Description

In-situ decontamination equipment for independent ventilation cage frames of rats and mice

Technical Field

The utility model relates to the technical field of biological medicine, further relates to the raising and management of living experimental animals, and in particular relates to in-situ decontamination equipment for independent ventilation cages of rats and mice.

Background

With the development of life sciences and biomedicine, demands for living experimental animals are increasing, in recent years, large rodent experimental animals (particularly, rats) raising facilities are increasing in size, purification levels are also increasing gradually, and Independent Ventilation Cages (IVCs) are added in barrier facilities to ensure safety of experimental animals, environments and laboratory staff.

The IVC is provided with an air inlet and outlet system, fresh air is collected from the environment, and exhaust gas circulated through the cage box is discharged out of the barrier system. In the operation process, dust of padding can be accumulated on the inner wall of an air pipe and the pipe orifice of the IVC, and the long-time operation can influence the operation efficiency and the service life of the machine. The barrier facility is an SPF-class environment, the cage needs to be periodically moved out of the barrier facility for cleaning, and then is transferred into the barrier facility after disinfection, so that the whole process is complex in procedure, large in workload, expensive in cleaning equipment and high in pollution risk.

The current general method for cleaning and sterilizing independent ventilation cages of large and small mice is to take down the cage box on the equipment, disconnect the exhaust pipe connected with the main ventilation pipe, remove the cages out of the barrier facility through the exit buffer, and clean the cages in a special cage cleaner. After cleaning, the waste water is disinfected from the large-scale transfer cabin and then is transferred into facilities for reconnection installation and use. There are a number of problems with this approach: and (1) the procedures are complicated and the workload is large. This is equivalent to reinstalling and debugging the IVC cage once again into and out of the barrier. (2) involving a large number of areas and having a high risk of contamination. The IVC cage needs to enter the cleaning hall through a polluted corridor and exit buffer, and after cleaning is finished, the IVC cage needs to be conveyed back to the feeding room through a large-scale transfer cabin and a clean corridor. Extensive transfer increases the probability of contamination. (3) the cleaning equipment is expensive and occupies a large area. Typical IVC cages are about 2 meters high, about 1.8 meters long and 60CM wide, and small instruments cannot be accommodated and passed through. Therefore, large transfer tanks and cabinet washers are necessary. Currently, the domestic large-scale transfer cabin is about 70 ten thousand yuan/station, and the domestic cabinet type cage washing machine is about 100 ten thousand yuan/station, and belongs to expensive equipment. Moreover, in laboratories at the level of barrier facilities, these two types of equipment occupy approximately 1/6 of the area of the washing lobby, squeezing the area of the cage washing operation area. And (4) the energy consumption is too high, the environment is not protected, and the whole batch cleaning period is long. The large-scale transfer cabin and the cabinet type cage washing machine have larger electricity consumption. Meanwhile, the cabinet type cage washing machine has larger water consumption, and consumes about 1-2 tons of water after one cycle. And only one cage at a time, each cage set takes about half a day from cleaning to reuse. For facilities with a feeding capacity above 5000 cages, it takes about one month for the entire cage to be washed once.

1. the IVC cage is cleaned in situ, disinfected in situ and does not need to be moved out of the room. Reduces the workload and reduces the risk of microbial contamination in the transportation process.

2. The machine body is small, and the incoming barrier is convenient. The equipment has the volume of about 60cm multiplied by 100cm, the weight of no more than 50 kg, the appearance of the equipment is made of totally-enclosed smooth materials, the inside of the equipment is provided with a self-cleaning disinfection function, and the inside of the equipment is disinfected while the surface disinfection is carried into the barrier so as to prevent pollutants from being carried into the barrier.

3. The visual operation, the full automatic control of the flow, the cleaning and disinfecting flow is greatly shortened. The device designs the liquid crystal operation screen, belongs to one-key operation, and is simple and easy to learn. In the whole process, the high-pressure sterile air is used for cleaning for about five minutes, the aerosol is sterilized for about five minutes, the sterile air is used for removing the aerosol residues for about five minutes, and the cleaning and sterilizing of each set of cage is completed for about 30 minutes after the IVC host is disassembled, connected with equipment, dried in the air in a sterile manner, reconnected with the IVC host and the like.

4. Low energy consumption, low noise, low carbon, environmental protection and low cleaning and disinfection cost. The whole load of the equipment is about 8KW, an inlet static high-pressure air pump and a fan are used, the noise during the whole load operation is less than 50dB, and the noise requirement in the barrier environment is met.
