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

Embodiment Construction

[0012] Such as figure 1 , figure 2 Shown:

[0013] The material of the tracheal tube 1 is the same as that of the prior art, and it is made of semi-soft plastic or polymer material. The front end of the tracheal tube 1 is made at an angle of 110 degrees in advance and fixed, but it can be adjusted and changed; The front end of the core 2 is set in the tracheal tube 1 and can be telescoped and moved freely in the tracheal tube 1; the rear end of the tube core 2 is connected to one end of the spring 3, the spring 3 is sleeved on the telescopic rod 4, and the front end of the telescopic rod 4 is in the The tube core 2 is fixedly connected. The end of the telescopic rod 4 has a protruding step 5, and the other end of the spring 3 rests on the protruding step 5. The diameter of the telescopic rod 4 is larger than the diameter of the tracheal tube 1; therefore, the front end of the telescopic rod 4 The top is outside the rear end of the tracheal tube 1; and the diameter of the step 5 ...

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 and difficult 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 simple in 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 tracheal catheter. Background technique [0002] The endotracheal tube is a necessary instrument for endotracheal intubation. Tracheal intubation is to expose the glottis with a laryngoscope under general anesthesia, muscle relaxation, hyperventilation and no breathing, and then place a tracheal tube with a certain curvature (about 20 degrees) in a certain curvature of the tube The core is inserted into the trachea by the glottis. Different patients can not fully expose 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, or the anatomical variation caused by the patient's developmental deformity or trauma, which often results in difficulty in intubating the trachea , Improper handling will threaten the lives of patients. [0003] Prior to the present invention, in order to solve this problem, addi...
