An underpad for covering a patient support structure includes an upper, patient facing surface and a lower, support structure facing surface. The underpad includes a liquid permeable patient facing layer and a liquid impermeable base layer. An absorbent layer is positioned above the base layer and below the patient facing layer, and a tissue layer is positioned above the absorbent layer and below the patient facing layer. An ink is deposited on the tissue layer. The ink is more readily visible through the patient facing layer than through the base layer.

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.

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.

To provide a composition for wet indicator excellent in discoloration performance. What is disclosed is a composition for wet indicator comprising an oily gel and a wet-sensitive colorant composition.

To provide a composition for wet indicator which is excellent in discoloration performance and is suppressed in odor. What is disclosed is a composition for wet indicator comprising: a hydrocarbon oil (A), at least one selected from saturated fatty acids having 16 or more carbon atoms and derivatives thereof (B), and a wet-sensitive colorant composition (C), wherein the component (B) is contained in an amount of 2 to 85 parts by mass based on 100 parts by mass of the total amount of the components (A) to (C).

An absorbent article comprising an absorbent core having at least two longitudinally extending channel-forming areas and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid the core wrap forms channels along these areas substantially free of absorbent material. The wetness indicator is placed between the channel-forming areas or between at least one channel-forming area and at least one longitudinally extending side edge of the article, as seen for the exterior of the article.

An absorbent article including an absorbent core arranged between a topsheet and a backsheet, the absorbent article having a longitudinal axis and a transversal axis extending in a perpendicular direction in relation to the longitudinal axis, the absorbent article having a front portion, a back portion and a crotch portion there between, and at least one wetness indicator, wherein at least one first wetness indicator is arranged in the front portion and/or the back portion. Furthermore, the absorbent article includes at least one permanent visual element arranged in the crotch portion, and the permanent visual element mimics the visual appearance of the wetness indicator.

A signal layer for an absorbent article provided to absorb menstrual fluid includes a pattern of capillary channels allowing capillary action such that discharged menstrual fluid that comes across one of the openings in the capillary channels enters into the capillary channels and is retained therein due to the capillary force. The color of the retained menstrual discharge dyes or colors the pattern for signaling purpose, and the pattern is directly or indirectly visible to an observer.
