Abstract
The present invention is a multi-function fluid communication control system for effecting selective automated control to provide selected fluid communication between fluid reservoirs, instruments, and various pressure conditions which can be used in, for example, a catheterization procedure. The system includes multi-port fluid communication valves, such as three-port stopcocks which are connected as required by fluid conduits such as tubes. Each of the valves, in turn, are connected to a control mechanism such as stepper motors to provide the necessary fluid communication paths in response to the user's requirements. User requirements can be translated into the required valve movements through command signals operated by, for example, an appropriately programmed computer or microprocessor.
