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.

22. An apparatus for treating a wound, which comprises:
-
a wound dressing member dimensioned for positioning adjacent a wound bed; and a subatmospheric pressure mechanism including; a subatmospheric pressure generator supported by the wound dressing member, the subatmospheric pressure generator adapted to generate subatmospheric pressure at predefined therapeutic levels and to supply the subatmospheric pressure adjacent the wound bed to facilitate healing; an electronic controller for controlling operation of the subatmospheric pressure generator; and a pressure sensor adapted to detect pressure at a predetermined location relative to the wound dressing member, and send a corresponding signal to the controller. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 44)
