Appurtenances to a wound dressing and systems for monitoring wound dressings are described. In some embodiments, a system for monitoring a wound dressing includes: an appurtenance to a wound dressing, wherein the appurtenance includes a sensor unit, an electronic identifier, and a transmitter unit operably attached to the sensor unit and to the electronic identifier; and a local unit including a receiver for the transmitter unit, a processor operably attached to the receiver, and a communication unit operably attached to the processor.

Wound dressing monitoring systems including appurtenances for wound dressings

Appurtenances to cavity wound medical dressings are described. In some embodiments, an appurtenance to a cavity wound dressing includes: a substrate including at least one wound-facing surface, the wound-facing surface configured to be oriented facing a wound surface of a cavity wound; and a plurality of sensor units attached to the substrate, the plurality of sensor units oriented and positioned on the substrate relative to the wound surface of the cavity wound.

Appurtenances to cavity wound dressings

Appurtenances to wound dressings are described, which include: a substrate configured to mechanically or chemically attach to a wound dressing; a transmission unit attached to a surface of the substrate, the transmission unit including circuitry and at least one antenna, the transmission unit configured to transmit a signal; and a projection operably attached to the transmission unit, the projection of a size and shape to extend into an interior region of the wound dressing and configured to sample a fluid associated with a wound.

Appurtenances for reporting information regarding wound dressings

In some embodiments, an appurtenance to a wound dressing includes: a substrate with at least one surface of a size and shape to mate with a surface of a wound dressing; a plurality of projections attached to the substrate and positioned to secure the substrate to the wound dressing; one or more sensor units attached to the substrate, the one or more sensor units configured to sense a condition of the wound dressing; and a transmission unit attached to the substrate and operably coupled to the one or more sensor units, the transmission unit including circuitry configured to transmit information associated with the one or more sensor units.

Appurtenances including sensors for reporting information regarding wound dressings

Appurtenances to wound dressings can include: a substrate configured to attach to a wound dressing; a fluid-activated voltaic cell attached to the substrate; a transmission unit attached to a surface of the substrate, the transmission unit including circuitry and at least one antenna, the transmission unit configured to transmit a signal in response to current generated by the fluid-activated voltaic cell; and a projection operably attached to the fluid-activated voltaic cell, the projection of a size and shape to extend into an interior region of the wound dressing and configured to sample a fluid within the interior region of the wound dressing.

Dormant to active appurtenances for reporting information regarding wound dressings

Computational systems and methods for reporting information regarding appurtenances to wound dressings are described. A system can include an appurtenance to a wound dressing, including a substrate, a transmission unit, a selectively activated switch, and a projection of a size and shape to extend into an interior region of a wound dressing and configured to sample a fluid associated with a wound; a local unit, including a receiver configured to receive signals from the transmission unit, a transmitter configured to send signals to the transmission unit, a processor, non-volatile memory, and a power source; and a central assembly, including a processor, a receiver configured to receive signals from the local unit, and at least one user interface.
