diaphragm The diaphragm is the circular end of the chestpiece. On two-sided chestpieces, the diaphragm is the larger of the two ends. Its larger size allows the user to listen to a bigger area of the patient’s body. The diaphragm is designed to pick up sounds with higher frequencies compared to the bell.
To remove, pull firmly on the eartip. On Littmann stethoscopes with traditional combination chestpieces, it is necessary to open the side of the chestpiece being used. This is accomplished by holding the chestpiece stem in one hand and rotating the chestpiece with the other hand until a click is felt.
Do not bend or contort the tubing of your stethoscope, as this can cause tearing in the PVC. One of the most common ways that this happens is by stuffing a stethoscope in your pocket, so try to avoid this practice. The tubing is one of the most fragile parts of your stethoscope, and as a result is most prone to damage.
- Apply a liberal amount of rubbing alcohol, acetone or commercial stain remover to a clean cloth. Use nail polish remover in place of acetone, as long as the label indicates it is acetone-based.
- Rub the marker stain vigorously.
- Clean the surface with soapy water once the stain is gone to remove residue from the solvent.

about every two years Stethoscope manufacturers recommend for the device to be replaced about every two years, but medical professionals remain wary about this advice. For optimal use, people should be on the lookout for signs the device has worn down through extended use.Nov 25, 2020
Sun damage can crack your stethoscope as direct sun exposure makes the tube hard, which is easy to break. The stethoscope absorbs the UV rays from the sun leading to degradation. The residues broken down by the UV rays on the stethoscope will act as receptors that further damage the device.Mar 27, 2021
Tubing. Most stethoscopes come in 22-inch or 27-inch tube lengths. Shorter tubing, in theory, offers better sound volume, but the human ear does not detect the difference in acoustical performance between a stethoscope with shorter tubing versus one with longer tubing.Aug 16, 2019
Acoustic tubes: The acoustic tubes are the hollow rubber-like tubes that connect the chestpiece to the ear tubes. Headset: This is typically the metal portion of the stethoscope. Ear tubes: The ear tubes are hollow metal tubes that connect to the acoustic tubes on one end and the earpieces on the other.
