    Summary

    The Quest/Cutter Infusor demonstrated the highest accuracy among five gravity-feed infusion devices. Volumetric devices generally outperformed nonvolumetric ones, with Quest/Cutter requiring no special adjustments for accuracy.

    Area of Science:

    • Medical Devices
    • Biomedical Engineering
    • Fluid Dynamics

    Background:

    • Accurate medication delivery is critical in healthcare.
    • Gravity-feed infusion devices are widely used but vary in precision.
    • Evaluating the accuracy of these devices under different conditions is essential.

    Purpose of the Study:

    • To compare the accuracy of five different gravity-feed infusion-control devices.
    • To assess device performance across various flow rates, solutions, and head heights.
    • To identify the most accurate infusion control device for clinical use.

    Main Methods:

    • A gravimetric method was employed to measure accuracy.
    • Five devices were tested: two nonvolumetric (IVAC 230, IMED 350) and three volumetric (Quest/Cutter Infusor, Anatros Rateminder, IVAC 260).
    • Testing occurred at four flow rates (10-250 ml/hr) with different solutions and head heights (30, 100 cm).

    Main Results:

    • The Quest/Cutter Infusor exhibited the lowest mean error rate (0.7%), showing the highest accuracy.
    • Volumetric devices (Quest/Cutter, Anatros Rateminder) were more accurate than the IVAC 260.
    • Nonvolumetric devices (IVAC 230, IMED 350) showed higher error rates and required adjustments for accuracy.

    Conclusions:

    • The Quest/Cutter Infusor is the most accurate gravity-feed infusion control device evaluated.
    • Newer volumetric devices offer high accuracy without needing conversion charts or fluid code selection.
    • Careful selection of infusion devices and understanding their limitations are crucial for patient safety.
