Purpose

Stethoscopes are sound-conducting devices used to listen to body sounds, particularly from the heart and lungs, and for diagnosing diseases of internal organs. They are used by clinicians to assess tones and sounds related to the activity of the heart, lungs, and intestines. Stethoscopes are also used to detect Korotkov sounds when measuring blood pressure, helping determine systolic and diastolic blood pressure. The Riester stethoscope product portfolio offers a full range of options for auscultation in adults, children, infants, and newborns.

Product Usage Instructions

Indications

In medicine, trained clinicians use a stethoscope to assess tones and sounds that arise in connection with the activity of the heart, lungs and intestines. When measuring blood pressure, a stethoscope is used to detect the Korotkov sounds to determine systolic and diastolic blood pressure. Riester stethoscopes are used on adults, children, infants and newborns. The stethoscope is used in cardiology/general medicine to diagnose diseases and assess their course. Cardiac auscultation is part of the physical examination and is used to record physiological heart tones and to detect pathological heart murmurs that may be present. Indicating pathological changes in heart valves, for example. When auscultating, it is advisable to simultaneously palpate the pulse at the ra-dial artery, so that a possible pulse deficit (discrepancy between heart rate and pulse rate, e.g. in the context of arrhythmia, cardiac insufficiency or vascular stenosis), as well as the definitive classification of a systolic or a diastolic mur-mur, can be determined. Lung auscultation is used to detect breathing sounds and secondary breathing noises that arise in the thoracic region. Auscultation is usually done with a stet-hoscope. It is part of the physical examination. Lung auscultation makes it possible to detect pathological changes in the lungs with simple means and thus obtain signs and symptoms leading to further dia- gnostic measures. In the stethoscope tube, a column of air is created between the membrane of the chestpiece and the eardrums, which transmits the sound directly from the membrane to the eardrums. The ear tips attached to the head section seal the ear canal and prevent the sound waves from escaping and noise from entering. The sound amplification is achieved by a funnel embedded in the chestpiece. In the case of stethoscopes with a double-headed chestpiece, the chestpiece can be rotated by 180°. In addition to the diaphragm, there is a bell without a diaphragm. It enables better perception of lower frequencies, which can be particularly use-ful in cardiology. Special chestpiece construction makes it possible to isolate different frequency ranges by modifying the contact pressure of the membrane. When pressed light-ly, the lower frequencies are emphasised; when pressed harder, the higher-fre-quency sound waves are emphasised.

Device function
All stethoscopes manufactured by Rudolf Riester have the same basic structure. The stethoscope consists of four elements:

Tubing
Binaural tubes
Ear tips
Chestpiece

Operation and function

Symbol identification

cardiophon 2.0, duplex® 2.0, duplex® 2.0 baby, duplex® 2.0 neonatal: The opened diaphragm outlet can be recognized immediately by the marking on the tubing connection above.

Startup

Low/high frequencies:

duplex®, duplex® baby, duplex® neonatal, tristar®, ri-rap®:
Rotating the chest piece selects the diaphragm side (high frequencies) or the bell side (low frequencies). It is essential to ensure good surface adaptation during auscultation. When mea-suring blood pressure, the chestpiece can be partially pushed under the cuff with the diaphragm side down. You can immediately see which side is active from the closed/open bell outlet. After putting on the Binaural tubes, you can recognize acoustically whether the diaphragm is active by gently tapping the diaphragm. With the ri-rap® model, the small diaphragm side can optionally be converted into an open bell. The different bell sizes can be found in the enclosed spare parts list.

Adjusting/putting on the Binaural tubes
duplex®, duplex® baby, duplex® neonatal, tristar®, anestophon®, ri-rap®:

Please ensure that the Binaural tubes are set to the anatomically correct angle, i.e. they are to be worn so that they point slightly forward (see Fig.A). Riester-6165-Diagnostic-Stethoscopes-Instructions-
fig-6

The angle can be adjusted individually by rotating the Binaural tubes. The ear tips are correctly positioned when they are perfectly aligned with the external audito-ry canal which optimally prevent distracting external noise. The soft Riester ear tips are particularly suitable for this. If the contact pressure of the Binaural tubes is too strong or too weak, proceed as follows: If the contact pressure is too weak, press the two Binaural tubes together, as shown in Fig. B. If the contact pressure is too strong, spread the two Binaural tubes apart, as shown in Fig.C.

cardiophon 2.0, duplex® 2.0, duplex® 2.0 baby, duplex® 2.0 neonatal

The Binaural tubes are anatomically correctly set at the factory; their contact pressure is individually adjustable (Figs. B and C), the ear tips are rotatable and made of an extra-soft material. Overall, this achieves a perfect seal of the ear ca-nal against external noises, and prevents noise from the ear tips rubbing against the ear, even while the stethoscope is moving. The ear tips must not penetrate too far into the ear canal!

Replacing diaphragms

duplex®, duplex® baby, duplex® neonatal, tristar®, anestophon®, ri-rap®:
duplex®, duplex® baby, duplex® neonatal, tristar®, anestophon®, ri-rap®: To change the diaphragm, take the non-chill rim between your thumb and fo-refinger and pull it off the chestpiece. Place the non-chill rim with the flat side down on a flat surface and insert the diaphragm into the non-chill rim with the printed side facing up. Take the non-chill rim with the diaphragm and press it onto the chestpiece. With the ri-rap® chestpiece, the diaphragm is inserted into the threaded ring and the threaded ring is screwed back on. In the case of diaphragms with a cur-vature, this should point outwards, away from the ri-rap® chestpiece.
cardiophon 2.0, duplex® 2.0, duplex® 2.0 baby, duplex® 2.0 neonatal To change the diaphragm, take the non-chill rim between your thumb and fore-finger and pull it off the chestpiece. Place the new diaphragm with the printed side up centered in the opening of the chestpiece, then place the non-chill rim in the centered position and press it back onto the chest piece with your thumbs in a semicircular movement. Please ensure that the diaphragm remains centered in the opening and is not shifted.

Care Instructions

General Information
The cleaning and disinfecting of medical devices serves to protect the patient, user, and third parties, and to maintain the value and function of the medical device. The product design and materials used make it impossible to define an upper limit on max. feasible treatment cycles. The service life of medical devices is determined by their function and proper handling. Before return for repair, defective products must have undergone the prescribed reprocessing procedure. If a reusable device shows signs of material deterioration, it should no longer be used and should be disposed of/claimed according to the procedures described in the disposal/warranty sections.

Cleaning and disinfection
To avoid possible cross-contamination, the stethoscope must be cleaned and disinfected regularly. The outside of the device can be cleaned with a damp cloth (if necessary, moiste-ned with alcohol) until they are visually clean. Use disinfectants (e.g. disinfectant Bacillol AF by the company Bode Chemie GmbH / time 30s) only as per the manufacturer‘s specifications. Only disinfectants with proven effectiveness according to national directives should be used. After disin-fection, please wipe the devices with a damp cloth to remove any residual disinfectant. Please make sure that the cloth is moistened, NOT wet, to prevent moisture from entering the device openings. For this, the non-chill rims and membrane(s) must be removed from the chest-piece. Take the non-chill rim between your thumb and forefinger and pull it off the chestpiece. The loose membrane can then be removed from the chestpiece. With the ri-rap® chestpiece, the threaded rings are unscrewed for this. For thorough cleaning and disinfection of the ear tips, these can be pulled off (unscrewed in the case of the ri-rap). For thorough cleaning and disinfection, you can use 70% isopropyl alcohol or soapy water to wipe the chestpiece, the non-chill rims the membrane(s), the ear tips and Binaural tubes with tubing. After cleaning and disinfection, the parts must be dried thoroughly before as- sembly. Then attach or screw the ear tips back onto the Binaural tubes. duplex®, duplex® baby, duplex® neonatal, tristar®, anestophon®, ri-rap®: Place the non-chill rim with the flat side down on a flat surface and insert the diaphragm into the non-chill rim with the printed side facing up. Take the non-chill rim with the diaphragm and press it onto the chestpiece. With the ri-rap® chestpiece, the diaphragm is inserted into the threaded ring and the threaded ring is screwed back on. In the case of diaphragms with a curvature, this should point outwards, away from the ri-rap® chestpiece. cardiophon 2.0, duplex® 2.0, duplex® 2.0 baby, duplex® 2.0 neonatal: Place the diaphragm with the printed side up centered in the opening of the chest piece, position the non-chill rim correctly, and press it back onto the chestpiece with your thumbs, each in a semicircular motion. Please ensure that the dia-phragm remains in its opening and is not off-center. When using 70% isopropyl alcohol, ensure the room is well ventilated! Do not use in the vicinity of fire-triggering devices or fire. Regularly clean and disinfect the ear tips and check for free passage. Never place the stethoscope in liquids! The item is not approved for machine reprocessing and sterilisation. This will lead to irreparable damage! Phenol-based disinfectants must not be used to clean and disinfect the stet-hoscopes. The pH of the treatment solution used must be between 4.5 and 10. Never use stethoscopes without ear tips/diaphragms!
