It may a good news for the people which are afraid of needles but have to take injections frequently due to certain disease. A team of MIT (Massachusetts Institute of Technology) scientists have discovered a device that can inject the drugs through the skin at nearly the speed of sound without using needles and could make injection a painless experience.
How the device works?
Actually the device uses a small, powerful magnet and electric current to inject medicine at nearly the speed of sound. Changes in the electric current allow the injector to work in two phases – a high speed phase to enter the skin and reach a certain depth, and a lower-pressure phase to deliver the drug in a slow stream that allows for absorption. The jet injector delivers its drugs through an opening as wide as a mosquito’s proboscis.
Catherine Hogan, a member of the team said to LiveScience:
We think this kind of technology … gets around some of the phobias that people may have about needles. It would certainly be helpful to cure the disease quickly.
Although there are a lot of Jet injector already available in the market but the jet injector made by the MIT team is excellent as others lack the ability to control drug injection speeds.
