Trachea cannula core and preparation method thereof

Abstract

The invention provides a trachea cannula core and a preparation method thereof. The trachea cannula has the advantages that the operation is simple, the safety is realized, and the efficiency is high. The trachea cannula core comprises a guide tip end and a moulding cannula core, wherein the guide tip end extends outwards from one end of the moulding cannula core; the guide tip end is connected with the moulding cannula core; the outer diameter of the trachea cannula core of a trachea cannula is smaller than the inner diameter of the trachea cannula; the trachea cannula core is arranged in the trachea cannula; the length of the trachea cannula is smaller than the length of the trachea cannula core. The trachea cannula core has the advantages that the guide tip end can replace the trachea cannula, the front end is thinner in the intubation process, and the guide tip end is easily inserted into a trachea; the traditional intubation type is changed, the thinner guide tip end is firstly inserted, and then the trachea cannula is pushed, so that the safety is realized, and the efficiency is high; by combining the moulding cannula core and the guide tip end, while the guide function is guaranteed, the moulding is maintained, the injury to the human body by metal is avoided, more safety is realized, the operation is easy, the price is low, and the manufacturing is convenient.

Description

technical field [0001] The invention belongs to the field of medical anesthesia, and in particular relates to a tracheal intubation stylet and a preparation method thereof. Background technique [0002] Endotracheal tubes have been used more and more widely as an essential device in the anesthesiology department, emergency department and laryngology department of the hospital. Since the endotracheal tube is made of plastic, which is relatively soft and not rigid enough, endotracheal intubation is an operation that every anesthesiologist performs almost every day. Endotracheal intubation refers to the endotracheal intubation, which is composed of a cannula and a stylet, is inserted into the patient's trachea through the patient's mouth, pharynx, and larynx after the patient's consciousness disappears during general anesthesia. Mechanical Ventilation. Due to anatomical factors, everyone's mouth and throat will not be in a straight line, so it is necessary to use a laryngosco...

Problems solved by technology

[0003] In the actual clinical work, there will be several problems: First, metal shaping is required to conform to the characteristics of the human body, because the angle of bending based on experience alone may not be suitable. Usually, the edge of the glottis can only be seen A small angle is required, but the angle required is relatively large when the glottis cannot be seen, and the angle of the prepared stylet is not suitable, which may easily lead to failure of intubation; second, it needs to fully enter the trachea. Avoid prolapse during the guiding process; third, a non-invasive environment is required to reduce damage during the guiding process; fourth, during blind manipulation, the front end of the guiding needs to be thin enough to accurately enter the trachea

In order to solve this problem, in the prior art, doctors use stainless steel wires to shape and sterilize according to the characteristics of the patient's upper airway and insert them into the endotracheal tube, so that the endotracheal tu
