Y-connector for medical lines

A Y-connector for medical lines, comprising:

• a tubular body having a first inlet coaxial with a longitudinal axis of the tubular body and containing a valve device formed by a hollow elastic element sealingly closing said first inlet in an openable manner, an outlet, and a second inlet arranged obliquely to, and extending outwardly from, a first inner surface of the tubular body and communicating therewith between said first inlet and the outlet;
• the tubular body formed with an inner septum for deviating a flow coming from the second inlet towards the elastic element prior to directing the flow to the outlet, said inner septum extending axially into an interior of the elastic element and having a radial end portion connected to the tubular body in proximity of said second inlet so as to define a first chamber open towards the elastic element and closed on an opposite side of the first chamber toward the outlet, and a second chamber open towards the elastic element and towards the outlet;
• said first chamber radially bounded by a first side of said inner septum and said first inner surface of the tubular body, said second chamber bounded by a second side of said inner septum and a second inner surface of the tubular body;
• and
• wherein a longitudinal axis of said inner septum is offset relative to the longitudinal axis of the tubular body such that the first chamber has a radial size greater than that of the second chamber;
• wherein said inner septum is provided with a concave surface facing towards said first chamber.
