Description

A fixed bracket for tracheal cannula

technical field

The utility model relates to a fixing bracket for a tracheal sleeve.

Background technique

When a critically ill patient cannot breathe normally after surgery, the trachea needs to be cut and a tracheal cannula inserted to help the patient breathe. The tracheal cannula needs a fixed column. Currently, the fixation method used in clinical tracheostomy patients is to use cotton ropes on both sides of the tracheal cannula. The cotton ropes on both sides are long on one side and short on the other side. The long side is wrapped around the back of the neck to the other side. One side is tied in a knot. However, because the ventilator pipeline is long and heavy, the tracheal cannula will deviate from the neutral position as soon as it is stretched, which may cause pain in the patient's air incision and increase the patient's pain. This can lead to an enlarged fistula, causing saliva and sputum to leak out of the gas incision, resulting in redness, dermatitis, or infection of the gas incision skin.
