frequency of ultrasonic wave will reflect when it encounters obstacles during the transmission. If the object is
stationary, the reflected wave frequency is the same as the transmitted wave frequency. Once the object is moving, the
reflection frequency will change, and the greater the movement rate of the object, the greater the change of the
frequency. So we put the ultrasonic probe on the abdomen surface of the pregnant woman. Since the fetal heart beat
has movement relative to the ultrasonic probe, the reflected wave will cause frequency offset after the transmitting
wave encounters the heart, so as to calculate the frequency of the fetal heart beat per minute (fetal heart rate), and so
on. Uterine contraction pressure is to detect the uterine contraction pressure change of the pregnant woman through
uterine contraction probe sensor, and draw the curve. Fetal movement frequency is manually recorded by fetal
movement pen button according to the pregnant women feel their own fetal movement.
Monitoring all stages after pregnancy.
Fetal Monitor is not applicable to monitor water birth.
Intended Usage
It is provided for medical institutions to monitor the fetal heart rate, the fetal movement and uterine contraction
pressure.
Product Composition
It consists of the host and the ultrasonic probe.
1.2. Safety Guide
Classification according to anti-electric shock type and anti-electric shock degree:
JPD-300E is class-II power supply BF type, a mobile ordinary equipment. Classification according to the degree
of protection against liquid inlet: a mobile ordinary equipment. The waterproof grade of the probe is IPX4.
Application part to BF type.
BF-type protection indicates that the patient connection should comply with the stipulation of IEC60601-1 to
allowable leakage current and dielectric strength.
