Abstract
Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound contact layer, an absorbent layer over the wound contact layer, the absorbent layer comprising one or more apertures, a cover layer configured to cover and form a seal over the wound contact layer and the absorbent layer, and an electronics assembly comprising a negative pressure source. The cover layer can be configured to be compressed within the aperture in the absorbent layer when negative pressure is applied to the wound dressing apparatus and indicate a level of negative pressure below the cover layer. In some embodiments, the wound dressing apparatus can comprise an indicator material layer configured to protrude when negative pressure is applied to the wound dressing apparatus and indicate a level of negative pressure below the cover layer.
