9.5.2.2 Pretreatment
Pretreatment must be carried out both during automated and manual cleaning
and disinfection. Please note that the disinfectant used for the pretreatment serves
only personal protection against contamination and cannot replace the sub-
sequent disinfection carried out after the cleaning step.
Directly after the application (no later than within 2 hrs), large impurities must be
removed from the reusable tube set.
Instruction
1. If necessary, remove the protective caps of the spikes (7) (see Fig. Pressure
chamber membrane and its position in the inflow tube set [
}
41]).
2. Open the tube clamps
(8)
.
3. Rinse the tube set and the membrane for at least 1 min under running water
(temperature < 35 °C/95 °F). Rinse all lumina of the tube set three times using
a disposable syringe filled with water (minimum volume 100 ml).
4. Place the tube set and membrane in a freshly prepared cleaning solution. Ob-
serve relevant requirements as listed in Chapter General Notes [
}
39] concern-
ing the selection, concentration, temperature, and exposure time.
5. Rinse all lumina of the tube set three times using a disposable syringe filled
with cleaning solution (minimum volume 100 ml).
6. Manually remove all externally visible particles with a clean soft cloth and soft
brush that is used only for this purpose and that does not scratch the surface.
7. Rinse the tube set and the membrane for at least 1 min under running water
(temperature < 35 °C/95 °F). Rinse all lumina of the tube set three times using
a disposable syringe filled with water (minimum volume 100 ml).
If you use a combined cleaning and disinfecting agent for this purpose - e.g., for
reasons of occupational safety - please take into account the following:
• They should be aldehyde-free (otherwise fixation of blood contamination)
• They must have a tested efficacy (e.g., VAH/DGHM or FDA/EPA approval/ clear-
ance/registration, or a CE marking)
• They must be suitable for disinfecting the product
• They must not contain any of the components listed under General Notes
[
}
39] and are compatible with the product.
