Abstract: A knee brace includes a novel knee hinge having a first arm member, a second arm member, and a cover piece. The first arm member serves as a femoral brace. A cam follower is mounted on one side of the first arm member. The second arm member serves as a tibial brace. The second arm member includes a generally heart-shaped aperture which is a cam for the hinge. The cam defines a continuous cam wall which is adapted to receive and mate with the cam follower. The dimensions of the cam are such that upon engagement of the cam follower with the cam, each semicircular end of the cam follower is in slidable contact with the cam wall during movement of the cam follower, and the edge of the cam follower closest to the cam node is in slidable contact with the cam node during movement of the cam follower. The cam follower rotates about the cam node and permits a degree of motion between full flexion and full extension. The cover piece is adapted for placement atop the mated first and second arm members.

Abstract: An improved antimicrobial coated product and a method for coating substrates, the product of which is capable of withstanding high impact, is not subject to corrosion, is resistant to germ retention and transfer, and thus is extremely well suited for the containment of toxic, hazardous, corrosive, and bacteria-laden wastes as well as for products which are resistant to attack from fungus, positive and negative bacteria, yeast infections and contaminations, and viruses, as well as resistant to attack from corrosion, corrosive chemicals, caustic chemicals, and radiation. The substrate is coated with a thermoplastic material incorporating an antimicrobial agent by electrostatic, fluidized bed or flame spraying techniques. Alternatively, the substrate may be coated with a combination of a thermosetting resin and a thermoplastic material, either or both incorporating an antimicrobial agent, all of which can be cured in place.

Abstract: A hinged limb immobilizer device for setting and securely maintaining a predefined range of motion for a limb, requires no special tools for installation or adjustment. Limit stops are adjusted by simply loosening the appropriate thumbscrew, and moving the limit stop to the prescribed setting. Separate color-coded, labelled scales for flexion and extension match-up with separate color-coded thumbscrews to avoid misunderstandings. Security of adjustment is optimized by limit stops which embody both friction stop and positive stop characteristics, resulting in a unique "three-point locking" mechanism.
