Developed a bandage that can replace injection

It would be nice if doctors stopped poking us with his syringes with needles. I know a lot of adults who are terrified of injections. Even more than children. But there is one very promising way to deliver the vaccine into the person's bloodstream without injections and pain. This method is a special patch, which has developed a bio-engineer Kasia Savicka from new York's stony brook University.

Under normal conditions, human skin does not miss the large molecules. So Kasia had to come up with a way to overcome this smart biological barrier. The decision came suddenly. In the laboratory of the University Kasia some time explored the absorbent polyvinylpyrrolidone, which is able to literally pull the liquid out of human skin. The thing is that if this dehydrated skin apply any drug, it widely opened the pores easily let him inside to bypass the natural protection.

Within a few years Kasia has improved this process by combining the polymer with different vaccines. In the end, she has developed a patch that allows the skin to absorb the molecule is 250 times larger than those which it can absorb under normal conditions. This is really a very important achievement for medicine, because in the world today have enough problems with vaccination of people from dangerous diseases.





The benefits of the miracle patches enough. The mere fact that they are very compact and can be stored without special refrigerators up to 8-10 weeks, already makes them indispensable in hot African countries. Should we say that the person does not feel any pain at the time, as the vaccine is absorbed into the skin and enters the bloodstream.

Kasia Savicka already received a gold medal and Grand prize in the amount of $ 15,000 in the competition of inventors. Now she is waiting for the patent office will issue its working properly, after it lined up representatives of different pharmaceutical companies who are ready to bring her idea to the international level.published
