Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, tracheal intubation includes with visual tube core: handle 1, circuit board 2, steel wire 3, tube core body 4, torque spring 5, controls bar 6, photographic head 8.
Handle 1, grips for user.
Tube core body 4, it is possible to bending, adopts the metal tube of shaping to make, in other embodiments in the present embodiment, it would however also be possible to employ the macromolecular material with flexibility is made；Handle 1 is installed in the rear end of tube core body 4.
Photographic head 8, as in figure 2 it is shown, photographic head 8 is arranged on movable head 17, movable head 17 is rotatably connected on the front end of tube core body 4.
Circuit board 2, is arranged in handle 1, is connected with photographic head 8 by holding wire 7, controls and process photographic head 8 to shoot image.Circuit board 2 has wireless signal transmitter, the picture signal C that photographic head 8 photographs is launched.
Control bar 6, be rotatably installed in the end of handle 1；
Fig. 2 is the partial enlarged drawing of a-quadrant in Fig. 1, as in figure 2 it is shown, steel wire 3, one end is connected with controlling bar 6, and after tube core body 4, the other end is connected with photographic head 8.When to the direction rotation control rod 6 of arrow B in Fig. 1, control bar 6 and pull steel wire 3, steel wire 3 to drive photographic head 8 to tilt.
Torque spring 5, is arranged on the junction controlling bar 6 with handle 1, applies elastic force to controlling bar 6, and when to the direction rotation control rod 6 of arrow B in Fig. 1, torque spring 5 is tightened, and when loosening control bar 6, control bar 6 is popped into position and puts by torque spring 5.
Spacing ring 16, is arranged on inside the front end of tube core body 4, and steel wire is connected through rear with photographic head 8 in spacing ring 16.
With the combination of visual tube core and display 9, tracheal intubation in Fig. 1 is called that tracheal intubation unit, display 9 have battery and a signal receiving device by the present invention, receive picture signal C that photographic head 8 collects and show that image is out.
The tracheal intubation combination of visual tube core, display 9 and oropharyngeal airway is called endotracheal intubation system by the present invention.
As shown in Figure 3 and Figure 4, oropharyngeal airway, there is disk 10, airway body 11, breach 12, wedge shape cecum 13.
Airway body 11, is shaped as the arc that the radian of the oral cavity with human body and throat matches.
Disk 10 is annular, is arranged on one end of airway body 11, and middle opening is consistent with the opening of airway body 11.
Wedge shape cecum 13, is arranged on the other end of airway body 11,
Breach 12, is opened on the other end of airway body 11, corresponding with wedge shape cecum 13.The inclined-plane of wedge shape cecum 13 is towards breach 12.
Having thin pipe 18 in the sidewall of oropharyngeal airway, the first opening 14 is positioned on disk, and the second opening 15 is positioned on wedge shape cecum 13, towards breach 12.Thin pipe 18 can be passed through spray local anaesthetics to epiglottis glottis or attract pharyngeal secretions or blood.
During use, as it is shown in figure 5, be first placed in by oropharyngeal airway in patient oral cavity, the breach 12 of oropharyngeal airway end is positioned at patient epiglottis 20 place.The thin pipe 18 can passed through on disk sprays local anaesthetics to epiglottis glottis, owing to the second opening 15 is towards epiglottis 20, therefore improves the accuracy that anaesthetic sprays.Can also attract out by pharyngeal secretions or blood by thin pipe 18.Tube core body 4 is bent to and oropharyngeal airway identical radian measure, endotracheal tube is enclosed within tube core body 4, inserted by oropharyngeal airway, when the head of tube core body 4 is positioned at after below epiglottis and presses control bar 6 makes photographic head 8 tilt, at this moment can pass through display 9 and see glottis, under photographic head monitors, endotracheal tube be sent into glottis.For the prominent tracheal intubation structure of visual tube core in figure, omit endotracheal tube.
In other embodiments, it is also possible to do not use oropharyngeal airway, it is used alone the visual tube core of tracheal intubation and display carries out tracheal intubation.
