Description

A kind of tracheal casing pipe ventilation test cord

Technical field

This utility model relates to medical test cord field, especially relates to a kind of tracheal casing pipe ventilation test cord.

Background technology

At present, in the clinical care of tracheal casing pipe, the method of the ability of test patient autonomous respiration is mainly stopped up tracheal casing pipe by cotton balls (or other tampers), and this method has three defectives, and first: be easy to make cotton balls (or other tampers) to drop in trachea; Second: during each test ventilation, all will prepare new cotton balls (or other tampers); The 3rd: during operation, step is very loaded down with trivial details.

Summary of the invention

In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of plug is connected on handle and can come off, the tracheal casing pipe ventilation test cord that plug also needn't be changed.

This utility model takes following technical scheme to realize: a kind of tracheal casing pipe ventilation test cord, it is comprised of plug, pore, handle, catch, fixed plug and connection chain, described plug is connected with described handle by described connection chain, there is described pore described handle top, described handle below is equipped with described catch, and described fixed plug is installed below described catch.

Described plug is connected with described handle by described connection chain.

Described fixed plug is stepped design.

The utlity model has in sum following beneficial effect: plug of the present utility model can be fixed on and be unlikely on tracheal casing pipe to drop in trachea, only need plug is pulled up or can be produced the effect of test beyond the Great Wall, plug can be tested repeatedly, needn't change, the stepped design of fixed plug goes for the tracheal casing pipe of three kinds of dimensions.
