MS400 Multiparameter Simulator: Portable Color Touch Patient Monitor

The MS400 Multiparameter Simulator is a compact, lightweight testing companion designed to validate and calibrate multiparameter patient monitors directly at the point of use. Built to replicate realistic physiological signals, it covers 12-lead ECG, respiration, temperature, and both 2-channel and 4-channel invasive blood pressure (IBP) waveforms. With its palm-sized form and onboard color touch interface, you can configure, visualize, and export test data anywhere the monitor goes.

What you can simulate

• ECG: precise 12-lead simulations including adult and pediatric signals, and standard calibration signals aligned with ANSI/AAMI EC13-2002, AHA, MIT ECG databases, plus user-defined waveforms stored on a TF card for seamless compatibility with your testing matrix.
• Arrhythmias and pacemaker waves: 35 arrhythmia patterns (Atrial, Ventricular, Premature Beats, Conduction Defects) plus pacemaker modes (Asynchronous, Demand, Atrial/Synchronous, Non Capture, Non Function) to challenge monitors and verify alarm logic.
• Invasive/Non-Invasive Blood Pressure: four-channel IBP simulation with a dynamic default setup (Channel 1–4) to replicate arterial, radial, ventricular, atrial, and catheter-derived pressures, including right heart and pulmonary sites where applicable.
• Respiration: adjustable rate, impedance, and baseline impedance with apnea data to test monitor breathing tracking and alarm thresholds.
• Temperature: four distinct temperature data streams to validate fever and hypothermia alarms and trending.
• Waveforms: configurable square, triangle, pulse, and sine signals with adjustable frequency for calibration of display, timing, and input filtering.
• ECG waveform library: supports a wide range of ECG shapes and features, enabling realistic pacing, artifact scenarios, and morphology changes during testing.

Advanced features that set MS400 apart

• Fully portable with a 3.5" TFT touch screen for intuitive waveform selection and real-time viewing, eliminating the need for external controllers during field testing.
• Two power options: rechargeable lithium battery for true field testing and a linear adapter to minimize electrical noise and interference during bench work.
• Flexible operation modes: use tactile keys or touch screen based on your testing environment or operator preference.
• In-situ testing: designed to be used with the monitor you’re testing, so you can validate performance exactly where the device operates.
• Comprehensive waveform data management: user-defined waveforms stored on a TF card can be displayed by the MS400 and exported to the equipment under test, enabling repeatable, configurable test scripts.

Ideal use cases

This device is purpose-built for biomedical engineers, clinical engineers, quarantine and service centers, and training labs who need realistic, repeatable test signals without removing monitors from patient-care environments. Typical workflows include:

• QA/QC testing of ICU and bedside monitors to validate alarm thresholds, trend accuracy, and waveform fidelity.
• On-site calibration in hospital wards or operating rooms to verify performance under real-world wiring and power conditions.
• Educational demonstrations and hands-on training for clinicians and technicians on ECG interpretation, arrhythmia recognition, and hemodynamic monitoring.
• Software and firmware validation for monitor manufacturers by exercising multiple signal paths and data export routines.

How MS400 improves reliability and efficiency

By combining realistic, database-backed ECG waveforms with flexible IBP, respiration, and temperature simulations, the MS400 reduces the guesswork in monitor validation. Its ability to export calibrated waveforms and to store user-defined data means you can reproduce exact scenarios across multiple devices, ensuring consistency in test results and faster fault isolation when issues arise.

Technical highlights at a glance

• ECG simulation across 12 leads with adjustable amplitude (0.5–2.0 mV) and rate (spanning pediatric to adult ranges up to 350 BPM).
• 35 arrhythmia types including atrial and ventricular variants, plus a comprehensive set of conduction defects.
• Four-channel IBP simulation with full site coverage (artery, radial, left ventricle, right heart sites, and pulmonary parameters).
• Respiration and apnea data with adjustable rate and impedance settings.
• Four temperature data streams for patient monitoring verification.
• Multiple waveform formats (square, triangle, pulse, sine) with selectable frequency.
• ECG calibration signals compatible with major ECG databases and readily exportable to equipment under test.
• TF card storage for user-defined waveforms and easy transfer to test targets.
