Medical connector

摘要

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.

主权项

1. A luer connector configured to provide a permanent connection between medical devices, the medical connector comprising:
a rigid housing having a first end portion configured to be engageable with a first device or medical implement and positioned at a first end of the housing and a second end portion comprising an end cap portion; the end cap portion being positioned at a second end portion of the housing, the end cap portion configured to be engageable with a corresponding portion of a second device or medical implement, the end cap portion comprising:
an end cap component having a first body portion, a second body portion, and a flow lumen extending axially through the end cap component; andan annular covering portion extending in a radial direction away from the end cap component, the annular covering being positioned axially between the first body portion and the second body portion; a valve member configured to alter the flow of a fluid through a hollow bore of the luer connector; wherein:
the end cap portion is supported by the housing such that, in an assembled state, the first body portion of the end cap portion is positioned within the housing and such that the annular covering portion and the second body portion are positioned outside the housing;the end cap portion is configured to rotate substantially freely in either a first direction or a second opposite direction relative to the housing and is configured to inhibit the ability of the connector from becoming decoupled from the corresponding portion of the second device or medical implement;the valve member at least partially extends through the housing in an axial direction and comprises:
a first opened end and a second end;a passageway within the valve member;at least one opening near the second end of the valve member extending outwardly from the passageway through the valve member;at least one strut connected to the valve member and extending towards the second end of the valve member, the at least one strut extending substantially parallel to the central axis of the valve member and at least partially surrounding a narrow section of the valve member ending in the second end;a retaining member configured to couple the valve member and the housing; anda sealing element disposed within the housing and configured to inhibit fluid communication through the hollow bore of the housing between the interior of the housing and an outer surface of the valve member.
