Automated Wash Procedure
Handpiece, Probe Cover and Wrenches
Point of Use
Immediately following procedure perform the following:
•
Flush handpiece lumen with minimum 100 mL of saline to clear the bore of debris.
•
Wipe all reusable devices to remove visible blood and debris.
CAUTION: DO NOT use saline to wet the tray and tray contents before transport to the decontamination
processing area.
NOTE: If transport to the decontamination processing area is delayed, cover the tray with a damp cloth
or spray the tray and its contents with a pre-cleaning foam. The pre-cleaning foam will minimize the
drying of soil and facilitate later decontamination processing.
Pre-Cleaning
•
The following should be performed on a disassembled handpiece:
•
Remove the probe and all housing components.
•
Prepare neodisher® MediClean forte at 3.9 mL per liter of water (5/8 oz. per gallon water). Water
should be lukewarm (<40°C, <104°F).
•
Use a tight-fitting brush dipped in the prepared cleaning solution to clean the lumen of the hand-
piece by inserting the brush fully through the lumen until visible from the other side a minimum of
four times, rotating the brush as it is inserted.
•
Rinse all residual soap from the handpiece under warm running water for a minimum of one minute.
•
Visually inspect internal and external surfaces of the handpiece including the pin cavity and repeat
the above steps as required until all visible debris and staining are removed.
Automated Wash
and Disinfection
When placing the handpiece into the automated washer, place on the top shelf of the washer. Attempt
to align the lumen in the general direction of the water jet flow in the washer but at a slight angle to
facilitate draining during the drying cycle.
Process the handpiece and all reusable components and accessories using the following cycle parameters:
*Durations listed are minimum acceptable. Longer durations than those specified for cleaning and
disinfection are acceptable.
Post-Cleaning
Inspect all items for cleanliness and damage following cleaning and prior to terminal sterilization.
