Whether appropriate to the processing of difficult airway, be the key of Anesthetic safety and quality. In " difficult airway managerial expert suggestion " (hereinafter referred to as " expert opinion ") that expert group of Chinese Medical Association anesthesia branch proposes, point out: more than 50% serious anesthesia related complication causes by airway management is improper, and one of the most urgent and serious problem that wherein face shield dysventilation runs in clinical anesthesia work especially. If this thing happens, just cannot implement effective artificial ventilation, patient at short notice just can be because anoxic causes cardiac arrest, and brain damage is even dead. And in " expert opinion ", recommended four kinds of instruments that solve urgent air flue (difficult face shield ventilation has difficult tracheal intubation concurrently), but in use all there is certain weak point in these instruments, is now described below:
1, face shield positive airway pressure: insert double face shield pressure-vent after oropharynx or nasopharyngeal air duct, and in daily work, as while running into serious face shield dysventilation, this method ventilatory effect is not very good, possible reason is: the position after oropharynx or nasopharyngeal air duct are put into is relatively fixing, and buckling after face shield and can not carry out active accommodation to their position, limited to the releasing effect of glottis Upper respiratory tract obstruction.
2, laryngeal mask: be air flue instrument on current widely accepted topmost glottis. It is easy and simple to handle, does not need laryngoscope auxiliary, and well-trained doctor can insert laryngeal mask and set up ventilation in several seconds, but as the shortcoming of the laryngeal mask of pointing out in " expert opinion " was: patient's mouth opening must be greater than 3cm, and throat structure is normal.
3, oesophagus-tracheae catheter for combining: the clinical use of this catheter for combining is little, the anesthesia personnel of basic unit did not even meet the material object of this catheter for combining mostly. Once the air flue of meeting difficulty, can miss an opportunity because of a delay because of the lack of skill using, cause patient's rescue failure.
4, pipe and air-breather are put in thyrocricocentesis: this method is one to have wound method, easily damages air flue, is only interim measure. It can only be used for oxygen supply or connect high-frequency ventilation machine, is easy to cause carbon dioxide retention, needs the follow-up method of Rapid Establishment, to solve ventilation.
5, the visual ventilation laryngoscope (patent No.: the visual ventilation problem while 201220117131.4) just having solved difficult airway, and can not carry out trachea cannula in visual ventilation that in addition State Intellectual Property Office of the People's Republic of China authorizes utility model patent.
The content of invention:
The object of invention: can only visual intubate in difficult treatment air flue process in order to overcome existing visible laryngoscope, and without ventilatory function, and visual, ventilation, these three processes of intubate can not be carried out to this deficiency simultaneously. The invention provides a kind of visual vented cannula laryngoscope, this laryngoscope can be in the time meeting difficulty air flue, utilize the clear and definite region of obstruction of visual techniques, remove airway obstruction, ventilation is carried out smoothly, simultaneously again can intranasal visual trachea cannula, reach visual, ventilation, these three processes of intubate are carried out this purpose, the retention of the scarce oxygen and carbon dioxide while having avoided difficult airway to process simultaneously.
In order to reach as above object, the present invention takes following technical scheme: comprise visual ventilation handle, visual ventilation handle contains ventilation tube chamber and visual structure, and ventilation tube chamber, with visual structure is adjacent, walk abreast, becomes entirety. Visual ventilation handle front end can be inserted in disposable laryngoscope blade, has unaerated cuff and sleeve bag gas-filling mouth on disposable laryngoscope blade.
The further technical scheme of the present invention is: described visual ventilation handle upper end is connected in display screen.
The further technical scheme of the present invention is: described ventilation tube chamber upper end has upper vent, lower end to have lower blow vent.
The further technical scheme of the present invention is: described upper vent can be connected with narcotic screwed pipe.
The further technical scheme of the present invention is: the unaerated cuff on described disposable laryngoscope blade can become the rear cuff of inflation by the inflation of sleeve bag gas-filling mouth.
Adopt as above the present invention of technical scheme, there is following beneficial effect: the invention provides a kind of visual vented cannula laryngoscope, this laryngoscope can be in the time meeting difficulty air flue, utilize the clear and definite region of obstruction of visual techniques, remove airway obstruction, ventilation is carried out smoothly, simultaneously again can intranasal visual trachea cannula, reach visual, ventilation, these three processes of intubate are carried out this purpose simultaneously, the retention of the scarce oxygen and carbon dioxide while having avoided difficult airway to process. And just existing visible laryngoscope is transformed a little, increased a ventilation tube chamber and on disposable laryngoscope blade, increase an inflatable cuff, simple in structure, easy to operate.
