Description

Technical Field

[0001] This utility model relates to the field of mouse breeding technology, and more specifically, to a soft-pack isolator for mouse breeding that is easy to assemble and disassemble. Background Technology

[0002] In the field of biomedical experiments, mouse isolators are crucial devices for maintaining the specific pathogen-free state of laboratory animals and ensuring the accuracy and reliability of experimental data. These devices effectively isolate mice from microbial contamination in the external environment, providing a stable and clean breeding environment. They are indispensable experimental support tools in fields such as infectious disease research, drug development, and genetic engineering.

[0003] Existing publication number CN218451268U discloses a large soft-pack isolator suitable for raising albino mice, comprising a stainless steel support frame and a soft pack. The soft pack is fixedly mounted on the stainless steel support frame and is equipped with a docking mechanism for transfer. A ventilation mechanism is provided on the side wall of the soft pack. The docking mechanism includes a circular pipe, the end of which is threaded onto the soft pack. Inside the isolator, the working lighting intensity is too strong for albino mice. The presence of the soft pack on this isolator effectively reduces the transmittance of ambient light, thereby maintaining a suitable light intensity for animal rearing within the isolator. When not in use, the light intensity is lower. The presence of the soft pack on this isolator ensures high light transmittance even under low ambient light intensity, generally maintaining the light intensity requirements for animal rearing. The inventors discovered the following problems with the existing technology during the development of this utility model: While existing soft pack isolators have the advantage of being lightweight, they generally have drawbacks such as complicated disassembly and assembly steps and easy degradation of sealing performance at the connection after repeated disassembly and assembly, which reduces the efficiency of experimental operations and makes it difficult to adapt to the rapid deployment needs in different scenarios. Therefore, a soft-pack isolator for mouse rearing that is easy to disassemble and assemble is proposed to address the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mouse feeding soft pack isolator that is easy to disassemble and assemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mouse rearing soft-pack isolator that is easy to assemble and disassemble, comprising a horizontal support, a vertical support, and a soft packing film. Quick-connect components are provided at both ends of the horizontal support. The horizontal support is slidably connected to the vertical support via the quick-connect components, and multiple horizontal and vertical supports are combined to form a fixed frame. A soft packing film with an antibacterial and anti-corrosion coating sprayed on its inner wall and a transparent observation window is installed on the top of the horizontal support. An air outlet pipe and an air inlet pipe are fixedly connected to one side of the soft packing film, and a sealing gasket is adhered to the connection between the soft packing film and the air outlet pipe and the air inlet pipe. The end of the air inlet pipe is connected to an oxygen supply unit. An installation component for lifting the soft packing film is provided in the middle of the quick-connect components.

[0006] By adopting the above technical solution, the horizontal and vertical supports are slidably spliced ​​together to form a variable frame through quick-connect components. The soft film fits the frame, and the air outlet and inlet pipes are equipped with sealing gaskets to achieve air path sealing. The quick-connect components are equipped with installation components to assist in hoisting. They do not require tools for disassembly and assembly, the air path is sealed to prevent leakage, and the installation components simplify the positioning of the soft film. They can be quickly adapted to different experimental scenarios and greatly improve the efficiency of equipment turnover and layout.

[0007] Preferably, the quick-connect assembly includes T-shaped locking blocks fixed to both ends of the horizontal support; the vertical support has sliding grooves at both ends that are adapted to the T-shaped locking blocks, and the sliding grooves can slide back and forth in the middle of the T-shaped locking blocks; the top of the T-shaped locking blocks is provided with a limiting mechanism for limiting the sliding grooves.

[0008] By adopting the above technical solution, the T-shaped blocks at both ends of the horizontal support slide into the groove of the vertical support to adjust the frame size. The top limiting mechanism of the T-shaped blocks locks the connection, which can be adapted to various specifications of soft film. No fasteners are required for disassembly and assembly, which not only improves the efficiency of frame assembly, but also ensures the stability of frames of different sizes, and adapts to diverse experimental space requirements.

[0009] Preferably, the limiting mechanism includes a threaded hole on the top of the T-shaped block; a limiting rod is threadedly connected to the middle of the threaded hole, and the top of the limiting rod is a circular protrusion, which can restrict the vertical bracket to one side after the vertical bracket is installed.

[0010] By adopting the above technical solution, a limiting rod is built into the threaded hole at the top of the T-shaped card block. Rotating the limiting rod causes its protrusion to press against the vertical bracket. The protrusion increases the locking contact area, making the connection more stable. There is no wear on the parts during disassembly and assembly, and the stable locking effect can still be maintained after long-term use, reducing equipment maintenance losses.

[0011] Preferably, the mounting assembly includes multiple sliders; the sliders can slide back and forth in the middle of the transverse support; a hook is fixedly connected to the bottom of the slider; a fixing plate is fixedly connected to the top of the soft film; multiple lifting holes are opened on the surface of the fixing plate, and the end of the hook can pass through the middle of the lifting hole to lift the soft film.

[0012] By adopting the above technical solution, the slider on the horizontal support can be slidably adjusted, and its bottom hook can be inserted into the lifting hole of the top fixing plate of the soft film to complete the hoisting. It can adapt to different hoisting points of the soft film, making the soft film installation more flat. No additional fasteners are required, and a single person can quickly complete the installation and removal of the soft film, greatly simplifying the installation steps.

[0013] Preferably, a mounting shell is fixedly connected to the end of the air outlet pipe; an exhaust fan with a speed control switch is installed in the middle of the mounting shell to accelerate the airflow in the middle of the soft packaging film.

[0014] By adopting the above technical solution, the exhaust fan built into the end housing of the exhaust pipe accelerates the gas circulation inside the soft membrane to ensure environmental stability. The modular design makes the exhaust fan maintenance more convenient, eliminating the need to disassemble the gas circuit, which saves maintenance time and does not affect the continuous use of the isolator.

[0015] Preferably, a filter membrane is fixedly connected to the air outlet pipe near its end; the filter membrane has multiple air vents on its surface.

[0016] By adopting the above technical solution, the vent holes intercept exhaust impurities, the porous design filters without obstructing flow, the filter membrane is easy to install and the filter material is easy to replace, which improves exhaust cleanliness, reduces daily maintenance costs, and is suitable for high-frequency experimental operations.

[0017] Preferably, the top of the mounting housing is hinged with a connecting cover; the surface of the connecting cover has multiple ventilation holes; and a filter screen is fixedly connected to the center of each ventilation hole.

[0018] By adopting the above technical solutions, the ventilation holes further filter out tiny impurities and enhance cleanliness. The hinged structure makes it easy to open and close the connecting cover and clean the inside of the mounting shell. The filter screen can be replaced separately, which not only ensures the environment inside the soft membrane but also improves the ease of use of the equipment.

[0019] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this easy-to-disassemble mouse feeding soft-pack isolator simplifies the disassembly and assembly process by using a sliding splice of the horizontal and vertical supports and a locking limit rod. It avoids seal attenuation due to repeated disassembly and assembly by using sealing gaskets in the air outlet and inlet pipes and a modular air path structure. Furthermore, it adapts to different scenarios by using a sliding slider for hoisting and a variable frame. Ultimately, it solves the problems of complex disassembly and assembly, easy seal attenuation, and difficulty in scenario adaptation of soft-pack isolators, and significantly improves the efficiency of experimental operations.

[0020] Compared with existing technologies, this easy-to-assemble and disassemble mouse rearing soft-pack isolator achieves flat installation of the soft pack membrane without the need for multiple people through the sliding adjustment of the slider and the stable lifting structure of the hook. Combined with the hinged opening and closing design of the connecting cover and the high-efficiency filtration function of the filter membrane, it allows cleaning, maintenance, and gas replacement during experiments without interrupting the rearing environment. Furthermore, the stable locking of the limiting rod and the leak-proof characteristics of the sealing gasket ensure good sealing performance even after long-term repeated use. At the same time, it reduces equipment wear and maintenance costs, provides a continuously stable clean environment for laboratory animals, and further improves the accuracy of experimental data.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0027] As attached Figures 1 to 4The mouse rearing soft-pack isolator shown includes a horizontal support 1, a vertical support 12, and a soft pack 13. Quick-connect components 11 are provided at both ends of the horizontal support 1. The horizontal support 1 is slidably connected to the vertical support 12 via the quick-connect components 11, and multiple horizontal supports 1 and vertical supports 12 are combined to form a fixed frame. A soft pack 13 with an antibacterial and anti-corrosion coating sprayed on the inner wall and a transparent observation window is installed on the top of the horizontal support 1. An air outlet pipe 14 and an air inlet pipe 15 are fixedly connected to one side of the soft pack 13, and a sealing gasket is adhered at the connection between the soft pack 13 and the air outlet pipe 14 and air inlet pipe 15. The end of the air inlet pipe 15 is connected to an oxygen supply unit. An installation component 16 for suspending the soft pack 13 is provided in the middle of the quick-connect components 11.

[0028] The horizontal support 1 is slidably adapted to the vertical support 12 via quick-connect components 11 at both ends, quickly splicing them into a fixed frame that can adapt to different spaces. The soft film 13 is fixed by relying on the top of the horizontal support 1. The air outlet pipe 14 and air inlet pipe 15 on one side of the soft film 13 achieve air path sealing with the adhesive sealing gasket. The air inlet pipe 15 is connected to external equipment to deliver gas. The installation component 16 in the middle of the quick-connect component 11 assists in the quick hoisting of the soft film 13, so that the frame can be disassembled and assembled without tools. The sealing gasket prevents air path leakage. The overall adaptability is strong, and it can quickly complete the layout of different scenarios, greatly improving the turnover efficiency of the equipment. Example 2

[0029] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: As a preferred embodiment, the T-shaped block 2 is embedded in the groove 21 of the vertical support 12 to achieve sliding. The relative position of the horizontal support 1 and the vertical support 12 can be flexibly adjusted according to the size of the soft film 13. After the adjustment is in place, the limiting mechanism 22 at the top of the T-shaped block 2 locks the connection between the two to prevent the frame from loosening and shifting. The locking process is simple and efficient. No additional fasteners are required for disassembly and assembly, which ensures the structural stability of the frame and adapts to the space requirements of different experimental scenarios.

[0030] In a preferred embodiment, rotating the limiting rod 31 inside the threaded hole 3 at the top of the T-shaped block 2 causes its top protrusion to press against the side wall of the vertical bracket 12, restricting the sliding of the T-shaped block 2 and the slide groove 21, thus stabilizing the frame node connection. The twisting operation is effortless and easy to use. The protrusion increases the locking contact area, making the connection more stable and less prone to loosening. When disassembling or assembling, simply rotate the limiting rod 31 in the opposite direction to unlock. The operation is convenient and there is no wear on the parts. It can still maintain a stable locking effect after long-term use.

[0031] In a preferred embodiment, the slider 42 slides and adjusts its position on the horizontal support 1. After the bottom hook 43 is inserted into the lifting hole 41 of the top fixing plate 4 of the soft film 13, the slider 42 slides to adapt to the lifting point of the soft film 13, smoothly lifting the soft film 13 and making it fit the frame. The sliding adjustment allows the hook 43 to adapt to the lifting requirements of different soft films 13. The cooperation between the hook 43 and the lifting hole 41 makes the soft film 13 installed more flat, and the lifting can be completed without additional fasteners, simplifying the installation steps of the soft film 13.

[0032] As a preferred embodiment, the mounting shell 5 at the end of the exhaust pipe 14 has a built-in exhaust fan 51. When the exhaust fan 51 is running, it generates a directional airflow driving force, which accelerates the flow of gas inside the soft membrane 13 to the exhaust pipe 14, promotes gas circulation and renewal, ensures the stability of the gas environment inside the soft membrane 13, and does not affect the continuous use of the isolator, thus meeting the needs of long-term experiments.

[0033] In a preferred embodiment, the surface of the filter membrane 6 near the end of the air outlet pipe 14 is provided with air vents 61. When the airflow flows through the air outlet pipe 14, the air vents 61 intercept particulate impurities, preventing external pollutants from invading the soft membrane 13 in the reverse through the exhaust path. The porous structure of the air vents 61 filters impurities without obstructing the airflow, ensuring smooth exhaust.

[0034] In a preferred embodiment, the top of the mounting shell 5 is connected to the connecting cover 7 via a hinged structure. The connecting cover 7 can be opened and closed flexibly. When the airflow is discharged through the ventilation hole 71 of the connecting cover 7, the built-in filter in the ventilation hole 71 further filters out tiny impurities. Opening and closing the connecting cover 7 also makes it easy to clean the dust accumulated inside the mounting shell 5. The dual filtration enhances the cleanliness of the exhaust. The filter can be replaced separately, which not only ensures the environmental quality inside the soft membrane 13, but also simplifies maintenance operations.

[0035] In this embodiment, the soft film 13 and the exhaust fan 51 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here.

[0036] The working process of this utility model is as follows: First, slide the T-shaped blocks 2 at both ends of the horizontal support 1 into the middle of the sliding groove 21 of the vertical support 12. After adjusting the position, tighten the limiting rod 31 in the threaded hole 3 at the top of the T-shaped block 2. Fix the relative position of the horizontal support 1 and the vertical support 12 through the limiting mechanism 22 and splice them into a fixed frame. Then, slide the slider 42 on the horizontal support 1 so that the hook 43 at the bottom of the slider 42 passes through the lifting hole 41 of the top fixing plate 4 of the soft film 13, lift the soft film 13 and attach it to the frame. Finally, bond and seal the air outlet pipe 14, the air inlet pipe 15 and the soft film 13. Install the mounting shell 5 with the exhaust fan 51 and the filter membrane 6 at the end of the air outlet pipe 14 to complete the overall assembly.

[0037] Subsequently, the air inlet pipe 15 is connected to the oxygen supply machine to deliver clean gas into the soft membrane 13, and the exhaust fan 51 in the middle of the outlet pipe 14 is activated to accelerate the air circulation inside the isolator; after the airflow passes through the air vents 61 of the filter membrane 6, it is discharged through the ventilation holes 71 of the connecting cover 7 to maintain a clean breeding environment inside the isolator; during operation, the horizontal support 1 and the vertical support 12 maintain the stability of the frame through the T-shaped locking block 2, the sliding groove 21 and the limiting rod 31, and the slider 42 and the hook 43 continuously and steadily lift the soft membrane 13 to ensure the integrity of the isolation and sealing space; the above is the working principle of this easy-to-disassemble mouse breeding soft membrane isolator.
