TURBULENCE MINIMIZING DEVICE FOR MULTI-LUMEN FLUID INFUSING SYSTEMS AND METHOD FOR MINIMIZING TURBULENCE IN SUCH SYSTEMS

摘要

A fluid turbulence minimizing device includes a connection portion defining a connection cavity shaped to receive a tertiary fluid-supply conduit including a primary fluid-supply lumen and two secondary fluid-supply lumens and an intermixing portion having a longitudinal flow axis and defining an intermixing cavity that has an input orifice fluidically communicating with the connection cavity and a given area, an exit orifice having an area less than the given area, an inner surface having an upstream side adjacent the connection portion, a downstream side at a distance from the connection portion, and a cross-sectional area decreasing from the input orifice to the exit orifice to convey fluid supplied from the conduit to the connection cavity through the intermixing cavity and out the exit orifice, and guide fins inwardly projecting from the inner surface of the intermixing portion toward the longitudinal flow axis and having a longitudinal extent aligned substantially parallel with the longitudinal flow axis.
