And this time it’s painless!
Researchers from the UCSB Chemical Engineering Dept. - in collaboration with research teams from UC Berkeley and pharmaceutical company StrataGent Life Sciences, Inc. - have developed a “liquid jet injector,” which could potentially be used to painlessly deliver treatments that are typically administered through needles, like disease vaccinations and insulin.
Though this is not the first needle-less injection device, researchers say this particular version, called the MicroJet, hurts less than previous ones and reduces needle-stick injuries like bruising.
“The MicroJet device delivers drug jets into superficial layers of skin,” UCSB Associate Professor of Chemical Engineering Samir Mitragotri said. “This avoids direct contact of jets with blood vessels and nerves, which are located in deeper skin layers. This helps reduce pain and bleeding, which is commonly observed in conventional jet injections.”
I’m going to go out on a limb here and say that the odds of most of seeing one of these things in action are pretty slim. (I’m still waiting for dentists to adopt the cavity blasting lasers I saw on the news back in the late 1980s.)
Big deal.
I had a needle-less vaccination in Grade School, in Chicago, in the 1960’s.
Big, air-pressure gun thingee. With a jar of vaccine attachd to the bottom, like a tiny glass coffee pot.

I remember those - painless, my ass! :eek:
