Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a fully enclosed laryngeal lens and a video laryngoscope. Background Art
[0002] With the progress of medical device technology, laryngoscopes have become essential medical devices in hospitals. Existing laryngoscopes include a handle and a lens. The lens is installed on a matching handle to ensure that the lens is fixedly installed on the handle. The handle is reused multiple times. The lenses include large-sized lenses, medium-sized lenses, and small-sized lenses. Large-sized lenses are mostly used for adult males, medium-sized lenses are mostly used for adult females, and small-sized lenses are mostly used for children and adolescents. When in use, the patient is placed in a supine position with the head tilted as far back as possible. The laryngoscope is held in the left hand and inserted into the oral cavity along the right corner of the mouth; the lens is slowly pushed until it reaches the root of the tongue until the epiglottis is seen. The tracheal catheter is held in the left hand and inserted into the groove of the tongue depressor along the laryngeal lens. During the use process, laryngeal lenses and handles made of metal materials are used. However, their materials are expensive, and there is a phenomenon of cross-infection between patients caused by incomplete disinfection.
[0003] In order to meet the needs of some patients with weakened immune systems and the requirements of nosocomial infection control, disposable laryngeal lenses have emerged. However, most of the existing disposable laryngeal lenses cannot protect the handle part of the laryngoscope. After use, if the laryngoscope handle cannot be completely disinfected, there is still a risk of infection, which poses certain potential hazards to both doctors and patients. In view of the above defects, this application is proposed. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a fully enclosed laryngeal lens and a video laryngoscope, which can comprehensively protect the rod body and eliminate the risk of cross-infection between patients or between patients and doctors.
[0005] To solve the above problems, the utility model provides a fully enclosed laryngeal lens, including a rod body accommodating part, a connecting wire accommodating part, and a lens accommodating part. The rod body accommodating part has an open end for inserting a camera assembly. An outward convex structure with a larger diameter is provided on the rod body accommodating part. The outward convex structure is used to prevent pollutants from entering the open end. A receiving groove and a guiding inclined surface are provided in the lens accommodating part. The receiving groove is used to accommodate the camera module, and the guiding inclined surface is used to assist the camera module to enter the receiving groove.
[0006] According to an embodiment of the utility model, the outward convex structure is provided at the end of the rod body accommodating part.
[0007] According to an embodiment of the utility model, the diameter of the outward convex structure gradually decreases from the open end to the other end, presenting a flared structure.
[0008] According to an embodiment of the present utility model, a rod body fixing structure is provided in the rod body accommodating portion. After the camera assembly is placed, the rod body fixing structure is used to fix it.
[0009] A video laryngoscope includes a camera assembly and the above-mentioned all-inclusive laryngeal lens. The camera assembly includes a rod body, a connecting line, and a camera module.
[0010] According to an embodiment of the present utility model, the shape of a part of the end position of the rod body fits the shape of the inner cavity of the convex structure, achieving the effect of stably maintaining the position after placement. A shooting button is provided at the end of the rod body, and the shooting button should be exposed after implantation for easy operation.
[0011] According to an embodiment of the present utility model, the connecting line is a flexible connecting line, which is convenient for the placement of the camera assembly.
[0012] It should be noted that a connecting line with a certain hardness can also be used.
[0013] According to an embodiment of the present utility model, an elastic locking mechanism is provided on the rod body. The rod body fixing structure is a groove. The elastic locking mechanism enters the groove to achieve the locking effect on the rod body. The elastic locking mechanism preferably uses a spring ball. The elastic locking device and the groove cooperate with each other to achieve reversible locking. In this way, the all-inclusive laryngeal lens can be conveniently fixed to the rod body and can also be easily removed.
[0014] According to an embodiment of the present utility model, a plurality of groups of the elastic locking mechanism and the groove are provided, such as two groups or more than two groups.
[0015] According to an embodiment of the present utility model, a connector interface and a connector are provided at the outer end of the rod body.
[0016] The beneficial effects of the present utility model are as follows: through the setting of the all-inclusive laryngeal lens, the rod body can be comprehensively protected, and the risk of cross-infection between patients or between patients and doctors can be eliminated. And by providing a convex structure on the all-inclusive laryngeal lens, during the treatment process, if the patient vomits, the convex structure can largely prevent pollutants from contaminating the upper end of the handle, further avoiding the problem of cross-infection.
[0017] A connector interface is left on the camera assembly, which can be connected to a small screen, a large screen, a wired transmission module, a wireless transmission module or other devices to realize multi-scenario applications of the product. Description of the Drawings

The rod body accommodating portion 24, the connecting wire accommodating portion 25, and the lens accommodating portion 26 are generally integrally formed, with an inner cavity 21 formed inside, and together they form the fully enclosed laryngeal lens. Among them, the rod body accommodating portion 24 is used to accommodate the rod body 11 of the camera module, the connecting wire accommodating portion 25 is used to accommodate the connecting wire 12, and the lens accommodating portion 26 is used to accommodate the camera module 13.
[0032] The rod body receiving portion 24 has an open end for inserting the camera assembly. An outwardly convex structure 23 is provided on the rod body receiving portion 24. The diameter of the outwardly convex structure 23 is larger than the diameter of the remaining positions of the rod body receiving portion 24, thereby forming a position convenient for grasping, facilitating the operation of medical staff. Most importantly, the outwardly convex structure 23 can be used to prevent pollutants from entering the open end. Preferably, in this embodiment, the outwardly convex structure 23 is provided at the end of the rod body receiving portion 24, and the diameter of the outwardly convex structure 23 gradually decreases from the open end to the other end, presenting a flared shape. During the treatment process, if the patient vomits, the setting of the outwardly convex structure 23 can largely prevent pollutants from contaminating the upper end of the handle and avoid the problem of cross-infection.
[0033] As Figure 5 , a receiving groove 211 and a guiding inclined surface 212 are provided in the lens receiving portion 26. The guiding inclined surface 212 is provided at the front end of the receiving groove 211. The receiving groove 211 is matched with the camera module.
