[0038] In this embodiment, a sleeve 22 is fixedly installed on the upper surface of the middle position of the top of the rotating cylinder 3. The sleeve 22 penetrates the outer surface of the fixed cylinder 2 and is rotatably installed therewith. A rotating shaft 21 is inserted into the interior of the sleeve 22. The rotating shaft 21 and the inner wall of the sleeve 22 are rotatably installed. The bottom end of the rotating shaft 21 penetrates the top wall of the rotating cylinder 3 and a turntable 16 is fixedly installed thereon. A circular groove is provided on the lower surface of the turntable 16. An ultraviolet lamp 17 is fixedly installed on the inner wall of the circular groove. A ventilation hole 18 is provided through the outer surface of the turntable 16 relative to the ultraviolet lamp 17.

[0039] The sleeve 22 is driven to rotate by the rotation of the rotating cylinder 3. Since the pin 31 inside the rotating shaft 21 is inserted into the slot 35 of the sleeve 22, the sleeve 22 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the turntable 16 to rotate. The turntable 16 drives the ultraviolet lamp 17 to rotate synchronously with the rotating cylinder 3, ensuring that the ultraviolet lamp 17 can fully disinfect and sterilize the medical instruments inside one of the disinfection chambers.

[0040] In this embodiment, the top of the rotating shaft 21 passes through the top of the sleeve 22 and is provided with a mounting groove. The inner walls of the mounting groove are fixedly installed with a clockwork spring 20. The other end of the clockwork spring 20 is fixedly installed with the upper surface of the fixed cylinder 2. The outer surface of the circumference of the rotating shaft 21 near the top is provided with a semicircular groove. The inner wall of the semicircular groove is slidably installed with a pin 31. The inner wall of the sleeve 22 is symmetrically provided with two card slots 35 matching the pin 31. The pin 31 is slidably installed with the inner wall of the card slot 35. The top of the pin 31 is fixedly installed with a square column 30.

The lower surface of the slider 34 is against the inclined surface and slidably installed.

[0041] The rotating shaft 21 drives the square column 30 to move through the pin 31, so that the square column 30 drives the slider 34 to move along the inclined surface. At this time, the slider 34 drives the pin 31 to slide out from the inside of the slot 35 through the square column 30. When the turntable 16 rotates 180°, the pin 31 slides out from the inside of the slot 35. At this time, under the action of the spring 20, the turntable 16 resets and moves, and the pin 31 is reinserted into another slot 35.

A support block 27 is fixedly installed on the upper surface of the fixed tube 2, and the other end of the first spring 28 is fixedly installed on the outer surface of the support block 27.

[0043] When the turntable 16 is reset, the mainspring 20 will also be fully extended. At this time, the mainspring 20 pushes the top rod 29, so that the top rod 29 drives the slide plate 26 to move, and the other end of the slide plate 26 completely slides out of the interior of the limiting sleeve 25. At this time, the medical staff can intuitively see whether the turntable 16 is fully reset, and then open the external gas filter to discharge the gas inside the disinfection chamber after disinfection and sterilization through the trachea and trachea connector 24 to avoid gas contamination of the air inside the supply chamber.

[0044] It should be noted that when the present invention is in use, the medical staff will hang the medical instruments that need to be taken to the supply room on the outer surface of the square slide bar 9 through the hook 10, and then close the sealing door 5. The sealing door 5 and the opening of the rotating cylinder 3 are provided with a sealing magnetic strip, and the sealing door 5 is sucked by the sealing magnetic strip. It should be noted that the two relative sealing doors 5 must be in a closed state. At this time, the two pressure sensors 19 transmit electrical signals at the same time, the servo motor 7 is unlocked, and the operator controls the servo motor 7 to rotate. At the same time, the ultraviolet lamp 17 is turned on, and the servo motor 7 drives the rotating cylinder 3 to rotate 180°, and the rotation of the rotating cylinder 3 drives the placement plate 8 to rotate. The placement plate 8 is driven by the gear 12 and the inner gear of the circular ring. The engagement of 11 makes it rotate itself, and the placement plate 8 drives the medical device to rotate through the square slide bar 9 and the hook 10. At the same time, the movement of the square slide bar 9 drives the driving column 15 to make a circular motion around the driving wheel 13, and the driving column 15 slides along the inner wall of the driving groove 14, so that it drives the square slide bar 9 to reciprocate up and down, staggers the position of the medical device, and at the same time makes the medical device shake. Through this device, when the medical device is irradiated and disinfected by the ultraviolet lamp 17, the outer surface of the medical device can be evenly irradiated, avoiding the outer surface from being blocked and unable to be disinfected, ensuring that the medical device can be used normally later; the rotation of the rotating cylinder 3 drives the sleeve 22 to rotate, and the pin 31 inside the rotating shaft 21 is inserted into the It is arranged in the card slot 35 of the sleeve 22, and the sleeve 22 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the turntable 16 to rotate, and the turntable 16 drives the ultraviolet lamp 17 to rotate synchronously with the rotating cylinder 3 to ensure that the ultraviolet lamp 17 can fully disinfect and sterilize the medical instruments in one of the disinfection chambers. The rotating shaft 21 drives the square column 30 to move through the pin 31, so that the square column 30 drives the slider 34 to move along the inclined surface. At this time, the slider 34 drives the pin 31 to slide out of the inside of the card slot 35 through the square column 30. When the turntable 16 rotates 180°, since the pin 31 slides out of the inside of the card slot 35, at this time, under the action of the spring 20, the turntable 16 resets and moves, and the pin 31 is reinserted into another card slot. 35, the ultraviolet lamp 17 can return to the external disinfection room after disinfection and sterilization through the device, so as to avoid the medical staff in the supply room from being irradiated by the light of the ultraviolet lamp 17 because they are not wearing protective clothing, thereby ensuring the safety of the medical staff; when the turntable 16 is reset, the clockwork 20 will also be fully stretched.
