Flat Probe
Frequency: 8.0-9.9 MHz
Size: 1/2 in X 5/8 in
Cable length*: 5 ft standard
Description:
Easily taped into place for repeated
measurements. Crystals are set into the plastic so
that the ultrasound beam goes into the vessel at
about 15 degrees from perpendicular
Probe Design and Frequency:
Each probe consists of two crystals; one transmits
ultrasound waves and one receives the refl ected
waves. The initial energy beam is as wide as the
The probe frequency is specifi c to each instrument.
The probe’s two connectors can be plugged into
either of the two jacks on the Doppler unit that match
the probe frequency. The frequency is identifi ed
on the panel next to the jacks and on the label
attached to the probe cable (probes manufactured
before September 2006 will only be inscribed).
Disconnect the probes from the Doppler unit only for
Remove the red protective covering from the probe
tip before use.
Warning!
Damage to either crystal will impair or prevent probe
function. The material covering the crystals can be
damaged by ECG cream or paste, abrasion, soaking
in alcohol or disinfectants, and excessive heat.
Inspect the Probe:
Before each use, inspect the probe for any cracks
or breaks in the protective epoxy covering. Damage
that could allow for ingress of conductive fl uids,
such as acoustical coupling gel, can create a shock
or burn hazard if the Doppler unit’s metal case is
grounded and comes in contact with or is used with
other electronic equipment.
Use Coupling Gel:
The probe requires a conductive medium to maintain
an interface between the skin and the probe for
signal transmission. Use only a coupling gel made
for ultrasonic applications.
Care and Cleaning of the Probes
1. Remove the gel with a soft tissue after each probe use.
2. Wash any dried gel off the probe with running water.
DO NOT scrape off dried gel to avoid damaging the coating over the crystals.
3. User may opt to wipe probe tip with alcohol, surface germicidal cloth, or liquid
disinfectant (do not soak). Rinse probe tip with warm water to remove any residue
after cleaning/germicidal agent dries. Do not use bleach.
Do Not Autoclave the Probes
Temperatures above 57.2 degrees Celsius (135 degrees Fahrenheit) destroy the
crystal activity and cause the covering over the individual cables and the outer sheath
to shrink and crack. With a raised temperature, a severe loss of sensitivity will occur.
Autoclaving will void the probe warranty
