Claim:
A medical fluid waste collection liner assembly for use with a medical fluid collection canister comprising: a lid configured to be removably attached to the canister, the lid including a vacuum port and a collection port; and a liner coupled to the lid, the liner including: a flexible film bag extending longitudinally between a top portion and a closed bottom portion and defining an interior, and at least one support element apart from the lid and connected to a segment of the bag; wherein the vacuum port and the collection port are in direct fluid communication with the interior of the bag, wherein when the interior of the bag is subjected to a vacuum during evacuation of fluid waste, the bag, except for the segment of the bag coupled to the at least one support element, laterally collapses so that the closed bottom portion and the at least one support element are displaced longitudinally toward the lid, and wherein the closed bottom portion is flexibly configured to longitudinally displace further into the interior when the at least one support element reaches a limit of longitudinal displacement toward the lid for removing substantially all of the fluid waste from the bag.
