Star Trek-Style Needleless Injections Now a Reality
High-pressure jet designed for those who hate needles

(Newser) – It's like something out of Star Trek: a needleless injection that can deliver medicine painlessly (well, nearly painlessly). Researchers at MIT have unveiled a high-pressure jet for delivering medicines to a range of depths beneath the skin, reports the Daily Mail. "We think this kind of technology ... gets around some of the phobias that people may have about needles," said a member of the team that developed the jet-injection system.

The injector works through something called a Lorentz-force actuator, a powerful magnet attached to a piston inside a drug-filled vial. When a current is applied, the magnet ejects the capsule at very high pressure, puncturing the skin with no more pain than a mosquito bite. Inventors have made similar devices before, but this is the first one that can adjust for different depths and pressures—low for a baby being immunized, say, and high for an adult getting an injection.

When I joined the Navy in 1963, We got all our shots in one dose delivered by a high pressure air gun, so how is this supposed to be something new? The system shown is different but the process is the same. Those older ones did make a rather large hole in your arm, and hurt like hell!

Just as "anti-matter" existed back when "Star Trek" was airing in primetime,so needless injection.The hypospray wasn't something the writers came up with out of their imaginations.
