Abstract
A valved needle assembly including a needle hub provided to a proximal end side of a hollow needle, and a valve member incorporated therein for blocking communication with the hollow needle. A protrusion protrudes from a distal end side toward a proximal end side inside the needle hub and the valve member blocks the proximal end side of the protrusion inside the needle hub. A central valve part of the valve member having a slit moves toward the protrusion such that the slit is opened and placed in communication by the protrusion. The central valve part includes a distal end tubular part and a proximal end tubular part extending from its outer circumferential portion toward the distal end side and the proximal end side respectively.
