Abstract

An aspect of some embodiments of the current application is a doorstop to a drug delivery apparatus that encourages a user of the apparatus to perform the proper usage steps in the proper order. For example, a user may be expected to receive an injector in a transport state, open it to an open state, insert a cartridge, and/or close the cartridge before operation. The doorstop may have an obstructing mode, optionally preventing closing of the door. The cartridge may optionally have a non-obstructing mode allowing closing of the door. Inserting the cartridge may optionally cause a doorstop to move from the obstructing mode to the non-obstructing mode. In the non-obstructing mode the doorstop may optionally prevent removal of the cartridge.

Claims

1. A method of preparing a drug delivery apparatus for use, the apparatus including a housing having a insertion channel and a medicine cartridge configured for insertion into said insertion channel and a door to said insertion channel, the method comprising:

supplying the apparatus in a transport state wherein the door at least partially blocks the insertion channel and wherein a doorstop is in an obstructing mode to obstruct movement of the door into a fully closed state;

opening the door, the door being pivotable relative to the insert ion channel to open or dose the insert ion channel, the door being pivotable about a first axis parallel to a plane of an opening of the insertion channel;

inserting the cartridge into the insertion channel and thereby shifting said doorstop from said obstructing mode into a non-obstructing mode, the doorstop being rotatable about a second axis which is perpendicular to the first axis;

closing the door; and

latching the door.

2. The method of claim 1 wherein opening the door increases a protrusion of the door from the housing.

3. The method of claim 1, further comprising:

supporting a projection from the cartridge on the door when the door is in said closed state.

4. The method of claim 1, wherein said opening and closing include pivoting the door in a plane of an opening of the insertion channel.

5. The method of claim 1, further comprising,

interconnecting a movable element of the cartridge to a motive element of the apparatus by said closing, wherein said interconnecting is via a coupler mounted to said door.

6. The method of claim 1, wherein said latching is temporary.

7. The method of claim 1, further including:

supporting the door on said doorstop in said transport state.

8. The method of claim 1, further comprising:

impeding by said doorstop a removal of the cartridge from the insertion channel when said doorstop is in said non-obstructing mode.

9. The method of claim 1, wherein said doorstop includes a pin, and wherein upon closing the door with the cartridge inserted, the cartridge diverts said pin.

10. The method of claim 1, wherein said latching is to said doorstop.
