Abstract: In one exemplary embodiment, an automated means for withdrawing a syringe plunger a method for just-in-time extension of the plunger to permit filling the syringe with a prescribed dose of medication are provided. The method includes the steps of: (1) inputting a desired volume of the prescribed dose of medication; (2) inputting syringe identifying information; (3) calculating a distance that the plunger is to be extended based on the inputted desired volume and syringe identifying information; (4) calculating drive parameters for a controllable drive that causes extension of the plunger when actuated and ensures that the plunger is extended the desired distance; and (5) controlling the drive in view of the calculated drive parameters to cause the plunger to be extended the desired distance.

Abstract: In one exemplary embodiment, an automated syringe preparation mechanism for an automated medication preparation system is provided and the mechanism includes (1) a first automated gripping mechanism having a pair of adjustable gripper arms for removing a tip cap from a barrel of one syringe and placing the removed tip cap at a first location and (2) a second automated gripping mechanism having a pair of adjustable gripper arms for replacing the removed tip cap on the syringe barrel after the medication is injected therein.

Abstract: A computer-implemented method and system for cleaning a contaminated cannula so that it may be reused includes moving the contaminated cannula from a drug reconstitution station where the cannula is used to prepare a drug solution into a first rinsing station where the cannula is cleaned. A database is referred to to determine what drug solution the cannula has been contaminated with, and to determine a first amount of cleaning fluid that needs to be passed internally through the cannula, and a second amount of cleaning fluid that needs to be passed externally about the cannula so that there is effectively no contaminant remaining inside and outside of the cannula. The first amount of cleaning fluid is passed internally through the cannula. The second amount of cleaning fluid is passed externally about the cannula. After the cannula is cleaned, the cannula is moved to the drug reconstitution station to prepare another drug solution.

Abstract: A method and software interface enables serial data streams to be trapped, parsed, tested for suitability for automated handling by a medication preparation system. Only those portions of the serial data stream that are not suitable for such handling are released for printing and manual handling. A serial data interface includes a listener software module (“LSM”) that receives serial data streams and a parser software module (“PSM”) communicatively connectable to the LSM that processes the serial data streams received from the LSM. A set of configuration rules accessible by the PSM defines the manner of processing by the PSM on the serial data streams. A data structure results that enables data handling by an automated medication preparation system.
