  • Packaged container containing ocular perfusion/washing solution and process for producing the same
    Patent number: 7347324
    Abstract: The present invention provides an improved packaged container containing an ocular perfusion/washing solution, the solution being securely prevented from generating gas bubbles that impede operation when used as an ocular perfusion/washing solution in cataract surgery, etc., and a process for producing the same. In the packaged solution container, the ocular perfusion/washing solution (1) is contained in a gas-permeable plastic container (2) which is packaged in a gas-impermeable packaging member (3). Between the container (2) and the packaging member (3), there is a space (4) which has a volume at least 4 times that of the total of the volume of the headspace of the container and the volume of dissolved gas. This space (4) holds a mixed gas atmosphere comprising carbon dioxide and helium and/or neon.
