Microneedle injection horrible capsule MIT graduate invention

　　You are willing shot, or are willing to swallow a capsule full of needles it? The answer seems obvious, but the latest invention might make you reconsider. 
　　28-year-old from Massachusetts Institute of Technology chemical engineering graduate student Carl Schoellhammer especially dislike injections. He said: "injections horrible, painful, no one likes."

In addition, every year the problem is not caused by a prescribed additional $ 100 billion in medical expenses, some of which may be due to the injection of drugs through injection, "a lot of people do not want injections, it may be because lazy, there may be no injections feel a little better, but not like needles definitely a big factor. " 

　　Schoellhammer decided to solve this problem, he designed a micro-needle capsule (Microneedle Pill , mPill), also has received a Limassol Wilson - MIT Student Prize of $ 15,000 reward. 

　　mPill surface covered with small needles capsules, the outer covering of the pH of the reaction layer, make swallowing easier. This design is not for fun, Schoellhammer hope can replace conventional injection. Many injectable drugs are made ​​from protein, particularly biological agents, if oral administration of these drugs, these proteins in the absence of the digestive system into the blood will be decomposed. 

　　Schoellhammer represents mPill injections but that is in the body, in this full of stainless steel needle into the right amount of medicine capsules, once the patient swallow it, after reaching the intestine, the surface of the protective layer dissolves, so that these needle prick the intestinal wall into the surrounding, injecting the drug directly into the bloodstream, than the traditional injected pain is much smaller. 

　　Many security issues have been taken into account: These needles are very small, Schoellhammer guarantee even glass or staples such foreign matter, at 90% -95% of the cases can be safe in vivo. mPill has conducted experiments on animals, on the safety and efficacy have been successful. 

　　If you still feel scared, Schoellhammer currently developing another version of the capsule, the use of the drug mixed with sugar, solid needles made. The results are the same, the needle penetrates the surface of the digestive tract, the drug directly to the blood, but this time the needle itself will dissolve, and finally left the capsule without needles. 

　　Schoellhammer currently only created a capsule, he plans to design an improved version, but he said:. "Not technically difficult, that is, outside the small capsule with a needle" Schoellhammer is aimed at those that regularly injected drugs, such as insulin because these drugs only need an easier mode of administration.
