Painless gastroscopy airway management system

Abstract

The invention discloses a painless gastroscopy airway management system which comprises a tooth cushion component and a fixing belt, wherein the tooth cushion component comprises an internal support shell and an external silicone gasket in match; the main body of the support shell is a cylinder of which the cross section is a long circle; a flanging is arranged at the outer end part of the cylinder; fixing belt holes are formed in both ends of the flanging; the silicone gasket is mounted on the cylinder in a sleeving manner; the length of the cylinder ranges from the outside of a human lip tothe inside of a mouth; an inner fixing sleeve is arranged on one side inside the cylinder; a part outside the fixing sleeve inside the cylinder is a gastroscope insertion area; a plurality of pipelineclamping convex ribs are arranged on the inner surface inside the inner fixing sleeve; and an airway component penetrates through the inner fixing sleeve and extends into a throat smooth airway alongwith swallowing. Since a clamping sleeve of an air through pipeline and the gastroscope insertion area are specifically arranged inside the tooth cushion component, the two channels are not mutuallyaffected, and the breath flow of a patient is not affected in gastroscopy. The airway component and the tooth cushion component are two independent components in match, and can be used independently or used together.

Description

technical field [0001] The invention relates to the technical field of medical detection auxiliary devices, in particular to a painless gastroscopy airway management system. Background technique [0002] Painless gastroscopy is to give a certain dose of short-acting anesthetic through veins first, to help patients quickly enter a state of sedation and sleep, complete gastroscopy without consciousness, and wake up quickly after the examination. After anesthesia, many patients, especially obese patients and patients with sleep apnea, will suffer from severe airway obstruction due to the back of the tongue and the relaxation of oropharyngeal muscles, and even cannot ventilate, resulting in insufficient oxygen supply and decreased oxygen saturation. Part of the airway obstruction can be resolved by lifting the mandible, but some patients still need the intervention of upper airway ventilation tools to relieve it. When the hypoxia is severe, it may even threaten the life of the p...

AI Technical Summary

Problems solved by technology

However, the ventilation tube inside the existing conventional oropharyngeal airway is too small to allow the gastroscope to pass through, so it cannot be performed at the same time as the gastroscopy, and it cannot be inserted when the patient is awake because it will cause gag reflex.

[0004] 2) The emerging tools have not completely solved the problem In order to solve the above problems, some people have made an oropharyngeal airway that can pass through the gastroscope, which solves the problem of airway obstruction to a certain extent, but there are also many shortcomings

a During use, it was found that under ideal conditions, the gastroscope directly faces the opening of the glottis and esophagus after passing through the oropharyngeal airway, and it will not be possible to explore the condition of the oropharynx and larynx

Moreover, it is not flexible enough to use. If such an oropharyngeal airway is not placed before the examination, once the airway is blocked during the examination, the gastroscope must be wit...
