Abstract

A cap for intake and delivery of a fluid from a syringe is described. The cap includes an outer cap assembly comprising a fluid inlet path and a fluid outlet path and an inner cap assembly configured for insertion into a fluid nozzle of the syringe and to provide selective fluid communication between an interior of a syringe and the fluid inlet path or the fluid outlet path. The outer cap assembly is slidable relative to the inner cap assembly between a first filling position, where the interior of the syringe is in fluid communication with the fluid inlet path, and a second delivery position, where the interior of the syringe is in fluid communication with the fluid outlet path. Syringes including the cap are also described.
