Hemostatic system and components for extracorporeal circuit

A method for monitoring and regulating blood parameters in the course of extracorporeal blood flow, the method comprising:

• a) providing an extracoporeal blood flow circuit comprising, in the order of blood flow, a reservoir, a pump, and oxygenator, a filter, together with associated tubing, connectors and controls,
• b) providing a system comprising
• i) one or more automated sensor modules adapted to monitor, directly or indirectly, the presence of one or more blood parameters, and
• ii) one or more regulating modules adapted to affect the presence, concentration and/or activity of one or more blood parameters.
• c) employing the sensor module(s) to monitor one or more blood parameters, and
• d) employing the filter module(s) to affect the presence, concentration and/or activity of one or more blood components, wherein the system comprises at least one sensor module that is adapted to incorporate flow injection analysis (“FIA”) techniques, and that comprises:
• i) a blood withdrawal component with in-line access, ii) an analytical component, and iii) a readout component.
