Medivators DSD-201 - Endoscope Leak Testing

Cycle Operation
Startup Phase
During start-up phase, the software monitors certain sensors. If any of the monitored sen-
sors are not satisfied during start-up, an error message is displayed and the process 1s
halted. To cancel the start-up phase, press the STOP key. To resume, resolve the error
according to the error message displayed, press the STOP key, and then press the Start key.
Please refer to the maintenance and troubleshooting section for appropriate instructions to
resolve error messages.
If the leak tester option is installed and enabled, a 40 second sheath test is activated during
the start-up phase. During that test the scope is pressurized to 160mmbhg for 20 seconds
then the pressure is monitored for the remaining 20 seconds. If the pressure drops below
50mmhg, a “Sheath Fail” error message is displayed and the process is halted. To cancel
the start-up phase, press the STOP key. To resume, resolve the issue according to the error
message displayed, press the STOP key, and then press the Start key.
Wash Phase
120
The wash phase consists of either a Soak segment or a Flush segment. The operator has
the choice to run either one of the segments or neither, but never both during the same
cycle programme. Setting the Soak time above zero using Setup 5, disables the second
segment. To run the Flush segment during a programmed cycle the operator must set the
Soak time to zero and the Flush to the desired time.
During Soak, the detergent is injected into the basin according to the programmed deter-
gent injection time. The default detergent injection time is 3 seconds (~9ml). Please refer
to the table in the Programming the Reprocessor section for the appropriate dilution and
timing settings. After injection, water fills the basin. If the re-circulation option is included
and enabled, the basin fluid is then flushed through the scope channels. Otherwise the
scope is soaked in the basin for the programmed soak time. The basin is then drained
while the scope channels are flushed with fresh water. A Rinse Soak period then follows
which is identical to the soak period. However, no detergent is injected during this time.
During flush, the scope channels are injected with detergent for the programmed injection
time and then flushed with water for the desired flush time. During this segment all of the
fluid exiting the scope is flushed down the drain.
