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

that the sounds were not only conveyed through the paper cone, but they were also loud and clear. Imagine what our lives would be like without some of the great inventions in our healthcare field, which we have today. Laennec actually didn’t name the Stethoscope because he didn’t believe in naming such a thing. However he was tired of what others were calling his invention, so he then decided to name it the Stethoscope. Although Laennec actually stumbled across a way to listen to patient’s heart, lungs, and chest, with only paper, the first version of the Stethoscope was actually replaced by a hollow wooden tube. This first version of the Stethoscope was made of three parts that fit together with a wooden screw, tread and brass tube fitting. Each end of the Stethoscope was hollow. Overall the first version was 12.6 inches long. A second version of the Stethoscope was also made of wood but a much stronger cedar wood and had three parts. The three parts for his second version were, a rounded wood pressure fitting, a brass tube fitting, and horn rings to hold the other pieces in place. There was also a third version of the Stethoscope which was developed in England. In this third version of the Stethoscope there was no brass fitting used to hold the chest plug. Instead the parts are attached by a funnel shaped wood pressure fitting. It took Laennec several attempts to get from the rolled up pieces of paper to these other versions of the Stethoscope. Laennec’s invention of the Stethoscope was not embraced immediately but was eventually recognized by physicians as a valuable instrument for physical diagnosis. In the early 1850’s a rush for a new model of Stethoscope was placed. Physicians wanted a Stethoscope they could use for either left or right ear. Arthur Leard presented a double Stethoscope at the great exhibition in London in 1851. Then in 1852 Dr. George Cammann of New York produced the first usable binaural Stethoscope and is the same style of Stethoscope we see used today. Today doctors and nurses still use Stethoscopes to examine patients.
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
Laennec. Nowadays we are living in a very technologically advanced world and our hospitals and doctors office are equipped with machines that have been re-evaluated and enhanced over the years. These enhancements’ make everyone’s lives better and help physicians to give better, more antiquate diagnosis. The future of the Stethoscope is looking grime due to the advancement of technology. Today we have so many machines that can tell doctors exactly what’s wrong with us, with just the push of a button. An example of this is someone who goes to the doctor and is having breathing problems they use an x-ray to examine the patient’s lungs and don’t rely on the Stethoscope alone. In the generation of technology many doctors have abandoned the use of their Stethoscopes and rely solely on other machines. This futuristic style of medicine is pushing the old-fashioned healing out the door. One thing that doesn’t appeal to most doctors, who are still using their Stethoscopes today, is that new machines are taking away the doctor to patient relationship. Sometimes healing comes from knowing that the doctors care for you and they show this with their hands on approach, by using a Stethoscope. In conclusion, the invention of the Stethoscope is one of the best and most long lasting inventions we have today. All thanks are given to the Stethoscope because this small but mighty invention can let medical experts with just a sound of a heartbeat, or wheezes of a chest determine what is wrong in our bodies solely from the outside. The medical field today might have been different and more difficult without the invention of the Stethoscope.
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

The cylinder phonograph proved to be successful, but the problem with the machine was that the tin foil only allowed a few uses. With the help of another great inventor, new advances could be made to improve this invention. The inventor of the telephone, Alexander Graham Bell, had set up a laboratory for his cousin, Chichester Bell and Charles Tainter. Bell a...
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
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.
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.
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
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.
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
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
The most important and influential discovery was the practice of surgery. With this invention, human life became more sophisticated, humans lived longer, and we obtained a knowledge of ourselves sufficient enough to break the boundaries built by ignorance. Lacking prescription drugs, accurate tools, computer technology, and any background experience to build from, our ancestors struggled to learn how to repair the human body. They did an suprisingly competent job of treating the sick and injured. Some of the medical technology developed in ancient times surpassed anything available in the modern world until the 18th century or 19th century. In eras wherein religious views took precedence over medicine and logic, surgical advancement was difficult. The knowledge we have now was obtained from these people's exploits.
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
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.
