Handpiece sterilization
Frequency
Hazard for the patient.
The handpieces must be sterilized before use and can withstand
up to 200 cycles.
The Operator must comply with the rules of the national
commission for hygiene, disinfection and sterilization.
The handpieces are made of plastic material resistant to heat and
knocks (PSU - Polysulfone).
Replace the hand-pieces as soon as these become cracked or
deformed, as these could fall in the patient area.
Hand-piece fitting / removal:
-
Press the hand-piece release button and remove it.
-
Insert the handpiece in the support, following the guide
provided until it is locked in position.
Clean and disinfect the handpieces in the traditional way before
sterilization. They can be cleaned with a mid-alkaline detergent free
of active chlorine. To disinfect the handpieces, we suggest using
alcohol or aldehyde-based products. The disinfectants must be
approved by the manufacturer for use on polylsulfone (PSU). After
disinfecting, rinse off the detergent residues with plenty of water.
The handpieces fit into a suitable sterilization pack (disposable
sterilization pack, e.g., plastic/paper bags; single or double pack),
before being sterilized.
The handpieces can withstand about 200 steam sterilization cycles
in accordance with the following parameters:
-
steam sterilization at 121°C and 1.3 bar for 25 to 30 minutes
-
steam sterilization at 134°C and 2.3 bar for 4 minutes
Do not exceed a sterilization temperature of 134°C.
Strictly keep to the ISO 17665-1 standard.
When placing in the autoclave, make sure the open side of the
handpieces is turned downwards. The handpieces must be free and
not burdened by other material being sterilized.
Damaged handpieces must no longer be used.
