Doctor's Littmann 3M™ Littmann® 5811 Classic III™ Stethoscope

3M™ Littmann Classic III is the latest version of the stethoscope, helps millions of doctors achieve the best performance. The Classic III stethoscope features high acoustic sensitivity for exceptional performance, as well as a versatile dual-sided chest piece and adjustable membranes. Used by students and doctors alike to identify sounds of the heart, lungs, and other body sounds, listen to them, study them, for physical assessment purposes, patient monitoring, and diagnosis. The adjustable diaphragm technology - invented by 3M - enables doctors to hear sounds of different frequencies by simply adjusting the pressure on the chest piece. Hold the chest piece with light pressure to hear low-frequency sounds, and press a little more to hear higher-frequency sounds. This time-saving feature allows the healthcare provider to focus on the patient, while the comfortable diaphragm provides comfort to the patient. The headband can be easily adjusted to fit the head size and comfort by pressing the earpipes together or apart. The snug and soft ear tips fit each ear individually, providing excellent sound isolation and a comfortable fit. The ear tips are firmly attached to the ear pipes, and for safety reasons, removing them requires significant effort. The new generation flexible tubes maintain their shape and flexibility even after being tightly folded and placed in a pocket. They also extend the life of the stethoscope thanks to improved resistance to skin oils and alcohol, and are less prone to staining. The new generation tubes are not made from natural latex rubber, which benefits highly sensitive doctors and their patients. To ensure human health and environmental protection, the new generation tubes are free of phthalates. The Classic III stethoscope is made in the USA to ensure consistent quality. Comes with large and small snug ear tips, a cold-resistant jelly cover, and a user manual. A dual-sided chest piece with adjustable membranes on both sides for adults and children. The adjustable single-piece diaphragm is easy to install and easier to clean because its surface is smooth and without cracks. The child side can be converted to a traditional open bell by replacing the single-piece diaphragm with the included non-cold edge. The new flexible tubes have a longer lifespan due to improved resistance to skin oils and alcohol; they are less prone to staining. The small adjustable diaphragm is useful for pediatric or small or thin patients; around dressings; and for carotid artery assessment. More than twice the sound of the next leading stethoscope. Allows more reliable and consistent listening to heart sounds at low frequencies (less than 120 Hz*) such as Korotkoff sounds, mitral stenosis, and S3 and S4 Gallops compared to other leading stethoscopes. Weighs less** than other medical stethoscopes. Five-year warranty on this product includes free repairs during this period for any manufacturing or material defect.

The larger and tighter single-piece diaphragm sets increase sound sensitivity.
