A METHOD FOR DETERMINING THE EXISTENCE OF OBSTRUCTIONS IN THE PASSAGEWAYS OF A MEDICAL INSTRUMENT

摘要

A method for the reprocessing of a device (96) having internal passageways (98a-e) 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 includes applying a fluid having a single input pressure to a pressure differentiation device (252) having first (257) and second (259) pressure control fittings for providing first and second differing pressure outputs in accordance with the single input pressure and transmitting the fluid at the first and second differing pressures from the pressure differentiation device to the internal passageways. The internal passageways are reprocessed with the transmitted fluid at the first and second differing pressures, whereby the internal passageways are reprocessed at differing pressures in accordance with the single input pressure.
