Safety rules/contraindications

• To avoid injury, do not use a stethoscope without ear tips! If
the rubber is damaged or has come off, the ear tips must be
replaced before the next use.
• The rotatable ear tips have the rubber cover attached. Always
make sure that it is correctly positioned before use.
• Do not touch water with stethoscope.
• Loud sound can interfere with the perception of noise.
• Do not sterilize in autoclaves.
• Keep the stethoscope away from heat, solvents, and oils.
• Before each use, please check whether the stethoscope is
operating properly. Do not use the device in case any damage
is detected.
• Only original spare parts and accessories from KaWe may be
used.

4. Application

The basic principle of auscultating with a stethoscope is the
"fluctuating air column". For sound transmission, a closed air
column must be formed.
• When putting on a stethoscope with a headset, the bows are
applied so that the ear tips are directed slightly forward,
towards the examiner's nose, so that the anatomical
structure of the ear contributes to their close contact with the
acoustic meatus.
• Apply the membrane or funnel to the examined place. The
following models have a double function of membrane/
funnel:
- Planet & Planet Air
- Prestige & Prestige light
- Double
- Rapport
- Profi Cardiology
- KaWe COLORSCOP Duo
- Duo Stethoscope for nurse training
• Funnel or membrane can be selected with a double
movement of the stethoscope head. If the membrane is
open, the funnel closes and vice versa.

• Membrane-head stethoscopes are used either for
auscultation of anatomically curved places and/or in cases
where the low frequency ranges of the auscultation signal
are of little or no importance for the diagnosis.
• The funnel on the chest is used for low frequency
diagnostics. In particular, this is required for cardiac
auscultation. The edges of the funnel must adhere tightly to
the entire examined part of the body.

5. Preparing for operation

• Check the stethoscope for damage and contamination
(especially diaphragm, hoses and headset incl. ear-tips).
The system must be closed.
• Check that the ear-tips are properly seated.
• Individually adjust the headset.
After successful completion of the inspection and after appro-
priate hygienic preparation, the stethoscope can be used to ex-
amine patients.

6. Hygienic preparation

Clean and disinfect the stethoscope periodically to prevent cross
contamination.

Cleaning and disinfection

After examining each patient, the stethoscope is to be cleaned
and disinfected with a 70% alcohol solution (for example, a
soaked tissue). The duration of exposure of the agent used must
be taken into account.
Besides, perform a thorough cleaning of the individual compo-
nents of the stethoscope periodically. Use a 70% alcohol soluti-
on or a mild soap solution. For thorough cleaning the ear tips
and membrane may be removed. Remove the corresponding
retaining ring on the diaphragm. Handle the diaphragm with
care to prevent damage.
Reassemble the stethoscope components only after they are
completely dry.
Automatic cleaning is not allowed.

Sterilization

Stethoscopes are not suitable for sterilization processes.
