Given grinding, mixing and melting steps, the materials using a supercritical fluid as a foaming agent can be used to manufacture the degradable hemostatic sponge having an open-cell microcellular form by a continuous extrusion foaming process. In addition, the present invention also includes a system and a method for manufacturing the degradable hemostatic sponge.

  • Publication number: 20120053546
    Abstract: A feminine cooling pad is configured for use in cooling a woman's vulva and/or adjacent region. The cooling pad may be configured for single use and be disposable so as to include a liquid permeable layer configured to be oriented toward a user's skin during use. A liquid absorbent layer is adjacent to the liquid permeable layer and configured to absorb bodily fluids or discharges during use. A cooling layer is adjacent to the liquid absorbent layer and configured to provide a cooling effect for a period of time of at least about 15 minutes when the cooling pad is placed against a user's skin. An adhesive layer is adjacent to the cooling layer and adheres the feminine cooling pad to a user's undergarment during use and maintains the cooling pad in a desired orientation relative to the user's body. A feminine heating pad may be provided by including a microwavable material that becomes warm or hot when placed in a microwave oven.

  • Patent number: 8063266
    Abstract: A process for producing thin absorbent planar structures which may be used in hygiene products such as diapers, incontinence products, wound contact materials or sanitary napkins to absorb body fluids, comprises the steps of: A) producing a mixture of an adhesive in dispersion form and a particulate absorbent by fluidizing the components, B) applying the mixture of adhesive and absorbent uniformly to the surface of one side of a first planar backing material, C) one side of a second planar backing material is applied to the mixture of adhesive and absorbent that is present on the surface of one side of the first planar backing material, so producing a sandwichlike intermediate, and D) the sandwichlike intermediate is processed to the end product at a temperature of at least 90° C., a pressure of from 4 to 50 bar, and a pressing time of from 0.5 to 5 min.
