    摘要: 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. A hand pump operated by the patient is fluidly connected to the at least one pneumatic chamber for injecting pressurized air into the at least one pneumatic chamber. The hand pump is capable of injecting at least 138 kPa (20 psi) of pressure into the pneumatic chamber. A pressure relief mechanism operated by the patient is adapted to release pressure from the at least one pneumatic chamber.

    摘要: A portable traction device suitable for cervical or lumbar 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.

    摘要: The present invention provides a wave generating apparatus for generating waves in for example beds, chairs and the like. The apparatus can be constructed to include a motor and crank assembly connected to a flexible sheet and a stationary inertial member. In one aspect of the invention there is provided an apparatus for generating wave motion, comprising a flexible member; an oscillatory drive means attached to said flexible member, said oscillatory drive means including a crank assembly having an axis of rotation; at least two link members each having opposed first and second end portions, the at least two link members being spaced apart a first pre-selected distance from each other and each being rigidly attached at their respective first end portions to said flexible member; and at least one elongate beam, said at least two link members being pivotally attached to the at least one elongate beam, and the elongate beam being attached to the crank assembly, for imparting oscillatory motion to the at least one elongate beam so that when the oscillatory drive means is engaged the at least one elongate beam undergoes oscillatory motion which produces transverse waves along the flexible member.
