If you’re queasy about getting shots because you don’t like needles, MIT scientists have developed a new drug injection method just for you.
Instead of pricking the skin, a prototype handheld injector device instead delivers medicine as an extremely thin, exceptionally high-powered jet of liquid, which has enough force to breach skin, yet does so with such precision and speed that it doesn’t cause pain or discomfort, nor does it leave behind a noticeable hole, according to the MIT researchers who created it.
“Skin is flexible and because the hole we produce is so small the elasticity of the skin ‘closes up’ the hole,” said Ian Hunter, an MIT professor of mechanical engineering that led the research behind the prototype injector, in an email to TPM.
“Moreover, the skin repairs the hole in a day or so,” he added.
In a video demonstration of the new injection method and prototype device posted online Thursday, Hunter compared the sensation of getting the drugs injected via a jet to getting bitten by a mosquito — barely noticeable for most people.

This looks great. I'd like to see: how the ampule is attached, a patient receiving an"injection", a demo on aspiration...
Does it check for placement so a blood vessel doesn't get the delivered drug?
So many questions...
Thanks for this site. - 12 months ago

Thanks for posting this, Muse. Can't wait to share with my needle-phobic sister!
