Japanese scientists developed the injection technology without a syringe


Injection without needle and syringe

The authors of the new technology are a group of scientists from the University of Osaka, headed by Professor Nakagawa. Instead of the traditional syringe for the introduction of the vaccine, a patch microneedle is used. It is made of a soluble material impregnated with a medicament. When applied to the skin, the tissue painlessly dissolves, and the vaccine gets inside.

The new technology has undeniable advantages. As is known, an expert is required to perform the injection, which is expensive and not always possible. In addition, many people are afraid of panic attacks. Prior to this, attempts were made to create microneedles based on silicon or metal. But this was not entirely safe, because after the injections, fragments remained in the skin.

Patch-microneedles are spared from such a lack, as they completely dissolve. In tests with influenza vaccine of three types, encouraging results were obtained – all subjects had no negative reaction.
