  • Patent number: 10525234
    Abstract: A safety needle assembly of an infusion set is disclosed. The needle assembly is configured to prevent fluid/vapor escape therefrom so as to reduce or prevent fluid exposure to a clinician using the needle assembly.

The needle assembly also includes a safety assembly defining a needle hole through which the needle initially extends. The safety assembly is selectively and axially slidable along the needle in order to shield a distal tip of the needle and prevent user contact therewith. A fluid isolation component is included in the safety assembly for isolating fluid escape from the needle. In another embodiment, an interface pad is included on the bottom of the needle assembly and includes an antimicrobial and/or haemostatic agent to protect the needle insertion site.

  • Patent number: 9631285
    Abstract: A process is provided for synthesizing synthesis gas from carbon dioxide obtained from atmospheric air or other available carbon dioxide source and water using a sodium-conducting electrochemical cell. Synthesis gas is also produced by the coelectrolysis of carbon dioxide and steam in a solid oxide fuel cell or solid oxide electrolytic cell. The synthesis gas produced may then be further processed and eventually converted into a liquid fuel suitable for transportation or other applications.

  • Patent number: 9017437
    Abstract: A method of forming a synthesis gas utilizing a reformer is disclosed. The method utilizes a reformer that includes a plasma zone to receive a pre-heated mixture of reactants and ionize the reactants by applying an electrical potential thereto. A first thermally conductive surface surrounds the plasma zone and is configured to transfer heat from an external heat source into the plasma zone. The reformer further includes a reaction zone to chemically transform the ionized reactants into synthesis gas comprising hydrogen and carbon monoxide. A second thermally conductive surface surrounds the reaction zone and is configured to transfer heat from the external heat source into the reaction zone. The first thermally conductive surface and second thermally conductive surface are both directly exposed to the external heat source. A corresponding apparatus and system are also disclosed herein.
