Controlled strain skin treatment devices and methods
Devices, kits and methods are used for wound healing, including but not limited to the treatment, amelioration, or prevention of scars and/or keloids, and include packaging, manipulation elements, applicator and/or tensioning device that are used to apply and/or maintain a strain in an elastic dressing.
Drape having microstrain inducing projections for treating a wound site
Systems and apparatuses for administering reduced pressure treatment to a tissue site include a reduced pressure source, a drape having a plurality of projections for contacting the tissue site, and an adhesive connected to at least a portion of the drape for sealing the drape to a portion of a patient's intact epidermis.
Systems and methods for monitoring compression with compression bandages having stretchable electronics
Systems and methods are described for monitoring compression applied by a compression bandage to a body portion of an individual. A system embodiment includes, but is not limited to, a deformable substrate integrated with a textile configured to conform to a body portion; a sensor assembly coupled to the deformable substrate, the sensor assembly including one or more strain gauges configured to generate one or more sense signals associated with a strain of the textile; circuitry operably coupled to the sensor assembly and configured to receive the one or more sense signals associated with the strain of the textile; and a reporter operably coupled to the circuitry and configured to generate one or more communication signals responsive to instruction by the circuitry, the one or more communication signals associated with the strain of the textile.
FIBROUS SHEET
Provided are a fibrous sheet having a stress relaxation rate defined by the following formula of less than or equal to 85%:
stress relaxation rate [%]=(stress S.sub.5 at extension after five minutes/stress S.sub.0 at initial extension)100
when a stress at extension immediately after extension in an in-plane first direction at 50% elongation is defined as a stress S.sub.0 (N/50 mm) at initial extension, and a stress at extension at a time of extending in the first direction at 50% elongation for five minutes is defined as a stress S.sub.5 (N/50 mm) at extension after five minutes, and a bandage including the fibrous sheet.
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.
COMPRESSION GAUGE FOR THERAPEUTIC COMPRESSION GARMENTS
A method and apparatus for treating edema is disclosed. The method may include obtaining a compression garment comprising material having an end stretch. At least one gauge may be applied to the material. The compression garment may be applied to a patient. During the applying, the material may be stretched until the at least one gauge indicates that a proper amount of stretch has been reached. The at least one gauge may be tuned so that the material arrives at or near end stretch at substantially the same time that the at least one gauge indicates that the proper amount of stretch has been reached.
NEGATIVE PRESSURE WOUND CLOSURE DEVICES AND METHODS
Systems, devices, and methods of the present application can accelerate and reduce medical complications associated with healing of amputation wounds. The devices and methods utilize a compression structure and negative pressure to cause the amputation wound to preferentially close from the deepest portion of the wound to the shallowest portion.
Wound healing device
This invention provides wound healing systems, which delivers oxygen to the wound bed and applies negative pressure thereto, where the source of oxygen and negative pressure are simultaneously applied to distal sites of the dressing. Methods of treating wounds and methods of treating or preventing anaerobic infection of wounds using such systems are described.
Multilayer dressing device and method for preventing and treating pressure ulcers and chronic wounds
The present invention provides a device and method for preventing or curing pressure ulcers or chronic wounds. A multilayer dressing comprises a soft silicone jell layer of a suitable thickness which is placed in the multilayer dressing, above an absorbent layer. The matrix of the silicone jell layer is populated with a plurality of silicone beads of suitable size. The beads are connected to each other, and to the silicone jell layer. Breathing of wound and substantial supply of oxygen to the wound is duly insured for all layers of the multiple layer dressing. The beads play a pivotal role in promoting the effectiveness and performance of the multilayer dressing by acting as the plurality of effective cushions, as they absorb and uniformly redistribute a patient's body weight across the entire applied dressing area. The low adhering adhesive coating of about 5 mm in width is applied to the peripheral edges of all the layers. Unlike the multilayer dressing already available in the market, skipping the application of low adhering adhesive coatings on the entire top and bottom surfaces of the layers helps in promoting overall breathability and consequently, the efficiency of the multilayer dressing of the present invention.
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.
