CONNECTOR AND CONNECTOR ASSEMBLY
First Claim
1. A connector, comprising:
- an outer tube;
a hub disposed at a proximal end portion of the outer tube for rotation around an axis of the outer tube with respect to the outer tube, wherein the hub includes a main body portion inserted in the outer tube, a connecting portion having a proximal end side to which a medical device having a screw threaded portion is to be connected, and a projecting portion for being screwed with the screw threaded portion;
separation preventing means for preventing separation of the hub from the outer tube; and
rotation blocking means having a rotation blocking function for blocking the rotation of the hub in at least one of a forward direction and a backward direction;
wherein the rotation blocking means includes a rotation blocking member disposed for separation on the outer tube and having a first engaging portion, and a second engaging portion provided on the hub and engageable with the first engaging portion in a state in which the rotation blocking member is disposed on the outer tube, andwherein the rotation blocking function of the rotation blocking means is rendered effective when the first engaging portion and the second engaging portion are engaged with each other.

Abstract
A first connector includes a first connector main body configured from an outer tube of cylindrical shape, an inner tube of cylindrical shape, a hub disposed at a proximal end portion of the outer tube, and a clip disposed so as to be removable at the proximal end portion of the outer tube, a hollow needle supported on the hub, a first sealing member supported on the inner tube, a coil spring serving as puncturing portion biasing means for biasing the first sealing member toward the distal direction, and a clamping member disposed upon the outer tube. In a state in which the clip is mounted to the proximal end portion of the outer tube, a protrusion of the clip engages with a protrusion of the hub, and thereby rotation of the hub is prevented. If the clip is removed, the hub becomes rotatable with respect to the outer tube.
