6. A method for transferring solid medications in a vial into an infuser container having a fill port, which comprises the steps of:
-
connecting the vial to one port of a three-way valve;
connecting a syringe containing an effective amount of solvent for dissolving the solid medication to a second port of the three-way valve;
connecting the infuser to the third port of the three-way valve;
transferring the solvent from the syringe to the vial through a pathway in the three-way valve connecting the syringe with the vial, thereby forming a solution;
withdrawing the solution from the vial into the syringe through the pathway in the three-way valve connecting the syringe with the vial; and
transferring the solution from the syringe to the infuser container through a pathway in the three-way valve connecting the syringe with the fill port of the infuser container. - View Dependent Claims (7, 8, 9)
