System and device for removing pharmaceutical products
View Patent ↗A system for removing or transferring 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. A system for removing a pharmaceutical product from a reservoir with an ampoule in which a moveable piston is arranged and an adaptor which has a reservoir connector arranged longitudinally and an ampoule connector for coupling to the ampoule, wherein the ampoule connector has at least one locking mechanism which, 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;
wherein the adaptor comprises a central part 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 and at least one rib element which extends radially outwardly between the reservoir connector and the ampoule connector; and
wherein the ampoule has a Luer connector with a collar part, which has two circular parts which are separated from one another in the direction of the longitudinal axis by four braces, so that four hollow spaces separated from one another are produced, the hollow spaces being adapted to the resilient element.
2. The system according to claim 1 , wherein the at least one locking mechanism comprises at least one slot and wherein the resilient element extends parallel to the slot.
3. The system according to claim 2 , wherein the at least one locking mechanism comprises two slots and wherein the resilient element extends parallel to the slots.
4. The system according to claim 1 , wherein the reservoir connector has a non-circular cross-section.
5. The system 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 system according to claim 1 , wherein the piston has an ergonomically shaped grip.
7. The system according to claim 6 , wherein the piston comprises a piston rod and a piston stopper, the piston stopper screwed to the piston rod.
8. The system according to claim 7 , wherein the piston rod has a screw part which is screwed into a blind hole of the piston stopper.
9. The system according to claim 8 , wherein the screw part has a gap which extends along a longitudinal axis of the piston and divides the screw part into two parts.
10. The system according to claim 9 , wherein the screw part has an external diameter which is larger than a diameter of the blind hole by a fixed amount.
