  • Patent number: 5868724
    Abstract: A non-continuous absorbent core having a plurality of interconnected strands separated by voids. The strands comprises a porous absorbent macrostructure. The porous macrostructure has interconnected absorbent gelling particles that are surface crosslinked with cationic, preferably polymeric, amino-epichlorohydrin adducts. Upon contacting liquids such as water or body exudates (e.g., urine), the absorbent core can absorb the liquids without undesirable planer expansion. The core is useful in absorbent articles such as diapers, adult incontinence pads, and sanitary napkins are disclosed.

  • Patent number: 5863289
    Abstract: An improved device and process of assuring separation of an anticoagulant type fluid from a saline type fluid each of which is utilized in the process and operation of a plasma-pheresis apparatus or the process of collecting donor blood, is disclosed. The improvement includes a cross-spike prevention receptacle which is dimensioned, and installed positionally in reference to a plasmapheresis or blood donor apparatus, to receive an anticoagulant fluid container to which a proper respective supply communication line will connect, and to exclude and not receive a saline fluid container or container holding a similar type of fluid, whose fluid line will not reach and connect to the installed cross-spike prevention receptacle.

  • Patent number: 5743895
    Abstract: The present invention is directed to an improved disposable diaper and method therefor. The disposable diaper achieves significant fluid absorbency through a wadding batt layer consisting solely of a combination of wood pulp and cotton pulp, rather than through a wadding batt layer comprising wood pulp and a superabsorbent polymer. In this fashion, the disposable diaper minimizes skin irritation that may be caused during rewetting when body waste fluids contacting the superabsorbent polymers carry a portion thereof back out through the diapers into contact with the skins of babies or children using the diapers. The disposable diaper also minimizes skin irritation caused when both the exterior portion of a diaper contacts a child's skin or the skin of a person touching the diaper, by the use of an outer and inner surface layer of a soft, cloth-like, non-woven bond material such as polyester.

  • Patent number: 5733274
    Abstract: A disposable absorbent article, such as a sanitary napkin, is disclosed that has components which may separate in the Z-direction with relation to other components of the article when the absorbent article is worn. The sanitary napkin of the present invention comprises a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core positioned between the topsheet and the backsheet, and a relatively shift liquid pervious spacing structure for moving the topsheet away from the core. The spacing structure is generally positioned between the topsheet and the core. The spacing structure has a longitudinal centerline, and opposed lateral sides which may move inwardly toward the longitudinal centerline when the spacing is compressed from the sides. This results in at least a portion of the spacing structure moving the topsheet apart from the absorbent core.
