Bougie type tracheal catheter

Abstract

Disclosed is a bougie type tracheal catheter. Due to the fact that a video laryngoscope is popularized, exposure of a glottis is improved, great difficulty is caused by tracheal intubation frequently, and a tracheal catheter is difficultly aligned to the glottis and then difficultly fed into a trachea. When the glottis is exposed by the indirect laryngoscope, the anteflexion bending of a laryngeal part air way is increased, a lower glottis air way forms retroflexion bending to form an S-shaped channel. The bougie type tracheal catheter is characterized in that a cylinder at the tip end of the catheter and the whole catheter are molded in advance in a hockey ball rod shape, and the revolutionary outward-turning 180-degree catheter feeding method is adopted. After the bougie type head end is inserted into the glottis forwards and upwards, the catheter is turned outwards while being pushed into the trachea. When the marking line in the middle of the back of the catheter body is rotated to be the position over the catheter body, a rear annular marking line is at the position of the glottis, and the tracheal catheter is fixed at the position. At the moment, the front bending of the catheter just fits the retroflexion dissection bending of the lower glottis air way. Accordingly, the bougie type tracheal catheter facilitates intubation and feeding, the success rate is high, and damage to the air way is avoided.

Problems solved by technology

[0002] When conventional laryngoscopy is used clinically for tracheal intubation, insufficiency of the glottis is often encountered. At this time, conventional intubation of the tracheal tube is very difficult or easy to cause damage, or even severe hypoxia and death

In order to solve the exposure of the glottis, indirect laryngoscopy (video laryngoscope) is gradually becoming popular in clinical practice, which has significantly improved the exposure of the glottis. However, when the video laryngoscope exposes the glottis, the forward curvature from the mouth to the glottis increases. The catheter is difficult to reach the glottis due to insufficient curvature of the front segment, which often causes more difficulties for endotracheal intubation. Clinically, the glottis can be seen but difficult to insert the endotracheal tube frequently occurs, and even leads to death

The current clinical countermeasures often use stylet or intubation bougie to assist in guiding tracheal intubation. Although it can solve part of the intubation, there are the following clinical problems: 1. The endotracheal tube can be aligned with the glottis, but it is difficult into the trachea

In this way, even if the endotracheal tube enters the glottis and then reaches the front wall of the upper end of the trachea, it is difficult to continue to push into the trachea, which is more likely to cause damage to the tracheal wall or cause accidents if the tube is unintentionally taken out when the laryngoscope is withdrawn

2. The bougie-guided method of intubation requires the tip of the endotracheal tube to fit closely with the bougie so that it can be easily introduced into the glottis without causing damage. At present, the tip of the conventional endotracheal tube opens to the side, and the bougie and the tip of the endotracheal tube Can easily form bifurcations that can obstruct cannulation and cause injury

3. The stylet is hard and can only assist the catheter to align with the glottis, but cannot help the catheter enter the trachea. At the same time, there are complications such as airway damage or accidental removal of the catheter when the stylet is withdrawn.
