The laboratory animal room is generally composed of breeding room, health observation room, isolation and quarantine room, various laboratories (surgical operation, experimental treatment anatomy, postoperative management, disease diagnosis, treatment, biochemical examination, microbial quarantine, feed nutrition analysis and special feed acquisition. Dispensing room, etc.). As well as storage room, cleaning preparation room, washing and disinfection room, staff room (including office, shower room, changing room, etc.), corridor (clean area and polluted area), waste treatment facilities, computer room & substation, etc. Its plane layout should make the flow route of people, animals and objects reasonable and easy to operate. Strictly distinguish the clean area and the contaminated area to ensure the health of people and animals and ensure the accuracy of the experiment (see the figure for the flow routes of people, animals and objects).
Decoration and construction design of animal room | animal laboratory | animal laboratory:
The plane size of the laboratory animal breeding room is determined according to comprehensive research such as feeding quantity, feeding method, cage frame specification, arrangement method, indoor environment, feeding management and operation method. In order to avoid the gradient of temperature and humidity in the vertical direction, the height of the cage should not exceed 1.8 meters, and the height of the ceiling should be within the range of 2.2 to 3 meters. The width of the corridor should be convenient for operation and handling of materials and equipment, and should not be less than 1.3 meters. The size of the cleaning preparation room must be determined according to the work content and the space occupied by facilities such as disinfection and sterilization devices. Clean the preparation room, the clean corridor and the washing room are separated by walls, and no cracks are allowed in the walls.
The ground should be flat and not slippery, water-proof, water-proof, resistant to liquid corrosion and wear-resistant. For rooms with strict environmental requirements, consider choosing materials with low dust emission. The corners of the wall and ground should be smooth and without edges and corners. The inner walls should be smooth, water-resistant, wear-resistant, and resistant to disinfectant corrosion. The angle between wall and wall, wall and ceiling or beam should be smooth and no corners. The ceiling is generally not under pressure, and a thin cement board coated with waterproof material is used, which can withstand the corrosion of water washing and disinfection water. Breeding rooms usually do not have external windows, nor do internal windows between the breeding rooms to avoid interference. The door of the breeding room should be an aluminum alloy closed door, and the opening direction should pay attention to the indoor and outdoor pressure gauges. The door between the barrier and the non-barrier shall be provided with a device that cannot be opened unless certain conditions are met. Wood structures are generally only used as simple temporary buildings; mixed structures are mostly single-storey buildings. The reinforced concrete frame structure has good integrity and small deformation, and should be used in multi-storey buildings. Steel skeleton, galvanized corrugated metal plate, with polystyrene rigid foam board as insulation layer, has good airtight insulation performance.
