Vascular access device septum venting
First Claim
Patent Images
1. A medical connector device, comprising:
- a body, having an interior chamber and a first male connector end and a second female connector end, and a septum disposed within the interior chamber which is selectively actuated;
a gas permeable vent capable of venting a gas from the interior chamber of the body to the exterior of the body; and
a movable vent plug disposed within the gas permeable vent and being selectively movable to close the gas permeable vent to gas venting upon contact with the septum.

Abstract
A vascular access device may include a septum and a gas permeable vent in communication with at least a portion of the septum. The vent may be capable of venting gas from an extravascular system to which the vascular access device is capable of attaching. A method of venting a medical device may include providing a vascular access device having a septum and forming part of an extravascular system, providing a gas permeable vent in communication with at least a portion of the septum, and venting gas from the extravascular system through the gas permeable vent of the device.

12. A method of venting a medical device, comprising:
-
providing a vascular access device comprising a body, having an interior chamber and a first male connector end and a second female connector end, and a septum disposed within the interior chamber which is selectively actuated; providing a gas permeable vent capable of venting a gas from the interior chamber of the body to the exterior of the body; providing a movable vent plug at least partially within the gas permeable vent; venting gas through the gas permeable vent of the vascular access device; and selectively closing the vent by activating the septum, such that contact between the septum and the vent plug closes the vent.

13. A medical connector device, comprising:
-
a body, having an interior chamber and a first male connector end and a second female connector end, and a septum disposed within the interior chamber which is selectively actuated; a vent forming a fluid connection between the interior chamber and the exterior of the body; and a movable vent plug disposed within the vent, the movable vent plug having a solid portion and a gas permeable hydrophobic portion, the gas permeable hydrophobic portion extending from the interior chamber through the vent when the movable vent plug is in an open position, and the solid portion of the vent plug covering the vent when the movable vent plug is in a closed position, wherein the solid portion of the vent plug includes a surface that responds to septum activation by moving the movable vent plug from the open position to the closed position.
