A wound fluid collection system includes a canister with a chamber fluidly connected to a wound dressing in a tissue site through an inlet and also fluidly connected to a reduced pressure source through an outlet. At least a portion of the canister is collapsible and yet can be maintained in an extended state when exposed to subatmospheric pressure. The canister is releasably attachable to a supporting member.

1. A fluid collection canister for collecting bodily fluids from a tissue site by using reduced pressure provided from a reduced pressure treatment unit, comprising: a support member having a generally rigid body, a proximal end including an inlet adapted to receive bodily fluids from the tissue site and an outlet adapted to be fluidly coupled to the reduced pressure treatment unit for receiving reduced pressure, and a distal end, the support member being releasably connectable to the reduced pressure treatment unit such that, when the support member is connected to the reduced pressure treatment unit, the support member is affixed to the reduced pressure treatment unit;a container having walls forming a chamber within the container, a proximal end including an opening to the chamber adapted to be fluidly coupled to the inlet and outlet of the support member such that the chamber receives the reduced pressure from the reduced pressure treatment unit, and a distal end closing the chamber, wherein the walls have a collapsible portion allowing the container to be compressed to a first volume in a collapsed state and stretched to a second volume in an expanded state, the second volume being larger than the first volume; anda retention device adapted to couple the distal end of the container to the distal end of the support member to hold the container in the expanded state while the reduced pressure from the reduced pressure treatment unit is communicated to the chamber. 2. The canister of claim 1, wherein the support member is a carrier plate. 3. The canister of claim 1, wherein the collapsible portion is corrugated. 4. The canister of claim 1, wherein the walls further comprise a non-collapsible portion. 5. The canister of claim 1, wherein the retention device is a boss. 6. The canister of claim 1, wherein the retention device comprises a coil spring positioned within the chamber of the container. 7. The canister of claim 1, wherein the canister further comprises an interface connector comprising a container portion and an engagement plate, the container portion and the engagement plate forming an interface connector chamber, the interface connector chamber fluidly connected to the chamber of the container. 8. The canister of claim 7, wherein the interface connector further comprises the inlet and the outlet of the canister. 9. The canister of claim 8, wherein the engagement plate further comprises an aperture adapted to support an outlet hydrophobic filter at the outlet of the canister. 10. A fluid collection canister for collecting bodily fluids from a tissue site by using reduced pressure provided from a reduced pressure treatment unit, comprising: a support member having a generally rigid body, a proximal end including an inlet adapted to receive bodily fluids from the tissue site and an outlet adapted to be fluidly coupled to the reduced pressure treatment unit for receiving reduced pressure, and a distal end, the support member being releasably connectable to the reduced pressure treatment unit; anda container having walls forming a chamber within the container, a proximal end including an opening to the chamber adapted to be fluidly coupled to the inlet and outlet of the support member such that the chamber receives the reduced pressure from the reduced pressure treatment unit, a distal end closing the chamber, wherein the walls have a collapsible portion allowing the container to be compressed to a first volume in a collapsed state and stretched to a second volume in an expanded state, the second volume being larger than the first volume, and a fluidic device disposed within the chamber of the container and adapted such that, when the fluidic device is charged with a fluid, the container is maintained in the expanded state while the reduced pressure from the reduced pressure treatment unit is communicated to the chamber. 11. The canister of claim 10, wherein the integral fluidic device comprises a pneumatic pouch and an intake valve extending through the distal end of the container and in fluid communication with the pneumatic pouch. 12. The canister of claim 11, wherein the intake valve is fluidly connected to the reduced pressure unit. 13. The canister of claim 10, wherein the integral fluidic device comprises a bladder having a distal end and a proximal end, an intake valve disposed at the distal end of the bladder, and a hydrophobic filter disposed within an aperture at the proximal end of the bladder. 14. The canister of claim 10, wherein the collapsible portion is corrugated. 15. The canister of claim 10, wherein the walls further comprise a non-collapsible portion. 16. A method for collecting bodily fluid from a tissue site, the method comprising: expanding a container having walls forming a chamber from a first volume to a second volume, the second volume being greater than the first volume;charging a fluidic device disposed within the chamber of the container with a fluid such that, when the fluid device is charged with the fluid, the fluidic device becomes substantially rigid;generating a reduced pressure via a reduced pressure treatment unit; andcommunicating the reduced pressure to the chamber to draw bodily fluid from the tissue site, wherein the volume of the charged fluidic device maintains the chamber substantially at the second volume while the reduced pressure from the reduced pressure treatment unit is communicated to the chamber.
