Setup and Assembly
The Sprague Rappaport stethoscope offers versatility through its interchangeable chestpiece components. Follow these steps to set up your stethoscope:
- Attach Eartips: Select a pair of eartips that provide a comfortable and secure fit. Gently push them onto the binaural tubes until they are firmly seated. Ensure a tight seal to prevent sound leakage.
- Adjust Binaurals: The binaural tubes are designed to be angled forward, aligning with the ear canals. Gently adjust the tension of the binaurals by pulling them apart or pushing them together until they fit snugly but comfortably in your ears.
- Select Chestpiece Attachment:
- For high-frequency sounds (e.g., lung sounds, adult heart sounds), attach one of the diaphragms.
- For low-frequency sounds (e.g., some heart murmurs, bowel sounds), attach one of the open bells. Choose the appropriate size (adult, medium, or infant) based on the patient.
- Activate the Desired Side: The Sprague Rappaport chestpiece is dual-sided. To activate the desired side (diaphragm or bell), rotate the stem 180 degrees until you hear a click. The side that is open to the tubing will transmit sound.

Operating Instructions
Using your Omron Sprague Rappaport Stethoscope effectively requires proper technique:
- Position Eartips: Insert the eartips into your ears, ensuring they point forward, aligning with your ear canals. This provides the best acoustic seal and comfort.
- Check for Sound: Lightly tap the diaphragm or bell you intend to use. You should hear the tapping sound clearly. If not, rotate the chestpiece stem 180 degrees until the active side is engaged.
- Auscultation:
- Diaphragm: Place the diaphragm firmly against the patient's skin to listen to high-frequency sounds such as heart sounds (S1, S2), lung sounds, and bowel sounds.
- Bell: Place the bell lightly against the patient's skin to listen to low-frequency sounds such as some heart murmurs (S3, S4) and bruits. Avoid pressing too hard, as this can stretch the skin and turn the bell into a diaphragm, filtering out low frequencies.
- Minimize External Noise: Perform auscultation in a quiet environment to ensure accurate listening.

Care and Maintenance
Proper care ensures the longevity and hygienic use of your stethoscope:
- Cleaning: After each use, wipe the diaphragm, bell, and eartips with an alcohol wipe (70% isopropyl alcohol) or a mild soap solution. Ensure all surfaces are dry before storage.
- Tubing Care: The latex-free tubing can be cleaned with alcohol wipes. Avoid immersing the tubing in liquid or using harsh chemicals, which can degrade the material.
- Storage: Store your stethoscope in a clean, dry place, away from extreme temperatures, direct sunlight, and solvents. Avoid coiling the tubing tightly, as this can cause kinks and reduce its lifespan.
- Inspection: Regularly inspect the eartips, diaphragms, and bells for cracks, tears, or wear. Replace any damaged components to maintain optimal acoustic performance.
Troubleshooting
If you experience issues with your stethoscope, consider the following common solutions:
- Poor Sound Quality or No Sound:
- Ensure the chestpiece is rotated to activate the desired side (diaphragm or bell).
- Check for blockages in the eartips or tubing. Remove and clean eartips if necessary.
- Verify that the eartips are securely attached and form a tight seal in your ears.
- Inspect the diaphragm or bell for cracks or loose connections. Replace if damaged.
- Uncomfortable Eartips:
- Try the alternative pair of eartips provided to find a more comfortable fit.
- Adjust the tension of the binaurals for a snug but not overly tight fit.
- Tubing Kinks:
Store the stethoscope loosely coiled to prevent permanent kinks in the tubing.
