Visual Prosthesis: Selling a Dream to Visually Impaired (A literature review of advancements in the field of Visual Prosthesis) Abstract Visual prosthesis is by far the best bet to restore vision in a patient suffering with visual loss. This paper provides a literature review of the various technological advancements made over time and how these advancements have proved noteworthy in fields of visual prosthesis. To develop a basic understanding about the visual prosthesis, the anatomy and…

Researching for life’s improvements is the goal for every engineer, this explains the countless hours engineers spend inside an office or a laboratory. Although people think of engineers as only creators of lifeless technology, many of biomedical engineers specialized in technology for the living. Meeting between medicine and engineering, biomedical engineers find solutions for medicine and, in some cases, people’s disabilities. These disabilities appear from accidents in the workplace to war…

lifetime of use. Some items that are necessary before you begin the process of cleaning your trumpet are a bathtub or bin large enough to submerge your trumpet, lukewarm water, and dish soap. You will also need a trumpet pipe snake, valve brush, mouthpiece brush, valve oil, and slide grease. Once you have all of these items you can begin cleaning. Begin by taking each slide out of the trumpet carefully. A slide is the pipes that can be pulled in and out of the trumpet to tune or in this clean…

A stenotic valve is a valve that has been narrowed due to excessive calcium. This can cause chest pain, chest tightness, heart palpitations, fatigue and shortness of breath.4 There are generally two types of valvuloplasty: Aortic valvuloplasty, and mitral valvuloplasty.4 These two procedures differ based on the type of valve that is being widened. For example, aortic valvuloplasty treats the narrowing of the aortic valve, or in other words the valve that is located between the left…

Check the cylinder valves to see if they are tightly closed and see if the gauges read zero on the cylinders. Check the…

They are both comprised of cardiac muscles which contract involuntarily to pump blood. Each side of the heart contains valves which prevent the regurgitation of blood. The left and right side of the heart have a mutual muscular segment by which they are separated and is known as the atrioventricular septum. Differences between Left and Right Side of the Heart? • Left side…

How to change a cartridge Shower Delta ? The valve cartridge in the Delta Faucet regulates the temperature and controls the flow of water coming into the faucet through a line of hot and cold water. Water temperatures inconsistent, a leaky faucet and the loss of water flow to the shower, all the problems are caused by a cartridge valve for damage and wear. The shower handle is fixed to the front end of the valve cartridge. To remove the valve cartridge, the handle and the rest of the tap is…

This failure is due to the progressive thickening and lengthening of the leaflets that compose the mitral valve causing them to bulge (prolapse) upward into the left atrium. This prolapse can allow blood to backflow into the atrium (regurgitation). MVP is most commonly caused by abnormally stretchy valve leaflets and will affect approximately 2% of the general population. Individuals with MVP are often asymptomatic but can sometimes face life-threatening…

is the stage where ventricles begin contracting, the aortic and semilunar valves close which prevents a change in volume. The fourth stage, ventricular ejection, is the moment where the ventricles are emptying themselves through contractions. The final stage is called the isovolumic relaxation time, during this stage pressure decreases, no blood enters the ventricles, the ventricles then begin relaxing and the semilunar valves close due to pressure of blood found in the aorta. The heart also…

the left atrium and left ventricle are not working properly due to mitral valve not working appropriately. The reason this set of valves was chosen is because in the passage, it stated that the X-Ray show an enlargement in the left atrium and left ventricle. This happen is due to inefficient cycle of blood resulting in abnormal heart sound or heart murmur. Mitral valve of the left side is misshape and less flexible. Mitral valve has a leakage and allows blood to backflow into the atrium when…
