Embodiment

[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 ...

Abstract

The invention relates to a tracheal catheter for creating an air passage for artificial ventilation for a patient in anesthesiology or emergency medicine, and in particular relates to a tracheal catheter which is characterized by being provided with a corrugated air sac. When the tracheal catheter is expanded, the air sac has a corrugated structure, and the outer side surface of the air sac is in a shape of water wave, therefore, the original functions of the air sac are maintained, namely the air sac is used for blocking a space between the tracheal catheter and the inner wall of a trachea so as to prevent nasopharyngeal secretions from flowing into the trachea and prevent air leakage during a positive-pressure ventilation period, and meanwhile, a contact surface between the air sac and a tracheal mucous membrane can be minimized, and the possibility of complicating diseases, such as ischemic injury and sore throat, caused by the tracheal catheter can be remarkably reduced.

Description

technical field [0001] The invention relates to a tracheal tube used for establishing an airway and artificial ventilation for a patient in anesthesiology or emergency medicine, in particular to a tracheal tube with a corrugated air bag. Background technique [0002] Generally speaking, an endotracheal tube is used as an air channel to directly transmit oxygen and anesthetics to patients. One side of a cylindrical tube with a predetermined length forms an open end portion inserted into the trachea, and the opposite side forms a connection. on the open base end of the gas supply. [0003] Typically, an endotracheal tube is one that forms a seal with the inner wall of the trachea, with a balloon designed to inflate on the outside of the cylindrical tube. The air bag functions to block the trachea and prevent foreign matter from being inhaled into the trachea and lungs. In particular, it prevents food, foreign organisms or contents of the digestive system from entering the lu...
