Painless efficient syringe?

Scientists in the United States recently invented a high-tech syringes spread drugs through the skin, can in the case of completely painless injection material attached. Media reported that the syringe is likely to completely replace the needle in the near future, become medical workers have been using a new type of injection equipment. Scientists in the United States invented the "injection" was dotted with hundreds of miniature probe, each probe length is only 0.65 mm. When it is in contact with the person's skin, probe on the material will be released to the human body. If a vaccine in this way, the human body can produce corresponding immunity on the day. At present, the development team in mice experiments show that the "injection" is completely painless injection, not only to the spread of the effect is better than the traditional way of injection. Using new "injection" flu vaccine in mice, mice than using traditional needle injection produced by the immune system is much larger. According to the report, if further experiments to prove the effectiveness of the syringe, it is likely to completely replace the traditional needle position, because it not only no damage to human body, still can greatly simplify the process of widespread vaccination. And the "injection" can be placed not only on the flu vaccine, can put any more doctors need to give patients injections of drugs.
