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.
