An apparatus for delivering a gas-supersaturated solution to a delivery site comprising: a hollow, gas-tight vessel; a collapsible container of solution disposed within the vessel so that a space between the container and the vessel is provided; a tubular member sealingly inserted into the vessel and the container, the tubular member being in communication with a supply of gas under pressure for driving the gas into the solution via the tubular member, thereby preparing gas-supersaturated solution within the container; an inlet port provided in the vessel in communication with the space and the supply of gas for pressurizing the space; an adjustable container exit valve in communication with the container, the container exit valve controlling the flow of undissolved gas from the container; an adjustable space exit valve in communication with the vessel, the space exit valve capable of controlling the flow of gas from the space so that gas leaves the space at a higher rate than that at which gas is introduced into the solution; a fluid control means having a gas-opened state which permits the gas to flow from the supply into the tubular member and a gas-closed state which precludes the gas from flowing from the supply to the tubular member by the fluid control means and the gas-supersaturated solution may flow from the tubular member to the delivery site without bubble formation.
