Littmann - 听诊器大师心脏病学黑烟完成 - NSL-2176

3M Littmann Master心脏病学听诊器，烟雾版，27英寸，2176

The 3M Littmann Master Cardiology Stethoscope features tunable diaphragm technology — 3M invention — that lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two-sided models, there’s no need to turn over and reposition the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time-saving feature allows the healthcare provider to focus on the patient, while the non-chill rim provides patient comfort.
