Abstract:
An extracorporeal blood processing system in which blood is removed from an individual for processing and returned to the individual, said system comprising:a blood removal conduit for transferring blood from a donor/patient; a blood return conduit for transferring blood to a donor/patient; said blood removal conduit and said blood return conduit being in fluid communication; and a disposable assembly including a pressure sensing station and a plurality of integral passageways for transporting blood, each of said plurality of integral passageways being partially defined by at least one of said blood removal conduit and said blood return conduit; said pressure sensing station including a diaphragm member mounted to said disposable assembly, said diaphragm member having a first surface being in direct fluid communication with one of at least said blood removal conduit and said blood return conduit, said diaphragm member being movably responsive in relation to the fluid pressure commonly occurring within each of such blood removal and blood return conduits; a sensor for determining a pressure in one of at least said blood removal conduit and said blood return conduit; and means for removably attaching a second surface of said diaphragm to said sensor wherein said pressure sensing station co-acts with said sensor to measure the fluid pressure commonly occurring within each of said blood removal and blood return conduits.
