  • Patent number: 6835256
    Abstract: A laminated composite suitable for use in medical products such as tapes and wraps. The composite includes, for example, a first nonwoven fiber layer, an elastic layer, a melt blown adhesive fiber layer, and a second nonwoven fiber layer. A scrim layer serves as a deadstop, or stretch limit, to prevent over stretching. The non-woven fiber layer(s) and/or the scrim layer form suitable loops for a hook and loop fastening system. The scrim layer in some embodiments is employed to make the composite finger tearable. The melt blown adhesive layer, nonwoven web layer and elastic layer form a breathable, porous elastic composite. Methods of manufacturing the composite are also disclosed.

  • Patent number: 6132835
    Abstract: The present invention provides an article comprising a curable resin and a filler associated with the resin. The incorporation of fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material as well as to the handling properties of the uncured casting tape or bandage. The incorporation of fillers into the casting materials of the present invention also imparts air and vapor porosity to the cured casting materials. If desired articles of the present invention may also incorporate fibers (either individually, bundled, or in the form of a light-weight scrim) to provide increased cohesiveness to the uncured article. Extremely moldable casting tapes are also provided which comprise a highly-filled composite material coated on a light-weight scrim. The casting tapes of this embodiment handle like traditional plaster of Paris casts yet cure to a weight-bearing cast in less than one hour.

  • Patent number: 6074354
    Abstract: The present invention provides an orthopedic casting article comprising an apertured, extruded sheet. The present invention also provides a method of enclosing a body member, comprising the steps of: heating an apertured, extruded sheet comprising a low temperature thermoplastic polymer having a softening or melting temperature less than about 90.degree. C.; wrapping the article about the body member; and molding the wrapped article about the body member such that the article is used as an orthopedic casting material and has a sufficient number of apertures after application to the patient to allow moisture vapors produced by the skin to freely escape through the cast or splint.

  • Patent number: 5593628
    Abstract: The present invention provides a method of making an orthopedic casting article comprising an apertured, extruded sheet. The method involves the steps of charging an extrudable material selected from the group consisting of low temperature thermoplastic polymers and viscous curable resins to an extruder; and extruding the material through a die to form an apertured sheet. The sheet is used as an orthopedic casting material and has a sufficient number of apertures after application to the patient to allow moisture vapors produced by the skin to freely escape through the cast or splint. The sheet preferably has at least 20 percent aperture volume. The apertured, extruded sheet may optionally contain a filler associated with the resin. The incorporation of fillers adds substantially to the strength of the cured casting material as well as to the handling properties of the uncured casting tape or bandage.

  • Patent number: 5540982
    Abstract: The present invention provides a unique knit construction having a nonfiberglass stiffness-controlling yarn in the fabric of the backing. Preferably, the nonfiberglass stiffness-controlling yarn is used in combination with a heat shrinkable yarn or a stretch yarn, and alternatively a nonfiberglass microdenier yarn. More preferably, the nonfiberglass stiffness-controlling yarn is in combination with a stretch yarn and a nonfiberglass microdenier yarn. Most preferably, the nonfiberglass stiffness-controlling yarn is in combination with a heat shrinkable, elastically extensible yarn, and a nonfiberglass microdenier yarn.
