System And Method For Estimating Extracorporeal Blood Volume In A Physical Sample

A method for estimating extracorporeal blood volume within a fluid canister, wherein an optical sensor is supported to be facing the fluid canister, the method comprising:

• capturing an image of the fluid canister with the optical sensor;
• extracting a color-related feature from at least a portion of the image;
• estimating a fluid level of fluid within the fluid canister from the image;
• estimating a concentration of hemoglobin based on the extracted color-related feature;
• estimating the extracorporeal blood volume based on the estimated concentration of hemoglobin and the estimated fluid level;
• and
• displaying on a display the estimated extracorporeal blood volume.

A system for determining extracorporeal blood volume in a fluid canister, the system comprising:

• an optical sensor configured to capture an image of at least a portion of the fluid canister;
• a light source;
• a processor in electronic communication with the optical sensor and configured to:
• cause the optical sensor to capture an image of the fluid canister with the light source activated;
• extract a color-related feature from at least a portion of the image;
• estimate a concentration of hemoglobin based on the extracted color-related feature, wherein a correlation of the color-related feature with the concentration of hemoglobin is enhanced by the light source being activated during the step of capturing the image;
• estimate the extracorporeal blood volume based on the estimated concentration of hemoglobin;
• and
• a display in communication with the processor and configured to display the extracorporeal blood volume.
