Vascular Use: Vascular System
Product Description
The MedaSonics Tria Vascular Doppler System consists of a speaker unit and
5 MHz Probe. The probe is connected to the speaker unit via a coiled cord.
Speaker Unit
The speaker unit is comprised of the electronics, battery compartment,
on/off power control, volume control, on/off and battery life LED indicators.
The 3.5 mm audio output jack on the top of the unit allows private listening
with an optional stethoscope or the connection of a recording device.
The green LED on the face of the unit is lit when the unit is turned on. When
the battery falls below optimum performance levels, the yellow LED becomes
lit prompting the user to change the battery.
Vascular Probe
The 3/8-inch diameter ultrasound transducer, located at the tip of the probe,
generates signals which are processed and can be heard through the speaker
or optional stethoscope. The transducer frequency is 5.1 MHz.
Probe Retention
The Doppler probe is held fast to the speaker unit with magnets which can
be seen in the pocket on the right side of the unit. Simply place the probe
gently in the pocket and the magnets will retain the probe for storage and
transport. While the retention force of the magnets is high, it cannot prevent
the dislodging of the probe under extreme conditions, such as high impact.
Probe Connection
To remove the probe from the system, gently pull the gray connector out from the
base of the probe. To connect a probe, line up the tab on the end of the connector
with the notch on the end of the wand and push gently until they snap together.

Note:
The probe on the dedicated vascular Tria System is permanently wired to
the speaker unit and can not be removed.
Battery
The Doppler requires one 9V alkaline battery which is located in a compartment
in the back of the speaker unit. Battery life will vary according to frequency and
duration of exam.
Note:
A low battery can significantly degrade Doppler performance. When the
battery falls below optimum performance levels, the yellow LED on the front of
the unit becomes lit and the speaker volume will automatically drop to an unusable
level. This prompts the user to change the battery, returning the Doppler to peak
performance.
Operation (Speaker Unit)
On/Off Button:
The On/Off button is located on the left-hand side of the speaker
unit. The green LED on the face of the unit is lit when the unit is turned on.
Volume:
The volume control is located on the left-hand side of the unit below
the on/off switch. Rotate the thumb wheel to achieve the volume that is best for
the application.
Outputs:
The 3.5 mm audio output jack on the top of the unit allows connection
of a stethoscope or recording device.The speaker will automatically mute when
the stethoscope is plugged in.
Instructions for Use
Spread a generous amount of ultrasound coupling agent (ultrasound gel) on
the body surface to be examined. A fluid coupling agent is essential for proper
operation. Lack of signal can be due to loss of fluid coupling. Commercial
preparations provide good coupling, however, a soap solution or even water
can be used. Do not immerse the probe or use alcohol as a coupling agent.
