Needle-free injection system

[DanG]

Maybe some of you might like the new subcutaneous delivery systems that is in test phase - sounds techy and fascinating, but I have no problem with the needle sticks.

Here is the story:
======================
Needle-free injection system using pyrotechnical propulsion

PYROFAST is an innovative needle-free injection system with novel pyrotechnical gas propulsion that provides accurate and comfortable drug delivery through the skin for intra-dermal, subcutaneous, and intra-muscular injections of liquid and solid (lyophilized) drugs.

The needle-free injection occurs within 40 msec; a very fine, high-pressure jet stream of liquid medication painlessly penetrates the skin, depositing medication in the tissue beneath. The skin orifice caused by the jet stream is 4 times smaller than the orifice caused by a conventional needle injection. Therefore, needle-free injection reduces skin trauma and pain and leads to better patient compliance by eliminating patient’s needle-phobia. PYROFAST allows patients to self-administer their injectable medication easily.

My pharmacist told me about this today. I don't have a problem with needles either, but regardless, we're all going to get scarring and whatnot from them. Hopefully this new system won't have any similar kinds of side-effects. I'd love to volunteer as a test subject.

This has actually been around for a long time. It never really took off. I don't know if it was not being absorbed properly or the small amount of insulin being delivered was not accurate. I was excited about this in the early 80s then it went away. Maybe they have made it better now.

I got my shots when i first came into the military with a gun that shot the vaccine in with air. If you flinched or moved it would slice open you arm like a knife. I saw a few people come out of the line with bandages in the arm big ones . Also the military would give flu shots with the air gun so the idea has been around for awhile. I hope they have improved on it a lot scince than

As a 13 yr old I had my TB shot with a device that shot it through the skin.. resulted in a small roundish scar.. it hurt a bit but not as scary as the giant needles they were using on some kids..not sure why they got needles, unless we were actually guinea pigs for the shots..I remember talk that it was new...

Hey! Can I run it in reverse to get blood for my meter?!

As some one here said that it is old technology, the problem is that sometimes what it was injecting went strait into your bloodstream.

I believe this Pyrofast product is the same delivery principle, but a modern high tech system that is not dependent upon large compressor machinery stuffs to do the task. I am thinking that the words "...pyrotechnical gas propulsion..." indicate that the system produces the same type of compressed air delivery of stuff, but using a new pyrotechnic process. The picture of a sample product looked like the thing is no larger than the current insulin pen devices. Google Pyrofast and the first link is to a german gmbh firm - the remaining google links are to some gaming sites - pyrofast must be hot in the gaming industry. But, the gmbh site has a picture of the pen device. I read about the device in the November NASA TechBriefs magazine.

This is indeed old tech. I had a devise about 15 years ago that held insulin "r" in this case in a resovoir, and it worked on the same principle as a pen. Except it used air to inject. I hated it and soon stoped using it. It would leave huge bumps in my arm, leg, wherever and it hurt like **** sometimes too:(
