3. The maternal and child monitor is a sensor for mother and baby to monitor physiological data. It can sense various physiological changes, magnify the enhanced information, convert it into electrical information, and then calculate and edit the information. If the specified indicator is exceeded, the alarm will be triggered. system. Mother-infant monitors have different functions, and their specific working principles are different, but generally they sense various physiological changes through sensors, and then the amplifier will strengthen the information and then convert it into electrical information. At this time, the data analysis software will calculate the data.Analyze and edit, and finally display the function modules in the display, or record them according to the needs, print them down, when the monitored data exceeds the set indicators, it will activate the alarm system and send a signal to the attention of the medical staff.

A maternal and child monitor is an instrument that monitors both mother and baby for physiological data.

1. Mother monitor: heart rate, heart, breathing, body temperature, blood pressure, blood oxygen.

2. Baby monitor: fetal heart rate, uterine contraction pressure, fetal movement.

The parameters measured by the maternal and fetal monitors are fetal heart rate, uterine contraction pressure, fetal movement, maternal blood pressure, blood oxygen, pulse, ECG, respiration, body temperature etc. Then, it is converted into an electrical signal with a certain functional relationship, and then recorded and displayed by amplification, filtering, calculation, processing etc. Therefore, the sensor is a key component. The sensitive and converting elements in the sensor are in turn the components that directly sense or respond to measurements that are converted into electrical signals. For example, a thermistor that senses body temperature, a sensor diaphragm that infects blood pressure detection, etc., are sensitive components. Conversion components such as phototubes in blood oxygen saturation, bridges in respiratory measurement, etc.; signal conditioning and conversion circuits process, amplify, convert, and convert electrical signals output by the sensor elements into convenient microprocessor circuits or display, recording circuit processing signal .
