Oropharynx airway with air source connector

Abstract

The invention discloses an oropharyngeal airway with an air source joint, which is an integrated structure composed of a flat strip-shaped airway with a flange and an air source joint located on the top of the flange, wherein the airway is composed of a straight pipe section It is composed of a curved pipe section and a flange on the top of the straight pipe section. There are grooves on both sides of the ventilation cavity of the air channel; small holes are provided on both sides of the flange on the top of the straight pipe section; the air source joint is 15mm from the upper part. The conical joint and the lower intubation tube are formed, and the lower intubation tube is inserted and fixed in the straight pipe section of the airway; the opening width of the groove is smaller than the bottom width; the bottom end of the curved pipe section is an arc-shaped end. Beneficial effect: the side wall of the ventilation cavity can support the straight pipe section, so that the product has stronger anti-occlusion force. The gas source connector can be directly connected with the connector of the extracorporeal ventilator and the connector of the oxygen delivery tube for oxygen delivery; the sputum suction tube and the thin tubular medical consumables of the fiberoptic bronchoscope can be inserted into the throat of the patient through the groove. Secure the snorkel with straps threaded through the two small holes in the flange.

Description

technical field [0001] The invention relates to an oropharyngeal airway, in particular to an oropharyngeal airway with an air source connector, belonging to the technical field of medical devices. Background technique [0002] The oropharyngeal airway, also known as the oropharyngeal airway, is a non-tracheal tube airway. It is the simplest, most effective and economical airway assisting device. Opening the airway is widely used in major hospitals. The general oropharyngeal airway is a hard flat tubular artificial airway made of elastic rubber or plastic, which is curved, and its curvature is similar to that of the tongue and soft palate. Its structure is mainly composed of three parts: the flange, the tooth pad part and the curved airway body. The oropharyngeal airway produced on the market has some following deficiencies during clinical use: [0003] 1) Although the oropharyngeal airways produced on the market are easy to operate and use in clinical applications, their ...

AI Technical Summary

Problems solved by technology

[0003] 1) Although the oropharyngeal airway produced in the market is easy to operate and use in clinical applications, its function is single, and it can only form a smooth ventilation channel for the oropharynx to prevent suffocation caused by the tongue falling backward

In the treatment or recovery period, it is not only difficult to give oxygen, sputum suction, and anesthesia in emergency situations, but also needs to replace consumables. The operation is cumbersome, wastes time, causes discomfort to the patient, and is not conducive to treatment;

[0004] 2) The curved flat-tube airway body of the oropharyngeal airway currently on the market is easily bitten by the patient and deformed, and an additional bushing is required to support the nozzle, resulting in a complex structure

[0005] 3) The placement of the oropharyngeal airway will cause discomfort to the patient. If the oropharyngeal airway is not properly fixed, the pipeline will often protrude.

[0009] But the disadvantages: the structure is more complicated, and there are too many accessories. When it is inserted into the pipeline, the accessories will affect the use of the medical staff. After insertion, the airbag needs to be inflated, which is not conducive to the rapid rescue of patients

[0012] But the disadvantages: the oropharyngeal airway with a fixed belt, the fixed belt is long and drooping, which affects the operation of the medical staff when inserting the pipeline, and the patient's age and head circumference are different, the applicability of the fixed belt is not strong, and the use remains unchanged
