Method and system for cleaning and reusing a cannula

A system for cleaning a reusable cannula comprising:

• a drug reconstitution station operative to prepare a first drug solution by use of a cannula thereby contaminating the cannula;
• a cannula rinsing station operative to clean the cannula internally and externally with a cleaning fluid so that there is effectively no contaminant remaining inside and outside of the cannula;
• the cannula being movable between the drug reconstitution station and the cannula rinsing station;
• whereby after the cannula has been cleaned at the cannula rinsing station, the cannula can be reused in the drug reconstitution station to reconstitute a second drug solution that is different than the first drug solution.

A computer-implemented method for cleaning a contaminated cannula so that it may be reused, comprising the steps of:

• moving a particular cannula into a first rinsing station;
• referencing a database to determine what drug solution the cannula has been contaminated with;
• referencing the database to determine a first amount of cleaning fluid that needs to be passed internally through the cannula so that there is effectively no contaminant remaining inside of the cannula;
• referencing the database to determine a power and time setting for an ultrasonic transducer that is placed externally about a fount which receives the cannula;
• passing at least the first amount of cleaning fluid internally through the cannula;
• and
• activating the ultrasonic transducer at the determined power and time setting so that there is effectively no contaminant externally about the cannula.
