GE Corometrics 170 Series Fetal Monitors Features Whether you perform antepartum fetal monitoring in an office setting or in the hospital, Corometrics* 170 Series Fetal Monitor can help. You can trust our fetal monitors to help you improve the standard of care for your expecting mothers. We designed these compact, lightweight monitors to help you effectively and efficiently care for mom and baby by accurately and noninvasively tracking baby’s heart rate for non-stress tests. The 170 series is used with our Nautilus* watertight and lightweight Toco and 9-crystal Ultrasound transducers for comfortable and reliable monitoring. Alerts you to fetal heart rate concerns - The fetal heart rate alarm provides both audible and visual alerts if the heart rate is higher or lower than the range you set as normal Helps you place the transducer - Independent volume controls make it easier to locate the transducer for most effective monitoring Can monitor multiple heart rates - There is an option to monitor twins Displays important information prominently - The large, easy-to-read LCD display clearly presents information about fetal heart rate and uterine activity Offers portability - An optional mobile roll stand cart lets you transport the monitor and all of its necessary accessories GE Corometrics 170 Series Fetal Monitors Specifications Dimensions Height x Width x Depth: 14.6 x 42.5 x 25.4 cm (5.75 x 16.75 x 10 in) Weight: 3.6 kg (8 lbs) approximately Power Requirements Nominal line voltage: 100-230 VAC Line frequency: 50/60 Hz (operates over 47-63 Hz) Power consumption: ≤30 VA Monitor DC input: 12 Vdc at 2.5A Operating Specifications Technique Pulsed Doppler with auto correlation processing Transducer Type 9-crystal Pulse Repetition 2 kHz (all modes) Frequency Pulse Duration 92 μs Transmitter Frequency 1.151 MHz Spatial-Average Temporal Isata <5 mW/cm2 Average Intensity Focal 20 dB Beam Area 16.6 cm2, at a range = 7 cm Peak Instantaneous 1.8 mW/cm2 Intensity Heart Rate Counting Range 50-210 BPM Leakage Current Complies with IEC 60 1.1 and/or IEC 601.1.1 harmonized national standard; Complies with EN 60601-1-2:2002 FECG Mode Technique: Peak detecting, beat-to-beat cardiotachometer Heart range counting range: 30-240 BPM Heart rate resolution: 1 BPM Artifact elimination: service selectable, ±25 BPM artifact rejection Countable input signal range: 15µV to 2mV peak-to-peak Offset voltage tolerance (differential): ±300 mVdc maximum Maximum common mode voltage: 20V peak-to-peak Common mode rejection: Balanced: >120 dB at mains frequency, with patient cable, Unbalanced 5kΩRA or LA: >110 dB at mains frequency Input impedance: Differential: >10MΩ; Common mode: >20MΩ Mains frequency rejection: >40 dB Leakage current: complies with IEC 601.1 and/or IEC 601.1.1 harmonized national standard Isolation, mains-to-patient: >5656 Vdc Ultrasound Mode Technique: pulsed Doppler with autocorrelation processing Transfer transducer type: 9-crystal Pulse repetition frequency: 2 kHz (all modes) Pulse duration: 92 µs Transmitter frequency: 1.151 MHz Spatial-Average temporal average intensity: Isata<5 mW/ cm² Focal 20 dB beam area: 16.6 cm², at a range = 7 cm Peak instantaneous intensity: 1.8 mW/cm² Heart rate counting range: 50-210 BPM Leakage current: complies with IEC 601.1 and/or IEC 601.1.1 harmonized national standard
