Self-aspirating dental cartridge syringe for infiltration and block anaesthesia.
The syringe has an ergonomic design that provides optimal balance and a tactile control of the injection. Automatic aspiration occurs by a light pressure on the plunger. The self-aspiration without retraction minimizes the risk of needle tip movement in the tissue.
The original Aspiject dental cartridge syringe was developed by Rønvig in collaboration with Dr. odont. h.c. Hans Evers, Sweden.
