"The device can be programmed to deliver a range of doses to various depths — an improvement over similar jet-injection systems that are now commercially available."
"While there are several jet-based devices on the market today, Hogan notes that there are drawbacks to these commercially available devices. The mechanisms they use, particularly in spring-loaded designs, are essentially “bang or nothing,” releasing a coil that ejects the same amount of drug to the same depth every time."
“Commercially available jet injectors … provide limited control, which limits their applications to certain drugs or patient populations,” Mitragotri says. “[This] design provides excellent control over jet parameters, including speed and doses … this will enhance the applicability of needleless drug devices.”

siftbotsays...Adding video to channels (Science) - requested by lurgee.

siftbotsays...Promoting this video and sending it back into the queue for one more try; last queued Friday, May 25th, 2012 7:45am PDT - promote requested by luxury_pie.
probiesays...I'll use it, but only if it makes the "PFFFFFFF" sound.
dystopianfuturetodaysays...http://fallout.wikia.com/wiki/Jet
bmacs27says...This certainly looks like an advance, but didn't similar technology already exist?

GenjiKilpatricksays...Like everything else.. Japanese scientist had already invented a cheaper, smaller version years ago
MrFisksays...Too bad blankfist already has AIDS.
deathcowsays...We need volunteers for testing eyeball injections. $5!

Yeah, I remember seeing this on Beyond 2000 about 20 years ago.
I like this snippet from the wiki article you cited:
"1937: First known recorded accidental jet injection by a diesel engine's fuel injector."
Youch!
EvilDeathBeesays...Real life hypo-spray!
Reefiesays...Leonard McCoy would approve.
siftbotsays...Tags for this video have been changed from 'needles, injection, shots, dr, skin, pressure, mit, hypospray' to 'needles, injection, shots, dr, skin, pressure, mit, hypospray, star trek' - edited by messenger
gwiz665says..."We've injected drugs directly into a persons eye, and through the ear drum.. but we've also done something we think is cool.."
SCIENCE, BITCHES!
ReverendTedsays...Let's talk about pain for a moment. It's alluded to, but the video and the Wikipedia article don't really specify.
It's stated that this eliminates the needle, but it's only suggested that this is less painful than a needle injection. ("You don't feel the mosquito proboscis.") I'd expect that even without the needle, the rapid delivery of the medication would still produce a sting.
My brief Google research supports that assumption, with sites like this one and this one saying that the current generation of jet injectors can produce a painful sensation depending on a number of individual factors.
This still allows for a greater degree of control (in situations when that type of precision is necessary), and may be of help to individuals with needle phobias, but I'm skeptical about the real utility over the status quo.
Lendljokingly says...What kind of powdered drugs are you referring to?
Fletchsays...It's the right thing to do.
Maurusays...HIGH ON 100% WHEAT FLOUR
/that being said I know a portion of people who had been promised such a kind of device for use in 3rd world countries, but for whatever silly reason it took like another 20 years and even then the process from lab-ready to mass-production is bound to take another 20- still... SCIENCE
ravermansays...Ah yeah... Mosquito saliva includes an anaesthetic, that's why you don't feel it.
I'm pretty sure the sudden inflation of 5-10 ml's of cold fluid at near the speed of sound into my highly nerve sensitive skin is going to hurt like hell.
Flesh expands around injections because skin and muscle is elastic. However the faster you expand it the more it's going to hurt and damage surrounding tissue.
You're basically being shot, point blank, by a miniature Railgun.
Paybacksays...Most people who are afraid of needles aren't afraid due to pain, but the idea of the thing burrowing away, wiggling under your flesh.
The pain part is pyschosomatic.
