A bandage configured to be administered from a continuous roll, comprising: (I) a first layer of flexible webbed material, the first layer including a self-adhesive disposed on a top surface; and (II) a second layer of flexible padded material adhered to the first layer along a longitudinal axis by the self-adhesive, the second layer having a width less than a width of the first layer so that a portion of the self-adhesive is exposed on each longitudinal side of the second layer; wherein the self-adhesive may releasably adhere to a bottom surface of the first layer in a rolled form so that, when unrolled, an adhesive bond is broken free of damaging the first layer; and wherein, when the self-adhesive is bonded to itself and opposing adhesive portions, the resulting peel strength is greater than a peel strength when the self-adhesive is bonded to skin.

A non-invasive tissue oxygenation system for accelerating the healing of damaged tissue and to promote tissue viability is disclosed herein. The system is comprised of a lightweight portable electrochemical oxygen concentrator, a power management system, microprocessors, memory, a pressure sensing system, an optional temperature monitoring system, oxygen flow rate/oxygen partial pressure monitoring and control system, a display screen and key pad navigation controls as a means of providing continuous variably controlled low dosages of oxygen to a wound site and monitoring the healing process. A kink resistant oxygen delivery tubing, whereby the proximal end is removably connected to the device and the distal end with holes or a flexible, flat, oxygen-permeable tape is positioned at or near the wound bed as a means of applying near 100% pure oxygen to the wound site. The distal end of the tube is in communication with the electrochemical oxygen concentrator and wound monitoring system to communicate oxygen partial pressure and, where appropriate, temperature information. A moisture absorbent dressing is positioned over the distal end of the tubing at the wound site and a reduced moisture vapor permeable dressing system is positioned whereby covering the moisture absorbent dressing, distal end of tubing and wound site creating a restricted or occluded airflow enclosure. The restricted airflow enclosure allows the out-of-the-way control and display unit to provide a controlled hyperoxia and hypoxia wound site for accelerated wound healing.

One embodiment of a waterproof bandage for reliably protecting sensitive sites from water intrusion, despite potential flaws in the seal to skin, comprises three major components: the inner bandage, comprising an absorbent layer (1) and a waterproof layer (2); the outer bandage, comprising an absorbent layer (3) and a waterproof layer (4); and an adhesive layer (5) binding the waterproof layer of the inner bandage (2) and the absorbent layer of the outer bandage (3) together. When properly sized, registered and bonded, the outer absorbent layer (3) functions to wick away and to prevent any water that may penetrate the outer waterproof layer (4) from breaching or damaging the inner bandage. The waterproof bandage can be configured in various sizes as a bandage (FIG. 1), or as a sleeve-like cover for a protected site on hands, arms, feet, legs, and other parts of the body (FIGS. 3 and 4).

A wound care device for the treatment of wounds is disclosed by means of atmospheric negative pressure in the wound region, including a wound-covering element that can be attached to the skin of a patient as well as a connection device for the suctioning of fluid media, wherein the wound-covering element includes a window that can be opened, which window is arranged on the wound-covering element by means of a gas-tight closure.

The invention relates to a bandage (10) comprising a flat material web (12) having a first (14) and a second (16) side and a first (18) and a second (20) end spaced apart in the longitudinal direction of the bandage (10), a wound pad (22) on the first side of the flat material web (12), a pressure application means (32) on the second side (16) of the flat material web (12) opposite the wound pad (22), a securing element (24) on the second end (20) of the flat material web (12) for securing the second end (20) of the flat material web (12) on or to itself for a bandage (10) positioned on a carrier.

A wound treatment system includes a housing that defines an oxygen outlet. An oxygen production subsystem is included in the housing and coupled to the oxygen outlet. A control subsystem is coupled to the oxygen production subsystem and configured to receive pressure information that is indicative of a pressure in a restricted airflow enclosure that is coupled to the oxygen outlet. The control subsystem then uses the pressure information to control power provided to the oxygen production subsystem in order to control an oxygen flow that is created by the oxygen production subsystem and provided through the oxygen outlet to the restricted airflow enclosure.

Examples include devices, systems and methods related to advanced wound therapy dressings. Specific examples are optimized for use with mobile continuous diffusion of oxygen therapy systems for the localized delivery of oxygen to damaged and healing tissues. Examples may utilize a conduit to deliver therapeutic fluids, including for example oxygen, where the conduit comprises a plurality of apertures or perforations. Examples may also include a spacer material with a plurality of distribution channels in fluid communication with the conduit.

An adhesive dressing that reduces the leakage of wound exudate from the dressing, comprising an adhesive-coated backing sheet; and an absorbent island adhered to said adhesive-coated backing sheet by said adhesive, having a first end and a second end, wherein the absorption capacity of the absorbent island is higher at the first end than at the second end. The adhesive dressing of the invention provides extended wear time for the dressing when it is applied to wounds.

The subject of the invention is a wound care article for extraction and control of wound fluids, comprising at least one first fluid-absorbing structure (1; 10; 36), which is surrounded by a liquid-permeable, first enclosure (2), and a liquid-permeable, second enclosure (3) comprising two enclosing surfaces (13.1, 13.2). The wound care article is thus characterized in that the first enclosure (2) is covered or supported on at least one of its flat sides (4.1, 4.2) by at least one fluid-absorbing material layer (6.1, 6.2; 6.3), which is arranged (FIG. 1a) between the first enclosure (2) and one of the enclosing surfaces (13.1, 13.2) of the second enclosure (3).
