Among the figure, 1. eyeglass, 2. mirror handle, 3. draw-in groove, 4. main pipe entrance, 5. secondary duct entry, 6. waveform flange, 7 catch, 8. curved flanges, 9. banking stop, 10. guide pad, 11. view finders, 12. fins.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is elaborated.
This utility model provides a kind of visual laryngoscope, as shown in Figure 1, including front end is the eyeglass 1 of arc-shaped bend structure, eyeglass 1 inside is provided with the optical visible system, eyeglass 1 front end is provided with illuminator, eyeglass 1 rear end is connected with mirror handle 2, mirror handle 2 is provided with battery compartment and on and off switch, illuminator is connected with on and off switch with battery compartment on the mirror handle 2 by lead, eyeglass 1 side is provided with the draw-in groove 3 that advances for endotracheal tube, draw-in groove 3 extends to eyeglass 1 front end along eyeglass 1 side from eyeglass 1 rear end always, and draw-in groove 3 rear ends are provided with main pipe entrance 4, and the warp architecture place that draw-in groove 3 front ends are positioned at eyeglass 1 is provided with secondary duct entry 5.
During concrete enforcement, eyeglass 1 arc-shaped bend structure is near 90 °, and difficult exposure air flue glottis makes eyeglass 1 not need mouth, pharynx, larynx three deads in line just can see glottis easily.The optical visible system of eyeglass 1 inside adopts the combination of lens and prism that image is reached the view finder 11 of mirror handle 2 inside, thereby dissects and the endotracheal tube top around can seeing glottis, glottis.Connect video camera and image is passed to the convenient observation of display at view finder 11 alternatively.Eyeglass 1 front end illuminator adopts the light emitting diode of low temperature, and light emitting diode is connected with battery compartment and the on and off switch of setting in the back end mirror handle 2 by lead.The draw-in groove 3 of eyeglass 1 side is consistent the curvature of endotracheal tube and eyeglass 1 curvature, has avoided endotracheal tube because the moulding improper glottis that is difficult to insert.Draw-in groove 3 includes upper and lower two parallel clamping plate, and train wheel bridge and lower plate are extended out to the side by eyeglass 1 upper and lower surface respectively, thereby the train wheel bridge width can peel off endotracheal tube from the side less than the lower plate width.Train wheel bridge length is greater than lower plate length, and the part that grows forms the top of eyeglass 1, and eyeglass 1 top is provided with a fin 12, and this fin 12 is conducive to epiglottis is lifted the exposure glottis.The lateral edges of lower plate upwards bends up and can guarantee that endotracheal tube can not come off in progradation.The train wheel bridge of draw-in groove 3 rear ends and lower plate form main pipe entrance 4, upper and lower clamping plate stretch out and form waveform flange 6, wherein train wheel bridge has two minor undulations flanges 6, corresponding lower plate has a bigger waveform flange 6, big waveform flange 6 tops of bottom are provided with a catch 7, just in time below the trough between two the minor undulations flanges 6 in top, catch 7 is preferably trapezoidal catch 7, can guide endotracheal tube to enter main pipe entrance 4.Secondary duct entry 5 is arranged on the arc-shaped bend structure place of draw-in groove 3 front end eyeglasses 1, comprise and be arranged on two curved flanges 8 that upper and lower clamping plate place is outwards departed from backward gradually by eyeglass 1 front end, the lateral edges of two curved flanges 8 is the corresponding banking stop 9 that is respectively arranged with a mutual dislocation up and down, banking stop 9 is preferably triangle or trapezoidal, and be connected breach that the air supply pipe conduit is peeled off of formation between two banking stops 9 with the lateral edges of curved flanges 8 by its base.The lateral edges of upper and lower curved flanges 8 forms 10 °-15 ° angle respectively with upper and lower clamping plate edge, insert draw-in groove from secondary duct entry 5 rear portions thereby be conducive to endotracheal tube.The lower plate front end also is provided with a guide pad 10, endotracheal tube enters draw-in groove 3 when pushing ahead, guide pad 10 can push away endotracheal tube on the central axis of eyeglass 1, thereby makes the doctor can see the front end of endotracheal tube by the optical visible system, smoothly endotracheal tube is inserted glottis.
During normal oral trachea cannula, endotracheal tube is inserted the draw-in groove 3 from main pipe entrance 4 after lubricated in advance, observe whether to advance by view finder 11 and too before block the visual field, behind the general anesthesia induction, eyeglass 1 hits exactly directly over tongue from the oral cavity and inserts, the limit advances the laryngoscope limit to mention eyeglass 1, what make that the doctor can be along with eyeglass 1 deeply sees uvula and epiglottis, after glottis exposes, endotracheal tube in the draw-in groove 3 is advanced downwards, can see that tracheal tampon passes through glottis, in case the cover capsule passes through glottis, just can give sleeve bag gas-filling, and connect the conduit to the breathing loop.With peeling method endotracheal tube is withdrawed from the draw-in groove 3 subsequently and finish intubate.
During nasal trachea cannula, endotracheal tube inserts from the nostril after lubricated, eyeglass 1 enters from the oral cavity, endotracheal tube front end and eyeglass 1 meeting and after, endotracheal tube is pushed draw-in groove 3 front portions between two curved flanges 8 of secondary duct entry 5, two banking stops 9 can prevent that endotracheal tube breaks away from from draw-in groove 3, glottis advances glottis with conduit after exposing, concrete operations are identical with oral trachea cannula, after conduit is fixing by the cover capsule, endotracheal tube is peeled off from the breach between two banking stops 9 finish intubate.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model; above-mentioned embodiment and description are principle of the present utility model; this utility model also has various changes and modifications under the prerequisite that does not break away from this utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that this utility model requires is defined by claims and equivalent thereof.
