[0048] In 2009, the Korean Society of Anesthesiology (Korean J Anesthesiol, 2009, 56(5): 513-518) used the research and experimental method for the evaluation of tracheal tubes to regard the disposable syringe tube as the trachea of humans and animals, and the trachea The contact surfaces were compared after the catheter was attached to the syringe tubing to inflate the balloon.
[0049] The endotracheal catheter of the present invention wraps silk threads at two parts of the conventional air bag so that the expansion cannot exceed a certain limit and at the same time a wave crest and three wave troughs are formed.
[0050] In the corrugated airbag part of the present invention, if calculated according to the transverse section length of the contact surface, the contact surface is about 1mm, and the transverse section length of the three contact surfaces is 3mm in total. On the contrary, the transverse cross-sectional length of the contact surface of the conventional airbag ...
