Abstract
A system for collection of blood during surgery includes an interlock that requires conduits supplying collected blood to a bag to be properly connected before the system is operated. The interlock includes a source of electromagnetic energy that illuminates connectors to determine whether they are connected. In a preferred embodiment, the connector is a Luer connector with a cylindrical portion that redirects the electromagnetic energy when the connector is in place.
