Background technology
On clinical medicine, the anesthesia doctor generally needed patient is carried out tracheal intubation use equipment such as anesthetic machine, respirator to patient before, i.e. endotracheal tube that is used for connection device of trachea interpolation of past patient.When carrying out tracheal intubation, need the support of catheterization equipment, common equipment mainly contains anesthetic laryngoscope.After the doctor uses anesthetic laryngoscope that the glottis of human body is exposed, again endotracheal tube is inserted into glottis after.For traditional anesthetic laryngoscope of majority, laryngoscope blade directly is connected with handle, and as the critical piece of anesthetic laryngoscope, the effect of playing main support effect and guiding or producing illuminating ray, such laryngoscope blade cost is higher, generally do not use, that is: be re-used in a plurality of patients, before each the use, all will carry out disinfection as medical disposable material.Because laryngoscope blade complex-shaped may have the inadequate problem of sterilization when sterilization, and sterilization is more consuming time, as application number be 200620062838.4, name is called the Chinese patent of " novel laryngoscope blade ".Some are also arranged now as disposable laryngoscope blade, more especially the disposable laryngoscope blade that is used for the electronic dental anesthesia laryngoscope, the phenomenon that all may have laryngoscope blade indirect illumination light and cause the image quality of the photographic head on the laryngoscope to be interfered, some also occur and solved the multiple design of this phenomenon, every kind of design all has the characteristics of oneself, as application number be 200680050977.8, name is called the Chinese patent application of " laryngoscope blade ".
Summary of the invention
The object of the present invention is to provide a kind of disposable laryngoscope blade that is used for the electric video anesthetic laryngoscope, by the forward inner structure of advancing by leaps and bounds of laryngoscope blade to eliminate laryngoscope blade to the reflection of illuminating ray and then improve the image quality of camera system.
To achieve these goals, the present invention is achieved through the following technical solutions: a kind of laryngoscope blade, mainly by laryngoscope blade main body, spatula, endotracheal tube guiding groove, fixedly ear, inner chamber are formed, wherein: spatula is connected with the front end of laryngoscope blade main body, the endotracheal tube guiding groove is positioned at the lateral margin of laryngoscope blade main body, inner chamber is positioned at the inside of laryngoscope blade main body, that end that is positioned at the laryngoscope blade body front end of inner chamber seals, that end that is positioned at laryngoscope blade main body tail end of inner chamber is open, and fixedly ear is connected with the tail end of laryngoscope blade main body; It is characterized in that: the front end in the laryngoscope blade main body is provided with camera window, camera window is advanced by leaps and bounds toward inner chamber, produce recessed blind hole to inner chamber in the front end surface of laryngoscope blade main body, a side that is positioned at inner chamber at the front end of laryngoscope blade main body produces protruding round platform to inner chamber, does not have through hole on camera window.
Above-mentioned laryngoscope blade, the laryngoscope blade main body is observed curved from the side, and spatula is to this arcual center position bending.
Above-mentioned laryngoscope blade fixedly has a through hole on the ear.
Above-mentioned laryngoscope blade is an integrated molding.
Above-mentioned laryngoscope blade adopts the transparent material manufacturing.
The present invention structurally uses the inner chamber that offers anesthetic laryngoscope assembling and use, fixing ear, thereby realize the quick assembling or the dismounting of laryngoscope blade and anesthetic laryngoscope, especially use the inner camera window structure of advancing by leaps and bounds to eliminate laryngoscope blade to the reflection of illuminating ray and then improve the image quality of camera system at the front end of laryngoscope blade main body, thereby possess easy to operate and the high beneficial effect of image quality, so the present invention have significant substantive progressive.

The specific embodiment
Enumerating a specific embodiment below also is specifically described the specific embodiment of the present invention in conjunction with the accompanying drawings.
As Fig. 1-shown in Figure 4, laryngoscope blade 11 is specific embodiments of the present invention, laryngoscope blade 11 is to use the PC plastics integrated molding of highly transparent to make, laryngoscope blade 11 is mainly by laryngoscope blade main body 1, spatula 2, endotracheal tube guiding groove 3, fixedly ear 4, inner chamber 5 is 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, endotracheal tube guiding groove 3 is positioned at the lateral margin of laryngoscope blade main body 1, 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, 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, does not have through hole on camera window 7.
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.
As 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 laryngoscope blade 11 can be unloaded from anesthetic 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 anesthetic 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 anesthetic laryngoscope 6 work, 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 enters 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 communication process middle part light splitter before injecting laryngoscope blade 11 and in laryngoscope blade 11 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, it is few that reflected light can enter the amount of photographic head at last, can not produce and disturb the imaging of photographic head, on display, do not observe flare (that is dazzle).
