A cage changing and disinfecting system for spf animal houses

Abstract

This invention discloses a cage changing and disinfection system for SPF animal rooms, comprising a base frame and single-layer cage assemblies. The base frame is supported on a plane, and the single-layer cage assemblies are mounted on the base frame. Multiple single-layer cage assemblies are stacked on top of each other on the base frame. Each single-layer cage assembly includes an outer cage frame, partitions, a cage compartment, and a cage changing, disinfection, and rinsing assembly. The outer cage frame has horizontally arranged tracks on its inner side. Two sets of partitions are vertically distributed on the inner side of the outer cage frame, dividing it into two placement chambers and a transfer chamber. The cage compartment is located within the placement chamber and can slide with the tracks. A rack is located on one side of the lower end of the cage compartment, and a guide plate is located on the inner side of the cage compartment. Gears are also installed inside the placement chamber, driven by a stepper motor. This invention uses automatically movable cages and a transfer chamber. After the cage enters the transfer chamber, it is rinsed and disinfected by the disinfection and rinsing assembly and returns to its original position after disinfection, eliminating the need to disassemble the cage and saving time.

Description

Technical Field

[0001] This invention relates to the field of SPF animal housing, specifically to a cage changing and disinfection system for SPF animal housing. Background Technology

[0002] SPF-grade laboratory animal facilities, also known as clean animal facilities, require scientific design, construction, and strict management. An SPF clean animal facility typically consists of a housing room, health observation room, isolation and quarantine room, operating room, rooms for experimental processing and dissection, post-operative management, disease diagnosis, treatment, physiological and biochemical examination, microbiological quarantine, feed nutrition analysis, and special feed preparation, as well as storage rooms, cleaning and preparation rooms, washing and disinfection rooms, staff rooms (including offices, shower rooms, changing rooms, etc.), corridors (clean and contaminated areas), waste disposal facilities, machine rooms, and substations. Its layout should ensure a rational flow of people, animals, and materials, facilitating operations.

[0003] The feeding room is mainly used for animal feeding and observation. Traditional feeding rooms are generally cage-type rooms. During animal feeding experiments, it is necessary to regularly disinfect and clean the cage-type rooms for experimental animals. Therefore, the animals need to be taken out of the cages and placed in temporary cages. After disinfecting and cleaning the cage-type rooms, the animals are taken out of the temporary cages. Since the disinfection and cleaning of cage-type rooms is generally done by disassembly and cleaning, it takes a long time and is not conducive to changing cages in the animal room. Therefore, this invention provides a cage changing and disinfection system for SPF animal rooms. It uses an automatically movable cage and is equipped with a cage transfer chamber. After the cage enters the cage transfer chamber, it is rinsed and disinfected by the disinfection and rinsing components, and then returned to its original position after disinfection, without the need to disassemble the cage.
