Claim Text:
1. A method of monitoring an appurtenance on a wound dressing, comprising: transmitting a first signal configured to be received by the appurtenance on the wound dressing, the appurtenance including a region extending into an interior region of the wound dressing at a selected depth which samples a fluid associated with a wound; receiving a first appurtenance signal from the appurtenance, the first appurtenance signal from the appurtenance modulated by the fluid contacting an antenna of the appurtenance when a moisture level of the wound dressing is at a level sufficient to cause the fluid to contact the antenna, wherein the first appurtenance signal includes information related to the wound or wound dressing; associating a first time point with the receipt of the first appurtenance signal from the appurtenance; transmitting a second signal configured to be received by the appurtenance; receiving a second appurtenance signal from the appurtenance, the second appurtenance signal from the appurtenance modulated by the fluid contacting the antenna of the appurtenance when the moisture level of the wound dressing is at the level sufficient to cause the fluid to contact the antenna, wherein the second appurtenance signal includes information related to the wound or wound dressing; associating a second time point with the receipt of the second appurtenance signal; comparing the second appurtenance signal from the appurtenance with the first appurtenance signal from the appurtenance to form a signal comparison; comparing the signal comparison with a preset table; and activating an indicator in accord with the preset table.
