Profile: Pronk Technologies Inc. specializes in diagnostic tools. We develop signs monitors and patient simulators. We also offer pulse oximeter simulator and non invasive blood pressure stimulator. Our pulse oximeter simulator provides four levels of simulated saturation, three heartrates and two perfusion levels. The OxSim Pulse Oximeter Simulator provides four levels of simulated saturation (85, 95, 98, and 99 percentage), three heartrates (80, 40, and 140 Bpm), and two perfusion levels (normal & low). The OxSim simulations are designed to produce simulated values within the specified tolerance of both durable and disposable Oximeter sensors. It operates for 8 hours on a single AA battery or on included AC adapter. The OxSim conserves battery power by going to sleep mode if it does not see a sensor for 10 minutes. The OxSim is compatible with the battery boost option, which makes it convenient to use with a SimCube simulation kit. The OX-1 comes with a small 6VDC/2 amp power supply, a carrying case and an AA battery.
