Automatic injector having door block until proper cartridge insertion
First Claim
1. An automatic injector device for delivering a pharmaceutical substance from a cartridge having a protruding edge, said cartridge positioned in a housing of said device, said housing comprising:
- a cartridge bay having an opening sized to allow passage of said cartridge into said cartridge bay;
a door to said cartridge bay opening, said door having an unlatched position and a latched position, said door being configured to move between the unlatched position and the latched position along a trajectory;
an interference element having a deflected orientation comprising an unstressed configuration of said interference element and an inflected orientation comprising a stressed configuration of said interference element, wherein said interference element is configured to mechanically interfere with movement of said door along said trajectory in said deflected orientation, and wherein said interference element is configured to not mechanically interfere with movement of said door along said trajectory in said inflected orientation; and
a contact interface that is elastic and positioned along said cartridge bay such that when said protruding edge engages said contact interface, said contact interface shifts said interference element into said inflected orientation.

Abstract
An automatic injector device for delivering a pharmaceutical substance from a cartridge having a protruding edge, positioned in a housing cartridge bay having an opening sized to allow passage of the cartridge; a door to the cartridge bay opening, the door connected to the housing and having an unlatched position and a latched position, the door defining a trajectory between the unlatched position and the latched position; an interference element having a deflected and an inflected orientation, the deflected orientation mechanically interferes with the trajectory of the door; and a contact interface positioned along the cartridge bay and extending up to the protruding edge, the contact interface mechanically couples the deflected and inflected orientation with a sensed contact of the protruding edge, such that when the protruding edge is positioned at the contact interface, the contact interface shifts the interference element into the inflected orientation.

12. A method for positioning a cartridge having a protruding edge in a housing of an automatic injector, said housing having a door for covering a cartridge bay of said housing that is configured to receive the cartridge, the method comprising:
-
mechanically interfering, via a deflected interference element that is in an unstressed configuration, with movement of said door through a trajectory of closing said door; inserting said cartridge into said cartridge bay of said housing; pressing said protruding edge of said cartridge against a contact interface that is elastic and positioned along said cartridge bay; shifting the position of said contact interface, thereby inflecting said interference element into a stressed configuration away from said trajectory of said door; and latching said door in a closed position. - View Dependent Claims (13, 14, 15, 16)

17. A method for positioning a cartridge having a protruding edge in a housing of an automatic injector, said housing having a door for covering a cartridge bay of said housing that is configured to receive the cartridge, the method comprising:
-
mechanically interfering, via a deflected interference element, with movement of said door through a trajectory of closing said door; pushing said cartridge away from said cartridge bay when less than 95% of said cartridge is inserted into said cartridge bay; inserting at least 95% of said cartridge into said cartridge bay of said housing before said protruding edge of said cartridge is pressed against a contact interface; pressing said protruding edge of said cartridge against said contact interface positioned along said cartridge bay; shifting the position of said contact interface, thereby inflecting said interference element away from said trajectory of said door; and latching said door in a closed position. - View Dependent Claims (18)
