1. Introduction
1.1 General
The EUP-L73S is a linear array probe.
The acoustic output of the EUP-L73S was measured according to
the IEC60601-2-37 standard and the measurement was conducted
by operating with the Hitachi ultrasound diagnostic scanner.
The measured acoustic output is listed in the instruction
manual of the Hitachi ultrasound diagnostic scanner.
The EUP-L73S is categorized in class IIa according to
Directive 93/42/EEC and classified as type BF according to IEC
60601-1.
1.2 Principles of operation
This probe and the ultrasound diagnostic scanner enable image
diagnosis using ultrasonic waves. This system operates under
the principles described below.
1) When an electric pulse signal is applied from the
transmitter to the transducer of the probe, the transducer
converts electric signals into mechanical vibration
energy for emitting pulse-shaped ultrasonic waves into the
body part, liquid or other medium contacting the
transducer.
2) The emitted ultrasonic waves are reflected by boundaries
with different acoustic characteristics (acoustic
impedance) within the body.
3) The transducer is also used to receive reflected
ultrasonic waves. The transducer vibrates mechanically
due to the received ultrasonic waves and converts
mechanical vibrations into electric energy. Electric
signals are converted to shades of brightness by
brightness modulation to obtain an image.

2. Inspection before Use
Prior to use, the probe must be carefully inspected that it is
appropriate for use.
2.1 Inspection of appropriate connection
2.1.1 Confirm that the system is correctly operating.
Refer to the instruction manual for the ultrasound
diagnostic scanner.
2.1.2 Do not attach or connect unauthorized devices nor
instruments on the probe, such as unauthorized biopsy
attachments.
2.2 Inspection of material surface
2.2.1 Visually inspect that the surface of the probe and head,
housing, the cable and the connector for any crack, scratch
or denaturalization. If you find any damage, do not use
the probe and contact a service support immediately.
2.2.2 Visually inspect the magnetic sensor attachment and the
spacer for EZU-RV2S for any crack, deformation or
denaturalization. If you find any damage, do not use them
and contact a service support immediately.
2.2.3 Visually inspect the elasto coupler for any crack,
deformation or denaturalization. If you find any damage,
do not use the elasto coupler. If you find any damage, do
not use the elasto coupler and contact a service support
immediately.
