Patent ID: 8731639

Claim:
An accommodating connector configured to reduce blood clotting in a fluid flow between a medical device and a source of fluid, the accommodating connector comprising: an outer connecting structure configured to removably interlock with an outer portion of a standard medical connector to form an interior volume; a tube extending through the outer connecting structure, an interior of the tube forming a fluid path and terminating at a port, the tube configured to extend from the accommodating connector and protrude into the interior volume in a direction aligned with the fluid path such that the fluid path passes through the interior volume, out of the port and continues in the same direction into a lumen of the standard medical connector, the interior of the tube aligned with the lumen and having a diameter that is similar to a diameter of the lumen, thereby minimizing change in the cross-sectional area of the flow path from the accommodating connector into the standard medical connector to improve fluid flow; a lubricious coating configured to reduce blood clotting, the coating applied to at least a portion of the fluid path within the tube; and a sealing mass on the tube such that it encircles the tube, the sealing mass positioned at or near an interface between the port and the standard medical connector and that has a shape configured to correspond with a shape of the standard medical connector when the standard medical is removably interlocked with the accommodating connector such that the sealing mass prevents the fluid from leaking out of the port and into the interior volume instead of proceeding into the lumen of the standard medical connector, the sealing mass configured to provide a seal only when the outer connecting structure of the accommodating connector is interlocked with the standard medical connector such that the tube protrudes into the interior space, the sealing mass thereby positioned and shaped to function together with the lubricious coating, the tube, and the tube's alignment with and similar diameter to the lumen of the medical connector to reduce blood clotting and confine the fluid flow to the fluid path while inhibiting leakage into and clotting within the interior volume outside the fluid path.
