Oral cavity opener, tracheal intubation auxiliary device thereof and use method thereof

Abstract

The invention discloses an oral cavity opener and a trachea cannula auxiliary device and a using method thereof. The oral cavity opener comprises tooth sockets matched with an upper gum structure and a lower gum structure respectively; the two tooth sockets are connected through a plurality of supporting assemblies, each supporting assembly supports the two tooth sockets to be attached to the upper gum and the lower gum respectively, and a tongue depressor is arranged on the tooth socket corresponding to the lower gum. The tongue depressor is of an arc-shaped structure matched with the tongue, the front end of the tongue depressor extends towards the throat and covers the epiglottis in a pressing mode, firstly, the supporting assembly is combined with the tooth socket to open the upper gum and the lower gum, the oral cavity is completely opened, then the tongue depressor covers the tongue in a pressing mode, the throat of the human body is exposed, and the front end of the tongue depressor covers the epiglottis in a pressing mode; therefore, openings of the esophagus and the trachea of a human body are completely exposed, plugging of the esophagus and insertion of a trachea cannula are facilitated, the tongue depressor is provided with baffles used for supporting cheek parts on the two sides in the oral cavity respectively, the baffles are fixed to the edges of the two sides of the tongue depressor respectively, and the opening effect of the oral cavity is further guaranteed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an oral opener, an auxiliary device for tracheal intubation and a use method thereof. Background technique [0002] Endotracheal intubation is a method of inserting a special endotracheal tube through the oral cavity or nasal cavity and into the trachea or bronchus through the glottis. It is an important measure to rescue patients with respiratory dysfunction and a basic operation for anesthesia. However, emergency rescue patients often have full stomach, and emergency tracheal intubation often causes reflux and aspiration. If it is not treated in time, it will cause acute airway obstruction and other serious complications of the lungs, which are currently the most common cause of death for patients under general anesthesia. One of the important reasons. At present, the exposure method of tracheal intubation can only rely on the anesthetist to position the patient and use a video ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the above-mentioned technical problems, provide an oral opener and its auxiliary device for tracheal intubation and its use method, before inserting the tracheal intubation tube into the human trachea, the oral cavity can be completely opened, and the tongue and epiglottis can be pressed. The trachea and esophagus of the human body are completely exposed, and it can prevent gastric reflux aspiration and clean up the contents of the oral cavity and throat in time, which solves the problem that patients cannot effectively prevent reflux aspiration in the prior art
