Abstract: A system for monitoring and regulating pressure and concentration in a moving fluid stream inside of a conduit is provided. The fluid stream includes a first fluid. The system comprises an infusion assembly that includes a catheter having a series of holes distributed around an exterior surface and a pumping system for introducing a second fluid into said catheter to create a solution mixture. A data collection system is provided for collecting data indicative of pressure and conductivity values. Data from the data collection system is forwarded to a data processing and control apparatus. The data processing and control apparatus comprises conversion means for converting the measured conductivity into a concentration value and control means for controlling operation of the infusion assembly based on a comparison of selected values with data received from the data collection system. A user control and analysis system allows user interaction.

Abstract: A processor driven syringe pump for one or more, typically two syringes, which are held vertically in corresponding pumping stations of a housing unit which itself is typically suspended from an IV pole. The pump features a central display having portions corresponding to each of the syringes operated by the pump. A data entry knob cooperative with a display processor, causes a cursor issue on the display to step through and choose the menu selections. A function knob is operative to select five operating states including: Purge, Setup, Stop, Run and Bolus in a virtual or software driven manner. The syringe holding station includes a pusher assembly having plunger clamp assembly and a load cell to measure force exerted on the plunger flange. An actuation pad and associated linkage provides for easy syringe flange capturing, while a syringe barrel clamp provides for easy syringe loading and secure syringe barrel positioning for many sizes of syringe.
