Say goodbye to injection needles !Injecting a medicine into the body is always painful, especially for children. The latest news from the Massachusetts Institute of Technology (MIT) provides consolation for this.
It is a modified jet injector, a device developed using Lorentz – force actuator. From the ampule in which the medicine is filled a piston pushes out the medicine in high pressure and speed into the body. The tip of the end portion of the ampule through which the medicine ejects is so small as that of a mosquito pin head.
The speed of the ejection of medicine will be equal to that of sound waves in air.
