System for monitoring production of prefilled syringes
First Claim
1. A method of making prefilled syringes, the method comprising the steps of:
- displacing a succession of syringes along a conveyor path from a supply station successively through a marking station, a filling station, and to a downstream packing station;
permanently marking the syringes in the marking station with machine-readable data identifying the medicament to be put in the empty syringe at the filling station;
scanning the syringes downstream of the marking station and upstream of the filling station and removing from the conveyor path any syringe whose data is not readable;
filling each of the syringes with a predetermined dose of a medicament in the filling station; and
scanning the syringes downstream of the filling station and upstream of the packing station and removing from the conveyor path any syringe whose data does not correspond to the medicament filled into the syringe at the filling station.

Abstract
Prefilled syringes are made by displacing a succession of syringes along a conveyor path from a supply station successively through a marking station, a filling station, and to a downstream packing station. Each of the syringes is filled with a predetermined dose of a medicament in the filling station. The syringes are marked in the marking station with machine-readable data identifying the medicament to be put in the empty syringe at the filling station. The syringes are scanned downstream of the marking station and any syringe whose data is not readable is then removed from the conveyor path, as is any syringe whose data does not correspond to the medicament filled into the syringe at the filling station.

10. An apparatus for making prefilled syringes, the apparatus comprising:
-
means for displacing a succession of syringes along a conveyor path from a supply station successively through a marking station, a filling station, and to a downstream packing station; means at the filling station for filling each of the syringes with a predetermined dose of a medicament in the filling station; means along the path at the marking station upstream of the filling station for permanently marking the syringes with machine-readable data identifying the medicament to be put in the empty syringe at the filling station; means along the path downstream of the marking station and upstream of the filling station for scanning the syringes and removing from the conveyor path any syringe whose data is not readable; and means along the path downstream of the filling station and upstream of the packing station for removing from the conveyor path any syringe whose data does not correspond to the medicament filled into the syringe at the filling station. - View Dependent Claims (11, 12, 13)
