6.2 Sterilization Prior to Use
Warning: The reusable Contour 3D Ring Sizer Set,
Model 7690S, is supplied NONSTERILE and must be sterilized
prior to use. Prior to sterilization, the sizers must be thoroughly
cleaned.
The following cleaning/disinfection procedure and sterilization
procedures have been tested by Medtronic and found to be
effective. A hospital may choose the procedure tested by
Medtronic or another procedure, which should be qualified. In
either case, the effectiveness of the procedure should be
established. Medtronic utilized biological indicators to establish
the effectiveness of the procedure.
Cleaning and Disinfection
Warning: The sizers should be removed from the handle prior to
cleaning.
Note: Contaminated sizers should not be allowed to dry prior to
implementing any cleaning/disinfection procedures. Medtronic
has established that the following manual cleaning and
disinfection procedure is compatible with these sizers:
1. Prepare a 470-ppm active quaternary solution and detergent
containing alkyl dimethyl benzyl ammonium chloride as the
active ingredient (eg, Mikro-Quat
®1
), using purified water.
2. Completely immerse each sizer in the solution for a minimum
of 15 minutes.
3. Rinse each sizer in a minimum of 3 liters of purified water.
4. Continue to rinse each sizer until it is thoroughly cleaned.
5. Gentle wiping of the sizer during rinsing may be necessary to
remove all adherent, visible soil.
Sterilization/Resterilization
Prior to sterilization, package the sizers in a single-use, self-seal,
autoclavable, plastic/paper pouch or other container suitable for
resterilization. Medtronic has established that one of the following
methods is compatible with this sizer set:
1. Normal autoclave cycle: 121°C (250°F) for 30 minutes
2. Flash autoclave cycle: 132°C (270°F) for 5 minutes
Sterilization was performed in an AMSCO Medallion general
purpose, gravity, single-door steam sterilizer with a fully loaded
container. The sterilizer has the following specifications:
■
Size: 51 cm x 51 cm x 96.5 cm (20 in x 20 in x 38 in)
■
Temperature range: 66°C to 138°C (150°F to 280°F)
■
Chamber pressure rating: 248 kPa (36 psig)
Note: As mentioned, each instit ution should use some method to
determine the effectiveness of the sterilization procedure.
Sterilization packaging should be consistent with standard
hospital sterilization practices.
Reuse
Medtronic performed a minimum of 50 sterilization cycles on the
sizers without any signs of wear being noted. However, prior to
any subsequent reuse, the sizers should be examined for signs
of wear (eg, cracking or crazing) or damage and replaced if any
signs are observed.
