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-relieving pressure feature of the regulator. The traction force is controllable and varied by manual adjustment of the pressure control knob to provide the set cylinder pressure in dependence on the traction force to be applied to the patient's body. The traction device includes modular components for storage as a kit in a portable bag or case. For example, the traction device further includes a connector member receivable coaxially in the second end region of the tubular housing for joining the tubular housing to a hollow tubular extension housing to provide increased length to the tubular housing. Still further, the traction device may further include an elongated boom member releasably fastenable to the end region of the tubular housing or the extension post or housing, if employed, so as to extend laterally therefrom. The boom member includes a plurality of cable guide pulleys for directing the traction cable means in a particular manner depending on the particular region of the patient's body to be tractioned.
