A kind of hand-held laryngoscope of wounded dichroic liquid crystal display screen, comprise laryngoscope handle and display, what the front end of laryngoscope handle was provided with photographic head, photographic head removes atomizing nozzle, illuminating lamp, be provided with battery, mainboard in the laryngoscope handle, the laryngoscope handle is provided with switch outward, it is characterized in that: be provided with portable display on the laryngoscope handle, portable display links to each other with mainboard (11).
The described atomizing nozzle that removes removes atomizing nozzle and links to each other through the air inlet of air flue with the laryngoscope handle rear end above photographic head, and air flue is provided with gas generator.
Described photographic head is the colored CCD photographic head.
Described portable display is a chromatic liquid crystal screen.
Described rear end at the laryngoscope handle is provided with chromatic liquid crystal screen.
Be provided with the steering gear of four-way twin shaft between described chromatic liquid crystal screen and the laryngoscope handle.
The transverse axis of described four-way twin shaft steering gear is perpendicular to the laryngoscope handle, and the steering gear of four-way twin shaft is that rotating shaft can be spent in front and back rotation 0～270 with the transverse axis, but is rotating shaft left rotation and right rotation 0～90 degree with the longitudinal axis.
Described photographic head both sides respectively are provided with an illuminating lamp, and illuminating lamp is a fibre-optical cold light lamp.
Described battery is a lithium battery.
The beneficial effects of the utility model are: be provided with the colored CCD photographic head, looking away, video definition height; The rear end of laryngoscope handle is provided with chromatic liquid crystal screen, and is provided with the steering gear of four-way twin shaft, and is easy to use light and handy; Use illuminating lamp, to remove the atomizing nozzle observing effect good; The operator reduces the passive infection chance away from the patient oral cavity; The colored CCD photographic head moves forward in larynx front portion, non-blind area; Patient's head is in and smells the thing position during tracheal intubation, does not need extremely layback, reduces misery, and intubate is convenient smoothly; Structure is small and exquisite, the integrated level height.
