An absorbent article for personal hygiene such as a diaper, or training pant, or incontinence insert, the absorbent article comprising: a liquid permeable topsheet; a liquid impermeable backsheet; an absorbent core positioned between said topsheet and backsheet, an indicator for indicating the presence of exudates and being positioned on a body-facing side of said backsheet, the indicator comprising an electrically conductive material, the article further comprising a detection device that can be removably attached to the absorbent article such to become in electrical communication with said indicator when attached to said article to measure a change in resistance or capacitance in response to a voiding event, wherein the absorbent core comprises a core wrap enclosing absorbent material therein and wherein a top layer of the core wrap is joined to a bottom layer of the core wrap to form one or more channels substantially free of absorbent material, and wherein the indicator (60) comprises a pattern that overlaps with said channels (500) such that said indicator (60) substantially matches the shape of said channels (500).

An absorbent article for personal hygiene such as a diaper, or training pant, or incontinence insert, the absorbent article comprising: a liquid permeable topsheet; a liquid impermeable backsheet; an absorbent core positioned between said topsheet and backsheet; an indicator for indicating the presence of exudates and being positioned on a body-facing side of said backsheet, the indicator comprising a color-changing indicator; the article further comprising a detection device that can be removably attached to the absorbent article, wherein the detection device comprises an optical sensor and when attached to the absorbent article is positioned to overlap at least a portion of said indicator at a detection device position at the front of the absorbent article, and wherein the absorbent core comprises a core wrap enclosing absorbent material therein and wherein a top layer of the core wrap is joined to a bottom layer of the core wrap to form one or more channels substantially free of absorbent material, and wherein the indicator extends between at least portions of said channel(s) along the Y axis and is arranged such that it prolongs beyond the channel(s) at a first distance D1 towards front edge.

A patient support apparatus includes a frame and a mattress supported by the frame and arranged to support a patient thereon. A sensor is included to detect moisture on the patient and/or the patient support apparatus. The sensor produces signals indicative of the presence of moisture on the patient support apparatus. One or more alerts are output in response to the signals provided by the sensor to notify a caregiver of the presence of moisture on the patient support apparatus.

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.

A garment-mountable physiological parameter detector, comprising: an illuminator configured to illuminate in the direction of the garment; a photoresistor configured to receive light reflections from the garment; and an electronic circuit configured to detect a bodily secretion by monitoring the light reflections received by said photoresistor and identifying a temporal pattern being characteristic of a bodily secretion event.

A moisture-sensitive device is provided that includes a fluid-sensitive battery. Exposure of the battery to urine or some other fluid causes the battery to provide a voltage that can be used to power a transmitter. The transmitter can then provide a wireless transmission indicative of the battery having been exposed to the fluid. This moisture-sensitive device can be provided in a diaper and transmissions produced by the device can be detected using a smart phone or other device and used to indicate to a user that the diaper has been soiled. By powering the transmitter using the fluid-sensitive battery and storing the battery in a dry state, such a device can be stored for a protracted period of time before use.

A moisture-sensitive device is provided that includes a dissolvable conductive material. Exposure of the dissolvable conductive material to urine or some other fluid causes the dissolvable conductive material to dissolve, increasing an effective resistance of the dissolvable conductive material. This change in resistance can be detected to determine the presence of an aqueous fluid. In response to such detection, a transmitter can then provide a wireless transmission indicative of the presence of the fluid. This moisture-sensitive device can be provided in a diaper and transmissions produced by the device can be detected using a smart phone or other device and used to indicate to a user that the diaper has been soiled.

Systems and methods for detecting determining a volume of urine in an absorbent article such as a diaper. A diaper loading application obtains a first measurement of ambient light received from a photodetector while a light source is off and a second measurement from the photodetector while the light source is transmitting light on an absorbent article. The application determines a normalized measurement of light reflected from an absorbent article by removing an ambient light signal from the second measurement based on the first measurement. The application determines, from the normalized measurement, a presence of urine in the absorbent article. The application further determines an estimated volume of urine in the absorbent article, wherein the determining is based on an elapsed time since the presence of urine and an activity state of an infant wearing the absorbent article.

Most current incontinence detection systems are expensive, difficult to use, uncomfortable to wear, or suffer limitations in the scope of detected events. However, the present invention features an incontinence detection system that uses inexpensive technologies and is disposable. The system can indicate the degree and persistence of wetness. The degree of wetness can be measured across various factors, including geometrical coverage via multiple independent detection points, each comprising a “detection cell.” A suitably networked system can determine the time and location of wetness. Each cell might be tuned for various factors such as material fluid affinity and exposure area. An advantage of the invention is the ease with which it can be adapted to distinguish fecal incontinence as distinct from urinary incontinence; both forms of incontinence can be monitored using the same system described herein. Another advantage includes the ability to estimate urine salinity.
