摘要： Valve devices are provided for draining fluids from and/or infusing fluids into a patient's body that include a housing including first, second, and third connectors, a primary fluid path communicating between the first and second connectors, and a secondary fluid path communicating from the primary fluid path to the third connector. First and second valve members are movable within the housing between first positions wherein the valve members do not obstruct the primary fluid path and second positions wherein the primary fluid path is at least partially closed. The third connector may be configured to prevent fluid flow therethrough unless a mating connector is fully coupled thereto. The valve members may be selectively closed to isolate portions of the flow path to allow a source of vacuum or fluid coupled to the third connector to aspirate or infuse fluid along portions of the primary fluid path.
