3A – Stethoscope NSL – Heartplus PS-200

Riester – Stethoscope Black Edition Duplex is an acoustic medical device used for auscultation, or listening to the internal sounds of the human or animal body. It features a small disc-shaped resonator placed against the chest, connected to two tubes leading to earpieces. It is commonly used to assess lung and heart sounds, as well as intestinal activity and blood flow in arteries and veins. When paired with a sphygmomanometer, it is a standard tool for measuring blood pressure.

There are also specialized versions such as mechanic’s stethoscopes, which use rod-shaped chest pieces to detect internal mechanical sounds in machines, for example diagnosing problems in automobile engines by listening to vibrations and internal component noise. Stethoscopes can also assist in detecting leaks in scientific vacuum chambers and other small-scale acoustic monitoring tasks. A type that amplifies body sounds is known as a phonendoscope.

Stethoscopes have become a symbolic representation of healthcare professionals, often seen worn around the neck by practitioners. Research has suggested that, compared with other medical tools, stethoscopes create a strong impression of trustworthiness.

With the rise of portable ultrasonography in the late 1990s and early 2000s, some experts predicted that stethoscopes might eventually become obsolete. Others believed that while new digital tools would change medical practice, stethoscopes would remain essential for many years. Even a decade later, opinions remained divided: some specialists claimed the stethoscope was outdated, while others insisted it would continue to hold value across many healthcare fields.

In practice, the importance of the stethoscope varies by specialty. It is still widely relied upon in primary care, pediatrics, emergency services, and physical therapy for evaluating lung and bowel sounds. In some advanced cardiology settings, however, traditional auscultation is considered less necessary due to modern imaging technologies. This suggests that certain specialties may reduce their reliance on stethoscopes sooner than others.
