Prevent hydrops gas tube intubate

Technical Field

The application relates to the technical field of tracheal intubation design, in particular to an anti-hydrops tracheal intubation.

Background

In medical work, when a patient fails to breathe spontaneously or the respiratory tract is blocked, an endotracheal intubation is required to give emergency treatment to the patient. The trachea cannula is a hand bundle which is used for inserting a special plastic tube into the respiratory tract of a patient to be communicated with the lung, introducing oxygen into the lung and outputting carbon dioxide.

In the prior art, endotracheal tubes generally comprise a trachea, a sputum aspirator tube and a cuff. Wherein, the cuff is arranged on the outer wall of the trachea and surrounds the outer wall for a circle. The cuff expands and swells when inflated and is used for sealing the inner wall of the respiratory tract. The orifice of the sputum sucking tube is arranged above the cuff, and the orifice sucks sputum above the cuff to prevent the retentate above the respiratory tract from causing infection.

In the existing tracheal intubation production technology, the trachea and cuff are manufactured in different procedures, and then the trachea and cuff are assembled in an assembly line. The cuff is a plastic product in the shape of a sleeve. The cuff is sleeved on the outer wall of the trachea, and the two ends of the cuff, which are contacted with the trachea, are fixed ends. The fixed end tension is bigger, can extrude tracheal outer wall and prevent the cover bag removal. An inflation part is arranged between the fixed ends of the cuff and can be inflated when inflated.

In order to prevent the fixed end of the cuff from shielding the orifice of the sputum suction tube, the orifice can only be arranged above the fixed end of the cuff, so that a cleaning dead angle is reserved between the orifice and the inflatable part, and sputum is accumulated between the inflated inflatable part and the fixed end.

Therefore, in order to eliminate the clearance dead angle that exists between mouth of pipe and the portion of aerifing, this application provides an anti-hydrops trachea cannula.
