Endotracheal intubation tool

Abstract

An endotracheal intubation tool includes a guide cannula. A conical sleeve port is formed in one end of the guide cannula. A guide wire handle is arranged in the guide cannula. A remaining needle cannula is connected with the conical sleeve port. A flexible guide wire is connected to the guide wire handle. The guide wire handle is pushed to enable the guide wire to penetrate through the remaining needle cannula, the remaining needle cannula is slightly connected with the front end of the guide cannula, and the guide cannula is held by the right hand. When the glottis is opened, the guide wire is quickly inserted into the trachea, the guide cannula enters the trachea along the guide wire via the glottis, and the guide wire is withdrawn after the guide cannula enters the trachea. The endotracheal intubation tool is simple in structure, easy and convenient to operate, high in success rate and good in repeatability.

Description

technical field [0001] The invention belongs to the technical field of intubation, and in particular relates to a tracheal intubation tool. Background technique [0002] Traditional mouse tracheal intubation methods can be roughly divided into two types: invasive intubation and non-invasive intubation. [0003] Invasive tracheal intubation is the method of tracheotomy. Although it is relatively simple, it is more traumatic to the animal, and this method may cause bleeding, tracheal obstruction or even tracheal tear, and the mortality rate of the animal is relatively high. etc. will affect the observation of the research results, and the repeatability is poor. [0004] The methods of non-invasive endotracheal intubation include blind intubation and direct vision endotracheal intubation: [0005] The blind insertion method requires repeated trial insertions, and the success rate of one-time intubation is low, which can easily cause throat damage and laryngeal edema, which is...

AI Technical Summary

Problems solved by technology

[0005] The blind insertion method requires repeated trial insertions, and the success rate of one-time intubation is low, which can easily cause throat damage and laryngeal edema, which is not conducive to the recovery of animals. Although the required equipment is simple, it requires high technical requirements for the operator, which is not conducive to mastering

[0006] Direct-viewing endotracheal intubation means illuminating the mouth of the animal with the help of an external light source, opening the mouth of the mouse, and pushing the tongue to expose the glottis. The glottis is narrow and the position of the glottis is high. When there is no guide intubation, due to the rapid opening and closing of the glottis, it is difficult for the catheter to enter the glottis. Improper force may cause damage to the throat or enter the esophagus by mistake. Some methods use the rigid needle core of the indwelling needle As a guide, its disadvantage is that the hard stylet may cause damage to the surrounding tissue when it cannot be inserted successfully at one time, causing bleeding, or the hard stylet may cause tracheal damage

The accuracy of direct vision intubation has improved, but it requires certain technical requirements for the operator. Repeated intubation can easily cause laryngeal edema, airway damage, increased secretions, and even animal death. The repeatability is poor.
