1. A method of manufacturing a surgical waste collection manifold with a volume collected datum and a rover type to ensure compatibility with a surgical waste collection rover, the surgical waste collection rover including a vacuum pump and a receiver defining an opening, the method including:
obtaining a used first manifold comprising a first housing defining a surface, the first housing defining a first manifold volume and a first outlet opening in fluid communication with the first manifold volume, a first circuit coupled to the surface of the first housing and being used, the circuit comprising a first memory device including a first memory bank and a second memory bank, the first memory bank of the first circuit including a first memory field including a rover type and a second memory field including a first hash digest based on the rover type, the second memory bank including a third memory field including a volume collected datum, and a fourth memory field including a second hash digest based on the volume collected datum, the first circuit coupled to the surface of the manifold, the used first manifold including a contaminant in the first manifold volume and a time stamp field indicating a time of first use and a contamination bit indicative of prior vacuum;
programming the second memory field of the used first manifold with a third hash digest, the third hash digest different from the first hash digest and being based on the rover type;
programming the fourth memory field of the used first manifold with a fourth hash digest, the fourth hash digest different from the second hash digest and being based on the volume collected datum;
programming a time stamp field on the first memory device indicating that no first use has occurred;
resetting the contamination bit of the first circuit to be indicative of no prior vacuum; and
removing the contaminant from the first manifold volume of the used first manifold to yield a cleaned first manifold.
