The turbines ensure high precision in measurements and have the great advantage of requiring no periodic calibration. In
order to maintain the characteristics of the turbine a simple cleaning is required prior to each use (only for the reusable
turbine). This operation will also guarantee perfect hygiene and the highest possible safety conditions for the patients.
Cleaning of the disposable turbine is not required, as it is supplied clean in a sealed plastic bag. It must be disposed of after
use.
4.3.4.1. Cleaning the reusable turbine
Cleaning of the disposable turbine is not required, as it is supplied clean in a sealed plastic bag. It must be disposed of after
use.
Turbine operation check:
• Turn on SPIROLAB and setup the device to perform a spirometry test (for example FVC).
• Hold the SPIROLAB with one hand and move it slowly sideways, having the air pass through the turbine.
• If the rotor spins properly the device will emit a series of acoustic signals “beeps”. The beeping frequency is a function
of the air flow passing through the turbine.
• If no beeps are heard while moving the device, proceed to clean the turbine
CAUTION
Periodically check the inside of the turbine to ensure that there are no impurities, corpuscles, or any foreign
matter like hairs which could inadvertently block or even slow down the mobile equipment in the turbine and as
a consequence compromise spirometry measurement accuracy.
To clean the reusable turbine, first remove it by pulling it gently from the Spirolab turning it anti-clockwise and pressing
lightly. It can be helpful to push it gently from underneath with one finger from the bottom of the turbine to lift it out of
its housing.
Immerse the turbine in a cold liquid solution and move it within the liquid to remove any impurities which may be
deposited inside. Leave the turbine immersed for the time specified in the instruction of the solution.
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 and the
turbine must be replaced.
Once the turbine has been cleaned insert the turbine tube in its place following the instructions indicated by the closed
lock symbol printed on the plastic casing of the Spirolab.
To insert the turbine correctly push it and then turn it clockwise until it reaches the stop, which ensures that the tube has
been blocked inside the casing.
4.3.4.2. Calibration of the reusable turbine
See instructions in the Calibration section of the User Manual of the device.
The turbines used on Spirolab do not require periodic calibration as they are already calibrated.
4.3.5. Internal software upgrade procedure
In order to upgrade the software winspiroPRO must already be installed and the PC must have an internet connection for
downloading the upgrades and firmware of the Spirolab from www.spirometry.com.
Launch winspiroPRO on the PC and connect Spirolab
to the PC using the USB cable.
