Scientists have developed a new method for injecting drugs without a needle. A high-speed, high-pressure ejector can be used to inject drugs through the skin. This method may one day end the era with accident injuries caused by injection.
Scientists unveiled the mystery of this needleless syringe on May 26. It is similar to the injection device in the movie "Star Trek", which can inject various doses of drugs into the skin of different depths according to a predetermined procedure.
