While most consider the added weight of stainless steel or titanium a worthwhile tradeoff for superior performance, others find these materials too cumbersome to comfortably carry around all day.įortunately, there are plenty of quality lightweight stethoscopes available. Unfortunately, the same materials that provide the best acoustics and durability also add extra weight to a stethoscope. Size, adjustability, and angle are also important considerations, as an uncomfortable headset will only serve as a distraction.īestReviews Medical Expert Stethoscope weight Other vital stethoscope parts HeadsetĮnsuring that the binaurals (ear tubes) are constructed from the same high-quality materials as the chestpiece is crucial for accurate sound transmission. A neonatal stethoscope will have an even smaller diaphragm than a pediatric stethoscope, which allows you to better hear with preemies and infants. These stethoscopes allow you to hear higher-frequency sounds and have smaller diaphragms. This design is considered by many to yield optimal overall sound quality. Others actually prefer it.Ī stethoscope with bi-lumen single tubes features two tubes molded into one casing to prevent rubbing. For some, the “split” quality of a single sound source is insufficient. While this design works for some, the tubes can be prone to rubbing against one another, causing considerable interference.Ī stethoscope with a single tube has a tube that runs from the chestpiece and splits into two at the earpieces. Each tube is independently connected to each earpiece. You’ll need to decide whether you’d prefer double tubes, a single tube, or a bi-lumen single tube.Ī stethoscope with double tubes features two separate tubes, just as the name suggests.

However, many physicians opt for PVC as it not only reduces the risk of skin irritation but also offers better durability. Both PVC and latex rubber are commonly used materials. Thin, flimsy tubes will easily pick up external sounds and are more likely to produce distortion or lose signal. When it comes to tubing, thick and durable construction is a must. Tubing construction, length, and style Construction In terms of patient comfort, most chestpieces come with a non-chill rim that not only helps to form a seal but also goes a long way toward ensuring your patient’s consultation is a pleasant, gasp-free experience. But, be warned: the same high-density materials that offer improved clarity may also add considerable weight. Materials such as titanium or stainless steel with a smooth, well-finished interior and exterior generally provide superior performance. While the chestpiece design is largely a matter of preference or, in some cases, intended application, most agree that the quality of its overall construction is non-negotiable. While not quite as versatile as a dual-head chestpiece, the single-head tunable diaphragm usually offers improved clarity and amplification, especially when used to listen to heart sounds.īestReviews Medical Expert Chest piece construction This type of chestpiece is most commonly used by cardiologists and features a one-sided, tunable diaphragm that allows for auscultation of both high and low frequencies by simply adjusting pressure. While stethoscopes themselves certainly aren't all that complicated, the various elements that go into making a good stethoscope can be difficult to identify when you're unsure of what you're looking for.
These vibrations are then funneled through the narrow tubing directly to our ears, resulting in effective amplification. In the case of traditional dual-head stethoscopes, this can be achieved by using either the wide, drum-like surface of the diaphragm (which collects vibrations directly from high-frequency sounds) or the smaller concave bell (which picks up vibrations on the skin caused by low-frequency sounds). Buying guide for How stethoscopes workĪt their most basic, stethoscopes work by picking up the vibrations caused by a variety physiological functions via the chestpiece, then transmitting them to our ears through the airtight tubing and headset. Taking enough time to practice using your new instrument is essential. Getting accustomed to the feel of a new stethoscope may take a while.
