ABSORBENT DRESSING WITH REMOTE MEASUREMENT OF DRESSING MOISTURE

A system or apparatus including a dressing, a dressing interface, and a humidity sensor may be suitable for use with systems and methods for treating a tissue site. Embodiments of the apparatus are provided for treating a tissue site with reduced pressure provided by a source of reduced pressure. The dressing may include abase layer, a sealing member disposed proximate the base layer to define an enclosure providing a sealed space over the tissue site, and an absorbent member disposed within the enclosure. The dressing interface may comprise a reduced-pressure port configured to be coupled to the source of reduced pressure and a therapy port covered by a hydrophobic filter defining a reduced-pressure pathway between the hydrophobic filter and the source of reduced pressure. The humidity sensor may comprise a sensing portion fluidly coupled to the reduced-pressure pathway and an output for providing a humidity signal that indicates the amount of fluid extracted from the tissue site and stored by the absorbent member. Other dressings, systems, and methods are disclosed.
