Description
Technical Field
[0001] This utility model relates to the technical field of laboratory animal isolation devices, specifically a biosafety double-layer constant temperature and humidity poultry isolation device. Background Technology
[0002] A biosafety isolator is a biosafety isolation device used to house specific pathogen-free (SPF) or germ-free laboratory animals. Ordinary laboratory animals and their housing environments may harbor pathogens such as bacteria, viruses, and parasites, which can interfere with animal-based biological experiments, drug development experiments, or other scientific research, leading to a lack of reliability and reproducibility in experimental results. Therefore, for experiments requiring high stability or those needing to control biosafety risks at the source, biosafety isolators should be used to house SPF or germ-free animals, completely isolating them from the external environment and controlling pathogens such as bacteria and viruses in both the animals and their environment, thus achieving stable and reliable experimental results. With the rapid development of biological sciences, isolators are divided into positive pressure isolators and negative pressure isolators. Positive pressure isolators are mainly used for housing clean-grade animals to prevent the introduction of external sources of infection; negative pressure isolators are mainly used for infectious laboratory animals to ensure that infectious materials do not spread.
[0003] Currently, the quality control of airflow into the isolation chamber of existing isolation devices for poultry laboratory animals is mainly achieved through disinfection mechanisms and filters. These mechanisms disinfect and filter impurities such as microorganisms and bacteria in the incoming airflow that could affect the normal growth of laboratory animals (poultry). The actual air quality is generally obtained through a detector inside the isolation chamber. If the disinfection mechanism or filter malfunctions, resulting in poor disinfection and filtration effects and deterioration of air quality within the isolation chamber, the isolation device must be shut down immediately, and the laboratory animals transferred to another isolation device. Conventional devices lack a structure that allows for rapid switching between flow, disinfection, and filtration channels, making it difficult to quickly respond to malfunctions in the incoming air disinfection and filtration equipment. This affects the normal growth of laboratory animals, the experimental process, and results in insufficient biosafety. Utility Model Content
[0004] The purpose of this invention is to provide a biosafety double-layer constant temperature and humidity poultry isolation device to address the problem that existing isolation devices for poultry laboratory animals are unable to quickly respond to malfunctions in air intake disinfection and filtration equipment, which affects the normal growth of laboratory animals, the experimental process, and the lack of biosafety.

[0013] As a further description of the above technical solution:
[0014] The sealing structure includes a sealing box, an adjusting piston, and an adjusting rod. The adjusting piston is slidably disposed within the sealing box and divides the inner cavity of the sealing box into two independent cavities. A pressure regulating connector for connecting to an external air pressure regulating device is provided on the sealing box. The air pressure regulating device is associated with the detector. The inner cavity of the pressure regulating connector is connected to one of the independent cavities. The adjusting rod passes through an opening on the side of the sealing box and is sealed through an opening on a branch of the multi-channel structure via a sealing block, thus being inserted into the inner cavity of the branch of the multi-channel structure.

[0016] The two adjusting rods correspond to the air inlet and air outlet openings of the same branch of the multi-channel structure, respectively, and are provided with wedge-shaped guide blocks at their inner ends, which correspond to the wedge-shaped surfaces on both sides of the end of the adjusting piston. An elastic sleeve is provided between the wedge-shaped guide blocks and the inner wall of the sealing box, and the elastic sleeve is fitted onto the inner end of the adjusting rod.
[0017] As a further description of the above technical solution:
[0018] The housing is provided with a guide side plate on the side of the adjusting rod.

[0027] In summary, by adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0028] 1. When using the experimental animal poultry isolation device of this utility model, the air supply mechanism draws outside air into the isolation chamber and squeezes out the air inside the isolation chamber to achieve air flow and ensure clean air conditions inside the isolation chamber. The temperature regulation device controls the temperature of the airflow entering the isolation chamber to ensure that the temperature inside the isolation chamber is more stable, uniform and controllable.

[0029] 2. The filter components inside the filter are equipped with multiple independently connected branches of a multi-channel structure. The detector detects microorganisms, bacteria, and other impurities that may affect the normal growth of experimental animals in the airflow entering or exiting the isolation chamber. If the airflow passing through the filter is found to contain such substances (indicating a malfunction in the filter components), the multi-channel structure switches between open and closed states through a blocking structure. The branch corresponding to the malfunctioning filter component is blocked to facilitate maintenance, while the other normally functioning branch of the filter component is opened simultaneously. This achieves rapid switching of the purification flow channel and continuous air supply, ensuring the cleanliness and sterility of the air entering the isolation chamber, thereby improving the biosafety of the isolation device.
[0030] 3. By placing the outer side of the heating equipment inside the device within the heat dissipation cavity and subjecting it to air showering, heat accumulation is prevented from causing temperature fluctuations in the isolation chamber, which could affect the stability of temperature control and the normal growth of experimental animals.
[0031] 4. The isolation device is arranged with upper and lower double-layer isolation chambers, which can facilitate the separation of the daily growth area and experimental area of experimental animals, avoid the influence between experimental animals, ensure the normal growth of experimental animals, and improve the convenience of experimental operation.

[0044] Please see Figure 1-4 This utility model provides a technical solution: a biosafety double-layer constant temperature and humidity poultry isolation device, comprising:
[0045] The main body of the device 1 has a first isolation chamber 2 and a second isolation chamber 3 arranged vertically inside it; Figure 2 The opening on the left side of the central isolation chamber is used for sealed docking with other experimental devices through the connecting channel;
[0046] The air supply mechanism includes an air inlet filter 4 and an air outlet filter 5. The air inlet filter 4 and the air outlet filter 5 are respectively installed on the first isolation chamber 2 and the second isolation chamber 3. One end of the air inlet filter 4 and the air outlet filter 5 are respectively connected to the air inlet pipe 7 and the air outlet pipe 8, and the other end is connected to the inner cavity of the first isolation chamber 2 or the second isolation chamber 3 through the ventilation port 6.
[0047] A channel switching mechanism, located within the housings of the inlet filter 4 and outlet filter 5, and at the filter assembly 12, includes a multi-channel structure and a blocking structure. Each branch of the multi-channel structure is independently connected to a different filter assembly 12. A detector 13 is installed on the outlet side of the filter assembly 12. The blocking structure is used to switch the connection and disconnection states of a single branch of the multi-channel structure, and is associated with the detector 13. The detector 13 is used to detect microorganisms, bacteria, and other substances that affect the normal growth of experimental animals (poultry) in the airflow entering or exiting the isolation chamber. If the airflow passing through the filter (which disinfects and filters the airflow) is found to contain such substances (indicating a malfunction in the filter assembly 12), the blocking structure switches the connection and disconnection states of the branches of the multi-channel structure, blocking the branch corresponding to the malfunctioning filter assembly 12 for maintenance, and simultaneously opening the other normally functioning branch of the filter assembly 12. This achieves rapid switching of the purification flow channel, ensuring the cleanliness and sterility of the airflow entering the isolation chamber.
[0048] The air supply mechanism is equipped with a temperature regulating device, and the main body 1 of the device is equipped with a humidity regulating device 9 that is independently connected to the first isolation chamber 2 and the second isolation chamber 3. The water vapor outlet of the humidity regulating device 9 is connected to the inner cavity of the first isolation chamber 2 and the second isolation chamber 3. Both the temperature regulating device and the humidity regulating device 9 are existing technologies. They control the temperature of the airflow entering the isolation chamber and inject the heated and evaporated water vapor into the isolation chamber or the air supply mechanism at an adjustable flow rate through a control valve to ensure a constant temperature and humidity growth environment within the isolation chamber.
[0049] The multi-channel structure includes an air inlet tee pipe 10 and an air outlet tee pipe 11, with branches of the air inlet tee pipe 10 and the air outlet tee pipe 11 respectively connected to the air inlet side and the air outlet side of the filter assembly 12.
[0050] Specifically, the sealing structure includes a sealing box 14, an adjusting piston 15, and an adjusting rod 17. The adjusting piston 15 is slidably disposed within the sealing box 14, dividing the inner cavity of the sealing box 14 into two independent cavities. A pressure regulating connector 16 is provided on the sealing box 14 to connect to an external air pressure regulating device. The air pressure regulating device is associated with the detector 13. The inner cavity of the pressure regulating connector 16 connects to one of the independent cavities. The adjusting rod 17 passes through an opening on the side of the sealing box 14 and is sealed through an opening on a branch of the multi-channel structure via a sealing block 18, then inserted into the inner cavity of the branch of the multi-channel structure. The two adjusting rods 17 correspond to the air inlet and outlet openings of the same branch of the multi-channel structure, respectively, and have wedge-shaped guide blocks 30 at their inner ends, corresponding to the wedge-shaped surfaces on both sides of the end of the adjusting piston 15. An elastic sleeve 31 is provided between the wedge-shaped guide block 30 and the inner wall of the sealing box 14, and the elastic sleeve 31 is fitted onto the inner end of the adjusting rod 17. The housing is provided with a guide plate 32 on the side of the adjusting rod 17. When the above structure is used, as... Figure 3 , 4When the detector 13 detects impurities in the airflow of the corresponding branch, it associates with the air pressure regulating device (existing technology, used to regulate the air pressure in the closed cavity by introducing or extracting gas) to pressurize or depressurize the independent cavity. This causes the regulating piston 15 to slide within the sealed box 14 under the air pressure formed by the pressure difference between the two ends, and pushes the wedge-shaped guide block 30 through the wedge surface, causing the corresponding regulating rod 17 to be pushed outward. The sealing block 18 is inserted into the corresponding branch of the multi-channel structure to block the branch corresponding to the faulty filter component 12 for maintenance. At the same time, the other branch of the filter component 12 that is operating normally is opened to achieve rapid switching of the purification flow channel, ensuring the cleanliness and sterility of the air entering the isolation chamber. That is, the elastic kit 31 pulls the moving sealing block 18 inward, so that the sealing block 18 of the regulating rod 17 is extracted from the normally operating branch of the multi-channel structure. The branch is connected, and flow, disinfection, and filtration can be performed.
[0051] The main body 1 of the device is provided with doors 19 in the first isolation chamber 2 and the second isolation chamber 3 respectively. Operating gloves or glass partitions are provided on the windows 20 of the doors 19 to facilitate the observation of the growth of experimental animals in the isolation chamber and the operation of corresponding experimental content.
[0052] Positioning platforms 21 are installed on the side walls of both the first isolation chamber 2 and the second isolation chamber 3. A first supporting mesh frame 22 or several L-shaped second supporting mesh frames 23 are laid on the positioning platform 21 at intervals. The two isolation chambers have different uses: the upper first isolation chamber 2 provides a growth environment for experimental animals, while the lower second isolation chamber 3 uses the second supporting mesh frames 23 to separate the experimental animals, thus facilitating animal experimental operations.
[0053] Lighting lamps 25 are installed on both the first isolation chamber 2 and the second isolation chamber 3. A first heat dissipation cavity 26 and a second heat dissipation cavity 27 are respectively spaced between the first isolation chamber 2 and the main body 1 and the second isolation chamber 3. The lighting lamps 25 are located within either the first or second heat dissipation cavity 26. The air inlet pipe 7 extends into either the first or second heat dissipation cavity 26 and is equipped with a butterfly valve 24. Considering that the electrical equipment in the isolation chamber generates heat during operation, the ventilation design within the heat dissipation cavity improves the heat dissipation efficiency of the equipment, thereby further ensuring constant temperature growth conditions within the isolation chamber and utilizing the heat from the equipment. This allows the airflow to enter the air supply mechanism at a certain temperature, reducing the energy consumption required to heat the incoming airflow and achieving energy-saving effects. The butterfly valve 24 controls the air inlet rate (wind speed within the heat dissipation cavity) of the air inlet pipe 7, ensuring stable airflow into the isolation chamber while maintaining efficient equipment heat dissipation performance.
[0054] The bottom of the first isolation chamber 2 and the second isolation chamber 3 are provided with a sewage pipe 28, which extends along the equipment cavity 29 to the outside of the main body 1 of the device. This allows waste generated inside the isolation chamber to be discharged, ensuring a clean operating environment inside the isolation chamber.
[0055] The working principle of a biosafety double-layer constant temperature and humidity poultry isolation device in this embodiment includes: during use, the air supply mechanism draws outside air into the isolation chamber and squeezes out the air inside the isolation chamber to achieve air flow and ensure clean air conditions inside the isolation chamber. The temperature regulation device controls the temperature of the airflow entering the isolation chamber to ensure that the temperature inside the isolation chamber is more stable, uniform and controllable. The humidity regulation device 9 injects the water vapor evaporated by heating into the isolation chamber or the air supply mechanism at an adjustable flow rate through the control valve to ensure a constant temperature and humidity growth environment inside the isolation chamber. The filter assembly within the filter is equipped with multiple independently connected branches of a multi-channel structure. The detector 13 detects microorganisms, bacteria, and other impurities in the airflow entering or exiting the isolation chamber that could affect the normal growth of experimental animals (poultry). If the airflow passing through the filter is found to contain these substances (indicating a malfunction in filter assembly 12), the multi-channel branch connection is switched via a blocking structure. The branch corresponding to the malfunctioning filter assembly 12 is blocked for repair, while simultaneously opening the other normally functioning branch of filter assembly 12. This achieves rapid switching of the purification flow channel and continuous air supply, ensuring the cleanliness and sterility of the air entering the isolation chamber, thereby improving the biosafety of the isolation device. By placing the heating elements on the outside of the device within a heat dissipation cavity and subjecting them to air showering, heat accumulation is prevented from causing temperature fluctuations within the isolation chamber, which could affect temperature control stability and the normal growth of experimental animals. The isolation device features a double-layered isolation chamber layout, facilitating the separation of the daily growth area and experimental area for experimental animals, preventing interference between animals, ensuring their normal growth, and improving the convenience of experimental operations.
[0056] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
