Face dressing for preventing air leakage of breathing mask

Abstract

The invention discloses a face dressing for preventing air leakage of a breathing mask.The face dressing comprises a dressing body, a face adhesive patch and a mask adhesive patch.The two faces of the dressing body are coated with an adhesive to form adhesive layers.The two faces of the dressing body are connected with the face adhesive patch and the mask adhesive patch respectively through the adhesive layers.The gap between the mask and the face is filled with the dressing body, the stability of the fixed position of the mask can be guaranteed, and meanwhile air leakage caused by face muscle movement in the use process of the mask is reduced.By means of the face dressing, the effectiveness of face ventilation is improved, stability of treatment pressure of a breathing machine is guaranteed, and therefore the use comfort degree and compliance of a patient are improved.

Description

technical field [0001] The invention relates to the medical field, in particular to a face dressing for preventing air leakage of a breathing mask. Background technique [0002] Non-invasive ventilation: It was mainly used for sleep-respiratory syndrome in the early stage. In the past 10 years, this technology has been widely used in the treatment of various acute and chronic respiratory failures. During non-invasive ventilation, the ventilator is connected to the patient through an oral or nasal mask for positive pressure ventilation, without the need to establish an invasive artificial airway. When the patient has obvious problems such as abnormal respiratory mechanics and respiratory muscle fatigue, but the problem of sputum drainage is relatively minor, it is the best time to apply non-invasive ventilation. [0003] In non-invasive ventilation therapy, the tightness, comfort and tolerance of the contact surface between the person and the mask are the key factors affecti...

AI Technical Summary

Problems solved by technology

[0003] In non-invasive ventilation therapy, the tightness, comfort and tolerance of the contact surface between the person and the mask are the key factors affecting the success of the ventilation therapy. The contact surface between the existing breathing mask and the user is mostly composed of synthetic gel or silicone material, not only It is easy to cause air leakage, which directly affects the effectiveness of ventilation therapy, and the air leakage compensation mechanism of the ventilator may also easily cause discomfort to patients and indirectly affect compliance with use; in addition, there are also many reports of users who are allergic to gel or silica gel
