Fetal Heart Rate Monitor Home Use Doppler Non-radiation Fetal Movement Stethoscope for Pregnant Women

  【8 Features】 1. Low noise 2. Measurement accuracy 3. High sensitivity 4. Automatic shutdown 5. Backlit large screen 6. Rechargeable lithium battery 7. Autocorrelation algorithm 8. EU CE certification 【Product Description】 1. Fetal heart and fetal movement monitoring during pregnancy can effectively avoid fetal instability due to intrauterine hypoxia. It can easily monitor the changes of fetal heart rate at home and bring the baby a caring guard. 2. The autocorrelation algorithm can effectively eliminate the interference caused by the outside world, suppress the noise in the echo signal, improve the accuracy, reduce the calculation amount, improve the response speed, and ensure the accuracy of the measurement results. 3. The comprehensive sensitivity is 118.5dB, and the high-sensitivity wide-beam 2.5MHz probe can obtain a larger focus area and achieve more uniform coverage at a larger detection range. 4. The use of digital filter noise reduction technology can reduce other noises in the abdominal cavity except for the fetal heart rate, optimize sound processing, reduce background noise, and make the fetal heart clearer. 5. Ultrasonic power per unit area is less than 10mW/cm2, and ultrasonic Doppler detection technology is used to accurately detect changes in the fetal heart rate while reducing adverse effects on the fetus. 6. The 1.8-inch backlit large-screen LCD display makes the reading clearer, convenient and more worry-free. Press the power button in the boot state to switch the display without backlight. 7. Detachable rechargeable lithium battery, which can be charged once and can work for 6 hours. 8. Two listening methods: (1) Headphone listening to avoid external noise interference and easier to accurately monitor the fetal heart sound; (2) Amplification sharing, which can share the baby's heartbeat rhythm with family members. 9. High-fidelity speaker: low-power design, adjustable volume. 10. Automatic shutdown: automatic shutdown in 2 minutes, economical and energy-saving. 【Instructions】 Step 1: Press the switch button to turn on the instrument. Step 2: Apply coupling agent on the probe. Step 3: Move the probe to find a suitable fetal heart position (please contact the probe directly with the skin) 【Precautions】 1. After hearing the fetal heart sound, you must continue to move the probe to find a clear, loud, and rhythmic position. After finding the position, the probe will not move. The fetal movement displayed after 3-5 seconds is the accurate fetal heart rate. 2. When measuring fetal heart rate, pregnant mothers should lie flat or half-lying, keep their mood calm, measure in a quieter environment, and move as little as possible.
