System for monitoring and controlling pressure and concentration values in a fluid conduit

摘要

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. The system allows complete automatic control over the fluid distribution within a fluid conduit in response to measured values.
