  • Patent number: 11957548
    Abstract: A composite moldable splint and method for using the same is described. In some embodiments, the splint has at least a partially fluid-filled inner volume, which in some embodiments may include foam, rubber, water, or pelletized material, enclosed by a flexible liner, surrounded by a thermoplastic layer that is flexible and moldable when heated. The inner volume, which may include a thermoactive adhesive having differing viscosity characteristics at a plurality of temperatures, provides the ability to mold the cushion into a wide range of shapes and contours, such as when forming around a body part. The thermoplastic layer provides the ability of the cushion to be molded when heated, while the inner volume tends to maintain a shape, and allows the thermoplastic layer to stay in its formed shape as the cushion cools. The cushion may be used in a range of medical applications for stabilizing patients and body parts.

  • Patent number: 9743494
    Abstract: A display case that includes a base for supporting an item that is being displayed; a cover engaged with the base, with the base forming an interior compartment for the item and having respective opened and closed positions relative to the base; a light source disposed in the interior compartment, supported at an internal surface of said cover and, when illuminated, casting a light beam on the item to highlight the item; and a sensor associated with at least one of the base and cover and for activating the light source. The sensor may include a motion detector, a light detector, a touch sensor or a proximity sensor.

  • Publication number: 20150059765
    Abstract: An immobilization system for a body, or body part, is provided, having a fixed form support and one or more shells that generally form an outlining structure of the body part to be immobilized. A formable support, having minimal mass, is molded and interposed between the fixed form support and shells to form a closely fitted support for the body part. The shell or shells may be removed from the system after molding, so that patient comfort is improved and total mass of the system is reduced, without compromise of the degree of immobilization. A retention mask, which also may be molded to conform to the body or body part, may be utilized to further stabilize positioning of the system.

  • Publication number: 20150065932
    Abstract: A composite moldable splint and method for using the same is described. In some embodiments, the splint has at least a partially fluid-filled inner volume, which in some embodiments may include foam, rubber, water, or pelletized material, surrounded by a thermoplastic layer that is flexible and moldable when heated. The thermoplastic layer may then be covered by a fabric or foam layer to provide comfort and to maintain overall dimensional stability when heated. The inner volume provides the ability to mold the cushion into a wide range of shapes and contours, such as when forming around a body part. The thermoplastic layer provides the ability of the cushion to be molded when heated, and to assume a rigid formed shape when the cushion cools. The cushion may be used in a range of medical applications for stabilizing patients and body parts.
