Flow metering apparatus for a fluid infusion system

摘要: A system for infusing fluids into the human body includes a peristaltic-type metering apparatus which controls flow of fluid through disposable administration set. The control allows volume and rate to be infused accurately preset by operator. provides an alarm function in event malfunction pump or occlusion tubing set, minimum pumping maintaining after desired has been infused. Novel power supply circuitry within renders immune line transients, novel bubble detector circuit more reliable detection air bubbles tubing. mechanical linkage between pressure plate downline restriction plunger convenient loading set automatic closure prior use.
