Description

Inflatable pressure sore-preventing noninvasive respirator mask capable of measuring pressure

Technical Field

The utility model belongs to the technical field of medical equipment and equipment, and particularly relates to a pressure-measurable inflatable pressure sore-preventing noninvasive respirator mask.

Background

The noninvasive ventilation has good curative effects on sleep apnea syndrome, acute and chronic respiratory failure, off-line treatment for assisting invasive ventilation and the like. When a noninvasive ventilator is used clinically, a mask is usually covered on the face of a patient, and the mask is worn by adjusting the tightness of head wearing. When the head is excessively loose, the mask is easy to move, the air leakage is large, and the treatment effect cannot be achieved; the face pressure sore is easily caused by excessively tightening the head and excessively long wearing time of the mask, and the comfort level of the patient is reduced. In addition, once pressure sore occurs, the pain of a patient is increased, the treatment cost of the patient is increased, the patient is seriously influenced to continue to be matched with the treatment of the respirator, and the satisfaction degree of the patient and family members of the patient can be greatly reduced due to the fact that the face is left with scars in the future.

The noninvasive breathing machine mask used clinically at present is five-flower eight-door and comprises a nose mask, a nose pillow, an oral-nasal mask, a full face mask and the like. The nose and mouth mask is widely applied, namely, the nose and mouth mask is covered by the nose and the mouth, and a closed space for breathing from the lower lip to the nose bridge is formed. The shape of the nose-mouth cover is generally triangular, the nose bridge is used as one supporting point of the triangle, the mouth corners on two sides are the other two supporting points, the three supporting points form a stable triangle, and the nose-mouth cover is elastically adjusted through the binding belt. The nose bridge is the disaster area where pressure sore caused by the nose and mouth mask occurs. In order to relieve the pressure at the nose bridge, a mask for dispersing the pressure of the nose bridge is developed, namely, the triangle at the nose bridge is prolonged, so that a bridge is formed to reach the forehead, partial pressure is transferred to the forehead, and the mask has a certain help for relieving the pressure of the nose bridge. However, for patients with poor fitting degree, agitation, too long or too short facial form, the fixing strap at the forehead is difficult to effectively fix. In addition, although the direct contact part of the mask and the patient is made of soft silica gel, pressure sores are still easy to form when the face is pressed for a long time, and clinical nurses often use a plurality of pressure reducing materials to cushion the face of the patient, such as cotton pads, foam dressings and the like, in order to reduce the occurrence rate of the pressure sores. However, the cotton pad and the foam dressing are required to be additionally cut in shape, are difficult to fix and easy to shift, require a nurse to repeatedly fix again and are easy to pollute. Hu Xiaodi et al, can also effectively prevent that patient's face from producing pressure sore, but inflated pressure is difficult to measure, and the inflation is not enough, and face guard and skin laminating degree are not good enough, and the air inflation is too high, and the pressure is too high, and patient's comfort level descends. In view of the above-mentioned drawbacks of the existing respiratory mask, it is highly desirable to develop a mask with relatively objective and constant pressure, which avoids discomfort of the patient caused by too high or too low pressure, thereby increasing the degree of coordination of the patient to the respiratory therapy and accelerating the recovery of the patient.
