CAGE RACK SYSTEM AND METHOD FOR SAMPLING AIRBORNE PARTICLES FROM A CAGE RACK SYSTEM
First Claim
1. A cage rack system for animals comprising:
- (a) means for accommodating a plurality of cages ventilated individually or in groups, at least the majority of the cages comprising at least one air-inlet and at least one air-outlet,(b) an air guidance system used for delivering air to the air-inlet and/or collecting air from the air-outlet,(c) at least one sampling unit used for collecting airborne particles from the air,wherein,(d) the sampling unit is adapted to collect the airborne particles by a cyclonic flow path to cause a separation of the particles from the air.

Abstract
The present invention is related to a cage rack system for animals, particularly for laboratory animals. This system can accommodate or comprises a plurality of cages ventilated individually or in groups. At least the majority of the cages comprise at least one air-inlet and at least one air-outlet. The cages can be selected according to the race, size, the number and/or conditions of the animals. The invention further comprises an air guidance system for delivering air to the air-inlet and/or collecting air from the air-outlet with integral or separated conduits. Further, there is provided at least one sampling unit for collecting airborne particles from the air; the sampling unit being adapted to collect the airborne particles by a cyclonic flow path to cause a separation of the particles from the air. The sampling unit can have one or more components and can be arranged for analysing, evaluating, controlling and/or monitoring the incoming air and/or the outgoing air. The incoming air can be checked in order to have a basis for comparing the respective results with the results from one or more components of the air guidance system analysing, evaluating, controlling and/or checking the outgoing air. Alternatively or additionally to the cyclone the sampling unit can be provided so as to be replaceably insertable in one or more of the conduits.
