Description

Technical Field

[0001] This invention belongs to the field of isolator technology, and particularly relates to an SPF double-layer poultry experimental chicken isolator. Background Technology

[0002] In scientific research activities such as breeding SPF (specific pathogen-free) chickens, developing biological vaccines, and constructing models of avian infectious diseases, experimental animals must be raised in a strictly sterile environment to avoid interference from external microorganisms with experimental results. Although traditional single-layer poultry isolators can meet the basic sterility requirements.

[0003] However, the space utilization rate is low, the single-layer structure occupies a large area, and for experiments that require a large sample size for control, multiple devices often need to be connected in parallel, resulting in a shortage of laboratory space; secondly, the operational flexibility is poor.

[0004] Furthermore, the existing isolators are mostly fixed in their internal facilities, and the drinking water pipelines are not adjustable, making it difficult to adapt to the drinking height requirements of chickens of different ages and sizes. Moreover, cleaning the bottom of the cage requires frequent manual entry, increasing the risk of contamination. The functional integration is insufficient, with components such as pass-through windows, lighting, and filtration systems scattered, resulting in uneven airflow and many dead corners, affecting the maintenance of cleanliness. Finally, they are inconvenient to move and maintain; large isolators are usually bulky and difficult to move, and the internal waste collection devices are often rudimentary, lacking convenient storage and replacement mechanisms. Summary of the Invention

[0005] The purpose of this invention is to address the following issues: Existing isolators are mostly fixed in their internal structure, with non-adjustable drinking water lines that cannot accommodate the varying drinking height requirements of chickens of different ages and sizes; frequent manual intervention is required for cage bottom cleaning, increasing the risk of contamination; insufficient functional integration, with scattered layouts of components such as pass-through windows, lighting, and filtration systems leading to uneven airflow, numerous dead zones, and compromised cleanliness; and difficulties in movement and maintenance. Furthermore, large isolators are typically bulky, difficult to relocate, and often have rudimentary internal waste collection devices, lacking convenient storage and replacement mechanisms. Therefore, this invention proposes an SPF double-layer poultry experimental chicken isolator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an SPF double-layer poultry experimental chicken isolator, comprising:

[0007] A support frame on which a lower isolation compartment is mounted;

[0008] The upper isolation chamber is connected to the lower isolation chamber. The upper and lower isolation chambers are equipped with transfer windows and several isolator glove interfaces. The bottom of both the upper and lower isolation chambers is equipped with a lower box, which contains a storage cloth. The bottom of both the upper and lower isolation chambers is equipped with a perforated mesh.

[0009] The drinking spout is mounted on the upper and lower isolation compartments via guide rails;

[0010] It contains several high-efficiency filter boxes, which are connected to the upper and lower isolation chambers. The several high-efficiency filter boxes are connected by a connecting pipe.

[0011] Furthermore, a rotating shaft is provided on the lower housing, and the storage cloth is sleeved on the rotating shaft.

[0012] Furthermore, the bottom of the aforementioned bracket is equipped with several omnidirectional casters.

[0013] Furthermore, LED pendant lights or explosion-proof lights are installed on the top of the aforementioned upper and lower isolation chambers.

[0014] Furthermore, the aforementioned isolator glove is connected to the isolator glove interface.

[0015] Furthermore, both the upper and lower isolation chambers are equipped with control boxes.

[0016] Furthermore, the aforementioned isolator glove interfaces are connected to the sides and ends of the upper and lower isolation chambers, with the isolator glove interfaces on both sides located on the mounting plate, which is detachably connected to the upper or lower isolation chamber.

[0017] The present invention provides an SPF double-layer poultry experimental chicken isolator, which divides the isolation chamber into upper and lower layers (upper isolation chamber and lower isolation chamber) by a bracket. The two can independently form a sealed sterile environment, or they can be linked through a specific pipeline or structural design. The high-efficiency filter box is connected to the upper and lower chambers through a connecting pipe to ensure that the air supplied to the two chambers is highly filtered and maintains a positive pressure sterile state. Experimenters can sterilely transfer materials through the transfer window on the chamber. By putting their hands into the gloves connected to the glove interface of the isolator, they can grasp, feed, observe or conduct experiments on the chickens in the chamber in a completely sealed environment. Since the glove interfaces are distributed on both sides and ends of the chamber, and with the help of the detachable mounting plate, the operator can work flexibly from multiple angles. The drinking nozzle is installed in the chamber through a guide rail. Depending on the chickens' growth stage (from chicks to adults), operators can adjust the height of the drinking spouts from outside the enclosure via guide rails to ensure comfortable drinking for the chickens, reduce water waste, and minimize ground dampness. The bottom of the enclosure features a perforated mesh design, allowing chicken excrement to fall through the mesh into the lower chamber. A storage cloth inside the lower chamber collects feces and leftover feed. When cleaning is required, a rotating shaft can be used to roll up the storage cloth along with the waste, allowing it to be removed through a pass-through window without needing to enter the enclosure for cleaning, greatly reducing the probability of contamination. LEDs or explosion-proof lights on the top provide ample illumination. The control box monitors and adjusts parameters such as temperature, humidity, and air exchange rate within the enclosure. The omnidirectional casters at the bottom allow the entire large isolator to be moved and positioned flexibly.

[0018] Therefore, this embodiment has the following advantages compared to the prior art:

[0019] An SPF double-layer poultry experimental chicken isolator addresses several issues with existing isolators. These include fixed internal structures, non-adjustable drinking water lines that fail to meet the varying drinking height requirements of chickens of different ages and sizes, frequent manual intervention for cage bottom cleaning increasing the risk of contamination, insufficient functional integration (dispersed layout of components such as pass-through windows, lighting, and filtration systems leading to uneven airflow, numerous dead zones, and compromised cleanliness), and difficulties in movement and maintenance. Furthermore, large isolators are typically bulky, difficult to move, and often have rudimentary internal waste collection devices lacking convenient storage and replacement mechanisms.
