Abstract

A self-injection device ( 100, 200 ), including a pen body ( 108, 208 ) connectable to a pen needle ( 10 ), and a cap ( 104, 204 ) selectively connectable to the pen body ( 108, 208 ) in a first orientation with respect to the pen body ( 108, 208 ) to minimize the length or volume of the self injection device ( 100, 200 ), and in a second orientation to provide sufficient length or volume in an interior of the cap ( 104, 204 ) to house a pen needle ( 10 ) connected to the pen body ( 108, 208 ).

First claim

The invention claimed is:

1. A self-injection device, comprising:
a pen needle:
a pen body connectable to the pen needle; and
a cap selectively connectable to the pen body in a first orientation with respect to the pen body to render the length or volume of the self-injection device insufficient to have the pen needle connected to the pen body, and in a second orientation to provide sufficient length or volume in an interior of the cap to house the pen needle connected to the pen body;
wherein the cap is removable from the pen body and encloses a distal end of the pen body in both the first and the second orientations.

2. The self-injection device according to claim 1 , wherein the first and second orientations are radial orientations with respect to the pen body.

3. A self-injection device, comprising:
a pen body connectable to a pen needle; and
a cap selectively connectable to the pen body in a first orientation with respect to the pen body to minimize the length or volume of the self injection device, and in a second orientation to provide sufficient length or volume in an interior of the cap to house a pen needle connected to the pen body;
wherein the cap is removable from the pen body and encloses a distal end of the pen body in both the first and the second orientations;
wherein the pen body comprises a pen body axial protrusion and a pen body axial recess, and the cap comprises a cap axial protrusion and a cap axial recess;
wherein in the first orientation, the pen body axial protrusion axially abuts the cap axial recess and the cap axial protrusion axially abuts the pen body axial recess; and
wherein in the second orientation, the pen body axial protrusion axially abuts the cap axial protrusion.

4. The self-injection device according to claim 3 , wherein:
the pen body comprises a first body connector disposed within the pen body axial recess;
the cap comprises a cap connector disposed on an interior of the cap axial protrusion axially adjacent to an end of the cap axial protrusion to interact with the first body connector to secure the cap to the pen body in the first orientation; and
the first body connector comprises one of a radial protrusion and a radial recess, and the cap connector comprises a remaining one of the radial protrusion and the radial recess.

5. The self-injection device according to claim 4 , wherein:
the pen body further comprises a second body connector disposed axially adjacent to an end of the pen body axial protrusion; and
the second body connector comprises the one of the radial protrusion and the radial recess that is the same as the first body connector, to interact with the cap connector to secure the cap to the pen body in the second orientation.

6. A self-injection device, comprising:
a pen body connectable to a pen needle; and
a cap selectively connectable to the pen body in a first orientation with respect to the pen body to minimize the length or volume of the self injection device, and in a second orientation to provide sufficient length or volume in an interior of the cap to house a pen needle connected to the pen body;
wherein the pen body further comprises a cartridge container for holding a medicament cartridge in the pen body, the cartridge container having an axial slot therethrough for viewing content of the medicament cartridge; and
the cap further comprises a radial protrusion that engages the cartridge container axial slot to secure the cap to the pen body in the second orientation.

7. A self-injection device, comprising:
a pen body connectable to a pen needle;
a cap selectively connectable to the pen body in a first orientation with respect to the pen body to minimize the length or volume of the self injection device, and in a second orientation to provide sufficient length or volume in an interior of the cap to house a pen needle connected to the pen body; and
an anti-rotation feature for preventing rotation of the cap with respect to the pen body subsequent to connection of the cap to the pen body;
wherein the pen body comprises a pen body axial protrusion and a pen body axial recess, and the cap comprises a cap axial protrusion and a cap axial recess;
wherein in the first orientation, the pen body axial protrusion axially abuts the cap axial recess and the cap axial protrusion axially abuts the pen body axial recess; and
wherein in the second orientation, the pen body axial protrusion axially abuts the cap axial protrusion.

8. The self-injection device according to claim 7 , wherein the anti-rotation feature comprises:
a pair of axially protruding horns disposed on radial sides of the pen body axial protrusion; and
a pair of axial horn recesses disposed on radial sides of the cap axial recess, the horn recesses corresponding to the horns;

wherein the horns interact with horn recesses when the cap is secured to the pen body in the first orientation to prevent relative rotation of the cap with respect to the pen body; and
wherein the horns interact with radial sides of the cap axial protrusion when the cap is secured to the pen body in the second orientation to prevent relative rotation of the cap with respect to the pen body.

9. The self-injection device according to claim 7 ,
wherein the anti-rotation feature comprises:
a pair of axially protruding horns disposed on radial sides of the cap axial protrusion; and
a pair of axial horn recesses disposed on radial sides of the pen body axial recess, the horn recesses corresponding to the horns;

wherein the horns interact with horn recesses when the cap is secured to the pen body in the first orientation to prevent relative rotation of the cap with respect to the pen body; and
wherein the horns interact with radial sides of the pen body axial protrusion when the cap is secured to the pen body in the second orientation to prevent relative rotation of the cap with respect to the pen body.

10. A self-injection device, comprising:
a pen needle:
a body selectively connectable to the pen needle at a first end of the body; and
a cap having an interior cavity, the cap being connectable to the body in a first orientation with respect to the body in which the interior cavity is unable to accommodate the pen needle connected to the body, and in a second orientation with respect to the body that is axially further from a second end of the body than the first orientation, to accommodate the pen needle connected to the body within the interior cavity, the second end of the body being opposite to the first end;
wherein the cap entirely encloses the first end of the body in both the first and the second orientations.

11. The self-injection device according to claim 10 , wherein the first and second orientations are radial orientations with respect to the body.

12. A self-injection device, comprising:
a body selectively connectable to a pen needle at a first end of the body; and
a cap having an interior cavity, the cap being connectable to the body in a first orientation with respect to the body, and in a second orientation with respect to the body that is axially further from a second end of the body than the first orientation, to accommodate the pen needle connected to the body within the interior cavity, the second end of the body being opposite to the first end;
wherein the cap entirely encloses the first end of the body in both the first and the second orientations;
wherein the body comprises a body axial protrusion and a body axial recess, and the cap comprises a cap axial protrusion and a cap axial recess;
wherein in the first orientation, the body axial protrusion axially abuts the cap axial recess and the cap axial p
