Dormant to active appurtenances for reporting information regarding wound dressings

摘要

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.

主权项

1. An appurtenance to a wound dressing, comprising:
a substrate configured to attach to a wound dressing; a fluid-activated voltaic cell attached to the substrate, the fluid-activated voltaic cell including an internal region having at least two electrodes, the internal region of the fluid-activated cell being configured to receive a fluid from an interior region of the wound dressing, the fluid-activated voltaic cell being further configured to generate electrical power from interaction of the fluid with the at least two electrodes; 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 the electrical power 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 the interior region of the wound dressing and configured to channel the fluid from within the interior region of the wound dressing to the internal region of the fluid-activated voltaic cell.
