ABSTRACT:
A reprocessing unit for the reprocessing of a device having internal passageways by applying a fluid at a plurality of pressures to the internal passageways of the device to permit reuse of the device in a clean environment, the reprocessing unit including a pressure differentiation device for receiving a fluid having a single input pressure, the pressure differentiation device having first and second pressure control fittings for providing first and second differing pressure outputs in accordance with the single input pressure.Also included are tubing for transmitting the fluid at the first and second differing pressures from the pressure differentiation device to the internal passageways whereby the internal passageways are reprocessed with the transmitted fluid at the first and second differing pressures and the internal passageways are reprocessed at differing pressures in accordance with the single input pressure.
