Traction bed

摘要

A traction bed includes a frame upon which an individual is supportable, first and second lever arms pivotably coupled to the frame at a location proximate a first end of the frame and configured to be coupled to the individual's upper torso, third and fourth lever arms pivotably coupled to the frame at a location proximate a second end of the frame and configured to be coupled to the individual's pelvis or pelvic region, and a control system operable to direct a force onto each of the lever arms to pivot the lever arms relative to the frame. The force directed to the first and third lever arms is separately variable from the force directed to the second and fourth lever arms to provide differential traction on the individual's body.

1. A traction bed comprising:
a frame upon which an individual is supportable; first and second lever arms pivotably coupled to the frame at a location proximate a first end of the frame and configured to be coupled to the individual's arms; third and fourth lever arms pivotably coupled to the frame at a location proximate a second end of the frame and configured to be coupled to the individual's legs; a control system operable to direct a force onto each of the lever arms to pivot the lever arms relative to the frame, wherein the force directed to the first and third lever arms is separately variable from the force directed to the second and fourth lever arms; a plurality of extensible members each coupling one of the lever arms to the frame; wherein the extensible members are pneumatic cylinders, and wherein the control system includes a first pressure regulator configured to vary an air pressure delivered to the pneumatic cylinders associated with the first and third lever arms, a second pressure regulator configured to vary an air pressure delivered to the pneumatic cylinders associated with the second and fourth lever arms, and a third pressure regulator positioned upstream of the first and second pressure regulators, and wherein the third pressure regulator is in fluid communication with a source of pressurized air and operable to set a maximum air pressure capable of being delivered to all of the pneumatic cylinders.
