masks cover both the nose and mouth, from the lower lip to the bridge of the nose, forming an enclosed space for oral and nasal breathing. The shape of the oronasal mask is generally triangular, with the bridge of the nose as one of the fulcrums of the triangle, and the corners of the mouth on both sides as the other two fulcrums. The three fulcrums form a stable triangle, which is elastically adjusted by straps. The bridge of the nose is the hardest hit area for pressure sores caused by oronasal masks. In order to reduce the pressure on the bridge of the nose, a mask that disperses the pressure on the bridge of the nose was developed, that is, the triangle at the bridge of the nose is extended to form a bridge directly to the forehead, and part of the pressure is transferred to the forehead, which is helpful to reduce the pressure on the bridge of the nose. However, for patients with poor cooperation, restlessness, and too long or too short faces, the fixing strap on the forehead is difficult to be effectively fixed. In addition, although the current mask that is in direct contact with the patient is relatively soft silicone, it is still easy to form pressure sores if the face is compressed for a long time. In order to reduce the incidence of pressure sores, clinical nurses usually use some decompression materials to pad the patient's face, such as cotton pads, foam dressings, etc. However, both cotton pads and foam dressings require additional shape cutting, are difficult to fix, and are easy to shift. Nurses need to repeatedly fix them and they are easily contaminated. The inflatable non-invasive mask developed by Hu Xiaodi and others can also effectively prevent pressure sores on the patient's face, but the inflation pressure is difficult to measure. If the inflation is insufficient, the mask and the skin are not well fitted. If the inflation is excessive, the pressure is too high, and the patient's comfort level decreases. In view of the above-mentioned defects of the existing ventilator masks, it is urgent to develop a mask with a relatively objective and constant pressure to avoid patient discomfort caused by excessive or insufficient pressure, thereby increasing the patient's cooperation with ventilator treatment and accelerating patient recovery.
