Lengthened fracturing resistant and pressing resistant type trachea cannula with expansion end

Abstract

The invention discloses a lengthened fracturing resistant and pressing resistant type trachea cannula with an expansion end. The lengthened fracturing resistant and pressing resistant type trachea cannula with the expansion end comprises a trachea cannula body, one end of the trachea cannula body is a cannula front end, an opening is formed in the pointed part of the cannula front end, the opening is a smooth spoon shape, the other end of the trachea cannula body is enlarged gradually in diameter to form the expansion end, the expansion end is in matching screw connection with a cannula connector, an anti-leakage device is arranged at the cannula front end, an air inflating pipe communicated with the anti-leakage device is connected to one side of the trachea cannula body, a small hole is formed between the anti-leakage device and the opening, and a metal wire is embedded in a cannula cavity of the trachea cannula body. According to the lengthened fracturing resistant and pressing resistant type trachea cannula with the expansion end, due to the fact that the trachea cannula is lengthened, the fitness of the connection environment of the trachea cannula and a breathing pipeline under the situation that a patient is at a prone position under a general anesthesia condition is guaranteed, and the comfort of the patient is improved; the expansion end is arranged, the trachea cannula body is lengthened, the inner diameter of the cannula is enlarged at the same time, air passage resistance is not increased, and sputum can be sucked conveniently; furthermore, the steel wire in the trachea cannula spirally is arranged, twisting and wrinkling are prevented, the service life of the trachea cannula is prolonged, operation is simple, and manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-bending type endotracheal intubation tube with an extended belt and an enlarged end. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube and intubation tool into the patient's trachea through the mouth to perform endotracheal anesthesia or rescue the patient. It is the most reliable means to keep the upper airway unobstructed. Therefore, endotracheal intubation is widely used clinically. One end is inserted into the trachea through the mouth, and the other end is connected to the artificial ventilator. Establishing an artificial airway to solve the problems of ventilation and expectoration is a very important rescue measure. [0003] In the course of clinical treatment, it was found that the existing tracheal intubation, especially the children's tracheal intubation, is too short. The connection environmen...

AI Technical Summary

Problems solved by technology

[0003] In the course of clinical treatment, it was found that the existing tracheal intubation, especially the children's tracheal intubation, is too short. The connection environment between the intubation tube and the patient's breathing circuit is not loose, which makes respiratory management difficult, and the efficiency of expectoration is relatively low, which affects the patient's respiratory management to a certain extent
