Description

Technical Field

[0001] This utility model relates to the field of laboratory animal transportation equipment technology, and in particular to a drinking water device for laboratory animal transportation. Background Technology

[0002] In the field of life science research and transportation of laboratory animals, ensuring their safety and health is paramount. With increasingly frequent scientific research activities, cross-regional transport of laboratory animals has become commonplace. However, meeting the basic survival needs of laboratory animals during long-distance transport, particularly the issue of water supply, has always been a key concern for researchers. Traditional methods typically rely on simple drinking equipment or substitutes to maintain the animals' fluid balance, which has played a role in ensuring their health.

[0003] Currently, the industry generally adopts several common measures to address this challenge. On the one hand, ordinary water bottles are placed inside the transport box with a fixing device for the animals to drink from; on the other hand, water is indirectly supplemented by providing foods with high water content, such as fruits or special jellies.

[0004] The aforementioned existing technologies generally suffer from problems such as water leakage and bedding contamination caused by unstable drinking equipment due to vehicle bumps, which seriously affect the quality of the living environment and survival rate of laboratory animals, and are difficult to effectively avoid the risks and hidden dangers caused by improper water supply. Therefore, a more reliable and stable solution is needed to overcome the inherent drawbacks of the current technology. Utility Model Content

[0005] This application provides a drinking device for transporting laboratory animals, which facilitates improved stability during the animal drinking process.

[0006] This application provides a drinking device for transporting laboratory animals, which adopts the following technical solution:

[0007] A drinking device for transporting laboratory animals includes a disposable sealed drinking bag and a drinking spout assembly connected thereto. The disposable sealed drinking bag is made of polyethylene and has a flexible tube extending from the middle of one side. The drinking spout assembly is connected to the disposable sealed drinking bag via the flexible tube and has two parts: a fixing section and a drinking section. The fixing section includes a first fixing part and a second fixing part. The front end of the drinking section is smooth and the rear end is provided with a convex ring with a diameter of 4 mm and a thickness of 1 mm.

[0008] By adopting the above technical solution, this utility model designs a drinking device for transporting laboratory animals. In use, the disposable sealed drinking bag is made of polyethylene, possessing good flexibility and chemical resistance, effectively preventing leakage and suitable for ethylene oxide sterilization, ensuring hygiene and safety during transportation. The drinking nozzle assembly consists of two parts: a fixing section and a drinking section. The fixing section includes a first fixing part and a second fixing part, achieving a modular design for easy disassembly and cleaning. The smooth design at the front end of the drinking section avoids potential oral damage to laboratory animals during licking, while the protruding ring at the rear end acts as a limit, preventing excessive movement of the inner tongue that could lead to structural failure or leakage. The entire device is simple and practical, effectively solving the problem of bedding contamination caused by drinking water spillage in existing technologies, while meeting the basic drinking needs of small laboratory animals during long-distance transportation, improving the safety and reliability of animal transportation.

[0009] Preferably, the top of the disposable sealed drinking bag is provided with an adhesive surface for attaching the disposable sealed drinking bag to the lower side edge of the transport box.

[0010] By adopting the above technical solution, the top of the disposable sealed water bag is provided with an adhesive surface, allowing the water bag to adhere firmly to the lower side edge of the transport box during use. This design effectively avoids the problem of the water bag shifting or tipping over due to vehicle bumps during transportation, thus ensuring that drinking water will not spill and contaminate the bedding, maintaining a dry and clean transportation environment, and further protecting the health and safety of laboratory animals.

[0011] Preferably, the first fixing part is connected to the hose, the second fixing part is connected to the drinking section, and the second fixing part and the drinking section are connected to each other in a spiral manner. A rubber pad is provided between the two parts to ensure tight connection.

[0012] By adopting the above technical solution, during use, the first fixing part is connected to the hose to ensure a stable connection between the drinking spout assembly and the disposable sealed drinking bag; the second fixing part is connected to the drinking section by a spiral, and a rubber pad is placed between the two to effectively enhance the sealing and stability of the interface and prevent liquid leakage.

[0013] Preferably, a tower-shaped spring is provided inside the first fixing part, and the bottom end of the tower-shaped spring can be locked at the junction of the first fixing part and the second fixing part.

[0014] By adopting the above technical solution, the tower-shaped spring provides a stable rebound force when the drinking section is subjected to the shaking force generated by animal licking, ensuring that the inner tongue returns to its original position, effectively controlling the outflow of water, and avoiding water waste and excessive wetting of the bedding material inside the transport box. At the same time, the locking design at the junction of the bottom of the tower-shaped spring with the first and second fixing parts enhances structural stability, preventing the spring from shifting or falling off, thereby ensuring the reliability and durability of the device throughout the entire transportation process.

[0015] Preferably, the second fixing part is provided with a groove-shaped annular rubber pad around its periphery, and a circular hole is opened on the transport box to tightly fit the transport box.

[0016] By adopting the above technical solution, the design of the annular rubber pad makes the connection between the drinking spout assembly and the transport box tighter during use, effectively preventing water leakage. Specifically, the groove-shaped annular rubber pad enhances the seal between the second fixing part and the opening of the transport box, preventing water seepage or spillage caused by vehicle bumps.

[0017] Preferably, the drinking section has a smooth stainless steel inner tongue, and a cylindrical component is provided at the rear edge of the inner tongue. This cylindrical component is tightly engaged with a convex ring provided at the rear end of the drinking section.

[0018] By adopting the above technical solution, the design of the smooth stainless steel inner tongue can effectively guide the direction of water flow during use, reducing the possibility of water leakage due to shaking; the tight combination of the cylindrical component and the convex ring further enhances the overall sealing of the device, preventing accidental leakage of liquid during transportation and ensuring the safe supply of drinking water for laboratory animals.

[0019] Preferably, the cylindrical component and the convex ring are assembled together by an interference fit, and a rubber gasket is added to the contact surface between the two to enhance the sealing performance.

[0020] By adopting the above technical solution, the cylindrical component and the convex ring are assembled together by an interference fit during use, ensuring a tight and reliable connection between the two and effectively reducing the risk of liquid leakage. At the same time, the addition of a rubber gasket at the contact surface further enhances the sealing performance, thereby better preventing moisture seepage during transportation, avoiding contamination of animal bedding, and ensuring the health and safety of laboratory animals.

[0021] Preferably, the drinking spout assembly is made entirely of stainless steel and can withstand high-pressure sterilization to achieve reuse.

[0022] By adopting the above technical solution, the overall stainless steel design of the drinking nozzle assembly ensures its high-temperature resistance, enabling it to withstand high-pressure sterilization. The choice of stainless steel further enhances the safety and reliability of the device, meeting the stringent hygiene requirements of laboratory animals.

[0023] In summary, this application has the following beneficial effects:

[0031] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0032] This utility model discloses a drinking device for transporting laboratory animals, such as... Figures 1 to 3 As shown, the device includes a disposable sealed drinking bag 1 and a drinking spout assembly 2 connected to it. The disposable sealed drinking bag 1 is made of polyethylene, possessing good flexibility and durability, and can adapt to the needs of use under various environmental conditions. A flexible tube, approximately 5 cm long, with an outer diameter of 6 mm and an inner diameter of 4 mm, is located in the middle of one side of the drinking bag. The top of the disposable sealed drinking bag 1 has an adhesive surface for attaching it to the lower side edge of the transport box. The drinking spout assembly 2 is connected to the disposable sealed drinking bag 1 via the flexible tube. The drinking spout assembly 2 is entirely made of stainless steel and can withstand high-pressure sterilization for reuse.

[0033] The drinking nozzle assembly 2 mainly consists of two parts: a fixing section 3 and a drinking section 4. The fixing section 3 is 3 cm long, and the drinking section 4 is 2 cm long. The fixing section 3 is further divided into a first fixing part 31 and a second fixing part 32. The inner diameters of the first fixing part 31 and the second fixing part 32 are different, at 4 mm and 5.5 mm respectively. The function of the first fixing part 31 is to connect with the hose on the drinking bag, so its design needs to balance sturdiness and sealing. To ensure a better sealing effect, O-rings or other types of seals can be added between these two parts. A tower-shaped spring 6 is installed inside the first fixing part 31. The tower-shaped spring 6 is 8 mm long and has a bottom diameter of about 5 mm, and it engages at the junction of the first fixing part 31 and the second fixing part 32. By applying a preload to the spring, it is ensured that it is always in a compressed state, thereby providing sufficient restoring force so that the water flow channel can be automatically closed when the mouse stops licking. The second fixing part 32 has a groove-shaped annular rubber pad 7 on its periphery, and a circular hole is opened on the transport box to tightly fit the transport box.

[0034] The front end of the drinking section 4 is smooth to prevent the mouse from scratching its tongue when licking. The rear end of the drinking section 4 protrudes inward 2 mm to form a raised ring 5 with a diameter of 4 mm and a thickness of 1 mm. Inside the drinking section 4 is a smooth stainless steel inner tongue with a length of about 2.5 mm and a diameter of 1 mm. A cylindrical component 8 with a diameter of 4 mm and a thickness of 1 mm is provided 1 mm away from the rear edge of the inner tongue. The cylindrical component 8 is assembled with the raised ring 5 by an interference fit, and a rubber gasket is added to the contact surface between the two to enhance the sealing performance. At the same time, the cylindrical component 8 can directly press against the top of the tower-shaped spring 6. After the assembly is completed, the length of the inner tongue exceeds the front end of the drinking section by 1-2 mm. When the animal licks the inner tongue and causes shaking, the liquid flows out.

[0035] Working Principle: This invention relates to a drinking device for transporting laboratory animals. By combining a disposable sealed drinking bag 1 with a drinking spout assembly 2, the structural design of the drinking spout assembly 2 achieves the effects of preventing water spillage, ensuring stable water supply, and improving the convenience of drinking for animals. The modular design of the drinking spout assembly 2 facilitates disassembly and cleaning, and its material properties allow it to withstand high-pressure sterilization, ensuring the hygiene and reusability of the device. The device exhibits good stability during transportation, effectively preventing water spillage and contamination of bedding, while meeting the drinking needs of animals during long-distance transport.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
