7 Sterilization
34
Batch indication
comprises the checking of the indicators used in the sterilization program e.g.
MELAcontrol Helix or MELAcontrol Pro. Approval of the indicator strip is possible only if it changes colour
entirely.
Batch approval
comprises the checking of the process parameters using the sterilization results on the
steam sterilizer and the sterilization log as well as checking of the individual packaging for damage and re-
sidual moisture. The sterilization log records the approval of the batch and any indicators. Depending on
the setting in the user administration, approval for the sterile material requires the user PIN of the person
who provides approval for the batch and the indicators.
Removing the sterile material
CAUTION
Danger of burns from hot metal surfaces
n
Allow the device to cool sufficiently before opening.
n
Do not touch any hot metal parts.
CAUTION
Unsterile instruments resulting from damaged or burst packaging. This endangers the
health of your patients and practice team.
n
Should the packaging be damaged or have burst after sterilization, wrap the load again and
re-sterilize it.
If you remove the sterile material from the device directly after the end of the program, it is possible that
the instruments can be partially damp. According to the red brochure of the Arbeitskreis für Instrumente-
naufbereitung (AKI), the tolerable residual moisture is – in practice – a few drops of water capable of evap-
orating within 15 min, but actual pools of water are not acceptable.
Comply with the following specifications when removing the sterile material:
u
Never use force to open the door. This could damage the device or result in the emission of hot
steam.
u
Hold the mount level when removing it from the device. Otherwise, the load could slide off.
u
When removing the load from the device separately, ensure that the mount does not slide out
unintended.
u
Use a tray lifter to remove the tray.
u
Never touch the sterile material, the sterilization chamber, the mount or the inside of the door with
bare hands. The components are hot.
u
Check the packaging of the sterilized equipment for damage when removing it from the device. Should
the packaging be damaged, re-pack the load and re-sterilize it.
