Chapter 1: Product Description
Product Denition
The Mini Telemetry System includes receiver and transmitter. It provides a wireless means of transmitting heart
rate and uterine activity signals from an ambulatory
1
mother to a fetal or maternal/fetal monitor. The system
operates with the following Corometrics brand monitors:
• 120 Series
• 170 Series
• 250 Series
• 250cx Series
The transmitter is also sold separately, it is compatible with 340 telemetry receiver. All the connections remain
the same.
NOTE: The operator will identify fetal movements with the MARK button instead of the automatic fetal movement
detection support of the fetal monitor system. The system monitors fetal heart rate through ultrasound doppler
technology, ECG (FECG or MECG), and uterine activity (TOCO or IUPC) signals individually or in combination—
depending on the available parameter in the fetal or maternal/ fetal monitor. Refer to your monitor’s operation
manual as needed.
Indications for Use
The Mini Telemetry system is intended to transmit fetal heart rate and uterine activity signals from an ambulatory
mother to a fetal or maternal fetal monitor during the ante partum period and during labor. The system allows
ultrasound fetal heart rate, FECG, MECG and uterine activity signals to be monitored individually or in combination.
The Mini Telemetry system is intended for use under the direct supervision of a licensed healthcare practitioner
in a dened coverage area.
The Mini Telemetry device is not intended to be operated in mobile vehicles including ambulances or other
vehicles associated with health care facilities.
