Systems and methods for estimating a blood volume within a canister

A system comprising:

• a canister configured to receive fluid from a patient, wherein at least a region of the canister is transparent;
• means for detecting a fluid level of the fluid;
• an insert disposed within the canister and arranged within the canister and positioned adjacent to and offset from the transparent region;
• an imaging device configured to capture an image of the insert and the fluid within the canister;
• and
• a processor configured to estimate a concentration of a blood component in the fluid based on the captured image, determine a canister volume of the fluid based on the fluid level, and determine blood volume within the canister based on the estimated concentration of the blood component and the determined canister volume of the fluid.

A method of estimating a blood volume within a canister with a system including the canister, a float sensor mechanism, an imaging device, and a processor, the method comprising:

• receiving, with the processor, an image of fluid within the canister captured by the imaging device;
• determining, with the processor, an estimated concentration of a blood component in the fluid based on the image;
• detecting, with the float sensor mechanism, a fluid level of the fluid within the canister;
• determining, with the processor, a canister volume of the fluid based on the detected fluid level;
• and
• estimating, with the processor, the blood volume within the canister based on the estimated concentration of the blood component and the determined canister volume.
