الوصف
The product is mainly
used to detect the fetal heartbeat rate (FHR) and
the sound of the fetal heartbeat (SFH).
The growth and development of a fetus
can be found out through examination of
these indices. It is applicable for department of
gynaecology and obstetrics and clinic daily
Fetal Doppler consists of probe (transmitter and receiver) and
signal
process
unit.
Ultrasonic wave is transmitted from one piezoelectric ceramic at
the front of
the probe to the uterus of the pregnant
women. Echo is received by the
other piezoelectric ceramic at the front of
the probe when ultrasonic wave
reaches the fatal heart. Then it is
converted into voltage. This Doppler signal
is detected and demodulated from the
received signal. And the Doppler
frequency is consistent with the rhythm of
the fetal systole and diastole.
Once cardiac valves vibrate and a Doppler
frequency excursion is formed. It
is transmitted an output signal of cardiac
valves vibrating, and it is sent to
the loudspeaker for getting a rhythmical
sound with the fetal heartbeat.
Simultaneously, it is sent to a counter
which calculate periods of heartbeat
that is fetal heartbeat rate (bpm=beat
per minute).
