System and method for determining a fill status of a canister of fluid in a reduced pressure treatment system

An apparatus for determining a fill-status of a container of fluid in a tissue treatment system, the apparatus comprising:

• a sensing device configured to sense a reduced pressure in a source conduit;
• a valve configured to release the reduced pressure in the source conduit;
• and
• a processing unit in communication with the sensing device and the valve, the processing unit configured to open the valve and to determine a fill level of the container based on a decay of the reduced pressure after opening the valve.

• a sensing device configured to sense a reduced pressure in a source conduit;
• a valve configured to release the reduced pressure in the source conduit;
• and
• a processing unit in communication with the sensing device and the valve, the processing unit configured to:
• open the valve and measure a decay of the reduced pressure after opening the valve,
• signal a first alarm indicative of a full canister if the reduced pressure decays to a predetermined level over a selected amount of time, and
• signal a second alarm indicative of a blockage if the reduced pressure does not decay to the predetermined level over the selected amount of time.
