Fillable cassette apparatus and method
First Claim
1. A method of mixing a drug for administration in a cassette, comprising:
- providing a cassette including an outer housing, an inner reservoir structure within the outer housing, and a delivery conduit connectable to a patient, wherein the inner reservoir contains a liquid;
establishing fluid communication through a fluid transfer connection separate from the delivery conduit between the reservoir of the cassette and a medicant container containing a drug;
dispensing at least a portion of the liquid from the cassette into the medicant container to reconstitute the drug;
transferring the reconstituted drug into the reservoir; and
disconnecting the fluid transfer connection between the reservoir of the cassette and the medicant container.

Abstract
A cassette is described including a housing, an inner reservoir located within the housing, a valve coupled to the inner reservoir and coupled to the housing, and a delivery conduit coupled to the inner reservoir and emerging from the delivery opening of the cassette. The cassette also includes a dispensing apparatus that defines a passage and has a first activating device that opens the valve of the cassette. The dispensing apparatus also has a second activating member capable of establishing fluid communication with a medicant container. A method of mixing a powdered drug and a liquid includes establishing fluid communication between the reservoir and the medicant container, dispensing at least a portion of the liquid into the medicant container, and transferring the mixed drug into the reservoir. A method of filling a cassette includes the steps of introducing the drug into the cassette, closing a first access port, evacuating the inner reservoir through a second access port, and introducing the drug to fill the cassette through the first access port.

14. A method of mixing a drug for administration in a cassette, comprising:
-
providing a cassette including an outer housing, an inner reservoir containing a liquid, and a delivery conduit connectable to a patient;
establishing fluid communication through a fluid transfer connection separate from the delivery conduit between the reservoir of the cassette and a medicant container containing a drug;
dispensing at least a portion of the liquid from the cassette into the medicant container to reconstitute the drug;
transferring the reconstituted drug into the cassette;
connecting the delivery conduit to the fluid transfer connection so the inner reservoir and delivery conduit define a closed system; and
activating a pump mechanism on a portion of the delivery conduit to circulate the reconstituted drug within the closed system of the inner reservoir, whereby the reconstituted drug is further mixed.
