  • Patent number: 8420882
    Abstract: A method of providing moisture therapy to a subject by applying a moist therapy compress against a treated body portion. The moist therapy compress includes a fluid-permeable shell, a flexible backing fastened to the shell to define an enclosure, and a hydrophilic zeolite fill granules loosely contained within the enclosure. The therapy compress is exposed to a source of moisture to cause absorption of water into the a hydrophilic zeolite, and the moisture is delivered from the hydrophilic zeolite through the fluid permeable shell to the treated body portion.

  • Publication number: 20120083724
    Abstract: Devices, kits and methods described herein may be for wound healing, including the treatment, amelioration, or prevention of scars and/or keloids by applying and/or maintaining a pre-determined strain in an elastic skin treatment device that is then affixed to the skin surface using skin adhesives to transfer a generally planar force from the bandage to the skin surface. Applicators are used to apply and/or maintain the strains, and some of the applicators are further configured to provide at least some mechanical advantage to the user when exerting loads onto the skin treatment device.

  • Publication number: 20120065566
    Abstract: There is provided herein a bandage folded upon itself to have a plurality of panels or rolled and a device having an elongated body portion and end elements at its two opposite ends sized and shaped to extend through several panels of the folded bandage, and retain the bandage in a folded configuration, while allowing a user to unfold the bandage without removing the device. The bandage may be unfolded, panel-by-panel, by pulling on an end panel of the bandage, causing it to be released from the device, and pulling on released panels or topmost retained panels to free the topmost retained panels, each in turn.

  • Publication number: 20120046591
    Abstract: Devices, bandages, kits and methods are described that can control or regulate the mechanical environment of a wound to ameliorate scar and/or keloid formation. The mechanical environment of a wound includes stress, strain, and any combination of stress and strain. The control of a wound's mechanical environment can be active, passive, dynamic, or static. The devices are configured to be removably secured to a skin surface in proximity to the wound site and shield the wound from endogenous and/or exogenous stress.

  • Patent number: 8114433
    Abstract: A hemostatic device for promoting the clotting of blood includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood emanating from the wound to cause the clotting. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. A hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.

  • Publication number: 20120029406
    Abstract: A dressing for applying compression to a wound in a patient includes a bladder having a non-deformable end wall and a deformable membrane. The dressing may include a flexible web having an adhesive layer on one side thereof for securing the dressing to the patient so as to hold the bladder against the patient's skin. Upon inflation, the deformable membrane projects towards the patient's skin and exerts pressure on the wound to reduce the flow of blood from the wound.

  • Patent number: 8084663
    Abstract: A wound dressing having a suction member adaptable for connection to a source of vacuum pressure. The wound dressing preferably has a hydrophobic or biodegradable base layer and one or more absorptive layers for absorbing fluid from the wound. The absorptive layers are preferably quilted with patches containing desiccant, adsorbent, or absorbent material. Alternatively, the wound dressing may allow fluid to pass through the suction member. A semi-permeable cover is provided for allowing the wound to breathe while protecting the wound from undesirable substances such as bacteria, viruses, or fluids. The cover may have a bladder for distributing contact pressure away from the wound. Various sensors may be provided in the wound dressing for sensing various physiological parameters in the wound, such as oxygen saturation, blood pressure, respiratory rate, blood glucose, and serous fluid turbidity. Medicine may also be applied to the wound through the wound dressing.

  • Patent number: 8062272
    Abstract: A wound treatment appliance is provided for treating all or a portion of a wound. The appliance generally comprises a flexible overlay that covers all or a portion of the wound for purposes of applying a reduced pressure to the covered portion of the wound. The wound treatment appliance may also include a vacuum (including a suction bulb) system to supply reduced pressure to the wound in the area under the flexible overlay. In yet other embodiments, the wound treatment appliance may also include a suction drain, wound packing material to prevent overgrowth of the wound or to encourage growth of the wound tissue into the wound packing material, a collection chamber to collect and store exudate from the wound, or combinations thereof. Finally, methods are provided for using various embodiments of the wound treatment appliance.

  • Publication number: 20110282261
    Abstract: A compression bandage shaped as an elongate rectangle is made of a textile fabric on which a hook strip is fastened along a narrow side of a small portion of a lateral face, or hook side. The fabric contains elastic filaments running in a longitudinal direction and, in a transverse direction, includes virtually inelastic supporting filaments having a spring constant in the longitudinal direction that ranges from 0.3 to 3 Newtons/cm of longitudinal stretching and a per meter length and per decimeter width of the compression bandage. Small loops made of soft filaments are interwoven and distributed uniformly over the entire area of the lateral face, or fleece side, opposite the hook strip. These small loops are oriented approximately perpendicularly to the lateral face, in size and distance from one another, and are complementary to the hooks of the hook strip for forming a releasable hook-and-loop closure.
