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).
