Abstract
A disposable cassette for mixing an intravenous drug in a vial to a patient includes a liquid inlet for connection to a liquid supply, a first vial spike, a second vial spike and a chamber. The chamber, the first and second vial spikes, and the liquid inlet are in fluid communication with each other. A valve mechanism may be actuated to control flow between the chamber, the vial receptacles and the liquid inlet.
Claims22
A method for preparing an intravenous drug in a vial to a patient, the method comprising:
- providing a disposable cassette having (i) a liquid inlet, (ii) a vial receptacle, and (iii) a chamber;
- attaching a supply of liquid to the liquid inlet;
- attaching the vial containing the drug to the vial receptacle;
- introducing a volume of liquid into the vial;
- and
- causing the liquid to flow between the vial and the chamber.
A disposable cassette for mixing an intravenous drug in a vial to a patient, the cassette comprising:
- a liquid inlet for connection to a liquid supply;
- a first vial spike;
- a second vial spike;
- a chamber;
- the chamber, the first and second vial spikes, and the liquid inlet being in fluid communication with each other;
- and
- a valve mechanism, which may be actuated to control flow between the chamber, the vial receptacles and the liquid inlet.
A disposable cassette comprising:
- a liquid inlet for receiving an IV solution;
- a vial inlet for receiving a medication;
- an outlet;
- and
- an outlet free-flow-prevention valve which, when actuated, is permanently closed to prevent flow through the outlet.
A method of delivering a dose of medication to a patient, the method comprising:
- providing a cassette having a chamber having an inlet leading from a medication supply and an outlet leading to the patient, a manifold providing fluid communication between the medication supply and the chamber, an outlet valve controlling flow out of the chamber, an inlet valve controlling flow between the chamber and the manifold, and an air valve controlling flow of air through the manifold;
- moving a first volume of medication from the supply through the manifold to the chamber;
- delivering the first volume of medication from the chamber to the patient;
- moving a second volume of medication from the supply through the manifold towards the chamber;
- urging air through the manifold to force substantially all the medication from the manifold into the chamber;
- and
- delivering the second volume of medication from the chamber to the patient.
