Patent ID: 7927319

Claim:
A reduced pressure treatment system comprising: a processing unit; a reduced pressure source; a conduit fluidly connected between the reduced pressure source and a tissue site of a patient, the reduced pressure source configured to operate at a target power level to apply a reduced pressure to the tissue site; a canister in fluid communication with the conduit and the reduced pressure source for collecting fluid drawn from the tissue site; a drape configured for positioning over the tissue site to maintain the reduced pressure at the tissue site; a sensor in communication with the reduced pressure source to determine a source pressure at the reduced pressure source; an alarm indicator in communication with the processing unit, the processing unit configured to compare an actual power level of the reduced pressure source to the target power level, the processing unit further configured to communicate at least one of a leak alarm signal and a canister disengaged alarm signal to the alarm indicator when a comparison between the actual power level of the reduced pressure source and the target power level indicates that the actual power level exceeds the target power level for a selected period of time, the alarm indicator configured to generate an alarm in response to receiving the at least one of the leak alarm signal and the canister disengaged alarm signal; wherein the processing unit is configured to communicate the leak alarm signal when the source pressure determined by the sensor is greater than a first alarm pressure; wherein the processing unit is configured to communicate the canister disengaged alarm signal when the source pressure determined by the sensor is less than a second alarm pressure; and wherein the first alarm pressure is equal to the second alarm pressure.
