ABSTRACT:
A pneumatic control device includes a housing, a pressure control member secured to the housing, a first fluid-conduit member, and a first sensor. The pressure control member is 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. In preferred systems, the pneumatic controller is useful for producing a variable control signal to control a rate of fluid dispersement to a patient in an angiographic system.
