Abstract
A needleless syringe equipped with an initiating device comprising a triggering device and a pyrotechnic charge, wherein the triggering device contains a triggering member connected to a friction igniter that initiates the pyrotechnic charge by friction. An advantage of the invention is that the syringe produces very limited amounts of noise during operation.
