Preparing for the Next Patient
Once scanning is complete, it is time to get ready for the next patient.
Cross-Contamination
There is no reason to routinely sterilize imaging plates unless you believe they
have been contaminated. If an imaging plate has touched a contaminated surface,
wipe it gently with lint-free gauze dampened with a cold sterilant as recommended
by the manufacturer. DO NOT SOAK. Two percent (2%) Gluteraldehyde solutions
will not damage the imaging plate if used as described. IMAGING PLATES CANNOT
BE AUTOCLAVED.
If a carousel has touched a contaminated surface, the intraoral imaging plate
holders
should b
e removed (see Chapter 5-1) and wiped with a cold sterilant
solution. The remainder of the carousel can be sprayed with an aerosol
disinfectant or soaked in a cold sterilant solution.
If the outside of the DenOptix QST scanner has been touched by a contaminated
s
ur
face, it must be cleaned. BEFORE PROCEEDING, TURN THE SCANNER OFF AND
DISCONNECT FROM THE POWER OUTLET. The outside of the scanner can now be
wiped with a towel dampened with cold sterilizing solution and then allowed to air
dry. DO NOT SPRAY OR SOAK THE SCANNER. If necessary, wipe the inside of the
carousel well with a cloth very lightly dampened with cold sterilizing solution.
NEVER SPRAY THE INSIDE OF THE CAROUSEL WELL. Be careful not to allow solvent
into the DenOptix QST scanner, which could damage the electronics inside. Allow
to air dry before connecting the power cord or turning the unit on.
It is the operator’s ultimate responsibility t
o
ensure that correct infection control
procedures, consistent with those recommended by the Board of Dental
Examiners, are followed and that effective cold sterilant and disinfecting sprays
are used.
Follow the steps on pages 4-3 and 4-4 to
era
se the imaging plate and protect it
from crosscontamination. You are now ready to take an X-ray on the next patient.
Power System ON and OFF
The DenOptix QST System is designed to be left on continuously. The laser is only operational
while the unit is actually scanning. If you wish to turn the system off, please remove the carousel
and use the following procedure.
1. Wait until any scan in progress is complete and the green light is on.
2. Save any changes you have made and close down the imaging software (for
example VixWin Pro software). To protect your data, frequently back-up your
files.
3. Turn the power switch in the back of the scanner to the “Off” position.
4. Turn off all computer components following any instructions from the
manufacturer.
5. If you live in an area of frequent thunderstorms or variable line voltages, you
may want to turn the unit off on a more regular basis. An uninterruptible
power supply (UPS) is recommended for areas with power quality issues.
