  • Patent number: 8083705
    Abstract: Low-cost, light weight portable cervical traction or spinal decompression devices for home use by a patient. A carriage is slidable along a portion of a support structure parallel to a longitudinal axis. The carriage includes a restraining mechanism adapted to releasably restrain a portion of a patient's body to the carriage. The pneumatic traction force generating apparatus is operatively coupled to move the carriage relative to the support structure when in a pressurized state. The pneumatic traction force generating apparatus is adapted to maintain a generally static traction force during a treatment period when in the pressurized state without additional pressurized air being supplied. A hand pump operated by the patient is fluidly connected to the pneumatic traction force generating apparatus to inject pressurized air. A pressure relief mechanism operated by the patient is adapted to release pressure from the pneumatic traction force generating apparatus.

  • Patent number: 7189214
    Abstract: A multi-axis cervical and lumbar traction table and method of using same. The traction table includes a support frame with a first body supporting portion and a second body supporting portion. The first body supporting portion is moveable relative to the second body supporting portion along a longitudinal axis. A securing system adapted to secure a patient to the first and second body supporting portions is provided. Linking mechanism is adapted to move the first body supporting portion along a path relative to the second body supporting portion, wherein the path comprises at least one rotational degree of freedom.

  • Patent number: 7108671
    Abstract: A low-cost, light weight portable lumbar fraction device for home use by a patient including a support structure having a longitudinal axis and a carriage slidable along a portion of the support structure parallel to the longitudinal axis. The carriage includes a restraining mechanism adapted to releasably restrain a portion of a patient's body to the carriage. The pneumatic fraction force generating apparatus includes at least one pneumatic chamber and at least one air inlet. The pneumatic traction force generating apparatus is operatively coupled to both the carriage and the support structure to move the carriage relative to the support structure when the at least one pneumatic chamber is in a pressurized state. The pneumatic fraction force generating apparatus is adapted to maintain a generally static fraction force for a period in excess of 10 minutes when in the pressurized state without additional pressurized air being supplied.

  • Patent number: 6971997
    Abstract: A method and apparatus for determining an adjusted traction force for the patient. The first body supporting portion is positioned in a non-horizontal configuration. A compensating force related to a weight of the first body supporting portion, a weight of an applicable portion of a patient's body, and an angle between the first body supporting portion and a horizontal plane is determined. The compensating force is applied to a desired traction force to determine the adjusted traction force. The adjusted traction force is applied to the patient by moving the first body supporting portion relative to the second body supporting portion along the longitudinal axis to affect the distance between the first body supporting portion and the second body supporting portion.

  • Patent number: 6899690
    Abstract: A portable traction device suitable for cervical traction powered by a pneumatic cylinder. The portable traction device includes a support structure having a longitudinal axis and a carriage slidable along a portion of the support structure parallel to the longitudinal axis. The carriage including restraining mechanism for releasably restraining a portion of a patient's body to the carriage. A pneumatic cylinder includes a cylinder housing attached to the support structure. The cylinder housing contains a piston and piston rod. The piston rod is attached to the carriage for moving the carriage along the longitudinal axis relative to the support structure when pressurized air is injected into the pneumatic cylinder. The piston has at least one pressure activated seal extending circumferentially around the piston for engagement with an inside surface of the cylinder housing. A bicycle-style hand pump fluidly connected to the pneumatic cylinder is provided for injecting pressurized air into the cylinder.

  • Patent number: 6468240
    Abstract: A self-seating occiput wedge system for applying a therapeutic traction force to the occipital areas on a patent's head. The self-seating occiput wedge system includes a pair of self-seating, upstanding occiput wedges rotatably mounted generally perpendicular to a carriage. The occiput wedges define opposing engaging surfaces arranged to engage with the occipital areas of the patient's head. End stops define a range of rotation about an axis of rotation for each of the occiput wedges. The range of rotation is about 20 degrees. A cervical traction device utilizes the occiput wedge system is also disclosed.
