U.S. scientists have developed a syringe, injection drug use without a needle.
The results of Professor Ian Hunter and his colleagues at the Massachusetts Institute of Technology published in the Journal of Medical Engineering & Physics. effect devices based on the force with which the electromagnetic field acts on a point charged particle - the Lorentz force. Inside the syringe is a powerful magnet of small size, surrounded by a wire coil. In turn, the piston is attached to the coil, part of which is located inside the vials of medicine. Under the influence of the current coil drives the piston, "throws" of the drug vials at a rate of 314...
