A stethoscope is an acoustic medical device used by healthcare professionals to examine their patients to listen to the internal sounds of their bodies. This medical equipment generally consists of a headset, tubing and a sensor. The headset represents the metal part having two ear tips. The chestpiece is the sensor the doctore places on the patient's skin. The tubing is finally this flexible tube which connects the heaset to the chestpiece.
Placemed offers you in this section a wide choice of stethoscopes: adult, child, single or double sided chestpiece. From the biggest brands, our selection includes electronic models, classic models with single or double tubing, models with single or double sided chestpiece. All these models have been selected for their quality and performance in order to best meet the needs of all healthcare professionals in terms of stethoscopy.
It is very difficult today to imagine healthcare professionals, especially doctors, without a stethoscope. It is a simple and versatile tool that can be very useful in a medical diagnosis. It is an acoustic device used to listen to internal sounds emitted by the patient's body during auscultation.
The fascinating history of this instrument began in 1816 with the French doctor René Laënnec. To improve listening to the internal noises of his patients, René Laennec initially used a system based on bundles of rolled papers which he then adapted by developing a wooden model in the form of a hollow tube. Structurally, this model was very simple. It is made of a hollow wooden tube, not very long and thick enough, and the auscultation was monaural, that is to say, it was performed with one ear. The technique used by Laennec thus presents important differences compared to modern stethoscopes, but it remains fundamental in the contemporary stethoscopy. The binaural model appeared in 1851 with the American George Kamman. The switch to binaural did not popularized quickly. It was until the beginning of the 20th century for the binaural model to be popularized, and till the beginning of the last century for it to begin supplanting the monaural model. And since the advent of binaural medical stethoscopes, the design of this medical instrument has not undergone any significant changes. The modern stethoscope consists of a headset, a tubing (acoustic tube) and a chestpiece (bell with sensor).
The headset is the part that allows the doctor to listen to the patient. It consists of two eartips (ear plugs) and an eartube with spring. Stethoscope tubing can be made of soft rubber or hard plastic. Some stethoscopes can be made from both materials and come in several sizes. A good headset should be both tight to the ears and easy to remove. Tubing, on the other hand, is generally designed as a conductive acoustic tube measuring between 65 and 70 cm in length. And the chestpiece is made up of an acoustic membrane and sometimes and diaphragm. This is truly an essential component on which sound quality largely depends.
Today, the medical device market is teeming with stethoscopes, including electronic, cardiologic, nursing, pediatric models. Their acoustic properties differ considerably. It is therefore important not only to choose a model of superior acoustic quality, but also to you should define your business needs according to your professional specialization.
