Switching Off
Touch the On/Off touch key for about 1second when the Doppler is on,

If the Doppler is not in operation or no signal is received for 2 minutes, the
Doppler will switch off automatically.
FHR Monitoring
Before applying the Doppler to inspect FHR, you should always check
whether the Doppler is in good condition and whether there is evident
damage that might affect patient‘s safety and the device‘s function.If
damage that might affect patient‘s safety and the device‘s function.If
evident damage is found, stop using it at once and replace it with a good
one.
Procedures to Monitor FHR:
a)
Have the patient lie on her back.
b)
Apply
appropriate
amount of coupling gel
to
the

How to Find the Best FH Signal:
1)
The easiest way: take the position the doctor last monitored for FHR
as a reference and move the Doppler around the position slowly
until the best FH signal is found.
2)
The fetal heart position may change as the fetus moves inside the
uterus. You can confirm the fetal position first according to the
position of the uterus fundus in different gestational weeks.
The clearest and loudest fetal heart sound is generally obtained
when the Doppler is placed on the fetus‘s back. Fetal movement is
usually the movement of fetal limbs. So, if frequent fetal movement
occurs at the right side of the abdomen, the fetus‘s back is
probablyat the left sideand vice versa.You can find the fetus‘s back
according to fetal movement‘s position.
If the fetus is in cephalic delivery position, the fetal heart is either on
the right side or on the left side below the navel; if the fetus is in
breech delivery position, the fetal heart is either on the right side or
on the left side above the navel.

Note:
1 The best quality of fetal heart signal is obtained only when the Doppler
is placed on the best monitoring position.
2 Do not place the Doppler near positions where placental sound or
umbilical blood flow sound is loud.
3 If the fetus is in the cephalic position and the mother is supine, the
clearest heart sound will normally be found on the midline below the
navel. During monitoring, the pregnant woman‘s prolonged lying in
the supine position should be avoided to reduce the possibility of
supine hypotension. Putting a pillow or cushion under the patient‘s
head or feet can be of help.

signal is detected. If the calculated FHR is not in accordance with the

Maintenance and Cleaning
Maintenance
Before each use, check if the equipment has visible evidence of damage
that may affect the patient and the operator‘s safety or the Doppler‘s
that may affect the patient and the operator‘s safety or the Doppler‘s
functioning. If the damage is evident, contact the manufacturer for service
or replace it.
The overall check of the Doppler, including safety check and function
check, should be performed by qualified personnel every 12 months, and
each time after service. And safety check must include current leakage test
and insulation test. Besides the above requirements, comply with local
regulations on maintenance and measurement.
The accuracy of FHR is determined by the Doppler and cannot be adjusted
by user. If you have doubt concerning the accuracy of FHR, verify it with
other methods such as using a stethoscope, or contact local distributor or
the manufacturer for help.
The Doppler is frangible and must be handled with care.Wipe the
remaining gel off the Dopplerafter each use. These measures can help
prolong the Doppler‘s life.
Replace the accessories such as the battery according to use. If any of the

Replace the accessories such as the battery according to use. If any of the
accessories are damaged, refer to chapter Ordering Information for
details and order new ones.
Please check the label for the date of manufacture, the service life is 5
years (The service life is limited to the Doppler, not including the
replaceable accessories. The only replaceable accessory of SD1 is battery.
The frequency of usage is 8 hours/day).
Cleaning
Before cleaning, switch off the Doppler.
Keep the exterior surface of the device clean and free of dust and dirt.
