Abstract

A medication-delivery method relating to an infusion device specifically adapted for syringe injections.

Claims

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;

a cannula in fluid communication with at least a portion of the body passageway, the cannula having a portion extending from the body, including the portion that is inserted into the living being, and an outer wall that includes a portion that tapers in a downstream direction; and

a septum positioned in the body passageway, the septum having an outer wall that includes a portion that tapers in a downstream direction;

inserting an a straight injection needle through the septum, the injection needle having a length and being straight along the length; and

delivering medication to the living being through the straight injection needle.

2. The method of claim 1, where the inserting the portion of the infusion device includes using an insertion device to insert the cannula into the living being such that the cannula enters the living being at an exterior skin surface and substantially perpendicularly to the exterior skin surface.

3. The method of claim 2, where the insertion device includes an insertion needle, and the using the insertion device includes inserting the insertion needle through the cannula and into the living being.

4. The method of claim 1, where the delivering medication includes delivering medication to the living being through the injection needle from a source that is not connected to a pump.

5. The method of claim 1, where the medication is delivered to a subcutaneous location within the living being.

6. The method of claim 1, further comprising:

removing the injection needle; and

repeating the inserting the injection needle and the delivering when the living being needs another dose of medication.
