About Me

There are medical devices that people are so familiar with that they often take them lightly. Let's take a look at the great strides and breakthroughs that have saved millions of lives throughout history.

Science is constantly evolving, and it can be said that medicine is one of the most progressive fields. Over the years, medical breakthroughs have offered an alternative to a tedious, tedious process or found solutions to seemingly intractable problems. Let's take a look at the medical inventions that have revolutionized the history of world medicine.

1. Thermometer

The thermometer is an extremely popular medical device today, but it is still unclear who came up with this great idea. Although Galileo invented the thermometer in the late 1500s, Gabriel Fahrenheit's first mercury thermometer in 1714 is the achievement that has been used to date. Thermometers are made based on the principle of thermal expansion of substances. However, at present, electronic thermometers are being preferred over mercury thermometers because of the safety and convenience of this product.

2. Stethoscope

In the past, when there was no stethoscope, doctors often had to put their ears to the chest to listen to the patient's heartbeat. This is obviously a rudimentary and ineffective measure because if the patient has a thick layer of fat, the results will have a very significant error. French doctor René Laënnec encountered such an unfortunate case when he had difficulty assessing the heart rate accurately for a patient with an oversized body. Thus, he invented a 'stethoscope' shaped like a wooden trumpet to amplify the sounds emitted by the lungs and heart. That principle is still maintained today, with more advanced stethoscope devices.

3. X-rays

It is difficult to accurately diagnose and treat common injuries such as fractures and dislocations without X-ray imaging technology. However, this method was a fortuitous discovery of the German physicist Wilhelm Conrad Röntgen. He was checking to see if cathode rays (cathode rays) could pass through glass when he suddenly noticed a light coming from a nearby chemically coated plate. He called these light-producing rays X-rays, because of their unknown nature. This discovery won the Nobel Prize in Physics in 1901.

4. Antibiotics

When it comes to antibiotics, we usually refer to Alexander Fleming's Penicillin in 1928. In fact, Salvarsan was the first synthetic antibacterial drug made by Alfred Bertheim and Paul Ehrlich to treat syphilis and resistance. bacteria in 1907. Salvarsan was used to treat syphilis during the first half of the 20th century and is now known as Arsphenamine. In this day and age, antibiotics and vaccines have helped treat countless diseases such as tuberculosis, rabies, or Japanese encephalitis.

5. Needles

Before the advent of the compact needle, doctors used rudimentary hollow instruments and even goose-feathers for intravenous injection. It wasn't until the 1800s that Alexander Wood and Charles Pravaz invented the modern hypodermic needle and syringe, respectively. These needles help deliver the correct dose of medication in the treatment, causing less pain to the patient and reducing the risk of infection.

6. Eyeglasses

There is no specific information about who invented this small but global product. Just know that many centuries ago, scholars and monks used to use a form of eyeglasses with the frames placed in front of the eyes and balanced in front of the nose (no pins placed on the ears) to see. By 1800, when the publishing industry developed and the number of people with nearsightedness also increased, eyeglasses had become a commercially available product.

7. Pacemaker

This important invention was the work of two Australian scientists, Mark C. Lidwill and physicist Edgar H. Booth in 1926. Their prototype was a handheld device consisting of two poles with one pole connected. with a piece of prosthetic skin in a saline solution and the other pole connected to a needle inserted into the patient's heart chamber. Although the structure is somewhat rudimentary, the invention of both has successfully restored the life of a baby that was almost stillborn. To this day, pacemakers have become more sophisticated with an average battery life of up to 20 years.
