Patent ID: 7356382

Claim:
A system for verifying that a particular fluid supply containing a fluid is connected to a flow control device, wherein a tube is connected to the fluid supply, the tube having an inner surface for carrying the fluid and an outer surface and the flow control device acts on a tube coupled to the fluid supply to control movement of the fluid from the fluid supply through the conduit, the system comprising: a pressure sensor coupled to the outer surface of the tube, the pressure sensor providing pressure signals representative of pressure in the tube; and a processor having a connection verification mode in which the processor is configured to monitor the pressure signals for a predetermined time period to detect an operator-induced pressure change and to provide a verification indication when the processor receives pressure signals indicative of the operator-induced pressure change in the conduit to thereby verify that the particular fluid supply is connected to the flow control device; wherein the processor in the connection verification mode is further configured to: prompt the operator to confirm that a pressure change has been induced if the operator-induced pressure change is not detected within the predetermined time period.
