Stethoscopes have been used for a long time to listen to the many sounds of the body. They are a totally innate piece of equipment for all doctors and health care practitioners and the examination of any patient will be incomplete without having a stethoscope. Stethoscopes can be used for people along with animals. Most commonly, this gadget is used to listen to the heart beats. But this really is only a small aspect of what they're intended for.
You will find basically 3 forms of stethoscopes that are manufactured for the use of doctors and other healthcare practitioners. Included in this are:
Traditional acoustic Stethoscopes: This is the most often used stethoscope, that features a standard chest piece, hollow rubber tubes, and twin ear pieces. These have whats called a dual chest piece given that they have a small bell cup on one aspect along with a diaphragm on the other half. Nevertheless, with such stethoscopes can generate problems when hearing faint noises or with these in places where there can be a loud atmosphere.
Electronic Stethoscopes: A much modern form of stethoscope, an electronic stethoscope is able to boost body sounds for the benefit of the listener. The acoustic waves are converted into digital signals, which are next increased and processed for enhanced hearing. As a result, these kinds of stethoscopes are fantastic for weak sounds and will be easily employed in any type of surroundings. Considering the surge in the use of the electronic stethoscopes it isn't impossible to say they'll one day be the most commonly encountered variety used.
Finally is the fetal stethoscope. Its unique structure enables you to pay attention to fetal cardiovascular system tones. These stethoscopes are also known as fetoscopes or pinards. On the other hand, with the breakthroughs in technological innovation a replacement for fetal stethoscopes continues to be developed. That is termed as the electronic digital sonaid and is now frequently used by physicians across the world.
And so recognized is a stethoscope that it is regarded with both the doctor or registered nurse.

Littmann Stethoscope
In 1963, Harvard School Of Medicine Professor David Littmann invented a stethoscope that would revolutionize the world of medical auscultation. Knowing that a 'one size fits all' approach to stethoscope technology and the proven fact that the basic stethoscope design had changed little in over a hundred years, he set out to find a solution. He engineered features that caused it to be more comfortable for someone to use the stethoscope. The quality of sound produced by the new design made such a profound step up from what had gone before that in 1967 the 3M corporation acquired Dr Littmann's company, Cardiosonics Inc.
As a world leader in health care products 3M went on to further improve and cultivate the Littmann stethoscope and and in 1978 worked very closely with leading figures in the medical profession to produce the 3M Littmann Cardiology Stethoscope. This became known as the "cardiologists dream stethoscope" and had both a dual tube design and the increased low frequency sound capability.
In the 1980's the engineers at 3M developed whats now known as the tunable diaphragm. The one pitfall with Dr. Littmann's brand-new design had been that you still had to lift the chest piece off the patient in order to switch between diaphragm and bell modes, this was eliminated with the tunable diaphragm. Accordingly the chest piece need not be moved to become optimized for different sound frequencies. This represented a significant breakthrough in the area of auscultation and in addition the fact that low frequency sounds were getting increased by a diaphragm as opposed to a bell meant that amplification was much greater and much clearer.
Technology is now enough where electronic stethoscopes are able to detect bodily sounds and letting them be heard up to 24 times higher. With all the digital versions you can download assessments onto a computer for additional evaluation. The Littmann distinctive line of stethoscopes enjoy a huge lead in relation to their competitors due to quality and first rate innovations.

How To Use A Stethoscope
Learning how to use a stethoscope isn't difficult. Stethoscopes are most commonly employed to take note of cardiac, lung and intestinal noises. They're not difficult to use, but understanding the interpretation of what you pick up takes much ability and training.
How To Use A Stethoscope - Clean off the ear buds before inserting the stethoscope into your ears, particularly if other people share it or perhaps you don't often use it. In the hospital, earpieces are easily wiped with alcohol prep swabs.
How To Use A Stethoscope - Hold the chest piece between your palms to warm it prior to placing it on the person's chest. Thirty seconds is generally long enough to remove the chill.
How To Use A Stethoscope - Once you have the ear pieces comfortably in the ear pathways, tap the diaphragm very gently with your finger tip to determine if the chest piece is indexed. If it's a dual head chest piece you will know if it is indexed once you clearly hear the tap of your finger against which ever side you're needing to use, either the bell or diaphragm side. If you don't hear your finger touching then rotate the chest piece till it clicks.
Grip the chest piece in between your middle and index fingers to give firm connection with the skin. To minimize external noises, avoid coming in contact with or rubbing the tubing or chest piece against clothes, bed covers or hair.
Simply position the diaphragm or bell directly above the portion of the system you wish to listen to, or auscultate.
When not being used it is better to store your stethoscope by allowing it to hang from the headset in order to avoid kinking the tubing.

The acoustic stethoscopes are the most common piece of medical equipment there is. So they are very important. The way they work is by amplifying then sending sound waves to the listeners ears.
They don't have a loud sound whenever you place the rim on your body part or someone elses. The acoustic scope was designed to emit a different level of sound as compared with the enhanced electronic ones. Keep in mind that these instruments have been in the medical market since the 20th century.
2) Electronic model stethoscope
The aftermath of advanced research and experiments, the electronic stethoscopes are the improved versions of the acoustic instruments. The advantage of these upgraded creations is the usefulness for the hearing challenged users.
Now even the faintest sounds can be heard easily. They are more costly than their non electric cousins, but the increased ability to hear body sounds more than makes up for the cost.
Knowing the differences in the two types of stethoscopes will help your buying experience. If you have hearing problems then definitely the electronic stethoscope is for you. The regular stethoscopes do just fine for the majority of nurses and doctors. As the price comes down you will see more people using the electronic models.
