Abstract

A reduced pressure treatment system includes a processing unit, a reduced pressure source, and a conduit fluidly connected between the reduced pressure source and a tissue site of a patient. The reduced pressure source is configured to operate at a target power level to apply a reduced pressure to the tissue site. A canister is provided to collect fluid drawn from the tissue site. A sensor is provided in communication with the reduced pressure source to determine a source pressure at the reduced pressure source, and an alarm indicator is provided in communication with the processing unit. The processing unit communicates a leak alarm signal or a canister disengaged alarm signal to the alarm indicator when an actual power level of the reduced pressure source exceeds the target power level for a selected period of time.

Claims (20)

1. 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; and an alarm indicator in communication with the processing unit, the processing unit configured to communicate at least one of a leak alarm signal and a canister disengaged alarm signal to the alarm indicator when an actual power level of the reduced pressure source 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.
2. The system according to claim 1, 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; and 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.
3. The system according to claim 2, wherein the first alarm pressure is equal to the second alarm pressure.
4. The system according to claim 1, wherein the alarm indicator generates a leak alarm in response to receiving the leak alarm signal.
5. The system according to claim 1, wherein the alarm indicator generates a canister disengaged alarm in response to receiving the canister disengaged alarm signal.
6. The system according to claim 1, wherein the alarm indicator is a speaker and the alarm is a sound produced by the speaker.
7. The system according to claim 1, wherein the alarm indicator is a visual alarm indicator.
8. The system according to claim 1, wherein the reduced pressure source is a reduced pressure pump.
9. The system according to claim 1, wherein the sensor is a pressure sensor.
10. The system according to claim 1, 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;
the processing unit is configured to communicate the canister disengaged alarm signal when the source pressure determined by the sensor is less than the first alarm pressure;
the alarm indicator generates a leak alarm in response to receiving the leak alarm signal; and the alarm indicator generates a canister disengaged alarm in response to receiving the canister disengaged alarm signal.
11. A method of distinguishing a leak condition from a canister disengagement condition in a reduced pressure treatment system, the method comprising:
monitoring an actual power level of a reduced pressure pump;
monitoring a source pressure of the reduced pressure pump;
comparing the actual power level to a target power level;
comparing the source pressure to a first alarm pressure and a second alarm pressure.

indicating a leak alarm when the actual power level is greater than the target power level and the source pressure is greater than the first alarm pressure; and indicating a canister disengaged alarm when the actual power level is greater than the target power level and the source pressure is less than the second alarm pressure.
12. The method according to claim 11, wherein the first and second alarm pressures are equal.
13. The method according to claim 11, wherein the indicating steps further comprises audibly indicating.
14. The method according to claim 11, wherein the indicating steps further comprises visually indicating.
15. The method according to claim 11, wherein monitoring the source pressure further comprises sensing the source pressure with a pressure sensor.
16. The method according to claim 11, further comprising:
delaying indication of the alarms until the actual power level has exceeded the target power level for a selected period of time.
17. A reduced pressure treatment system comprising:
means for monitoring an actual power level of a reduced pressure pump;
means for monitoring a source pressure of the reduced pressure pump;
means for comparing the actual power level to a target power level;
means for comparing the source pressure to a first alarm pressure and a second alarm pressure;
means for indicating a leak alarm when the actual power level is greater than the target power level and the source pressure is greater than the first alarm pressure; and means for indicating a canister disengaged alarm when the actual power level is greater than the target power level and the source pressure is less than the second alarm pressure.
18. The system according to claim 17, wherein the first and second alarm pressures are equal.
19. The system according to claim 17, wherein the means for indicating further comprise means for audibly indicating.
20. The system according to claim 17, wherein the means for indicating further comprise means for visually indicating.
