Abstract
The invention concerns a needleless syringe () comprising a trigger, a gas generator () prolonged by a gas expansion chamber (), a system for retaining particles and an ejection tube (). The invention is characterised in that the particles are housed outside the ejection tube conduit () and the gases cause the particles to reach inside said tube () by displacing a plunger (), prior to speeding them up by wave shock inside the tube ().
