System and device for removing pharmaceutical products
View Patent ↗A system for removing or tranferring a pharmaceutical product from a reservoir including an ampoule with a moveable piston therein and an adaptor which includes, generally along a longitudinal axis, a reservoir connector and an ampoule connector for coupling to the ampoule, wherein the ampoule connector includes at least one locking mechanism which, in a side wall, includes a resilient element generally corresponding to a portion of the side wall which extends along the periphery thereof and, at opposing ends, merges with the side wall.
1. An adaptor for removing a pharmaceutical product from a reservoir with an ampoule in which a moveable piston is arranged, the adaptor comprising:
a reservoir connector comprising a hollow cylinder configured for accepting the reservoir;
an ampoule connector arranged longitudinally relative to the reservoir connector, the ampoule connector comprising at least one locking mechanism which releasably couples the ampoule to the ampoule connector; and
a central part arranged between the reservoir connector and the ampoule connector, the central part comprising two opposing openings through which a front part of the ampoule is visible when connected releasably to the ampoule connector such that air or the pharmaceutical product located in the front part is viewable through the two opposing openings.
2. The adaptor according to claim 1 , wherein the at least one locking mechanism, in a side wall, comprises a resilient element corresponding to a portion of the side wall which extends along the periphery thereof and at opposing ends merges with the side wall.
3. The adaptor according to claim 2 , wherein the at least one locking mechanism comprises a slot and wherein the resilient element extends parallel to the slot.
4. The adaptor according to claim 3 , wherein the at least one locking mechanism comprises two slots and wherein the resilient element extends parallel to the slots.
5. The adaptor according to claim 1 , wherein the reservoir connector comprises at least one recess in a side wall which produces a bulged portion on an inner face of the side wall.
6. The adaptor according to claim 1 , wherein the reservoir connector further comprises a circular portion arranged in the interior of the hollow cylinder configured for accepting an outer diameter of a front part of the reservoir.
7. The adaptor according to claim 6 , further comprising a cannula arranged in an interior of the circular portion of the reservoir connector.
8. The adaptor according to claim 1 , wherein the reservoir connector further comprises a circular portion arranged in the interior of the hollow cylinder configured for entering a resilient septum of the reservoir.
9. The adaptor according to claim 8 , further comprising a cannula arranged in an interior of the circular portion of the reservoir connector.
10. The adaptor according to claim 1 , wherein the at least one locking mechanism resiliently deforms in a radial direction such that the ampoule couples releasably to the ampoule connector.
11. The adaptor according to claim 1 , wherein diameter of the ampoule connector increases outwardly from the central part.
12. The adaptor according to claim 1 , wherein the at least one locking mechanism, in a side wall, comprises a resilient element corresponding to a portion of the side wall which extends along the periphery thereof and at opposing ends merges with the side wall and a slot which defines an opening in the side wall and wherein the resilient element extends parallel to the slot and resiliently deforms in the radial direction.
