    Area of Science:

    • Biomedical Engineering
    • Hematology
    • Medical Devices

    Background:

    • Accurate and rapid coagulation assessment is crucial for patient management.
    • Existing methods may require complex procedures or large sample volumes.
    • A need exists for simple, continuous bedside coagulation monitoring.

    Purpose of the Study:

    • To introduce a new continuously recording bedside coagulation screening device.
    • To describe the working principle and capabilities of the impedance machine.
    • To present clinical and experimental applications of the device.

    Main Methods:

    • The impedance machine measures mechanical impedance changes during fibrin formation.
    • It utilizes a minutely vibrating probe interacting with the specimen.
    • The device operates with small volumes (0.04-0.4 ml) of whole blood or plasma.

    Main Results:

    • The instrument provides continuous recordings of the coagulation process.
    • Real-time observation of fibrin formation is possible via transillumination.
    • The device demonstrated simplicity in handling and operation.

    Conclusions:

    • The impedance machine is a user-friendly, continuously recording bedside device for coagulation screening.
    • Its minimal sample requirement and disposable components enhance its clinical utility.
    • The device shows promise for both clinical and experimental coagulation analysis.
