Methods relating to infusion device
First Claim
1. A medication-delivery method comprising:
- inserting a portion of an infusion device into a living being, the infusion device comprising;
a body having a body passageway and a greatest outer perimeter;
a cannula having a portion extending from the body and a cannula passageway; and

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.
