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.
