Description

Technical Field

[0001] The invention relates to the technical field of laryngoscopes, and in particular to a laryngoscope blade with a handle and a laryngoscope assembly. Background Art

[0002] The laryngoscope assembly includes: a laryngoscope blade and a camera pipe. The laryngoscope blade is provided with a pipe sleeve. When in use, the camera pipe is directly inserted into the pipe sleeve, and the camera set in the camera channel can be inserted into the throat together, and the camera can capture the scene in the throat. In order to ensure medical hygiene conditions, the laryngoscope blades are mostly disposable laryngoscope blades, and the disposable laryngoscope blades are mostly formed by transparent plastic through molds. In view of the current arc core pulling process, the pipe sleeve of the disposable laryngoscope blade must be made into an arc shape, because the non-arc pipe sleeve cannot be made by arc core pulling; however, from the perspective of ergonomics, the oral entrance is in a straight line with the pharynx, and a tongue depressor with a non-arc structure is more in line with the actual situation; therefore, the existing disposable laryngoscope blades are mostly provided with a non-arc tongue depressor on a circular arc pipe sleeve.

[0003] Furthermore, to protect the camera and hygiene, the camera is filmed through the front end seal of the pipe sleeve. In order to ensure the normal production and application of the laryngoscope blade pipe, the laryngoscope blade pipe must have sufficient strength. The thickness of the pipe sleeve must generally reach more than 0.8 mm. Transparent plastic of this thickness has poor heat conduction. Therefore, the front end seal of the pipe sleeve is prone to water mist in the throat, which seriously affects the imaging effect of the camera.

[0004] Furthermore, most of the existing disposable laryngoscope blades are directly connected to the reusable handles by snap-fitting. However, due to production tolerances, a small amount of disposable laryngoscope blades produced in large quantities are easily mixed in and cannot be perfectly connected to the reusable handles. The disposable laryngoscope blades are easily loosened from the handle, seriously affecting their use.

[0005] Therefore, the prior art has defects and needs to be improved. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a laryngoscope blade with a handle and a laryngoscope assembly, so as to reduce the difficulty of producing the laryngoscope blade and enable one laryngoscope blade to correspond to multiple camera channels for easy application.

[0007] The technical solution of the present invention is as follows: a snake bone laryngoscope blade with a handle is provided, comprising: a handle, a snake bone plate connected to the handle, and a front end plate connected to the snake bone plate; the snake bone plate is provided with a pipeline groove and a plurality of bending grooves, the pipeline groove extends from the handle to the front end plate, the bending groove spans the snake bone plate, and the angle between the bending groove and the pipeline groove is 85°-95°; the cross section of the pipeline groove is T-shaped. The snake bone plate can be bent, and the camera pipe can be inserted into the T-shaped pipeline groove, so it can adapt to a variety of different camera pipes, which greatly facilitates the application. At the same time, during production, the snake bone laryngoscope blade with a handle can be molded in a straight line, without the need for a complex disposable laryngoscope production mold, which facilitates the design of the mold and reduces the difficulty of operation. The shape of the snake bone laryngoscope blade is directly shaped through the camera pipe to meet the application requirements. The self-contained handle can effectively avoid the problem of loosening of the snake bone laryngoscope blade, and avoids the influence of looseness on the use. Since the snake bone plate can be bent, it can adapt to camera pipes of various shapes, which greatly facilitates the application, reduces the inventory of different laryngoscope blades, and effectively saves costs.

[0008] Furthermore, the handle is hollow inside, and the hollow handle can facilitate the passage of the camera tube, making it easy to use.

[0009] Furthermore, the snake bone plate includes: a bottom plate, a plurality of left vertical pieces connected to the left side of the bottom plate, a plurality of right vertical pieces connected to the right side of the bottom plate, a left cover piece connected to the left vertical piece, and a right cover piece connected to the right vertical piece; the left cover piece and the right cover piece are both arranged above the bottom plate; the bottom plate, the left vertical piece, the left cover piece, the right vertical piece, and the right cover piece form a T-shaped groove, and there are curved grooves between two adjacent left cover pieces and between two adjacent right cover pieces.

[0010] Furthermore, the handle, the snake bone plate and the front end piece are integrally formed.

[0011] Furthermore, the snake-bone laryngoscope blade with a handle also includes: a transparent film covering the pipeline groove and the curved groove. The film can be a highly transparent and highly elastic TPU film. Since the film is very thin, the thickness is generally less than 0.2 mm, so it has an excellent heat transfer effect. Therefore, the film inserted into the throat is not prone to water mist, which effectively ensures the imaging effect of the camera. Preferably, the transparent film covers the entire snake-bone plate.

[0012] Furthermore, the present invention also provides a laryngoscope assembly, comprising: the aforementioned snake-bone laryngoscope blade with a handle, and a camera pipe; the camera pipe comprises: a fixing plate, a pipe body connected to the fixing plate, and a hollow tube connected to the fixing plate and the pipe body respectively; the hollow tube is connected to the pipe body; the fixing plate and the pipe body are inserted into the pipe groove. The camera pipe can first pass through the hollow handle and then into the pipe groove. Since the snake-bone plate can be bent, it can be compatible with camera pipes with different curvatures, which greatly facilitates the application.

[0013] Furthermore, the front end of the fixing plate is provided with a convex strip, the inner side of the front end piece is provided with a groove, and the convex strip matches the groove. The convex strip can be inserted into the groove to prevent the snake bone camera pipe from being easily loosened.

[0014] By adopting the above scheme, the present invention provides a snake bone laryngoscope blade with a handle and a laryngoscope assembly. The snake bone plate can be bent, and the camera pipe can be inserted into a T-shaped pipe groove, so it can adapt to a variety of different camera pipes, which greatly facilitates the application. At the same time, during production, the snake bone laryngoscope blade with a handle can be demolded in a straight line, without the need for a complex disposable laryngoscope production mold, which facilitates the design of the mold and reduces the difficulty of operation. The shape of the snake bone laryngoscope blade is directly shaped through the camera pipe to meet the needs of the application. The built-in handle can effectively prevent the problem of the snake bone laryngoscope blade from loosening, avoiding the influence of loosening on use. BRIEF DESCRIPTION OF THE DRAWINGS
