FLUID CONNECTORS WITH MODULAR CONNECTION STATE SENSORS
Quick connect fluid connectors with modular connection state sensors removably or detachably mounted thereon. Each modular connection state sensor is configured to sense a connection state of the fluid connector it is mounted on. The connection state sensor indicates that the fluid connector of the first fluid system is connected to the second fluid system prior to initiating fluid flow between the first and second fluid systems.

The elements that are sensed can be, for example, one or more cylindrical sleeves of the fluid connector or a piston of the fluid connector. Therefore, the connection state of the fluid connectors can be determined accurately.
