Adjustable reinforced tracheal catheter

Abstract

The invention discloses an adjustable reinforced tracheal catheter which belongs to the field of medical apparatus and instruments. The tracheal catheter comprises a soft catheter, a inflating pipe, a catheter wire and a spiral steel wire rope, wherein the soft catheter is opened at the front end and is hollow; the catheter wire is arranged in the inner cavity of the catheter; the spiral steel wire rope is arranged on the inner wall of the catheter and is used for supporting; a sleeve bag is arranged at the part close to the front end part of the catheter; the rear end of the catheter is connected with a flexible rod sleeve which is internally provided with a telescopic rod and a telescopic spring, and the telescopic rod is connected with the catheter wire and can move in the telescopic rod sleeve; and a catheter body is provided with an inflating cavity communicated with the inflating pipe. According to the adjustable reinforced tracheal catheter, the problem of unsmooth ventilation caused by the factor that a soft catheter is folded by extrusion is solved on the basis of the prior art, respiratory mucosa is not hurt, the flexibility maintenance of the front end of the catheter can be enhanced, and the operating efficiency and control force of a user on the catheter are greatly improved by cooperation of the telescopic rod and the telescopic spring.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an adjustable reinforced endotracheal tube. Background technique [0002] Endotracheal tube intubation is an important measure in the process of cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. The endotracheal tube intubation method is to expose the glottis with the help of a laryngoscope under the patient's general anesthesia, hyperventilation and apnea state, and then insert a catheter with a certain curvature into the trachea through the mouth under the action of a tube core with a certain curvature. Due to the height of the larynx, the shape of the epiglottis, or developmental deformities in different patients, the glottis cannot be fully exposed, resulting in difficulty in inserting the tracheal tube, and even seriously affecting the life of the patient. [0003] Existing tracheal tubes mostly use pure soft tubes such as silic...

AI Technical Summary

Problems solved by technology

Due to the height of the larynx, the shape of the epiglottis, or developmental deformities in different patients, the glottis cannot be fully exposed, resulting in difficulty in inserting the tracheal tube, which seriously affects the life of the patient

[0003] Existing tracheal tubes mostly use pure soft tubes such as silica gel and rubber, which are prone to tube extrusion and blockage during operation; the tube core can move freely in the tube, and the insertion process is not safe, which may hurt the patient's glottis or the trachea; in addition, it is difficult to insert a catheter with a certain curvature in the front section into the glottis, and the tube core is tough, and the catheter is not easy to form a curvature
