Novel tracheal catheter

Abstract

The invention relates to a novel tracheal catheter for clinically establishing an artificial airway. The head end of an existing catheter and an air bag section catheter are basically located on the same straight line, and the included angle formed by the head end of the catheter and the glottis plane is small or even parallel during intubation. After an epiglottis is exposed by using a laryngoscope during clinical intubation, the head end of a tracheal catheter is positioned near the glottis and cannot enter a trachea through the glottis, so that intubation is difficult, intubation injury is easily caused, and even serious hypoxia and death are caused. The catheter is connected with the catheter head end at an angle, the minimum included angle between the inner diameter center line of the catheter head end and the inner diameter center line of the catheter is an angle A, and the angle range of the angle A is 5-30 degrees. The problem that it is difficult to insert the catheter head end into the glottis and send the catheter head end into the trachea is solved, the angle between the catheter head end and the glottis plane is increased during intubation, the triangular guide strip and the catheter head end diagonal plane can be directly sent into the glottis, or the catheter head end diagonal plane is guided by the triangular guide strip to enter the glottis; the tracheal catheter is continuously pushed, and the catheter head end forms an angle at two positions, so that the catheter head end easily enters the trachea through the glottis. The novel tracheal catheter is simple and feasible in intubation operation, high in success rate and small in airway injury.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a novel tracheal tube for clinically establishing an artificial airway. Background technique [0002] After clinical tracheal intubation laryngoscopy reveals the epiglottis, the tip of the endotracheal tube is located near the glottis and cannot pass through the glottis, making intubation difficult, easily causing intubation injury, and even severe hypoxia and death. The fundamental reason is that the tip of the catheter and the catheter of the balloon segment are basically in a straight line, and the angle formed between the tip of the catheter and the glottis plane is small or even parallel during intubation. [0003] A variety of clinical reasons can lead to a smaller or even parallel angle between the tip of the catheter and the glottic plane during intubation. Videolaryngoscopy-guided orotracheal intubation, nasotracheal intubation, upper airway anatomy, or laryngoscopy revea...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the above-mentioned deficiencies, and provides a new type of tracheal tube, which increases the angle between the tip of the tube and the glottis plane during intubation, solves the problem of difficulty in inserting the tip of the tube into the glottis and difficulty in sending it into the trachea when intubation is difficult, and reduces the risk of intubation. Difficulty of intubation, easy intubation operation, easy to be mastered and accepted by clinicians, improve intubation success rate, and reduce intubation injury at the same time
