Biomedical engineering is a highly interdisciplinary branch of engineering that

applies electrical, mechanical, chemical, optical and other engineering principles to

understanding, modifying, and controlling biological (both human and animal) systems

as well as to the design and manufacture of products that monitor physiological functions

and assist in the diagnosis and treatment of patients.

The field is quite broad, encompassing biomechanics; biomaterials; biomedical

instrumentation (such as biosensors); medical imaging; biotechnology (the creation or

modification of biological material for beneficial uses, such as tissue engineering);

prosthetic devices and artificial organs; and rehabilitation engineering (the design and

development of therapeutic and rehabilitation devices and procedures).

 

It is a new kind of engineering and therefore graduates with a degree in biomedical engineering are well sought after with a variety of career options open to them. Biomedical engineering teaches you the engineering processes in sensitive bodies, as opposed to other engineering degrees. This enables you to apply your knowledge of sensitive systems into many fields of engineering, enabling you to be the best kind of engineer. Currently, not only is medicine making advances, but so is machinery, and this occupation allows the combination of the two to help further medical achievements, and create treatments, artificial limbs, and artificial organs etc.

 

The biomedical engineering program (B M E) is interdisciplinary in scope. The participating faculty are from the Colleges of Engineering, Veterinary Medicine, Education and Agriculture. Biomedical engineers are concerned with the application of engineering concepts and analytical techniques to biological and medical problems. They are interested in developing new concepts, instrumentation, and materials for use with living systems. In addition, they seek to understand those phenomena of living systems which have functional capabilities desirable in the design of physical systems. Graduates of the program are able to understand scientific literature, formulate hypotheses, complete independent research or design projects and report their results. They engage in research or design careers in the various fields of biomedical engineering.A biomedical engineer is a must in a hospital. No hospital can perform without having a biomedical department, particularly hospitals which are into tertiary and secondary care. We have to look at a biomedical engineer as a resource which is on line with the management resource of an organisation and not as an engineer. Lot of hospitals use biomedical engineer as if he is just a component of engineering services of a hospital. He is a very intelligent resource which looks after the most expensive part of the hospital and so we need to use the resource adequately. He not only takes care of your equipment but forms an integral part of the hospital’s management team. He also needs to constantly keep abreast of the new technologies that are happening. An institution head should look at a biomedical engineer as a guide.Biomedical engineering is a trendsetter in establishing a symbiotic relationship between engineering, medicine, biology, and physics. The main objective of the subject is to bring about an improvement in the overall quality of healthcare. Biomedical engineers can derive creative satisfaction by designing prosthetics, synthetic blood vessels, automated patient monitoring systems, blood chemistry sensors, ultrasound, and artificial intelligence for clinical decisions. State-of-the-art infrastructure helps engineers to delve profoundly into the highly regulated feedback mechanism at the genetic level and render humanitarian research activities.

 

It includes Electromedical Engineering, which includes bioelectric signal processing (EEG, EMG, ECG and such), imaging (such as CT Scan, Ultra sound scan, MRI, PET, X ray), interventional imaging like various forms of endoscopy, patient monitors, bioanalytical instrumentation like autoanalyzers, design and manufacture of biomedical disposables like syringes giving and taking sets. dialysis and blood collection and processing systems, artificial internal organs like heart valves, left ventricle assist devices, orthopedic and dental implants and a lot more besides.It is a multidisciplinary field, which can accommodate clinicians, engineers of various specialties, biochemists, microbiologists, toxicologists, veterinarians as well as bio technologists.It combines the design and problem solving skills of engineering with medical and biological sciences to help improve patient health care and the quality of life of individuals.

 

Biomedical engineering is advancing rapidly and producing important innovations that improve our quality of life. From understanding the human genome to pioneering surgical tools, biomedical engineers are committed the advancement of research and education in biotechnology, biomolecular engineering, sensory systems, cardiopulmonary engineering, neuroscience, micro-and nano-systems and biomechanics and biomaterials.Biomedical engineering integrates physical, chemical, mathematical, and computational sciences and engineering principles to study biology, medicine, behavior, and health. It advances fundamental concepts; creates knowledge from the molecular to the organ systems level; and develops innovative biologics, materials, processes, implants, devices and informatics approaches for the prevention, diagnosis, and treatment of disease, for patient rehabilitation, and for improving health.

 

Ventura Eye Institute asked:




LASIK is an acronym for laser-assisted in-situ keratomileusis which is an eye surgery. Lasik surgery is the most well-liked method for correcting visualization difficulties caused by refractive error, in which the eyes fail to focus light appropriately. Lasik surgery treats nearsightedness, farsightedness, and astigmatism, radically decreasing and often abolishing the requirement of glasses or contact lenses.

This is the following process of Lasik surgery:

Initialy, the eye is anesthetized with use of limited anesthetic drops. Once you can’t sense your eye, a small flap is formed on the surface of the cornea by means of a particular instrument known as a microkeratome which allows the surgeon to access the corneal bed.

After cautious placement of the corneal flap, a cool-beam, excimer laser restructures the cornea, shifting the eye’s focal point to endow with clearer vision.

The corneal flap is then softly relocated and will begin to cure instantaneously.

In conventional Lasik surgery reforms the cornea, the part of the eye that visualizes light on the retina. In Lasik surgery, that reshaping ensues after a planned laser treatment taking into account the precise refractive error of the eye. A nearsightedness disease is corrected by flattening the cornea, while farsightedness is fixed by steepening the cornea. The concluding result of lasik eye surgery is for most patients, vision good enough that they no longer need glasses or contacts for most activities.

But in customized lasik surgery, physicians apply it to patients to reduce night vision turbulences like glare and halos. A good percentage of custom Lasik surgery recipients gain twenty by twenty visions from this method, which uses modified treatment in the form of the wavefront analyzer, which permits for a higher level of diagnostic information.

Wavefront technology begins through NASA, where it was initially used for high-powered telescopes. The wavefront analyzer generates a detailed map of your visual system twenty-five times more precise than standard lasik surgery can produce. This level of fact allows for tiny irregularities known as higher order aberrations to be incarcerated and fixed. This highly customized data which is then transferred to the laser used in your Custom lasik surgery treatment, where it will best treated for your sole vision problems.

Lasik surgery can fix up the vision of the nearsighted, the farsighted, and those with astigmatism. Once you have had your lasik surgery, you will possibly want to recommence your normal activities almost instantly, but be cautious. Whilst in lasik surgery, you should still pursue this rough timeline before you jump back into your normal activities.

Philip Cordova asked:




My practice is in an area that is filled with people that sit at their computer all day. They don’t have the best posture in the world, and they don’t always have the best ergonomic set up for their desks. They are also under a lot of stress. However, usually bad posture, stress, and poor ergonomics will lead to frequent headaches, neck and upper back pain… not low back pain.

Low back pain is usually reserved for those employees doing physical work, a lot of lifting, bending, and stooping. During the times that I’ve seen patients with more physical jobs, most of them presented to my office with low back pain. Now, the top half of their body provides the more abundant symptom.

So if you don’t do physical work all day, why are you getting low back pain? I noticed the same two major muscle groups being tight and stressed over and over again. By stretching these two major areas, a lot of very common symptoms, including low back pain and sciatica seemed to get quick relief. Doing the stretches also seemed to make a difference long term in my patients’ ability to get longer lasting results from their chiropractic care.

The first muscles you should stretch are your hamstrings. You sit all day and the seated position puts them in their shortest position. Standing up means your hamstrings are pulling on your pelvis and pulling things out of place. Keeping this muscle more flexible is key in helping your back pain.

People have the most trouble because they can’t quite get it stretched. First step would be to get off the floor. That’s usually too much! Stand up or sit in a chair and put your leg straight out on a chair. Slowly try to touch your toes. Just go slow and only as far as you can reasonably go without pain. Hold the stretch for at least thirty seconds. Repeat on each side twice. Usually people just don’t hold their stretches long enough to do much good. Consistency will make the difference in getting more flexible.

The next muscles to stretch are your hip rotators. Relieving the muscles here takes a lot of strain off the sciatica problem. For this one, you can even do it while lying in bed or on the floor. Keep one leg straight while you pull your other leg up to your chest. You should feel a pull. You can further stretch this area by pulling your knee across your body to get better results. Again, hold the stretch for at least thirty seconds.

Chances are, you’re not going to stop working on your computer any time soon. Taking a few minutes each day to do some stretching will make a world of difference. Seeing a chiropractor on a regular basis is also a huge help.
