Biomedical Inventions

Biomedical Inventions

Many of the biomedical inventions were created by biomedical engineers. One example was the insulin. Leslie Geddes, a professor emeritus at Purdue University, is an electrical engineer and inventor who has taught over two thousand biomedical engineers. He received the 2006 National Medal of Technology from President Bush for his contributions to the field. He also invented the miniature defibrillator. In addition, he contributed to the development of burn treatments and insulin. Some of his other co-discoverers include John Macleod of Case Western Reserve University and Robert M. Nerem of the Georgia Institute of Technology.

Bio-artificial liver

Bio-artificial liver tissues are synthetic organs that can replace missing liver tissue in the absence of a donor liver. The technology involves using an autogenic source of cells for transplantation and a biocompatible scaffold for implantation. The biocompatible scaffold is commonly made of collagen-based hydrogels. However, collagen-based scaffolds are susceptible to contraction, which can cause abscesses, which can be fatal. A novel collagen-based scaffold is being developed to minimize this contraction.

The process begins by drawing blood from the patient. The blood is then separated into plasma and blood cells, which are then introduced into a bioreactor. The slices are then arranged between two stainless-steel meshes, preferably parallel, in the bioreactor. The meshes are then pressed to ensure they are flat and have an open surface.


Hemodynamic instability can be the result of a variety of health problems. It can be sudden and unexpected, but symptoms like shortness of breath, weight changes, and fatigue may signal that something is wrong. With better hemodynamic monitoring, it is possible to detect such problems before they become serious, which would improve treatment.

One method of studying hemodynamics is through the use of a hemodynamic simulator. This simulator includes a chamber that simulates the hemodynamic environment of a mammalian heart. The device can be used to study the pulsatile flow of blood and the effects of blood pressure on cardiac function.

RNA vaccinology

Researchers are now looking into RNA vaccinology, or RNA vaccines, to prevent the spread of cancer. This biomedical invention is a promising development in the fight against cancer. The mRNA vaccine theory works by telling a cell to make a protein used by a virus. This triggers an immune response that strengthens the body’s ability to fight the virus itself. Early studies in labs and on animals demonstrated that this method could be successful in fending off cancer.

While RNA vaccines are a relatively new field, there are many advantages to this technology. They are flexible and fast to produce, and they can be developed for a

wide range of illnesses. Although no RNA vaccine has yet received FDA approval, some scientists believe that this technology could prove to be a breakthrough.

Smart medical devices

Smart medical devices can help monitor the vitals of patients with chronic conditions. These devices can also help monitor a patient’s motor functions. The goal is to reduce the need for hospital visits and increase patient independence. Smart medical devices can also help doctors diagnose and treat patients. A smart medical device can even send alerts to doctors when a patient doesn’t take his or her medication. But these innovations are not without their drawbacks.

One of the biggest concerns with IoT medical devices is security. Some IoT devices can be gateways to steal sensitive patient data, posing a serious security risk. These devices must be highly secure to avoid data leakage.


Spectacles are an important example of biomedical inventions that have transformed the human body and society. They have been around for centuries, but only in the recent past have they been used by people in the same way as eyeglasses. During the Renaissance, the use of spectacles became widespread and helped enlarge the scope of literature and the arts. They also made it easier for older people to read small print.

The human eye is made up of a network of layers called the retina, which processes light and transfers it to the brain. The brain then uses this information to produce images. The retina is composed of cones and rods, which are critical to vision. In older people, the retina becomes degenerated, causing permanent vision loss known as age-related macular degeneration. This is one of the leading causes of blindness worldwide, and is a major cause of vision loss in third-world countries.
