Abstract
A pneumatic ambulatory traction device comprises modular components that can be readily stowed at a facility or in a vehicle with minimum as-stowed space requirements and that can be readily and quickly assembled into a compact traction device usable at a facility, in a vehicle, at an accident site and the like to provide pneumatic traction force to a patient's body in a manner that can be controlled and varied as may be needed. The traction device comprises an elongated tubular housing connectable to a support, which may include an operating table or bed or a stretcher in a vehicle or at an accident site. A pneumatic cylinder is disposed in the housing and a piston is received in the cylinder and includes a piston rod movable in response to cylinder pressure to apply a traction force correlated to the cylinder pressure via a flexible cable connected to the piston rod and to a patient's body. A self-relieving pressure regulator is disposed on an exterior of the tubular housing and is communicated to the cylinder. The regulator includes a pressure control adjustment knob that is manually adjusted to provide a set cylinder pressure which will not be exceeded by virtue of the self-rel…
