1. A monitor device for a wound dressing system comprising a wound dressing and the monitor device, the wound dressing comprising an absorbent core layer, the monitor device comprising:
a processor configured to apply a processing scheme;
a memory;
a first interface connected to the processor and the memory, the first interface configured for collecting wound data from the wound dressing coupled to the first interface, the wound data comprising first wound data from a first sensor of the wound dressing, second wound data from a second sensor of the wound dressing, and third wound data from a third sensor of the wound dressing; and
a second interface connected to the processor, wherein the second interface comprises an antenna and a wireless transceiver, and wherein the processor is configured to transmit a monitor signal as a wireless monitor signal via the antenna and the wireless transceiver,
wherein to apply the processing scheme comprises:
obtaining parameter data based on the first wound data, the second wound data, and the third wound data; and
mapping the parameter data to an operating state of a plurality of operating states for the wound dressing, wherein the operating state comprises a wetting pattern or wetting distribution of the absorbent core layer and the plurality of operating states are each indicative of a degree of wetting of the absorbent core layer of the wound dressing, including at least a first operating state indicating a first degree of wetting and a second operating state indicating a second degree of wetting,
wherein the monitor device is configured to:
in accordance with a determination that the operating state is the first operating state wherein a first wetting pattern is detected on a distal surface of the absorbent core layer, transmit a first monitor signal comprising monitor data indicative of the first operating state of the wound dressing via the second interface; and
in accordance with a determination that the operating state is the second operating state wherein a second wetting pattern is detected on the distal surface of the absorbent core layer, transmit a second monitor signal comprising monitor data indicative of the second operating state of the wound dressing via the second interface.
