Abstract
This utility model relates to technical field of medical instruments, particularly relates to a kind of guidance tracheal intubation that drives in the wrong direction; Comprise endotracheal tube (1), run through being provided with transition guide wire (2) in endotracheal tube (1), run through being provided with guide wire (3) in transition guide wire (2), the front end of guide wire (3) is provided with the first arc elbow (4); The head end of the guide wire of the retrograde guidance tracheal intubation that this utility model provides bends, and is easy to enter oral cavity, when pushing endotracheal tube to pars oralis pharyngis, reduces the chance producing card pipe between endotracheal tube and epiglottis.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of guidance tracheal intubation that drives in the wrong direction.
Background technology
At present, be applied to clinical retrograde guidance tracheal intubation in use, guide wire from oral cavity out after, endotracheal tube send into tracheal strips time can be stuck on epiglottis, the patient of cervical region Huge mass cannot implement; After thyrocricoid puncture, guide wire is easy to enter nasal cavity, needs to use artificial clamp, involves oral cavity from pharyngeal, increases the operating time; And guide wire produces Soft tissue cutting damage when larynx is inserted.
Summary of the invention
This utility model for overcoming the deficiencies in the prior art, and provides a kind of guidance tracheal intubation that drives in the wrong direction.
The one that this utility model provides is driven in the wrong direction guidance tracheal intubation, and comprise endotracheal tube, run through and be provided with transition guide wire in endotracheal tube, run through being provided with guide wire in transition guide wire, the front end of guide wire is provided with the first arc elbow.
The rear end of guide wire is provided with the second arc elbow, and the first arc elbow and the second arc elbow are positioned at the homonymy of guide wire.
The front end of endotracheal tube is circular sharp-crested, and the side of circular sharp-crested is provided with and is no less than a side opening.
Transition guide wire length 10-12cm longer than endotracheal tube.
The long 1.0cm of tip portion of transition guide wire front end.
Beneficial effect:
1, the head end of the guide wire of retrograde guidance tracheal intubation that this utility model provides bends, and is easy to enter oral cavity, when pushing endotracheal tube to pars oralis pharyngis, reduces the chance producing card pipe between endotracheal tube and epiglottis.
Whether 2, the front end of guide wire, the first elbow of rear end, the second elbow are positioned at the homonymy of guide wire, be easy to identify direction, can observe out guide wire more intuitively and rotate in oral cavity.
3, the front end of endotracheal tube is circular sharp-crested, and band side opening, reduces aeration resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of retrograde guidance tracheal intubation embodiment 1 of this utility model;
Fig. 2 is the structural representation of a kind of retrograde guidance tracheal intubation embodiment 2 of this utility model;
Fig. 3 is the structural representation of a kind of retrograde guidance tracheal intubation embodiment 3 of this utility model.
Detailed description of the invention
Embodiment 1: as shown in Figure 1, a kind of guidance tracheal intubation that drives in the wrong direction, comprise endotracheal tube 1, run through being provided with transition guide wire 2 in endotracheal tube 1, run through being provided with guide wire 3 in transition guide wire 2, the front end of guide wire 3 is provided with the first arc elbow 4.
The head end of the guide wire of the retrograde guidance tracheal intubation that this utility model provides bends, and is easy to enter oral cavity, when pushing endotracheal tube 1 to pars oralis pharyngis, reduces the chance producing card pipe between endotracheal tube 1 and epiglottis.
Embodiment 2: as shown in Figure 2, a kind of guidance tracheal intubation that drives in the wrong direction, comprise endotracheal tube 1, run through being provided with transition guide wire 2 in endotracheal tube 1, run through being provided with guide wire 3 in transition guide wire 2, the front end of guide wire 3 is provided with the first arc elbow 4.
The head end of the guide wire of the retrograde guidance tracheal intubation that this utility model provides bends, and is easy to enter oral cavity, when pushing endotracheal tube 1 to pars oralis pharyngis, reduces the chance producing card pipe between endotracheal tube 1 and epiglottis.
The rear end of guide wire 3 is provided with the homonymy that the second arc elbow 5, first arc elbow 4 and the second arc elbow 5 are positioned at guide wire 3.
The front end of guide wire 3, the first elbow 4, second elbow 5 of rear end are positioned at the homonymy of guide wire 3, are easy to identify direction.
Embodiment 3: as shown in Figure 3, a kind of guidance tracheal intubation that drives in the wrong direction, comprise endotracheal tube 1, run through being provided with transition guide wire 2 in endotracheal tube 1, run through being provided with guide wire 3 in transition guide wire 2, the front end of guide wire 3 is provided with the first arc elbow 4.
The head end of the guide wire of the retrograde guidance tracheal intubation that this utility model provides bends, and is easy to enter oral cavity, when pushing endotracheal tube 1 to pars oralis pharyngis, reduces the chance producing card pipe between endotracheal tube 1 and epiglottis.
The rear end of guide wire 3 is provided with the homonymy that the second arc elbow 5, first arc elbow 4 and the second arc elbow 5 are positioned at guide wire 3.
The front end of guide wire 3, the first elbow 4, second elbow 5 of rear end are positioned at the homonymy of guide wire 3, are easy to identify direction.
The front end of endotracheal tube 1 is circular sharp-crested 6, and the side of circular sharp-crested 6 is provided with and is no less than a side opening 7.Sharp-crested is little, then endotracheal tube 1 is by drag reduction during epiglottis, but aeration resistance increases.Sharp-crested is large, then endotracheal tube 1 is increased by resistance during epiglottis.This utility model adopts circular sharp-crested 6, and band side opening 7, reduces aeration resistance.
Transition guide wire 2 length 10-12cm longer than endotracheal tube 1, overall length 40cm, long, be too shortly inconvenient to operate; And comparatively hard, there is certain elasticity, endotracheal tube 1 can be supported, conveniently send pipe.Guide wire 3 is inserted via the trocar, to reduce the cutting damage that tractive guide wire 3 produces.
