Problems solved by technology
At the same time, it is often necessary to change the cage during the breeding process, which is likely to cause the suspension of dust particles such as feed bedding. Because of the design of the position of the air intake and exhaust in the existing isolator, eddy currents and partial airflow often appear in the control of air cleanliness and airflow organization. The wind speed does not meet the sterility requirements and other deficiencies
The position and structure of the air intake and exhaust of the isolator often lead to a non-parallel flow state inside, and it is easy to cause pathogenic organisms to gather in the vortex area, which is not conducive to improving the cleanliness of the air and the stability of the sterile state
At present, the internal design of commonly used aseptic isolators is non-parallel flow and has no functional area separation. There is no parallel flow aseptic isolator that can effectively ensure air cleanliness.

Embodiment Construction
[0019] like Figure 1-Figure 3 As shown, a parallel flow aseptic isolator includes a sterile isolator main body, an orifice plate 3, a high efficiency filter 2, a plenum box 1, a blower 19, an IVC cage air supply system 9 and an IVC cage exhaust system 16. The main body of the aseptic isolator, the orifice 3, the high-efficiency filter 2, the plenum 1 and the air blower 19 are connected in sequence, and the main body of the aseptic isolator is equipped with gloves 11 and sterile / non-clean items (animals) ) transfer system 10, the underside of the air outlet in the upper middle part of the main body of the isolator is provided with a sleeve 8, which is used for the IVC system when the IVC cage air supply system 9 and the IVC cage air exhaust system 16 are selectively used as required The connection between the pipeline and the external fan. The bottom of the main body of the aseptic isolator is provided with a support structure 13, the bottom of the support structure 13 is pro...

The invention discloses a parallel flow sterile isolator. The parallel flow sterile isolator comprises a sterile isolator main body, a pore plate, a high efficiency filter, a static pressure box, a forced draft fan, an IVC (individually ventilated cage) cage air supply system and an IVC cage air exhausting system, wherein the sterile isolator main body, the pore plate, the high efficiency filter, the static pressure box and the forced draft fan are sequentially communicated, a pair of gloves and a transmission system are arranged on the sterile isolator main body, and a supporting structure is arranged at the bottom of the sterile isolator main body. The parallel flow sterile isolator has the advantages that positions of supplying air and exhausting the air are changed, an up-supply and up-exhaust mode is designed, and the IVC cage air supply system and air exhausting systems are additionally arranged inside, so that the interior of an existing sterile isolator forms two functional areas; meanwhile, the IVC system at the rear half of the isolator further guarantees cleanliness of the air, and operation space of the front half of the isolator is changed into a parallel flow from a non-parallel flow, so that the parallel flow sterile isolator has positive significance in maintenance of the air cleanliness when impurities appear in an operation of changing a cage for animals, reduction of dust particulate matters as well as stable air exchange, temperature and humidity.
Description
technical field [0001] The invention relates to a parallel flow aseptic isolator. Background technique [0002] Isolation system: The isolation system is sealed or has a microbial filtration system (HEPA) to provide air and is self-cleaning. When enclosed, use only decontaminated interior surfaces or use rapid transfer channels for material transfer. When open, materials are only allowed to pass in and out through specific openings that have been designed and verified to discharge contamination. It can be used to isolate active mixtures during aseptic processing or for both sterilization and isolation. [0003] Experimental animals are widely used in a large number of modern scientific experiments and research, and are regarded as "living precision instruments" in disciplines such as bioengineering, genetics, immunity, tumors, medical and health care, family planning, environmental protection, animal husbandry, and military medicine. " and "living reagents". According to...
