There are a lot of innovations in medicine
around the world that have many beneficial effects for humanity. States like
Japan, Germany, Italy are known for great medical innovations. But, United States remains the world leader, having
produced more than an half of the world’s new medicines over the last decade. This
essay describes some of those amazing innovations in USA, such as Airbike, Veinviewer,
TransMedic and artificial retinas .
For the first time ever, american scientists
have found a way to print out fully-working machines using a 3D printer. The first
item is a fully-functional bicycle made of nylon called the Airbike.It’s a
strong as steel but much lighter. It comes out as a complete bike with no
assembly required. The possibilities for this new technology are endless.
Medical researches hope that with a special cartridge of human cells and
bio-friendly gel, it can be used to print out skin grafts for burn victims.
They have already managed to demonstrate the potential medical uses by printing
out a copy of a human ear in 30 minutes.
Veinviewer is a device that helps nurses to
find veins in real time. It creates a digital image on the skin using
near-infrared light ,locating valves and bifurcations as deep as 15mm. The
purpose of scientists was to create a machine like this, in order to help
nurses determine the best point of insertion. It was proven to increase first
stick success by 100%. Once inserted, Veinviwer can help navigate vessels curves and can even
locate accidental punctures. It was also proven to increase patient satisfaction
Another great device comes by scientists of
USA. It is called TransMedic and its function is to bring a dead heart back to
life. It can reactivate hearts from people who have recently died even if the
heart has stopped beating the orginal body. So far heart transplants come from
brain-dead donors only. The heart is removed from the giver and transported at near-freezing
temperatures. Heart from dead patients have been considered too damaged to
use,because after death the heart quickly becomes oxygen-starved and its muscle
cells die. But, with this device the heart gets the essential infusion of blood
to restore its energy. It pumps warm, oxygenated, nutrient-rich blood through
the organ. TransMedic also maintains the appropriate warm temperature and wetness
around the organ. It has been successfully deployed in more 15 heart
