Description

Tracheal cannula blocking device

Technical Field

The utility model relates to a medical supplies, concretely relates to tracheal cannula blocking device.

Background

Tracheotomy is a technique of incising the anterior wall of the neck trachea by an operation method, inserting a tracheal cannula to form an artificial airway, and solving the problem of dyspnea or asphyxia. When the patient has stable illness and the dependence on tracheotomy is relieved, the tube drawing can be considered. Before tube drawing, a patient needs to try to block the tube to help the patient recover the breath through the mouth and the nose. The common method for blocking the pipe is to block the pipe completely after the pipe is partially blocked. The foreign tracheal cannula has matched blocking devices, such as a blocking cap, a blocking plug and the like. However, in China, the tracheal cannula used clinically at present does not have a matched tube blocking device, common tube blocking materials comprise a cork, an eraser, a disposable syringe, an infusion apparatus, a disposable drainage bag connector and the like, the problems of poor disinfection, complex manufacturing and the like exist, part of materials have the risk of suffocation caused by a suction tracheal tube, and in addition, the problems that a single tube blocking device is not suitable for tracheal cannulas with different apertures, cannot meet the requirement of tube blocking in different times and the like exist.

Disclosure of Invention

An object of the utility model is to provide a simple structure, reasonable in design, convenient to use's tracheal cannula blocking device to prior art's defect and not enough.

In order to achieve the above object, the utility model adopts the following technical scheme: it comprises a large plugging cap and a small plugging cap; the large plugging cap and the small plugging cap are connected through a flexible connecting piece; the large plugging cap can be in sleeve connection with the tracheal cannula; the big plugging cap is provided with a vent hole; the small plug cap is connected with the vent hole in a matching way;

furthermore, the large plugging cap comprises a large plugging cap cover with elasticity and a large plugging cap top; the large plugging cap cover is of an annular structure as a whole; the top of the large plugging cap is arranged at the top of the large plugging cap cover; the vent hole is arranged in the middle of the large plugging cap top;

furthermore, the small blocking cap comprises a small blocking cap edge and a small block arranged at the bottom of the small blocking cap edge; the small plug can be inserted into the vent hole.

After adopting above-mentioned structure, compare with prior art, a tracheal cannula blocking device, have following advantage:

1. the tracheal cannula blocking device is not inserted into the tracheal cannula, only covers the periphery of the tracheal cannula, is safe to use, and does not have the danger of asphyxiation caused by sucking the tracheal cannula;

2. the large plugging cap has elasticity, is suitable for tracheal tubes of different models, and has wide application range;

3. the small plugging cap is opened to test plugging of the tube, and the small plugging cap is closed to fully plug the tube, so that the safety of a patient is effectively ensured, and the tube drawing rate is improved;

4. the large blocking cap is tightly connected with the air pipe sleeve, so that the situation that the pipe blocking device is coughed out to cause pipe blocking failure can be prevented or reduced;

5. the tracheal cannula blocking device is sterilized after production and is packaged separately, so that the tracheal cannula blocking device meets the aseptic requirement, is safe and convenient, has low production cost and has wide clinical application prospect.

6. Simple structure, reasonable arrangement and low manufacturing cost.
