Tracheostomy catheter and method of using the same

technical field

The invention relates to the technical field of medical devices, in particular to a tracheostomy catheter and a method for using the same.

Background technique

Tracheotomy is a common operation for incising the cervical trachea and placing a metal tracheal cannula or a silicone cannula with a balloon to relieve dyspnea and respiratory dysfunction caused by laryngeal or lower respiratory secretion retention. After tracheotomy, a tracheotomy tube is connected to a ventilator for mechanical ventilation. When the ventilation treatment is stopped, the balloon of the tracheotomy tube located in the trachea will be deflated and temporarily indwelled in the trachea. At this time, the patient will pass the tracheotomy tube. Inhale air or oxygen. When the patient's condition improves and the tracheal tube needs to be pulled out, two methods are generally adopted in clinical practice: first, directly pull out and seal the tracheostomy wound with butterfly tape. This leads to a secondary tracheotomy, which increases the pain of the patient; second, before extubation, try to block the tube, that is, use a piston to block the opening of the tracheostomy tube, and the patient completes inhalation and exhalation through the mouth and nose, which avoids the need for There is a risk of secondary incision, but the blocked trachea forms artificial airway stenosis because the tracheostomy catheter is placed in the trachea.
