Abstract

The invention relates to a method for guidance tracheal intubation of difficult airway, comprising the following steps: inserting a video laryngoscope lens provided with a tracheal intubation guide channel into oral cavity and exposing glottis; introducing a tracheal guild tube core in the glottis through the tracheal intubation guild channel; separating tracheal guide tube core from the trachealintubation guide channel added from the video laryngoscope lens; sheathing the tracheal guide tube in the tracheal guide tube core and inserting the tracheal guide tube into the trachea of human bodyvia the glottis through the tracheal guide tube core under the monitoring of the video laryngoscope; extracting the tracheal guide tube core from the tracheal guide tube under the monitoring of the video laryngoscope; aborting the video laryngoscope lens with the tracheal intubation guide channel from laryngeal. The invention has the advantages of not only increasing the exposition condition of the intubation, but also avoiding damage of organs in guttural part, solving the difficult tracheal intubation under all laryngoscope lenses.

Description

A kind of method for guidance tracheal intubation of difficult airway

Technical field

The insertion method of person's windpipe conduit when the present invention relates to a kind of clinical anesthesia and rescue, be particularly related to a kind of person's windpipe insertion method that is used for the band tracheal intubation guiding device of difficult airway intubate, the structure of the tracheal intubation guiding groove of particular design is applicable to the difficult intubation occasion of tracheal intubation under all laryngoscopes.

Background technology

Need carry out the insertion of person's windpipe conduit when clinical urgent rescue or general anesthesia, but the people was in and suffocated or the apnea state this moment, though electric video laryngoscope has improved the intubate exposure condition, still have and put pipe difficulty or the high phenomenon of bottleneck throat organ injury incidence rate; Special in the higher patient of larynx, the probability of putting pipe difficulty or bottleneck throat organ injury is higher.

The applicant is in the utility model 200920067327.5 of first to file, denomination of invention is " video laryngoscope that is used for the band tracheal intubation guiding groove of difficult intubation ", design a tracheal intubation guiding groove and trachea guiding tube core, this device is particularly suitable for the difficult intubation occasion.

Summary of the invention

Technical problem to be solved by this invention has provided a kind of method for guidance tracheal intubation of difficult airway, is not a kind of Therapeutic Method.

In order to solve above technical problem, the invention provides a kind of method for guidance tracheal intubation of difficult airway, this method is based on a kind of video laryngoscope that is used for the band tracheal intubation guiding groove of difficult intubation, the laryngoscope blade that comprises band handle and tracheal intubation guiding groove, this handle is provided with tracheal intubation guiding groove camber and that have notch, the trachea guiding tube core that can intert in the tracheal intubation guiding groove also can be deviate from from notch, and trachea guiding tube core rear end is guided an endotracheal tube and inserted person's windpipe; The step of this method is as follows:

Step 1: the video laryngoscope sheet that the tracheal intubation guiding groove will be housed inserts the oral cavity and exposes glottis;

Step 2: under video laryngoscope monitors, a trachea guiding tube core is imported glottis by this tracheal intubation guiding groove;

Step 3: guide tube core to pass through tracheal intubation guiding groove notch and guiding groove disengaging trachea;

Step 4: endotracheal tube is inserted in trachea guiding tube core, and under video laryngoscope monitors, endotracheal tube is inserted person's windpipe through glottis by trachea guiding tube core;

Step 5: under video laryngoscope monitors, guide tube core in endotracheal tube, to extract out trachea;

Step 6: the video laryngoscope sheet that will have the tracheal intubation guiding groove withdraws from from throat.

Described tracheal intubation guiding groove and video laryngoscope sheet are fixed as one or flexibly connect.

Described tracheal intubation guiding groove is the pipe of trough of belt mouth, or has clip, the hook of bayonet socket, and the pipe of trough of belt mouth can hold trachea guiding tube core, and the clip, the hook that have bayonet socket can block trachea guiding tube core and enter person's windpipe, and can separate with it.

Superior effect of the present invention is:

1) trachea can be guided tube core to import the glottis position that any electric video laryngoscope can expose, reboot endotracheal tube and finish intubate operation under the difficult occasion;

2) under video monitor, import trachea guiding tube core earlier by the electric video laryngoscope sheet that has the tracheal intubation guiding groove, import the intubation procedure of endotracheal tube again by trachea guiding tube core, solved general video laryngoscope and can only expose glottis in some difficult intubation occasion, and the situation that endotracheal tube can not insert, thereby can carry out the endotracheal tube intubate in the hell and high water occasion;

3) use the video laryngoscope of being with the tracheal intubation guiding groove, can improve the intubate exposure condition and can avoid the bottleneck throat organ injury again, solved the difficult tracheal intubation under all laryngopharyngeal mirrors.

The specific embodiment

Below the invention will be further described.

The band handle of sterilizing and the laryngoscope blade 1 of tracheal intubation guiding groove are engaged with the socket of handle cutting ferrule, click operating switch, liquid crystal display and illumination LED lamp are lighted.

Video laryngoscope sheet 1 is inserted the patient oral cavity, image sensor photographic head and the intravital video signal processing circuit of laryngoscope shell are transformed into video signal with the endotracheal image of patient and are shown on the display screen of liquid crystal display, the operator exposes patient's glottis by the liquid crystal display that observation is installed on the handle, earlier trachea is guided tube core 2 to insert patient's glottis 3 by the tracheal intubation guiding groove, then trachea is guided tube core 2 to deviate from from the tracheal intubation guiding groove by the breach on the tracheal intubation guiding trough rim, endotracheal tube 4 is inserted in trachea guiding tube core 2, along trachea guiding tube core 2 endotracheal tube 4 is inserted patient's glottis 3, again trachea is guided tube core 2 to extract out, withdraw from video laryngoscope sheet 1 at last, finish whole tracheal intubation intubate process.
