Abstract
A wound dressing is disclosed, the wound dressing comprising a first adhesive layer with a proximal surface configured for attachment of the wound dressing to the skin surface of a user; an absorbent core layer; an electrode assembly comprising a plurality of electrodes arranged on a distal side of the absorbent core layer, the electrode assembly comprising a plurality of sensor points distributed along a distal surface of the absorbent core layer; and a top layer on a distal side of the electrode assembly.
Claims20
A wound dressing system, comprising:
- a wound dressing, comprising:
- a first adhesive layer configured for attachment of the wound dressing to a skin surface of a user;
- an absorbent core layer;
- an electrode assembly comprising a plurality of electrodes arranged on a distal side of the absorbent core layer, the electrode assembly comprising a plurality of sensor points each configured to sense wetting of the distal surface of the absorbent core layer;
- and
- a monitor interface electrically coupled to the electrode assembly;
- and
- a monitor device, comprising a processor and a first interface for connection to the monitor interface of the wound dressing, wherein the monitor device is configured to:
- obtain wound data from the wound dressing via the first interface;
- determine, based on the wound data, an operating state of the wound dressing, wherein the operating state is indicative of a degree of wetting of the absorbent core layer;
- when the operating state is a default operating state, transmit a default monitor signal indicative of the default operating state of the wound dressing;
- and
- when the operating state is a first operating state, transmit a first monitor signal indicative of the first operating state of the wound dressing, wherein the first monitor signal indicates a different degree of wetting than the default monitor signal.

A monitor device, comprising:
- a processor;
- and
- an interface for connection to a monitor interface of a wound dressing, wherein the monitor device is configured to:
- obtain wound data from the wound dressing via the first interface;
- determine, based on the wound data, an operating state of the wound dressing, wherein the operating state is indicative of a degree of wetting of the wound dressing;
- when the operating state is a default operating state, transmit a default monitor signal indicative of the default operating state of the wound dressing;
- and
- when the operating state is a first operating state, transmit a first monitor signal indicative of the first operating state of the wound dressing, wherein the first monitor signal indicates a different degree of wetting than the default monitor signal.

A monitor device, comprising:
- a processor;
- and
- an interface for connection to a monitor interface of a wound dressing, wherein the monitor device is configured to:
- obtain wound data from the wound dressing via the first interface;
- determine, based on the wound data, an operating state and a wetting pattern of the wound dressing, wherein the operating state is indicative of a degree of wetting of the wound dressing;
- when the operating state is a first operating state, transmit a first monitor signal indicating the first operating state of the wound dressing and including a pattern representation of the wetting pattern;
- and
- when the operating state is a second operating state, transmit a second monitor signal indicating the second operating state of the wound dressing and including the pattern representation of the wetting pattern, wherein the second monitor signal indicates a different degree of wetting than the first monitor signal.
