Description

Technical Field

[0001] This utility model relates to the field of animal experimental technology, and more specifically, to a device for euthanizing experimental animals. Background Technology

[0002] In modern life sciences, medicine, and other scientific research fields, rodents are widely used experimental subjects due to their physiological similarities to humans, short reproductive cycles, and relatively low cost. However, after the experiment, to avoid potential impacts on the experimental environment, such as the spread of diseases or interference with subsequent experiments, the animals need to be manually removed and euthanized. During the removal process, there is a risk of the animal biting or escaping; if it escapes, the pathogens it carries may be infectious, posing a safety hazard. Therefore, we propose a device for euthanizing experimental animals. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a device for euthanizing laboratory animals to solve the technical problem of safety hazards in the current euthanasia process.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a laboratory animal euthanasia device, including a processing box, a processing port installed on one side of the processing box, a connecting cylinder connected to the outside of the processing port, a valve at the end of the connecting cylinder, a spiral tube connected to the end of the connecting cylinder, a flexible metal tube connected to the end of the spiral tube and communicating with an external animal experimental area, a plurality of conical hole structures inside the spiral tube, and a driving structure on the outside of the spiral tube.

[0005] Preferably, the diameter of the spiral tube gradually decreases from the inlet end to the outlet end of the connecting cylinder, and the constriction of the spiral tube forms an opening to lure rodents into it.

[0006] Preferably, the cone-shaped structure includes multiple elastic metals, which are in the shape of arc fan. An elastic cotton layer is connected between adjacent sides of the multiple elastic metals, and the multiple elastic cotton layers and elastic metals surround a hole. A limiting member is installed at the end of the elastic metal at the cone tip.

[0007] Preferably, the limiting component includes a central shaft, a one-way bearing is mounted on the outer periphery of the central shaft, a circular sleeve is fixed to the outer ring of the one-way bearing, and multiple limiting blades are connected to the outer periphery of the circular sleeve, with the multiple limiting blades arranged in a circular array around the circular sleeve.

[0008] Preferably, the driving structure includes a spiral groove, which is formed on the inner wall of the spiral tube. The spiral groove has a spiral trajectory and is designed to be concave outward. An air-blocking strip for isolating adjacent spiral grooves is integrally formed on the edge of the spiral groove trajectory.

[0009] Preferably, a spiral air inlet is provided on one side of the spiral groove, and the trajectory of the spiral air inlet is adapted to the spiral groove so that the gas moves along the spiral groove to form a driving track.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a passage composed of a treatment box, a connecting cylinder, a spiral tube, and a metal flexible tube to directly connect the device to the external animal experimental area where the rodents are located. This eliminates the need for manual handling of the rodents, avoiding the risk of animal bites. After the rodents enter, they can be humanely euthanized by injecting medication or sucking out internal air through the treatment port. This effectively prevents rodents from escaping and contaminating the experimental environment, ensuring the safety of the experimental environment, reducing the risk of potential disease transmission, and solving the safety hazards that exist in the euthanasia process.

[0011] 2. This utility model also features a cleverly designed spiral tube with a diameter that gradually decreases from the inlet end to the outlet end of the connecting cylinder. Combined with multiple internal conical hole structures, the conical openings formed by elastic metal and elastic cotton layers attract rodents to enter. At the same time, the combination of a one-way bearing and a limiting blade in the limiting component allows the limiting blade to rotate freely when the rodent enters, but it is limited when the rodent tries to crawl back. The multiple conical hole structures gradually guide the rodent to the treatment box, ensuring that the rodent cannot escape and guaranteeing the smooth execution of the euthanasia operation.

[0012] 3. This utility model also features a spiral groove on the inner wall of the spiral tube, which, together with an air-blocking strip, prevents gas from crossing. The spiral air inlet guides the gas input from the external air source to move along the spiral groove trajectory, forming a driving track. By using the gas to drive away the rodents, it can effectively solve the problem of rodents being unwilling to enter the device, allowing the rodents to be guided to the treatment box more smoothly and improving the efficiency of the entire culling process.

[0015] like Figures 1 to 5 As shown, this utility model relates to a laboratory animal euthanasia device, including a treatment box 1. The treatment box 1 is made of high-strength, corrosion-resistant, and well-sealed materials, such as high-quality stainless steel or special engineering plastics, to ensure no leakage occurs during the euthanasia process and to guarantee the safety of the experimental environment. A treatment port 2 is installed on one side of the treatment box 1. The treatment port 2 is a key part for the humane euthanasia of rodents. The treatment port 2 is equipped with a high-precision injection interface and an air suction interface, which can accurately control the injection volume of the drug or the air suction volume to achieve painless euthanasia of the rodents. A connecting tube 3 is connected to the outside of the treatment port 2. The connecting tube 3 is also made of a sturdy and durable material, and its end is equipped with a valve. This valve has good sealing and reliability, and can effectively control the opening and closing of the passage when needed to prevent gas leakage or rodent escape. A spiral tube 4 is connected to the end of the connecting tube 3. Tube 4 is an important channel for guiding rodents into treatment box 1. The diameter of the spiral tube 4 gradually decreases from the inlet end to the outlet end of the connecting tube 3. This design simulates the shape of burrows in the natural environment of rodents, which has a natural attraction to them. The spiral tube 4 is made of a metal material with certain flexibility and strength, such as aluminum alloy, which can ensure the stability of the structure and adapt to different experimental environment layouts to a certain extent. A metal hose 5 is installed at the end of the spiral tube 4 to connect with the external animal experimental area. The metal hose 5 has good flexibility, which allows the operator to flexibly adjust its position according to the actual situation. A valve is also installed at the end of the metal hose 5 to further ensure the controllability of the passage. The operator can use a longer metal hose 5 to manually move it to the side of the rodents as needed, and use the rodents' burrowing instinct to guide them into the device. The operation is simple and convenient.

[0016] rodent guidance structure Conical Structure: To more effectively guide rodents into the treatment chamber 1, the spiral tube 4 contains multiple conical structures 6. Each conical structure 6 includes multiple elastic metals 601. These elastic metals 601 are made of a metal material with good elasticity and corrosion resistance, such as stainless steel alloy, and are formed in an arc-shaped fan. Elastic cotton layers 602 connect adjacent sides of the multiple elastic metals 601. The elastic cotton layers 602 are made of soft, non-toxic, and non-irritating cotton material to rodents, and after special treatment, possess a certain degree of elasticity and toughness. The multiple elastic cotton layers 602 and elastic metals 601 surround a cone-shaped opening. This cone-shaped structure effectively simulates the entrance to a rodent's natural burrow, strongly attracting rodents. A restraining element 63 is installed at the tip of each elastic metal 601. The restraining element 63 includes... The central shaft 631 is made of high-strength metal to ensure that it will not deform during long-term use. A one-way bearing 632 is installed on the outer periphery of the central shaft 631. The one-way bearing 632 has high precision and good rotation performance. A circular sleeve 633 is fixed on its outer ring. Multiple limiting blades 634 are connected to the outer periphery of the circular sleeve 633. The limiting blades 634 are made of lightweight and strong materials, such as plastic alloy, to seal the opening. When a rodent enters, under its own thrust, the limiting blades 634 will rotate freely with the one-way bearing 632, allowing the rodent to pass smoothly. When the rodent tries to crawl back, the limiting blades 634 will be limited by the one-way bearing 632 and cannot rotate in the opposite direction, thus effectively preventing the rodent from crawling back. The multiple conical hole structures 6 work together to gradually guide the rodent to the treatment box 1.

[0017] Repelling Structure: To further improve the efficiency of rodent entry into the device, a repelling structure 7 is provided on the outer side of the spiral tube 4. The repelling structure 7 includes a spiral groove 701, which is formed on the inner wall of the spiral tube 4 using high-precision machining technology to create a spiral trajectory. The spiral groove 701 is designed to be concave outward, which can effectively guide the air flow and generate a repelling force for rodents. An air-blocking strip 702 is integrally formed on the edge of the spiral groove 701 trajectory. The air-blocking strip 702 is made of rubber material with good sealing performance and is used to isolate adjacent spiral grooves 701. The spiral path on the trajectory prevents gas cross-contamination and ensures that the gas flows along the predetermined trajectory. A spiral air inlet 703 is provided on one side of the spiral groove 701. The trajectory of the spiral air inlet 703 is precisely matched with the spiral groove 701, which can accurately guide the gas input from the external air source into the spiral groove 701. The gas moves along the spiral groove 701 to form a driving track. By connecting to the external air source, the gas is blown towards the spiral groove 701 under the guidance of the spiral air inlet 703 and moves along its trajectory, which drives the rodents and makes them move towards the treatment box 1 more quickly.
