Description

Disposable trachea cannula inner limiting device

Technical Field

The utility model belongs to the technical field of trachea cannula technique and specifically relates to a stopper in disposable trachea cannula.

Background

The technology of placing a special endotracheal tube into the trachea through the glottis is called trachea intubation, and the technology can provide optimal conditions for smooth air passage, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like.

At present, the trachea cannula is adopted to keep the airway unobstructed in plastic surgery, such as nasal plastic surgery, oral surgery of five sense organs, such as vocal cord polyp, tonsil and other surgeries. However, in the above type of operation, since the surgeon needs to operate on the head and face, the endotracheal tube cannot be fixed by a bite block or an adhesive tape, and the tube is easily slipped out, which causes serious ventilation obstruction and even death. At present, a 'rubber cloth type inner limiter' is manufactured manually by winding and wrapping a plurality of layers of thick rubber cloth on the periphery of a conduit. However, the method has three disadvantages: firstly, the adhesive tape and the adhesive tape are exposed in the air and cannot be disinfected, and the adhesive tape are directly wound and placed in the oral cavity, so that the possibility of iatrogenic infection exists; secondly, the adhesive tape wound for a certain number of turns is time-consuming and labor-consuming, and is not beneficial to improving the working efficiency of an anesthesiologist; thirdly, the rubber cloth type inner limiting stopper is also the most important, because the rubber cloth type inner limiting stopper must pass through the mouth opening cracks of the upper and lower rows of teeth when the trachea is intubated, if the rubber cloth type inner limiting stopper is too thick, the rubber cloth type inner limiting stopper is difficult to be plugged into the oral cavity of a patient to complete the trachea intubation; if it is too thin; the embarrassment of the intraoperative tubular catheter falling out of the mouth can occur.
