Medical connector

摘要

A medical connector providing connection between medical devices comprising a female end connectable with a male end of a first medical device, a generally circular covering portion attached to the female end that is substantially wider than the transverse cross-section of the female end, a second end configured to connect with a second medical device, a housing extending between the female end and the second end comprising a region adjacent the covering portion that is wider than an outer diameter of the covering portion. In a first stage, the female end is configured to remain stationary with respect to the housing while the male end of the first medical device is rotated onto the female end. In a second stage, the female end is configured to rotate with respect to the housing to inhibit disconnection of the male end of the first medical device.

1. A medical connector configured to provide a permanent connection between medical devices, the medical connector comprising: a female end configured to receive a male end of a first medical device; a generally circular covering portion attached to the female end that is substantially wider than the transverse cross-section of the female end; a second end configured to connect with a second medical device; a housing extending between the female end and the second end, the housing comprising a region adjacent the covering portion that is wider than an outer diameter of the covering portion; a resilient member positioned at least partially within the housing; and an axially moveable valve member; wherein: in a first stage, the female end is configured to remain stationary with respect to the housing while the male end of the first medical device is rotated onto the female end, in that the torque required to rotate the female end with respect to the housing is greater than the torque required to rotate the male end of the first medical device onto female end; in a second stage, after the male end of the first medical device is rotated onto the female end, the female end is configured to rotate with respect to the housing to inhibit disconnection of the male end of the first medical device from the female end of the medical connector; and the medical connector is configured to selectively seal fluid flow from the second end after the medical connector is disconnected from the second medical device.
