Operation; Temperature Control System - Hitachi MXS1 Instruction Manual

4. Operation

Place the ultrasonic radiation part of the probe onto the skin surface. An image of the region of interest is displayed
on the monitor of the ultrasound diagnostic instrument. For details on displaying and adjusting the image, refer to the
documentation supplied with the ultrasound diagnostic instrument.
Caution
Do not operate the probe with excessive force.
Use with excessive force could result in injury to the patient.
Scan for minimum time necessary at the lowest possible acoustic output.
Acoustic output may affect the patient's internal tissues.
For details about the acoustic output, please refer to the documentation supplied with the ultrasound
diagnostic instrument.
Do not touch the connector terminal pin of the probe.
Electrostatic discharge may result in malfunction of the probe.
Do not touch the probe connector of the ultrasound diagnostic instrument and the patient at the same
time. It can cause electric shock to the patient.
Remove the probe after pushing the Freeze button
Probe will be damaged when do not remove the probe after stopping the transmission.

4-1. Temperature Control System

The tip of the probe contains a temperature sensor. This sensor monitors the surface temperature at the tip of the probe
in order to prevent damage to the body surface.
When the surface temperature exceed limit, the message appears on the equipment monitor.
1) When the surface temperature becomes 41°C
When the surface temperature becomes 41°C, the message
equipment monitor.
2) When the surface temperature becomes 43°C
When the surface temperature becomes 43°C, the message
appears on the equipment monitor and the acoustic output is automatically stopped. When surface temperature is below
40.5°C, This message disappears and restarts operation.
3 Under the following conditions, the probe tip gets hot easily and rapidly, so select "Saving".
The ambient temperature exceeds 30°C.
Patient has a high body temperature.
Prolonged use is expected.
See the equipment mannual for the detail.
"Probe temperature is higher than
"TTE thermal limit. Auto cooling mode in
-7-
MN1-6260 Rev.2
41.0°C." appears on the
progress."
