| 1. A wound dressing apparatus, which comprises:
a wound dressing member including a cover member dimensioned for positioning over a wound bed; and
a micropump system including:
a micropump for applying subatmospheric pressure to at least the wound dressing member to facilitate removal of fluid from
the wound bed, the micropump being disposed beneath the cover member adjacent the wound bed;
a pressure sensor adapted to detect pressure at a predetermined location relative to a wound dressing member, and send a corresponding
signal to the control means said the control means include a motor controller adapted to control or vary the output of the
micropump in response to the pressure sensed by the pressure sensor.
