    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 (100) has a fluid delivery compartment (101) containing a first infusion fluid (103), a flexible membrane (104), and an openable bag (150) containing a second infusion fluid (152). An attached gas reaction compartment (121) contains chemical reactants (123, 134) which, when combined, react to evolve gas (122). The gas (122) expands a gas expansion chamber (102) causing the membrane (104) to move into the fluid delivery compartment (101), displacing the first infusion fluid (103). The membrane (104) eventually contacts and compresses the openable bag (150). Pressure from the membrane (104) causes the bag (150) to open and discharge its contents out of the infusion device (100).

    摘要: The present invention relates to apparatus (5) and method for the controlled delivery of fluid. The apparatus (5) comprises chemical reactants (65, 70) which combine to generate gas and create pressure to drive a fluid (20) from a container (17). The reactants (65, 70) and the environment in which the reaction occurs are controlled, thereby causing the fluid (20) to be delivered from the device (5) at a predetermined flow rate.

    摘要: A liquid dispensing device (2) and a method of dispensing liquid are disclosed. The device (2) includes a hollow gas and liquid tight casing (4), a flexible gas and liquid tight membrane (18, 130) having at least one convolution (132) and disposed across the casing interior and dividing the interior into a propellant chamber (36) and a liquid chamber (24), an outlet port (28) from the liquid chamber (24), two mutually reactive chemicals (38, 40) in the propellant chamber (36) but reactive upon contact to form a propellant gas. Upon generation of the gas, the gas expands against the membrane (18, 130), pressurizing the liquid chamber (24) to expel the contained liquid through the outlet port (28). A pressure relief valve (45), suitable for use with the device, allows gas to escape from the device when the gas pressure exceeds a predetermined level.
