REDUCED-PRESSURE, MULTI-ORIENTATION, LIQUID-COLLECTION CANISTER
First Claim
1. A reduced pressure treatment system for applying reduced pressure treatment to a tissue site, the system comprising:
- a reduced pressure source; and
a liquid-collection canister comprising;
a canister housing defining a first space configured to collect liquid from the tissue site;
a canister outlet configured to allow fluid communication between the reduced pressure source and the first space;
a liquid-air separator disposed adjacent the canister outlet to prevent the liquid from exiting the first space through the canister outlet;
an elongated member connected to the liquid-air separator and extending away from the liquid-air separator into the first space, the elongated member having a wall defining a second space, at least a portion of the wall allowing gaseous communication between the first space and the second space; and
a biasing member disposed in the second space to reduce collapse of the membrane into the second space when the second space is exposed to reduced pressure.

Abstract
An apparatus for use in a multi-orientation liquid collection canister to collect liquid from a tissue site is provided. The apparatus includes a substantially planar, liquid-air separator disposed on at least one wall of the multi-orientation liquid collection canister to prevent the liquid from exiting the multi-orientation liquid collection canister. The apparatus further includes an elongated member connected to the liquid-air separator and extending away from the liquid-air separator into a first space of the multi-orientation liquid collection canister. The elongated member has a membrane defining a second space along at least a portion of a length of the elongated member. At least a portion of the membrane allows gaseous communication between the first space and the second space.

26. A reduced pressure treatment system for applying reduced pressure treatment to a tissue site, the system comprising:
-
a reduced pressure source; a liquid-collection canister comprising; a chamber configured to collect liquid from the tissue site; a canister outlet in fluid communication with the reduced pressure source; and a flexible member having a gas communication pathway at least partially defined by a flexible wall, the flexible member being positioned in the chamber such that the gas communication pathway is in fluid communication with the canister outlet, at least a portion of the flexible wall being gas permeable and substantially liquid impermeable.

55. A reduced pressure treatment system for applying reduced pressure treatment to a tissue site, the system comprising:
-
a reduced pressure source; and a liquid-collection canister comprising; at least one canister wall defining a chamber configured to collect liquid from the tissue site; a canister outlet in fluid communication with the reduced pressure source; a conduit positioned in the chamber, the conduit having a conduit wall forming a gas communication lumen, the gas-communication lumen being fluidly connected to the canister outlet; and a liquid-air separator operably associated with the conduit to allow gas communication but to substantially prevent liquid communication between the chamber and the gas-communication lumen.
