Zusammenfassung:A pneumatic control device (20) includes a housing (22), a pressure control member (24) secured to the housing, a first fluid-conduit member (28), and a first sensor (32). The pressure control member s constructed and arranged to selectively change a fluid pressure within the control member. The first fluid-conduit member is in fluid-flow communication with the pressure control member. The first sensor is in fluid-flow communication with the first fluid-conduit member. The sensor is constructed and arranged to generate a control signal based upon the fluid pressure within the control member. Analogous to pressure control member (24), the second pressure control member (26) is connected to second fluid conduit (36) and sensor (38). The pneumatic controller is used to produce a variable control signal to control a rate of fluid dispersement to a patient in an angiographic system.
