Oliver Blackwell came up with a solution; a syringe
contraption actually using two needles. A small one injects a little local
anesthetic, and when the second larger needle goes in, the prick should be
painless. Blackwell says that the first
injection is “like a fly landing on your palm.”
Plus the needle could be used in millions of procedures, and since both
needles are in one device, the risk of contamination or confusion is reduced. So if you’re afraid of needles; you’re not
anymore.
NOS THEMES:
1.
Role of Skepticism
2.
Role of Motivation and Curiosity

This really intrigued me. The only problem I have with this is how more money it would cost. Also, if any people have allergies with anesthetics this could be a problem. I do think this will help children a lot because most are really scared of needles.
ReplyDeleteI agree but at the same time I also find this possible life changing. Also I don't think the pain is what children are afraid more so than the needle itself. I decided to do some more research on it. Here's a link to another example of this new contraption, http://www.healthtechglobal.com/industry-updates/techno-trends/painless-needle-free-injections-micro-jets.php
ReplyDeleteI agree with everything that all the other comments say. I think that this could have a big use for animals. Instead of having to hold down the animal to keep it from moving around too much, they could use this needle while the animal is asleep. Here is another link about a different type of painless injection that does not use a needle: http://articles.mercola.com/sites/articles/archive/2012/06/26/painless-injector-developed-by-mit-without-needles.aspx
ReplyDeleteI think the statement: "So if you’re afraid of needles; you’re not anymore." could be worded much better. Even if the needle is painless, unpleasant experiences can still cause fear in people who have a history with old needles. Also the needles won't be implement large scale for a while, for that is costly. Third, it should be worded to suggest new patients and children won't be scared, because some of the current population will be.
ReplyDeleteI found an article about a different kind of painless injector. Instead of using a needle, this device uses a high-pressured jet that travels at 340 meters per second through the skin. Since it punctures the skin so quickly, you don't really feel any pain. It surprised me a lot that most of the injections are through the retina and ear. http://articles.mercola.com/sites/articles/archive/2012/06/26/painless-injector-developed-by-mit-without-needles.aspx
ReplyDeleteI found this really interesting because it is a pretty basic comment, but I haven't seen it before! The only problem is that it takes time for the anesthetic to begin working as well as you would still feel the first needle. I found a site for a new device that eliminates needles all together; it uses a laser to inject medicine! http://www.osa.org/en-us/about_osa/newsroom/newsreleases/2012/laser-powered_‘needle’_promises_pain-free_injectio/
