Laser-powered “needle” promises pain-free injections

Laser-powered “needle” promises pain-free injections

...Though various techniques have been developed in hopes of taking the "ouch" out of injections, hypodermic needles are still the first choice for ease-of-use, precision, and control.

A new laser-based system, however, that blasts microscopic jets of drugs into the skin could soon make getting a shot as painless as being hit with a puff of air.

The system uses an erbium-doped yttrium aluminum garnet, or Er:YAG, laser to propel a tiny, precise stream of medicine with just the right amount of force.

The laser is combined with a small adaptor that contains the drug to be delivered, in liquid form, plus a chamber containing water that acts as a “driving” fluid. A flexible membrane separates these two liquids. Each laser pulse, which lasts just 250 millionths of a second, generates a vapor bubble inside the driving fluid. The pressure of that bubble puts elastic strain on the membrane, causing the drug to be forcefully ejected from a miniature nozzle in a narrow jet a mere 150 millionths of a meter (micrometers) in diameter, just a little larger than the width of a human hair.

“The impacting jet pressure is higher than the skin tensile strength and thus causes the jet to smoothly penetrate into the targeted depth underneath the skin, without any splashback of the drug,”

Finally a method of administering that may do away with hypodermic needles -- which I know many people dislike. I myself hate needles. I've had bad experiences with nurses missing the vein, that eery feeling of pressure, & one of the worst -- getting a needle in the mouth at the dentist. Multiple times where it felt like my gums were going to explode.

One step closer to the RFID chip implants. Sooner than we think, they'll be able to inject us without us even knowing. We'll just have a routine check-up, or be taken in for questioning, and they'll inject us and set us free.

Then our entire life will be put on file, every activity and moment recorded, and we'll never even know.

Pretty soon a guy will walk up to you and ask... excuse me, does this smell like chloroform?
And you'll get injected and never know.

One step closer? That's pretty much already the case; we already live in a surveillance state, and RFID chip implants exist. It's just a matter of who they want to target. I agree this sort of injection method could pose problems with people getting injected unknowingly; but I don't think it'll be that easy. They'll still need to find bare skin, properly place the device, and you'll still feel something (just not painful). If you're that worried about being secretly injected, you could always go for a blood test following an "interrogation".

Also, you fail to realize they could easily drug you even without something like this. Through your water supply, spiking certain beverages, nano devices attached to anything you may ingest. The truth is if "they" are really after you, there's a very low chance of you being able to avoid it, or even knowing what's happening to begin with.

Nice, more than one application and no lollipops for the kiddos anymore.

You can drink RFID chips, not to mention vaccines. Had your flu shot lately? An ATS thread.

If somebody wants to chloroform you, they can already do so with ease. Just approach from behind and within a few seconds you're out. Or they could use a small needle to quickly inject you, with a variety of chemicals that would knock you out on the spot. Usually if somebody is being targeted like that it doesn't matter what method is used.

Also, I'm not sure if this injection method is even something portable/affordable. Hypodermic needles are rather easy to come by & cheap. A laser-based injector might be something less concealable, or very expensive; and not effective for large doses.

Yes exactly. If the government/ptb want to track you or alter your body chemistry it's already feasible, and probably unavoidable.

As for vaccines, I only had a flu shot once 8 years ago. My most recent shot was a tetanus one that I got after stepping on a rusty nail. Apart from that I despise needles/vaccines & won't get one unless completely necessary.

I wonder what the range on these laser based injections could be?

Could this be modified to automatically secretly shoot people full of fun juice when they enter a casino? or any other place with a preferred drug cocktail?

Enter an eating establishment and you suddenly have an overwhelming craving for exactly what they want you to eat.

etc. etcetera. etc.

I'm sure something like that could go down, but when people begin realizing their cravings/altered state it would be clear what exactly is happening. At that point if enough people were being drugged, first they would get tested/test themselves to analyze whether or not they've been injected; then find out which chemical it is, and its half life. At that point an investigation would be started to tell who is injecting people and when. It wouldn't be hard to prove if casino or other establishment was dosing their customers.

Casinos already pump oxygen and give away free drinks.
It wouldn't be difficult for some shysters to get laser dosing people legalized.

There's also the long/medium distance date-rape aspect. Guys have plenty cause to worry about getting raped too. No one will need spike a drink. Simpy laser dose someone from across the room, and then go 'help' them out the door for the time of their life they didn't know they wanted.
ick.

There's also the weaponized biological warfare aspect. Just load up some nasty bugs, and laser zap people all over the place at leisure from a distance without anyone noticing. Next thing ya know, there's zombies, or spanish flu, or people growing penises out of their heads.

Seems there's lots of crazy strange really messed up ways this innovation can be used to wicked ends.

Um. Giving away drinks or offering drugs isn't the same as dosing somebody without their consent. Drugging somebody without their consent holds the same connotations as rape; so it will never be legal. Secondly, there may be laws on who can and can't legally own the injectors. If a casino was found buying/using them they may get shut down, sued, etc. Lawsuits would be coming from every angle if people started going to casinos to find out they've been secretly drugged -- so no I don't think that would be a viable or smart idea.

Just because the device uses a laser that doesn't mean it's long-range. You still have to press it up against or near the persons skin to administer. I doubt it goes through clothing so just pointing it at somebody wouldn't work anyway. Lastly, a rapist will attempt to rape regardless of what they have at their disposal. It's nearly as easy to spike somebodys drink as it woud be to inject them.

Biological weaponry already exist in many forms, most of which is long-range & could cause much more widespread havoc. That sort of warfare is banned for a reason. Also, there are many other technologies that could cause long-range damage; ones that could blind you, make you deaf, scramble your brain, irradiate you, burn you, and more. Unfortunately the government and elitist psychopaths can use any technology in nefarious/harmful ways.

It's like every other week there's a news story where the headline basically says "We've discovereed another new way to RULE YOU PEASANTS!! YOU WILL OBEY!!!!"

Pretty soon they'll develop a flawless teleportation device and just beam their poison into my veins... Never safe..

A few millimeters.

The laser doesn't inject. The laser is merely used to create a gas bubble that accelerates fluid to a point where it can punch through the skin. It's a different twist on the air-injection systems we already have, and is not all that dissimilar from ink-jet printers.

Could be interesting to see this applied to tattoos, which is probably where it will see the first wide-spread use. The sanitary advantages, controlled depth, and the lack of pain would be a boon. Plus, you'd be looking at a fraction of the ink as there's no splash-back (far less would have to be wiped from the skin).

No.

Biochemistry isn't such a science that one can really create drugs to do this. You can do some simple things - but even that runs into walls.

The inconvenient fact for shadow-government plans to control society is that the human genome has evolved in a highly competitive environment among viruses, spores, and bacteria that, themselves, secrete a wide range of chemicals and compounds.

If we all were identical in our reactions to chemicals, we would be overtaken and destroyed by the many parasites that exist in our ecology. Which is why sex exists, why we have diploid chromosomes, and why our DNA deliberately mutates itself during meiotic division.

All hail the Red Queen.

One day, someone will come up with an ingenious web-site that allows you to search vast volumes of information and links to other sites. That site will track what you search so that they can more effectively target you with advertisements for products you are likely to buy.

One day, someone will create a portable device that has a radio transciever in it capable of refining its position from global positioning satellites. It will have considerable memory on-board with capable data processing. Most importantly, it will have access to sites like the one I just mentioned. Not only will that site be able to present you with targeted advertisements based on your searches - but it can also refine those to products and services based on your location.

But that's not all. Another site will be developed that allows you to post pictures of yourself and record what groups you've been part of (from various stages of an assembly line to military deployments to fraternities). Others will be part of this site, too - and you can see how they are doing and keep tabs with them over the years. They'll even start working with the wireless transceiver in your pocket to tell your friends where you are and what you're doing - so you can all get together and have a good time - just like old times!

Even better - you can scan your portable transceiver at many retailers, allowing you to have access to your bank accounts without the hassle of cards, checks, and other cumbersome devices.

It will be the device that is just too convenient to refuse!

But you're right - we should be worried about the real and present threat - these laser-auto-injectors that will be used to implant us with the far more practical RFID chips.
