Figure 3-5. Model 174 Connectors
Combi-Connector (Primary Ultrasound or FECG)
The combi-connector is a blue connector
*
with a dark grey inner center. This round
receptacle is mechanically keyed to accept only a Corometrics ultrasound transducer
plug or a Corometrics FECG cable/legplate plug. The fetal heart rate derived from
this transducer or cable/legplate shows in the primary fetal heart display.
IMPORTANT
COMBI-CONNECTOR—The combi-connector can be used for
monitoring ultrasound or FECG depending on what you plug in
(US transducer or FECG cable/legplate). When used in
conjunction with the secondary ultrasound connector, you have
the option of monitoring twins using dual US or FECG/US.
Secondary Ultrasound Connector
The secondary ultrasound connector
*
is a blue, round receptacle mechanically keyed
to accept only a Corometrics ultrasound transducer plug. The fetal heart rate derived
from this connector shows in the secondary fetal heart rate display.
Uterine Activity Connector
The uterine activity connector is a white, round receptacle mechanically keyed to
accept a Corometrics tocotransducer, a Corometrics strain gauge transducer plug, or
any intrauterine pressure catheter with compatible cable plug. The uterine activity
value obtained from this transducer shows in the uterine activity display.
*
If the Model 174 is interfaced to a central information system (CIS), be aware that the CIS may be
designed to alarm when there is no fetal heart rate signal. Therefore it is recommended that you
unplug the ultrasound and/or FECG transducers from the monitor, when not in use, to eliminate false
alarms.
