  • Patent number: 4723974
    Abstract: A container assembly to provide a cooling environment for a severed extremity to facilitate transporting of the extremity to a hospital or other similar location for the purpose of facilitating replantation of the extremity to the patient.

  • Patent number: 4669106
    Abstract: An apparatus for repositioning (by depressing) shoulders of a prone patient at a displaced position to facilitate the obtaining of an unobstructive lateral radiograph (X-ray) of all seven (in number) vertebrae of the cervical section of the spine. The apparatus of the present invention utilizes an elongated substantially planar board upon which the patient is to be located in a prone position. A perineal post is mounted on the board and is to contact the patient at the perineal area, basically immobilizing the torso of the patient. A movable plate is mounted on the upper end of the board which includes a pair of bracket assemblies which are to be in contact with the shoulders of the patient. The plate includes a manually operated winch assembly which when operated applies pressure against the shoulders of the patient moving such to a displaced position to thereby facilitate the taking of the lateral radiograph of the cervical section of the spine.
