Abstract

The utility model relates to a medical appliance, namely a noninvasive positive pressure ventilation mask of a breathing machine. The novel face mask comprises a face mask body, wherein four-point fixed rope belt fixing belts are arranged on the edges of two sides of the face mask body, and a stomach tube inserting hole which penetrates through the lower side of the face mask body is formed. The wall of the stomach tube insertion hole is lined with an annular inflatable air bag with a stomach tube through hole in the middle. The annular inflatable air bag is added at the insertion hole of the stomach tube, the air bag fills the gap around the stomach tube after being inflated, the air leakage of the gastrointestinal decompression or nasal feeding patients facing the noninvasive ventilation face is reduced, and the use requirement is ensured. The five-point middle rope belt fixing belt is added, the fixation is uniform, and the facial pressure injury caused by long-term use is reduced. Reasonable structure and convenient use.

Description

Noninvasive positive pressure ventilation mask of respirator

Technical Field

The utility model relates to a medical appliance, namely a noninvasive positive pressure ventilation mask of a breathing machine.

Background

In the prior art, the noninvasive positive airway pressure mask of the respirator comprises a mask body, wherein a silica gel layer is arranged at the buckling surface part on the periphery of the mask body, four-point fixed rope belt fixing belts and upper rope belt fixing belts are arranged at the edges of two sides of the mask body, and a stomach tube inserting hole and an oxygen hole which are penetrated through are arranged on two sides of the lower side beside the mask body. When gastrointestinal decompression or nasal feeding patients do noninvasive positive pressure ventilation, the stomach tube often extends from the silica gel part of the face mask to the outside of the face mask for fixation, so that a gap is generated between the face mask and the face mask part, the air leakage of the face mask is greatly increased, and the use and treatment are influenced. The two sides of the mask body are provided with the ropes to fix the mask, and the mask is fixed only by four points on the two sides, so that the mask is often tied tightly to prevent the mask from causing pressure injury to the face when air leakage is caused by gliding or nasal feeding and gastrointestinal decompression.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above insufficiency and provide a rational in infrastructure, wear comfortable, the good noninvasive positive pressure ventilation face guard of breathing machine of treatment.

The technical solution of the utility model is that: a noninvasive positive airway pressure mask of a respirator comprises a mask body, two side edges of the mask body are provided with four-point fixed rope belt fixing belts, two sides of the lower side of the mask body are provided with gastric tube inserting holes which run through, and the noninvasive positive airway pressure mask is characterized in that the wall of the gastric tube inserting hole is lined with an annular inflatable air bag with a gastric tube through hole in the middle.

In the above-mentioned scheme, the first step of the method,

the inside and outside sides of the stomach tube inserting hole are provided with a convex tube mouth.

The upper side of the mask body is provided with a middle rope belt fixing belt for forming five-point fixation.

The utility model has the advantages that: 1. The annular inflatable air bag is added at the insertion hole of the stomach tube, the air bag fills the gap around the stomach tube after being inflated, the air leakage of the gastrointestinal decompression or nasal feeding patients facing the noninvasive ventilation face is reduced, and the use and treatment requirements are ensured. 2. The fixing band on the rope belt of "five points" has been increased, adopts five points to fix, and is fixed even, can alleviate facial tissue's pressure, reduces the damage, improves patient's comfort level. 3. Rational in infrastructure, wear comfortable, convenient to use, treatment is good, has improved the tolerance and the compliance that noninvasive positive pressure ventilation treatment patient used noninvasive ventilator greatly.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic view of the structure of the present invention.

FIG. 2 is an enlarged schematic view of the annular inflatable bladder arrangement.

Detailed Description

Referring to fig. 1 and 2, the names of the components are as follows: the mask comprises a mask body 1, a rope belt fixing band 2, a stomach tube inserting hole 3, an annular inflatable air bag 4, a tube opening 5, a middle rope belt fixing band 6, a stomach tube 7, a closed inflatable joint 8, an oxygen hole 9, an air vent tube opening 10 and an upper rope belt fixing band 11.

Referring to fig. 1 and 2, the noninvasive positive pressure ventilation mask of the respirator comprises a mask body 1 in an arc shape, wherein the edges of two sides of the mask body 1 are provided with a rope belt fixing belt 2 and an upper rope belt fixing belt 11 which are fixed at four points, and the upper side of the mask body 1 is provided with a middle rope belt fixing belt 6 (the shape and the length are not limited) which is fixed at five points. A stomach tube inserting hole 3 and an oxygen hole 9 which penetrate through the lower side of the mask body 1, and an annular inflatable air bag 4 (with the size and the length not limited) with a stomach tube passing hole in the middle is lined on the wall of the stomach tube inserting hole 3. The inner side and the outer side of the stomach tube inserting hole 3 are provided with a convex pipe orifice 5, so that the annular inflatable air bag 4 is convenient to install stably.

An annular inflatable air bag 4 is arranged on the outer layer of the connection part of the stomach tube 7 in the mask body 1, a plastic thin tube and an airtight inflatable joint 8 are arranged outside a stomach tube insertion hole 3 of the annular inflatable air bag 4 exposed out of the mask body 1, the airtight inflatable joint 8 is connected with an injector, and the annular inflatable air bag 4 is filled with air and expands after the stomach tube 7 is inserted, so that no gap exists between the stomach tube 7 and the mask body 1, and air leakage is avoided.

The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
