technical field

The utility model relates to the technical field of medical devices, in particular to a positionable bronchial catheter.

Background technique

A tracheal tube is a medical device that is inserted into a patient's trachea or bronchi to create a temporary artificial breathing passage for patients, especially patients who cannot breathe on their own.

The existing bronchial catheter fixation method is usually realized by squeezing the inner wall of the patient's bronchial mucosa through a balloon. This type of fixation method has great limitations and can only fix the end of the bronchial catheter. position, which will damage the mucous membrane and bring discomfort to the patient.

In addition, when the existing bronchial catheter is fixed with a balloon, the balloon will always compress the mucosa, and the extrusion area is small, resulting in poor blood flow, necrosis of tissue cells, and easy injury to the patient.
