AUTOMATED DRUG PREPARATION APPARATUS INCLUDING AUTOMATED DRUG RECONSTITUTION
First Claim
1. A method of preparing a diluted dosage of medication with an automated drug preparation system including the steps of:
- reconstituting medication in a first vial, in an automated manner, to produce reconstituted medication have a first concentration which is greater than an inputted target concentration of the dosage of medication;
loading a syringe onto a device that controllably delivers the loaded syringe from one station to another station;
fluidly connecting the syringe to a source of diluent;
extending a plunger of the syringe a predetermined distance to draw a first volume of the diluent into the syringe;
advancing the partially filled syringe to another station where a predetermined amount of the reconstituted medication is delivered to the partially filled syringe to produce the dosage of medication that has a concentration at least about equal to the inputted target concentration, wherein the reconstituted medication is delivered to the partially filled syringe in a manner different than drawing fluid by extension of the syringe plunger.

Abstract
An automated medication preparation system for preparing a prescribed dosage of medication in a drug delivery device includes a plurality of stations for receiving, handling and processing the drug delivery device so that the prescribed dosage of medication is delivered to the drug delivery device and a transporting device that receives and holds more than one drug delivery device and moves the drug delivery devices in a controlled manner from one station to another station. The system is configured so that two or more separate drug delivery devices can be acted upon at the same time.

26. An automated drug delivery system configured to perform reconstitution of a drug and preparation of a prescribed dosage of medication and delivery to a drug delivery device comprising:
-
an input for entering a drug order;
a first station that holds a plurality of drug vials, each drug vial containing a solid medication and having an identifier that uniquely identifies the drug vial;
a reader that reads the drug vial identifier and transmits read information to a controller that compares the read identifier with the inputted drug order to confirm whether at least drug identifying information of the inputted drug order matches the read identifier and if so, the drug vial is approved for advancement to a second station; and
an automated drug reconstitution device that is located at the second station and includes a source of diluent and a controllable cannula that is selectively in communication with the source of diluent, the drug reconstitution device operating in first, second and third modes, the first mode being an injection mode where a predetermined amount of diluent is injected through a main conduit into the drug vial for wetting and causing the solid medication to go into solution to form reconstituted medication by agitating the solution, the second mode being an aspiration mode for aspirating a predetermined amount of the reconstituted medication into the main conduit where it is held, the third mode being an injection mode where the predetermined amount of aspirated reconstituted medication, which represents the prescribed dosage of medication, is injected through the main conduit into the drug delivery device. - View Dependent Claims (27, 28, 29, 30, 31, 32)

33. An automated drug delivery system configured to perform reconstitution of a drug and preparation of a prescribed dosage of medication and delivery to a drug delivery device comprising:
-
an input for entering a drug order;
a reconstitution database that includes detailed instructions on how to reconstitute the drug that is uniquely identified by the drug order;
a first station that holds a plurality of drug vials, each drug vial containing a solid medication and having an identifier that uniquely identifies the drug vial;
a reader that reads the drug vial identifier and transmits read information to a controller that compares the read identifier with the inputted drug order to confirm whether at least drug identifying information of the inputted drug order matches the read identifier and if so, the drug vial is approved for advancement to a second station; and
an automated drug reconstitution device that is located at the second station and includes a controller that is in communication with the reconstitution database so that once the drug order is inputted and the reconstitution instructions are retrieved, the controller instructs the automated drug reconstitution device so that the prescribed dosage of medication is prepared and delivered to the drug delivery device in an automated manner and the drug delivery device itself is identified with a unique identifier which is linked to the drug order for the prescribed dosage of medication contained in the drug delivery device and permits tracking of the drug delivery device from station to station. - View Dependent Claims (34, 35, 36)

37. A method of preparing a diluted dosage of medication with an automated drug preparation system including the steps of:
-
reconstituting medication in a first vial, in an automated manner, to produce reconstituted medication;
loading a syringe onto a device that controllably delivers the loaded syringe from one station to another station;
extending a plunger of the syringe a predetermined distance to create a first volume in the syringe; and
advancing the partially filled syringe to where a predetermined amount of the reconstituted medication, that is less than the first volume, is delivered into the syringe to produce the dosage of medication. - View Dependent Claims (38)
