Description

A multifunctional general anesthesia catheter anti-crushing protective device holder

technical field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a multifunctional general anesthesia catheter anti-crushing protection device frame.

Background technique

Endotracheal intubation is a technique in which a special endotracheal tube is placed into the trachea through the glottis during the operation. Offer the best conditions. Emergency tracheal intubation technology has become an important measure in the process of cardiopulmonary resuscitation and rescue of critically ill patients with respiratory dysfunction. Tracheal intubation is an important rescue technique commonly used in emergency work, and it is one of the most widely used, most effective and fastest means in respiratory management. However, the endotracheal tube must be accurately positioned and fixed, but if the tube is bent and blocked or slips and falls into the airway, serious consequences will result.

At present, patients under general anesthesia or ICU receiving treatment in the operating room of the hospital often need endotracheal intubation (input of anesthesia gas or oxygen). In addition, the endotracheal tube and ventilator threaded tube interface often need to be connected to the intubation tube or sensing line (wire) of gas monitoring, artificial nose and other equipment, resulting in complicated surgery or treatment site lines; due to the patient's mouth There is a certain distance from the ventilator and the length is long. The endotracheal tube connected to the ventilator cannot be fixed on its line, which will easily cause the endotracheal tube to often fall on the patient's face and other parts. On the one hand, it will bring surgical pressure to the patient. At the same time, it may oppress other catheters and wires, affecting the normal operation or treatment.

Now the usual intubation operation process requires a special person to manually fix the tracheal intubation and adjust the vertical angle to avoid the tracheal intubation from falling on the patient's face as much as possible, or to avoid bending the patient's face and other places due to pressure. fold. Therefore, special personnel are required to manually (hand-held) support and fix the intubated trachea during the operation, which is a waste of manpower. It also affects the operation of the operator due to the large number of people occupying the operating room space, and at the same time cannot arrange and support other pipelines on the surgical site.

In order to solve the problem of tracheal intubation falling, Chinese utility model patent CN209827880U discloses a tracheal intubation bracket, which includes an inflatable body, the bottom of the body is fixed with Velcro, and the top of the body is provided with two staggered angled brackets. The surface of the bifurcation area between the two brackets is rough; however, the bracket is attached to the patient's body through the bottom Velcro. Although the problem of easy falling of the endotracheal tube is solved, the inflated trachea will still press on the patient's face. It cannot be accurately fixed, nor can it solve the problems of finishing, supporting and fixing other catheters and wires.
