Riester 480214GR Stethoscopes
Important Information Before Use:
You have purchased a high-quality Riester stethoscope, which has been manufactured according to the guidelines 93/42 EEC and is subject to continuous quality control checks.
Significance of the symbol on the folding box:
ATTENTION, please see the instruction manual!
The stethoscopes are latex-free.
Please read through the Instructions for Use carefully before using and keep
them in a safe place. Please note that the perfect functioning of the
stethoscope can only be ensured if original accessories from Riester are used.
Designated Use:
Stethoscopes are sound-conducting instruments to be used for auscultation of
body and organ sounds, especially of heart and lung; meaning they are used in
order to diagnose illness of internal organs. In medical science, doctors or
other trained medical professionals use a stethoscope in order to assess
sounds and noises linked with the function of heart, lung and bowel. During
blood pressure measurement, a stethoscope is used to capture Korotkow blood
flow murmur (Korotkow sounds) leading to a determination of systolic and
diastolic blood pressure. The Riester stethoscope range offers all prospects
for perfect auscultation from adults to children up to neonates.
Low/High Frequencies:
duplex®, duplex® baby, duplex® neonatal, tristar®, ri-rap®: By turning the
chest-piece, the membrane (high frequencies) or the bell side (low
frequencies) can be set. When performing auscultation, it is essential to
ensure that the surface adaptation is good. When measuring blood pressure, it
is possible to push the chest-piece partly under the cuff with the membrane
side showing downwards. It is possible to recognise immediately on the
closed/opened bell outlet which side is active. After putting on of the
binaural and slightly stroking across the membrane, it is possible to tell
acoustically whether the membrane is active. With ri-rap® model it is also
possible to change the small membrane side alternatively to an open bell. The
different bell sizes are to be found in the box with the accompanying
replacement parts.
cardiophon 2.0, duplex® 2.0, duplex® 2.0 baby, duplex® 2.0 neonatal:
Our new models do have a special marking on the topside of the tubing
connection showing the user which membrane is currently open.
Adjustment/Putting on of Binaurals
duplex®, duplex® baby, duplex® neonatal, tristar®, anestophon®, ri-rap®:
Please ensure that the binaural are adjusted to the anatomically correct
angle, i.e. the binaural are to be worn such that they slightly sit in front
(see Fig.A).
The angle can be adjusted by turning the binaural individually. The ear-tips sit correctly if they rest completely at the same angle as the external auditory canal and disturbing external noises are optimally blocked out. The soft Riester ear-tips are particularly well-suited for this reason. In case the contact pressure of the binaural is too strong or too weak, proceed as follows: In case contact pressure is too weak, take both binaural and press them together, as shown in Fig. B. In case contact pressure is too strong, take both binaural and expand them, as shown in Fig. C.
cardiophon 2.0, duplex® 2.0, duplex® 2.0 baby, duplex® 2.0 neonatal:
Binaural are anatomically correctly pre-adjusted during production, contact
pressure however of binaural may be adjusted individually, (Fig. B and C), ear
olives are pivotable and do have an extra-soft material. These characteristics
lead to perfect sealing of the auditory canals from external noises and
furthermore to no disturbing noise due to movement of ear olives inside the
auditory canal even during the movement of the stethoscope.
ATTENTION! Ear olives are not meant to enter too deeply into the auditory canal.
Exchanging the membranes:
duplex®, duplex® baby, duplex® neonatal, tristar®, anestophon®, ri-rap®:
In order to change the membranes, take the non-chill ring between the thumb
and index finger and pull it off the chest piece. Place the non-chill ring
with the flat side facing downwards on an even surface and place the membrane
into the non-chill ring with the printed side facing upwards. Take the non-
chill ring with the membrane and push it onto the chest piece. For the chest
piece of ri-rap®, please unscrew the ring nut, put the membrane in and fasten
the ring nut again. If membranes with a bulge are used, the bulge needs to
point away from ri-rap® chest piece.
cardiophon 2.0, duplex® 2.0, duplex® 2.0 baby, duplex® 2.0 neonatal:
In order to change the membranes, take the non-chill ring between the thumb
and index finger and pull it off the chest piece. Place the new membrane onto
the chest piece with the printed side facing upwards, put the non-chill ring
onto the chest piece in the correct position and push the non-chill ring onto
the chest piece with a semi-circular movement. Please make sure the membrane
remains correctly placed inside its bordering and doesn’t move.
Care instructions
General Note
Cleaning and disinfection of medical products are meant to protect patients,
users, and third persons and lead to value retention of medical products. Due
to product design and materials used, there is no possibility to define the

eliminate the eventual remains of the disinfectants.
ATTENTION!
- Clean ear olives regularly and check on its free passageway.
- Do never put stethoscopes into liquids!
- Stethoscopes are not meant to undergo machine-processed maintenance and sterilization. It may lead to irretrievable damages!
- Never use disinfectants based on phenol to clean and disinfect the stethoscopes.
- The pH-value of used solvents has to be between 4.5 and 10.
- Never use stethoscopes without ear olives/membranes!
