This subsequently led to the invention of the CT scanner. Its commercial version was invented by Dr. Godfrey Hounsfield who received a Nobel Prize for medicine in 1979. This device was able to display multiple layers within multiple X-ray images.]]> 2021-05-21 06:23:40 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546825132 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546829278 French physician René Laënnec invented the 'stethoscope,' creating a trumpet-shaped wooden tube that amplified sounds coming from lungs and heart.

Today this Salvarsan is known as Arsphenamine. It was the first drug to effectively counter Syphilis, marking the beginning of anti-bacterial treatment. Antibiotics have revolutionized medicine, and in combination with vaccines have helped with eradicating diseases like tuberculosis.]]> 2021-05-21 06:26:50 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546830720 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546834658 Beginning with an attempt by Edward Jenner in 1796 to use inoculations to tame the infamous smallpox virus, the usefulness and popularity of vaccines grew very quickly. Throughout the 1800s and early 1900s, various vaccinations were created to combat some of the world’s deadliest diseases, including smallpox, rabies, tuberculosis, and cholera. Today, vaccines continue to save millions of lives each year - including jabs that protect against deadly flu strains and can help prevent some cancers.]]> 2021-05-21 06:29:07 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546834658 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546838350 Before the first use of a general anaesthetic in the mid-19^th century, surgery was undertaken only as a last resort, with several patients opting for death rather than enduring the excruciating ordeal. William T. G. Morton made history in 1846 when he successfully used ether as an anaesthetic during surgery. Over the 150 years since, safer anaesthetics have been developed, allowing millions of life-saving, painless operations to take place.]]> 2021-05-21 06:31:13 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546838350 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546843718 French microbiologist Louis Pasteur proved through a simple experiment that infectious disease was a result of an invasion of specific microscopic organisms - also known as pathogens - into living hosts. This new understanding marked a significant turning point in how diseases were treated, controlled and prevented, helping to prevent devastating epidemics that were responsible for thousands of deaths every year, such as the plague, dysentery and typhoid fever.  ]]> 2021-05-21 06:34:06 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546843718 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546844722 A hypodermic needle with its austere appearance and a simple working principle was invented only about 150 years ago. Before that in ancient Greece and Rome, physicians used thin hollow tools to inject fluids into the body. Today, these needles are used to deliver correct drug dosage in treatment and extract body fluids with minimal pain and risk of contamination.]]> 2021-05-21 06:34:41 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546844722 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546848244 Defibrillation of the heart isn’t a very recent concept, it has been known for decades, but its introduction into clinical setting was brought about by Claude Beck when he successfully defibrillated a young boy’s heart during surgery.

The artificial heart has evolved over the decades saving countless lives. ]]> 2021-05-21 06:37:56 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546851020 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546852016 Modern disposable catheters were invented in the 1940s by David S. Sheridan, a man who is also known as the Catheter King. Disposable catheters give these people the opportunity to live lives relatively normal lives through the process of intermittent self-catheterization.  ]]> 2021-05-21 06:38:29 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546852016 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546854687 In December 1954, the first successful kidney transplant was carried out by Dr. Joseph Murray and Dr. David Hume in Boston, USA. Despite many previous attempts in history, this was the first instance where the recipient of an organ transplant survived the operation. The turning point came when various technical issues were overcome, such as vascular anastomosis (the connection between two blood vessels), placement of the kidney and immune response. In 1963, the first lung transplant was carried out, followed by a pancreas/kidney in 1966, and liver and heart in 1967. Aside from saving thousands of lives in the years following, transplant procedures have also become increasingly innovative and complex, with doctors successfully completing the first hand transplant in 1998 and full-face transplant in 2010!]]> 2021-05-21 06:39:45 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546854687 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546857764 The incredible potential of stem cells was discovered in the late 1970s, when they were found inside human cord blood. Two specific characteristics make stem cells remarkable: they are unspecialised cells that can renew themselves through cell division even after being inactive, and under certain conditions can be used to make any type of human cell. This discovery has enormous potential and stem cell therapy has already been used to treat leukaemia and other blood disorders, as well as in bone marrow transplantation. ]]> 2021-05-21 06:41:23 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546857764 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546864898 Aspirin is a common drug for relieving minor aches, pains, and fevers.

This was one of the pivotal moments in medical science that would ultimately lead to cleaner operating theatres and higher survival rates of patients. He was convinced, correctly as it turned out, that cleanliness during surgery was vitally important to the efficacy of the procedure and subsequent recovery of the patient.]]> 2021-05-21 06:48:15 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546872215 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546878114 In the early 1950s, American biologist James Watson and British physicist Francis Crick came up with their famous model of the DNA double helix. Franklin was an expert in a powerful technique for determining the structure of molecules, known as X-ray crystallography. When the crystallized form of a molecule such as DNA is exposed to X-rays, some of the rays are deflected by the atoms in the crystal, forming a diffraction pattern that gives clues about the molecule's structure.]]> 2021-05-21 06:51:13 UTC https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546878114 chinnxii https://padlet.com/chinnxii/medicalinventionsanddiscoveries/wish/1546887602 An electrocardiogram is a simple, painless test that measures your heart's electrical activity.
