Specific embodiment
The specific embodiment of the present invention to be described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the oropharyngeal airway of the present embodiment.
Fig. 2 is the side view of the oropharyngeal airway of the present embodiment.
Fig. 3 is the structural representation of the Section A-A in Fig. 1.
As shown in FIG. 1 to 3, oropharyngeal airway 100 is included by top-surface camber 1, lower surface camber 2 and the company connecting two curved surfaces
The oropharyngeal airway body of junction 3 composition, positioned at the video portion 6 on joint face 3 top, is power supply 7 and the position of video portion 6 power supply
In the external, display part for showing video portion 6 image.
In oropharyngeal airway body, top-surface camber 1 includes being in the first top-surface camber 11 and second of seesaw-type along joint face 3
Top-surface camber 12, the first top-surface camber 11 and its corresponding lower surface camber 21 constitute first passage 4, the second top-surface camber 12 and its corresponding to
Lower surface camber 22 constitute second channel 5, first passage 4 or second channel 5 are both used for improving ventilation and are also used for guiding endotracheal tube
Insertion.Joint face 3 carries multiple apertures 31, for when side channel blockage, gas can enter other one through small holes 31
Wing passage, meets ventilation requirement, and the section of first passage 4 and second channel 5 is C font in order in catheterization procedure,
Prevent endotracheal tube from departing from passage.
The profile of oropharyngeal airway 100 is similar with oropharyngeal airway of the prior art, also with oral cavity and pharyngeal shape
Shape matches, and is also classified into the edge of a wing 10, bite-block bite 20 and pharynx bending section 30, the knee of top-surface camber 1 is little lateral bending, with tongue
Back of the body radian coincide, and the knee of lower surface camber 2 is big lateral bending, is affixed with soft, hard palate and pharynx rear wall.
In order to prevent during whole operation, the unartificial active sexual activity of top-surface camber 1, setting at the edge of a wing 10
Frame 8, support 8 includes being respectively arranged at the first support 81 at first passage 4 and second channel 5 edge of a wing and second support 82.The
One support 81 is identical with second support 82 structure, and all in hook-shaped, support one end and lower surface camber rotate and connect, and another end hook is in upper
On the edge of a wing of curved surface, it is used for fixing the first top-surface camber and the second top-surface camber.
Fig. 4 is the structural representation in the video portion in the present embodiment.
As shown in Figure 1 and Figure 4, video portion 6 is annular in shape, and middle is image unit 61, is a plurality of around image unit 61
Luminous body 62.Power supply 7 be button cell, positioned at lower surface camber 2 away from video portion 6 one end, power supply 7 pass through wire and video portion 6
Connection, is image unit 61 and luminous body 62 is powered.Wire is very thin, by the gap that is arranged in joint face 3 connect battery and
Video portion 6.
It is support 8 to the control parts of 6 on-off actions in video portion, have and only first support 81 and second support 82
In the case of all departing from top-surface camber, image unit 61 and luminous body 62 are just de-energized.
In the present embodiment, image unit is micro radio photographic head, and luminous body is LED bulb, and display part is micro- for receiving
The display screen of the wireless signal that type wireless camera is sent.Display location, in external, is powered for it using other power supply, leads to
Cross internal wireless signal receiver and receive the wireless signal with regard to glottis structure that micro radio photographic head sends.
In the present embodiment, the connected mode of the first top-surface camber and the second top-surface camber is similar to hinge.Upper end by joint face
Widen, upper end both sides slightly projection, and one and the connection of two lateral processes and joint face upper end shape identical axle are set, outer shaft sleeve has
Sleeve pipe, the first top-surface camber and the second top-surface camber are horizontally placed on the two ends of sleeve pipe respectively, and when pressing pressure side top-surface camber, sleeve pipe turns
Dynamic, drive opposite side top-surface camber to tilt.It is not necessary to the tilting degree of curved surface is very big in the present embodiment, if slight tilt so that
Passage is easily separated from endotracheal tube, and the therefore inner surface of sleeve pipe can be with the outer surface directly contact of axle, as long as keeping table
Face is smooth.
Under inserted the using method of the oropharyngeal airway in the present embodiment to be described along first passage 4 with endotracheal tube：First
First, oropharyngeal airway is inserted, now two side stands are in the state of closing, according to the image in display screen, judge that oropharynx leads to
Whether the position that air flue is placed is correct；Secondly, after mask ventilation terminates, when carrying out endotracheal tube intubation, open first support 81,
Now still in the state of closing, video portion 6 is in "on" position to second support 82, inserts endotracheal tube under the conditions of visual；?
Afterwards, after endotracheal tube insertion success, second support 82 is opened, power supply disconnects, press pressure the second top-surface camber 12 so that bent on first
Face 11 tilts, by oropharyngeal airway to the second top-surface camber 12 1 side shifting, will while endotracheal tube departs from from first passage 4
Oropharyngeal airway is withdrawn from from oral cavity.
The effect of embodiment and effect
Present embodiments provide a kind of oropharyngeal airway, including the oropharynx being made up of top-surface camber, lower surface camber and joint face
Airway body and the video portion for glottis structure observed in vitro, display part and power supply, in oropharyngeal airway body
Top-surface camber includes, with the first top-surface camber of seesaw-type connection and the second top-surface camber, pressing the one of curved surface of pressure, another lateral curvature
Face can tilt, and causes channel height adjustable so that the oropharyngeal airway of the present embodiment offer, while improving ventilation, also may be used
Using the guiding channel inserting as endotracheal tube, both solved the problems, such as that mask ventilation was difficult, and decreased again and exit common oropharynx
Airway, reuses the time spent by laryngoscope intubation, that is, the hypoxic exposure of patient when reducing the insertion of induction tracheal conduit, and
And reduce laryngoscope in operation, patient oral cavity is brought with the risk of damage.
In addition, the channel cross-section of the oropharyngeal airway of the present embodiment offer is in C font, effectively prevent guiding endotracheal tube
In insertion process, endotracheal tube departs from the phenomenon generation of passage, and meanwhile, support serves not only as the switch in video portion, also acts solid
Determine the effect of top-surface camber, it is to avoid top-surface camber unartificial active sexual activity, improve the insertion efficiency of endotracheal tube.
The invention is not restricted to the scope of specific embodiment, for those skilled in the art, as long as respectively
Kind of change described claim limit and the spirit and scope of the present invention that determine in, these changes be it will be apparent that
All utilize the innovation and creation of present inventive concept all in the row of protection.
