    Continuous flush devices are suitable for vascular catheters but show unreliable flow rates for drug infusions or intracranial pressure monitoring. Further research is needed for precise applications.

    Area of Science:

    • Medical Devices
    • Fluid Dynamics
    • Critical Care Medicine

    Background:

    • Continuous flush devices are essential for maintaining patency in vascular access.
    • Accurate flow rate control is critical for specific medical applications, including drug delivery and pressure monitoring.

    Purpose of the Study:

    • To evaluate the reliability of flow rates and ease of use of six continuous flush devices.
    • To determine the suitability of these devices for various clinical applications.

    Main Methods:

    • Comparative analysis of six different continuous flush device makes.
    • Assessment of flow rate reliability and device usability.

    Main Results:

    • All tested devices were deemed appropriate for flushing vascular pressure monitoring catheters.

  • Flow rates demonstrated significant variability, rendering them unsuitable for precise drug infusions.
  • The variability also made devices inappropriate for flushing intracranial pressure monitoring systems.

    • Conclusions:

    • Continuous flush devices are adequate for basic vascular catheter maintenance.
    • Current devices exhibit limitations in flow rate accuracy for critical applications like drug infusion and intracranial pressure monitoring.
    • Device performance needs improvement for enhanced clinical utility in high-precision scenarios.
