Systems and methods for making hydrophilic foams

Provided herein are methods for making foam materials and foam material products having a polyurethane foam matrix defining a plurality of pores, a hydrophilic agent retained within at least a portion of the pores for improving an absorption of the foam material, a salt retained within at least a portion of the pores in an amount sufficient to render the foam material isotonic, a surfactant retained within at least a portion of the pores in an amount sufficient to be released upon contact with a moist surface. Also provided herein are methods for making a multilayer foam by casting a second foam layer on a first foam layer substrate and compressing the second foam layer before the second layer is fully cured to form an interface layer in situ.

BRIDGE DRESSING WITH FLUID MANAGEMENT

An evaporative bridge dressing that may be used with negative-pressure treatment of tissue. The evaporative bridge dressing may have one or more fluid transfer layers comprised of high-density wicking material enclosed between layers of film having high moisture-vapor transfer rates to manage liquid storage and pressure drop. The evaporative bridge may have an absorbent in some embodiments. An evaporation channel may be disposed adjacent to or combined with the evaporative bridge. A means for measuring pressure across the evaporative bridge may include a feedback path. A support means may reduce or prevent collapse of one or more of the evaporative bridge, the evaporation channel, the feedback path.

MOISTURIZING FACILITATING FOOT COVERING ASSEMBLY
20230292850 · 2023-09-21 ·

A moisturizing facilitating foot covering assembly includes a sleeve of cloth material to be positioned on and cover a person's foot. The sleeve includes a bottom wall and a perimeter wall that is attached to and extends upwardly from the bottom wall. The perimeter wall includes a heel end, a toe end, a first lateral edge and a second lateral edge. A top wall is attached to the perimeter wall. The top wall has a foot opening therein positioned adjacent to the heel end. The cloth material is air and fluid permeable. A coating is positioned on an interior surface of the sleeve. The coating is flexible as well as air and fluid impermeable. The top wall is free of the coating. The coating prevents the sleeve from absorbing any moisturization composition positioned on a lower surface of the person's foot.

Breathable interface system for topical reduced pressure

A reduced pressure tissue treatment system includes an applicator having an aperture, a first pad section, and a second pad section substantially covering the aperture and positioned substantially adjacent the first pad section. A fabric layer is located at least partially between the second pad section and the drape, and the fabric layer includes a woven or non-woven fabric made from a fiber material. A drape substantially covers the first pad section, the second pad section, the fabric layer, and the applicator. A reduced pressure source is in fluid communication with at least one of the first pad section and the fabric layer for providing reduced pressure to the aperture.
