Description

Technical Field

[0001] This invention relates to the field of disinfection equipment technology, specifically to a disinfection device for animal experimental equipment. Background Technology

[0002] Animal experiments, as a crucial link in biomedical research, drug safety evaluation, and disease mechanism exploration, provide indispensable basic data and empirical support for advancements in human and animal health research by using model organisms for scientific observation and intervention under controlled conditions. During this process, researchers need to use a variety of specialized instruments, among which instruments with finger loops, such as surgical forceps, tissue forceps, and dissecting scissors, are frequently used due to their precision manipulation. These instruments come into direct contact with biological tissues and body fluids, making them highly susceptible to contamination by proteins, microorganisms, and other pollutants. Failure to thoroughly clean and disinfect them can lead to cross-infection between experimental animals, affecting the accuracy and reproducibility of experimental results, and also poses a risk of occupational exposure for operators. Therefore, effective and standardized cleaning and disinfection of these instruments is one of the core steps in ensuring experimental ethics, data reliability, and laboratory biosafety.

[0003] In current practice, the disinfection methods for laboratory instruments with finger ring structures, such as pliers, forceps, and scissors, often differ from those for glassware, plastic tubing, or cages and troughs, which have regular shapes and simple structures. Because these instruments vary in shape, have complex joints, and are not easy to place stably, conventional soaking or fixed spraying methods cannot ensure that all surfaces, especially hinges, grooves, and the inside of the finger rings, are adequately treated. The common operation method requires the operator to hold the instrument with one hand and operate the spraying equipment with the other hand to manually spray the disinfectant to cover the surface of the instrument.

[0004] However, the above-mentioned manual spraying method has the following drawbacks: First, this method can only process a single or a small number of instruments at a time, and the overall disinfection efficiency needs to be improved. Second, in order to ensure that the disinfectant can fully wet the complex structural surfaces and hidden crevices of the instruments, the operator needs to repeatedly adjust the instrument posture and spray angle during the process. This process will bring significant physical burden if it is carried out continuously. In addition, when manually spraying at close range, it is difficult for the operator to completely avoid contact with disinfectant droplets or aerosols, which may have a potential impact on the operator's health. Therefore, this invention proposes a disinfection device for animal experimental instruments to solve the above problems. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 6This invention provides a technical solution: a sterilization device for animal experimental equipment, comprising: a sterilization box 1, which serves as the main body of the device and supports various components; a sterilization rack 2 rotatably mounted at the center of the sterilization box 1; the sterilization rack 2 being capable of rotation; and several clamping mechanisms positioned along the edges of the sterilization rack 2. Each clamping mechanism includes a set of relatively rotatable clamping blocks 3 and a first driving component for driving the two clamping blocks 3 to move relative to each other. The upper side of the sterilization rack 2 is connected to a second driving component, which drives the sterilization rack 2 to rotate along its axis, thereby causing the sterilization rack 2 to drive the clamping mechanisms to rotate synchronously. The sterilization box 1 has clamping mechanisms on both sides that can rotate along the edges of the sterilization rack 2. A connecting frame 4 reciprocates along the width of the disinfection box 1. Each connecting frame 4 has a spray pipe frame 5 fixedly fitted at one end. Several spray heads are fixedly connected to the output end of the spray pipe frame 5. The input end of the spray pipe frame 5 is connected to the output end of the telescopic hose 6. The input end of the telescopic hose 6 is connected to the output pipe of the pump body installed on the disinfection box. The input pipe of the pump body is connected to the disinfection box. The disinfection box is fixedly installed on both sides of the disinfection box 1 and is used to hold disinfectant. A transmission component is connected to the other end of the connecting frame 4. The transmission component is used to drive the connecting frame 4 to reciprocate along the width of the disinfection box 1. A second drive component is connected to the transmission component, and the second drive component can drive the transmission component to move.

[0021] In use, experimental instruments with finger ring structures, such as pliers, tweezers, and scissors, are placed on the edge of the sterilization rack 2 inside the sterilization chamber 1, with the finger rings positioned between the two clamping blocks 3. Driven by the first drive component, the two clamping blocks 3 rotate until their bottom ends abut, thus hooking the instruments between them. This process is repeated to hook several instruments in sequence. Then, the second drive component operates synchronously, driving the transmission component, which in turn causes the sterilization rack 2 to rotate. The sterilization rack 2 then causes several instruments to move in a circular motion. Simultaneously, the transmission component drives the spray tube frame 5 to reciprocate along the width of the sterilization chamber 1, thereby causing the spray head to move synchronously. With the telescopic hose 6, pump body, and sterilization box connected, disinfectant is sprayed from the spray head to sterilize the instruments. The reciprocating motion of the spray head, combined with the circular motion of the instruments, allows the disinfectant to spray the instruments from different directions, avoiding the inconvenience of manual operation, improving sterilization efficiency and effect, and also avoiding the risk of operators coming into contact with the disinfectant, thus improving safety.

[0022] A transparent door 7 is hinged to the front of the disinfection box 1. A filter plate 8 is installed below the transparent door 7. The filter plate 8 is inserted into the disinfection box 1 and is detachably connected to the disinfection box 1 by bolts. A collection box 9 is installed below the filter plate 8 and is slidably installed at the bottom of the disinfection box 1. One side of the transparent door 7 is hinged to the disinfection box 1, and the other side of the transparent door 7 is locked to the disinfection box 1 by a buckle, so as to facilitate quick opening or closing of the transparent door 7. In addition, the transparent door 7 also makes it easy to see the inside of the disinfection box 1 to observe the disinfection status. During the disinfection process, impurities adhering to the instruments are sprayed off and flow with the disinfection solution to the filter plate 8. The filter plate 8 filters the impurities, and the filtered disinfection solution flows into the collection box 9, which facilitates subsequent processing and recycling of the disinfection solution. The filter plate 8 can be disassembled for cleaning to avoid contaminating the internal environment of the disinfection box 1. The collection box 9 can be pulled out from the bottom of the disinfection box 1 to facilitate centralized cleaning of the collected disinfection solution.

[0023] Several U-shaped frames 10 are fixedly connected to the edge of the disinfection rack 2. The disinfection rack 2 is radially shaped. The first drive component includes a pull rod 11, a connecting block 12 fixedly connected to one end of the pull rod 11, and a connecting rod 13 slidably connected to the connecting block 12. The pull rod 11 is slidably sleeved in the U-shaped frame 10. The U-shaped frame 10 guides and limits the pull rod 11. An arc-shaped hole 14 is opened on the surface of the connecting block 12. A return spring 15 is fixedly connected between the upper surface of the connecting block 12 and the U-shaped frame 10. The bottom end of the connecting rod 13 is fixedly connected to the clamping block 3. One side of the top end of the connecting rod 13 is rotatably connected to the U-shaped frame 10 through a fixing pin. The other side of the top end of the connecting rod 13 is slidably connected to the arc-shaped hole 14 on the surface of the connecting block 12 through a sliding pin.

[0024] In the initial state, the bottom ends of the two clamping blocks 3 are abutting each other and in a closed state. When it is necessary to clamp and scrape the instrument, by pulling the pull rod 11 upward, the pull rod 11 drives the connecting block 12 to move synchronously. The connecting block 12 then squeezes the return spring 15. At the same time, the connecting block 12 pushes the connecting rod 13 away from the pull rod 11 through the arc-shaped hole 14 and the cooperation of the sliding pin. Then, the two connecting rods 13 move in opposite directions. The connecting rod 13 rotates under the limit of the fixed pin until the two clamping blocks 3 separate. Then, the finger ring of the instrument can be placed between the two clamping blocks 3. Release the pull rod 11, and under the reverse elastic force of the return spring 15, the clamping blocks 3 can be reset and the bottom ends abutting each other. This limits the hanging of the instrument and finally realizes the hanging of several instruments, realizing the one-time disinfection and cleaning of several instruments, improving the disinfection efficiency.

[0025] The second drive assembly includes a geared motor 16 fixedly mounted on the upper surface of the disinfection box 1, the geared motor 16 being electrically connected to an external control device, a drive shaft 17 fixedly connected to the output end of the geared motor 16, a drive gear 18 fixedly connected to the drive shaft 17, a transmission gear 19 meshing with the drive gear 18, a driven gear 20 meshing with the transmission gear 19, and a driven shaft 21 fixedly connected to the driven gear 20. The top end of the drive shaft 17 passes through the disinfection box 1 and is fixedly connected to the output end of the geared motor 16, the bottom end of the drive shaft 17 is fixedly connected to the drive gear 18, the upper side of the transmission gear 19 meshes with the drive gear 18 for transmission, the lower side of the transmission gear 19 meshes with the driven gear 20 for transmission, the top end of the driven shaft 21 is fixedly connected to the driven gear 20, and the bottom end of the driven shaft 21 is fixedly connected to the upper surface of the disinfection rack 2. Both the drive shaft 17 and the driven shaft 21 are rotatably mounted on a support frame fixedly connected to two partitions 22, and the support frame supports and limits the drive shaft 17 and the driven shaft 21.

[0026] When disinfection begins, the reduction motor 16 is started to drive the drive shaft 17 to rotate slowly. The drive shaft 17 then drives the drive gear 18 to move synchronously. The drive gear 18 drives the driven gear 20 to rotate through the meshing of the transmission gear 19. Under the rotation of the driven gear 20, the driven shaft 21 drives the disinfection rack 2 fixedly connected to its bottom end to rotate slowly, thereby driving several instruments to move in a circular motion. This facilitates the adjustment of the angle of the instruments and makes it easier to spray disinfectant on different parts of the instruments, thus improving the disinfection effect and quality.

[0027] The disinfection box 1 has two partitions 22 symmetrically arranged inside. The partitions 22 are fixedly connected to the inner wall of the disinfection box 1. The bottom of the partitions 22 has a guide groove 23. The connecting frame 4 is slidably installed in the guide groove 23. The transmission assembly includes a transmission shaft 24 fixedly sleeved in the transmission gear 19, a rotating plate 25 fixedly connected to the end of the transmission shaft 24, a turntable 26 slidably connected to the rotating plate 25, a swing rod 27 slidably connected to the turntable 26, and a transmission frame 28 slidably connected to the swing rod 27. The transmission shaft 24 passes through the partitions 22 and is rotatably connected to the partitions 22. The two ends of the transmission shaft 24 are supported and limited by the partitions 22. The turntable 26 is rotatably engaged in the limiting frame 29. The limiting frame 29 engages and limits the turntable 26. The limiting frame 29 is fixedly connected to the top wall of the disinfection box 1. The surface of the turntable 26 has a short sliding groove 30, and the surface of the swing rod 27 has a long sliding groove 31. The upper side of the transmission frame 28 A limiting groove 37 is provided. The bottom of the transmission frame 28 is slidably sleeved on the guide frame 38. The guide frame 38 is fixedly connected to the inner wall of the disinfection box 1. The guide frame 38 guides and limits the transmission frame 28. The transmission frame 28 is fixedly connected to the end of the connecting frame 4 away from the spray pipe frame 5. One end of the rotating plate 25 is fixedly connected to the transmission shaft 24. The other end of the rotating plate 25 is rotatably connected to the first slider 32 through a short locking pin 34. The first slider 32 is slidably installed in the short slide groove 30. The side of the turntable 26 away from the transmission shaft 24 is fixedly connected to one end of the long locking pin 35. The other end of the long locking pin 35 is rotatably connected to the second slider 36. The second slider 36 is slidably installed in the long slide groove 31. One end of the swing rod 27 is rotatably connected to the fixed block fixedly connected to the top wall of the disinfection box 1 through a fixing pin. The other end of the swing rod 27 is rotatably connected to the limiting block 33 through a limiting pin. The limiting block 33 is slidably installed in the limiting groove 37.

[0028] While the appliance is in circular motion, the transmission gear 19 drives the transmission shaft 24 to rotate. The transmission shaft 24 then drives one end of the rotating plate 25, which is fixedly connected to both ends, to rotate. The other end of the rotating plate 25, limited by the short locking pin 34, drives the first slider 32 to slide back and forth in the short slide groove 30, thereby driving the turntable 26 to move in a circular motion within the limiting frame 29. The turntable 26, connected by the long locking pin 35, drives the second slider 36 to slide back and forth along the inside of the long slide groove 31, thereby driving one end of the swing rod 27 to swing back and forth about the fixed pin on the fixed block as the axis, thus causing the swing rod to swing back and forth. The other end of the rod 27, under the rotational engagement between the limiting pin and the limiting block 33, causes the limiting block 33 to slide up and down in the limiting groove 37, thereby pushing the transmission frame 28 to move. The transmission frame 28 is then limited on the guide frame 38, so that the transmission frame 28 moves back and forth along the length direction of the guide frame 38. The transmission frame 28 drives the connecting frame 4 to move synchronously, so that the connecting frame 4 drives the spray pipe frame 5 to move back and forth synchronously. This achieves multi-directional spraying of the instrument, avoids the trouble of manual operation, and ensures that the disinfectant can fully wet the complex structural surfaces and hidden gaps of the instrument.
