4.2 CLEANING THE REUSABLE TURBINE
The turbine utilized with SpirolabIII is of one of two categories: disposable or reusable. These guarantee precise
measurements and have the advantage of requiring no periodic calibration. In order to maintain these characteristics, a
simple cleaning is required prior to each use (only for the reusable turbine). This operation also ensures perfect
hygiene and thus the highest possible safety conditions for patients.
Cleaning of the disposable turbine is not required as it is supplied already clean in a sealed plastic bag. It must be
disposed of after use.
The maintenance operations to perform are cleaning and controlling of the turbine.

Miniflowmeter Turbine Mouthpiece
To clean the reusable turbine, remove it from its compartment in the MiniFlowmeter by turning it anti-clockwise and
pressing lightly. It can be helpful to push it gently from underneath with one finger.
Immerse the turbine in a cold sterilising liquid and move it within the liquid to remove any impurities which may be
deposited inside. Leave it to soak for at least the time recommended by the producer of the cleaning solution, as shown
in the instructions (in general at least 20 minutes).

Rinse the turbine by immerging it in clean water (not hot).
Shake off the excess water from the turbine and leave it to dry, standing it vertically on a dry surface.
To ensure that the turbine is functioning correctly before replacing it inside the instrument it is good practice to make a
visual check of the rotation blade. Placing the turbine tube horizontally and moving it gently from left to right and vice
versa, the rotation blade (rotor) must rotate freely. Otherwise, accurate measurement is no longer guaranteed, so the
turbine must be replaced.
Once the turbine has been cleaned, insert the turbine tube in its place following the instructions indicated by the “lock “
symbol printed on the MiniFlowmeter.
To insert the turbine correctly, push it and then turn it clockwise until reaching the stop, which ensures that the tube has
been blocked inside the casing.
Verify the free movement of the turbine:
• Switch on SpirolabIII as if to make a spirometry test (for example FVC).
• Hold the MiniFlowmeter in one hand and move it gently from side to side, so that air passes through the turbine.
• If the rotor within the turbine is turning correctly, then you will hear a beep that indicates that the turbine is moving
within the specific low flow range.
• If moving the turbine from side to side at a constant velocity, regular beeps or no beeps at all are heard, then
proceed with the cleaning of the turbine.
