  • Anatomically correct continuous passive motion device for a limb
    Patent number: 5239987
    Abstract: A bilateral anatomically correct continuous passive motion orthosis device for a limb having pivotally connected first and second body portions. The device includes a base having a proximal end and a distal end. A first carriage member receives the first body portion and is pivotally connected to a second carriage member which receives the second body portion. The second carriage member is also pivotably connected to the base. A drive mechanism moves the first carriage member between the distal and proximal ends of the base. A speed control device controls the velocity of the first carriage member between the distal and proximal ends of the base such that the first carriage member pivots about a first support pivot axis with respect to the second carriage member at a predetermined angular velocity. A biasing mechanism is provided to assist the drive mechanism in lifting the limb.
    Type: Grant
