The specific embodiment
Enumerate a specific embodiment below and combine accompanying drawing that the specific embodiment of this utility model is specified.
Like Fig. 1-shown in Figure 4; Laryngoscope blade 11 is specific embodiments of this utility model, and laryngoscope blade 11 is to use the PC plastics integrated molding of highly transparent to make, and laryngoscope blade 11 is mainly by laryngoscope blade main body 1, spatula 2, endotracheal tube guiding groove 3, fixedly ear 4, inner chamber 5 are formed; Wherein: laryngoscope blade main body 1 is as the main support structure of laryngoscope blade 11; Spatula 2 is connected with the front end of laryngoscope blade main body 1, and endotracheal tube guiding groove 3 is positioned at the lateral margin of laryngoscope blade main body 1, and inner chamber 5 is positioned at the inside of laryngoscope blade main body 1; That end that is positioned at laryngoscope blade main body 1 front end of inner chamber 5 seals; That end that is positioned at laryngoscope blade main body 1 tail end of inner chamber 5 is open, and fixedly ear 4 is connected with the tail end of laryngoscope blade main body 1, and a through hole is fixedly arranged on the ear 4; Front end in laryngoscope blade main body 1 is provided with camera window 7; Camera window 7 is advanced by leaps and bounds toward inner chamber 5; Produce recessed blind hole to inner chamber 5 in the front end surface of laryngoscope blade main body 1, a side that is positioned at inner chamber 5 at the front end of laryngoscope blade main body 1 produces protruding round platform to inner chamber 5, on camera window 7, does not have through hole.
As shown in Figure 4, laryngoscope blade main body 1 is observed curved from the side, and spatula 2 is to this arcual center position bending.
Like Fig. 5-shown in Figure 7, laryngoscope blade 11 is assemblied on a anesthetic laryngoscope of being produced by my company 6, and the practical application of laryngoscope blade 11 has been described.After the assembling, anesthetic laryngoscope 6 stretches into the inner chamber 5 of laryngoscope blade 11, and fixedly the through hole on the ear 4 snaps on the fixedly step (not shown in figures) on the anesthetic laryngoscope 6, and laryngoscope blade 11 just has been locked on the anesthetic laryngoscope 6.After finishing using, user fixedly ear 4 pushes away forward outward, and the through hole on the fixing ear 4 is separated and can laryngoscope blade 11 be unloaded from numb acid anhydride laryngoscope 6 with fixedly step (not shown in figures) on the anesthetic laryngoscope 6.
As shown in Figure 7, because the camera window 7 on the laryngoscope blade 11 advances by leaps and bounds in the inner chamber 5, after laryngoscope blade 11 assembles with anesthetic laryngoscope 6, the advance by leaps and bounds step 12 of past indent of numb acid anhydride laryngoscope 6 front ends of camera window 7; The optical fibre channel 8 of anesthetic laryngoscope 6 front ends is arranged between the periphery and step 12 of anesthetic laryngoscope 6 front ends; During 6 work of fiber crops acid anhydride laryngoscope; Illuminating ray L1 penetrates from the optical fiber (not shown in figures) in the optical fibre channel 8; The front end of laryngoscope blade 11 and the zone between the camera window 7 are crossed in transmission, and imaging light L2 reflects and transparent baffle 10 through camera window 7, step 12 and photographic head 9 fronts gets in the photographic head 9 from illuminated tissue; The exit facet of illuminating ray L1 (promptly; The surface of emission of optical fiber) with the outer surface of transparent baffle 10 not at grade, and the exit facet of illuminating ray L1 is before the outer surface of transparent baffle 10, illuminating ray L1 before injecting laryngoscope blade 11 and laryngoscope blade 11 in the middle part of the communication process light splitter can reflect; Because the camera window 7 of laryngoscope blade 11 is advanced by leaps and bounds in the step 12 of anesthetic laryngoscope 6 front ends; Reflected light is isolated, and it is few that reflected light can get into the amount of photographic head at last, can not produce the imaging of photographic head and disturb; On display, do not observe flare (that is dazzle).
