1. A medical connector comprising:
a housing with a central axis and a hollow bore, wherein the hollow bore comprises a narrowed passage connecting a first region of the hollow bore with a second region of the hollow bore, the narrowed passage having a cross-sectional width that is smaller than a cross-sectional width of the first region of the hollow bore adjacent the narrowed passage, the narrowed passage also having a cross-sectional width that is smaller than a cross-sectional width of the second region of the hollow bore adjacent the narrowed passage; a rigid valve member configured to translate along the central axis in the hollow bore of the housing, the valve member comprising an internal passageway, a closed end, and a hole near the closed end of the valve member, wherein the hole extends through a portion of the valve member; a resilient member coupled to the valve member and the housing; and a sealing portion disposed within the housing and configured to inhibit fluid communication through the hollow bore of the housing between an interior surface of the housing and an exterior of the valve member; wherein the connector has a first position in which at least a portion of the closed end of the valve member extends into the narrowed passage such that there is no impediment between the closed end of the valve member and the second region of the hollow bore, wherein the valve member is configured such that fluid is not permitted to flow through the hole in the first position, and wherein the connector has a second position in which fluid is permitted to flow through the hole. |
