Infusion Device
The disclosures made herein relate to an infusion device specifically adapted for syringe injections. In one embodiment of the disclosures made herein, an infusion device comprises a body including an accessible surface having a single inlet port therein, an engagement surface having a single outlet port therein, a medication delivery channel extending between the single inlet port and the single outlet port, and an identification feature on the accessible surface of the body adjacent to the single inlet port. The single inlet port of the medication delivery channel is tapered thereby forming a funnel-shaped entry into the medication delivery channel. A cannula is coupled to the body at the single outlet port and is adapted for receiving medication from the single outlet port and transmitting the medication therethrough.
1 . An infusion device comprising:
a body having a body passageway;
a cannula having a portion extending from the body; and
a septum positioned within the body passageway, the septum having a first cross-section positioned parallel to an axis centered in the body passageway, the first cross-section having (a) a first dimension that is parallel to the axis and (b) a second dimension that is perpendicular to the axis and greater than the first dimension;
the septum also having a top and a second cross-section at the top that is perpendicular to the axis, the second cross-section having a cross-sectional area greater than a cross-sectional area of any cross-section of the septum that is parallel to and downstream from the second-cross section.
2 . The infusion device of claim 1 , in which the septum includes an outer wall extending from the top that includes an inwardly-tapered portion.
3 . The infusion device of claim 1 , in which the body includes a top and a bottom, the septum includes a bottom, and the infusion device includes (a) a first greatest distance parallel to the axis between the top of the septum and the top of the body and (b) a second greatest distance parallel to the axis between the bottom of the septum and the bottom of the body, the second greatest distance being greater than the first greatest distance.
4 . The infusion device of claim 1 , in which the body includes an inlet to the body passageway and an identification feature adjacent to the inlet for identifying the body passageway.
