An Israeli scientist has, after 20 years of work, developed a device that would get rid of the need for needles in certain cases (immunization or anesthetics). The SonoPrep is a hand-held ultrasound device that painlessly opens microscopic pores in a small area of the skin, allowing medication to pass into the bloodstream.

The SonoPrep works by applying ultrasound waves to a small area of skin, about one square centimetre, for about 15 seconds. The ultrasound disrupts a protective membrane under the skin, allowing fluids to flow in or out.
