Therefore, they cannot be understood as limitations on the present invention.

[0033] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0034] Example 1

[0035] like Figure 1-5 As shown, the utility model provides a cross-infection-preventing respiratory endoscopy device, comprising a handle 1, a lens 602 fixedly connected to the handle 1, a protective component mounted on the handle 1, a connecting component for connecting the handle 1 and the wrapping sleeve 2, and a wrapping component arranged in the connecting component.

[0036] By providing a through slot for the lens 602 to pass through in the connecting assembly, the wrapping assembly is divided into a protective component and a defogging component, the protective component is provided as a wrapping sleeve 2 inserted in the through slot, the heating ring 201 in the defogging component is fixedly installed in the connecting assembly, the bottom surface of the heating ring 201 is fixedly connected to the thermal pad 202 arranged around the inner wall of the wrapping sleeve 2, one side of the heating ring 201 is connected to the outer wall of the connecting column 3, and a release paper 203 is provided on the heating ring 201 on this side, and the interior of the heating ring 201 is filled with a mixture of iron, vermiculite, activated carbon, salt, water, etc. The contact surface of the heating ring 201 and the release paper 203 is set as a breathable film, so that medical staff can insert the lens 602 into the wrapping sleeve 2 through the through slot, and then tear off the release paper 203 on the heating ring 201 to allow air to enter from the breathable film. The mixture inside the heating ring 201 produces an exothermic reaction under the action of oxygen in the air, and then the heat is conducted to the wrapping sleeve 2 through the thermal pad 202, so that the temperature of the wrapping sleeve 2 is increased, thereby adapting to the patient's internal body temperature and preventing the lens 602 from generating water mist due to the temperature difference, thereby affecting the examination of medical staff.

[0037] Furthermore, the defogger component also includes a curved lens 5 arranged on the bottom surface of the wrapping cover 2. By making the curved lens 5 recessed into the interior of the wrapping cover 2, even if water droplets condense on the curved lens 5, they will fall to the corners of the curved lens 5 due to gravity, and will not affect the medical staff's observation through the center of the curved lens 5. By arranging a water-absorbing ring 501 on the inner bottom surface of the wrapping cover 2, the water droplets falling to the corners of the curved lens 5 will be directly absorbed by the water-absorbing ring 501, and will not accumulate and then submerge the edge of the curved lens 5. By arranging an oleophobic layer formed by spraying nano-silicon dioxide on the curved lens 5 as raw material, the curved lens 5 has good light transmittance and hydrophobicity and oleophobicity, so that water droplets will not stay on the curved lens 5.

[0038] Specifically, a wiring port 6 is provided on the top surface of the handle 1, and one end of a connecting wire 601 is fixedly connected to the bottom surface of the handle 1, so that the other end of the connecting wire 601 is fixedly connected to the lens 602, and the lens 602 is electrically connected to the wiring port 6 through the connecting wire 601, so that medical staff can plug the data cable into the wiring port 6, and then transmit the image captured by the lens 602 through the connecting wire 601.

[0039] Example 2

[0040] Based on the first embodiment, specifically, Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the connecting assembly includes a connecting column 3 and a connecting block 402. By fixedly connecting the top of the connecting block 402 to the bottom of the handle 1, a connecting groove 301 is opened in the connecting column 3, and the connecting rod 4 is slidably connected in the connecting groove 301. A docking block 401 is set on the end of the connecting rod 4 close to the connecting block 402, and a docking groove 403 adapted to the docking block 401 is opened in the connecting block 402. A notch adapted to the docking block 401 is opened in the connecting column 3, and the docking block 401 is inserted into the docking groove 403, so that the through groove passes through the bottom surface of the connecting column 3 to the connection between the handle 1 and the connecting block 402, so that medical staff can pull the connecting rod 4 to make the docking block 401 enter the adapted notch, and then hold the handle 1 to insert the lens 602 into the package cover 2, and then push the connecting rod 4 back to drive the docking block 401 to be engaged in the docking groove 403, so that the connection between the handle 1 and the package cover 2 can be completed quickly and conveniently.

[0041] By providing a pull plate fixedly connected to the connecting rod 4 on the outside of the connecting rod 4, medical staff can pull the connecting rod 4 by holding the pull plate. Compared with the smooth outer wall of the connecting rod 4, the pull plate has a larger gripping area, and it is more convenient for medical staff to apply force when pulling the connecting rod 4.

[0042] Specifically, one end of the spring 405 is fixedly connected to the connecting rod 4, and the other end of the spring 405 is fixedly connected to the connecting groove 301. A chamfer 404 is opened on the docking block 401, so that when connecting the handle 1 and the wrapping sleeve 2, the connecting block 402 is directly inserted into the connecting column 3, and then the docking block 401 will shrink along the opening direction of the chamfer 404. At this time, the spring 405 will deform and accumulate elastic potential energy until the docking block 401 reaches the docking groove 403. The spring 405 will convert the previously accumulated elastic potential energy into kinetic energy and push the docking block 401 into the docking groove 403, thereby completing the connection between the handle 1 and the wrapping sleeve 2.

[0043] In addition, an anti-slip cover 101 is provided on the handle 1 , and limiting plates are provided at both ends of the handle 1 . The anti-slip cover 101 surrounds the outer wall of the handle 1 and is provided between the two limiting plates.

[0044] Working principle:

[0045] During installation, first hold the handle 1 and align the connecting block 402 with the connecting column 3 and insert it until the docking block 401 is engaged in the docking groove 403, and then the docking is automatically completed.

[0046] When in use, first plug the data cable into the connection port 6, then tear off the release paper 203 to allow air to enter from the breathable membrane. The mixture inside the heating ring 201 undergoes an exothermic reaction under the action of oxygen in the air, and then the heat is transferred to the wrapping cover 2 through the thermal pad 202, so that the temperature of the wrapping cover 2 is increased to adapt to the patient's body temperature, thereby preventing the lens 602 from generating water mist due to the temperature difference, thereby affecting the medical staff's examination.

[0047] After the inspection is completed, the pull plate is pulled to drive the docking block 401 to disengage from the docking groove 403, and the lens 602 is pulled out of the wrapping sleeve 2 by holding the handle 1 to complete the disassembly.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
