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 TUB10_EU

The mouthpiece packaging carries the “single use” symbol

This indicates that the mouthpiece must imperatively be thrown away after each use

The tube must be replaced at the same time as the filter, after 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.

After washing or disinfecting, and before storing the tube in the plastic bag, it is important to rinse it

thoroughly and dry it to remove any residual disinfectant.
