16. Preparation
During disinfection and cleaning, it
is absolutely vital that the valid acci-
dent prevention procedures for the
surgery are observed (e.g. gloves,
protective glasses, mouth
protection)
The measures described concerning
disinfection and cleaning or sterilisation
in no way replace the surgery rules and
regulations�
Before treating every patient, check that the fol-
lowing parts have been sterilised:
- suction hose including the hose adapter, suc-
tion handpiece and suction cannula
- collector with its cover, splash guard and
handle�
Risk assessment and classification
The VC 45 is a medical product that comes into
contact with blood and internal tissues�
In the Federal Republic of Germany, for exam-
ple, a risk evaluation must be carried out and
medical products used in dentistry are to be
categorised prior to preparation according to
the "Recommendations of the Commission on
Hospital Hygiene and the Prevention of
Infections"�
- Collector with its cover, splash guard and han-
dle, suction hose with hose adapter, suction
handpiece and suction cannula:
"Semicritical B"
with the increased requirements to the
preparation in each case
The instructions described below have
been validated by Dürr Dental as suita-
ble and are recommended for the prep-
aration of VC 45 components before
and after use�
The surgery manager is responsible for
ensuring that the correct and safe prep-
aration of the instruments is carried out
using suitable appliances, materials and
trained personnel in order to produce
the desired results� Validation and rou-
tine monitoring of the preparation pro-
cedures are necessary� Any and every
deviation from the procedures de-
scribed below by preparation staff is
solely the responsibility of the personnel
in terms of effectivity and the possible
negative repercussions�
Preparation process
The preparation process (disinfection, cleaning,
sterilisation and storage) of the VC 45 compo-
nents after every use is in accordance with the
preparation information according to
EN ISO 17664�
16.1 Pre-cleaning and disinfection

tion hose should be disinfected� Draw up ap-
prox� 0�5l disinfectant (e�g� Orotol Plus or an-

tal) and allow sufficient time to work�
Observe the max. level permitted in
the collector.
• Remove the suction hose with the hose
adapter piece out of the collector lid using a
