  • Devices For Image-Based Analysis Of Waste Material Within A Canister
    Publication number: 20250321219
    Abstract: Devices for facilitating image-based determination of a blood component in medical waste. The device may be an insert including means for positioning and supporting the insert within the canister for an imaging feature of the insert to be spaced apart from an inner surface of the canister. The insert may include struts configured to engage ribs of the canister in a press-fit arrangement. The struts may be tapered inwardly toward a base of the canister. The insert may define slots providing fluid communication between a rear side and a front side of the insert. The insert may include a frame configured to be compressed to resiliently deform, and engage the canister in a press-fit arrangement. The insert may include feet for providing a fulcrum to facilitate coupling surfaces of the insert to the inner surface with adhesive.
