Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical device disinfection, and in particular to an endoscope disinfection device. Background Art
[0002] In the field of minimally invasive medical treatment, puncture needle endoscopes, with their slender needle-like structure, can precisely penetrate the human body through tiny incisions or natural cavities, enabling visual inspection and treatment of joint cavities, thoracic cavities, and other areas. Because their tip integrates precision optical components and instrument channels, disinfection and sterilization are crucial to preventing cross-infection.
[0003] Currently, there are widespread limitations in disinfection equipment for puncture needle-type endoscope tips. On the one hand, traditional cleaning methods often involve placing the endoscope tip directly on the bottom of a cleaning tank. During ultrasonic cleaning, the rigid contact between the tip and the bottom of the tank can easily loosen the precision objective lens inside, deform the instrument channel, and even scratch the anti-corrosion coating on the tip surface, affecting the service life and imaging accuracy of the equipment. On the other hand, relying solely on immersion and ultrasonic cavitation effects makes it difficult to effectively clean the inner walls of slender and deep instrument channels. This is especially true for channels longer than 10 cm, where biofilm residues are likely to form at the end, creating a blind spot for disinfection. In addition, existing equipment lacks an active internal cleaning mechanism and cannot specifically flush the instrument channel. This makes it impossible to meet the medical industry's strict requirements for thorough disinfection, increasing the potential risk of infection for patients.
[0004] Based on this, an endoscope disinfection device is proposed. Summary of the Invention

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0019] See also Figures 1-6, the present invention provides a technical solution: An endoscope disinfection device comprises a disinfection cabinet 1, a cabinet door 2 is rotatably connected to the disinfection cabinet 1, and an operating door 3 is connected to the cabinet door 2. The disinfection cabinet 1 is a closed disinfection structure, which reduces the influence of the external environment on the disinfection process. When disinfecting, it is only necessary to open the operating door 3, which improves the convenience of operation and can also prevent external impurities from entering the disinfection cabinet 1. The cabinet door 2 is opened only when the liquid in the cleaning tank 4 needs to be replaced. A connecting plate 6 is connected to the disinfection cabinet 1, and the connecting plate 6 is fixedly connected to the disinfection cabinet 1. The connecting plate 6 is parallel to the cabinet door 2 in the closed state. A cleaning tank 4 and a waste liquid tank 5 are connected to one side of the connecting plate 6. Medical disinfectant needs to be added in advance in the cleaning tank 4, and the waste liquid tank 5 needs to be regularly cleaned. The waste liquid generated during the cleaning and disinfection process will be discharged into the waste liquid tank 5. The waste liquid tank 5 is connected to a docking block 9 through a pipeline. The docking block 9 is fixedly connected to one side of the connecting plate 6. A movable rail 13 is slidably connected to one side of the connecting plate 6. An extension rail 17 is slidably connected to the movable rail 13. In the initial state, one end of the extension rail 17 faces the operating door 3. After the operating door 3 is opened, the fixed plate 12 can be pulled to move, and then the end to be disinfected is placed. The fixed plate 12 is slidably connected to the extension rail 17, and the fixed plate 12 is connected to the limit clamp 22. When placing the end, it is necessary to ensure that the end is placed on the limit clamp 22. At this time, the limit clamp 22 structure does not clamp the end, that is, the limit clamp 22 is set on the outside of the thinner part of the end. A bending groove 8 is provided on the connecting plate 6, and the bending groove 8 has an L-shaped structure. The extension rail 17 is connected to the slide bar 10 through the connecting frame 11. The slide bar 10 is slidably connected to the bending groove 8. The slide bar 10 is connected to a driving member for driving the slide bar 10 to slide on the bending groove 8. In the initial state, the slide bar 10 is set at the bending part of the bending groove 8. After the cylinder 19 is operated, it will first shrink. After ultrasonic cleaning and disinfection, the cylinder 19 is extended. After the docking pipe 32 completes the pumping of the cleaning liquid into the cleaning end, the cylinder 19 shrinks to the initial position, and the whole set of disinfection process of the single end is completed. One side of the fixing plate 12 is connected to a fixing mechanism for positioning the end of the puncture needle endoscope before sterilization.
[0020] Specifically, such as Figure 3 、 Figure 4 and Figure 5As shown, the connecting plate 6 is connected to the slide rail 7, and the slide rail 7 is slidably connected to the lifting block 14. The lifting block 14 is fixedly connected to one end of the moving rail 13, and the lifting block 14 is connected to a pressing block 15. A button block 16 is connected to one side of the connecting plate 6, wherein the lifting block 14 can only be lifted and moved in the vertical direction, and the lifting block 14 is fixedly connected to the moving rail 13, so the moving rail 13 can only be lifted and lowered. By setting the moving rail 13, the stability of the horizontal movement of the extension rail 17 is improved. The lifting block 14 is set just above the button block 16, and a control button is set on the button block 16. When the control button is pressed again, it can control the operation of the cleaning tank 4 and at the same time control the extension of the cylinder 2 28. When the cylinder 2 28 is extended to the maximum state, the cylinder 2 28 will not shrink due to the cancellation of the pressing of the control button. The shrinkage of the cylinder 2 28 is when the cylinder 1 19 is reset to the initial position, and the cylinder 2 28 begins to shrink to the initial state.
[0021] Specifically, such as Figure 5 and Figure 6 As shown, a slide bar 35 is connected to the lower end of the fixed plate 12 , and the slide bar 35 is slidably connected to the extension rail 17 . The provision of the slide bar 35 improves the stability of the fixed plate 12 sliding on the extension rail 17 .
[0022] Specifically, such as Figure 6 As shown, a handle 34 is vertically connected to the outside of the limit clamp 22, and the handle 34 is set toward the operating door 3. The handle 34 is provided to facilitate the operator to pull the fixing plate 12 closer to the operator, thereby improving the placement accuracy of the endoscope tip.
[0023] Specifically, such as Figure 4 As shown, the driving member includes a cylinder 19. After the endoscope tip to be sterilized is placed, the operator needs to start the cylinder 19. After the cylinder 19 is started, it will first shrink. When it shrinks to the maximum state, the first step of sterilizing the endoscope tip begins. After the operation is completed, the cylinder 19 begins to extend to the maximum state, and then the second step of sterilizing the tip begins. After the operation is completed, the cylinder 19 shrinks to the initial position, and one end of the cylinder 19 is rotatably connected to the slide rod 10, and the other end of the cylinder 19 is rotatably connected to one side of the connecting plate 6.
[0024] Specifically, such as Figure 4 As shown, the telescopic end of the cylinder 19 is connected to the sleeve 18, and the sleeve 18 is sleeved on the slide rod 10. The sleeve 18 is provided to improve the stability of the telescopic cylinder 19 and reduce the wear between the structures. The connecting plate 6 is connected to the rotating shaft 20, and one end of the cylinder 19 is rotatably connected to the rotating shaft 20. When the cylinder 19 is telescopic, the two ends of the cylinder 19 will rotate around the slide rod 10 and the rotating shaft 20.
[0025] Specifically, such as Figure 5 and Figure 6 As shown, the fixing mechanism includes a pressing bar 27, a bending frame 21 is connected to one side of the fixing plate 12, the bending frame 21 has an L-shaped structure, the bending frame 21 is rotatably connected to the docking frame 23 through the hinge frame 2 30, the docking frame 23 has an L-shaped structure, a connecting rod 24 is connected to the docking frame 23, the connecting rod 24 is vertically connected to the docking frame 23, a sliding sleeve 25 is slidably connected to the connecting rod 24, the upper end of the connecting rod 24 is connected to the hinge frame 3 37, the pressing bar 27 is rotatably connected to the hinge frame 3 37, a connecting bar 26 is connected between the sliding sleeve 25 and one end of the pressing bar 27, the sliding sleeve 25 is rotatably connected to the cylinder 28, and one end of the cylinder 28 is rotatably connected to the bending frame 21 through the hinge frame 1 29.
[0026] Specifically, such as Figure 5 and Figure 6 As shown, the docking frame 23 is connected to a pipe mouth 31, and the pipe mouth 31 is connected to a pipeline for conveying cleaning liquid. One end of the pipe mouth 31 is connected to a docking pipe 32, and one end of the pressing strip 27 is connected to a positioning block 33. The lower surface of the positioning block 33 is arc-shaped. This structure is pressed on the end head, which can well limit the end head and prevent the end head structure from shifting. The upper end of the sliding sleeve 25 is connected to a spring 36, and the spring 36 is sleeved on the connecting rod 24. The upper end of the spring 36 is connected to the hinged frame three 37. By setting the spring 36 structure, when the cylinder two 28 is extended, the docking frame 23 will be deflected in advance. When the docking frame 23 deflects to the docking pipe 32 abuts against one end of the end head, the pressing strip 27 will be deflected, thereby pressing the positioning block 33 on the end head.
[0027] To sum up, the endoscope disinfection equipment provided in this embodiment can open the operating door 3 when the endoscope tip needs to be disinfected, pull the fixed plate 12 outward through the handle 34, and place the end to be disinfected on the limit clamp 22, ensuring that the needle part in the end is facing the waste liquid tank 5, and then push the handle 34 until the slide bar 35 abuts against one end of the extension rail 17, and close the operating door 3.
[0028] Then start cylinder 19, cylinder 19 begins to contract, thereby driving the slide bar 10 to slide on the bending groove 8. As the slide bar 10 moves, the extension rail 17 can be driven to move synchronously. When cylinder 19 contracts to its maximum state, the slide bar 10 moves to the lower end of the bending groove 8, and the fixed plate 12 structure is synchronously immersed in the cleaning tank 4. Medical disinfectant is added to the cleaning tank 4, and the end structure can be immersed in the disinfectant together with the fixed plate 12. As the lifting block 14 moves downward, it can drive the pressing block 15 to press the button set on the button block 16, and the button can control the operation of cylinder 2 28 and the cleaning tank 4.
[0029] When the button is pressed, the cylinder 28 begins to extend, thereby first pushing the connecting rod 24 to tilt, so that the docking tube 32 connected to the docking frame 23 can dock with one end of the end to be sterilized, thereby clamping one end of the end between the docking tube 32 and the limit clamp 22. This end is similar to the non-metallic structure end of a traditional injection needle. The opening of this end is larger, which is convenient for docking with the injection needle tube. The puncture needle-type endoscope end to be sterilized here is also divided into a thicker end and a thinner end. After the thicker end is docked with the docking tube 32, the cylinder 2 is continued to The extension of 28 can push the sliding sleeve 25 to slide on the connecting rod 24, and the connecting strip 26 can push one end of the pressing strip 27 to move obliquely toward the end until the positioning block 33 is pressed on the outside of the end, thereby pressing the end on the upper surface of the fixed plate 12, ensuring the firmness of the end structure. Since the docking tube 32 and the positioning block 33 can correct and fix the position of the end, when the operator places the end, its placement position is not strictly limited. It is only necessary to ensure that the end is placed on the limit clamp 22, which greatly improves the convenience of operation.
[0030] Since the button can also control the operation of the cleaning tank 4, when the button is pressed, the cleaning tank 4 can emit ultrasonic waves to disinfect the end head and remove contaminants such as mucus and blood in the end head. Since the end head is in an overhead state at this time, the sharp end of the end head will not touch the bottom of the cleaning tank 4, avoiding friction or collision to cause damage to the precision optical components in the end head, and the pollutants cleaned will be deposited at the bottom of the tank. The overhead setting can prevent the pollutants from secondary contamination of the end head.
[0031] After the ultrasonic disinfection is completed, cylinder 19 begins to extend, thereby driving the end head away from the cleaning tank 4 and causing the sharp end of the end head to move toward the docking block 9. At this time, cylinder 2 28 maintains the maximum extension state, that is, the button only has the function of controlling cylinder 2 28 to start extending, and its contraction is not controlled by the button. When one end of the end head moves horizontally and docks with the docking block 9, cylinder 19 extends to the maximum state, and the pump body connected to one end of the pipe mouth 31 starts to operate. The pipe mouth 31 and the docking pipe 32 are interconnected, and the pipe mouth 31 is connected to the peristaltic pump through a liquid delivery pipe. The peristaltic pump can deliver the enzyme-containing cleaning solution to the docking pipe 32 and pump the cleaning solution into the end head through the docking pipe 32, thereby forming turbulent scouring, which can strip off the pollutants on the inner wall of the lumen, and the pollutants and waste liquid of the cleaned material can be delivered to the waste liquid tank 5. At this time, the disinfection operation of the end head is completed.
[0032] Then, the cylinder 19 is retracted to the initial position, and the cylinder 2 28 is retracted to cancel the limit on the end structure, and the operator can easily remove the sterilized puncture needle endoscope end.
[0033] This endoscope disinfection equipment avoids tip damage and secondary contamination through overhead clamping, and combines the internal and external collaborative mode of ultrasonic external washing and channel pumping of cleaning fluid to achieve efficient and thorough disinfection of the puncture needle-type endoscope tip, combining the advantages of automation, damage prevention and high compatibility.
