Description

Technical Field

[0001] The utility model relates to a waterproof structure for a laryngoscope, in particular to a waterproof structure for a telescopic video laryngoscope. Background Art

[0002] At present, with the upgrading of video laryngoscope technology, lens styles that can adjust the length and angle of the lens have gradually emerged. Especially under the concept of combining rigid endoscopes and flexible endoscopes, the emergence of telescopic flexible endoscopes based on rigid endoscopes has greatly solved the clinical problems of difficult airways and difficult intubation, avoided the evolution of difficult airways into emergency airways, and benefited patients.

[0003] However, this technology involves problems of waterproofing and disinfection. If the telescopic part of the flexible endoscope cannot be effectively sealed, patient secretions, sputum, etc. will flow into the rigid endoscope part, damaging the components of the telescopic laryngoscope or causing the motor to short - circuit. Therefore, it is particularly important to develop a reliable and effective waterproof structure that does not affect its telescoping. In addition, if the telescopic flexible endoscope needs to be disinfected repeatedly, it will not only increase the workload of medical staff, but also the telescopic part is not easy to be completely disinfected, and repeated brushing will greatly reduce the service life. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a waterproof structure for a telescopic video laryngoscope to solve the technical problems that the existing laryngoscope does not have a waterproof function and the telescopic structure is not easy to be disinfected.

Detailed Description of the Embodiment

[0016] The embodiments of the utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model and should not be construed as a limitation of the utility model.

[0017] Embodiment 1 of the utility model: As Figures 1 - 3 shown, a waterproof structure of a telescopic video laryngoscope includes a lens tube 1 and a camera telescopic assembly 2. One end of the lens tube 1 is fixedly connected to one end of a corrugated pipe 3, and the other end of the corrugated pipe 3 is fixedly connected to the end of the camera telescopic assembly 2.

[0018] The mirror tube 1 and the camera telescopic assembly 2 are both prior arts. The mirror tube 1 is usually a round tube, and the camera telescopic assembly 2 usually includes a camera 4, a snake bone tube 12, and a connecting tube 5. One end of the connecting tube 5 is connected to a driving device disposed within the handle of the video laryngoscope, and the other end of the connecting tube 5 is connected to the camera 4 through the snake bone tube 12. The snake bone tube 12 is connected to the driving device through a wire. The driving device can achieve the telescoping of the camera 4 by pushing or pulling the connecting tube 5, or can adjust the bending degree of the snake bone tube 12 by driving the wire to change the working angle of the camera 4. Since the camera 4, the connecting tube 5, the snake bone tube 12, and the driving device are all prior arts, the specific structures and working principles thereof will not be elaborated in this embodiment.

[0019] Through the arrangement of the corrugated tube 3, liquids (such as secretions, sputum, disinfectant water, etc.) cannot enter the mirror tube 1 through the gap between the outer wall of the camera telescopic assembly 2 and the inner wall of the mirror tube 1, thereby effectively protecting electrical components such as motors within the mirror tube 1 and ensuring the service life of the laryngoscope.

[0020] Due to the arrangement of the corrugated tube 3, the corrugated tube 3 has the functions of telescoping and bending and will not interfere with the normal extension and angle adjustment of the telescopic video laryngoscope.

[0021] In a specific embodiment, a first connecting round tube 6 is formed at one end of the corrugated tube 3, and a second connecting round tube 7 is formed at the other end of the corrugated tube 3. The first connecting round tube 6 is inserted into the mirror tube 1, and the second connecting round tube 7 is sleeved on the outer wall of the camera 4.

[0022] The first connecting round tube 6 and the inner wall of the mirror tube 1 can be connected by a direct plug-in method or a threaded connection method. When using the direct plug-in method, food-grade glue is required for bonding and sealing. When using the threaded connection method, a sealing ring needs to be designed at the connection part.

[0023] The second connecting round tube 7 is sleeved on the camera 4. To prevent liquid leakage, it is preferably bonded with food-grade glue.

[0024] Embodiment 2 of the present utility model: As Figures 1 - 3 shown, on the basis of Embodiment 1, a tongue depressor main body 8 is detachably installed on the mirror tube 1 in this embodiment. The end of the tongue depressor main body 8 is fixedly connected to a transparent protective bag 9, which is an integrated design.

[0025] The tongue depressor main body 8 is a prior art, and it can be either a socket-type tongue depressor or a snap-fit tongue depressor. The innovation lies in the combination of the tongue depressor main body 8 and the transparent protective bag 9. The transparent protective bag 9 is sleeved outside the camera telescopic assembly 2 and the corrugated tube 3.

[0026] Furthermore, the transparent protective bag 9 is of a cylindrical structure, and the end of the transparent protective bag 9 away from the tongue depressor body 8 is a closed end. A limiting ring groove 10 is formed on the outer wall of the camera 4, and an elastic rubber ring 11 is fixedly arranged on the inner wall of the closed end of the transparent protective bag 9, and the elastic rubber ring is installed in the limiting ring groove 10.

[0027] The transparent protective bag 9 is preferably made of plastic material. After the tongue depressor body 8 is sleeved on the telescopic video laryngoscope, both the camera telescopic assembly 2 and the corrugated pipe 3 are covered in the transparent protective bag 9. Since the elastic rubber ring 11 is arranged inside the transparent protective bag 9, the transparent protective bag 9 will gather or unfold following the change of the position of the camera 4. The closed end of the transparent protective bag 9 can be closely attached to the end of the camera 4 without reflection, so that the camera 4 can capture clear images regardless of its position.

[0028] Through the arrangement of the transparent protective bag 9, the camera 4 does not directly contact the patient, so there is no need for disinfection treatment after use. Just replace the new tongue depressor body 8 and transparent protective bag 9 during the next work. The tongue depressor body 8 and the transparent protective bag 9 are of a disposable design, which not only plays a role in secondary waterproofing, but also solves the problem of incomplete disinfection of the telescopic video laryngoscope.

[0029] The structure, features and function effects of the present utility model have been described in detail based on the embodiments shown in the drawings. The above is only the preferred embodiment of the present utility model, but the present utility model is not limited to the implementation scope shown in the drawings. Any changes made according to the concept of the present utility model, or modified into equivalent embodiments with equivalent changes, still within the spirit covered by the description and drawings, shall be within the protection scope of the present utility model.
