Referring to fig. 1 to 5, the noninvasive ventilator mask assembly includes a mask shell 100, a decompression pad 200 and a gastric tube 300, the mask shell 100 is provided with a ventilator interface 110, the end face of the mask shell 100 is provided with a mask pad 120, the mask pad 120 is provided with a gastric tube groove 121, the gastric tube groove 121 is filled with an elastic rubber plug 122, the gastric tube 300 can be clamped in the gastric tube groove 121, the gastric tube 300 is provided with a sealing rubber block 310, and the decompression pad 200 is arranged on the joint face of the mask pad 120 and the patient.

When the mask shell 100 needs to be used in cooperation with the gastric tube 300, the gastric tube 300 is clamped in the gastric tube groove 121, and after the gastric tube 300 is clamped in the gastric tube groove 121, the gastric tube groove 121 is filled with the elastic rubber plug 122 to seal the gastric tube 300 in a sealing manner, so that gas leakage in the mask is avoided. When the gastric tube 300 is clamped in the gastric tube groove 121, the sealing rubber block 310 on the gastric tube 300 is tightly attached to the outer side surface of the gastric tube groove 121, so that the sealing performance is further improved, and the possibility of air leakage is reduced. When the gastric tube 300 is not needed, the elastic rubber plug 122 can seal the whole gastric tube groove 121 tightly, and the normal independent use of the breathing mask is not influenced.

Present stomach tube includes the different model of multiple pipe diameter the utility model discloses in, stomach tube 300 adopts the mode of clamping in stomach tube groove 121, can be applicable to the stomach tube 300 of different pipe diameters size, can not appear because the pipe diameter is different and adorn the condition of not advancing or gas leakage, and the suitability is better.

The pressure reducing pad 200 is arranged on the joint surface of the mask pad 120 and the patient, so that the oppressive feeling of the mask pad 120 to the face of the patient can be reduced, and the problem of pressure damage to the face of the patient caused by using the breathing mask is reduced.

As shown in fig. 6 and 7, the decompression pad 200 includes a gauze layer 210, a sponge layer 220, an antibacterial layer 230 and an attachment layer 240, which are sequentially disposed, a glue film layer 250 is disposed on the attachment layer 240, the decompression pad 200 and the mask pad 120 are adhered together through the attachment layer 240, and an opening 260 corresponding to the gastric canal is reserved on the decompression pad 200.

In the past, when the breathing mask is used each time, a whole piece of pressure reducing paste is generally cut by medical personnel. Cut into the shape matched with the breathing mask, thus wasting time and labor. Also, during use, the pressure relief pad 200 is pressed against the face of the mask cushion 120 and the patient's face, primarily by the pressure of the wearer of the respirator. The pressure reducing pad 200 is prone to displacement or even falling off during use.

In the present embodiment, the pressure reducing pad 200 has a contour corresponding to that of the mask pad 120, and when the pressure reducing pad 200 is used, the adhesive film layer 250 on the surface of the attachment layer 240 is torn off, and the pressure reducing pad 200 is adhered to the mask pad 120 through the attachment layer 240. This eliminates the need to cut the cushion every time it is used, and the pressure reducing cushion 200 and the mask cushion 120 are tightly adhered together, and the pressure reducing cushion 200 is not displaced.

Wherein, gauze layer 210 is direct and patient's facial contact, not only the moisture absorption, also be difficult to damage patient's skin, and sponge layer 220 can effectual buffering respirator to patient's facial pressure, and antibiotic layer 230 then can effectually avoid the long-time ventilative bacterial growing that causes of patient's face, and effectual protection patient's facial skin reduces the patient and because of wearing respirator for a long time and the problem that the pressure nature harmd appears.

In this embodiment, the width of the pressure reducing cushion 200 is greater than the width of the abutting surface of the mask cushion 120, so that the pressure reducing cushion 200 can be adhered to the opposing surface of the mask cushion 120, and the two sides of the pressure reducing cushion 200 can be adhered to the two sides of the mask cushion 120, thereby improving the adhesion effect of the pressure reducing cushion 200. Preferably, the pressure reduction pad 200 is 1.2-1.5 times the width of the mask pad 120.

As shown in fig. 8, the mask cushion 120 is a silicone gasket, a silicone slot 123 is disposed on the surface of the mask shell 100 opposite to the silicone gasket, and the silicone gasket is movably connected to the end surface of the mask shell 100 through the silicone slot 123.

In this embodiment, the mask cushion 120 is a silicone gasket, which has good elasticity and sealing performance. The silica gel gasket is installed on the end face of the mask shell 100 through the silica gel clamping groove 123, and has the characteristic of simple assembly.

The mask shell 100 is provided with connection rings 130 at both sides thereof, and a headband 400 is provided between the two connection rings 130. The mask shell 100 is worn on the face of a patient by the head band 400, and the length of the head band 400 can be adjusted to meet the requirements of different patients.

In this embodiment, the headband 400 includes left and right sides, one end of which is connected to one of the connection rings 130, and the opposite ends of which are connected by a hook and loop fastener. The left side and the right side are pasted together by magic tapes, so that the length of the headband 400 can be conveniently adjusted, and the headband is convenient to wear.

In this embodiment, the sealing rubber block 310 has a strip shape, and the area of the sealing surface of the sealing rubber block 310 is not less than the opening area of the gastric canal 121. To ensure that the sealing rubber block 310 can cover the whole gastric canal 121 after the gastric canal 300 is clamped in the gastric canal 121.

Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
