Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

A noninvasive ventilation decompression mask with sealed gastric tube access as shown in fig. 1 and fig. 2, comprising: a mask body 100. Specifically, the mask body has a nose bridge segment 110, cheek segments 120 and a chin segment 130 symmetrically distributed and flanked thereon. When a patient wears the noninvasive ventilation mask, the nose bridge section presses the nose bridge part of the patient, the cheek sections press the cheeks on two sides of the patient, and the lower jaw section presses the lower jaw part of the patient, so that a relatively closed space is formed between the nose bridge section and the face of the patient. And in order to make nasogastric tube be unlikely to receive the oppression of face guard body, the edge of the cheek section of one side of face guard body is inwards sunken to be provided with a draw-in groove 140, and this draw-in groove is not less than nasogastric tube's bore to nasogastric tube can put into. Meanwhile, a sealing air bag 150 is arranged on the inner side surface of the clamping groove. Specifically, the sealing air bag extends along the inner side surface of the clamping groove to ensure that the air bag can be uniformly expanded on the inner side surface of the clamping groove after being inflated. In addition, an air nozzle 160 is provided on the outer surface of the mask body and is in air communication with the air-tight bladder via a conduit 170. A check valve 180 is provided in the air tap. Specifically, the one-way valve is in one-way conduction from outside to inside. In the specific implementation process, the one-way valve can adopt a silica gel one-way valve, a top bead type one-way valve and the like.

As a further improvement of the above embodiment, in order to adapt to different nasogastric tube intubation positions (left nostril insertion or right nostril insertion), clamping grooves are concavely arranged on cheek sections on two sides of the mask body.

As a further improvement of the above embodiment, the nasogastric tube is better secured in the notch to prevent the inflated sealing balloon from squeezing out the nasogastric tube. The clamping groove is in a C shape with a closed opening.
