Trachea cannula with ultrathin sacculus

Abstract

The invention discloses a trachea cannula with an ultrathin sacculus. The trachea cannula comprises a catheter, the sacculus and an inflation tube, the sacculus is arranged at one end of the catheter,one end of the inflation tube is communicated with the sacculus while the other end of the same is connected with outside inflation equipment, wall thickness of a sacculus inflation portion is smaller than 0.1mm, and wall thickness of a sacculus fixing portion is smaller than 0.3mm. By adopting the trachea cannula, irritation of the sacculus to a tracheal wall during inserting of the catheter isreduced; a hot pressing process is adopted to bond the sacculus, so that using of organic matters like cyclohexanone for bonding is avoided, and biocompatibility of the trachea cannula is improved.

Description

Technical field [0001] The invention relates to a tracheal intubation, in particular to a tracheal intubation with an ultra-thin balloon. Background technique [0002] The existing tracheal intubation tube generally includes a catheter for inserting into the trachea of ​​a patient. The head of the catheter is equipped with a balloon for closing the gap between the catheter and the wall of the patient’s trachea. An inflatable tube is provided in the wall of the catheter. The balloon is connected, and the other end of the inflation tube is led out from the tail of the catheter for connection with external inflation equipment. When the catheter is not inserted into the patient’s trachea, the balloon is in a deflated state. After the catheter is inserted into the patient’s trachea, the balloon is inflated through the inflation tube. It is attached to the patient's tracheal wall to prevent air leakage and prevent aspiration after reflux of oropharyngeal secretions and gastric contents...

AI Technical Summary

Problems solved by technology

Traditional tracheal intubation, the balloon is bonded to the catheter by glue, the wall thickness of the inflatable part of the balloon is greater than or equal to 0.1mm, the wall thickness of the fixed part of the balloon is greater than or equal to 0.3mm, and there is an obvious step at the connection between the fixed part of the balloon and the catheter , and because the traditional balloon is made of PVC material with low elasticity and toughness, the balloon must reach the inflated shape and size during molding. Wrinkles and bulges appear on the lower part of the body, causing certain damage or discomfort to the patient's trachea
