The Fluke Biomedical Impulse 4000 (originally developed by DNI Nevada / Dynatech Nevada, also referenced as TQA-9 Mod) is a professional-grade defibrillator and external pacemaker analyser designed for biomedical engineers and clinical equipment testers.
The Impulse 4000 allows users to perform comprehensive safety and performance testing on defibrillators and external pacemakers in accordance with IEC and AAMI standards. It is widely used in hospital biomedical departments, service laboratories, and medical equipment rental and repair organisations.
Key features and capabilities:
• Defibrillator energy measurement for both monophasic and biphasic waveforms
• Waveform capture and display for detailed defibrillator output analysis
• External pacemaker testing including rate, pulse width, amplitude, and refractory period
• Peak voltage and current measurement
• Patient load simulation
• Large backlit display for ease of use in various lighting conditions
• Lightweight and portable design for field and bench use
Typical Specifications:
Energy Measurement Range: 0.5 to 450 J
