1. A wound dressing apparatus comprising:
an electronics unit comprising a negative pressure source and a porous inlet protection material configured to prevent wound exudate from entering the negative pressure source, the porous inlet protection material aligned in the same horizontal plane as an inlet of the negative pressure source, the electronics unit encapsulated by a fluid tight sealed enclosure at least partially comprising a flexible film, the flexible film comprising an aperture, wherein the electronics unit is configured to be incorporated into a wound dressing;
wherein the electronics unit is bonded to the fluid tight sealed enclosure to secure the electronics unit within the enclosure; and
wherein the porous inlet protection material is sealed to the aperture in the flexible film before being incorporated into the wound dressing.
