Medical connector
First Claim
1. A medical fluid connector configured to inhibit disconnection, comprising:
- a proximal region comprising an end cap portion and a distally extending plunger, an inside surface of the distally extending plunger configured to be in contact with medical fluid passing through the connector when in use;
an intermediate portion comprising a proximally extending wall, an inside surface of the proximally extending wall configured to be in contact with medical fluid passing through the connector;
an o-ring contacting both a portion of the distally extending plunger and a portion of the proximally extending wall in a region where the distally extending plunger and the proximally extending wall overlap; and
wherein the medical fluid connector comprises a first stage in which the plunger and the intermediate portion are not capable of rotating with respect to each other, and the medical fluid connector comprises a second stage in which the plunger and the intermediate portion are capable of rotating with respect to each other, the transition from the first stage to the second stage being configured to be actuated by advancement of a medical implement at the proximal region of the medical fluid connector; and
wherein rotation between the plunger and the intermediate portion is configured to inhibit disconnection of the medical fluid connector from the medical implement.

Abstract
Some embodiments comprise a connector including a rigid housing having a first end and a second end. A second member can be positioned at a second end portion of the housing and be engageable with a second device. The second member can have a body portion having a first body portion, a second body portion, and a flow lumen extending axially through the body portion, an annular covering portion extending in a radial direction away from the body portion, a receiving portion extending away from the covering portion in an axial direction, and at least one protrusion extending radially away from an outside surface of the body portion. In some embodiments, the second member can be supported by the housing such that, in an assembled state, the first body portion is positioned within the housing and such that the annular covering portion and the second body portion are positioned outside the housing.
