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 cartridge configured for insertion into said channel and a door to said channel, the method comprising:

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

opening the door;

inserting the cartridge and thereby;

shifting said doorstop from said obstructing mode into a non-obstructing mode;

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 channel.

5. The method of claim 1, further comprising,

interconnecting a movable element of the cartridge to a motive element of the apparatus by via 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 of a removal of the cartridge from the 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.
