System and method for estimating a quantity of a blood component in a fluid canister
First Claim
1. A method for assessment of blood within a fluid receiving substrate, comprising:
- at a processor, selecting a region of an image of the fluid-receiving substrate upon detection of a reference marker;
at the processor, generating an estimated volume of blood at the fluid-receiving substrate from the region of the image with a volume estimation algorithm;
at the processor, extracting a feature including a redness value in a red component space from a set of pixels of the region of the image;
at the processor, correlating the feature with a concentration of a blood component at the fluid-receiving substrate;
at the processor, estimating a quantity of the blood component at the fluid-receiving substrate based on the estimated volume and the concentration of the blood component at the fluid-receiving substrate; and
at an electronic device in communication with the processor, providing information indicative of the quantity of the blood component at the fluid-receiving substrate.

Abstract
A variation of a method for estimating a quantity of a blood component in a fluid canister includes: within an image of a canister, identifying a reference marker on the canister; selecting an area of the image based on the reference marker; correlating a portion of the selected area with a fluid level within the canister; estimating a volume of fluid within the canister based on the fluid level; extracting a feature from the selected area; correlating the extracted featured with a concentration of a blood component within the canister; and estimating a quantity of the blood component within the canister based on the estimated volume and the concentration of the blood component within the canister.
