6. When applied to the patient, the wireless ultrasound transducer may warm
slightly (less than 3°C (5.4ºF) above ambient temperature). When NOT applied,
the wireless ultrasound transducer may warm slightly (less than 3°C (5.4ºF)
above ambient temperature).
7. The US-T transducer taken up first displays US1 on the screen, and the one
taken up later displays US2. Please do not take two US transducers
simultaneously and wait 2 seconds to take the other one. Restart the transducers
if you take up two US-T transducers at the same time by mistake.
8. Please apply coupling gel to the US-T transducer before use and move the
transducer to get the desired fetal heart and belt it to the belly. Underwater
monitoring requires less coupling gel or no coupling gel. The TOCO-T transducer
and TOCO-E transducer can be applied to the belly directly without coupling gel.
9. Excessive coupling gel may slide the transducer.
10. The TOCO-E transducer monitors DECG or MHR only when it is connected with
the DECG or MECG cable. If the TOCO-E transducer is not connected with the
DECG or MECG cable, it only monitors TOCO. Besides, the DECG cable and the
MECG cable cannot be connected to the TOCO-E transducer at the same time.
11. When using the TOCO-E transducer to monitor DECG or MHR, it is
recommended that the DECG cable or the MECG cable be kept straight to avoid
damage to the TOCO-E transducer’s interface caused by twisted cable.
3.3.4 Relocation of the Transducers
Transducers may be belted on the patient for a long time without stop. In rare cases, this may
lead to irritations to the patient skin. To avoid skin irritations, please inspect the application site at
least every half an hour. If the skin quality changes, you should move the transducer to another
site.
US transducers need to change application site frequently to track fetal heart. It is normal
during a monitoring process. But TOCO transducers are different. Please periodically inspect the
application site (between contractions) of TOCO transducer at least every half an hour.
To reduce the risk of skin irritations, do not allow residual cleaning agent or disinfecting
agent on the surface of transducers. Before using cleaning agent and/or disinfecting agent, refer to
the cleaning and disinfecting sections in this user manual. Wipe the transducer surface with a
cloth dampened with water before applying to the patient.
3.3.5 Monitor the Ambulatory Patient
FTS-3 is suitable for ambulatory patients. You can take out the transducer from the docking slot
and fix the transducer on the location where the best fetal heart signal is received.
Please pay attention to the following during the monitoring.
Ensure the transducer is tied up well.
Record the effective FHR.
