Negative pressure wound treatment apparatuses and methods with integrated electronics

A wound dressing apparatus comprising:

• a wound dressing comprising:
• an absorbent material;
• an electronics unit comprising a negative pressure source, the electronics unit integrated within the wound dressing and at least partially encapsulated by a flexible film,
• wherein the flexible film comprises a window comprising a porous material;
• and
• wherein the window is configured to permit fluid communication between the absorbent material and the negative pressure source.

A wound dressing apparatus comprising:

• a wound contact layer comprising a proximal wound-facing face and a distal face, wherein the proximal wound-facing face is configured to be positioned in contact with a wound;
• at least one absorbent layer over the wound contact layer;
• a cover layer configured to cover and form a seal over the wound contact layer and the at least one absorbent layer;
• and
• an electronics assembly comprising:
• an electronics unit comprising a negative pressure source and an inlet protection mechanism configured to prevent wound exudate from entering the negative pressure source;
• a housing comprising:
• a plate;
• and
• a flexible film comprising an aperture;
• wherein the electronics unit is enclosed within the flexible film and the plate;
• and
• wherein the inlet protection mechanism is sealed to the aperture in the flexible film;
• wherein the at least one absorbent layer and the cover layer comprise recesses configured to receive the electronics assembly and the at least one absorbent layer is configured to be in fluid communication with the inlet protection mechanism of the electronics unit.
