Trachea cannula plugging device

Abstract

The invention discloses a trachea cannula plugging device. The trachea cannula plugging device comprises a cannula plugging device body, a ventilation hole channel is formed in the pipe plugging device body, and a control assembly used for controlling on-off of the ventilation hole channel is arranged in the ventilation hole channel. The control assembly comprises a valve element, an elastic piece, a pull rod and a limiting mechanism, a containing cavity matched with the valve element is formed in the pipe plugging device body, one end of the containing cavity communicates with the ventilation hole channel, and the other end of the containing cavity communicates with the movable hole. One end of the pull rod is connected with the valve element, the other end of the pull rod penetrates through the movable hole and extends out of the pipe plugging device body, the elastic piece is arranged in the containing cavity, one end of the elastic piece is connected with the valve element, and the other end of the elastic piece is connected with the cavity bottom of the containing cavity. And the limiting mechanism is used for limiting the movement of the pull rod. The valve element is controlled through the limiting mechanism, so that adjustment of a semi-blocked pipe and a full-blocked pipe is achieved, and effectiveness, leakproofness, safety and practicability of pipe blocking are guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a trachea tube stopper. Background technique [0002] For patients who have undergone tracheotomy, a ventilation tube will be inserted into the trachea. After the condition is stable, a tube plugging test must be performed before extubation. Generally, the ventilation tube needs to be semi-occluded for 24 to 48 hours first. If the patient coughs up sputum forcefully and has no dyspnea, it can be completely blocked for 24 to 48 hours. If the patient behaves well, the ventilation tube can be removed. [0003] At present, there are no tools specially used for semi-occlusion and full-occlusion experiments, which are usually made temporarily by doctors. Such occlusion devices have poor sealing effect and are not fixed firmly. Patients are easy to wash off the occlusion device when they cough violently. , so that the ventilation tube is completely unblocked, resulting in inaccura...

Problems solved by technology

[0003] At present, there are no tools specially used for semi-occlusion and full-occlusion experiments, which are usually made temporarily by doctors. Such occlusion devices have poor sealing effect and are not fixed firmly. Patients are easy to wash off the occlusion device when they cough violently. , so that the ventilation tube is completely unblocked, resulting in inaccurate experiments; and when switching between half-blocking and full-blocking, the blocking device is not easy to take out, and it is also inconvenient to adjust, which is very troublesome to use
