Description

Technical Field

[0001] The invention relates to the technical field of experimental animal breeding equipment, and more particularly to a modular independent ventilation cage system cage frame which is easy to assemble and disassemble. Background Art

[0002] In the development of human life sciences, experimental animals have always been an important part of life science research. At present, the mainstream equipment for raising mice and rats in the industry is the Independent Ventilated Cage System (IVC system for short). The IVC system can effectively protect the safety of operators, animals and the environment, and is widely used in the breeding and management of experimental animals.

[0003] The traditional IVC system mainly consists of three parts: the IVC host, the cage frame and the cage box. The cage frame is equipped with a cage box air supply and exhaust duct system. In the barrier environment, the air is efficiently filtered by the IVC host and then transported to each individual cage box through the cage frame air supply duct. After the airflow circulates in the cage, the exhaust gas in the cage box passes through the cage box and the cage frame exhaust duct, and then is discharged after being efficiently filtered by the host exhaust. This one-way air flow design can ensure that the air in the cage remains clean, thereby providing a suitable breeding environment for SPF (specific pathogen-free) mice and rats. However, the existing IVC cage technology has the following major problems:

[0004] Traditional cages are bulky, especially in terms of cleaning and disinfection. Their large structure brings many difficulties to cleaning. Since the cage cannot be disassembled as a whole, the entire cage can only be operated synchronously during cleaning, which not only takes up a lot of cleaning space, but also increases the requirements for cleaning equipment and sites. For example, a dedicated walk-in cage washer or a large cleaning site is essential, but the investment cost of these equipment and sites is high and they occupy a large area, further increasing the construction and operation burden of the laboratory.

[0005] Therefore, how to provide a cage that adopts a modular design and is easy to assemble and disassemble to solve the difficulties in cleaning and disinfection is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] Therefore, the present invention provides a modular independent ventilation cage system cage frame that is easy to assemble and disassemble, which can solve the above-mentioned related problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] A modular independent ventilation cage system cage frame which is easy to assemble and disassemble, comprises a frame base, on which a plurality of shelf bodies are arranged in a matrix, the plurality of shelf bodies are plugged in horizontally, and are sequentially plugged in and arranged in the vertical direction through vertical poles; the inner side of each of the shelf bodies has an air intake channel and an exhaust channel arranged in the vertical direction, and the outer side wall thereof is fixed with an air intake nozzle and an exhaust nozzle which are respectively connected to the air intake channel and the exhaust channel; the outer side wall of each of the shelf bodies is detachably connected with a cage box bracket.

[0009] Through the above technical scheme, the present invention provides a modular independent ventilation cage system cage that is easy to assemble and disassemble. The modular assembly is realized by the horizontal and vertical plug-in of the shelf body. The modular structure allows the cage to be disassembled, which solves the problem of difficulty in cleaning and disinfecting traditional cages and reduces the requirements for cleaning equipment and sites. The matrix-arranged shelf body can adjust the number and layout of cage boxes as needed, thereby improving space utilization. The design of the air intake channel and the exhaust channel ensures that each cage box can obtain independent ventilation, providing a good living environment for experimental animals. The present invention is easy to assemble and disassemble through modular design.

The insertion design of the slot and the vertical plate makes the connection between the cage box bracket and the shelf body more stable, and improves the structural strength of the entire cage frame; the detachable connection between the cage box and the cage box bracket, and the corresponding connection between the air inlet and the air outlet and the air outlet facilitate the rapid installation and disassembly of the cage box and improve the work efficiency; at the same time, the matching accuracy between the various structures is high, and the sealing is more reliable.

The cooperation between the limiting groove and the slide bar, and the engagement of the protrusion with the slot, can ensure the accurate positioning and reliable fixation of the cage box on the carrying plate, and prevent the cage box from shifting during use. The sliding design of the slide bar makes the installation and disassembly of the cage box more convenient, and the operation can be completed by sliding the slide bar into the limiting groove and engaging the protrusion, which improves the convenience of operation.

The design of the in-place indicator rod can intuitively display whether the cage box is correctly installed in place. When the cage box is not installed, the indicator surface is exposed to prompt the operator; when the cage box is installed in place, the indicator surface is hidden, which is convenient for the operator to quickly judge the installation status. Through visual prompts, the operator's time and energy for checking the installation status of the cage box are reduced, and the assembly and use efficiency of the entire cage frame is improved.

[0013] Preferably, in the above modular independent ventilation cage system that is easy to assemble and disassemble, the side walls of two adjacent shelf bodies facing each other are provided with concave-convex plug-in parts. The design of the concave-convex plug-in parts enables the adjacent shelf bodies to be tightly connected, thereby enhancing the structural stability of the entire cage and preventing the shelf bodies from loosening or shifting during use. The cooperation of the concave-convex plug-in parts can ensure the precise alignment of the shelf bodies during assembly, thereby improving the assembly quality.

[0014] Preferably, in the above-mentioned modular independent ventilation cage system cage frame that is easy to assemble and disassemble, the interior of the shelf body has a rod-through channel, the bottom end of the vertical rod passes through the rod-through channel inside the shelf body at the bottom layer, and is fixedly connected to the frame base; the top end of the vertical rod passes through the rod-through channel inside the shelf body at the top layer, and is fixed with a top plate parallel to the frame base. The vertical rod is connected to the shelf body through the rod-through channel, and is fixed to the frame base and the top plate, forming a stable vertical support structure, ensuring the overall stability of the cage, and the design of the rod-through channel makes the installation and disassembly of the vertical rod more convenient, further improving the modularity and assembly efficiency of the cage.

[0015] Preferably, in the above-mentioned modular independent ventilation cage system that is easy to assemble and disassemble, an air intake pipe connected to the air intake channel and an exhaust pipe connected to the exhaust channel are installed on the top plate. The air intake pipe and the exhaust pipe on the top plate realize centralized ventilation management of the entire cage, which is convenient for maintenance and control of the ventilation system. The centralized layout of the air intake pipe and the exhaust pipe can ensure uniform distribution of air in the cage, further optimizing the ventilation effect of the cage box.

[0016] Preferably, in the above modular independent ventilation cage system frame that is easy to assemble and disassemble, a silicone sleeve is installed between two adjacent air inlet channels and between two adjacent air outlet channels in the vertical direction. The installation of the silicone sleeve can effectively prevent air leakage between the air inlet channel and the air outlet channel, and improve the sealing performance of the ventilation system; the silicone sleeve has a certain elasticity, and can play a role of buffering and shock absorption to a certain extent, reducing the vibration and noise generated during the air flow process.

[0017] Preferably, in the above modular independent ventilation cage system cage frame that is easy to assemble and disassemble, the bottom of the air inlet channel and the exhaust channel at the bottom layer are both installed with silicone plugs. The silicone plugs can effectively block the bottom of the air inlet channel and the exhaust channel at the bottom layer to prevent air leakage from the bottom and ensure the normal operation of the ventilation system; the silicone plugs are easy to install and replace, which is convenient for the maintenance and care of the ventilation system.

[0018] Preferably, in the above-mentioned modular independent ventilation cage system cage frame that is easy to assemble and disassemble, universal wheels are installed on the frame base, and anti-collision wheels are installed at its four corners.

The modular assembly and disassembly method simplifies the operation process, reduces the time and labor costs required for cleaning and maintenance, and improves the operating efficiency of the laboratory.

[0021] 2. The modular structure of the present invention does not require the addition of a large disinfection transfer cabin. Together with the existing cage box disinfection transfer cabin (pulsating vacuum sterilizer), each shelf body and each component can be thoroughly disinfected, thus solving the technical problem in the prior art that the cages are bulky and some old or small animal rooms are not thoroughly disinfected due to the lack of large transfer cabins.
