1. A fluid lock port for inter-connection between a first medical device providing a flushing and/or locking fluid and a second medical device requiring a flushing and/or locking fluid, the fluid lock port comprising:

  • a housing having a distal and a proximal end;

    a resilient conduit supported within the housing, wherein the conduit defines a lumen therethrough;

    at least one biasing member supported in the housing and being operatively associatable with the resilient conduit, wherein the at least one biasing member has a first condition restrained from deforming the resilient conduit and a second condition operatively engaged with the resilient conduit to at least partially occlude the lumen of the resilient conduit;

    wherein the at least one biasing member is a resilient ring disposed about the resilient conduit, wherein the resilient ring includes a substantially circular biased condition and a substantially oval un-biased condition; and

    wherein the housing includes a shoulder configured to support the resilient ring in the biased condition out of engagement with the resilient conduit; and

    at least one actuation member configured to move the resilient ring off of the shoulder of the housing and onto the resilient conduit, wherein each actuation member is a pin slidably supported in the housing, wherein each one actuation member has a first condition in which each actuation member does not extend over the shoulder of the housing and a second condition in which each one actuation member at least partially extends over the shoulder of the housing.
