Trachea cannula core and preparation method thereof

Abstract

The invention provides a safe efficient trachea cannula core with simple operation and a preparation method thereof. The trachea cannula core comprises a guide point and a moulding tube core. The guide point is outwards extended from one end of the moulding tube core. The guide point is connected with the moulding tube core. The outer diameter of the trachea cannula core is less than the inner diameter of a trachea cannula. The trachea cannula core is placed in the trachea cannula. The length of the trachea cannula is less than the length of the trachea cannula core. The trachea cannula can bereplaced by the guide point of the trachea cannula core, so the front end is thinner in an intubation process, and more easily inserted in a trachea. A traditional intubation mode is changed, the thinner guide point is firstly inserted, and the trachea cannula is pushed in, so the process is safe and efficient. The moulding tube core is combined with the guide point, the guide function is guaranteed, and the moulding is kept as well. A human body is prevented from injuring by a metal. The process is safer, the operation is easy through the combination, the price is cheap, and the manufacturing is convenient.

Description

[0001] This invention is a divisional application of the Chinese invention patent application with the patent application number "201610162847.9" and the title "A tracheal intubation stylet and its preparation method" filed by the applicant on March 21, 2016, and its entire content incorporated into this application. technical field [0002] 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 [0003] 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...

Problems solved by technology

[0004] 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 tube can maintain the same shape as the shaped stainless steel wire, so that The endotracheal tube matches the physiological curvature of the upper airway of the human body. On the one hand, because the shape of the stainless steel wire is bent by the doctor's hands based on experience, it has a certain degree of randomness, and it is difficult to ensure that it is truly consistent with the physiological curvature of the patient's upper airway. On the other hand, since the stainless steel wire does not have a special fixing piece to match the endotracheal tube, the stainless steel wire and the endotracheal tube need to be operated by doctors separately. If the doctor does not cooperate tacitly, the front end of the stainless steel wire protruding from the front end of the endotracheal tube may injure the upper airway structure of the patient, or the front end of the stainless steel wire is far away from the front end of the endotracheal tube, so that the stainless steel wire cannot play its due role in shaping
