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.
