Biomedical engineering, also known as “bioengineering”, is a branch of engineering that combines the design and problem solving techniques of engineering with biological and medical sciences to improve health-related and medical problems. Bioengineers have made many positive changes in many lives today. By designing live-saving objects such as artificial hearts, dialysis machines, and surgical lasers bioengineers have helped save many lives.
Biomedical engineers dates back to over 3000 years with the Egyptians. Egyptians created a wooden prosthesis to replace the big toe. Since then, bioengineering has developed a great deal. A big improvement this century has been the development of artificial lungs. When polio hit the states, many patients were put into a respirator made of two vacuum cleaners and an iron box. This invention, designed by Philip Drinker and Louis Agassiz Shaw, was nicknamed the “iron lung”. The iron lung pumped air into and out of the patient, allowing the patient to breathe. Iron lungs are replaced today with artificial lungs, which are more advanced and are p...
The Iron lung was one of the first medical advances made in the field of biomedical engineering (“Iron” par. 7). Philip Drinker, a professor at Harvard University, was the first person to invent an artificial respirator: the iron lung (Pendergast 119). Drinker was an American born who majored in chemical engineering (Schlager par. 2). He invented the iron lung in the year 1928 (Baughman 343). With the development of the iron lung, Philip Drinker established a way to save a patient’s life (Pendergast 119). He developed a machine that could work on anybody, no matter their body type (“Iron” par. 4). The iron lung, sometimes known as the Drinker tank, was invented to be used as an artificial respirator. This invention, however, was a means to keep patients with Poliomyelitis breathing, but it could not be used as a cure (“Poliomyelitis par. 7).
Stephanie Lee MS in Medical Device Innovation Personal Statement This past January, I had the most enriching opportunity to dissect and study the thoracic cavity of a human cadaver through the Advanced Cardiac Anatomy course held by the UMN. For the first time, I held a human heart within my hands, studied its anatomy, and was also able to closely examine the placement of a dual-chamber defibrillator. My company, Heraeus Medical Components, specializes in products for cardiac rhythm/heart failure management, so this was extra meaningful for me to not only see the leads, but also follow them to the sites of therapy within the heart. In a room of twenty-four cadavers, could I have somehow impacted any one of these patients’ lives?
The development of the artificial heart began in the early 1950’s. The initial prototype, developed in 1970’s by the artificial developmental staff at the University of Utah, allowed 50 hours of sustained life in a sheep. Although this was called a success, the implantation of the artificial heart left the sheep in a weakened state. It wasn’t until late 1970’s and the early 1980’s where the improvement of the artificial heart actually received attention as a possible alternative to a heart transplant. The remodeled product of the early 1970’s did more than just the 50 hours of sustained life; it enabled the cow to live longer and to live a relatively normal life, with the exception of a machine attached to the animal.
Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p. 430). During inhalation, the lungs expand with air, similar to filling a balloon. The pliable latex of the balloon allows it to expand, just as the pliability of lungs and their components allows for expansion. During exhalation, the volume of air decrease causing a deflation, similar to letting air out of the balloon. However, unlike a balloon, the paired lungs are not filled with empty spaces; the bronchi enter the lungs and subdivide progressively smaller into bronchioles, a network of conducting passageways leading to the alveoli (Marieb, 2006, p. 433). Alveoli are small air sacs in the respiratory zone. The respiratory zone also consists of bronchioles and alveolar ducts, and is responsible for the exchange of oxygen and carbon dioxide (Marieb, 2006, p. 433).
Polydactyly is the most commonly observed congenital digital anomaly of the hands and feet appearing in 1 in every 500 live births. The condition is characterized by an abnormal amount of digits per hand in which the extra digits may develop bilaterally, or it may occur on both or just one hand, foot, or some other combination. Usually the extra digits that develop are either small pieces of soft tissue or fully formed in appearance. It is noted that in around 80% to 90% of cases involve the peripheral digits, although it is possible that all digits may be affected. Depending on the location of the extra digit, polydactyly can be further classified into three types: pre-, post-, and central axial forms. Polydactyly can occur as an isolated disorder (non-syndromic) or alongside other symptoms or disease. Isolated polydactyly is typically caused by the inheritance of an autosomal dominant gene mutation, meaning the cause is not due to a multifactorial trait. However, most cases of polydactylism are linked to specific syndromes that cause congenital anomalies through a variety of gene mutations.

...iple treatments to regain their own ability to breathe. In building the device, the inventors examined other methods of treatment for people who were unable to breathe. The doctors discovered that manually attempting to force the patient into breathing did not provide enough air, but all mechanical methods until this point forced too much air in too quickly, causing damage to other important organs. One of the goals for the design was to be able to put almost any person in it successfully.
The one instant I can pinpoint as the genesis of my interest in biomedical science was the winter of sixth grade, when I picked up a book on creativity and the brain. I found it fascinating, but what really struck me was that here was a several hundred page book that mostly talked about how little we knew about its topic. It made me think. This was supposed to be a book about how much we’ve learned, and what it’s saying is that the progress we’ve made is only in finding out how little we know. This didn’t upset me; it made me curious. Because, of all the things that we should know about, surely our own minds and our own bodies are paramount among them, and yet we still have so much to learn. I’ve since learned that this phenomenon is not restricted to the biological – gravity is one of the most important things in our lives, yet we do not know its cause. But the biomedical questions continue to fascinate me, perhaps because the answers are so vital. Sure, cosmology is intriguing, but what about a cure for cancer, or even the common cold? What about a way of repairing or bypass...
My desire of studying biomedical sciences stems from my sciences interest, as it demonstrates a world not visible to the naked eye, plays a big role in everyday life. science specifically biology and chemistry are stimulating and challenging subjects , over the years of studying them ,my interest has increased because learning things about how our bodies function and how it relates to god’s creation is particularly interesting for me. I also find it very important because I’m Muslim. The biomedical science degree will open for me the door to learn more about the vast field of biology and its branches to a greater depth. I developed my knowledge in the science field by taking support classes in the lab at school; I was fascinated by how the body can function in different circumstances and the complexity of DNA, different organisms, chemical reactions, and also very importantly the mathematical aspect which gives me the chance to develop and use my logic and it inform me to new ways of looking at given problems.
Many great inventions have been made through research in biomedical engineering, for example, genetic engineering, cloning, and insulin. After insulin has been invented, there are still a lot of problems with the purity and the quantity of the insulin produced. Biomedical engineering devised a way to produce large quantities of insulin with a higher level of purity, which has saved a lot of human lives. Although biomedical engineering just been officially founded 200 years ago, its practice has been with us for centuries. According to The Whitaker Foundation website, 3,000-year-old mummy from Thebes, which uncovered by German archeologists, with a wooden prosthetic tied to its foot to serve as a big toe is the oldest known limb prosthesis and Egyptian listen to the internal of human anatomy using a hollow reed, which is what today’s stethoscope. No matter what the date, biomedical engineering has provided advances in medical technology to improve human health. These advances by biomedical engineering have created a significant impact to our lives. I have determined to become a biomedical engineer. Biomedical engineering will have a good prospect because it will become one of the most important careers in the future.
The reasons for the illness are not at the centre of the biomedical model. The biomedical model also receives the majority of government healthcare funding (over 90%). Furthermore, the biomedical model of health has been dominant for many years and played a large role in prolonging life expectancy, bio-living or living organisms and also played a role in medical science of diagnosing and treating disease. It is a community approach to prevent diseases and illnesses.

The changes it could bring are amazing, there is really no reason to stop learning more about helping to heal the human body. Works Cited Work Citations The "Genetic Engineering" 123HelpMe.com. 08 May 2017 http://www.123HelpMe.com/view.asp?id=67046>. King James Version. Arizona:
Biomechanical engineering is driven by needs similar to those of biomedical engineering. There is always a constant need to improve medical equipment while keeping it cost efficient. These are the two main needs for all biomedical engineers. Biomechanical engineering is specifically dedicated to applying the scientific of knowledge mechanical systems and engineering to biology and the human body. One of the many needs that drives this biomedical subfield is society’s need for more advanced equipment and machinery. Some recent advances show this need. In the last decade, biomechanical engineers have invented and innovated new robots and machines that can assist a surgeon in surgery or serve as an artificial liver. These machines satisfy the need to improve and innovate new equipment that can save lives and improve how people in the medical field perform their
Genetic Engineering may or may not be beneficial. In terms of being an advantage, it can help decrease the death rate by destroying disease and has the potential to increase the lifetime of humans. Based on what scientists have discovered , genetic engineering is used as a beneficial technique to slow down the aging process of people, meaning it helps to store more life existence. Cloning is one of its biggest successful advantages which developed a whole new discovery in today’s life making life more interesting and easier. This cloning process has made it pos...
