94v0circuitboard for maternal and child monitor
Applications: maternal and child monitors, pulse oximeters, fetal heart monitors, electronic colposcopy, patient monitors, multi-parameter monitoring devices, etc.
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 .
