Abstract
A fluid-communicating device with valve function comprising a tubular body having an inlet and an outlet, and a blocking body inserted in the tubular body is disclosed. The blocking body comprises a plug portion, and a supporting portion on which a diameter-enlarging portion for enlarging an inner wall of the tubular body is provided. The plug portion of the blocking body is placed in a seal portion of the tubular body to close the tubular body and to prevent the passage of fluid. In use, a tip of a syringe and the like is inserted into the tubular body, so that there is formed a clearance between the outer wall of the plug portion and the inner wall of the seal portion. Fluid passes through the clearance and a fluid passage formed longitudinally on the supporting portion or on an inner wall of the tubular body.
