    Area of Science:

    • Biomedical Engineering
    • Medical Device Technology

    Background:

    • Infusion pumps are critical for administering fluids and medications.
    • Air in infusion lines can lead to serious patient complications.
    • Existing air detection methods may have limitations with different fluid types or administration sets.

    Purpose of the Study:

    • To develop a universal air-bubble detector for drip-controlled infusion pumps.
    • To enhance patient safety by providing a reliable air-in-line alarm facility.

    Main Methods:

    • Utilized modulated infra-red radiation transmission.
    • Detected variations in peak intensity caused by air gaps or bubbles.
    • Tested with clear and opaque fluids in standard solution administration sets.

    Main Results:

    • Successfully developed a universal air-bubble detector.
    • The device detects air bubbles in both clear and opaque fluids.
    • Compatible with most standard infusion administration sets.

    Conclusions:

    • The developed air-bubble detector is a versatile and effective safety upgrade for infusion pumps.
    • It offers a small, lightweight, and inexpensive solution for air-in-line detection.
    • Enhances infusion pump safety across a wide range of clinical applications.
