Abstract
An apparatus for negative-pressure treatment may include an enclosure having a variable volume compressible to a minimum volume, a port and an actuation surface. The apparatus may include a first one-way valve configured to allow fluid ingress to the enclosure, a second one-way valve configured to allow fluid egress from the enclosure, and an actuator configured to apply a compressive force to the actuation surface. The apparatus may further comprise a motor coupled to the actuator to apply and remove the compression force and having an operating parameter indicative of the variable volume. The apparatus may further comprise a controller coupled to the motor and configured to turn on the motor to engage the actuator to alternately apply and remove the compressive force until the enclosure is compressed to the minimum volume and turn off the motor in response to the operating parameter indicating that the chamber is compressed to the minimum volume.
