Description
Technical field
The invention belongs to technical field of medical instruments, and in particular to a kind of visual optical wand of drug injection trachea cannula.
Background technology
At present, existing trachea cannula blindmate method is to use the guide device auxiliary intubation with optics indicator function, should
The front end of guide device can emit beam, and light can penetrate the tissue between the tracheae of patient and throat portion, and doctor passes through observation
The hot spot position of patient's skin of anterior portion of neck judges the position arrived at of intubation.Although it this method solve conventional tracheal intubation
Method easily causes the problem of site tissues such as human oral cavity, throat easily damage, but the current device for being applicable this method, i.e.,
Problems with is also there are in guide device：
1st, traditional optical wand is a metal cecum, and in the clinical anesthesia operation of special circumstances, often leading core because of optical wand does not have
Administration channel, medicine, complex operation, drug injection effect not in place need to be injected by common laryngoscope or thyrocricocentesis before intubation
Fruit is not good enough, causes that smooth air flue can not be entered during trachea cannula, causes the irritable enhancing of patient airway, and air flue soft tissue injury is tight
Weight；
2nd, by the guide device auxiliary intubation of optics indicator function, the front end of the guide device can be sent traditional optical wand
Light, light can penetrate the tissue between the tracheae of patient and throat portion, and doctor is by observing the hot spot of patient's skin of anterior portion of neck
Position judges the position arrived at of intubation, but can not intuitively see the situation inside trunnion, can not be to need to carry out
The region of accurate injection medicine provides help；
3rd, existing product does not put forth effort handle, and product requires accurate, quick, reduced to greatest extent to air flue in use
Loss, thus it is easy to use, smoothly, handy power be product that clinician needs most；
4th, battery is non-exchange in existing product, charges, and is integrally scrapped after out of power, causes to waste, also not environmentally, increases hospital
And patient burden；
5th, existing product feux rouges only has in front end, and position is bad in such as intubation guiding or ob esity's reason causes feux rouges
Penetrate unclear, trachea cannula will be influenceed.
In order to solve the above technical problems, medical worker has also carried out substantial amounts of research, for example, Publication No.
CN202892594U Chinese patent discloses " a kind of optical wand for guiding trachea cannula of sprayable injection medicine ", the optical wand for guiding
Medicine need not be injected by common laryngoscope or thyrocricocentesis, only need to spray injection medicine according to situation when inserting optical wand intubation,
It is small with improvement air flue state simple in construction, easy to operate, easy, resistance, when reducing the damage of air flue soft tissue, shortening intubation
Between, reduce air flue it is irritable, improve the success rate and security of trachea cannula.But due to that intuitively can not see in trunnion
The situation in portion, accurate injection medicine can not be carried out, and the method by spraying medicine carries out the ineffective of local treatment, far
The effect treated far away from accurate injection medicine.The Chinese patent that and for example number of patent application is CN200910054430.0 is public
" a kind of visual trachea cannula guiding device " is opened, the guide device application camera gathers the image of air flue, with electron luminescence
Diode transmits video, the air flue of intubation can be watched on the display screen of signal output part, convenient as light source with circuit soft board
Tracheal catheter enters tracheae.But visual trachea cannula guiding device effect is single, only with guiding function, can not carry out
Accurate injection operates.
The content of the invention
For overcome the deficiencies in the prior art, the present invention devises a kind of visual optical wand of drug injection trachea cannula, this medicine
Inject trachea cannula visual optical wand not only can by the screen information inside the thecamera head trunnion of optical wand front end,
And shown by display screen, and accurate injection can be carried out by the injection device installed in optical wand front end.
To realize above-mentioned technical proposal, the invention provides a kind of visual optical wand of drug injection trachea cannula, including：Injection
