The present disclosure is directed to techniques for coupling activation of sensor devices with use of authorized products. A system includes a sensor device. The sensor device includes a housing that attaches to an absorbent article configured to absorb and contain bodily exudates. The sensor device further includes at least one sensor formed on or within the housing configured to capture sensor data in association with wear of the absorbent article. The system also includes a processor that executes computer executable components. The computer executable components include a communication component that receives an activation code and an activation component that activates a functionality based on the receipt of the activation code.

Disclosed herein are fluff pulp compositions, absorbent articles comprising the fluff pulp compositions, and related methods. The fluff pulp compositions comprise a chemiluminescent system configured to produce visible light upon contact with an aqueous system. Representative absorbent articles include disposable diapers and adult incontinence products. Representative chemiluminescent systems include bioluminescent systems.

The present disclosure provides an absorbent article for personal hygiene. More particularly, in one embodiment, the absorbent article absorbent article includes at least one property changing indicator. A detector device is also provided that includes at least one sensor. The sensor is adapted to detect the property change of the property change indicator in the absorbent article. In one particular embodiment, for example, the property changing indicator may include an optical property indicator such as a color change indicator and the sensor may include an optical sensor such as a color sensor.

The invention provides an absorbent article comprising an indication means for indicating the presence of bodily exudates, the indication means comprising a color-changing indication means, wherein the absorbent article and the indication means form one integral unit, the article further comprising a indication device, which comprises a housing and a connection means, such that the indication device can be attached to the absorbent article and be detached from the absorbent article, wherein the indication device comprises a color sensor.

A system includes an absorbent article that absorbs and contains bodily exudates and comprises an indication unit that generates an optical signal indicative of presence of the bodily exudates within the absorbent article. The indication unit comprises an optical property changing element that changes from having a first optical property to having a second optical property in response to exposure to the bodily exudates. The indication unit further comprises a visual modifying element proximate that provides a visual modification to the second optical property, resulting in the optical signal comprising a third optical property, wherein a sensor device that attaches to the absorbent article detects the presence of the bodily exudates based on recognition of the optical signal comprising the third optical property.

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 sensor for monitoring wetness in a diaper or other absorbent article includes a housing that attaches to the absorbent article. The sensor may include inner and outer housing portions that capture an edge of the absorbent article between the housings. The sensor may include contacts that electrically connect with a pair of contact strips embedded in the absorbent article. The distance between the embedded strips may vary depending on the size of the absorbent article. The sensor may include multiple pairs of contacts that are spaced apart to match the distance between the contact strips for the variously sized absorbent articles. In this way, depending on the pair of contacts connected to the contact strips, the sensor may indicate the size of the absorbent article. The sensor may have a housing with a cavity and a lid that closes the cavity. The lid may be secured with a latch.

The present invention relates to a wound healing PVA sponge dressing using negative capillary pressure of the dressing material together with auxiliary negative pressure for wound treatment. The PVA sponge dressing is pretreated with gram positive and gram negative biocidal 5 dyes for insertion into or over a wound. A negative pressure pump is mounted to the PVA sponge dressing to produce additional capillary pressure for withdrawing fluid or water vapor from the sponge dressing and a cover is mounted over the sponge material and negative pressure pump forming a unitary sealed package for placement over a wound.

The present invention relates to a sponge dressing for treating wounds comprised of a polymer sponge containing a plurality of antimicrobial dyes with at least one dye being gram positive and at least one other dye being gram negative and a silicon adhesive secured to a sponge surface. The sponge dressing can be exposed initially to gamma radiation and later sterilized by ethylene oxide or alternatively it can be sterilized by ethylene oxide and later irradiated by gamma radiation. The sponge dressing has a morphology characterized by an average pore throat diameter of 0.5-500 μm and a porosity ranging from about 60% to about 99.5%. The sponge dressing can also contain at least one biofilm reducing agent, at least one chelating agent and an ionic and non-ionic surfactant.
