Cleaning The Accessories; Cleaning The Transducer - Micro Direct MicroLab Operating Manual

Cleaning the Accessories

With the use of a SpiroSafe filter (#3385) or a MicroCheck one-way valve
safety mouthpieces (#3395) for each patient, cleaning of the transducer is
recommended once a month.
When using the disposable cardboard mouthpiece (adult: #3314SB or
#3314B5, pediatric: #3301) without a filter and under the prerequisite that
the patient was instructed only to exhale into the transducer, the following
parts have to be cleaned once a day: transducer and pediatric adapter (if
one was used).
With any other use as described above, all contaminated parts must be
disinfected between patients.
IMPORTANT NOTE: Used single patient nose clips, mouthpieces and
SpiroSafe filters must be disposed of immediately after use.
If there are changes on the material surfaces (cracks, brittleness) the
respective parts must be disposed of.

Cleaning the Transducer

The transducer requires no routine maintenance or servicing. However, if
you wish to disinfect or clean the transducer, it may be removed by
means of the following procedure:
1. Rotating the turbine transducer anti-clockwise until the locating pip
lines up with the small rectangular cut-out in the housing as shown below.
2. Gently pull the transducer away from the housing.
3. The transducer may now be immersed in warm soapy water for
routine cleaning or immersed in cold disinfecting solutions for a maximum
of 10 minutes (Alcohol and chlorine solutions MUST be avoided).
4. After cleaning/disinfecting, the transducer should be immersed
briefly in distilled water and left to dry.
5. Re-assemble the mouthpiece holder.
