If you ever wondered what getting a tattoo feels like, just watch this super slow motion video showing up close shots of the tattoo needle relentlessly stabbing people's skin over and over again so that the ink sets underneath. It's hypnotic and rhythmic actually, if you're the type to enjoy seeing skin bounce up and down like jello and like to think about pain and your own mortality every now and again.
Inserting an IV is as common a medical procedure as stitching up a wound, but finding a vein through trial and error means it can still be painful for a patient. And researchers at The Hebrew University of Jerusalem want to change that with a handheld robotic device that uses infrared and electrical sensors to precisely pinpoint a vein and painlessly insert an IV.
Even if it means protection from dangerous, even fatal diseases, having a needle jabbed into your skin and liquid sickness squirted into your flesh is no fun for anyone. There are other needleless injection solutions out there, but a new microneedle array made completely out of dried sugar promises to make vaccination not only painless, but dirt cheap.
It's counter-intuitive, but a new syringe design could eliminate the pain when getting a shot by using two separate needles that work in quick succession. A technique that could be hard to accept for those who hate being pricked.
Nanobioscience's AdminPatch sounds like a pretty amazing way to deliver drugs into the body: it's got a metal surface covered in millions of tiny microneedles that puncture the skin. You may instantly think "Ouch!" but since these are so small and pierce the skin shallow enough to avoid pain receptors, the system is apparently painless.
Most of our childhoods have already been ruined by needles at the doctor's office, but one Japanese inventor thinks he's come up with the perfect pain-free, needle-free injection to sooth tomorrow's lucky kids. Called Mother's Kiss, the device would theoretically eliminate the need for needles and even existing needle-free devices, which use gas or air pressure to deliver drugs (think primitive Dr. Crusher). Instead, the seemingly simple device uses tiny plastic ampules to deliver life saving meds to the needle-averse. National Geographic has a video, but it doesn't embed, so check the link for more on inventor Yoshoi Oyama and Mother's Kiss.
We've brought you inventions that aim to replace the scary-looking hypodermic syringe before, but this new design reinvents the device in a kid-friendly package. Designed by Christopher Holden, a student at Northumbria University in the UK, MediDome combines drug and needle in a stick-on blister, designed for a single use only. So it reduces the risk of needle-stick injury, and looks much friendlier to kids. You simply stick it on, and compress it until the drug is delivered: it's even got an integrated alert system to check you've not ruptured a vein, and a built-in tamper warning. It's now being patented, so it's a product we might actually see for real sometime.
Dutch designer Hån Pham has devised the Urban Needle Box to tackle the problem of used, and possibly infected, needles lying around in public areas. A kind of pocket-sized safety box for sharps, the Zippo-lighter-sized device should be cheap to make, and looks easy to use. The concept might have just one difficulty to overcome: reminding someone who's brain is fizzing with Smack to actually put needles in it.
