Description of Stethoscope Parts

The parts of the stethoscope are designed for the comfort of the user, the comfort of the patient, and to efficiently hear internal body sounds in the lungs, heart, and other areas.

  1. Binaural Tubes

    • The lower binaural tubes are two movable metal prongs which attach to the tubing and allow the stethoscope to be positioned in both ears.

    Ear Tips

    • The ear tips, located at the two upper ends of the binaural tubing, should be placed in the ear canal facing forward to maximize the user's ability to hear sound.

    Tubing

    • The tubing allows sound to transmit up through the ear tubes and is made from a flexible material, often neoprene or another similar material. The lower part of the tubing attaches to the stethoscope head and the upper part attaches to the binaural tubes.

    Chestpiece or Stethoscope Head

    • This is the metal part of the stethoscope that allows sound to be heard. Stethoscope heads can be double or single-sided and the shape of a side or the amount of pressure applied makes it easier to listen to certain sound pitches and frequencies.

    Chill Ring

    • The chill ring is a thin ring that holds the head in place and provides protection to the patient's skin when the head is against it.
