Description

Technical Field

[0001] This utility model relates to the field of lumen cleaning technology, and in particular to a lumen cleaning device for a disinfection supply center. Background Technology

[0002] In modern healthcare systems, the Central Sterile Supply Department (CSSD) is a crucial link in ensuring medical safety, responsible for the cleaning, disinfection, sterilization, and supply of medical devices. Tubular medical devices, due to their long, narrow internal channels and complex structures, are highly susceptible to the accumulation of contaminants such as blood and mucus, becoming breeding grounds for bacteria. Incomplete cleaning will affect the effectiveness of subsequent disinfection and sterilization, and may even lead to iatrogenic infections, threatening patient health.

[0003] Currently, traditional cleaning methods have many shortcomings. Manual scrubbing requires operators to use brushes to scrub deep into the tubes, which is labor-intensive, inefficient, and difficult to clean the hard-to-reach areas of long, curved, or rough-walled instruments. Operators also face a high risk of occupational exposure. While ultrasonic cleaning can improve efficiency, its method of using cavitation to remove dirt is not effective at cleaning stubborn biofilms and dried contaminants inside the tubes, and it cannot achieve targeted cleaning.

[0004] Existing automated cleaning equipment also has significant shortcomings. Some devices use a single spray cleaning method, which makes it difficult for the water flow to penetrate deep into the lumen, resulting in insufficient cleaning power. While some devices have rotation functions, their clamping devices lack adaptive adjustment capabilities, making it difficult to secure instruments of different sizes, thus affecting cleaning effectiveness and safety. Furthermore, most devices cannot intelligently adjust cleaning parameters according to the degree of instrument contamination, easily leading to resource waste or inadequate cleaning. With the development of medical technology, the number and types of lumen-type medical devices are constantly increasing, urgently requiring new cleaning devices to meet the demands for efficient, intelligent, and safe cleaning.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0031] As shown in the figure, a cleaning device for the pipeline of a disinfection supply center includes a housing 1 and a cleaning mechanism installed inside the housing 1. A start button 5 and a stop button 6 are installed on the outer wall of the housing 1 to facilitate the operator to start and stop the equipment. A controller 17 is installed in the water collection tank 3. In order to ensure that the controller 17 operates stably in a humid environment, the controller 17 is equipped with a waterproof shell to effectively avoid circuit failure caused by contact with water vapor.

[0032] The cleaning mechanism includes an upper cover plate 2 and a water collection tank 3, both of which are rectangular cavities with openings at the top. The upper cover plate 2 is detachably connected to the housing for placing and removing tubular instruments, while the water collection tank 3 is used for collecting and discharging wastewater during the cleaning process. The upper cover plate 2 has several evenly spaced insertion holes 4, and a clamping and rotating mechanism corresponding to each insertion hole 4 is located below the upper cover plate 2. This one-to-one correspondence design allows for the simultaneous cleaning of multiple tubular instruments, significantly improving cleaning efficiency.

[0033] Below the clamping and rotating mechanism, an electric lifting rod 8 is connected via a cleaning tube 7. The electric lifting rod 8 has a multi-stage telescopic structure, with its telescopic end fixedly connected to the bottom end of the cleaning tube 7, and its bottom end fixedly connected to the housing 1. Through the telescopic movement of the electric lifting rod 8, the lifting and lowering of the cleaning tube 7 can be precisely controlled, allowing it to smoothly extend into the interior of instruments of different lengths for cleaning.

[0034] A booster pump 9 is installed below the water collection tank 3. The controller 17 is electrically connected to the start button 5, stop button 6, electric lifting rod 8, and booster pump 9 to control the start and stop of each component. The booster pump 9 is connected to the cleaning pipe 7 through the water supply pipe 10. The water supply pipe 10 has a multi-section curved structure, and the curved ends of the water supply pipe 10 are equipped with telescopic pipes 14. The design of the telescopic pipes 14 allows the water supply pipe 10 to flexibly adapt to position changes during the lifting and lowering of the cleaning pipe 7, ensuring the stability of water flow transmission.

[0035] A first cleaning water bladder 11 is provided at the top of the cleaning pipe 7, and several second cleaning water bladders 12 are evenly arranged on the outer wall of the cleaning pipe 7. Spray holes 13 are provided between the second cleaning water bladders 12. The first cleaning water bladder 11 and the second cleaning water bladder 12 are made of corrosion-resistant flexible silicone. When water flows into the cleaning pipe 7, part of it will fill the first cleaning water bladder 11 and the second cleaning water bladder 12, causing them to expand and completely adhere to the inner wall of the pipe cavity, while the other part will be sprayed out from the spray holes 13 to rinse the inner wall of the pipe cavity in all directions.

[0036] Meanwhile, the water supply pipe 10 is equipped with an inlet pipe 15, which passes through the box 1 and is connected to an inlet switch to control the inflow of cleaning water; the drain pipe 16 of the water collection tank 3 also passes through the box 1 and is connected to a drain switch. After cleaning, the sewage in the water collection tank 3 can be discharged through the drain switch, and the controller 17 is electrically connected to the inlet switch and the drain switch to realize the automation of water flow control.

[0037] The clamping and rotating mechanism includes a square housing 18 and a rotating clamping base rotatably disposed within the square housing 18. The rotating clamping base includes an annular plate 19 integrally formed and extension plates 20 symmetrically disposed on both sides of the annular plate 19.

[0038] The square outer shell 18 is fixedly connected to the inner wall of the box 1. The square outer shell 18 has a through hole corresponding to the annular plate 19. The inner diameter of the annular plate 19 is equal to the diameter of the through hole. The outer diameter of the cleaning tube 7 is smaller than the diameter of the through hole, which ensures both the smooth rotation of the rotating clamping base and the smooth passage of the cleaning tube 7.

[0039] A clamping motor 21 is fixedly installed on the lower surface of the extension plate 20. An arc-shaped clamping plate 22 is fixedly installed at the output end of the clamping motor 21. The controller 17 is electrically connected to the clamping motor 21 and controls the operation of the clamping motor 21, which can drive the arc-shaped clamping plate 22 to clamp or release the tubular instrument.

[0040] To further improve the stability and accuracy of clamping, a sliding post 29 is provided on the other side of the clamping motor 21, and a groove 23 is provided on the square housing 18 to cooperate with the sliding post 29, ensuring the smoothness of the movement of the arc-shaped clamp 22. At the same time, a sensor transmitter 24 is provided on the inner side of one side of the arc-shaped clamp 22, and a sensor receiver 25 is provided on the inner side of the other side of the arc-shaped clamp 22. The controller 17 is electrically connected to the sensor transmitter 24 and the sensor receiver 25, and can automatically detect whether the instrument is clamped to the appropriate position.

[0041] In addition, a semi-circular rack 26 is provided on the annular plate 19, and a rotary motor 27 is fixedly provided on the square shell 18. A drive gear 28 that meshes with the rack 26 is fixedly provided at the output end of the rotary motor 27. During the cleaning process, the controller 17 is electrically connected to the rotary motor 27 to control its operation, drive the drive gear 28 to rotate, and thus make the annular plate 19 and the clamped tubular instruments rotate, so as to achieve all-round cleaning.

[0042] When using this device in practice:

[0043] 1. Instrument Placement and Fixation: Place the tubular instrument to be cleaned into the placement hole 4 of the upper cover plate 2. The controller 17 activates the clamping rotation mechanism, and the clamping motor 21 operates, driving the arc-shaped clamping plate 22 to move. The sensor transmitter 24 and sensor receiver 25 on the inner side of the arc-shaped clamping plate 22 cooperate. When the sensor detects that the tubular instrument has been clamped to the appropriate position, the clamping motor 21 stops operating, thus completing the fixation of the tubular instrument. At this time, the sliding column 29 on the other side of the clamping motor 21 slides within the sliding groove 23 of the square outer shell 18, ensuring the stability of the movement of the arc-shaped clamping plate 22.

[0044] 2. Cleaning process: Press the start button 5 on the outer wall of the housing 1. The controller 17 controls the electric lifting rod 8 to extend, driving the cleaning tube 7 to rise, so that the first cleaning water bag 11 and the second cleaning water bag 12 extend into the cavity of the instrument. At the same time, the booster water pump 9 starts, and water enters the water delivery pipe 10 through the water inlet pipe 15. Since the water delivery pipe 10 has a multi-section curved structure and the curved ends are equipped with telescopic pipes 14, it can adapt to the positional changes of the cleaning tube 7 during its ascent.

[0045] Water enters the cleaning pipe 7 through the water supply pipe 10. Part of the water enters the first cleaning water bladder 11 and the second cleaning water bladder 12, causing the bladders to expand and better conform to the inner wall of the tube. The other part of the water is sprayed out from the spray hole 13 between the second cleaning water bladders 12 to rinse the inner wall of the tube. At the same time, the rotary motor 27 starts, driving the drive gear 28 to rotate, which meshes with the semi-circular rack 26 on the annular plate 19, causing the rotary clamping base to rotate, thereby driving the tube instrument to rotate and achieving all-round cleaning.

[0046] 3. Cleaning Completion and Drainage: After cleaning is completed, press the stop button 6, the electric lifting rod 8 will retract, and the cleaning pipe 7 will be retracted; the controller 17 will control the drain switch to open, and the sewage in the water collection tank 3 will be discharged through the drain pipe 16; afterwards, the water inlet switch can be opened to clean the equipment and prepare it for the next use.

[0047] Therefore, this utility model adopts the above-mentioned cleaning device for the lumen of a disinfection supply center, which can clean multiple instruments simultaneously. The water bladder and the water spray hole rotate together to achieve all-round cleaning without dead angles and thorough decontamination. It has a high degree of automation, is easy and precise to operate, and reduces labor intensity. It can adapt to different instruments, has a stable structure and is easy to maintain, effectively improving cleaning quality and efficiency and ensuring medical safety.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
