Abstract
A fluid preservation system for use with a container containing both fluid and gas where there exists a transition between the fluid and the gas and where the container has an opening with a first inside diameter and a first inner surface and a body with a second inside diameter and a second inner surface. The fluid preservation system comprises an elongated member with a proximal end and a distal end, an expandable sealing member near the distal end of the elongated member, where the expandable sealing member has an expanded state and a compressed state. Means to change the expanded sealing member between the expanded state and the compressed state is located near the proximal end of the elongated member. The expandable sealing member in the expanded state is in contract with the second inner surface of the container near the transition between the fluid and the gas. The expandable sealing member in the compressed state is able to pass through the first inside diameter of the opening of the container. The means to change the state of the expandable sealing member remains outside of the container and the expandable sealing member in the expanded state displaces less than substantially all of the gas in the container.
