A releasable coupling device for a medical line comprises a first valve assembly 100 with a first valve biased to a closed position, the first valve assembly 100 for attaching to the end portion of a line segment 12. It further comprises a second valve assembly 200 with a second valve biased to a closed position, the second valve assembly 200 for attaching to a medical device 8.A coupling assembly 300 has a conduit therethrough and releasably couples to both the first valve assembly 100 and the second valve assembly 200. When coupled to the valves 100, 200, the coupling assembly 300 opens them, allowing fluid to flow from the first line segment 12 through the coupling assembly 300 to the medical device 8. A releasable coupling means 400 releasably holds the coupling assembly 300 coupled to both the first and second valve assemblies 100, 200. The releasable coupling means 400 releases the coupling assembly 300 from both the valve assemblies 100, 200 when the first line segment 12 and medical device 8 are subjected to a sufficiently high separation force. Preferably the releasable coupling means 400 is a spring clip. |
