Multifunctional general anesthesia catheter crush injury prevention protection device frame

Technical Field

The utility model relates to a medical treatment auxiliary instrument technical field especially relates to a multi-functional general anesthesia pipe prevents pressing and hinders protection device frame.

Background

The trachea cannula is a technique that a special endotracheal tube is placed into a trachea through a glottis in the operation process and is called as the trachea cannula, and the technique can provide optimal conditions for unobstructed airways, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like. The emergency trachea cannula technology becomes an important measure in the process of cardio-pulmonary resuscitation and emergency treatment of critically ill patients accompanied with respiratory dysfunction. The trachea intubation is an important rescue technique commonly used in emergency treatment work and is one of the most widely, most effective and most rapid means in respiratory tract management. The tracheal tube must be accurately positioned and fixed, but if the tube is bent and blocked or slips down into the airway, serious consequences can be caused.

At present, patients who are treated in operating rooms of hospitals and general anesthesia or ICU often need to be provided with tracheal intubation (anesthetic gas or oxygen is input), and the tracheal intubation is generally made of soft plastic products and is easy to bend and deform to influence the conduction effect; in addition, the interface of the tracheal cannula and the threaded tube of the respirator is often required to be connected with cannula or sensing lines (leads) of equipment such as gas monitoring equipment, artificial nose equipment and the like, so that the lines of an operation or treatment field are complex; because patient's mouth is apart from breathing machine and is had certain distance, length longer, and the trachea cannula who connects the breathing machine can not fixed on its circuit, leads to trachea cannula often to fall to positions such as patient's face easily, can bring the interference for the patient performs the operation on the one hand, and other pipe, wire can be oppressed to the while, influence the normal clear of operation or treatment.

In the current common intubation operation process, a specially-assigned person is required to manually fix the tracheal intubation, the vertical angle is adjusted, the tracheal intubation is prevented from falling to the face of a patient as much as possible, or the face of the patient is prevented from being bent due to pressure. Therefore, a specially-assigned person is required to manually (handhold) support and fix the intubation trachea during the operation, the manpower is wasted, the operation of an operator is influenced due to the fact that the operator occupies more space in an operating room, and meanwhile, other pipelines on the operation site cannot be tidied and supported.

In order to solve the problem that the tracheal cannula falls, the Chinese utility model patent CN209827880U discloses a tracheal cannula bracket, which comprises an inflatable body, wherein magic tapes are fixedly installed at the bottom of the body, two brackets which are staggered and angled are arranged at the top of the body, and the surface of a bifurcation area between the two brackets is a rough surface; however, the support is attached to a patient body through the bottom magic tape, so that although the problem that the tracheal cannula is easy to drop is solved, the inflated trachea still presses the face of the patient and cannot be accurately fixed, and the problems of arranging, supporting and fixing other catheters and wires cannot be solved.
