Expandable fluid preservation system and method for use

摘要

A fluid preservation device, for preserving a liquid within a container, which includes an elongated member with a proximal end and a distal end and an inner shaft and an outer shaft. The outer shaft and inner shaft are attached to an expandable sealing member. The expandable sealing member has an expanded state and a collapsed state and a state change mechanism attached to the proximal end of the elongated member to change the state of the expandable sealing member between the expanded state and the collapsed state. When the expandable sealing member is in the collapsed state, it can pass through an opening of a container and when the expandable sealing member is in the expanded state it is big enough to contact the inner surface of the container near the surface of the liquid.

1. A fluid preservation device for preserving a liquid within a container, the fluid preservation device comprising:
an elongated member with a proximal end and a distal end; where the elongated member comprises an inner shaft and an outer shaft; where the outer shaft is attached to an expandable sealing member; where the inner shaft is attached to the expandable sealing member; where the fluid preservation device includes an end piece at its distal end; where the expandable sealing member has an expanded state and a collapsed state; a state change mechanism attached to the proximal end of the inner shaft and the outer shaft of the elongated member to change the state of the expandable sealing member between the expanded state and the collapsed state; where the inner shaft is configured to move with respect to the outer shaft during the change of state; where the expandable sealing member in the collapsed state is sized to pass through an opening of a container; and where the expandable sealing member in the expanded state is sized to contact an inner surface of the container near a surface of the liquid.
