Pain-free medical syringe invented - Polidicks

Scientists have been working on this problem for a while, but a young British inventor based in Somerset may have come up with the solution. Oliver Blackwell's device looks like the typical syringes used in hospitals and doctors' surgeries around the country, with one crucial difference. On the front is a much smaller needle which injects a tiny amount of local anaesthetic to ease the pain of the larger needle which follows. It is essentially two injections in one - the first one, virtually pain-free, paving the way for the second one, which is rendered painless. The first injection is "like a fly landing on your palm", the inventor says. Blackwell, who is 29 and graduated in industrial design from the University of Plymouth, UK, in 2005, says his pain-free needle could be used in millions of procedures every year and reduce the risk of contamination or confusion because staff will only have to deal with one device. "At the moment, if they want to use a local anaesthetic they have to use two needles, find keys and go to the medicine cupboard separately and it all takes time and effort," he says. He involved experts in his design, enrolling the help of two family doctors and a former president of The Royal College of Anaesthetists. They insisted that it should be easy to use, feel and look familiar and meet the needs of patients and doctors.

"Nobody likes having injections, but in my line of work it tends to end up with a needle somewhere." He meets at least one adult every week who is so anxious about needles that their blood pressure rises. Children aged between three and 12 are also particularly prone to needle phobia, he says. "But so much of it is perception rather than reality. For many people it's psychological." Dr McGlennan has sometimes used a local anaesthetic paste on patients' arms which numbs the skin prior to an injection. This eases the pain, but the needle still has to penetrate the skin. Perhaps, in the future, there will be a way of avoiding needles altogether. American scientists have tested a vaccine patch on mice, which cuts out the need for painful needles. Instead, the patch has hundreds of microscopic needles which dissolve into the skin. The researchers say that one day it could be used to enable people to vaccinate themselves against flu, for example. [b]High-speed jet[/b] Several years ago, Japanese scientists claimed they had developed a tiny hypodermic syringe that could be used to give virtually pain-free injections. This could be very good news for people with conditions like diabetes, who require daily injections of insulin to manage their condition. A needle-free injecting device is available on prescription in the UK, says charity Diabetes UK. The insujet insulin administration system is intended for people who are uncomfortable injecting themselves with a needle. When administered, the insulin passes through a small channel, creating a high speed jet that can penetrate the skin and underlying tissue. "Combined with a unique automatic injection system, this results in virtually painless insulin administration," the charity's spokesman Richard Evans explains. Blackwell's device has been through extensive testing but there are still more trials to come before it can be mass-produced. He has won design awards before and is currently working on a range of different inventions - from agricultural machinery to electrical products and medical devices. "It is all about gaining an insight. You take simple information on board from the experts and adapt your thinking based on their skills." Millions of people will be hoping he gets it right.[/quote]

Always thought that getting stabbed with a syringe was more of a psychological thing for people, because in my experience it doesn't really hurt.

I used to be scared of injections. When I was 5 years old.

take it like a man!

Its looking at that fucking needle that hurts the most

It isn't at all painful. Purely psychological.

Needles hurt? :I

You know what else you could do? Sack up and be a man.

I find the most painful part is them taking the needle out of my arm, other than that I don't even feel it go in.

Half the time I don't even notice when they stick a needle in me.

Whatever happened to gritting your teeth and looking away?

The only time you'll notice a needle is when the nurse or doctor inserting the needle misses a vein or it's left inside you for an extended period of time, or maybe when you try to move with it.

These things hurt the most, nurse failed to inject the tube correctly 9 times in my hand. My hand was black the time they got it right.

At school we were having some vaccine and two people passed out. [editline]24th March 2012[/editline] [QUOTE=farmatyr;35272674]These things hurt the most, nurse failed to inject the tube correctly 9 times in my hand. My hand was black the time they got it right.[/QUOTE] Cringe worthy

I used to have to get blood work every month, I have no sympathy for those afraid of needles

The most painful injection I got was when I was injected underneath the tongue. Even then it felt more a itch than actual pain.

post-BCG pain was excruciating. But all in all you can get over it.

It's one of those inventions again that will never be used for some unknown government related reason.

Some needles hurt, have you ever taken a needle to the toe?

No this is one of those inventions that they know people would pay for and therefore they're going to produce em.

Aren't there huge needles that are put into some people's back? I feel for them.

At first I didn't like getting vaccinated, because of the needles. Then, I liked getting vaccinated even more, because of the needles. I like them. I am weird.

I can see why you guys would want to keep your manliness and take the needle with your best Clint Eastwood face on. But i see a good use for these when dealing with people with mental difficulties and other general disabilities. basically, people who freak the fuck out if a fly lands on them.

It's not the pain that I dislike, it's just the thought. I personally cringe at the thought of something being stabbed through my skin and being inside my arm. It's creepy.

Vaccinations don't hurt because of the needles, they hurt because of the medicine going into your arm The needle is just a tiny pinch, the reason people associate it with pain is because of the inflammation that comes when the medicine is injected (which this invention isn't going to help).

I'm pretty much immune to all anesthetics that aren't of the "Knock you the fuck out" type :C Good thing I don't mind needles then I guess.
