  • Patent number: 11850178
    Abstract: A supportive brace to be worn circumferentially around the forearm for preventing and reducing pain and discomfort associated with epicondylitis (Tennis Elbow or Golfer's Elbow) of the elbow is disclosed. The brace includes a padded counterforce strap assembly band circumferentially fitted around the forearm. The strap assembly has an elastomeric buttress positioned to apply targeted compression to the ECRB. A toric ring forms a cushioned border around the concavity on the dorsal face of the elastomeric buttress, so that when the band is fittingly secured around the forearm about 1-1.5 in distal to either of the epicondyles, the hemispherical/ovaloid convex shape on the inside face of the elastomeric buttress exerts controlled pressure to tissues associated with the epicondylitis.

  • Patent number: 10876232
    Abstract: A conventional sock, in which a pile yarn knitted into loops together with a polyurethane yarn has cushioning properties, but has a problem in that it cannot be used for a long period of time. According to the present invention, a first component yarn 15a composed of two yarns, namely, a woolly nylon yarn 13a and a cotton yarn 14a, and a second component yarn 15b composed of two yarns, namely, a woolly nylon yarn 13b and a cotton yarn 14b, are alternately knitted into float loops every 10 loops. Accordingly, the cotton yarns that are less stretchable appear on the surface, and thus cushioning properties can be improved. Also, the yarn strength can be increased by the woolly nylon yarns that are highly stretchable, and also the strength can be further increased by using the component yarns each composed of two yarns: a woolly nylon yarn; and a cotton yarn. Accordingly, the obtained sock can be used for a long period of time.

  • Publication number: 20140058309
    Abstract: A method of making a wound dressing comprising the steps of: providing an apertured substrate layer; coating the substrate layer with a fluid silicone prepolymer composition; thermally partially curing said silicone prepolymer composition to form a partially cured silicone coating on the substrate; laminating the coated substrate layer to a base layer to form a laminate having said partially cured silicone coating in contact with a surface of the base layer; followed by exposing the laminate to ionizing radiation, to further cure the partially cured silicone coating and to bond the silicone coating to said surface of the base layer. The radiation cure results in strong bonding between the siliconized substrate and incompatible base layers such as polyurethane foams. Also provided are wound dressings obtainable by the process of the invention.

  • Patent number: 8563798
    Abstract: A bandage for improved wound care is disclosed. The bandage comprises a non-adherent, deformable inner layer, a leak-proof outer layer that is substantially coextensive with the inner layer, and an absorbent middle layer contacting both the inner and outer layers. An adhesive strip and adhesive tabs along the bandage's side attach and adjust the fit of the bandage to securely hold the absorbent layer in contact with the wound, without any adhesive touching the skin, thereby eliminating pain and discomfort upon removal or replacement. The bandage allows substantial freedom of motion without slipping. The adhesive strip and tabs secure the bandage in place without any adhesive touching the skin, thereby providing convenience and causing no pain or discomfort upon removal or replacement of the bandage. The bandage may use a non-stick netting material layer to improve patient comfort, and elastic cuffs to improve fit and leakage.

    Abstract: Examples of multi-layer bandages and methods for dressing a wound are described. An example multi-layer bandage includes a first layer and second layer and an optional third layer. An exemplary method for dressing a wound may include applying a bandage having a top layer, a middle layer, and a bottom layer to a wound with the bottom layer being provided in contact with the wound, wherein the top layer includes an adhesive for securing the bandage to a surface near the would, and where the bottom layer includes copper; and allowing the bandage to remain over the would for a predetermined period of time. In some examples, the method may further include removing the bottom layer without removing the top and middle layers. In other examples, the method may include removing the bandage when the middle layer or the bottom layer change in color.
