Positive displacement fluid lock port
First Claim
1. A medical flushing and/or locking system, the system comprising:
- a syringe having a nose;
a housing having a first end configured for engagement with the nose of the syringe and a second end configured for engagement with a medical device, the housing supporting a resilient conduit which defines a lumen for establishing fluid communication between the syringe and the medical device when the housing is connected to the syringe and the medical device, the resilient conduit having a first condition wherein the resilient conduit is substantially undeformed and a second condition wherein the resilient conduit is deformed such that the lumen is at least partially occluded;
a biasing mechanism disposed about the resilient conduit, the biasing mechanism configured to transition the resilient conduit from the first condition to the second condition; and
a cap positionable within the resilient conduit to maintain the resilient conduit in the first condition, the cap being selectively removable from the lumen;
wherein the nose of the syringe is dimensioned to maintain the resilient conduit in the first condition after removal of the cap.

Abstract
Positive displacement fluid lock ports for use in combination with an indwelling catheter and a syringe during a flushing/locking procedure are provided. The fluid lock port includes a housing having a distal and a proximal end; a resilient conduit supported within the housing, wherein the conduit defines a lumen therethrough; and at least one biasing member supported in the housing and being operatively associatable with the resilient conduit. 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.
