Umbrella-shaped cuff trachea cannula

Abstract

The invention provides an umbrella-shaped cuff trachea cannula. A closed cuff is bonded to the periphery of a section of trachea cannula, a cuff air injection hole is formed on the trachea cannula part of the cuff section and communicated with an air injection tube, the air injection tube extends out of the trachea cannula wall and is connected to an air release valve, the air release valve is communicated with an air bag through a conduit, and the upper part of the air bag is connected with an air injection port in which an air injection valve is arranged. The front part of the cuff is an umbrella-shaped wall, the front side of the umbrella-shaped wall is connected with a limit net, and the limit net is provided with a plurality of limit meshes. Compared with the conventional cuff trachea cannula, the umbrella-shaped cuff trachea cannula can automatically adjust the pressure between the cuff and the human trachea wall so as to prevent over-high pressure from destroying the trachea mucosa and prevent air leakage. Moreover, the umbrella-shaped cuff trachea cannula is convenient and smooth to plug and pull, and is suitable to be used as a trachea cannula and a trachea cutting cannula in the field of medical equipment.

Description

technical field [0001] The invention provides an appliance in the field of medical instruments, in particular an umbrella-shaped cuff endotracheal tube. Background technique [0002] Tracheal intubation is a device inserted into the human trachea for ventilation during medical procedures. Its structure is: a closed cuff is sheathed on the periphery of the intubation tube, and an air injection tube is communicated with the closed cuff. Most of the currently used cuffs are low-pressure, high-capacity airbags. During use, in order to prevent air leakage, a certain amount of gas must be injected into the cuff to generate an airway pressure greater than that during ventilation. The effect of closing the airway. This pressure will undoubtedly act directly on the tracheal mucosa. If the pressure is small, air leakage is prone to occur. However, if the pressure is too high and the compression time is too long, the serious consequences of ischemia and necrosis of the tracheal muco...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the shortcomings of the existing tracheal intubation, the present invention provides an umbrella cuff endotracheal intubation

By changing the shape of the cuff and the setting of the cuff limit net and setting the deflation valve on the gas injection tube of the cuff, the intubation solution solves the technology of automatically adjusting the moderate compression force between the cuff and the human trachea wall and sealing the airway through the airway pressure question
