This utility model is set up one section soft seal wire at existing seal wire tail end, its role is to: when guiding tube arrives near the thyrocricoid puncture point along seal wire, needn't resemble and extract seal wire out the method previously, and guiding tube and seal wire together can be pushed into air flue, make operation more easy.Soft seal wire can not damage the respiratory mucosa tissue, and is drawn out of from guiding tube easily after operation is finished.
The soft seal wire of the long 5～7cm of tail end can play containment guides effect preferably.
The soft seal wire of tail end and the joint of superhard seal wire are designed to bending, more help it is dragged in the introducing air flue, and can not damage the respiratory mucosa tissue, when bringing air flue into because of the guiding tube propelling is passive, the traction of forniciform soft seal wire has also guaranteed the propelling of guiding tube along air flue dead ahead inwall, thereby avoid it when extracting seal wire, to be shifted or resilience skids off may going of air flue, and increase the success rate of intubate.
On soft seal wire scale mark being set, is when guiding tube and seal wire tail end to be sent into air flue in order to identify.
Scale mark is set on stiff guide wire, is in order to identify the insertion depth of guiding tube.
This utility model compared with prior art has the following advantages:
(1) operation is easier.Tradition seal wire guiding method need be strained seal wire when operation, and firmly guiding tube and endotracheal tube is pushed up to glottis and air flue front end, and when extracting seal wire and guiding tube out, taking advantage of a situation pushes endotracheal tube in the air flue.And use this seal wire seal wire and guiding tube can be pushed in the lump into air flue, and then endotracheal tube is imported in the air flue.
(2) reduce tissue injury.Need not when extracting seal wire firmly guiding tube and endotracheal tube top to glottis and air flue front end, thereby avoid the damage of local organization structure.
(3) improve success rate.Guiding tube is in progradation, curved soft header structure has played good containment guides effect, guaranteed the propelling of guiding tube, thereby avoided it when extracting seal wire, to be shifted or resilience skids off the probability of air flue, and increased the success rate of intubate along air flue dead ahead inwall.
