Description

Improved tracheotomy tube

Technical Field

The utility model relates to the technical field of tracheal tubes, in particular to an improved tracheotomy tube.

Background

Because of the need of illness, ICU patients often need to establish an artificial airway for tracheotomy to ensure the smoothness of the respiratory tract of the patients, and the patients often need to carry out oxygen inhalation therapy, and oxygen inhalation is an effective measure for correcting hypoxemia. After the trachea is cut, the opening of the tracheal cannula becomes an important passage for oxygen to enter the airway, so that the effective connection between the tracheal cannula and the oxygen inhalation tube is the key for ensuring the smoothness of oxygen inhalation. In Intensive Care Unit (ICU), 20% of critical patients in hospital need tracheotomy, patients with early onset of tracheotomy often have aggravation of cervical edema and late edema decline, and patients with long-term indwelling tracheotomy often have complicated formation of intratracheal polyp. If the catheter fixing band can not be adjusted in time and the treatment of the polyp in the trachea is often seriously damaged. As a result of the study, it was found that patients with ICU indwelling tracheostomy tubes for long periods are often accompanied by polyp formation in the airways, leading to airway obstruction.

The existing lengthening type tracheotomy tube can be properly lengthened (about 1-2cm) compared with the traditional tube, so that the tracheotomy tube can cross the polyp position, the blockage of the air passage is relieved, and the smoothness of the air passage is kept.

However, the existing elongated catheter cannot solve the problem of polyp formation at the far end of part of the airway, once polyp blockage at the far end of the airway occurs, when the elongated catheter cannot cross the polyp, a better substitute tool cannot be found in an emergency, and the life of a patient is endangered. And the lengthened guide pipe is not arranged in an emergency state or a primary hospital, thereby bringing great hidden danger to rescue.

Therefore, it is necessary to design a new technical solution to comprehensively solve the problems in the prior art. In view of the above, there is a need to design an improved tracheostomy cannula that overcomes the above-mentioned technical problems.
