Abstract
A system and method for connecting two fluid carrying tubes includes a first tube having a lumen therethrough and an open end, and a bubble elimination port proximate the open end and in fluid communication with the lumen, and a second tube having a lumen therethrough and an open end. The first and second tubes are connected in a first position, wherein the lumen of the first tube and the lumen of the second tube form a fluid-tight circuit and the bubble elimination port is open to the circuit, to eliminate any bubbles in the fluid circuit. The first and second tubes then are connected in a second position, wherein the lumen of the first tube and the lumen of the second tube form a continuous, fluid-tight circuit and the bubble elimination port is closed to the fluid circuit.
