Operation exception.
Preferably, image acquisition device 3 uses miniature webcam, image receiver and 6 wired or wireless connection of display, shows
It is PC machine or mobile phone to show device 6.
When in use, 10 power supply opening of light source will be with image acquisition device 3 for visual trachea cannula provided by the invention（It is miniature
Camera）Connected picture fibre 4 is connected with the picture receiver 5 being placed in outside looped pipeline 2, and causes picture receiver 5 and display 6
（Display 6 is has screen electronic product, such as mobile phone, PC machine）Pass through bluetooth connection, you can start PC machine operation, during insertion, pass through
Miniature webcam shoots oral cavity and tracheae, so as to adjust the curvature of visual trachea cannula according to the image of camera shooting；When visual
After trachea cannula insertion tracheae, wire drawing 7 is broken so as to extract wire drawing main body 71 out looped pipeline 2, and miniature webcam is pulled out into looped pipeline
2, it puts and stays the cannula body 1 in patient airway.
During intubation, since the wall thickness of the first selection area is at least above the axis along cannula body 1 and with inserting
The wall thickness of the second symmetrical selection area of first selection area of pipe main body 1, and in the looped pipeline 2 on the first selection area
It is provided with as fibre 4, picture receiver 5 and wire drawing 7, it is selected more than second so as to cause the quality of side where the first selection area
So that visual trachea cannula is in the state laid particular stress on, cannula body 1 is adjusted when utilizing wire drawing 7 for the quality of side where region
Curvature when, the second selection area of cannula body 1 and the junction of wire drawing 7 are under the action of pulling force to cannula body 1
First selection area is close, i.e. the second selection area and the junction of wire drawing 7 are shunk inwardly, due to being subject to the second selection area
With affecting for the junction of wire drawing 7, and because visual trachea cannula lay particular stress on situation, the top ends of visual trachea cannula can be easily
Form bending situation.Therefore, visual trachea cannula provided by the invention can conveniently, swimmingly, rapidly adjust curvature, keep away
Exempt from cannula body distortion and can not quickly realize that curvature is adjusted, and then reduce the pain of sufferer intubation.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use the present invention.
A variety of modifications of these embodiments will be apparent for those skilled in the art, it is as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and the principles and novel features disclosed herein phase one
The most wide scope caused.
