A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within or above 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 a cumbersome 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.

Un appareil de pansement de plaies favorise la cicatrisation d'une plaie grâce à l'utilisation d'un système de micropompe monté à l'intérieur ou au-dessus d'un élément de pansement de plaies. Le système de micropompe comprend une pompe miniaturisée qui applique une pression subatmosphérique à la plaie pour évacuer efficacement le fluide ou l'exsudat du lit de plaie, sans que l'on doive utiliser une source de vide externe encombrante. De ce fait, le pansement pour plaie et le système de micropompe est portatif, ce qui permet la mobilité du patient qui n'est pas disponible lorsqu'une source de vide externe est utilisée. Il n'est pas nécessaire de restreindre le patient dans ses mouvements pour n'importe quelle période pendant laquelle l'exsudat est évacué de la plaie.
