  • Portable progressive and intermittent traction machine
    Patent number: 4266537
    Abstract: A portable traction machine for applying a traction force to a patient via a cord. The traction force may be applied either statically for a time set by a master timer or intermittently, the force alternating between pre-set maximum and minimum force levels. The time at each force level is independently controllable. In addition, intermittent or static traction may be applied progressively, in selected increments, where the amount of each increase and the time at each force level are independently adjustable. A novel means for sensing the force level in the cord for accurately controlling such force level is also disclosed.
