Apparatus for selectively mixing two components such as a powder and a liquid in a quick and efficient manner. The apparatus includes a compressible chamber with a liquid component therein, the compressible chamber including gas-trapping and reservoir compartments in open communication. Included is an arrangement to access the gas-trapping compartment such that the chamber may be connected to a container having a mixing component such as a powder therein so as to form a selectively opened pathway between the container and the compressible chamber of the apparatus. The apparatus may include the container. After the pathway is opened, the gas-trapping and reservoir compartments are selectively positioned to facilitate proper mixing of the liquid component in the chamber with the component in the container. Also disclosed is a manipulation for separately storing and selectively mixing two components in the apparatus including the container, the manipulation including pathway opening, liquid transfer, liquid exchange and liquid emptying from the container into the chamber.

A method for separately storing and selectively mixing two components in an apparatus, the apparatus including a compressible chamber having a selectively gas-trapping compartment and a reservoir compartment in open communication with the gas-trapping compartment, the compressible chamber further including an internal wall having a closed end and an open end and segregating the gas-trapping and reservoir compartments except for an open flow path between the compartments adjacent the open end, the compressible chamber containing a liquid, first component, the apparatus further including a container containing a second component, at least one of the compressible chamber and the container also containing a gas, the apparatus also including a selectively opened pathway between the container and the gas-trapping compartment, the steps comprising: (a) opening the pathway between the compressible chamber and the container; (b) transferring some of the liquid first component into the container through the pathway after some gas is in the container, said liquid transfer including, (i) manipulating the chamber until the liquid first component is adjacent the chamber access means, (ii) compressing the chamber, thereby urging some liquid from the chamber into contact with the second component in the container, and (iii) stopping said compression before the container is filled with liquid; (c) exchanging some of the liquid in the container with some of the liquid in the chamber by, (i) manipulating the chamber until liquid in the gas-trapping compartment is adjacent the chamber access means and the chamber access means is above the gas-trapping compartment, (ii) compressing the chamber, thereby urging some liquid from the chamber into the container, and (iii) stopping said compression, thereby urging some liquid from the container into the chamber; and (d) emptying the liquid in the container into the chamber, said liquid emptying step including, (i) manipulating the chamber such that at least some of the gas in the reservoir compartment enters the gas-trapping compartment through the flow path, (ii) manipulating the chamber until the gas in the gas-trapping compartment is adjacent the chamber access means and the chamber access means is above the gas-trapping compartment, (iii) compressing the chamber, thereby urging at least some of the gas from the gas-trapping compartment into the container, thus pressurizing the gas, above the liquid in the container, and (iv) stopping said compression of the chamber, the pressurized gas in the container expelling the liquid in the container through the pathway into the chamber.
