When you hear of a great invention that changed the world today you may wonder who the genius that created it is. Well one invention that drew my attention was the Stethoscope. The Stethoscope was invented in 1816 by a French man named Rene Laennec.
Laennec came up the idea while examining an overweight female patient. Laennec felt that using his ear to examine the patient was not only inappropriate but that it would be less accurate. Laennec was embarrassed to place his ear to her chest, which was the method of auscultation used by physicians at the time. Laennec remembered that sound travels through solids, so he rolled up twenty four sheets of paper, placed one end to his ear and the other end to the woman’s chest. He was delighted to discover

If you go to a doctor’s office or hospital you will always see nurses and doctors suited with a Stethoscope. These devices make it easier for doctors to hear what is happening with our hearts, lungs, and chests. Some of the things doctors are looking for are irregular heartbeats, wheezing in the chest, and congestion in the lungs. Today’s version of the Stethoscope still resembles the old model but is an electronic version and no longer acoustic. You may be asking yourself what the difference is; well there are many different versions of Stethoscopes today and they vary in design and material. The devices are made with a Y-shaped rubber tube that allows sounds to enter the device at one end and travel up the tubes and through the ear pieces. Other Stethoscopes have a two sided sound detecting device that listeners can reverse, depending on whether or not they need to hear high or low frequencies. Stethoscopes are also used in conjunction with a device to measure blood pressure. Stethoscopes can be used by a variety of experts to examine an assortment of things in our bodies. Although there are many different versions of the Stethoscope they all started with the original invention by
He had produced an unknown ray being emitted from the tube that could pass through the paper. He found that this new ray would pass through most objects, casting shadows of solid substances. He first investigated with his hand and was surprised when he saw his bones. His discovery would open up an exciting field for doctors because now it was possible to stu...

Lee De Forest also had a role in the invention of the hearing aid because he invented the vacuum tube, he applied the 3-element tube, he invented it in the year 1907 in the Western Electric Company in New York City. And that was when he started producing the superior hearing aids in the year 1920. The hearing aids he invented amplified 70 decibels(dB) and they also had a higher response.The only bad thing about it was that it wasn’t portable. A couple years later Western Electric came up with a new model: this new model fit in a in a small wooden box which weighed 4 kg which was a more portable
Ultrasound is one of the most vital inventions in women health care. The advancement of wave technology throughout history formed the basis for the ultrasound. Ultrasound history is embedded in innovations on wave technology (Woo, 2015). Earlier designs of ultrasonic devices were not in the field of medicine until in the 1950s (Woo, 2015). Even then, the devices were employed for therapy before they were improved and used for diagnosis.
Banneker invented his first clock in 1753. It was made out of American Parts. People travel al across the world to see his wonderful invention. It was made from hand carved parts. And the clock struck for over 50 years. Unfortunately Banneker died on October 9th, 1806. His mother and his father by
In 1877, Edison created his favorite invention of all; the phonograph. Edison actually created this by accident while trying to make a telephone, but after he finally perfected it, everyone wanted to know about how it worked. It became popular so quickly, that he was even invited to the White House to show off his new and unusual machine that mimicked sounds
Mitral Valve Stenosis is a quiet disease that does not always reveal itself until later stages of the disease process. Symptoms that may present are shortness of breath, fatigue with activity, and progress to more severe symptoms such as swollen extremities and coughing up blood in later stages of the disease. Less common symptoms that can be seen are chest pain, trouble swallowing, throat hoarseness, and skin color changes. During auscultation examination a decrescendo murmur, also known as a diastolic rumble, can be heard during diastole at the apical listening region. An opening snap can be heard after S2; S1 will be loud and distinct, with an accentuation of the murmur beforehand. Testing done to diagnose Mitral valve stenosis include
The innocent cardiac murmur is still the most common finding in healthy children and usually be diagnosed through obtaining a complete history and performing a complete physical examination; cardiac murmur may be the first sign of a structural cardiac disease and should not be ignored; referral to a cardiologist for further evaluation when murmur assessment is not clear and diagnostic uncertainty is present (Etoom & Savithiri, 2013). Heart murmurs are abnormal sounds that are auscultated via stethoscope. When a heart murmur is detected, it is important to note the location, the pitch, is it affected by anything, such as position change, the loudness, when it occurs, and how long it lasts. All of those things will assist in diagnosing the murmur.
Assessing the heart through a physical examination or using medical technology to detect the heart’s current state of health has never been this easy since the history of trial and error of figuring out this complex organ. Depending on the condition of the individual, examining the heart can vary from a simple session of questions, regarding the person’s lifestyle and activities, to using medical equipment to the heart’s sounds for any murmurs, pulse rate, blood pressure, and etc. A few of the possibly many more other ways the doctor is able to assess the patient is by physically touching and pressing on certain areas of the body in order to feel for any abnormalities, taking the individual’s blood pressure using what is called a sphygmomanometer, taking one’s pulse rate in any one of the vital signs, and listening to the heart using a stethoscope. These assessments help with further diagnosing any sort of issue relating to the heart in order to begin the treatment process. For example, taking one’s blood pressure shows whether the individual has a low, normal, or high blood pressure (hypotension for severely low bp, hypertension for severely high). Another example is the physical assessment for Coronary Artery Disease. Coronary Artery Disease is categorized by two types: atherosclerosis, meaning the buildup of plaque, fats, or cholesterol, and
Cardiac sonographers also known as echocardiographers are medical professionals who use a type of imaging called ultrasound that uses high frequency sound waves to create images of the heart, look at the functioning of the hearts chambers, vessels, walls, blood flow, and valve function( “Cardiac Sonography: Job,” 2013). Cardiac sonographers work with ultrasound equipment and a transducer probe to generate sound waves into images. They use sonography to produce visual images that can assist in the treatment or diagnosis of certain heart and blood vessel conditions. They must be skilled in recognizing and pointing out any abnormalities. Therefore, they must be familiar with basic cardiac conditions. However, cardiac sonographers do not diagnose the patients themselves, but they do work alongside many cardiologists and physicians who determines the issue if one is present ( “Cardiac Sonography: Job,” 2013). Cardiac sonographers mainly perform the technical aspects of the examinations, assess the findings, and report them to the cardiologist for further review. Preforming echocardiograms is not the only job a sonographer has, they provide a big portion of patient care throughout their day by reviewing patients medical records, prepping them for the echo, and instructing them during the
Many inventors have left their mark on society. One inventor, in particular, is commonly found at the top of the list of the greatest inventors in world history. He has influenced and impacted many facets of our lives. His inventions laid the foundation of many industries and products which still exist today.
An artificial heart is a mechanical device, about the size of an orange, which is connected to your heart or implanted in your chest to help or replace a weakening heart. It may have several valves, a mechanism to propel blood forward, and one or more chambers. Sometimes an artificial heart may help your heart temporarily, until yours recovers. If this is the case, the artificial heart will be removed when it is no longer needed. More commonly, when there is irreversible heart muscle damage and your heart can t recover, the artificial heart stays until you can have a heart transplant. If no other options are available, an artificial heart may completely and permanently replace your heart. There are two types of artificial heart. An artificial
In proposing that he was the first inventor, Leibniz states that "it is most useful that the true origins of memorable inventions be known, especially of those that were conceive not by accident but by an effort of meditation. The use of this is not merely that history may give everyone his due and others be spurred by the expectation of similar praise, but also that the art of discovery may be promoted and its method become known through brilliant examples.”
The hand clock (watch) was invented by A French Company named Berege back at 1810. During the 1800's a drastic advancement has occurred in mechanical clocks with the invention of the naval time keeper which is used up till today by sailors to find their position in an area.
Because of this, France is one of the most innovative and marvelous countries to live in. The stethoscope is a very useful tool for doctors now in the 21st century. Even with the colossal improvements In 1816 a French physician Rene Laennec, created the first stethoscope.
