Hardware acceleration for real time simulation of physiological systems.

Area of Science:

• Biomedical Engineering
• Medical Device Technology
• Physiological Modeling

Background:

• Medical device testing, particularly for critical devices like pacemakers, is essential due to potential life-threatening consequences of malfunction.
• Thorough testing under both normal and faulty conditions is crucial but often constrained by project budgets.
• Existing testing methods may not offer sufficient depth or cost-effectiveness for comprehensive device evaluation.

Purpose of the Study:

• To introduce a novel real-time digital simulator (DRTS) designed for the comprehensive testing of medical devices.
• To demonstrate the simulator's capability to model physiological systems in real-time for medical equipment interfacing.
• To present a cost-effective solution for enhancing the thoroughness of medical device testing.

Main Methods:

• Development of a real-time digital simulator (DRTS) capable of running physiological system models.
• Integration of Analog-to-Digital (A/D) and Digital-to-Analog (D/A) cards for interfacing simulation outputs with actual medical equipment.
• Real-time simulation of organ or organ group physiological behavior for dynamic testing scenarios.

Main Results:

• The DRTS successfully simulates physiological systems in real-time, providing a dynamic environment for medical device testing.
• The A/D and D/A interface allows seamless integration of simulation data with external medical devices.
• The simulator facilitates in-depth testing of medical devices without significant increases in overall project costs.

Conclusions:

• The developed DRTS offers a viable and cost-effective solution for rigorous medical device testing.
• This approach enhances the ability to test device behavior under various conditions, improving safety and reliability.
• The DRTS technology supports thorough pre-market evaluation of medical equipment, contributing to patient safety.
