    摘要： Methods and systems for measuring the volume of a liquid in a subject chamber, such as the mixing chamber in a system for mixing and delivering drugs, for example. A volume of a control gas in communication with the subject chamber is isolated, such that the total volume of the control gas and the liquid is held constant, and the initial pressure of the control gas is measured. Then, a known volume of liquid is moved into or out of the subject chamber. This known volume may be exchanged between the subject chamber and a measurement chamber, in order to determine this volume. The final pressure of the control gas is also measured after the reference volume has been removed from or added to the chamber and while the volume of control gas remains otherwise isolated. The volume of liquid in the chamber may then be measured based on (a) the initial pressure, (b) the final pressure, (c) the reference volume and (d) the volume of gas in the subject chamber when the subject chamber is empty of liquid.

    摘要： A bedside-pharmacy system for the preparation and delivery of intravenous drugs. The system includes a liquid inlet for connection to a liquid supply, vial receptacles, and a liquid outlet for providing the intravenous drug in mixed, liquid form to the patient. The system may include a chamber having a variable volume, and a valve mechanism, which may be actuated to control flow between the liquid outlet, the variable-volume chamber, the vial receptacles and the liquid inlet. The system induces change in the volume of the variable-volume chamber and actuates the valve mechanism, so as to introduce liquid from the liquid inlet into the vials and reconstitute or dilute the drugs and so as to deliver the drugs to the patient. In a preferred embodiment, the liquid inlet, the vial receptacles, the variable-volume chamber, the liquid outlet and the valve mechanism (in other words, all components that come into contact with the liquid) are located in a disposable cassette, which may be received in a control unit. The system may include means for changing the chamber volume and actuating the valves so as to move the liquid repeatedly between a vial and the chamber. After the drug has been reconstituted, the system may cause the drug to be further diluted by providing an additional volume of liquid to be mixed with the drug. The system may further include a second chamber for delivery of the drug to the patient in precise quantities.

    摘要： A liquid ring pump includes an external housing enclosing a volume including a lower fluid reservoir. A rotatable inner housing is within the volume of the external housing, the inner housing enclosing an inner fluid chamber. A pitot tube provides fluid communication between the lower fluid reservoir and the inner fluid chamber. The housings and pitot tube are adapted so that when the inner housing rotates, fluid flows from the lower fluid reservoir through the pitot tube into the inner fluid chamber to develop a liquid ring within the inner fluid chamber such that an inner radial wall of the liquid ring is just radially outward from a point where the pitot tube enters the inner fluid chamber.
