Description

Endotracheal intubation tube core and endotracheal intubation tube

technical field

The utility model belongs to the field of medical anesthesia, in particular to a tracheal intubation tube core and a tracheal intubation tube.

Background technique

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 laryngoscope to assist the laryngoscope to lift the mandible, which can expose the glottis, so that the tracheal intubation can be placed. But in many cases, due to anatomical relationship, the glottis is difficult to expose, that is, it is difficult to see the glottis or only the edge of the glottis, or only the epiglottis or part of the epiglottis, or even The epiglottis cannot be seen. And the preoperative visit work sometimes cannot accurately judge the height of the glottis. Difficult airway is often discovered after laryngoscopy is used to provoke.

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. During the guiding process, it is necessary to avoid prolapse; third, during the guiding process, a non-invasive environment is required to reduce damage; fourth, during the blind operation, 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.
