Clinical overview
The Defi 9 is a professional-grade emergency defibrillator monitor designed for rapid cardiac response in hospitals, emergency departments, clinics, and first aid environments. It combines manual and synchronized defibrillation modes with biphasic and monophasic waveform options, ensuring flexibility in treating various cardiac arrhythmias. The device delivers energy with ±1% accuracy across a wide range (0.3–360 joules), with maximum charging time of 8 seconds to full capacity.
Integrated multi-parameter patient monitoring provides real-time assessment of ECG (12-lead capability), SpOâ‚‚, non-invasive blood pressure (NIBP), respiration rate, pulse rate, and temperature on a large 7-inch TFT display. The system supports adult, pediatric, and neonatal patient populations with appropriate sensor and cuff options. Dual battery system ensures extended operational capacity for continuous emergency response.
