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. An insertion assembly for a cartridge in a drug delivery apparatus comprising:

an apparatus housing;

a channel for insertion of the cartridge formed in said housing;

a door to an opening of said channel, and

a doorstop including

a flange and

an extension, and

wherein said doorstop has two modes, an obstructing mode wherein said flange obstructs closing of said door and wherein said extension extends to a path of insertion of the cartridge into said channel and a non-obstructing mode wherein said door may close unobstructed by said doorstop and

wherein, when the cartridge is inserted into said channel, the cartridge engages said extension moving said doorstop to said non-obstructing mode.

2. The assembly of claim 1, wherein further including a base, and wherein said flange is held above said base in said obstructing mode, such that when said door rests on said flange said door protrudes from said housing by a predetermined distance.

3. The assembly of claim 1 wherein said doorstop includes a rotating base and wherein said doorstop rotates from said obstructing mode to said non-obstructing mode.

4. The assembly of claim 1, wherein said doorstop includes a sliding base and wherein said doorstop slides from said obstructing mode to said non-obstructing mode.

5. The assembly of claim 1, wherein in said non-obstructing mode said doorstop blocks an exit of said channel, impeding removal of the cartridge from said channel.

6. The assembly of claim 1, wherein the cartridge includes a flange and said engaging is by said cartridge flange.

7. The assembly of claim 1 wherein said door has at least three states:

a fully open state wherein said door clears an opening to said channel enough to allow insertion of a cartridge into said channel and wherein in said fully open state said door protrudes from said apparatus,

a transport state wherein said door at least partially obstructs said opening and wherein in said transport state said door protrudes from said apparatus less than said protruding during said open state, and

a fully closed state wherein said door obstructs said opening enough to prevent both insertion and removal of the cartridge through said opening;

and wherein said door moves freely between said transport state and said fully open state.

8. The assembly of claim 7, wherein said door comprises a notch on an inside surface thereof, said notch supporting a projection from the cartridge when said door is in said closed state.

9. The assembly of claim 7, wherein said door is mounted on a pivot and wherein said door pivots between said states.

10. The assembly of claim 1 wherein said door includes a coupler, said coupler located such that in when said door is in said closed state said coupler couples a movable element of the cartridge to a motive element in apparatus.

11. The assembly of claim 1, further comprising:

a latch and wherein, in said fully closed state said latch reversibly latches said door.

12. The assembly of claim 1, further comprising:

a latch and wherein, in said closed state said latch permanently locks said door.

13. The assembly of claim 12, wherein in said permanently locked state said door is latched to said doorstop in said non-obstructing mode.

14. The assembly of claim 13, further comprising:

a hook mounted to said doorstop and wherein latching is to said hook.

15. The assembly of claim 1, further comprising:

a stabilizer maintaining said doorstop in said obstructing mode, until a force greater than a threshold value moves said doorstop into said non-obstructing mode.

16. 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.

17. The method of claim 16 wherein opening the door increases a protrusion of the door from the housing.

18. The method of claim 16, further comprising:

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

19. The method of claim 16, wherein said opening and closing include pivoting the door in a plane of an opening of the channel.

20. The method of claim 16, 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.

21. The method of claim 16, wherein said latching is temporary.

22. The method of claim 16, further including:

supporting the door on said doorstop in said transport state.

23. The method of claim 16, further comprising:

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

24. The method of claim 16, wherein said doorstop includes a pin, and wherein upon closing the door with the cartridge inserted, the cartridge diverts said pin.

25. The method of claim 16, wherein said latching is to said doorstop.
