Abstract

A method for mounting an infusion set to an infusion site includes adhering an infuser base of the insertion set to an infusion site on a user'"'"'s skin and inserting a cannula cartridge of the infusion set into an opening of the infuser base such that a cannula of the cannula cartridge is subcutaneously inserted into the infusion site. Subsequently, the method includes removeably attaching a hub of the infusion set to a barb of the infuser base such that a hub needle of the hub pierces a self-sealing septum of the cannula cartridge, thereby creating a fluid pathway from the hub needle to the cannula. In the method, the attachment of the hub to the barb is such that user-controlled three-hundred and sixty (360°) rotatable motion between the hub and the barb is provided.

Claims

1. A method for mounting an infusion set to an infusion site comprising:

adhering an infuser base of the insertion set to an infusion site on a user'"'"'s skin;

inserting a cannula cartridge of the infusion set into an opening of the infuser base such that a cannula of the cannula cartridge is subcutaneously inserted into the infusion site;

removeably attaching a hub of the infusion set to a barb of the infuser base such that a hub needle of the hub pierces a self-sealing septum of the cannula cartridge, thereby creating a fluid pathway from the hub needle to the cannula and mounting the infusion set on the infusion site;

wherein the attachment of the hub to the barb provides for user-controlled three-hundred and sixty (360°

) rotatable engagement between the hub and the barb.

2. The method of claim 1 further including the step of loading the cannula cartridge partially into the opening of the infuser base before the adhering step.

3. The method of claim 1 wherein the inserting step is accomplished with a cannula insertion device.

4. The method of claim 1 wherein the adhering and inserting steps are accomplished with a cannula inserting device.

5. The method of claim 1 wherein the attachment of the hub to the barb provides for user-controlled 360°

rotatable engagement between the hub and the barb via a gripping engagement between at least one resilient band of the hub and the barb.

6. The method of claim 1 wherein the attachment of the hub to the barb further provides for at least one of user tactile feedback and user auditory feedback of hub rotary motion by cooperation between a plurality of projections on the infuser base and a plurality of indentations on the hub.

7. The method of claim 1 wherein the attachment of the hub to the barb further provides for at least one of user tactile feedback and user auditory feedback of hub rotary motion by cooperation between a plurality of projections on the hub and a plurality of radially-spaced indentations on the infuser base.

8. The method of claim 1 wherein the adhering step is accomplished using an adhesive pad of the infuser base.

9. The method of claim 6 wherein the projections are hemispherical and the indentations are circular in shape.

10. The method of claim 1 wherein the attachment further provides for rotary motion of the hub upon a minimum user applied force of 0.05 lbf.

11. The method of claim 1 wherein the attachment of the hub to the barb further provides a predetermined resistance to hub rotary motion by cooperation between a plurality of projections on the infuser base and a plurality of indentations on the hub.

12. The method of claim 1 wherein the attachment of the hub to the barb further provides a predetermined resistance to hub rotary motion by cooperation between a plurality of projections on the hub and a plurality of radially-spaced indentations on the infuser base.
