Nope - they improved existing technology - such things were in use more than 30 years ago.

Adirael• 14 years ago

"Nope"? The title says "builds" not "invents". The body of the article reads: "Jet injection technology has been around for quite a while. It's been used in mechanical devices for more than a century".

So yes, they are improving an existing technology, the article says so and they point which improvements they made.

EDIT: Grammar, wording.

It would be insanely cool if this becomes available one day for human use. I hate getting shots with a passion. Heck, something like this might actually prevent the spreading of diseases from needle sharing. I don't know how likely it is that junkies will be able to afford one of these units but I'd imagine that one day the cost would go down enough for regular people to buy one. (In the beginning they will probably cost 10x what they're actually worth.)

hahainternet• 14 years ago

This sort of device has actually been in use for a number of decades. There are associated downsides like biological transfer and the infiltration of skin cells. I'm afraid you'll have to suck it up for a while yet.

Can this be tailored for intravenous use? The tricky thing is calculating the depth of the vein and it's thickness.

Drop one of these off at Insite and they'll figure it out in an hour.

Long time back I saw someone demonstrate an needle free injection using osmosis (or reverse osmosis) on Discovery channel. It was pretty amazing and this article reminded me of that. Unfortunately I can't really find anything like that on Google right now. Can osmosis be used to inject drugs or is my memory completely incorrect?

You may be thinking of DMSO: http://en.wikipedia.org/wiki/Dimethyl_sulfoxide

It's a gel that easily penetrates the skin and can serve as a drug delivery system. The KGB was said to use it to administer poison to assassination victims. Its history has been plagued by controversy, which has slowed down research on its many potential medical uses.

dexen• 14 years ago

The most interesting part is described near the end: they are able to inject powder. The device vibrates the powder to the point it behaves as liquid and thus can be injected easily. Cool :D

Somebody correct me please; I imagine they care about powder because drugs (or vaccines?) in powdered form could sustain longer storage than liquid form.

So I guess we don't have to take pills anymore, just inject it!

raverbashing• 14 years ago

That is indeed a very likely explanation

Remember antibiotics that come as a powder and that have to be mixed at home, and have a very short life after being mixed? While the pill version has a standart shelf life?

I assume hence vaccines that have to be kept in fridges now would come as a powder.

k-mcgrady• 14 years ago

It's probably also much easier to transport.

Star Trek here we come!

Surprisingly accurate prediction.

libria• 14 years ago

As long as it doesn't look like a "real" hypospray, you can avoid the CBS legal team: http://code.google.com/p/moonblink/wiki/Tricorder

I'd love for this to exist, being a hater of needles. But it seems a bit odd to say:

"""The new injector has yet to be tested on people, but has been used on animals, like sheep, without apparent discomfort. "The sheep did not seem to even be aware that they were being injected," Hunter says"""

Are sheep not herd animals that almost never show discomfort or pain? Something to do with not wanting to get picked off by predators? I've never seen a sheep act hurt. I've even seen one get its back broken by a horse and it just lay there like it was fine.

olliesaunders• 14 years ago

I sort of hope you’re right because the idea of a technology that could inject things into people without them even knowing freaks me out a little bit.

astrofinch• 14 years ago

One solution to this problem would be to regulate the injectors so that they had to put a mild, distinctive kind of pressure on your skin as they injected into it.

SoftwareMaven• 14 years ago

They will still flinch when you poke them. Reactions to chronic discomfort may be hidden, but acute pain still causes a reaction (note: this is from my experience growing up in the fields around farm animals. I've not tried a controlled experiment, nor do I know of one :)

andrewflnr• 14 years ago

Not a scientific account, exactly, but I seem to recall from reading James Herriot that some animals just do not care about injections, at all. Same with (IIRC) some cows and dogs, at least. This new device sounds cool, but I'm not confident it doesn't hurt.

Fice• 14 years ago

Inject drugs into people without making them notice? This makes a dangerous weapon.

uptown• 14 years ago

Since you can already easily achieve this through the use of food or drink as the delivery mechanism, I don't see how this changes things much.

bendauphinee• 14 years ago

With food or drink you have to at least have some access to it. With an injector, you could hit someone on the street just by walking by/near them. I make my own food, but I walk by hundreds of people every day.

dhughes2• 14 years ago

Everything old is new again, at an industrial park near me a company back in the late 1970s early 1980s developed a similar device.

  It used air pressure or some way of forcing medicine through the skin without needles it's called the Preci-Jet.

swalsh• 14 years ago

e-ink was invented during the 70's too! Sometimes inventions are made before their time.

dhughes2• 14 years ago

Sure, I remember reading about purple stuff found in a swamp being studied and a few years later OLED is in my hand as the screen on my phone.

huhtenberg• 14 years ago

When I was a kid, they used the exact same injectors to vaccinate us in school. That was in mid-80s. This thing was indeed virtually painless and left a funny air bubble under the skin that disappeared in an hour. As far as I was concerned it was awesome. But apparently it had some problems (infections?) and the program ended as quickly as it started.

schiffern• 14 years ago

>left a funny air bubble

>apparently it had some problems

Air emboli?

mbrameld• 14 years ago

An air embolism would only be a problem if it was in a blood vessel. Those injectors were intramuscular and the air just diffused back out through the tissue.

blahedo• 14 years ago

The posted article mentions that the base technology is not new, that the problem with the existing variants was infections, and that the reported device is a refinement on this decades-old technology.

1as• 14 years ago

Slightly off-topic, but isn't it interesting how often news like this is broken with MIT as the subject of the headline: "MIT builds…", "MIT discovers…", etc?

In general, reports originating from universities tend to be billed as "Scientists discover…, "A report from Harvard suggests…", and the like.

Its indicative of, and certainly amplifies, the MIT brand.

Archio• 14 years ago

Exactly, I've noticed this time and time again.

> MIT discovers ... > MIT students make brilliant startup ... > MIT professors build ...

Meanwhile, let's say something originated from RPI. It would say,

> Scientists discovered a new vaccine that ...

I think it helps the pull- MIT is a brand name, so people will click the link.

jakejake• 14 years ago

I experienced one of the older versions of this injector at a free vaccinations offered by my college. I'd say it hurt more than the needle, but it was faster. They were also vaccinating a huge line of thousands of students fairly quickly.

After the injection was done it looked like there was a tiny worm sticking out of my arm (where the vaccine was kinda leaking out). Weird!

velodrome• 14 years ago

Wow, pretty amazing. It's a lot like a Star Trek "hypospray."

Anyway, I can imagine a lot less kids crying when getting their inoculation. Seeing a huge needle (to a child) is quite scary and this device does not look scary at all. In fact, it looks a lot like a toy.

I wonder how they can reuse the device between patients (probe ejection)?

In reality, I fear this tool will never see the marketplace due to the medical industry stranglehold.

moocow01• 14 years ago

It would be great if they could get this down to almost no cost so its accessible to and preferred by hard drug users. While drug abuse and addiction is an extremely sad human habit, it is magnified by the side effects of needle sharing and the diseases that are typically accidentally passed on by users.

On top of it if this was paired with cheap electronic regulation mechanisms it could at least attempt to discourage a user from overdosing. I know its somewhat of an odd proposal but I think there could be potential here to help a population thats already down and out from succumbing as frequently to death and disease as they do today.

scoot• 14 years ago

Why discourage the Darwin effect?

rsheridan6• 14 years ago

Even if you don't care about the health of IV drug users at all, they spread disease to other people, and when they show up at the hospital it's everyone else who ends up paying the bill, since they usually have no money.

donniezazen• 14 years ago

Psychedelic drug abuse is so widespread because cure to addiction of such drugs is not a priority by drug companies and government. They are also not so interested in research in these drugs. These problems are result of our own ostrich response.
