Patent ID: 8151629

Claim:
A device for monitoring pressure in a fluid system comprising: a pressure monitor for placement in communication with a fluid in said fluid system, said pressure monitor generating a signal representative of a measured pressure; and a control means for receiving said signal representative of said measured pressure and comparing said measured pressure to a reference, wherein said pressure monitor and said control means are placed in communication with a fluid system, wherein said fluid system comprises: at least one fluid path section having a first end and a second end; at least one fluid connection means having a plurality of ports for interconnection and responsive to a connect command signal to assume a first position wherein fluid flows between at least two of said ports and responsive to a disconnect command signal to assume a second position in which fluid does not flow between any of said plurality of ports, at least one port connected to said first end for forming a fluid system configuration; and a controllable pressure source connected to said second end and responsive to a pressure command signal to create a source pressure on fluid in said fluid system, wherein said at least one fluid connection means has at least one first port and a second port, said at least one first port connected to a first fluid path section and said second port connected to a second fluid path section, wherein said control means is a source of said pressure command signal, and wherein said control means is a source of said connect command signal and said disconnect command signal.
