Abstract

A system for medicament preparation and delivery is provided. The system includes a housing having a chamber for containing a liquid and a plunger movable within the chamber for drawing and dispensing liquid. The plunger and the housing are configured such that the plunger is movable via a drive mechanism capable of engaging a side of the plunger or alternatively by applying a force to a top of a shaft of the plunger.

Claims

1. A system for medicament preparation and delivery comprising:

(a) a housing including a chamber for containing a liquid; and

(b) a plunger movable within said chamber for drawing and dispensing liquid, said plunger and said housing being configured such that said plunger is movable via a drive mechanism capable of engaging a side of said plunger wherein a top of a shaft of said plunger is connectable to a manually operable plunger interface.

2. The system of claim 1, further comprising a toggle for switching between movement of said plunger via said drive mechanism or movement of said plunger via said force to said top of said shaft of said plunger.

3. The system of claim 2, wherein said shaft of said plunger is configured with at least one groove for engaging said drive mechanism.

4. The system of claim 3, wherein said at least one groove is a spiral groove.

5. The system of claim 3, wherein said at least one groove engages a drive element of said drive mechanism.

6. The system of claim 3, wherein said toggle is capable of engaging said at least one groove.

7. The system of claim 1, further comprising said drive mechanism.

8. The system of claim 7, wherein said drive mechanism is attachable to a side wall of said housing.

9. The system of claim 8, wherein said drive mechanism includes a motor having a drive gear.

10. The system of claim 9, wherein said drive gear is a pinion.

11. The system of claim 9, wherein said drive gear is a worm drive gear.

12. The system of claim 9, wherein said drive gear is capable of engaging at least one groove in said shaft of said plunger.

13. The system of claim 9, wherein said shaft releasably engages a shaft gear which is capable of engaging said drive gear.

15. The system of claim 7, wherein said drive mechanism includes a control unit having a user interface for inputting parameters related to drawing and optionally dispensing of said liquid.

16. The system of claim 15, wherein said control unit includes an optical reader for scanning a drug vial.

17. The system of claim 15, wherein said control unit includes wireless communication capabilities or RFID.

18. The system of claim 1, wherein a proximal end of said shaft is configured capable of connecting to a spring driven mechanism.

19. The system of claim 1, further comprising spring driven mechanism connectable to a proximal end of said shaft of said plunger and said housing, said spring driven mechanism is capable of applying said force to said top of said shaft of said plunger.

20. The system of claim 19, wherein said spring driven mechanism drives said shaft for delivering a liquid from said chamber.

21. The system of claim 20, wherein a tension of a spring of said spring driven mechanism is user adjustable.

22. The system of claim 21, wherein connection of said spring driven mechanism to said shaft and said housing prevents said drive mechanism from moving said plunger.

14. (canceled)

23. A system for medicament preparation and delivery comprising:

(a) a housing including a chamber for containing a liquid; and

(b) a plunger movable within said chamber for drawing and dispensing liquid, said plunger including a spiral groove for engaging a drive gear of a drive mechanism mounted against a side of said plunger is connected at the to of the plunger, said drive gear being rotatable via said drive mechanism to rotatably slide said plunger within said chamber to increase or decrease a volume thereof; and

(c) a toggle for disengaging said drive gear from said spiral groove thereby enabling said plunger to slide within said chamber without rotating.

24. The system of claim 23, wherein said housing and said plunger are configured for enabling a top of said shaft of said plunger to interface with a manually operable plunger driver.
