  • Patent number: 11965817
    Abstract: Disclosed is a cell classification method, to be executed by an analyzer, for classifying cells contained in a specimen, including: preparing a first measurement sample by treating a specimen under a first preparation condition; obtaining a first signal from the prepared first measurement sample; classifying, by using the first signal, cells contained in the first measurement sample; preparing a second measurement sample by treating the specimen under a second preparation condition different from the first preparation condition; obtaining a second signal from the prepared second measurement sample; classifying, by using the second signal, cells contained in the second measurement sample; and comparing a result of the cell classification performed by using the first signal and a result of the cell classification performed by using the second signal, with each other, and outputting an analysis result including a number of cells on the basis of a result of the comparison.

  • Patent number: 11357670
    Abstract: An absorbent article including an absorbent main body including an absorbent core; and a pair of leak-proof walls. The pair of leak-proof walls are on respective widthwise side portions of the absorbent main body. Each of the leak-proof walls is capable of standing on a skin side in the thickness direction. The absorbent core includes a low-basis-weight portion in a widthwise central portion. The low-basis-weight portion has a basis weight of the absorbent core smaller than the basis weight in a surrounding portion. A joined part is formed by joining a surface of the skin-side portion and a surface of the non-skin-side portion, the surfaces facing to each other. The joined part is provided inside a distal end of the leak-proof wall and outside the low-basis-weight portion in the width direction. A part of the joined part and a part of the low-basis-weight portion overlap in the longitudinal direction.

  • Patent number: 11318053
    Abstract: An absorbent article includes: an absorbent main body including an absorbent core; and leak-proof walls on respective widthwise side portions of the absorbent main body. Each leak-proof wall is capable of standing on a skin side in the thickness direction, and includes a skin-side portion and a non-skin-side portion. A joined part is formed by joining at least partially facing surfaces of the skin-side and non-skin-side portions.

  • Patent number: 10925778
    Abstract: An absorbent article includes an absorbent main body; a stomach-side member at an end portion on one side of the absorbent main body; and a back-side member at an end portion on another side. The absorbent main body has a pair of leak-proof walls in respective side end portions. Each of the leak-proof walls has a skin-side portion that includes a plurality of elastic members and a non-skin-side portion. The pair of leak-proof walls each have a joining portion in which mutually opposing surfaces of the skin-side portion and the non-skin-side portion are joined, and a non-joining portion above the joining portion. The mutually opposing surfaces are not joined in the non-joining portion. The joining portions are inward, with respect to the width direction, of leading ends of the leak-proof walls. Each of the joining portions is overlapped with the stomach-side member or the back-side member in an up-down direction.

  • Patent number: 10022279
    Abstract: Provided is a disposable urine-absorption pad with which production costs are reduced, and with which a function for inhibiting the occurrence or aggravation of bedsores is imparted by facilitating relative movement of a skin-contact sheet in a back-and-forth direction with respect to a pad main body. This urine-absorption pad includes: an outer surface sheet; an absorption body; an inner surface sheet; a left side sheet; a right side sheet; an overlap sheet; and a low friction member. The overlap sheet is provided to a gluteal region. A right side edge of the overlap sheet is joined to a left side part of the right side sheet. A left side edge of the overlap sheet is joined to a right side part of the left side sheet. The low friction member is provided between the overlap sheet and the inner surface sheet.

  • Patent number: 9387132
    Abstract: A disposable absorbent article includes a chassis and a liquid-absorbent structure. The chassis has an inner sheet lying on a skin-facing side and an outer sheet lying on a garment-facing side. The outer sheet has a first outer sheet and a second outer sheet lying inside the first outer sheet. The second outer sheet is formed on its outer surface with a display area extending in a longitudinal direction. The liquid-absorbent structure is formed with a central void and lateral voids in which core material for a core is not present. The display area can be visually recognized from the garment-facing side through the first outer sheet and from the skin-facing side also through the central void of the liquid-absorbent structure.

  • Publication number: 20140039443
    Abstract: Provided is an absorbent article such as a disposable diaper wherein, when using a configuration that attaches the fastening tapes directly to the outer nonwoven fabric layer without using target tapes, the strength of the outer nonwoven fabric layer can be maintained while the fastening strength of the fastening tapes is maintained even with repeated use. A disposable diaper (1) is provided with an adhesive layer (80) that is formed from an adhesive and glues a barrier sheet (20) to an outer-layer nonwoven fabric layer (40). The adhesive layer (80) has an adhesive-coating pattern such that the orientation of the fibers forming the outer-layer nonwoven fabric layer (40) and the orientation of the resin forming the barrier sheet (20) intersect.
