Background

The trachea intubation operation is a technology for placing a special trachea intubation tube into a trachea through a glottis, and the technology can provide optimal conditions for smooth air passage, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like.

At present nasal trachea cannula operation often adopts the director to guide trachea cannula to put into the trachea to this success rate that improves the intubate also avoids using intubate pincers to guide trachea cannula among the intubate process, thereby alleviates the patient in the painful of intubate in-process.

However, the introducer in the prior art needs to be inserted into the trachea by probing the introducer with a hard tube core, or the endotracheal tube needs to be inserted into the patient together with the introducer for intubation exploration, and the endotracheal tube with a hard tube core or a relatively thick tube diameter inevitably damages the patient during the intubation exploration.

For example, patent No. CN200620151492.5 discloses an endotracheal intubation guide device, which has an improved intubation success rate, but needs to be probed and inserted into the trachea with a tube core with certain firmness exposing a guide tube, the tube core is withdrawn after being inserted into the trachea, the tube core is left in the patient, and the tube core with certain firmness inevitably causes injury in the patient.

For example, in the patent with application number CN200420032811.1, a combined endotracheal tube is provided, which improves the success rate of intubation, but the endotracheal tube is inserted into the patient along with the guiding tube and the tube core during intubation to perform intubation exploration, and the endotracheal tube has a relatively thick tube diameter, which may damage the patient during intubation exploration.
