HOW TO USE STETHOSCOPE LITTMANN CLASSIC

If you stay in Hospital you'll see a stethoscope littmann classic the neck almost in every doctor.However, this wonderfully useful instrument had its origins not in science, but in modesty.
Back in 1800, doctors used to check the heart by simply putting an ear on the patient's chest. However, that was embarrassing . So in 1817, Rene Laennec began using a hollow wooden tube for the task. And by the early 1900s, the stethoscope had evolved into its present form with rubber tubes and a metal bell on the end.
Your doctor's stethoscope litmann classic is a simple device that nevertheless gives him or her crucial information about your heart. First your doctor listens for two sounds--a "lub," followed by a "dub." The "lub" is the sound of the first set of heart valves closing; the dub is the second set closing. In-between the lub and dub, the heart should be quiet. If it isn't, there might be a problem. That's how to use stethoscope littmann classic.
Besides listening for these sounds, your doctor is also listening for how steady or regular that lub-dub is by using stethoscope littmann classic. If it skips or jumps, you have an irregular heart rate. This irregularity can indicate a problem. In many cases, however, it is not dangerous to you.

STETHOSCOPE INVENTOR

RenĂ© Laennec  invented the stethoscope in 1816. While consulting a female patient, Laennec needed to listen to the woman’s chest. Before the stethoscope, doctors would place their ear directly onto the patient’s chest, a practice called auscultation. As the patient was somewhat overweight, Laennec thought it both improper and inadequate to place his head on her chest and listen directly. He rolled up a sheet of paper into a tube and placed one end on the patient’s chest. The tube magnified sound, and Laennec found he could hear her lung sounds easily by putting his ear to the open end. The rolled up piece of paper was soon replaced by a hollow wooden tube. Laennec named his invention the ‘stethoscope’

By the 1850s, the stethoscope had become one of the doctor’s vital tools. Learning to listen and diagnose the sounds from the chest became an important part of a doctor’s training.

In the 1890s, the hollow wooden tube was replaced by the rubber and now plastic, binaural stethoscope, much like stethoscopes that are used today. These stethoscopes have two ear pieces and a bell-like end that is placed on the body. Stethoscopes are not only used to listen to the chest but also other parts of the body such as the bowels and during pregnancy. Electronic stethoscopes that amplify the sounds in the chest and produce graphs were first produced in the 1970s and continue to be refined. Today, a stethoscope around the neck is one of the most popular images of the medical profession.

THE BEST STETHOSCOPE FOR YOU

Stethoscope Littmann is the most popular brand. Stethoscope Littmann has captured the stethoscope market in many countries. Of course, the Littmann's mentioned above are good. I have even used the Classic II. However they are certainly not the best stethoscopes.

The stethoscope traditionally used is the Sprague, developed more than 45 years ago. It is still considered to be the gold standard acoustic stethoscope, with an outstanding high to low range.  However, that being said, once you have learnt to recognize what is simply the tube sound, you'd be hard pressed to get better acoustics from any scope.

As a medical student, I owned a Littmann. However, when that got lost, for a time I used a Sprague I'd borrow from my seniors (all Cardiology fellows, and many med residents, at my institution own Spragues). I felt this was definitely a superior scope. Which in my personal opinion is the best acoustic scope out there.

The "traditional" scopes like the Spraguewere built in an era when bedside diagnosis was of paramount importance in medicine. I feel has helped me over the years to sharpen my clinical skill - you are forced to learn and understand the characteristics of each murmur, gallop, HS, etc... where's the best place to look for them, how they sound, their frequencies, their timing, what accentuates the murmur. I've noticed people who use the Littman just use the flat d - the claim is the patented "Littmann diaphragm" automatically turns into a bell if you release pressure on it. think this has lead to a certain laziness in many students - they don't take the trouble to properly learn cardiac sounds, and correlate what they learn in the books with what they hear in clinical practice. Because they don't hear much. Which in turn can discourage learning and correlating. It's a vicious cycle. It is not helped when they are taught by a generation of physicians who have themselves lost the art and skill of bedside diagnosis, and for whom the exam isn't important - only the thousand dollar test.

HOW TO USE STETHOSCOPE PROPERLY

Get the Right Eartip Size
For optimal acoustic performance, it’s important to use the eartip size that best fits your ear. This is especially true when using the soft-sealing eartips. All eartips are available in small and large.
Remove Possible Obstructions
If you usually carry your stethoscope in a pocket or don’t clean it often, lint or dirt may accumulate and obstruct the sound pathway. To prevent debris from accumulating, give your stethoscope routine cleaning and care.
Check the Seal
Stethoscopes rely on an airtight seal in order to transmit body sounds from the patient to the practitioner’s ears. Loose parts in the chestpiece, loose tubing, or cracked tubing can prevent an airtight seal.

Open the Bell

When using a double-sided stethoscope, you need to open (or index) the bell or diaphragm by rotating the chestpiece. If the diaphragm is open, the bell will be closed, preventing sound from coming in through the bell, and vice versa.
3M™ Littmann® Stethoscopes are known for first-class sound quality and comfort. But there are some simple things you can do to ensure the performance and wearability of your new scope.

Align the Headset

Before placing the eartips in your ears, hold the headset in front of you with the eartubes pointing away 
Once the eartips are in your ears, they should point forward

If the fit still isn’t comfortable, and/or acoustic performance is lacking, grasp each of the eartubes and adjust the headset for a custom fit.
Wearing the headset improperly can result in a poor acoustical seal and in some cases, complete sound blockage.

DAVID LITTMANN STETHOSCOPE BRAND


David Littmann, M.D., (07/28/1906–1/1/1981) was an American cardiologist born in Chelsea Massachusetts( born to Ukrainian immigrants from Novogrod Wolyn aka Zwill Ukraine formally the Russian Empire, Issac Litman and Sadie Zewat Litman and Harvard Medical School professor and researcher. The name Littmann is well known in the medical field for the patented Littmann Stethoscope reputed for its acoustic performances for auscultation.

With Gus Machlup, Dr. David Littmann founded Cardiosonics, Inc. to sell his stethoscopes. At that time the stethoscope line consisted of two key models, the doctor's stethoscope and the nurse's stethoscope.

3M acquired the stethoscope company on April 1, 1967, and hired Dr. Littmann as a consultant. 3M currently produces the range of Littmann brand stethoscopes.

THE HISTORY OF STETHOSCOPE

Stethoscope was found by RenĂ© Laennec from France in 1816. He invented while he worked at Necker-Enfants Malades Hospital in Paris. The first ever stethoscope used a wooden tube and was monaural, similar with common ear trumpet. In that day, his invention was not called a stethoscope yet, but commonly called a "microphone". 
the history of stethoscope
the modern stethoscope

 Golding Bird was made the first flexible stethoscope in 1840. Bird was the first to publish a description of such a stethoscope but he noted in his paper the prior existence of an earlier design which he described as the snake ear trumpet. Bird's stethoscope had a single earpiece.
 In 1851, Irish physician Arthur Leared invented a binaural stethoscope, and in 1852 George Cammann perfected the design of the instrument for commercial production, which has become the standard ever since.

Rappaport and Sprague made a new stethoscope design in the 1940s, and became the standard, consisting of two sides, one of which is used for the respiratory system, the other for the cardiovascular system.  The Rappaport-Sprague model stethoscope was heavy and short (18–24 in (46–61 cm)) with an antiquated appearance recognizable by their two large independent latex rubber tubes connecting an exposed-leaf-spring-joined-pair of opposing "f"-shaped chrome-plated brass binaural ear tubes with a dual-head chest piece.

David Littmann, a Harvard Medical School professor, in early 1960 created a new stethoscope that was lighter than previous models. In the late 1970s, 3M-Littmann introduced the tunable diaphragm: a very hard (G-10) glass-epoxy resin diaphragm member with an overmolded silicone flexible acoustic surround which permitted increased excursion of the diaphragm member in a "z"-axis with respect to the plane of the sound collecting area. The left shift to a lower resonant frequency increases the volume of some low frequency sounds due to the longer waves propagated by the increased excursion of the hard diaphragm member suspended in the concentric accountic surround.
