MDF® 727 Single Head Stethoscope
(Also for MDF® 727C and MDF® 757)


Read instructions carefully before using and save for future reference.


General Safety: This MDF® stethoscope is designed exclusively as a non-invasive medical auscultation instrument for the detection of heart and lung sounds on healthy skin around the external thoracic region. Due to its sound amplification function, it may cause damage to user’s ears if used other than its intended medical diagnostic purpose. Use only if you are a medical professional and do not leave stethoscope unattended around children.


General Usage: MDF® stethoscope headsets are anatomically adjustable for best fit, comfort, and sound transmission. A headset adjusted to a 15° forward angle is standard, and should be worn with the eartips pointed away from you if it is held directly in front of you.


General Cleaning & Care: Clean stethoscope thoroughly before each use. For chestpiece, acoustic tubing, and ComfortSealTM eartips, use clean cotton cloth or swab and rubbing alcohol or isopropyl alcohol solution to cleanse all soiled parts. Avoid prolong exposure of the acoustic tubing to excessive heat, cold, solvents, moisture, or oils/lipids (secreted by human skin).


Our commitment to high-quality instruments is backed by a lifetime warranty.
