Background

Tracheotomy is an important and effective measure for rescuing critically ill patients, a tracheal tube is usually required to be left for a period of time after tracheotomy, and when the state of illness of patients is stable, the respiratory function is recovered and the like, extubation is attempted. After full-blockage tube observation is carried out for 24-48h before tube drawing, the patient does not have discomfort such as unsmooth respiration and the like, and the blood and gas analysis result is normal, so that tube drawing can be carried out.

In the past, the tracheal cannula is generally plugged by a self-made small wooden plug, and the tracheal cannula is made of wood materials according to the inner diameter of a metal cannula, so that the difficulty is high, and the time is wasted; the manual production specifications are sometimes not uniform, some are larger, some are smaller, and the effect and time of the full-blocking pipe are influenced; the wooden plug or the rubber are placed in the metal sleeve, wood chips can be generated after friction, the smoothness of an air passage is affected, exogenous infection is caused, the wooden plug or the rubber is pressed hard to prevent the pipe plug from being separated, but a patient feels uncomfortable or even can feel pain when the wooden plug or the rubber is pressed hard to successfully plug the pipe, and the pipe plugging time is prolonged.

The traditional tube blocking method is to close the long-opened airway suddenly, and when the patient is found to be totally blocked in clinic, the patient feels oppression, rapid breathing frequency, even severe cough and dyspnea, and the implementation of tube blocking is affected by ejecting the blockage. In addition, during the tube blockage period, the patient can not expectorate sputum from the mouth, sometimes the patient still needs to pull out the articles blocked by the tube and suck the sputum in time, and if the conventional self-made small wooden plug or rubber plug is used, the use effect is very poor.

Although some pipe blocking devices made of silica gel materials are arranged at present, the pipe blocking devices are single in function, and the problems of insufficient oxygen absorption of an air pipe, air pipe drying and the like cannot be solved after the pipe is completely blocked.
