Patent ID: 8042838

Claim:
A connection device, comprising: a male luer connector and a female luer connector that are configured to lock by rotating relative to each other and to mate so as to define a continuous flow path between them, said luer connectors being of the type that defines a progressively-expanding opening of the continuous flow path to the outside as the male luer connector withdraws from the female luer connector, said luer connectors being attached at ends of respective tubes, each of said luer connectors being larger in a dimension than a diameter of its respective tube; and a disconnection prevention member having two open ends, each open end defining opposing edges spaced apart so as to create a gap that is large enough for a respective one of the tubes and small enough to form an interference fit with a respective one of said luer connectors attached to the respective tube, the disconnection prevention member being configured such that when said luer connectors are held by the ends of the disconnection prevention member, the male luer connector is prevented from separating, and thereby from being completely removed from, the female luer connector and such that progressive expansion of the opening of the continuous flow path to the outside is prevented, wherein the disconnection prevention member has an intermediate portion arranged between the two open ends and is constructed to interferingly engage with at least one of the luer connectors so as to prevent rotation of said at least one of the luer connectors relative to the other of the luer connectors and thereby prevent unlocking of the luer connectors when the luer connectors are held by the ends of the disconnection prevention member.
