How To Use Doppler Fetal Heart Rate Monitor?

Before use, check whether the fetal heart rate monitor is damaged or abnormal, and connect the power supply by installing the battery or plug. The plug must only be inserted into a power socket that meets the power requirements. Apply an appropriate amount of ultrasonic coupling agent evenly on the acoustic surface of the ultrasonic probe. Aim the ultrasound probe at the location of the fetal heartbeat in the pregnant woman's abdomen, and adjust the probe position and angle appropriately until you hear the clearest and loudest fetal heartbeat sound. Appropriately adjust the position and angle of the probe until you hear the clearest and loudest fetal heartbeat sound. You can adjust the volume as needed and wear headphones to listen to the fetal heartbeat sound. Record the fetal heart rate value, and determine the fetal vital signs and fetal health status through numerical changes, speed changes, irregular changes, etc. After the work is completed or the instrument has been left for too long, the power should be turned off or automatically shut down, general garbage and medical waste should be disposed of, and the test results should be recorded.
