ACCESSORIES (TRANSDUCERS AND CABLES)
The ultrasound transducer, TOCO transducer, and fetal remote marker are connected to
the front panel of the monitor. Each cable has a corresponding tab located on the con-
nector housing to ensure proper insertion into the appropriate socket on the monitor.
Ultrasound Transducer
A multi-crystal, broad beam ultrasound transducer is used to monitor fetal heart rate
(FHR). The ultrasound transducer operates at a frequency of 2.0MHz. Place the FHR
transducer on the maternal abdomen to transmit the low-energy ultrasound wave to the
fetal heart, and receive the echo signal from it.
The main information on the label is as follows:
1. PM 2.0: P means pulsed wave, M means multicomponent. 2.0 means central frequency
is 2.0 MHz.
2. A1: Version number for the ultrasound transducer.
3. DO NOT IMMERSE IN WATER, CLEAN WITH SOAP AND WATER ONLY (the CAUTION
message).
TOCO Transducer
This transducer is a tocotonometer whose central section is depressed by the forward
displacement of the abdominal muscles during a contraction. It is used for assessment of
frequency and duration of uterine contractions. It gives a subjective indication of con-
traction pressure.
The main information on the label is as follows:
1. A1: Version number for the TOCO transducer.
2. DO NOT IMMERSE IN WATER, CLEAN WITH SOAP AND WATER ONLY (the CAUTION
message).
Remote Patient Marker
The remote marker cable, shown at right, is inserted
into a socket at the front panel. The remote marker
is a hand-held switch operated by the patient. The
mother is normally instructed to push down this
switch when feeling a fetal movement.
