Abstract
An injection system includes a syringe body defining a proximal opening at a proximal end thereof and a distal needle interface at a distal end thereof. The system also includes proximal and distal stopper members disposed in the syringe body, forming respective proximal and distal drug chambers. The system further includes a plunger member configured to be manually manipulated to insert the proximal stopper member relative to the syringe body. Moreover, the system includes a fluid conveying assembly including a penetrating member configured to penetrate the distal stopper member to fluidly couple the proximal and distal drug chambers, a distal exit tube, and a transfer member disposed at least partially around a portion of the penetrating member and defining a fluid passage. A distal end of the penetrating member is disposed in the distal exit tube.
