The invention herein relates to a wound dressing product, combining a hydrophobic fabric, which is to be placed towards the wound, and is capable of binding unwanted microorganisms, and a moisture carrying matrix such as a gel or a foam. The product of the invention is ideal for treatment of drier wounds. It protects the wound and reduces the number of pathogenic microorganisms, without using antimicrobial substances and at the same time adds or traps moisture to the wound both supporting the hydrophobic functioning of the pad and healing in general by keeping the wound moist.

A wound dressing comprising a layer in the form of a strip and comprising gel-forming fibers, the strip having longitudinal lines of stitches formed from a thread and transverse lines of stitches formed from a thread.

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.

A super-absorbent dressing assembly for use with a reduced-pressure wound treatment system includes a breathable, fluid restricted dry layer for placement against a wound, a super-absorbent layer, and a non-breathable layer, and a drape extending over the non-breathable layer. A reduced-pressure interface is available to fluidly couple the super-absorbent layer to a reduced-pressure subsystem. The super-absorbent dressing assembly preferably supplies a compressive force when placed under reduced pressure. A reduced-pressure treatment system uses a super-absorbent bolster to treat wounds, e.g., linear wounds.

A closing dressing bolster and assembly for use with a system for treating a linear wound on a patient includes a bolster body formed from a flexible closing bolster material having closing members that are operable to develop an inward closing force when the closing dressing bolster is placed under reduced pressure. In one aspect, when the closing dressing bolster is under reduced pressure, the system, dressing, or assembly develops an inward force realized at the linear wound and a compression force. A wicking-material holder and wicking material may be used as well. The member components may all be see-through to allow visual inspection of the wound without requiring removal of the dressing.

A polyether having a functional group that is reactive to isocyanate with at least one polyisocyanate, which has an average isocyanate functionality in the range of 2.4 to 3.5, and at least one vinyl compound, which has a functional group that is reactive to isocyanate, wherein the molar ratio of polyether to vinyl compound lies in the range of 3:1 to 1:3 and the ratio of the sum of the molar quantities of polyether and vinyl compounds to isocyanate groups lies in the range of 1.5:1 to U.5. Corresponding vinylterminated prepolymers have the advantage of low visocity together with good water solubility and therefore can be used advantageously for applications as injection agents.

A wound dressing is in the form of a strip or a ribbon. The strip or ribbon is made of gel-forming fibers and has longitudinal lines of stitches formed from a thread and transverse lines of stitches formed from a thread.

The present invention relates to a resilient wound dressing and absorbent articles for a resilient wound dressing. The present invention also relates to a method of manufacturing a resilient wound dressing as well as method of manufacturing a resilient absorbent article for a wound dressing.

A reduced-pressure system for treating tissue, such as damaged subcutaneous tissue, includes a shaped dressing bolster for placing on the patient's epidermis and substantially sized to overlay the damaged subcutaneous tissue. The system further includes a sealing subsystem for providing a fluid seal over the shaped dressing bolster and a portion of the patient's epidermis, and a reduced-pressure subsystem for delivering a reduced pressure to the sealing subsystem. The reduced-pressure system may develop a force, which may include a vertical force that is realized at tissue site deeper than the epidermis or a closing force directed towards the incision. The shaped dressing bolster is shaped to evenly distribute the force. Other methods and systems are included.
