Portable SpO2 simulator medical simulator Oxygen saturation simulator

The SpO2 Blood Oxygen Simulator is a high-accuracy medical test instrument engineered for comprehensive calibration, performance verification, and functional testing of pulse oximeters, patient monitor SpO2 modules, and SpO2 sensors across diverse clinical and laboratory environments. Designed as a professional-grade reference standard, this advanced simulator generates precise, repeatable optical and electronic signals that emulate real physiological photoplethysmographic (PPG) conditions, enabling biomedical engineers and clinical technicians to validate SpO2 measurement accuracy, assess sensor performance, and ensure compliance with international medical device standards (IEC 60601-2-61, ISO 80601-2-61). Featuring both optical simulation via a simulated human "finger" test interface and direct electronic simulation modes, this versatile instrument supports testing of SpO2 saturation values (70%–100%), pulse rates, modulation depth, and light transmission conditions. The simulator's embedded multi-manufacturer R-curve library accommodates the diverse R-curve algorithms implemented by different pulse oximeter brands, ensuring accurate simulation across the full clinical measurement spectrum. Additional test capabilities include sensor probe integrity verification (short-circuit, continuity, open-circuit, and LED functionality testing), making this compact, portable instrument an essential reference tool for preventive maintenance and quality assurance programs.

Specification and operation instruction

This SpO2 simulator is extensively deployed across Biomedical Engineering Departments, Clinical Engineering Labs, Hospital Maintenance Workshops, Medical Device Manufacturing Facilities, and Metrology Calibration Centers where pulse oximeters and patient monitors require periodic calibration, performance verification, and regulatory compliance testing. It serves as an essential reference instrument for biomedical technicians, enabling comprehensive validation of patient monitors and pulse oximeters from leading manufacturers (GE, Ph, Dräger, Mindray, Nihon Kohden, etc.) across Intensive Care Units (ICUs), Emergency Departments, Operating Theaters, General Wards, and Neonatal Intensive Care Units (NICUs). The simulator's multi-condition testing capabilities make it particularly valuable for algorithm performance assessment, sensor/probe quality verification, clinical traceability programs, and device training—supporting quality assurance workflows that ensure SpO2 monitors maintain measurement accuracy throughout their operational lifespan. Its portable, battery-powered design supports both bench-top calibration workflows and on-site preventive maintenance across diverse clinical departments.
