    Area of Science:

    • Biomedical Engineering
    • Medical Device Development
    • Patient Safety Technology

    Background:

    • Venous needle dislodgement (VND) during hemodialysis is a critical complication.
    • Accidental needle removal from grafts or fistulas can cause severe hemorrhage and potentially fatal blood loss.

    Purpose of the Study:

    • To develop and evaluate a novel Arduino-based device for detecting venous needle dislodgement.
    • To assess the device's efficiency in identifying VND within a critical 12-second timeframe.

    Main Methods:

    • Development of a prototype VND detection system utilizing Arduino technology.
    • Rigorous testing of the device through four distinct experimental protocols.
    • Application of statistical analysis to evaluate detection accuracy and speed.

    Main Results:

    • The Arduino-based VND detector demonstrated high efficiency in identifying needle dislodgement.
    • Successful detection of VND events was consistently achieved within the target 12-second window.
    • Statistical analysis confirmed the reliability and effectiveness of the developed device.

    Conclusions:

    • The novel Arduino-based device offers a promising solution for real-time VND detection.
    • This technology has the potential to significantly enhance patient safety during hemodialysis.
    • Early detection of VND can prevent serious complications and improve treatment outcomes.
