Description

Fixing device for trachea cannula

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a fixing device for a tracheal cannula.

Background

The trachea cannula is a technique that a special endotracheal tube is placed into a trachea through a glottis, can provide optimal conditions for smooth air passage, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like, and is widely used in medical operations such as clinical operation, anesthesia, emergency resuscitation and the like. The safe fixation of the oral tracheal catheter is a necessary guarantee for the effective ventilation of a patient through the tracheal intubation, at present, the patient is generally prevented from biting the trachea in a mode of placing a bite block and tying a belt after the intubation is successful clinically. For the trachea cannula which has the risk of tube drawing, the trachea cannula is effectively fixed for the second time by means of an adhesive tape or a small-sized tape, but the operation has a plurality of defects, firstly, the traditional bite block is usually made of hard plastics which are not easy to deform, the oral mucosa of a patient is easy to damage, and the risk of oral infection exists; secondly, the position and the tightness of the lace fixed by the bite block are determined only by experience, the bite block is easy to shift after the trachea cannula is fixed or the oral cavity is washed, or the fixing effect is not ideal due to the too wide lace elastic band; the tracheal catheter and the bite-block are fixed by means of an adhesive tape or a small-sized tape after the intubation is finished, the effect is poor, and even the trachea is taken off, so that the life and health of a patient are threatened; moreover, the operation is troublesome on secondary fixation, two persons are needed to complete the operation, and the medical work efficiency is reduced. There is a need for a tracheal intubation fixation device that is easy to operate and that stably fixes the endotracheal intubation to improve the efficiency of medical work.

SUMMERY OF THE UTILITY MODEL

The utility model provides a fixing device for a tracheal cannula, which realizes the efficient and stable fixation of the tracheal cannula by arranging a fixing wall, a fixing part, an opening and other parts on the fixing device.

In order to solve the above problems, the present invention provides a fixing device for an endotracheal tube, comprising:

the protective mouth is provided with a vent hole which penetrates through the protective mouth;

the fixing band is arranged at one end of the mouth protector;
