a body having a first fluid delivery passageway and a second fluid delivery passageway intersecting the first fluid delivery passageway, wherein the first fluid delivery passageway is fed by an inlet port adapted for engagement with an infusion pump connector fitting;
a cannula having a portion that is coaxial with the first fluid delivery passageway, the cannula also having a cannula passageway having an internal width;
a needle guide having a portion positioned within the second fluid delivery passageway and defining a needle guide passageway therethrough;
a septum having a portion positioned within the needle guide, the septum also having an accessible portion that is accessible to an injection needle during normal use of the fluid delivery device, the accessible portion having a width that is at least twice as great as the internal width of the cannula, and
a passageway closing structure oriented in a first position that at least partially prevents fluid from flowing through the first fluid delivery passageway while allowing fluid to flow unobstructed through the second fluid delivery passageway, the passageway closing structure being movable to a second position that at least partially prevents fluid from flowing through the second fluid delivery passageway while allowing fluid to flow unobstructed through the first fluid delivery passageway,
