Simple questions: what is the name of the "slushalka" doctors?

Today, the doctors to diagnose the patient may resort to a variety of laboratory studies and other diagnostic options. Unfortunately, even 100 years ago, doctors were not and a tenth of the devices that they can use now. However, in the early 19th century there was a special tube to listen to heart and breath of the patient. However, then very few people knew what the name "slushalka" the doctors, and understood how it works. But this simple device in some cases helps the doctor to determine exactly what is bothering the patient.

History

For the First time in 1816 to take advantage of something like the modern stethoscope has decided the French physician Rene Laennec the examination of one of the noble ladies. As he later recalled, because of age, sex and completeness of women he could not accurately diagnose. Easy attachment of the ear to the chest did not give any results. Then Laennec decided to just roll up the sheets of paper. It helped him to determine she has cardiac arrhythmia.

Later, folded sheets of paper replaced the tube, narrow in the middle and having extensions at both ends. The one is wider and follows the shape of the ear. This allows doctors to more clearly hear the noises in the lungs and heart tones. The stethoscope - that's what is called "slushalka" the doctors of those times. His modern look, as the title suggests, a stethoscope got closer to the 20th century. One of the first to use it to diagnose an outstanding Russian surgeon Nikolai S. Korotkov.

Structure of modern stethoscope

A Stethoscope, a photo of which is above has 3 main parts: the head with the membrane, which amplifies sounds, a conductive tube and olive trees-tips for the ears of the doctor. Its main advantage is that, unlike the stethoscope, it allows you to listen to higher frequencies, which makes it indispensable in pulmonology. However, for more accurate diagnosis, doctors need to listen to low frequency sounds. Therefore, later there a device that combines the properties of both devices. On one side of the tip has a membrane, and on the other hand - no. Thus, the correct answer to the question of how is called "slushalka" the doctors, - the phonendoscope. Even though the doctors themselves, this term is rarely used, reducing it to the more familiar - the stethoscope.

So, during this time, many people were able to appropriate and timely treatment. It is much more important than the knowledge of any of the terms.
