Abstract

A drug handling apparatus and method are disclosed. A delivery receptacle, such as a syringe, is provided with a first substance, such as a liquid diluent, either stored in the delivery receptacle or provided from a separate storage receptacle, and the first substance in the delivery receptacle is transferred to a storage receptacle provided with a second substance, such as a drug in solid form, with the transfer being accomplished by moving an actuator, such as the piston within a syringe, in a first direction to create a positive flow of the first substance from the delivery receptacle through a vented transfer unit to the storage receptacle where the substances are mixed to thereby, for example, reconstitute the drug. By then moving the actuator in a second direction, such as by movment of the syringe piston in the opposite axial direction, the mixture is then withdrawn from the storage receptacle and transferred through the vented transfer unit to the delivery receptacle. After removal of the storage receptacle and transfer unit from the delivery receptacle, the mixture can then be discharged from the delivery receptacle to a patient connected therewith by again actuating the actuator in the first direction. Packaging for the delivery and storage receptacles is provided with the receptacles being stored in spaced and sealed relationship until needed.
