3.1 System
Overview
Freedom consists of three components: the Ultrasound transducer (SF1-US),
the TOCO transducer (SF1-TOCO) and the Receiver (SF1-EUR or SF1-SL).
There are two receiver models operating at different radio frequencies for
different markets. "SF1-EUR" is for use in regions that use the ISM wireless
standard; "SF1-SL" is for use in regions that use the WMTS wireless standard.
When in use, the TOCO transducer sends signals to the US transducer, which
then transmits both signals to the Freedom receiver unit. The receiver converts
these signals into the required format for input to the attached Fetal Monitor
system. The system monitors two physiological parameters:
- Fetal Heart Rate
- Uterine activity
Key features:
•
Transducers are small, light in weight and water tight
•
Low voltage wireless transmission is safe for use in water
•
No cables gives the patient greater freedom of movement in & out of bed
•
The system is easy for the users to operate
•
The transducers are powered by rechargeable Li-Ion batteries
•
Batteries will automatically recharge when docked with the receiver
Transducers
The transducers contain radio frequency (RF) transmitters. Signals are
transmitted in an ISM or WMTS band according to location and local
regulations. The SF1-EUR (ISM) has 26 channels, and SF1-SL (WMTS) has
100 channels. The range depends on the local conditions. The exact range
of any telemetry system can only be determined by a fi eld test. When the
US transducer is used under water the range will be reduced compared with
transmission in air.
During use the battery capacity of the transducers are monitored. The receiver
has a battery indicator for each transducer consisting of four green LEDs; four
LEDs indicating that the transducer is fully charged. When the battery becomes
discharged the transducer is automatically shut off.
