Duplex Stethoscope w/grey tubing "Yamasu"

Clinical Application

The duplex configuration provides two acoustic interfaces for systematic auscultation in perioperative and clinical settings. The diaphragm side is used to detect higher-frequency sounds such as breath and certain heart sounds, while the bell side improves pickup of low-frequency signals such as some murmurs and vascular/bruit assessment. Common uses include pre- and post-operative assessments, intraoperative spot checks by anesthesia providers, PACU and ICU monitoring, and routine clinic or bedside evaluations.

Design & Configuration

The instrument's dual-head chestpiece gives clinicians immediate access to both diaphragm and bell without changing instruments, enabling quicker transitions between high- and low-frequency listening. The binaural headset is angled for an anatomic fit to the ear canals to improve acoustic transfer and reduce ambient noise. Grey tubing offers a neutral color option for clinical environments and helps with visual organization of supplies.
