First Claim
1. A method for inserting a cannula of an infusion set into an infusion site comprising:
- releasably retaining a cannula cartridge of an infusion set on a distal end of a plunger of a cannula insertion device;
releasably retaining an infuser base on a distal end of a housing of the cannula insertion device;
moving the plunger from a retracted position, wherein the cannula cartridge retained on the plunger distal end is remote from an infuser base releasably retained on the housing distal end, to an advanced position wherein the cannula cartridge is engaged with the infuser base releasably retained on the housing distal end and a cannula of the cannula cartridge has been subcutaneously inserted into an infusion site by a cannula insertion needle attached to the plunger.

Abstract
A method for inserting a cannula of an infusion set into an infusion site includes releasably retaining a cannula cartridge of an infusion set on a distal end of a cannula insertion device plunger. The method also includes releasably retaining an infuser base on a distal end of a housing of the cannula insertion device. Subsequently, the method involves moving the plunger from a retracted position, wherein the cannula cartridge is remote from the infuser base, to an advanced position wherein the cannula cartridge is engaged with the infuser base and a cannula of the cannula cartridge has been subcutaneously inserted into an infusion site by a cannula insertion needle attached to the plunger.
