Non-invasive ventilation indwelling gastric tube mask

Abstract

The invention relates to a non-invasive ventilation indwelling gastric tube mask. The mask comprises a mask body. The mask body is provided with a connector used for being connected to an air tube. The mask is characterized in that a stomach tube leading-out hole is formed in the mask body. A connecting cylinder corresponding to the stomach tube leading-out hole is arranged on the outer surface of the mask body. A stomach tube restraining sleeve suitable for fixing stomach tubes of various specifications is installed in the connecting cylinder and made of a soft elastic material. A limiting table is arranged at the end, close to the stomach tube leading-out hole, of the inner surface of the connecting cylinder. The inner end of the stomach tube restraining sleeve abuts against the limiting table. The outer end of the connecting cylinder is provided with a jacking cover for pressing against the stomach tube restraining sleeve. The center of the jacking cover is provided with a hole and is provided with a sealing cover. A supplementary cushion layer used for reducing air leakage is arranged on the inner side face of the edge of the mask body. The mask is ingenious in structure, reasonable in design, convenient to use and very good in air leakage prevention effect, and the problem of man-machine discordance caused by air leakage can be effectively solved.

Description

technical field [0001] The invention relates to a ventilating mask, in particular to a non-invasive ventilating indwelling gastric tube mask, which belongs to the technical field of medical appliances. Background technique [0002] Non-invasive positive pressure ventilation (NPPV) refers to ventilation without artificial airway (tracheal intubation or tracheotomy). The machine provides positive pressure support and completes the artificial ventilation mode of ventilation assistance. In recent years, non-invasive positive pressure ventilation has made significant progress in clinical research and has become a routine respiratory support method for respiratory failure caused by various diseases. However, the successful application of non-invasive positive pressure ventilation largely depends on the tolerance of patients to non-invasive positive pressure ventilation. Non-invasive positive pressure ventilation intolerance refers to that the patient feels discomfort and irritab...

AI Technical Summary

Problems solved by technology

[0003] In the clinical nursing work of non-invasive positive pressure ventilation, many elderly patients have indwelling gastric tubes. When using the ventilator mask, the indwelling gastric tube faces the problem of being pressed under the mask, which will cause the mask to leak, and the face is also prone to pressure injury

In addition, some patients with thin faces or missing teeth also have the problem of loose faces when using ventilator masks, and the masks are prone to air leakage during use

Air leakage is one of the main reasons for man-machine incoordination. If the air leakage exceeds a certain range, it will easily cause man-machine out of sync and cause patients intolerance.
