Abstract:
1. A fluid delivery device comprising: a body having an inlet port, a fluid delivery passageway extending from the inlet port, and an inlet boundary extending upstream and downstream from the inlet port parallel to an axis centered within a portion of the fluid delivery passageway; a cannula having a portion that is coaxial with a portion of the fluid delivery passageway, the cannula also having a cannula passageway having a smallest internal diameter; and a non-split septum having an outer surface that includes an exposed portion located within the inlet boundary and a remaining non-exposed portion, the exposed portion having a greatest width that is greater than twice the smallest internal diameter; the fluid delivery device being configured such that an injection needle that enters the exposed portion of the non-split septum in a downstream direction and exits the non-split septum (a) through part of the remaining non-exposed portion that is substantially perpendicular to the axis or (b) through part of the remaining non-exposed portion that has a tangent that is not parallel to the axis and that borders open space within the fluid delivery passageway, exits the non-split septum into open space that is (c) within the first fluid delivery passageway and (d) downstream of the part through which the injection needle exited.
