Note
The spirodoc turbine measurement system is calibrated in the factory and does not require any adjustments or
calibrations.
Warning
If you are going to perform the spirometry test with a “single-
patient” disposable turbine it is important to use a new turbine for
every new patient. The characteristics, accuracy and the hygiene of
the disposable turbine can only be guaranteed if it has been
conserved beforehand in its original sealed packaging.
The disposable turbine is made of plastic and its disposal after use
should adhere to the local authority guidelines / norms.
The correct functioning of the re-usable turbine can only be
guaranteed if it has been cleaned in the correct manner and is free
from foreign bodies which could alter its movement. If the turbine
has not been cleaned sufficiently this could cause cross
contamination from one patient to another. Periodic cleaning
should only be done when the instrument is for personal use and
will only be used by one patient. The cleaning of the turbine
should be done following the guidelines in the User’s Manual.
The following information applies to both turbine models.
Do not expose the turbine to a direct jet of water or air, and avoid contact with high temperature liquids.
Do not allow dust or foreign bodies to enter the turbine sensor, in order to avoid incorrect functioning and possible
damage. The presence of any impurities (such as hair, sputum, threads etc.) within the body of the turbine sensor may
seriously compromise the accuracy of the measurements.
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 SPIRODOC and setup the device to perform a spirometry test (for example FVC).
Hold the SPIRODOC 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 spirodoc 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.
