  • Patent number: 11920048
    Abstract: Non-flammable structures are disclosed that have a substrate and a layer applied to the substrate that includes a phase change material that is flammable. The layer includes a binder having mixed therein about 50% to about 90% by weight of a microencapsulated phase change material and about 0.5% to about 10% by weight of an inorganic flame retardant. The inorganic flame retardant has a volume that increases upon exposure to heat or a flame. The binder is selected from the group consisting of a polyurethane, a styrene acrylic copolymer, a styrene butadiene copolymer, acrylic and combinations thereof.
    Type: Grant

  • Patent number: 5511548
    Abstract: A disposable biomedical electrode having a one-piece terminal secured therein without washers, retaining rings or other securement means is provided. The electrode also includes an electrolytic gel which exhibits greater patient comfort without any decrease in electrical performance. The gel layer is preferably a hydrogel material formed from an aqueous mixture of polyhydric alcohol, aliphatic diisocyanate terminated prepolymer, polyethylene oxide based polyamine, and sodium chloride.

  • Patent number: 5443440
    Abstract: A medical device is provided for applying compressive pressures against a patient's foot. The device comprises first and second panels of flexible material secured to one another to form an inflatable bag to be fitted upon the foot. The bag has first and second separate fluid bladders. The first fluid bladder is adapted to engage a first portion of the foot and the second fluid bladder is adapted to engage a second portion of the foot. A boot is provided for holding the inflatable bag to the foot. A fluid supply is provided for applying pressurized fluid to the first and second fluid bladders such that the first fluid bladder applies a first compressive pressure upon the first portion of the foot and the second fluid bladder applies a second compressive pressure upon the second portion of the foot.
