To clean a
reusable
turbine, remove it from its housing in the MiniFlowmeter
by turning
it anti-clockwise and pulling gently. To facilitate removal, you can push the bottom of the
turbine gently with a finger.
Soak the turbine in a cold liquid detergent and shake it so as to remove any impurities that
have deposited inside; leave to soak for the period of time recommended by the detergent
manufacturer that is shown in the instructions for use.
WARNING
To avoid irreparable damage to the turbine, do not use alcohol or oil based
detergent solutions and do not soak in water or hot solutions.
Never place the turbine in an autoclave. Do not sterilise the turbine.
Never clean the turbine under running water or spray with other liquids. If no liquid
detergents are available, clean the turbine with at least clean water.
MIR recommends the use of Dupont Perasafe that has been tested on all MIR
sensors.
Rinse the turbine by immersing it in clean water (
not hot
).
Shake off any excess water off the turbine. Leave the sensor to dry by placing it in an upright
position on a dry surface.
Before re-fitting the turbine, check that it is working properly. It is good practice to visually
check that the blades are moving freely. Place the turbine on its side and slowly move the
blades left and right. They should rotate freely. If this is not the case, the accuracy of
readings is no longer guaranteed and the turbine will have to be replaced.
On completion of cleaning, replace the turbine in its housing making sure that it is in the
right position as shown by the closed padlock symbol on the MiniFlowmeter.
To insert the turbine correctly, push it fully in and turn it clockwise until it clicks into place
inside the plastic housing.
To double check that the turbine is working correctly, repeat the checks described in 4.1.1;
if the turbine is still problematic, replace it with another.
WARNING
If disposable turbines are being used, do not perform any cleaning operations, but
replace the turbine for a new patient.
4.1.1
Checking correct turbine function
•
Turn the
spirolab
on and act as if you wanted to perform a spirometry test
•
Take the MiniFlowmeter in one hand and move it slowly from right to left and vice
versa so that air passes through the turbine,
•
If the blades move correctly, the device will emit repeated beeps that vary in frequency
with the flow of the air passing through
