5.4.2 Maintenance of the tubes and the mouthpieces

PHYSIO-ASSIST tubes and mouthpieces are manufactured from biocompatible polymers, and are latex-free and phthalate-free.

5.4.2.1 Expiratory kits TUB03_EU and TUB10_EU

The mouthpiece packaging carries the single use symbol

This indicates that the mouthpiece must imperatively be replaced after each use

The tube must be replaced at the same time as the filter, after 3 or 10 uses

After each use, wash the tube:

Wash the tube in soapy water

Rinse thoroughly

Dry the tube in the vertical position to remove all traces of water

At the frequency recommended by the specialist, disinfect the tube:

The disinfection process most compatible with the materials used to manufacture expiratory kits is cold immersion.

Immerse the tube in a container filled with:

- Either 70% isopropyl alcohol, for 5 min

- Or 3% hydrogen peroxide for 30 min

Rinse with sterile water (it is possible to sterilise the water by boiling it)

Dry the tube thoroughly in the vertical position to remove all traces of moisture and all disinfectant product residues

Wait until it is completely dry before putting the tube in the plastic bag

Place the kit in the plastic bag checking that it belongs to the patient concerned

Due to the plastic materials used, disinfection in autoclave (121° or 134°C) is only possible for the mouthpiece. The tube is not autoclavable, and would be damaged if exposed to a temperature above 60°C.

To avoid damaging the filter during washing or disinfection, make sure to disassemble it from the tube and keep it for reinstallation after cleaning.
