REDUCED-PRESSURE DRESSING ASSEMBLIES FOR USE IN APPLYING A CLOSING FORCE
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.
Skin contact material
A substrate based skin contact material formed from a hydrocolloid having a silicone based component extending over regions of the substrate surface. The adhesive is formed non-continuously over the substrate to provide areas devoid of adhesive to allow appreciable moisture transfer between the skin and substrate and improve the skin friendliness of the material during use and allow convenient removal with avoidance of skin irritation.
Wound dressing
A wound dressing including a layer in the form of a strip and including gel-forming fibers, the strip having longitudinal lines of stitches formed from a thread and transverse lines of stitches formed from a thread. In certain forms, the wound dressing includes at least one stitch free column.
Manufacturing method for wound dressings
A wound dressing having a thin barrier layer of soft, pliant adhesive material with a flexible cover layer extending along one side of the adhesive layer and a removable release sheet on the opposite side is disclosed. The adhesive material has a center and border surrounding the center such that the adhesive is contoured. A method for making the contoured dressing using a gear pump and a laminating roller having a predetermined softness and firmness is also disclosed.
SKIN CONTACT MATERIAL
A substrate based skin contact material formed from a hydrocolloid having a silicone based component extending over regions of the substrate surface. The adhesive is formed non-continuously over the substrate to provide areas devoid of adhesive to allow appreciable moisture transfer between the skin and substrate and improve the skin friendliness of the material during use and allow convenient removal with avoidance of skin irritation.
Wound dressing garment
A wound dressing garment is provided. The wound dressing garment includes a wearable garment including a portion having a hole configured to receive a wound dressing therein in combination with the wound dressing. The wound dressing includes a border connecting the wound dressing to the wearable garment where the border extends around the perimeter of the hole to locate the wound dressing therein. The wound dressing may include one or more additional layers including a hydrogel layer. A method for treating wound or preventing bed sores using the wound dressing garment is also provided.
Healthcare textiles
Single layered nonwoven wound dressings containing (1) about 5% by weight to about 95% by weight (e.g., 5% to 95%) non-scoured, non-bleached greige cotton fibers, (2) about 5% by weight to about 95% by weight (e.g., 5% to 95%) bleached cotton fibers, and (3) about 5% by weight to about 60% by weight (e.g., 5% to 60%) hydrophobic fibers (e.g., polypropylene, nylon); all percentages adding up to 100 wt %. Also, multi-layered nonwoven wound dressings, containing (1) at least one inner layer containing (a) about 50% by weight to about 95% by weight (e.g., 50% to 95) non-scoured, non-bleached greige cotton fibers and (b) about 5% by weight to about 50% by weight (e.g., 5% to 50%) hydrophobic fibers, all percentages adding up to 100 wt %, and (2) at least one outer layer containing (a) about 5% by weight to about 95% by weight (e.g., 5% to 95%) non-scoured, non-bleached greige cotton fibers, (b) about 5% by weight to about 95% by weight (e.g., 5% to 95%) bleached cotton fibers, and (c) about 5% by weight to about 60% by weight (e.g., 5% to 60%) hydrophobic fibers (e.g., polypropylene, nylon); all percentages adding up to 100 wt %.
Wound dressing
The present application is concerned with an improved wound dressing for use in the treatment of skin wounds with some level of exudation, especially for use in those wounds which are infected or under risk of being infected by microorganisms.
POST-OPERATIVE FOAM AND SUPER-ABSORBENT DRESSING
A dressing includes a hydrophilic foam layer having a longitudinal central axis configured to overlay the incision, a drape coupled to an outwardly-facing side of the hydrophilic foam layer, a first row of superabsorbent material positioned on the outwardly-facing side of the hydrophilic foam layer, and a second row of superabsorbent material positioned on the outwardly-facing side of the hydrophilic foam layer. The first row and the second row are spaced laterally apart from, and on opposite sides of, the longitudinal central axis. The drape includes a first window aligned with the first row and a second window aligned with the second row. The first window and the second window include a film, different from the drape, configured to facilitate evaporation therethrough.
Super-absorbent, reduced-pressure wound dressing and systems
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.
