In some embodiments, a wound dressing that incorporates a number of sensors or sensors separate from the wound dressing can be utilized in order to monitor characteristics of a wound as it heals or to identify one or more risk factors or conditions that may precipitate a wound. In some implementations, a wound dressing configured to be positioned in contact with a wound includes a substantially flexible substrate supporting one or more sensors. The one or more sensors can include temperature sensors, conductivity sensors, multispectral optical measurements sensors, sensors, pressure sensors, colorimetric sensors, optical sensors, ultraviolet (UV) sensors, or infrared (IR) sensors.

A wound dressing is disclosed. A wound dressing comprises a first adhesive layer, an electrode assembly, a monitor interface and a multiplexer. The first adhesive layer comprises a proximal surface configured for attachment of the wound dressing to a skin surface of a user. The electrode assembly comprises a plurality of electrodes including a first set of first electrodes. The monitor interface is configured to form a mechanical and electrical connection with a monitor device. The monitor interface comprises a coupling part and a plurality of terminals including a first terminal. The multiplexer comprises a number of N input pins and a number of M output pins. The N input pins include a first set of first input pins for connection to first electrodes of the first set of first electrodes, the first set of first pins including a first primary input pin and a first secondary input pin, and the M output pins include a first output pin. The first primary input pin is connected to a first primary electrode of the first set of first electrodes and the first secondary input pin is connected to a first secondary electrode of the first set of first electrodes, and the first output pin is connected to the first terminal of the monitor interface. The multiplexer is configured to connect the first primary input pin to the first output pin in a first multiplexer configuration and to connect the first secondary input pin to the first output pin in a second multiplexer configuration.

A wound sensor comprising at least one electrode (10a, 10b) and a non-adherent porous layer (25) proximate at least part of the electrode.

To offload forces from a tissue site being treated with reduced pressure, an offloading pressure component may be used as part of a reduced-pressure treatment system. A reduced-pressure source of the reduced-pressure treatment system vents positive pressure exhaust into the offloading pressure component to inflate the offloading pressure component. The offloading pressure component disperses forces away from the tissue site. Other devices, methods, and systems are presented.

A Wound Moisture and Assessment System includes a flexible coupon containing one or more electrochemical moisture sensors for measuring a moisture profile of a wound. The coupon is activated by a wireless RF scanner that provides power to the coupon for taking moisture measurements, receives the moisture measurements therefrom, and transmits the measurements to a computing device. The moisture measurements can be represented as a wound moisture map that allows a patient or caregiver to assess the health and healing progress of a wound such as an ulcer.

Systems and methods are provided for sensing fluid in a dressing on a patient and producing an electrical signal. In one instance, a galvanic cell is used as an electronic detection device. The galvanic cell is placed in the dressing and produces voltage when the dressing is substantially saturated. In one instance, the dressing is a reduced-pressure, absorbent dressing. Other systems, methods, and dressings are presented.
