Endotracheal tube with adjustable frontend curvature

Abstract

The invention relates to a tracheal tube capable of adjusting the curvature of the front end. The invention adopts the technical proposal that: the curvature of the front end of the tracheal tube is set to be 110 DEG; the front end of a tube core is arranged inside the front end of the tube and the rear end of the tube core is connected with a spring which is sleeved on a telescopic rod; and the other end of the spring is supported on a tail step of the telescopic rod. The tracheal tube solves the problems in a fiberscope of the prior art that: the price is expensive; and additional apparatuses such as a tailored laryngoscope and so on are adopted, thereby affecting the visual field of doctors and being unfavorable for the subsequent operation. The tracheal tube is suitable for common anddifficult tube insertion which can be completed by one person within a few minutes without the necessity of special training and experience, and has good effect. Moreover, the tracheal tube is simplein structure, low in cost and convenient and reliable in use.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a trachea tube. Background technique [0002] An endotracheal tube is a necessary device for endotracheal intubation. The endotracheal intubation method is to expose the glottis with a laryngoscope under the condition of general anesthesia, muscle relaxation, hyperventilation and apnea of ​​the patient, and then put the endotracheal tube with a certain curvature (about 20 degrees) on the tube with a certain curvature. The core is inserted into the trachea by the glottis. Due to the height of the larynx, the shape of the epiglottis, the angle between the longitudinal axis of the oropharynx and the trachea in different patients, or the inability to fully expose the glottis due to developmental deformities or anatomical variations caused by trauma, it often leads to difficulties in tracheal intubation , Improper handling will threaten the life of the patient.

AI Technical Summary

Problems solved by technology

Due to the height of the larynx, the shape of the epiglottis, the angle between the longitudinal axis of the oropharynx and the trachea in different patients, or the inability to fully expose the glottis due to developmental deformities or anatomical variations caused by trauma, it often leads to difficulties in tracheal intubation , Improper handling will threaten the life safety of the patient

[0003] Before the present invention, in order to solve this problem, extra instruments were often used, such as a special laryngoscope, which can make the glottis better exposed, but affects the doctor's field of vision, which is not conducive to the following operations; Expensive, and the user must have considerable experience, otherwise it will cause greater harm to the patient

Difficult airways take a considerable amount of time, and endotracheal intubation must be performed within minutes or the patient's life may be at risk
