Pump system and method for transferring hyperpolarized gases

摘要

A pumping system for hyperpolarized gases employs a reversible fluid flow against a deflectable gas transport bladder. Inflation and deflation of the gas transport bladder is operably associated with valves for directing the flow of the hyperpolarized gas. A second gas transport bladder may be operably associated with additional valving so as to provide more continuous hyperpolarized gas flow. The first and second gas transport bladders may be arranged in-line with a reversible pumping mechanism.
