Abstract
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.
Claims17
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.
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, 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 is adapted to charge with a fluid whereby the container is maintained in an expanded state.
A method for collecting bodily fluid from a tissue site, the method comprising:
- expanding a canister from a first volume to a second volume, the second volume being greater than the first volume;
- affixing the expanded canister to a carrier plate;
- and
- creating a reduced pressure within the canister to draw bodily fluid from the tissue site.
A method for collecting bodily fluid from a tissue site, the method comprising:
- expanding a canister from a first volume to a second volume, the second volume being greater than the first volume;
- charging a fluidic device disposed within the canister with a fluid whereby the fluidic device becomes substantially rigid and whereby the canister volume is maintained substantially at the second volume;
- and
- creating a reduced pressure within the canister to draw bodily fluid from the tissue site.
