    A low-cost microcomputer system provides instant analysis of clotting parameters from a thrombelastograph (TEG). This real-time data collection and reduction enables rapid patient monitoring and improved clinical decision-making.

    Area of Science:

    • Biomedical Engineering
    • Clinical Pathology
    • Medical Instrumentation

    Background:

    • Thrombelastography (TEG) is crucial for assessing hemostasis.
    • Real-time analysis of TEG data can significantly improve patient management.
    • Existing systems may lack efficiency or cost-effectiveness for widespread use.

    Purpose of the Study:

    • To develop a cost-effective, real-time data acquisition and processing system for a three-channel electronic-readout thrombelastograph.
    • To enable instant computation of critical clotting parameters.
    • To facilitate rapid analysis and monitoring of patient coagulation status.

    Main Methods:

    • A small-size, low-cost microcomputer utilizing an Intel 8080 microprocessor was employed.
    • Custom computer hardware was designed for optimized signal sampling, processing, and data storage.
