Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising an obscuring layer that may hide fluid contained therein. Some embodiments may further comprise one or more viewing windows disposed therethrough so as to enable monitoring or examination of fluids contained therein.

An enhanced adhesive bandage sandwich (FIG. 1) for compressing blood vessels and a kit for assembling said bandage sandwich. A bandage or kit can be used as a medicament, particularly, for use in treating varicose veins. A bandage sandwich or kit can be used to compress veins or arteries. A method to produce said bandage sandwich can include providing a first adhesive bandage layer; applying an elastic body to the first adhesive bandage layer; and applying a second adhesive bandage layer to the first bandage layer. The elastic body of the bandage sandwich can be shaped to follow the contours of veins or arteries to be compressed.

A medical bandage includes a bandage substrate having a portion designated to receive and underlie an arm of a patient as a non-sterile area. A flap attached longitudinally along one edge of the non-sterile area of the bandage substrate is positionable in: (i) an open position for insertion of the arm; and (ii) a closed position over top of the arm of the patient. The flap has an opening that exposes at least a forearm portion as a sterilizable area of the arm of the patient for therapeutic or diagnostic access to a blood vein. An inner adhesive layer is attached to an inner surface of the flap around the opening to releasably adhere to the arm of the patient. An access panel is sized to cover the opening. An outer adhesive layer attached to an outer surface releasably adheres to an outer annular area of the access panel.

Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

The wound dressing described herein includes a backing layer, absorbent layer, and foam layer. The wound dressing also includes one or more visual indicators. The visual indicators are substantially non-visible in their initial, dehydrated state. As the visual indicators absorb fluid they swell and become visible. The visual indicators enable a caregiver to know when the wound dressing has reached, or is about to reach, its fluid capacity.

Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

A nasal cavity bandage dressing and method of use thereof, including a bandage made from a waterproof, antimicrobial, and adhesive material; and a multi-layered, absorbent sterile dressing affixed to the bandage. The bandage affixed with the non-adherent multi-layered absorbent sterile dressing is configured to fit within a nasal cavity.

Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

The disclosed reinforced adhesive substrate includes a transparent, flexible, breathable backing with a reinforcing material having open areas to the substrate. The reinforcing material strengthen the breathable backing while maintaining transparency so that overall the substrate is transparent. A transparent adhesive substrate can allow the underlying surface to be visualized.

A medical dressing comprising a backing layer and a self-supporting substrate. The backing layers form a perimeter around the self supporting substrate and holds the self supporting substrate in place on a wound. The self supporting substrate comprises a valve. The adhesive article forms a sealed environment between the medical article and the surface surrounding the wound such that a negative pressure can be maintained in the sealed environment through the valve.
