Japanese inventor creates needle-free injection

Needle Free Injection

Were you one of the kids who were scared of needles? Are you still scared of them? Well inventor Yoshoi Oyama has developed a needle free injection which he has lovingly dubbed, “Mother’s Kiss”. The container uses air pressure in order to deliver the medicine. In poorer countries, where needles are sometimes reused and spread infection, Oyama’s creation would eliminate the risk. Once costs can be cut down making Mother’s Kiss a more economical alternative to traditional needles, we may see Oyama’s invention all over the world. National Geographic has a video of it in action.

  1. Don’t count on it hitting the US too soon – a device like this has existed since the 1960’s called the Jet Injector, and a similar device called the Ped-O-Jet. A company called Bioject currently makes the Biojector 2000, which has been available to hospitals for several years. It’s already in use in poor countries and some military centers where many people need to be immunized efficiently. The early models sometimes left distinctive scars, even without breaking the skin, and was said to feel similar to getting hit in the arm with a baseball bat.

  2. Bioject is selling needle-free devices right now, and they have been developing and refining this technology for decades now. They have a new spring powered injector coming soon called the I-Ject and that product is much more likely to make a splash in world markets in the near future.

  3. Actually, I had something like this at the dentist a few years ago. I have a crippling phobia of needles, so my dentist got hold of and air pressure thingy so i could have a root canal. Felt like being jabbed with the blunt end of a pencil. Only problem was it didnt work as effectively or for as long as an injection, but it did the job.

  4. I had an air powered injection when I was in the army some 20 years ago, not only has this already been invented but it has also been in use in the US for a number of years.

  5. Needle free injectors have been around for a very long time. Maybe this guy has some new mechanics behind the concept, but the concept is hardly new.

    My wife used a needle-free injector for insulin for years … but finally gave it up. The problem with them is that you cannot guarantee the full dose made it under the skin. Skin varies a lot in thickness and density, and callouses, hidden scar tissue, any number of factors can prevent the pressure from delivering the medication as deep as it needs to go to be effective. There is often no indication this has happened. After many, many incidents of high blood sugars after an injection, my wife realized the flaws in this delivery system outweighed the benefits. Needles can be made so fine that you barely feel them … and it is much harder to mess the injection up.

  6. Although I am deathly afraid of needles, and I find this a viable option, if offered instead, my biggest concern is about the medicine or vaccine being injected. I mean right now we think the medicines are safe, but what about the effect of future generations?
    All I have to say about modern medicines safety is Thalidomide. The whole thing happened in the 1960’s but still close enough that it has effected my life as a 25 year old. If you don’t know about Thalidomide, you should look it up. It is not only a sad thing, but I see it is a warning for the future. The articles are informative and interesting, as well as heart breaking.

  7. When I joined the Marines in ’89, they were using a similar method to inject all of us with vaccines. I developed a scar on my shoulder as a result. It started off as a small bump, now, 21 years later, it’s a long scar that stretches across my shoulder.
