Abstract: A cleansing device for mammalian skin includes a cleansing head having a plurality of elastomeric cleansing features extending away from a first surface of the cleansing head. The cleansing head is attached to a handle. The cleansing device includes an actuator coupled to a rotating drive shaft and adapted to apply oscillating movement to one or more cleansing head sections of the cleansing head at a frequency of about 5 Hz to 30 Hz.

Abstract: Some embodiments disclosed herein are directed to a pump assembly comprising a voice coil, a magnet and a diaphragm, wherein the voice coil is configured to move the diaphragm to pump a fluid through the pump assembly in response to a drive signal applied to the voice coil. Some embodiments disclosed herein are directed to an apparatus for applying negative pressure to a wound comprising a source of negative pressure configured to be coupled to a dressing, the source of negative comprising a voice coil actuator and a diaphragm, and a controller configured to produce a drive signal for the voice coil actuator.
