  • Patent number: 4825852
    Abstract: A continuous passive motion device comprises a base and femoral and tibial supports which rotate about a first pivot point located at the knee, the femoral support also rotating about a pivot point which comprises an extension of the base and is located adjacent the patient's hip. The motor is located in the base beyond the end of the travel of drive rods which extend from the base to the tibial support. The motor drives the foot of these rods forward and backward along the base. The drive rods move from a nearly horizontal positon relative to the base up to a vertical positon and past this vertical position. A camming mechanism is provided coupling the upper end of the drive rods to the tibial support, the camming mechanism being engaged when the drive rods are nearly vertical, to provide additional rotational force to the tibial support which is conveyed to the knee joint. In this way, a powerful bending force is conveyed to the knee, to thereby provide the necessary rehabilitating force to the knee joint.

  • Patent number: 4432361
    Abstract: A completely portable, continuously self-monitoring device for expediting the healing of bone or soft tissue fractures or defects in a patient is disclosed herein along with its method of use. This device includes an electrical power supply, electronic circuitry and an arrangement of electrodes for applying current in a regulated manner through the fracture or defect site in a way which has been found to expedite the healing of bone fractures or bone defects at the site. The device also includes a monitoring arrangement cooperating with its power supply, electronic circuitry and arrangement of electrodes for continuously detecting and visually indicating whether or not the power supply is in proper working order and whether or not current is flowing through the fracture or defect site.
