    摘要： A liquid dispensing device and the method of dispensing liquid are disclosed. The device includes a hollow gas- and liquid-tight casing, a flexible gas- and liquid-tight membrane having multiple convolutions disposed across the casing interior and dividing the interior into a propellant chamber and a liquid chamber, an outlet port from the liquid chamber. A pressure relief valve, suitable for use with the device, allows gas to escape from the device when the gas pressure exceeds a predetermined level.

    摘要： A liquid dispensing device and the method of dispensing liquid are disclosed. The device is uniquely suited to meet the requirements of hospitals and other institutions for long shelf life in inert condition and ready activation when needed. The device includes a hollow gas- and liquid-tight casing (preferably spherical or cylindrical), a flexible gas- and liquid-tight membrane disposed entirely across the casing interior dividing the interior into a propellant chamber and a liquid chamber; an outlet port from the liquid chamber; two mutually reactive chemicals in the propellant chamber but separated by a barrier; and a member to breach the barrier and permit the chemicals to come into contact; the two chemicals being reactive upon contact to form a propellant gas. The propellant gas thereupon expands against the membrane, moves the membrane to enlarge the propellant chamber, decrease the liquid chamber, and expel the contained liquid from the liquid chamber through the outlet port. The barrier may be breached in any convenient manner, as by breaking a frangible barrier or perforating a perforable one. Preferably at least one of the chemicals is in liquid form, and one is a Group I or II metal carbonate or bicarbonate while the other is an acid, acid anhydride or acid salt; the most preferred combination is sodium carbonate and citric acid.

    摘要： A device is disclosed which provides direct and effective incorporation of material (such as medicine) from a separate container into the contents of a liquid dispensing device. The device has a hollow sleeve extending outwardly, an openable closure, a securing member which engages a mating member on the container, and a conduit (such as a needle) to provide fluid communication between the device and the container, with the fluid communication occurring upon attachment of the container to the device. The device can also provide for attaching the separate container to the dispensing device but without initially establishing liquid communication between the two.

    摘要： We disclose apparatus and methods for delivering for patient infusion or other use two or more fluids either sequentially or simultaneously. The apparatus has a fluid delivery compartment containing a first infusion fluid, a flexible membrane, and an openable bag containing a second infusion fluid. An attached gas reaction compartment contains chemical reactants which, when combined, react to evolve gas. The gas expands a gas expansion chamber causing the membrane to move into the fluid delivery compartment, displacing the first infusion fluid. The membrane eventually contacts and compresses the openable bag. Pressure from the membrane causes the bag to open and discharge its contents out of the infusion device.
