Needleless syringe provided with a piezoelectric triggering system |
摘要 |
The invention concerns the technical field of needleless syringes for injecting an active principle through the skin. More particularly, the invention concerns a needleless syringe provided with a piezoelectric crystal and a triggering device comprising a triggering member and impacting means and, on a triggering device particularly adapted to needleless syringes. The invention is mainly characterized in that the impacting means comprises a latch maintained under elastic stress by being blocked against a stop element and the triggering member is capable of moving the latch to release it, so that it is urged to strike the piezoelectric crystal. Then, the crystal produces an electric arc designed to initiate a pyrotechnic charge whereof the combustion gases will help to expel the active principle contained in the syringe. |
