Without needles can inject, children no longer have to fear injections. Japan developed a new syringe without a needle and injected by the pressure of the bubble, just the syringe close to the skin, no pain medication can be accurately delivered to a target location.

Currently there are no needle syringe on the market, they usually rely on the strength of the spring to launch a high pressure fluid, the drug will penetrate the skin to the muscles, but it may damage the nerves, and how many still have some pain.

Shibaura Institute of Technology associate professor Yoko Shanxi team led the development of this new needle-free injector is about 10 cm, which uses the hole applying a voltage to the liquid high-speed launch bubbles, use the power of the bubble burst on the cell out fine , then the fine bubbles inside the cell containing the drug is injected through this hole. After the bubble of gas contracts only drugs reach the affected area.

Since the directivity is very clear, so new syringe for topical treatment can be performed with high accuracy, and the left and right out of the hole is only 4 microns, so little damage to cells.

This needle-free injectors in addition to injection of drugs, but also can include a plant cell into the cell, including the implantation of gene therapy and to carry out, with a wide range of uses. The team prepared to further improve the structure of the syringe, the amount of the drug can be injected, perforation depth more detailed assessment, and cooperation with enterprises, at an early date so that the new syringe to achieve a practical level.
