COLLAPSIBLE CANISTER LINER FOR MEDICAL FLUID COLLECTION
First Claim
1. A medical fluid collection system comprising:
- a canister defining an open end; and
a liner assembly including;
a lid removably attachable to the open end of the canister, the lid including a vacuum port and a collection port; and
a collapsible liner dimensioned for placement within the canister and biased to a vertically collapsed position during operation, the liner including;
a flexible film bag extending longitudinally between a top portion coupled to the lid and a closed bottom portion and defining an interior, andat least one support element apart from the lid and disposed generally laterally relative to the flexible bag direction of extension;
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 pressure by way of the vacuum port, the at least one support element constrains a lateral collapse of the bag; and
wherein the canister includes a second vacuum source port located remotely from the lid so as to subject a space between the collapsible liner and the canister to a second vacuum commensurate to the vacuum applied to the interior of the bag, the second vacuum source port being configured to fluidly connect the space between the liner and the canister with a vacuum source and positioned so as to inhibit vertical collapse of the bag during operation.

Abstract
A collapsible liner for use in a canister of a medical fluid collection system is disclosed. The liner includes a flexible bag extending longitudinally between a top portion opposite a closed bottom portion, and at least one support element connected to the bag and disposed generally laterally relative to a length of the bag. When an interior of the bag is subjected to a vacuum, the at least one support element limits an extent of lateral collapse while permitting longitudinal collapse. The canister includes a second vacuum source port located remotely from the lid so as to subject a space between the collapsible liner and the canister to a second vacuum commensurate to the vacuum applied to the interior of the bag.
