Detailed Description

To further illustrate the various embodiments, the utility model provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the utility model and, together with the description, serve to explain the principles of the embodiments. Those skilled in the art will appreciate still other possible embodiments and advantages of the present invention with reference to these figures. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The utility model will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 to 4, the present embodiment provides a laryngoscope blade, which includes a laryngoscope blade body, wherein the laryngoscope blade body has an inner cavity 10, a tongue pressing portion 20 located in front of the inner cavity 10, and an intubation guide portion 30 located at the side of the inner cavity 20; the tongue presser 20 functions to press the tongue during insertion, making the insertion smoother. The rear end of inner chamber 10 is open end 11, and its front end is transparent blind end 12, still be provided with leaded light post 50 in the inner chamber 10, leaded light post 50 butt is in the inboard of transparent blind end 12.

In use, the laryngoscope blade is inserted into the patient's larynx and the trachea is inserted at the position of the intubation guide 30 to assist the patient in ventilating and breathing. The laryngoscope is inserted into the inner cavity 10 through the opening end 11 of the inner cavity 10, light emitted by a light source of the laryngoscope can be condensed through the light guide column 50 and then emitted out through the transparent closed end 12, the irradiated part is clearer, and the abnormity of astigmatism and glaring is effectively eliminated.

Further, the transparent closed end 12 has a limiting groove (not shown), and the light guide pillar 50 is disposed in the limiting groove, so that the light guide pillar 50 can be well fixed, and is not easy to deviate.

Furthermore, the surface of the tongue depressor 20 is provided with an anti-reflection structure, so that the emitted light can be effectively prevented from reflecting after being irradiated on the surface of the tongue depressor 20, and the imaging picture quality of the laryngoscope is higher.

More specifically, in the dormitory building, the anti-reflection structure is implemented by directly providing the surface of the tongue depressing part 20 as a rough surface, such as by sanding, without additionally adding other materials. Of course, in other embodiments, the tongue-depressing part may be coated with an antireflection layer on the surface thereof.

Further, set up on the laryngoscope lens body and link up from the rear end to the air vent 40 of front end, so set up, at laryngoscope lens insertion in-process (the trachea has not inserted yet this moment), can assist through air vent 40 and ventilate, avoid having the sense of suffocation at insertion in-process patient, can be fine alleviate patient's pressure.

Further, the vent hole 40 is opened between the side wall of the inner cavity 10 and the cannula guide 30, and is disposed at the position, which has the least influence on other structures and the best effect. Of course, in other embodiments, a vent hole or the like may be drilled in the sidewall of the inner cavity 10.

Further, the intubation tube guide 30 is provided with a guide groove 31, and the guide groove 31 is arranged to guide the trachea and prevent sideslip; the insertion of the trachea is smoother.

Further, the laryngoscope blade body is a light-transmitting body, namely the laryngoscope blade body is integrally prepared (for example, integrally injection-molded by an injection molding mode) by a light-transmitting material; is convenient for preparation.

More specifically, a scale (not shown) is disposed on a side wall (in this embodiment, the upper side wall 13) of the inner cavity 10; through the design of scale, when inserting the laryngoscope, can show the scale on the image picture, confirm the inserted position of laryngoscope through the scale, accuracy and efficiency are higher.

Of course, in other embodiments, the laryngoscope blade body may be of a structure that is not completely transparent, so long as the transparent closed end 12 is guaranteed to be of a transparent structure.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
