Abstract
Description
Technical Field
[0001] This utility model belongs to the field of disinfection machine technology, specifically a medical device cleaning and disinfection machine. Background Technology
[0002] A disinfection machine is a device that uses physical, chemical, or combined methods to kill or remove pathogenic microorganisms in the air, on object surfaces, and in water. It effectively reduces the risk of infection through methods such as ultraviolet irradiation, ozone release, high-temperature steam, plasma technology, or chemical spraying.
[0003] Medical devices need to be cleaned and disinfected after use. Disinfection machines are used to disinfect medical devices to ensure their hygiene. Existing disinfection machines generally place the medical devices to be disinfected inside the machine and disinfect them by spraying disinfectant. Although this method can disinfect, the fixed position of the medical devices prevents the disinfectant from disinfecting the devices thoroughly, thus greatly reducing the disinfection effect. Therefore, this method needs to be improved. Utility Model Content
[0004] The purpose of this invention is to address the above problems by providing a medical device cleaning and disinfection machine that offers more comprehensive disinfection.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a medical device cleaning and disinfection machine, comprising a housing, a hinged movable door on the front of the housing, a limiting plate fixedly installed on the rear side of the bottom of the inner surface of the housing, a cover plate fixedly connected to the top of the limiting plate, a toothed plate fixedly installed on the rear side of the bottom of the housing, a drive motor fixedly installed on the right side between the limiting plate and the toothed plate, a threaded rod fixedly connected to the other end of the output shaft of the drive motor, a movable plate threadedly sleeved on the middle of the outer surface of the threaded rod, the outer surface of the movable plate being movably connected to the outer surfaces of the limiting plate and the toothed plate respectively, a round shaft movably sleeved inside the top of the movable plate, a gear fixedly sleeved on the rear end of the outer surface of the round shaft, the outer surface of the gear meshing with the top of the toothed plate, a limiting block movably sleeved on the front side of the outer surface of the round shaft, the inner surface of the limiting block movably sleeved with the inner surface of the limiting plate, and a mesh plate fixedly connected to the front end of the round shaft.
[0006] As a preferred embodiment of this utility model, side plates are movably sleeved inside the left and right sides of the perforated plate, and a movable perforated plate is fixedly connected to the top of the side plates. A handle is fixedly connected to the front side of the top of the movable perforated plate.
[0007] As a preferred embodiment of this utility model, a base plate is fixedly connected to the bottom of the side plate, and a first spring is fixedly connected to the top of the base plate. The top of the first spring is fixedly connected to the bottom of the plate on which the mesh plate is placed.
[0008] As a preferred embodiment of this utility model, fixing blocks are fixedly installed on both the left and right sides of the front top of the perforated plate, and a rotating plate is hinged to the front top of the perforated plate, with the side of the rotating plate being movably connected to the outer surface of the fixing blocks.
[0009] As a preferred embodiment of this utility model, an installation box is fixedly installed on the front of the fixing block, a plug rod is movably sleeved inside the installation box, the inner end of the plug rod extends to the outside of the installation box and is movably sleeved with a fixing frame, and the outer surface of the fixing frame is fixedly connected to the front of the rotating plate.
[0010] As a preferred embodiment of this utility model, a second spring is fixedly connected to the outer side of the insertion rod, the other end of the second spring is fixedly connected to the inner surface of the mounting box, and a pull plate is fixedly connected to the front side of the insertion rod.
[0011] As a preferred embodiment of this utility model, a fixing pipe is fixedly sleeved on the top of the box, a nozzle is fixedly connected to the bottom of the fixing pipe, and a drain pipe is fixedly sleeved inside the bottom of the box.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up a toothed plate, a movable plate, gears, and a perforated plate, allows the operator to place the medical device to be disinfected on top of the perforated plate. Then, by starting the drive motor, the threaded rod drives the movable plate to move. The movable plate will drive the circular shaft to move under the limiting action of the limiting block, thereby causing the gear to rotate along the top of the toothed plate. This, in turn, drives the perforated plate to rotate through the circular shaft, thereby causing the medical device to rotate, so that the medical device can achieve a more comprehensive disinfection effect.
[0014] 2. This utility model, by setting up a side plate, a movable mesh plate and a first spring, allows the operator to pull the handle upwards, causing the movable mesh plate to rise. Then, after opening the rotating plate and placing the medical device on top of the mesh plate, the elastic force of the first spring will push the bottom plate downwards. This, in turn, causes the movable mesh plate to move downwards through the side plate. The movable mesh plate and the mesh plate work together to clamp and fix the medical device, preventing it from colliding and being damaged when the medical device rotates.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1 to 9As shown, this utility model provides a medical device cleaning and disinfection machine, including a box body 1. A movable door 2 is hinged to the front of the box body 1. A limiting plate 3 is fixedly installed on the rear side of the bottom of the inner surface of the box body 1. A cover plate 4 is fixedly connected to the top of the limiting plate 3. A toothed plate 5 is fixedly installed on the rear side of the bottom of the box body 1. A drive motor 6 is fixedly installed on the right side between the limiting plate 3 and the toothed plate 5. A threaded rod 7 is fixedly connected to the other end of the output shaft of the drive motor 6. A movable plate 8 is threadedly sleeved on the middle of the outer surface of the threaded rod 7. The outer surface of the movable plate 8 is movably connected to the outer surfaces of the limiting plate 3 and the toothed plate 5 respectively. A round shaft 9 is movably sleeved inside the top of the movable plate 8. A gear 10 is fixedly sleeved on the rear end of the outer surface of the round shaft 9. The outer surface of the gear 10 meshes with the top of the toothed plate 5. A limiting block 11 is movably sleeved on the front side of the outer surface of the round shaft 9. The inner surface of the limiting block 11 is movably sleeved with the inner surface of the limiting plate 3. A mesh plate 12 is fixedly connected to the front end of the round shaft 9.
[0027] The operator places the medical device to be disinfected on top of the perforated plate 12. When disinfecting the medical device, the operator starts the drive motor 6, which causes the threaded rod 7 to move the moving plate 8. The moving plate 8 then moves the round shaft 9 under the limiting action of the limiting block 11, causing the gear 10 to rotate along the outer surface of the toothed plate 5, thereby causing the round shaft 9 to rotate. This allows the round shaft 9 to drive the perforated plate 12 to rotate, thus enabling more comprehensive disinfection of both the front and back of the medical device.
[0028] The perforated plate 12 has side plates 13 that are movably sleeved inside both sides. The top of the side plates 13 is fixedly connected to a movable perforated plate 14, and a handle 15 is fixedly connected to the front of the top of the movable perforated plate 14.
[0029] By setting up a movable perforated plate 14, the movable perforated plate 14 and the placement perforated plate 12 can cooperate to clamp and fix the medical device placed on top of the placement perforated plate 12, thereby preventing the medical devices from colliding with each other when the placement perforated plate 12 rotates.
[0030] The bottom of the side plate 13 is fixedly connected to the bottom plate 16, and the top of the bottom plate 16 is fixedly connected to the first spring 17. The top of the first spring 17 is fixedly connected to the bottom of the perforated plate 12.
[0031] By setting a first spring 17, the first spring 17 can push the perforated plate 12 downward under the elastic recovery action, thereby driving the movable perforated plate 14 downward through the side plate 13.
[0032] Fixing blocks 18 are fixedly installed on both the left and right sides of the top front side of the perforated plate 12, and a rotating plate 19 is hinged to the top front side of the perforated plate 12. The side of the rotating plate 19 is movably connected to the outer surface of the fixing block 18.
[0033] The operator can now rotate and open the rotating plate 19 to place the medical device that needs to be sterilized on top of the perforated plate 12.
[0034] The mounting box 20 is fixedly installed on the front of the fixing block 18. The mounting box 20 is movably connected to the inside of the mounting box 20. The inner end of the mounting box 21 extends to the outside of the mounting box 20 and is movably connected to the fixing frame 22. The outer surface of the fixing frame 22 is fixedly connected to the front of the rotating plate 19.
[0035] When the insert rod 21 is inserted into the inside of the fixed frame 22, it will fix the rotating plate 19.
[0036] The insertion rod 21 is fixedly connected to a second spring 24 on its outer side, and the other end of the second spring 24 is fixedly connected to the inner surface of the mounting box 20. The insertion rod 21 is fixedly connected to a pull plate 23 on its front side.
[0037] The operator can push the pull plate 23 outward to move the insertion rod 21 into the mounting box 20, thereby causing the insertion rod 21 to disengage from the inside of the fixing frame 22.
[0038] The top of the housing 1 is fixedly fitted with a fixing pipe 25, the bottom of the fixing pipe 25 is fixedly connected with a nozzle 26, and the bottom of the housing 1 is fixedly fitted with a drain pipe 27.
[0039] Operators can use a water pump to deliver disinfectant into the fixed pipe 25, and then spray it out from the nozzle 26. The disinfectant collected inside the box 1 will be discharged through the drain pipe 27.
[0040] Working principle and usage process of this utility model:
[0041] The operator opens the movable door 2 and pushes the two pull plates 23 to move in opposite directions. This causes the pull plates 23 to move the insertion rod 21 into the mounting box 20, disengaging the insertion rod 21 from the fixed frame 22 and releasing the fixing effect on the fixed frame 22 and the rotating plate 19. Then, the operator rotates the rotating plate 19 to open it and pulls the handle 15 upward to place the medical device to be sterilized on top of the placement mesh plate 12. The operator then releases the handle 15, and due to the elastic force of the first spring 17, the bottom plate 16 is pushed downward. This causes the movable mesh plate 14 to move downward through the side plate 13, allowing the movable mesh plate 14 to cooperate with the placement mesh plate 12 to clamp and fix the medical device, preventing it from colliding and being damaged when the medical device rotates. The operator then rotates the rotating plate 19 to close it, allowing the insertion rod 21 to be inserted into the fixed frame 22, thus fixing the rotating plate 19.
[0042] Then, the operator uses a water pump to deliver disinfectant into the fixed tube 25, so that the disinfectant is sprayed out through the nozzle 26 to disinfect the medical device. At this time, by starting the drive motor 6, the threaded rod 7 drives the moving plate 8 to move. The moving plate 8 will drive the round shaft 9 to move under the limiting action of the limiting block 11, so that the gear 10 rotates along the outer surface of the toothed plate 5, thereby driving the round shaft 9 to rotate. The round shaft 9 can drive the mesh plate 12 to rotate, so that the medical device can rotate, thereby enabling a more comprehensive disinfection treatment of the front and back of the medical device.
