<P>PROBLEM TO BE SOLVED: To provide a preparing and delivering system for intravenous drugs which system may return a powder drug to liquid. <P>SOLUTION: The system comprises a liquid inlet 22 for connection to a liquid supply, vials 11a-11c, and a liquid outlet 23 for delivery an intravenous drug in a mixed liquid form to a patient. The system may include a delivery chamber 27, a mixing chamber 28, and valve mechanisms 31a-31i. The valve mechanisms may be actuated to control flow between the liquid outlet 23, the delivery chamber 27, the mixing chamber 28, the vials 11a-11c, and the liquid inlet 22. The system changes volumes of the delivery chamber 27 and the mixing chamber 28 and actuates the valve mechanisms 31a-31i to guide the liquid from the liquid inlet 22 to the vials 11a-11c to liquefy or dilute the drug to deliver the drug to the patient. The liquid inlet 22, the vials 11a-11c, the delivery chamber 27, the mixing chamber 28, the liquid outlet 23, and the valve mechanisms 31a-31i are placed in a disposable cassette storable in a controller. <P>COPYRIGHT: (C)2009,JPO&INPIT |
