[0002] Vessels refer to all containers used to hold items or objects. They can be made of different materials and in various shapes to meet different needs. In the daily diagnostic and nursing care of hematology departments, it is often necessary to place medical instruments in vessels. After use, vessels need to be disinfected and cleaned promptly to prevent residual bacteria or impurities from contaminating the placed medical instruments and affecting their use.

[0003] A Chinese patent with publication number CN216855308U discloses a blood instrument sterilization device, including a sterilization table and a rotating mechanism. The rotating mechanism is located at the top center of the sterilization table and has a cleaning mechanism. The top of the sterilization table has a first sterilization tank, a second sterilization tank, and a third sterilization tank. A first connecting pipe is provided between the first and second sterilization tanks, and a second connecting pipe is provided between the second and third sterilization tanks. Pumps and valves are installed on both the first and second connecting pipes. Grooves are formed on the inner walls of both sides of the first sterilization tank, and an infrared transmitter and an infrared receiver are respectively installed in the two grooves. This invention not only thoroughly sterilizes the instruments but also maximizes the utilization rate of the sterilizing solution, exhibiting a high degree of automation.

[0065] In this embodiment, the laser emitting sensor 38 and the laser receiving sensor 39 work together to facilitate the spraying device 7 in detecting the specific location of the placement device 9.

[0066] Working principle: When needed, medical staff open the cover plate 4. At this time, the electric rotating shaft 22 rotates to bring the spray device 7 and the electric telescopic rod 6 close to the top of the cleaning chamber 2. Then, according to the needs, multiple support devices 8 are installed at a suitable height through the cooperation of the mounting plate 802 and the limiting groove 25. Then, the U-shaped hanging plates 902 at both ends of the storage device 9 are placed on the L-shaped plate 801 for support. The storage device 9 can be set as a single layer or multiple layers.

[0067] Then, medical staff can place the instruments to be sterilized directly into the placement device 9, close the cover 4, and select the cleaning program or cleaning duration using the control button 37 to start the device. The first slider 501 will slide to both ends of the chute, and then the electric rotating shaft 22 will drive the electric telescopic rod 6 and the spray device 7 to make an arc-shaped movement, so that the spray device 7 is perpendicular to the placement device 9. Then, the second drive motor 505 will drive the threaded rod 503 to rotate, causing the second slider 504 to be located in the middle of the threaded rod 503. The electric telescopic rod 6 will extend, causing the spray device 7 to descend. Then, the laser emitting sensor 38 cooperates with the laser receiving sensor 39 on the outside of the placement device 9 to detect the first placement device 9 located above. Then, the first slider 501 slides towards the middle of the groove, so that the U-shaped tubes 701 on both sides close together and place the mesh plate 901 between the two U-shaped tubes 701. The second drive motor 505 is started to drive the second slider 504 to move horizontally left and right. At the same time, the disinfectant chamber 23 delivers disinfectant into the U-shaped tube 701 through the infusion tube 24, and the spray nozzle 702 sprays disinfectant to disinfect the utensils in the mesh plate 901.

[0068] At the same time, the first drive motor 13 is started, which drives the arc scraper 11 and the dividing blade to rotate, collect and divide the disinfection waste liquid and fixed impurities in the arc groove 10, and start the pump body 16 to divert and collect the impurities and disinfection waste liquid in the diversion groove into the waste liquid tank 15.

[0069] After the containers in the first mesh plate 901 are disinfected, the second slider 504 returns to the initial middle position. Then, the first slider 501 slides to both ends in the chute, and the electric telescopic rod 6 extends to drive the spray device 7 downward until the next mesh plate 901 is detected, and the above disinfection and cleaning work is repeated. If the electric telescopic rod 6 is extended to the end and the placement device 9 is not detected, it returns to the top. At the same time, the electric rotating shaft 22 moves the electric telescopic rod 6 and the spray device 7 close to the top of the cleaning chamber 2. Then, the drying device and the ultraviolet germicidal lamp 33 are started to perform drying and sterilization treatment, thereby achieving the final cleaning, disinfection and sterilization purpose.

[0070] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
