1. A suction regulator device comprising:
a layer defining an entry point, a plurality of channels and a pathway that connects the entry point to the channels, the channels connectible to a vacuum terminal of a vacuum supply system;
at least one sensor located beside the pathway, wherein the sensor is configured to sense a change in clarity of a gas passing from the entry point to the vacuum terminal;
an alerting device that is configured to generate an alert; and
a processor configured to:
receive, from the sensor, a contamination indication based on the sensed change in clarity;
determine, from the indication, that the suction regulator device has been contaminated; and
transmit, to the alerting device, an instruction to generate an alert indicative of contamination.
