Medical connectors and methods of use
View Patent ↗A medical connector for use in a fluid pathway includes a substantially transparent housing having a proximal end with a proximal opening and a distal end with a distal opening, and a cavity extending therebetween. The connector provides a substantially visible fluid flow path extending through a substantial portion of the connector.
1. A medical connector for use in a fluid pathway, the connector comprising:
a housing having a proximal region with a proximal opening and a distal region with a distal opening, and a housing cavity extending between the proximal and distal openings, the housing being transparent in that at least a portion of the housing cavity is visible through the housing;
a valve member having an interior valve cavity, the valve member being disposed within the housing cavity and being transparent in that at least a portion of the interior valve cavity is visible through the valve member, and the valve member having a proximal opening that is biased closed to obstruct fluid flow through the proximal opening, wherein the valve member is configured to selectively obstruct fluid communication between the housing proximal opening and the interior valve cavity when the valve member is provided in a first position and to permit fluid communication between the housing proximal opening and the interior valve cavity when the valve member is in a second position; and
a support member fixed relative to the housing, the support member comprising an elongate portion positioned in the interior valve cavity, the support member having an inner conduit that extends from adjacent a proximal tip portion to a distal region of the support member, the support member having at least one opening that extends through the support member to the inner conduit, and the support member being transparent in that at least a portion of the inner conduit is visible through the support member, wherein the fluid communication between the housing proximal opening and the interior valve cavity is permitted in the second position when the proximal tip portion and the at least one opening of the support member protrude through the valve proximal opening; and
wherein at least a portion of the inner conduit is visible through at least a portion of each of the housing, the valve member, and the support member.
2. The medical connector of claim 1 , wherein the valve member sealingly engages internal surfaces of the housing cavity.
3. The medical connector of claim 1 , wherein the valve member obstructs entry of contamination into the housing cavity.
4. The medical connector of claim 1 , wherein the valve member further comprises a radially outwardly extending protrusion.
5. The medical connector of claim 1 , wherein the housing comprises a body and a base, and a portion of the body overlaps a portion of the base.
6. The medical connector of claim 5 , wherein the base is transparent such that at least a portion of an interior of the base is visible through the base.
7. The medical connector of claim 5 , wherein the body is transparent such that at least a portion of an interior of the body is visible through the body.
8. The medical connector of claim 1 , comprising a second valve member positioned between the proximal tip portion of the support member and a distal end of the housing.
9. The medical connector of claim 8 , wherein the second valve member is substantially transparent.
10. The medical connector of claim 8 , wherein the housing comprises a base and a body that overlaps at least a portion of the base, and wherein the second valve member is positioned at least partially within the base.
