Description

A sputum-suction tracheotomy sleeve

technical field

The utility model relates to the technical field of clinical medical instruments, in particular to a phlegm-absorbing tracheotomy sleeve.

Background technique

Tracheotomy is a common operation that cuts the cervical trachea and puts a metal tracheal cannula or a silicone cannula with a balloon to relieve dyspnea and respiratory dysfunction caused by laryngeal origin or secretion retention in the lower respiratory tract. After the tracheotomy, the tracheostomy catheter needs to be connected to the ventilator for mechanical ventilation. When the ventilation treatment is stopped, the airbag of the tracheostomy catheter in the trachea will be deflated and temporarily left in the trachea. At this time, the patient passes the tracheostomy catheter Inhale air or oxygen. However, at present, when the patient’s condition improves and the tracheal tube needs to be pulled out, two methods are usually adopted clinically: first, pull out directly and seal and fix the tracheotomy wound with a butterfly tape. If the patient’s condition recurs and mechanical ventilation is required again , will lead to secondary tracheotomy and increase the pain of the patient; second, before extubation, try to block the tube first, that is, use a piston to block the opening of the tracheotomy tube, and the patient will inhale and exhale through the mouth and nose, so that although The risk of secondary incision is avoided, but after the trachea is blocked, the trachea catheter is placed in the trachea to form an artificial narrowing of the airway, so that the patient will have difficulty breathing due to the small gap, causing discomfort to the patient.

In summary, the prior art has the following disadvantages: when suctioning upward, the suction tube on the side of the cannula is easy to cause insufficient suction due to its fixity and non-stretchability, and the suction tube is easy to block ( The secretion from the patient's mouth and throat sinking to the air sac is large, viscous, or aspiration of granular or massive foreign bodies). Due to its irreplaceability, the suction tube on the side of the cannula can easily lead to the retention of bacteria and viruses, causing bronchitis and persistent lung infection. Can not improve the success rate of tracheal blockage. When the cannula is blocked, airflow can only enter and exit the main bronchus from the periphery of the cannula.
