2046869 9009776 PCTABS00002 The invention concerns the automated robotic system for dispensing drugs from vials (8) into liquid containing containers (4) such as IV bags or syringes. A system whereby a robot (20) selects a vial (8) and a suitable container (4) and transports them to a processing station (60) together with a needle (53) which may be double-ended. At the processing station (60) the contents of the vial (8) are transferred into the container (4). Some of the contents of the container (4) may be transferred into the vial (8) in order to reconstitute and/or wash out the vial contents and agitation means may be provided for the vial (8). Various additional devices may be provided such as a decapping device (34) for the vials (8), an alcohol swabbing station (90) for swabbing the top of a vial (8) and/or the input port of a IV bag (4) or syringe. Moreover, a label printer (75) may be provided so that the robot (20) may deliver a label with the finally processed IV bag (4) and empty vial (8) to a verification station. When IV bags (4) are used, the invention may feature a conveyor of trays (42) of the bags (4) to a pick-up station of the robot (20). The trays (42) add rigidity of the bags (4) so that they can be handled by the robot (20). To present needles (53) to the robot (20) for the pick-up, needle trays (51) may be used in which needles (53) lie in parallel one to the other in pick-up position. The robot (20), itself, may have gripping fingers (200) having one gripping surface (202) suitable for gripping a vial (8) and another gripping surface (204) suitable for gripping a needle (53) or solution container (4). The containers (4) may be provided with shaped portions suitable for gripping by either of the robot gripping surfaces (202, 204). Vial dispensing means (30) may be a chute (31) or a series of chutes which present vials (8) to specific pick-up locations from which the robot (20) can select a vial (8) in accordance with prescription data.
