Patent ID: 8303571

Claim:
A multiple-line connective device for use in a medication infusing system that includes a plurality of branch tubes having an outside diameter and an inside diameter, the connective device comprising: a body defining a main flow passage from an inlet to an outlet along a longitudinal axis; and a plurality of branches extending from the body, each of the branches defining within it a branch passage in communication with the main flow passage, each of the branch passages having an upstream portion having a uniform first diameter approximately equal to the outside diameter of one of the branch tubes so as to receive one of the branch tubes therein, and a downstream portion having a second diameter smaller than the first diameter and substantially equal to the inside diameter of one of the branch tubes, wherein each of the branch passages is configured to provide a flow path for liquid from one of the branch tubes into the main flow passage, such that a direction of liquid flow through each of the branch passages resolves into a first component that is perpendicular to the longitudinal axis and a second component that extends from the inlet to the outlet parallel to the longitudinal axis.
