2.6 Process validation
The aim of process validation is to achieve a high level of safety in the recondi-
tioning of medical devices in order to afford the operators and patients the great-
est possible protection.
Process validation consists of:
a) Type testing / factory testing
b) Process validation consisting of:
• IQ - Installation Qualification
• OQ - Operational Qualification
• PQ - Performance Qualification
c) Routine testing / Annual requalification
(refer to appendix EN ISO 15883-1 November 2001, Chap. 6, Pages 35-37)
NOTE
Further information on process validation may be obtained from Belimed
Customer Service.
CAUTION!
Validation must only be carried out by authorised persons!
Devices must only be operated with processes validated in accordance with
regulations! Only use components (items to be washed, racks, programmes,
chemicals) which have been validated together.
The safety of operators and patients may be compromised if the devices
used are not validated in accordance with regulations.

Pre-treating medical devices
4 Pre-treating medical devices
4.1 Responsibility for pre-treatment
The owner is responsible for pre-treatment of medical devices. The best possible
washing results are only to be achieved with correct pre-treatment as intended.
Various treatments fix proteins and may contribute to preserving prion infectivity.
4.1.1 SOPs (Standard Operating Procedures)
The contents of the following criteria and specifications must be regulated:
• Product responsibility
• Transport routes and duration of waste disposal (time for soiling to dry in)
• Type of soiling (blood, ointments, bone meal...)
• Material properties and compatibility of the items to be washed (risk groups
acc. to RKI Ordinance)
• Consideration of all operating instructions and reconditioning regulations for
medical devices
• Necessary knowledge of the medical devices to be reconditioned
• Maintenance plan and regular inspections
Belimed recommends producing work instructions which describe the procedure
within a working process.
4.2 Preparing medical devices
All inner and outer surfaces must be accessible for cleaning (open valves, taps,
joint instruments...) Special caution is required for the lumen. Disassemble MIC
or other complex instruments according to the manufacturer's specifications.
CAUTION!
Always observe the specifications from the medical device manufacturer!
CAUTION!
The air bubbles in the foam prevent pressure building-up in the cleaning sys-
tem and therefore the best possible contact between the cleaning agent and
the items to be washed.
CAUTION!
Not all medical devices are suitable for mechanical reconditioning (see Chap.
2.5 "Fields of application for the device")

Pre-treating medical devices
Instruction Manual WD290 001
11/39
© Belimed 10268
4.3 Pre-cleaning pre-treatment
Remove coarse soiling immediately after use. Dried-on blood or tissue reduces
the effectiveness of cleaning.
4.3.1 Avoiding subsequent cleaning
Various treatments fix proteins and may contribute to preserving prion infectivity.
The following pre-treatment methods may cause impairments in subsequent
washing:
• Pre-treatment with aldehydic disinfectants
• Pre-treatment with alcohol solutions
• Pouring antiseptic solutions on the items to be rinsed
• Aldehyde and alcohol vapours
• Heat pre-treatment
Small quantities of foam are permissible with manual cleaning in the immersion
bath or ultrasonic cleaning.

6 Self-disinfection
6.1 Why self-disinfection?
Microorganisms form in the washing chamber, tubing and DI boiler after a pro-
longed period of disuse. Following thermal disinfection step, residues of dead
bacteria on the medical device may constitute a risk for patients.
In the case ofactive self-disinfection the owner is requested to perform self-dis-
infection after a programmed period (24 hours as standard) following the last pro-
gram run.
6.2 Starting self-disinfection

NOTE
If there is no mains supply (mains switch OFF) the timer is not active, as the
request for"Self Disinfection Start" always appears when active self-disinfec-
tion is switched on.
CAUTION!
Do not wash any items with the self-disinfection program! There is no cold
pre-rinse. There is the risk of excessive foam formation and fixing proteins.
WARNING!
Do not touch the door or its surrounding paneling during the closing process.
A crushing hazard exists.
If any objects are trapped between the panel and door, the technical person-
nel must be informed to rectify the problem.
