Claim 0:
1. A wound therapy device comprising:
a battery;
a pump including at least four operating modes, the pump configured to be worn by a user; and
a controller coupled to the pump and configured to transition the pump from operating in a first operating mode to operating in a second operating mode responsive to a pressure of the wound therapy device satisfying a first pressure threshold and to transition the pump from operating in the second operating mode to a third operating mode or a fourth operating mode responsive to a condition being satisfied, wherein
the first operating mode is associated with a first drive voltage that is greater than a second drive voltage associated with the second operating mode,
the third operating mode delivers a first therapeutic amount of pressure from the pump, the first therapeutic amount of pressure being less than a second therapeutic amount of pressure delivered by the pump in the second operating mode,
the fourth operating mode delivers a third therapeutic amount of pressure from the pump, the third therapeutic amount of pressure being less than the second therapeutic amount of pressure delivered by the pump in the second operating mode, the fourth operating mode being activated in response to the condition being satisfied when a battery level of the battery fails to satisfy a battery threshold,
the fourth operating mode is associated with a third drive voltage that is less than the second drive voltage; and
the first therapeutic amount of pressure, the second therapeutic amount of pressure, and the third therapeutic amount of pressure are non-zero amounts of pressure.
