Crow, the Valimed unit as it exists right now obviously cannot monitor an IV bag or metering pump. " have not conceded that it can monitor a drip "in situ" on the IV pole. WHY?? Because the sample has to be placed in a cuvette and put inside the isolation chamber inside Valimed." If there is a demand for that application, CDEx will have to develop special bags/containers to monitor the liquids, before or after compounding. The main Valimed unit would have to be remote and (ideally) be capable of monitoring several samples at once. Maybe even wireless remote. Any signal interference would have to be isolated by design. That's the positive spin. The negative spin- it will never work! LOL
