  • Patent number: 10232077
    Abstract: A process of preparing an adhesive haemostatic product is provided. The process comprises: (a) coating a porous solid substrate with a coating liquid that comprises an electrophilically activated polyoxazoline (EL-POX) and a solvent to produce a coated substrate; and (b) removing the solvent from the coated substrate. The EL-POX comprises at least 2 reactive electrophilic groups. The process enables the application of an EL-POX coating that leaves the pore structure of the substrate largely intact so that the ability of the porous substrate to absorb body fluids, such as blood, remains essentially unaffected. The EL-POX coated haemostatic product obtained by the present process has excellent adhesive properties due to the presence of electrophilic reactive groups that are capable of reacting with e.g. amine groups that are naturally present in tissue, under the formation of covalent bonds.

  • Patent number: 9144289
    Abstract: The present invention relates to a wrinkle-removing apparatus. When the wrinkle removing apparatus of the present invention adopting a vacuum suction system is tightly applied to the shallow wrinkles on a forehead or to deep wrinkles, a vacuum is created by means of the elasticity of the wrinkle-removing apparatus, in order to strongly suck and pull wrinkles outwardly from the skin. Repeated use of the apparatus with the above-described condition enables a substance such as subcutaneous fat or collagen to replace the wrinkles at the back surface of the wrinkled skin when wrinkles are pulled outwardly from the skin, and finally, skin wrinkles are removed even when the apparatus is no longer used.

  • Patent number: 9101352
    Abstract: A kit is provided including a base with an insert which has a plurality of compartments therein. The compartments are in fluid communication with each other. Liquid bleeding control agent is expressed into the base and allowed to flow to each of the compartments, such as through ports and inside slots between adjacent compartments. Pads reside within each of the compartments, which each include a gauze portion and a gel foam portion. The gel foam portion is wetted by the liquid bleeding control agent, which can be expressed from a syringe provided as a portion of the kit and which flows into the compartments for uniform wetting of gel foam portions of each of the pads. Pads are used during a surgical procedure and then returned to vacant compartments, so that a quick check for remaining vacant compartments indicates whether or not any pads have remained within the surgical site.

  • Patent number: 9089457
    Abstract: A bodily fluid absorbent article adapted to absorb bodily fluid over a wide range thereof. An absorbent structure in the bodily fluid absorbent article includes an upper absorbent component and a lower absorbent component. The absorbent structure further includes one of a dispersing surface constituting the upper absorbent component and kept in contact with the lower absorbent component and a dispersing surface constituting the lower absorbent component and kept in contact with the upper absorbent component. Such dispersing surface exhibits a dispersion velocity for bodily fluid higher than those exhibited by the absorbent sections defined immediately above and under this dispersing surface.

  • Patent number: 9072635
    Abstract: An absorbent article is formed by interposing superabsorbent polymer particles between overlapping two sheets. The pad-shaped absorbent article is composed of superabsorbent polymer particles bonded to the sheet with a hot melt adhesive, absorbing areas where the sheets are not bonded and sealing areas where the sheets are bonded together and surrounding the absorbing areas. Opposed two adjacent bonding areas of the absorbing areas have the sealing areas in between and facing edges which has the sealing areas in between. One of the facing edges is defined by a wavy line having crest and trough portions.

  • Patent number: 9066837
    Abstract: An absorbent article with an annular absorbent member. The absorbent article has a liquid-permeable top sheet, a liquid-impermeable back sheet, an annular absorbent member and a second absorbent member. The annular absorbent member is disposed between the top sheet and the back sheet. The annular absorbent member absorbs and retains a liquid passing through the top sheet. The annular absorbent member defines an aperture in a central portion thereof. The second absorbent member is disposed between the annular absorbent member and the back sheet. The second absorbent member has a visible area aligned with a position of the aperture of the annular absorbent member.

  • Patent number: 9056034
    Abstract: In an absorbent part of an absorbent product, super absorbent materials located between two sheets in an absorbent area swell by absorption of moisture of excrement, and spaces extending in a longitudinal direction from an opening, which is formed at a portion of upper absorbent layer facing the crotch region of a wearer, are formed between a non-absorbent area where the super absorbent materials do not exist and the upper absorbent layer and between the non-absorbent area and a lower absorbent layer. In the absorbent product, through the spaces, moisture of excrement in the second excretion and later can be quickly diffused over a wide area along the longitudinal direction of the absorbent part, and the moisture of excrement can be absorbed in a wide area of the absorbent part. As a result, it is possible to maintain high absorbing ability in multiple excretions in the absorbent product.

  • Patent number: 8986474
    Abstract: 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.

  • Patent number: 8969652
    Abstract: A sanitary napkin is disclosed as a form of disposable absorbent article. It has an absorbent core and a hydrophobic topsheet that has an upper side that is to be worn against a user's body. The topsheet is selected from a group of nonwoven topsheets and apertured film topsheets. A trace amount of a fibrous superabsorbent material, in the range of 0.30 and 3.5 grams of superabsorbent material per square meter, is provided in a fibrous matrix in a secondary topsheet that is in intimate contact with the lower side of the topsheet. The fibrous matrix is made by airlaying the superabsorbent material with cellulose and bi-component fiber onto a non-woven carrier.
