Re-epithelialization wound dressings and systems
Methods, apparatuses, and systems for promoting re-epithelialization as an aspect of wound healing are presented. A re-epithelialization dressing for use with reduced pressure has a moist tissue-interface layer, a manifold member, and a sealing member. The moist tissue-interface layer has a plurality of apertures. The moist tissue-interface layer is for disposing adjacent to the wound and provides a moisture balance (i.e., provides moisture when the wound is dry and receives moisture when the wound site is substantially wet). The reduced pressure, apertures, and moist tissue-interface layer help with liquid management and otherwise promote re-epithelialization. Other systems, apparatuses, and methods are presented.
Wound dressing for wound treatment in a damp or wet environment
The disclosure relates to a wound dressing comprising a fibre fleece-based body, and a packaging forming the outer visible sides of the wound dressing, which packaging contains a layer made from a flat textile on the side of the wound dressing facing the wound, which has an outer-side, partially and structurally applied coating, and wherein the packaging has a fibre fleece layer on the side of the wound dressing facing away from the wound, which forms the outer visible side of the wound dressing; and, a liquid-impermeable plastic film layer on the side of the fibre fleece layer facing the wound, and wherein the fibre fleece layer, the plastic film layer, the body and the textile layer are not connected to one another, but rather lie with the flat sides thereof loosely and movably against one another and are only connected along the peripheral edges by a joint connection.
VACUUM WOUND THERAPY WOUND DRESSING WITH VARIABLE PERFORMANCE ZONES
A dressing for an open wound includes a cover layer dimensioned for positioning relative to a wound bed. The cover layer permits an evacuation of the space around the wound bed such that a sub-atmospheric pressure may be established to stimulate healing and facilitate the removal of fluid from the wound. Multiple performance zones in the cover layer allow the wound dressing to remain in position through repeated cycles of evacuation without placing undue strain on the wound bed. An outer peripheral zone may include a high peal-strength adhesive while an intermediate zone may include a shear resistant adhesive. A central zone may be devoid of any coating to maximize moisture transmission through cover layer.
Precut adhesive body support articles and support system
The invention provides an adhesive support article for supporting a body part of a user. A single-sided stretchable adhesive tape blank is precut into a sheet having a central anchoring portion and a plurality of outwardly extending fingers. The sheet is marked with visual indicators to guide the user of the support article for applying the central anchoring portion onto a first exterior surface of the body part and for stretching the fingers before adhering them at a predetermined distance away from the central anchoring portion. The adhesive support article can also be provided in a support system with at least one corresponding body landmark article, providing further guidance for applying the support article to the desired body part.
WOUND DRESSING WITH HUMIDITY COLORIMETER SENSOR
A wound dressing includes a superabsorbent pad, a drape layer, a humidity chamber, a wick, and a humidity colorimeter sensor. The superabsorbent pad is configured to absorb wound fluid and has a first side and a second, wound- facing side. The drape layer is coupled to the first side of the superabsorbe nt pad and has a first side and a second, wound- facing side. The drape layer is substantially impermeable to liquid and substantially permeable to vapor. The humidity chamber is coupled to the first side of the drape layer opposite the superabsorbent pad. The wick extends through the drape layer and is configured to wick moisture between the superabsorbent pad and the humidity chamber. The humidity colorimeter sensor is located within the humidity chamber and configured to change color responsive to a humidity level within the humidity chamber.
Breathable instant cast
An instant breathable cast includes an inner sleeve of an absorbent moisture wicking porous innermost layer allowing air and liquid to pass through and a shock absorbing intermediate layer having a plurality of openings therein allowing air and liquid to pass there through; and a protective outer sleeve having a plurality of openings therein allowing air and liquid to pass there through; and method of application thereof.

POROUS WOUND DRESSING FOR USE IN NEGATIVE-PRESSURE THERAPY
A porous wound dressing for use in negative-pressure therapy is proposed. The wound dressing has an outer edge which defines a substantially oval or rectangular outer shape of the wound dressing with a major axis and a minor axis. The wound dressing has one or more incisions or perforations which together form one or more arc-shaped lines and serve for cutting the wound dressing to size in order to adapt the wound dressing to the shape and/or size of a wound. The one or more arc-shaped lines each extend asymmetrically with respect to the major axis and/or to the minor axis and each enclose, together with a portion of the outer edge, a segment of the wound dressing that is designed for separation from the wound dressing.
Polyurethane foam sponge and wound dressing having the same
Disclosed herein is a polyurethane foam sponge produced by the steps of a) providing an hydrophobic polyol which has six hydroxyl groups, b) providing a hydrophilic diisocyanate obtained by reacting a diisocyanate with a hydrophilic polyether diol, c) reacting the hydrophobic polyol with the hydrophilic diisocyanate to obtain a prepolymer which includes 3 to 6 isocyanate groups, and d) mixing the prepolymer with a hydrophilic polyether polyol, a blowing agent, an end-capping agent, a reinforcing agent, and a catalyst to obtain the polyurethane foam sponge. A wound dressing including the polyurethane foam sponge is also disclosed.
Integrated temperature sensitive wound dressing device
The present invention pertains to an integrated wound dressing device for treatment of an insertion site of percutaneous and drug delivery devices. The integrated wound dressing device preferably comprises a transparent film layer having a bottom side, a top side and a perimeter. The bottom side is coated with an adhesive impregnated with an antimicrobial agent. The transparent film has a radius cutout between a central opening and the perimeter. A liquid crystal temperature sensitive film with an adhesive placed on the top side of the transparent film layer is preferably near and around the central opening. The dressing also has a layer of double folded release paper below the bottom side of the transparent film layer. The preferred TLCs used are cholesteryl esters with a preferable temperature detection range of 35-40 C. The preferred antimicrobial agent is chlorohexidine gluconate (CHG).
