  • Patent number: 4650464
    Abstract: The infusion of intravenous fluid into a patient is indirectly measured by monitoring the decreasing weight of an intravenous fluid receptacle as fluid flows from the receptacle to the patient. The method hereof includes the steps of taking a plurality of samples of the weight of the receptacle, calculating the difference between succeeding weight samples, comparing the weight difference against predetermined quality control criteria, taking additional samples if the criteria are not met, and converting the weight loss difference into volume of fluid infused into a patient. The apparatus hereof includes a transducer for sensing the weight of the fluid containing receptacle, circuitry for converting the analog signal generated by the transducer into a digital electronic electrical signal, and a processor for calculating the volume infused into a patient as a function of the sensed weight of the receptacle.
