Abstract
A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within a wound dressing member. The micropump system includes a miniature pump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed without the need for an external vacuum source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used. The patient does not need to be constrained for any period of time while exudate is being removed from the wound.
