An indicator reversibly changes between a first state representative of a first fluid status of a wound dressing, to a second state representative of a second fluid status in response to changes in the fluid status of the wound dressing over time. The fluid status may be a fluid level or a fluid absorbency capacity of the wound dressing. The indicator includes an indicator layer on which one or more markings are provided. A top layer of the indicator transitions from being opaque in the first state to being transparent in the second state. The change from the markings being blocked from view in the first state to being visible in the second state occurs in response to a presence of a first amount of fluid in the wound dressing. The transition from the second state to the first state occurs when evaporation decreases the fluid in the wound dressing.

A closed-circuit dressing system for preventing moisture contacting PICC sites is provided. The closed-circuit dressing system include a breathable bag for harboring the PICC line(s) and a dressing film that envelopes the PICC site, wherein a moisture indicator ring provided by the dressing film indicates moisture penetrating a dressing reinforcement along the periphery of the dressing film.

A wound dressing and a monitor device is disclosed, the wound dressing comprising a top layer; 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; and a monitor interface configured for connecting the wound dressing to a monitor device, the monitor interface comprising a plurality of terminals configured to form electrical connections with respective terminals of the monitor device, wherein the wound dressing comprises a flexible element, the flexible element being bendable and/or twistable between a first flexible element end and a second flexible element end, and wherein the monitor interface comprises a coupling part positioned at the first flexible element end.

A dressing apparatus and methods for facilitating healing, the apparatus and methods involving a dressing member, an electromagnetically conductive element mechanically coupled with the dressing member, and a primary RFID device configured to transmit at least one output signal to the electromagnetically conductive element, to receive at least one return signal from the electromagnetically conductive element, and to provide an alert if the at least one return signal has a strength corresponding to at least approximately a threshold amount of fluid present in the dressing member, whereby healing is facilitated.

An absorbent structure, including a sensor system, can sense and measure the level of wetness contained within the absorbent structure as well as sense and measure environmental conditions. The sensor system may include passive RFID sensors or tags, RFID readers, antenna, a tuning module, a processing module, a memory module and a wireless communication module. The absorbent structure may further include two or more sensors, with a first sensor placed in a first area most likely to first be exposed to liquid and a second sensor spaced apart from the first sensor in an area likely to be exposed to liquid only after the absorbent structure has become more saturated.

A dressing having a multilayer assembly in which dressing includes a polyurethane dressing layer that is adhesively secured over a wound or other location on a user's skin. Label strips that can be incorporated into the dressing. The label strips can include text, indicia, logos, or other markings which are applied to the strip prior to or after application of the dressing.

An indicator, wound dressing system, and negative pressure wound treatment kit configured to provide near real-time, dynamic indication of the fluid status (e.g., fill level, fluid absorbency capacity) of an article is described according to various embodiments. The indicator for detecting a fluid status of a wound dressing may include at least (i) a top side comprising PVDF and one or more markings configured to show fluid levels (ii) a bottom side comprising a pattern-printed adhesive, and (iii) a buffer layer, wherein the buffer layer has a top side comprising a polyurethane film and a bottom side comprising a film retention adhesive. Methods of using the indicator, wound dressing system, and kit are also provided herein.

In one example embodiment, a system for stimulating healing of tissue at a wound site is disclosed. The system comprises a dressing including a porous pad and a drape covering the pad at a wound site for maintaining negative pressure at a wound site, a negative- pressure source including a pump and an electric motor to generate a pump pressure for applying to the wound site, and a first pressure sensor for sensing the pump pressure. The system further comprises a controller coupled to the first pressure sensor and electric motor and a regulator coupled to the controller for inducing leakage into the therapeutic environment of the system to maintain a minimum level of fluid flow within the dressing.

The present disclosure provides a method, performed in an accessory device, for communicating a leakage state of an ostomy appliance, wherein the accessory device comprises an interface configured to communicate with one or more devices of an ostomy system, the one or more devices comprising a monitor device, and/or the ostomy appliance configured to be placed on a skin surface of a user. The method comprises obtaining monitor data from the one or more devices, the monitor data being indicative of presence of fluid at a proximal side of a first adhesive layer of the ostomy appliance towards the skin surface; determining a leakage state at the proximal side of the first adhesive layer of the ostomy appliance based on the monitor data, and communicating the leakage state of the ostomy appliance via the interface.

An assembly includes a drape substantially sealable over a wound bed and a trackpad configured to couple a tube to the drape and allow the tube to provide suction to the wound bed. The assembly also includes a vent opening in the drape, a filter coupled to the drape and communicating with the vent opening, a cover coupled to the drape and movable between a first position to cover the vent opening and filter and a second position to uncover the vent opening and the filter, and a fluid indicator coupled to the drape and operable to provide a visual indication that fluid build-up is present in the wound bed.
