Cartridge insertion assembly
A cartridge insertion assembly including apparatus with a pathway formed therein, a cartridge including a cartridge coupling element connectable to an activation mechanism disposed in the apparatus operative to cause a substance contained in the cartridge to be metered out of the cartridge, and a door pivoted to the apparatus that includes a door coupling element arranged with respect to the cartridge such that when the door is in a fully closed position, the door coupling element couples the cartridge coupling element with a coupling element of the activation mechanism.
1. An apparatus for administering a liquid medication to a subject, comprising:
a housing having an opening;
a surface of said housing configured to adhere to a skin of the subject;
a cartridge containing the liquid medication, inserted longitudinally through said opening into said housing, the cartridge being surrounded on at least three sides by said housing, a long axis of said cartridge being substantially parallel to said surface, and said long axis being positioned off center toward a first side of the apparatus;
a needle retracted inside said housing positioned toward a second side of the apparatus opposite said first side, said needle releasable through said surface; and
a locking latch cantilevered from said housing, said locking latch being in engagement with the cartridge preventing said cartridge from exiting said housing when said cartridge is fully inserted into said housing;
wherein said cartridge includes a proximal end having a septum located thereon from which the liquid medication is discharged, and wherein said cartridge is inserted into said housing with said proximal end inward, said needle puncturing said septum upon full insertion of said cartridge into said opening.
2. The apparatus of claim 1 , further comprising a door at least partially closing said opening.
3. The apparatus of claim 2 , wherein said door is positioned such that when said cartridge is inserted in said opening, closing said door pushes said cartridge fully into the apparatus.
4. The apparatus of claim 1 , wherein said cartridge further includes a rim on a distal end opposite said proximal end.
5. The apparatus of claim 1 , further comprising
a window through said housing, said cartridge being visible through said window.
6. The apparatus of claim 1 , further comprising:
an activation mechanism for activating the administering of the liquid medication, the activation mechanism located in said housing substantially opposite said surface.
7. The apparatus of claim 1 , wherein said surface extends beyond said housing.
8. The apparatus of claim 1 , wherein said surface is substantially rectangular.
9. The apparatus of claim 1 , wherein said long axis of said cartridge is substantially parallel to a long axis of said housing.
10. An apparatus for administering a liquid medication to a subject, comprising:
a housing;
a surface of said housing configured to adhere to a skin of the subject;
a cartridge containing the liquid medication surrounded on at least three sides by said housing, a long axis of said cartridge substantially parallel to said surface, said long axis positioned off center toward first side of the apparatus;
a needle retracted inside said housing positioned toward a second side of the apparatus opposite said first side, said needle releasable through said surface;
an opening in said housing, wherein said cartridge is inserted longitudinally through said opening into said housing;
a door at least partially closing said opening, said door including a ramp positioned such that when said cartridge is inserted in said opening, closing said door causes said ramp to slide and push against said cartridge so as to push said cartridge fully into the apparatus.
