First clinical experience with the air purge control and electrical remote-controlled tubing clamp in mini bypass.

Most mini bypass systems do not contain a venous and cardiotomy reservoir in the cardiopulmonary bypass (CPB) circuit and lack the capability to remove venous air. In conjunction with the manufacturer the air purge control system, a system which automatically removes air that is captured in a venous bubble trap, has been developed. This system is combined with an electrical remote clamp, which automatically clamps the arterial line in case air leaves the bubble trap.
