Hitachi L44 Instruction Manual page 20

Manual disinfection:
A) L44 probe
1) Prepare the disinfectant solution in a tank with cold water (please
follow the instructions of the disinfectant manufacturer regarding
application, concentration, microbiological efficiency, service
life and contact time).
2) Confirm the concentration of the disinfectant before immersing the
probe. Although Cidex® OPA does not need to be diluted, it is
recommended to use test strips to verify the concentration. The test
strips can indicate whether or not the concentration is above the
Minimum Effective
expiration date of the test stripes. Temperature of disinfectant
solution should be minimum 20 °C. The minimum contact time is 5 minutes.
If a different disinfectant is used, follow the manufacturer's
instructions. Please also consider the material compatibility for
the medical device.
3) Immerse the immersible part of the probe into the disinfectant (see
Fig. 5). Set a clock to insure the recommended contact time which
is 5 minutes.
4) Rinse the immersible part of the probe with deionized water for 1
minute. (alternatively: immerse the immersible part of the probe in
a tray filled with deionized water (see Fig. 5) for 5 min.)
5) Visually check the outer surface of the probe for leavings of the
disinfectant. If necessary, repeat the rinsing.
B) Elasto coupler
1) Prepare the disinfectant solution as stated in the procedure for the
probe.
2) Immerse the elasto coupler into the disinfectant (see Fig. 5). Set
a clock to insure the recommended contact time which is 5 minutes.
3) Rinse the elasto coupler with deionized water for 1 minute.
(alternatively: immerse it in a tray filled with deionized water (see
Fig. 5) for 5 min.)
4) Visually check the outer surface of the elasto coupler for leavings
of the disinfectant. If necessary, repeat the rinsing.
