A defecation detection apparatus including: a feces/urine receiving member that is placed to face the body of a wearer and that receives discharged feces and urine; a urine suction device that is detachably attached to the feces/urine receiving member and that can sucks urine discharged in the feces/urine receiving member; a temperature sensor that is placed at a defecation position where discharged feces are received in the feces/urine receiving member; and a control section that detects the presence of discharged feces based on a signal remaining after removing a signal that is output from the temperature sensor within a predetermined time after an operation of the urine suction device from a signal that is output from the temperature sensor.

Defecation detection apparatus

An absorbent article for wear inside of another absorbent article, which has a liquid-permeable facing layer that faces the wearer, and a backing layer that faces another absorbent article. The backing layer is formed from a liquid-impermeable sheet and as at least one opening. Alternatively, the backing layer is formed from a liquid-permeable sheet, and an absorbent core is interposed between the liquid-permeable facing layer and the backing layer.

Absorbent article for prevention of sideward leak

There is disclosed an absorbent article including: a surface structure having a liquid-permeable surface sheet located on a liquid-receiving side; a back sheet; and an absorbent core sandwiched between the surface structure and the back sheet. In an area including at least a centerline extending in a longitudinal direction of the absorbent article, the surface sheet is corrugated to form recesses and ridges extending in the longitudinal direction and alternating with each other in a transverse direction perpendicular to the longitudinal direction. The ridges are given an elastically shrinking function in the longitudinal direction at least at their crests or vicinities thereof so that the surface structure is formed into a curved shape. The surface structure thus curved can fit the shape of a crotch. Therefore, the liquid is hard to flow in the transverse direction to prevent the leakage.

Absorbent article with surface structure

An absorbent disposable undergarment includes an outer garment, such as pants, in combination with a detachable absorbent pad attached inside thereof. First suspending flaps hang down from an inner side of a stretchable waist-opening peripheral edge of the pants toward a crotch section of the pants. The first suspending flaps are provided with first fastener elements that are disposed remote from the waist opening of the pants. Second suspending flaps extend upwardly from longitudinally opposite ends of the absorbent pad. The second suspending flaps are provided with second fastener elements, that are adapted to mate with the first fastener elements, and are disposed remote from the core of the pad. These second fasteners are releasably engaged with the first fasteners.

Disposable absorbent undergarment

An absorbent article comprising a liquid-permeable top sheet, a back sheet, and an absorbent core interposed between the top sheet and the back sheet, wherein the top sheet rises upwardly from the absorbent core to have a plurality of protrusions, which extend parallel with one another in a longitudinal direction of the absorbent article, and a hydrophilic material is provided within the protrusions so as to form a cushion layer.

Absorbent article having cushion layer

An absorbent article including a laminated piece including a liquid-permeable top sheet, a back sheet and an absorbent core interposed between the top sheet and the back sheet. The region where the absorbent core is present includes a center region extending along a lengthwise direction of the absorbent article and side regions adjacent to the center region in a crosswise direction perpendicular to the lengthwise direction. The bending resistance (stiffness) of the laminated piece in the center region is higher than the bending resistance of the laminated piece in the side regions. The absorbent article can be attached in a stably fitting manner with no ready emergence of twisting or tucked-down wrinkles, when the absorbent article is overlaid on the inner face of an outer wear material.

Absorbent article

A disposable absorbent undergarment such as a diaper includes short pants and a liquid-absorbent pad attached to an inner surface of the short pants. The short pants has a front waist section, a rear waist section, a crotch section interposed therebetween, a waist-opening and a pair of leg-openings. The crotch section, the waist-opening and the leg-openings are elastically stretchable. A circumferential region defined by portions of the front and rear waist sections between the waist opening and upper ends of the leg-openings is also elastically stretchable.

A disposable diaper has front and a rear bodies permanently welded together at a crotch zone along a welding line convexly curved upward. Fasteners are formed along side edges of one of the front and rear bodies to enable the bodies to be releasably attached together to form the basic structure of the diaper. An auxiliary liquid absorbent panel is permanently attached to float above the convexly curved welding line of the crotch zone for greater absorbency.

Disposable diapers

Disposable urine-absorbing pad

A disposable diaper having a pair of cuffs longitudinally extending on the inner surface of the diaper along transversely opposite sides thereof across front and rear sections as well as a crotch section longitudinally interdisposed between these two sections, wherein each cuff has a substantially crescent-shaped elastic sheet bonded in its longitudinally stretched state to the inner surface along its longitudinally opposite ends and an outer arc defined between these ends.

Disposable diaper

An absorbent article including an inner sheet and first and second outer sheets. The first outer sheet is of a fine interstice while the second outer sheet is fluid permeable. Through crepe processing, a great number of recesses are formed on an absorbent crepe sheet having wrinkles as the inner sheet. Highly absorbent polymers are charged in the recesses. Then, the first outer sheet adheres to the face on the opening side of the recesses of the inner sheet, while the second outer sheet adheres to the face of the opposite side of the inner sheet. The second outer sheet is positioned toward the side of fluid absorption. When a fluid is applied on the absorbent article, the fluid passes through the second outer sheet onto the inner sheet and the highly absorbent polymers. Because the crepe wrinkles are elongated and extended when the inner sheet absorbs fluid, the recesses are enlarged.

Absorbent article and method for producing the same

A well-fitting disposable diaper having a front gathering to be applied to the crotch of a wearer. The front gathering is formed by elastic members disposed about a border between a crotch region and a front waist region of the diaper and includes one end portions of first and second thin parts which are disposed in the crotch region and the front waist region, respectively. Because the first thin parts are elongated between the second thin parts in the front gathering, the front gathering can readily shrink to press the crotch of a wearer or a protector against incontinence to be applied thereto.

A folded disposable diaper to be packed in a package while being folded inwardly about two first folding lines extending in a longitudinal direction of the diaper and then folded inwardly about two second folding lines extending in a transverse direction thereof perpendicular to the longitudinal direction. The diaper includes an absorption core having four thin areas and one thick area. The thickness of the diaper at the thin area is equal to or less than one half of the thickness of the diaper at the thick area. The first folding line is positioned outside of the center of the thin area in the transverse direction. Therefore, when the diaper is folded about the first folding lines, each of the thin areas is folded on itself to prevent an increase in the thickness of the folded diaper, while maintaining the absorbency of the absorption core.

Foldable disposable diaper

A disposable diaper has a fastening system comprising tape fasteners and a receiving sheet. The tape fasteners extend outward from transversely opposite side edges of a rear region 6 of the diaper. These tape fasteners are releasably fastened to the receiving sheet intermittently bonded by means of adhesive to an outer surface of a backsheet of the diaper. A color of the adhesive can be seen through the receiving sheet and serves as a positioning indicator when the tape fasteners are fastened to the receiving sheet.
