First Claim
1. An infusion device comprising:
- a body having a body passageway and a top, the body passageway having an inwardly-tapered portion extending from the top;
a cannula having a cannula passageway and a portion extending from the body, the cannula passageway having a cannula passageway end positioned outside the body, the cannula passageway end having a width; 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 septum 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 septum top surface that includes a septum top surface portion accessible to an injection needle, the septum top surface portion being bounded by a septum top surface portion perimeter that defines a second cross-section that is perpendicular to the axis and that has a greatest width that is greater than the width of the cannula passageway end.

Abstract
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.
