Tunable Diaphragm – the Heart of the Lightweight II S.E. Stethoscope

The unique shape of the chestpiece also allows easy navigation around blood pressure cuffs and bandages. This stethoscope is a useful diagnostic tool for blood pressure and limited physical assessment in adult patients and its light weight and tunable diaphragm make it an ideal choice for certified nursing assistants, licensed practical nurses, EMT/EMS, licensed vocational nurses, medical assistants and nursing students. Littmann® tunable diaphragm technology offers reliable and clear acoustics, versatility and time-saving convenience. Switching between bell and diaphragm modes is as easy as a simple pressure change on the chestpiece. There is no need to remove, index and replace for same-site auscultation. Resilient tubing folds tightly for pocket portability and retains its shape while patented Snap Tight Soft-Sealing Eartips help form an effective acoustic seal. The anatomically correct headset is angled to channel sound and enhance listening comfort while the nonchill rim and diaphragm provide patient comfort. The Lightweight II S.E. is made in the USA. The product and package are latex-free.

What are Stethoscopes?

Stethoscopes are diagnostic instruments that amplify sounds made by the body from the heart, lungs, abdomen and intestinal tract, or other body sites. A stethoscope is used to detect and study internal systems, such as fetal development, blood flow or blood pressure (BP), and respiration, and sounds, such as cardiac, venous, arterial, pulmonary, and uterine. Stethoscopes typically have Y-shaped rubber tubing that allows sound to travel from the chestpiece to the eartips. An open bell detects low frequency sounds, and a diaphragm detects high frequency sounds. A stethoscope can come as single, double (dual), or triple-head. Binaural stethoscopes are used with both ears, and single stethoscopes work with one ear. Differential stethoscopes are double-head, and allow sound comparison between different body sites. Non-electronic, also called mechanical or acoustic stethoscopes, transmit sound through hollow tubing to a listener’s ear. Stethoscopes are used by students and a wide array of healthcare providers including physicians, nurses, and veterinarians, as well as specialists such as cardiologists, pediatricians, gastroenterologists, pulmonologists, and respiratory professionals in hospital, clinical, or other healthcare facilities.
