The typical method for reconstitution of lyophilized medication requires the puncture of a rubber vial stoppers by a needle filled with diluents. The medication in the vial is mixed and the needle is withdrawn and then used to inject into the patient. The puncture of the rubber septum can dull the tip of the needle prior to injecting into patient and provides unnecessary opportunity for a needlestick accident. Newer technologies do not require a needle.
Scenes like this one create unnecessary exposure to needlesticks. Technology exists to transfer medication from vials to syringe or from vial to vial without ever using a needle!
