Systems, methods, and apparatuses are presented that facilitate the provision of reduced pressure to a tissue site by using a delivery-and-fluid-storage bridge, which separates liquids and gases and provides a flow path for reduced pressure. In one instance, a delivery-and-fluid-storage bridge includes a delivery manifold for delivering reduced pressure to a treatment manifold at the tissue site and an absorbent layer proximate the delivery manifold adapted to receive and absorb liquids. The delivery manifold and the absorbent layer are encapsulated in an encapsulating pouch. A first aperture is formed proximate a first longitudinal end of the delivery-and-fluid-storage bridge for fluidly communicating reduced pressure to the delivery manifold from a reduced-pressure source, and a second aperture is formed on a patient-facing side of the delivery-and-fluid-storage bridge. Reduced pressure is transferred to the tissue site via the second aperture. Other systems, apparatuses, and methods are disclosed.

Tissue dressing materials and associated methods of forming such dressing materials are disclosed. In one example embodiment, a dressing material may include a foam and a film formed on a first side of the foam. The film may be integrally-formed on the side of the foam. The film may include a plurality of apertures. A method of making the dressing material may include placing a pre-polymer mixture and water into a mold to create the dressing material comprising a foam and an integral film on at least one surface of the foam. The method may further include forming a plurality of openings in at least the integral film, with the openings being formed within the mold or subsequent to removal of the dressing material from the mold.

A dermal dressing is provided that comprises a foam layer and an adhesive layer applied directly thereon. A textile fabric is arranged on a side of the foam layer facing away from the adhesive layer, and the textile fabric comprises a vertically-lapped nonwoven. A method for producing the dermal dressing of the first aspect is also provided. The method comprises: providing the foam layer; applying the adhesive layer to the foam layer; applying the textile fabric to a side of the foam layer facing away from the adhesive layer; and bonding the foam layer and the textile fabric. The dermal dressing has optimal properties for its use in preventing pressure ulcers.

The present disclosure relates generally to wound dressings that reduce the pressure drop observed during use in negative pressure wound therapy (NPWT). The wound dressings include a first layer and a second layer; wherein each of the first layer and the second layer independently comprise a biopolymer and a plurality of perforations, wherein each perforation comprises a width and an external perimeter, and wherein the first layer and the second layer are adjoined such that the external perimeter of each perforation in the first layer does not overlap or intersect with the external perimeter of each perforation in the second layer.

In some embodiments, an apparatus, system, and method for activating a low-adhesion state of a thermal-sensitive tape is described. An example apparatus embodiment includes a light source and a temperature sensor. The light source is configured to illuminate a target area of the thermal-sensitive tape with a first spectrum of electromagnetic radiation to provide heating of the target area. The first spectrum including a first wavelength outside of a visible spectrum. The temperature sensor is configured to detect a second spectrum of electromagnetic radiation to approximate a temperature of the target area. The second spectrum includes a second wavelength different than the first wavelength.

A medical dressing including: a flexible base layer including a front surface configured to face a skin of a patient and a back surface opposite the front surface, wherein the flexible base layer includes a first opening; an adhesive layer on the front surface of the base layer; a flexible cover layer entirely covering the opening of the base layer; a flexible intermediate layer sandwiched between the base layer and the cover layer, wherein the base layer, cover layer and intermediate layer joined together along an annular pattern extending entirely around the first and second openings, wherein the annular pattern joints the base layer to the intermediate layer entirely around the first and second openings, and the annular pattern joins the layers around the first and second openings except at slots extending beyond an outer edge of the cover layer and ending before an outer edge of the intermediate layer.

Dressing or bandage for protecting a wound accidentally incurred, surgical incision deliberately made in the skin, epidermal delivery of medication, or musculotherapy of a human being or animal, said bandage/dressing having the primary characteristic of being significantly atraumatic upon removal of same by virtue of a novel stringlike member that is intentionally incorporated into or debossed into the construction of said parent bandage/dressing in a multi-spiral geometry, said stringlike member firstly being pulled gently and progressively in multiple turns around the wound site or epidermal treatment area to in effect significantly reduce the area of remaining/undisturbed adhesive between the bandage/dressing and patient's skin before the bandage/dressing is peeled away from the skin in conventional manner and thus affording the patient a significantly less traumatic experience.

Scalable virtual memory metadata management comprising a plurality of pre-instantiated VM metadata containers representing the entire amount of real physical memory available to a computing system, with additional instantiated VM metadata containers created as needed. Individual and/or groups of VM metadata containers are assigned to metadata container groups, wherein each container group is controlled by an acquired lock assigned to the VM metadata container groups. Virtual memory metadata is managed using a “least used” technique. In response to allocation requests, the allocator scans the container groups/VM containers and fulfills memory object metadata allocation to the least used VM metadata container of the least used container group, filling the individual VM metadata containers and/or the container groups at a nearly equal rate.

A dressing for treating a tissue site, particularly a peritoneal or abdominal site, is disclosed. The dressing may comprise: first and second layers, each being made from a liquid-impermeable material and being at least partially fenestrated, the layers being coupled together to define a chamber therebetween; and disposed within the chamber a third layer comprising a manifold having a central region, and a perimeter region containing perforations arranged in a pattern defining a plurality of sub-regions. The first and second layers can be coupled using a plurality of welds or bonds through the perimeter region perforations. Optionally, the manifold does not comprise, and the chamber does not contain, any manifolding elements extending outward from an outer edge of the perimeter region.

A dermatologic treatment apparatus comprising a light emitting part, for emitting light for dermatological treatment. The apparatus further comprises a skin treatment dressing. The skin treatment dressing is a bioactive dressing and is arranged to adhere to a user's skin, during use. The skin treatment dressing is arranged with the light emitting part such that, in use, light from the light emitting part passes to the skin treatment dressing. The skin treatment dressing is configured such that the light from the light emitting part passes through the skin treatment dressing to a user's skin.
