INFUSION SET INSERTION DEVICE AND METHOD OF USE
First Claim
1. An insertion device for an infusion set having an infusion set body, the insertion device comprising:
- a barrel defining a pull handle cavity;
a pull handle slideably disposed in the pull handle cavity, the pull handle having an outer surface and defining an infusion set cavity and a release button cavity, the infusion set cavity being sized to receive the infusion set body, the pull handle having a cocked position and an advanced position relative to the barrel;
a release button slideably disposed in the release button cavity, the release button having a loaded position and a released position relative to the pull handle; and
a driver operable to move the pull handle from the cocked position to the advanced position;
wherein the release button extends a first axial distance beyond the outer surface when in the loaded position and extends a second axial distance into the infusion set cavity when in the released position.

10. A method of use for an insertion device with an infusion set having an adhesive patch attachable to a user;
- the insertion device having a barrel defining a pull handle cavity;
a pull handle slideably disposed in the pull handle cavity, the pull handle having an outer surface and defining an infusion set cavity and a release button cavity; and
a release button slideably disposed in the release button cavity;
the method comprising;loading the infusion set into the infusion set cavity until the infusion set contacts the release button, the release button extending a second axial distance into the infusion set cavity; seating the infusion set within the infusion set cavity to extend the release button a first axial distance beyond the outer surface of the pull handle; drawing back the pull handle to a cocked position relative to the barrel; positioning the barrel over an infusion site of the user; triggering the pull handle to move the pull handle from the cocked position to an advanced position; pressing the release button to free the infusion set from the infusion set cavity and fix the adhesive patch to the user.
- the insertion device having a barrel defining a pull handle cavity;

11. An insertion device for an infusion set having an infusion set body, the insertion device comprising:
-
a barrel defining a pull handle cavity, the barrel having a pair of radially opposed trigger button openings; a pull handle slideably disposed in the pull handle cavity, the pull handle having an outer surface and defining an infusion set cavity and a release button cavity, the infusion set cavity being sized to receive the infusion set body, the pull handle having a cocked position and an advanced position relative to the barrel; a release button slideably disposed in the release button cavity, the release button having a loaded position and a released position relative to the pull handle; a barrel spring operable to bias the barrel toward the outer surface of the pull handle and operable to move the pull handle from the cocked position to the advanced position; and a pair of radially opposed trigger buttons operably connected to and biased radially outward toward the barrel, one of the pair of radially opposed trigger buttons being engagable with each of the pair of radially opposed trigger button openings, the pair of radially opposed trigger buttons being operable to maintain the pull handle in the cocked position when the radially opposed trigger buttons are engaged with the pair of radially opposed trigger button openings, the pair of radially opposed trigger buttons being operable to release the pull handle from the cocked position when the radially opposed trigger buttons are disengaged from the pair of radially opposed trigger button openings; wherein the release button extends a first axial distance beyond the outer surface when the release button is in the loaded position and the infusion set body is seated in the infusion set cavity; the release button extends a second axial distance into the infusion set cavity when the release button is in the released position to dislodge the infusion set body from the infusion set cavity; and the outer surface of the pull handle is concave and has an axial concavity depth, the axial concavity depth being greater than or equal to the first axial distance. - View Dependent Claims (12, 13, 14, 15, 16, 17)
