  • Microflow restrictor assembly and methods of making the same
    Patent number: 11426511
    Abstract: A medical fluid microflow assembly having an assembly fluid inlet and an assembly fluid outlet, and a mandrel having a curved exterior surface, the mandrel being positioned within an cavity of a housing so that the exterior surface of the mandrel is substantially parallel to an interior surface of the cavity, and at least one protrusion positioned helically around and extending from the interior surface of the cavity, each protrusion abutting the exterior surface of the mandrel to form a sealed fluid channel which has a channel inlet positioned proximate to the assembly fluid inlet and a channel outlet positioned proximate to the assembly fluid outlet, the exterior surface of the mandrel and the interior surface of the cavity having a minimal or neutral triboelectric value with respect to a fluid.
