History of stethoscope


Hii friends… Today I am going to inform you about the (journey) History of stethoscope. Let me explain some parts of the stethoscope.


It all commenced with a paper tube.Modern stethoscopes: 200 years in the making.

In 1816, French health practitioner Rene Laennec invented the first stethoscope .he use of a long, rolled paper tube to funnel the sound from the patient’s chest to his ear. Accounts fluctuate on precisely how Laennec created his invention, however it used to be clear from the establishing that the acoustic homes of the tube radically increased Laennec’s capacity to hear quintessential coronary heart and lung sounds. Laennec coined the title “stethoscope” from two Greek words: stethos (chest) and skopein (to view or see). He additionally referred to as his approach of the use of the stethoscope “auscultation” from “auscultare” (listen).

4. • The chest piece.
It consists of bell and diaphragm that are rotated into position. The diaphragm or bell must be in proper position during listening of the heart sounds through the stethoscope. The diaphragm is the circular, flat portion of the chest piece covered with a thin plastic disk. It transmits high pitched sounds created by high velocity movement of air and blood. Bowel, lung and heart sounds are auscultated using the diaphragm. The bell of the chest piece is usually surrounded by a rubber ring. The ring avoids chilling the client, with cold metal when placed on the chest. The bell transmits low pitched sounds cre- ated by the low velocity movement of blood. The car piece should be removed regularly and cleaned of cerumen (car wax) with spirit swab. The bell and diaphragm are cleaned of dust and body oils. Clean the tubing with mild soap and water or alcohol swabs.

When did doctors start using stethoscopes?

Facts of stethoscope:-

And now , we know the history of stethoscope.The stethoscope can be used to listen to a variety of sounds to assist with the assessment and diagnosis of a patient.  These include lung, heart and bowel sounds.  The stethoscope is also routinely used in association with a sphygmomanometer to assess blood pressure by listening to blood flow sounds.

When using a stethoscope remember that the ear tips should point forwards in your ears to follow the natural path of your ear canals to ensure best acoustics.  Best practice when using a stethoscope is to use it at skin level and don’t forget to clean it after use to help control the risk of infection.

Confidence is actually a skill that you can develop-even if you can’t imagine how that could be possible for you right now…Boost your self confidence?


Negativity is your number one enemy. It’s the first thing you need to learn to deal with. You must stamp it out. I cannot stress this enough. Being Positive is an essential element
of self-confidence.



Lacking confidence often means having a very low opinion of yourself. There’s only one answer to this (and there’s no getting out of ft if you want to move forward) .you’ll need to learn to have self-love.


Good communication skills really are an essential step in learning how to gain confidence. These skills are a delicate balance between listening and speaking.



Knowing how you come across to people really matters. Most people get this wrong. They
assume they look and sound terrible, embarrassing even.Reconciling this is essential.


You must do the things that challenge you most. It’s impossible to get more confident if you just think about it. It takes courage to step out of your comfort zone. t is the right thing to do.



If you fail at something, try it again but approach it differently. Never avoid situations that you have failed at if they matter to you. Learn the mistakes and move on. This takes resilience.

Think of things you’re good at

Everyone has strengths and talents. What are yours? Recognising what you’re good at, and trying to build on those things, will help you to build confidence in your own abilities.


Set some goals

Set some goals and set out the steps you need to take to achieve them. They don’t have to be big goals; they can even be things like baking a cake or planning a night out with friends. Just aim for some small achievements that you can tick off a list to help you gain confidence in your ability to get stuff done.


Talk yourself up

You’re never going to feel confident if you have negative commentary running through your mind telling you that you’re no good. Think about your self talk and how that might be affecting your self-confidence. Treat yourself like you would your best friend and cheer yourself on.


Get a hobby

Stop Comparing Yourself to Others and boost your self confidence.Try to find something that you’re really passionate about. It could be photography, sport, knitting or anything else! When you’ve worked out your passion, commit yourself to giving it a go. Chances are, if you’re interested or passionate about a certain activity, you’re more likely to be motivated and you’ll build skills more quickly.



Too many very capable people lack faith in their own abilities. This stops them doing the things they really want to do. The main reason for this? A fear of failure. The thought of getting it wrong is enough to stop them doing it. Exercise boost your self-confidence.
