It addition, for the different phase of same patient treatment, traditional T pipe then need different change and
Adjusting, this patient also brings misery and inconvenience.
2) material of existing T pipe is silica gel, and the T pipe of silica gel material is the most consistent with tracheal diameter,
Continue tracheas suppressed, may result in tunica mucosa tracheae ischemia, and then cause mucosa cicatrix, and
The T pipe range time directly contacts endotracheal mucosal, may stimulate granulation growth.Postoperative taking-up T manages
After, inner surface of trachea cicatricial contracture, cavum laryngis restenosis can be caused, and then cause difficulty in decannulation.Separately
Outward, traditional hard gel is persistently oppressed and is easily formed new cicatrix, and after tube drawing, restenosis sends out
Raw rate is the highest.
