Patent number: 8986474Abstract: Methods related to forming superabsorbent composite core structures using superabsorbent materials, such as superabsorbent polymers (SAP). In one method superabsorbent material is sprayed simultaneously with an adhesive to form a superabsorbent layer adhered to a first flexible sheet of material. A second flexible sheet of material is applied to the superabsorbent layer to position the superabsorbent layer between the first and second flexible sheets of material. At least one of the first or second flexible sheets of material is liquid permeable to allow liquid to penetrate into the superabsorbent layer from outside the composite product.Type: GrantFiled: December 10, 2012Date of Patent: March 24, 2015Assignee: Nordson CorporationInventors: Hubert Kufner, Ernst Hering

Publication number: 20150080823Abstract: Absorbent articles are described comprising an absorbent composite. The absorbent composite comprises a first absorbent layer comprising a polymeric foam having an average cell size of at least 100 microns. The polymeric foam has at least one property selected from a) an indentation force deflection of less than 75 N at 50%; or b) a constant deflection compression set of less than 25% for a deflection of 50%; or a combination of a) and b); and a second absorbent layer in fluid communication with the fluid transport layer. In another embodiment, the a second absorbent layer has an average absorption capacity of at least 20 g/g. In another embodiment, a polyurethane foam is described having an average cell size of at least 100 microns. The polyurethane foam comprises the reaction product of at least one polyol component having polyethylene oxide units and a polyisocyanate component that comprises at least 75 wt-% of at least one polymeric polyisocyanate that lacks urethane linkages.Type: ApplicationFiled: April 5, 2013Publication date: March 19, 2015Inventors: Delton R.

Publication number: 20150065976Abstract: The present disclosure is directed, in part, to an absorbent article that comprises a liquid management system (LMS) and an absorbent core disposed at least partially intermediate a topsheet and a backsheet. The LMS defines one or more channels substantially free of superabsorbent polymers. The one or more channels of the LMS may at least partially overlap channels defined by the absorbent core. The absorbent article may comprises a liquid distribution system (LDS) that defines one or more channels.Type: ApplicationFiled: August 25, 2014Publication date: March 5, 2015Inventors: Donald Carroll ROE, Kathy Quinlan AMES-OOTEN, Julia BOESEL, Barry Robert FEIST, Nelson Edward GREENING, II, Carsten Heinrich KREUZER, Cornelia Beate MARTYNUS, Marie Brigid O'REILLY, Sandra SAUTTER, Beate SIMON, Lutz STELZIG, Rachael Eden WALTHER

Publication number: 20150065977Abstract: Described are devices useful for providing hemostasis at a vascular access site, and related methods. Such devices can include first and second implant members cooperable when forced together to expand the first implant member in a tissue tract at the site. Such devices can also include an anchor member and a tether attached thereto. The anchor member can be deployed distally to the first implant member, within a vessel, and the tether can be tensioned to apply counterforce to the first implant member as the second implant member is forced into cooperative contact to expand the first implant member.Type: ApplicationFiled: September 4, 2014Publication date: March 5, 2015Inventor: Darin G. Schaeffer

Publication number: 20150032069Abstract: A wound dressing for covering a wound includes a textile layer woven by polyacrylonitrile-based activated carbon fiber, and an absorbent layer provided on one side of the textile layer away from the wound. The activated carbon fiber is produced by polyacrylonitrile oxidized fiber in a moisturized carbon dioxide atmosphere at the temperature of 700° C. to 1200° C. for 1 to 60 minutes. The material of the absorbent layer is cotton, alginate, poly vinyl alcohol, or a combination thereof. The water absorbing ability of the absorbent layer is superior to that of the textile layer. Because the textile layer does not produce dust and can keep dry, the hard-to-heal wounds can be prevented.Type: ApplicationFiled: July 29, 2013Publication date: January 29, 2015Applicant: BIO-MEDICAL CARBON TECHNOLOGY CO., LTD.Inventors: Tse-Hao KO, Ching-Han LIU, Jui-Hsiang LIN, Yen-Ju SU

Publication number: 20150018793Abstract: A sanitary disposable urine device is provided. The device includes an inner ring and outer ring each having a top surface and opposing bottom surface. The outer ring is substantially concentric with the inner ring and may be offset. At least one of the top surfaces of the inner and outer rings conforms to a body contour of a user's perineum. The device further includes a hand holder coupled to the bottom surface of the inner ring, the hand holder having an opening configured to match to the inner ring. The device also includes a fluid containing bag having an open end attached to the hand holder such that fluid flows through the inner ring and the opening of the hand holder into the fluid containing bag during usage. The device also includes an inner bag inside the fluid containing bag for containing an absorbent material and an outer sealable bag to secure the device after use.Type: ApplicationFiled: September 29, 2014Publication date: January 15, 2015Inventors: Roger Huckfeldt, Cindy Lowe, Keela Davis, Martin Reuter, John Price
