    Abstract: A negative pressure wound therapy device includes a piezoelectric pump, a state detector configured to detect a state of the pump, and a control circuit configured to transmit a first control signal for a first period having a first RMS voltage greater than or equal to a threshold voltage at which driving the pump for a second period greater than the first period can cause the pump to emit sound at a magnitude greater than a sound threshold; receive a first indication of the state; determine if the pump is in a leak condition; transmit, responsive to the pump not being in the leak condition, a second control signal having a second RMS voltage less than the first RMS voltage; and transmit, responsive to the pump being in the leak condition, a third control signal having a third RMS voltage greater than the second RMS voltage.

    Abstract: The illustrative embodiments described herein are directed to systems, methods, and apparatuses for applying a reduced pressure to a subcutaneous tissue site. In one instance, a manifold for applying reduced pressure to a subcutaneous tissue site includes a plurality of first conduits, each of the plurality of first conduits having a wall with at least one first aperture and at least one second aperture. At least one of the plurality of first conduits is operable to deliver reduced pressure to the subcutaneous tissue site. The plurality of first conduits is coupled in a spaced arrangement that forms an interior space. The manifold further includes a second conduit comprising the interior space and formed by a portion of each wall of the plurality of first conduits. The second conduit is in fluid communication with the plurality of first conduits via the at least one second aperture.
