DGH TECHNOLOGY SCANMATE FLEX, Operator'S Manual

Page: 50 / 64

50 DEVICE CORDS (FLEX - PCABLE)
All device cords (probe cords, power cords, USB cords, etc.) should be routinely inspected for
bends, cuts, abrasions and other forms of damage. Cord connectors should be inspected for
cracks, abrasions, deformation, damaged/bent pins, etc.
A - SCAN PROBE (DGH6006)
The A - Scan probe housing should be routinely inspected of cracks, splitting, dents, sharp edges,
projections, deformation and other forms of damage. Special attention should be paid to the
probe tip that contacts the patient
’ s eye, ensuring that the surface is smooth and without cracks,
dents or blemishes.
B - SCAN PROBE (DGH1912, DGH1920)
The B - Scan probe housing should be routinely inspected for cracks, splitting, dents, sharp edges,
projections, deformation and other forms of damage. B - Scan probes should also be inspected
for leaks of the internal transmission fluid. Special attention should be paid to the probe tip that
contacts the patient
’ s eye, ensuring that the surface is smooth and without cracks, dents or
blemishes.
UBM PROBE (DGH1500) AND TRANSDUCERS (DGH1500 - 35, DGH1500 - 50)
The UBM probe housing should be routinely inspected of cracks, splitting, dents, sharp edges,
projections, deformation and other forms of damage. Special attention should be paid to check
for damage/deformation that may allow water ingress. The black o
- ring seals between the
transducer and probe should be checked for damage that may allow water ingress. If the o - ring
is damaged, it can be replaced with the manufacturer provided substitutes.
IMMERSION SHELL (P - 102)
The A - Scan Immersion shell should be regularly checked for chips, cracks, abrasions,
deformation and other physical damage. If damage is found, the shell should be discarded and
replaced.
ROUTINE MAINTENANCE — VERIFYING A - SCAN CALIBRATION
WARNING: Verifying calibration should not be performed while the device is in use with the
patient. Verifying calibration should be performed prior to use of the device.
A - Scan calibration should be verified routinely. The software must be placed into a test mode to
check calibration on a standardized polystyrene block (provided with unit). The following
procedure describes entering test mode and verifying unit calibration.
1. Navigate to the Patient Data Screen by selecting the “ Patient Data ” tab. In the “ Last Name ”
drop - down box, select “ Test Block ”.
2. Navigate to the A - Scan Screen by selecting the “ A - Scan ” tab. The current eye should be
displayed as “ Test Block ” in the waveform display screen, and the lens type drop - down box
should be frozen, displaying “ Test Block ”.
3. Place the arm of the Flex unit in the down position. Apply a small drop of water to the top
of the reference test block.
4. Apply the probe tip to the center of the reference test block.
5. Measurement of the test block should begin almost instantaneously. If not, move the probe
tip slightly until a measurement is obtained.
