COLLAPSIBLE CANISTER FOR USE WITH REDUCED PRESSURE THERAPY DEVICE

摘要

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.

主权项

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; 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, 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; and a 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.
