Collagen Or Gelling Material Patents (Class 604/368)
  • Patent number: 7741454
    Abstract: The crosslinking agents and condensing agents that have been employed in biological adhesives and in treating medical devices such as cardiac valves are non-natural compounds synthesized artificially. Thus, they are not metabolized in vivo and exhibit toxicity to living bodies. These compounds are thus used only in a restricted amount and for limited purposes in the clinical sites. The present invention provides a biological low-molecular-weight derivative obtained by modifying carboxyl groups of a biological low-molecular-weight compound with N-hydroxysuccinimide, N-hydroxysulfosuccinimide, or a derivative thereof and a crosslinked high-molecular-weight product obtained by crosslinking various high-molecular-weight compounds with this derivative.

    Abstract: Medical articles including an absorbent layer, a backing layer and an optional liquid permeable facing layer are disclosed. The construction of the medical article is such that volumetric expansion of the absorbent layer is allowed in directions parallel to the surface of the backing layer as the absorbent layer absorbs moisture. The medical article may include a debonding agent located between the absorbent layer and the backing layer. The absorbent layer is operably attached to the backing layer. When the absorbent layer absorbs moisture, e.g., wound exudate, at least a portion of the absorbent layer detaches from the backing layer such that the absorbent layer can expand and move relative to the backing. The debonding agent facilitates this change from attachment to detachment of the absorbent layer to the backing.

    Abstract: The present invention relates to absorbent cores for absorbent articles, which are intended to receive and retain bodily discharges such as urine. Such articles are disposable hygiene articles like baby diapers, training pants, adult incontinence articles, feminine care articles and the like. The improvement essentially is based on the recognition that replacing most or all of the cushioning fibrous absorbent material in an absorbent core by a liquid storage material capable of retaining liquid while maintaining or improving acquisition behavior is desirable as the reduction in cushioning is more than compensated by the gain in comfort. The comfort however can only be achieved if the more fundamental requirements of a diaper in respect to liquid handling are satisfied or improved.

  • Patent number: 7411110
    Abstract: A thin, flexible, high capacity absorbent pad and a method of making such absorbent pads. The absorbent pad contains high levels of superabsorbent material homogeneously mixed with cellulose pulp fluff. The absorbent pad is subjected to high density compaction to achieve the thinness and high absorbent capacity of the invention. The absorbent pad can be used in absorbent articles, such as diapers, training pants, feminine hygiene products, incontinence products, and swim wear.

  • Patent number: 7405341
    Abstract: The present invention relates to absorbent articles comprising superabsorbent polymer particles. The superabsorbent polymer particles are coated with cationic polymers having 1 to 25 mol/kg, referring to the total weight of the cationic polymers, of cationic groups, which can be protonated. The cationic polymers are not substantially covalently bound to the superabsorbent polymer particles. Furthermore, the superabsorbent polymer particles are not substantially covalently surface cross-linked.
