During the process, the stages of the cycle will be displayed on the screen:
Note:
The control system incorporates a safety feature that prevents changing programs if the
door is closed
.
This protection is intended to prevent running an inappropriate program if the autoclave is
loaded, but the cycle is not immediately started
.
If the operator for example inserts the load into the chamber, closes the door and leaves the
room and another operator/user tries to change the program, the operator/user will not be able
to do this unless the door is opened and the type of load inside the chamber can be seen
.
The
autoclave offers four preprogrammed sterilization programs
Using the UP/DOWN keys enables the user to select the programs
5.2.
Cycle Process Description
Air-removal stage; vacuum pulses are performed
.
Heating stage: steam is inserted into the chamber until the sterilization
temperature is reached
.
Sterilization temperature is maintained constant during the sterilization
time.
Fast exhaust, steam is exhausted out of the chamber at a fast rate until
pressure decreases to ambient pressure.
For Wrapped 134 and Wrapped 121. Drying by heating of chamber and
air circulation to remove leftover moisture from the instruments and
wraps.
5.3.
Vacuum Tes Process Description
Vacuum is produced in the chamber, down to P1=7 kPa. At this stage
all the valves close. The autoclave remains in this stage for 5 minutes.
This period enables the condition in the chamber to reach equilibrium.
After the 5 minutes have elapsed the printer records the pressure that is
referred to as P2. At this point the test begins and lasts 10 minutes.
At the end of the test, the printer records the results. The pressure at
the end of the test is referred to as P3.
Notes:
During the test period the autoclave is not heated. During the test period the screen color
is purple. If the vacuum test failed, the screen color changes from purple to yellow. If the
vacuum test is completed, the screen color will remain purple. Even if the vacuum test is
completed, the operator shall check the test results and consider whether the test results
are acceptable or not
The stages names are as follows:
