Equipment Description
Probes
Each probe consists of two crystals; one transmits ultrasound waves and one receives the re fl ected
waves. The initial energy beam is as wide as the crystal. The probe’s two connectors can be plugged into
either of the two jacks on the Doppler that match the probe frequency. The Doppler is tuned to the probe
frequency. The frequency is identi
fi ed on the panel next to the jacks and on the label attached to each
probe cable.
Damage to either crystal will impair or prevent probe function. The material covering the crystals can be
damaged by abrasion, soaking in alcohol or cleansers, and excessive heat.
The 915-BL comes with a 2.1-2.25 MHz (frequency speci fi ed) precordial probe and either a 8.0-9.9
MHz (frequency speci fi ed) standard pencil probe or fl at probe. The precordial probe is used to detect air
emboli in the heart. The pencil probe is used to detect blood fl ow and monitor systolic blood pressure in
the legs. The fl at probe is designed to be taped on the wrist for repeated blood pressure measurements.
Infant
Adult
Skinny Pencil Probe
(optional at additional cost)
Frequency: 8.0-9.9 MHz (Speci fi ed)
Diameter: 1/4 in
Cable length*: 5 ft standard
The smaller probe crystal concentrates power to produce a beam with higher
intensity than the standard probe, providing better resolution for small vessels.
Flat Probes
(an option with kit)
Frequency: 8.0-9.9 MHz (Speci fi ed)
Size: Adult 5/8 in X 3/4 in; Infant 1/2 in X 5/8 in
Cable length*: 5 ft standard
Crystals are set into the plastic so that the ultrasound beam goes into the vessel at about 15 degrees
from perpendicular. Flat probes are easily taped into place for taking repeated measurements.
*7 and 10 ft cable lengths are available by special order. Doppler must be tuned to probes with longer cables.
Standard Pencil Probe
(an option with kit)
Frequency: high: 8.0-9.9 MHz (Speci fi ed)
Diameter: high: 3/8 in
Cable length*: 5 ft standard
Standard diagnostic probe.
Precordial Probe
(included with kit)
Frequency: 2.1-2.25 MHz (Speci fi ed)
Diameter: 3/4 in
Cable length*: 5 ft standard
(Double Shielded)
May be used for detecting air emboli in
the heart.
Probes with double-shielded
cables can be ordered for use
in locations with high levels of
electrical interference.
