The collection canister has ports to introduce a vacuum from the vacuum source into the collection canister. A ball float is provided to substantially close the suction port in response to one of collection of a predetermined volume of exudate in the collection canister, tilting of the collection canister beyond a predetermined angle of orientation or inversion of the collection canister.
