Masks cleaning and disinfection
The face masks should be cleaned and sterilised after each test.
Disassembling the different parts of the mask
1. Remove the valves from their place.
2. Remove the adapter for the optoelectronic reader.
Cleaning the mask
1. Clean the mask with hot water and a soap solution to remove the impurities.
2. Rinse the mask with energy in running hot water.
Disinfecting the mask
It’s possible disinfecting the mask following these procedures:
•
Standard autoclaving method
Rapid cycles of autoclave lasting 10 minutes at 132°C (270°F)
Heavy cycles of autoclave lasting 30 minutes at 121°C (250°F)
Pre vacuum cycles of autoclave lasting 30 minutes at 121°C (250°F)
•
Hetilene oxide method (ETO)
The hetilene oxide doesn’t deteriorate the face masks. Sterilisation by this method
is not advised unless sufficient data is available regarding the time required for
complete out-gassing of residual ETO. If you use this method, follow carefully the
instruction provided by the maker of the sterilising product.
•
Pasteurisation
The disinfecting with hot water is a sterilising method that may be used with the
silicone masks.
Permapure maintenance
•
Do not bend, squash or deform it.
•
Do not keep it in open air, if not used, especially in crowded or smoky places.
• If saliva is entered in the tube, replace it immediately, because it lost its functions.
•
Periodically grease the o-ring on the connector in order to simplify the flowmeter
connection.
•
Replace it every 100 test / 6 month.
Inspections
The equipment requires easy inspections to be carried out in order to assure a proper
electrical and mechanical safety level in the years.
These inspections are highly recommended after a rough use of the equipment or after a
period of storage in unfavourable environmental conditions.
Referring to the electrical safety, it is important to check the conditions of insulation
materials of cables, plugs and any other visible part by means of simple inspection,
when the equipment is switched off and adapters (or electrical feeders) are disconnected
from the supply mains.
Mechanical parts to check are: the turbine and breathing circuits.
Follow these instructions:
•
extract the turbine from the optoelectronic reader;
•
verify, by inspection, that the turbine axis fits correctly its seats and the blade is
strongly fastened on the axis itself (it can be useful to shake slightly the turbine in
order to note any anomalous movement).
Check if there are any torn or broken components in the breathing circuits: remember
that they can create safety risk to patients during tests.
Replace the fuses
The fuses can be replaced easily in the following way:
Warning: Do not use
synthetic or petroleum-
based products for the
masks cleaning.
