Claim:
1. A device for introducing small volumes of fluid for delivery to a patient through a fluid line, comprising: a y-site comprising a first arm adapted to receive a syringe and a second arm fluidly connected to an upstream reservoir, the reservoir defining an internal volume adapted to receive a volume of fluid; and a fluid obstruction mechanism inside the y-site, the fluid obstruction mechanism configured to selectably block flow of fluid from the reservoir toward the patient, wherein the fluid obstruction mechanism transitions between a first state that permits fluid flow from the reservoir toward the patient and a second state that directs fluid flow from the syringe into the reservoir while blocking fluid flow from the reservoir toward the patient, wherein the syringe pushes the fluid obstruction mechanism to the second state when the syringe is inserted into the y-site.
