Getting vaccinated is very important to maintain health, but the fear that most of us often face is not just in our childhood, but also when we grow up, because of the injections through which we get medicines. If only were the science to develop a better mechanism of getting vaccinated, most us would have fears. Just to ease out this fright, MIT researchers have actually made a new medical device, which is a high-pressure jet which is ejected out of a nozzle. The high-pressure jet injection also has controlled doses at different depths.

The jet-injectors have been around for a while, but they were not as typical. What can get them to take off in the market is to have them be able to inject high-pressure doses at the speed required. Previously, that was not the case. Now the electricity-controlled jet-injectors can do that. It is especially good for deep injections or vaccinations required to be given deeper in the skin. For children, it is easier to get past their skin, but for adults a deeper pressure is required in comparison.

Also, these jet-injections avoid needle-stick injuries. Some negligent health-care providers who try to use a needle twice would be prevented from this. The MIT engineers are also working of injections for retina of an eye, for middle and inner ear to give drugs safely through these jet-injections. Further details on this newly developed device could be found in the journal Medical Engineering & Physics.
