CONNECTOR AND CONNECTOR ASSEMBLY
First Claim
1. A connector, comprising:
- an outer tube;
a hub having a main body portion disposed at a proximal end portion of the outer tube and 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 projection portion configured to screw with the screw threaded portion;
a weakly connecting portion connecting the outer tube and the hub to each other and being capable of being broken; and
separation preventing means for preventing the main body portion from being separated from the outer tube after the weakly connecting portion is broken;
wherein the weakly connecting portion is configured such that the weakly connecting portion is not broken by rotational torque applied to the hub when the medical device is rotated in a direction with respect to the hub to screw the screw threaded portion with the projection portion but is broken when, after the screwing of the screw threaded portion with the projection portion is completed, the medical device is rotated in a same direction as the direction upon the screwing of the screw threaded portion with the projection portion to apply rotational torque to the hub; and
wherein the hub is permitted to rotate around an axis of the outer tube with respect to the outer tube after the weakly connecting portion is broken.

Abstract
A first connector has a first connector main body configured from an outer tube having a cylindrical shape, an inner tube having a cylindrical shape and a hub, 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 in a direction toward the distal end thereof, and a clamping member disposed on the outer tube. The hub is disposed at a proximal end portion of the outer tube. The hub is disposed such that, although the hub is initially connected to the outer tube by a breakable welded portion, when the welded portion is broken, the hub is permitted to rotate around an axis of the outer tube with respect to the outer tube.
