Preferably, the bottom of fixing base is through the attached fixed to attached to the people department of pasting near both ends strip, paste the strip and be used for fixing to both sides nosewing respectively and be parallel to each other in the length direction.

The two adhesive strips are parallel to each other, which means the position relationship between the adhesive strips in the natural state of the flat-open fixing base.

Preferably, the patch is applied to the concave surface of the fixed seat facing the nose.

Preferably, the nasopharynx air duct is provided with a respiratory terminal carbon dioxide monitoring head and an oxygen supply monitoring head.

The plug is arranged outside the elbow, so that the position of the elbow in the nasal cavity can be further fixed while the nasal cavity is plugged. The form of the clamping head can play a role in fixing the nasopharynx air duct and the nasal obstruction, and the problems of injury and oxygen supply caused by the displacement of the nasopharynx air duct or the nasal obstruction are avoided.

The fixing band is fixed at the positions of the head circumference or the ears or the neck by encircling or binding, and the general positioning of the fixing seat is realized.

Through the setting of auxiliary hole, prevent that elbow front end main gas outlet from being blockked up by the secretion and the condition emergence of unable oxygen suppliment provides reserve oxygen suppliment passageway for oxygen system.

The nasal plug is matched with the nasopharynx air duct, so that the full utilization of oxygen supply can be realized, and the waste of ineffective oxygen supply is reduced.

The arrangement of the sticking strip firmly forms the relative accurate positioning of the fixed seat and the nostril, and further avoids the separation position of the nasopharyngeal airway on the fixed seat.

The beneficial effects of the utility model are that can realize the effective fixed of nasopharynx air vent, easy operation, the medical staff of being convenient for uses.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

A nasopharyngeal airway fixture as shown in fig. 1 to 3, comprising a nasopharyngeal airway 1 and a fixture base 2; the tail part of the nasopharyngeal airway 1 is communicated with an oxygen supply pipeline 3 of a breathing machine, the top of the nasopharyngeal airway 1 is provided with an elbow 11 for penetrating into the nasopharynx, and the elbow 11 is convexly provided with a plug 111 for plugging the nasal cavity; the front end side wall of the elbow 11 is provided with an auxiliary hole 112 for guiding out oxygen. The nasal plug 5 is used for blocking the nostril at the other side, and the nasal plug 5 is connected to the tail part of the nasopharyngeal airway 1 through a rope 51.

The bottom of the fixed seat 2 is a facing for attaching to the middle of a person, and the top of the fixed seat 2 is provided with a clamping head 21 for fixing the nasopharyngeal airway 1; the fixed seat 2 is a concave surface matched with the nose shape towards the nose side. Specifically, the bottom of fixing base 2 is attached through two near two sticky strips 22 of both ends and is fixed to attached to the person in the department, sticky strip 22 is used for fixing to both sides nosewing respectively and is parallel to each other on the length direction. Patch such as cooling oil is laid in the concave surface of the fixed seat 2 facing the nose side.

The specific form of the clamping head 21 is an elastic U-shaped clamping groove matched with the elbow 11. The fixing device further comprises a fixing belt 4 for fixing the head, and two ends of the fixing belt 4 are respectively connected with two ends of the fixing seat 2 through hanging rings 41 in an adapter mode. The fixing band 4 is a flannelette band, and one side of the fixing band facing a user is provided with a flexible antiskid projection 42.

The nasopharyngeal airway 1 is provided with a carbon dioxide end of breath monitoring head and an oxygen supply monitoring head (not shown in the figures, but the structure can be understood by those skilled in the art).
