摘要

PROBLEM TO BE SOLVED: To provide a needleless connector providing both a fluid path and a ventilation path, each path having a self-sealing function, and by connecting to a female connector, both paths are opened and separated from the female connector. To provide a needleless connector by which both paths are closed. According to the present invention, a main body having a fluid path, a ventilation path and a male fitting, and a valve arranged in the male fitting, the first configuration in which the fluid path is blocked, and a fluid. A valve configured to move between a second configuration in which the path is open and a seal tip fixedly placed around the valve to form a sliding seal between the valve and the male fitting.
