Double-airbag trachea cannula

Abstract

The invention relates to the technical field of medical instruments, and discloses a double-airbag trachea cannula. The double-airbag trachea cannula is characterized in that an airbag b is fixedly arranged in a catheter in a sleeving mode, the lower side of the airbag b is fixedly connected with a connecting tube a, the connecting tube a is fixedly connected with an airbag a, annular airbags are fixedly mounted on the inner wall of the connecting tube a, the inner walls of the annular airbags are attached to each other, a supporting strip is fixedly installed on the inner wall of the connecting pipe a, a movable column is movably connected to the supporting strip in a sleeving mode, a vent groove is formed in the lower side of the movable column, after the airbag a is attached to a user airbag, air continues to be injected into the airbag a, and redundant air can drive a movable plate to move upwards so as to drive the movable column to move upwards to be inserted into inner rings of the annular airbags, therefore, the redundant air can enter the vent groove and then enter the airbag b from an air outlet, and after air injection is stopped, the elastic force of the annular airbag b can downwards extrude the movable column to return to the original position, so that the situation that the airbag a expands excessively to extrude a trachea of a user to damage the trachea of the user excessively is prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-balloon endotracheal intubation tube. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis, which is called endotracheal intubation. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. . [0003] At present, most tracheal intubation tubes are single airbags, and the airbag on the endotracheal intubation tube is used to support the device and seal the user's trachea to prevent the user from aspiration, so the airbag needs to be closely attached to the inner wall of the user's trachea. However, when there is too much gas in the airbag, it will cause the user's trachea to be compressed and damaged. The thickness of each patient's trachea is different, and some med...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a double-balloon endotracheal intubation, which can prevent the airbag a from over-inflating and squeezing the user's trachea due to excessive strength and damage to the The user's trachea and other advantages solve the problem that most endotracheal intubations are single airbags at present, and the airbag on the endotracheal intubation plays a role in supporting the device and sealing the user's trachea to prevent the user from aspiration. The inner wall is tightly fitted, but when there is too much gas in the airbag, it will cause the user's trachea to be compressed too much and cause damage, which is inconvenient for the user to use.
