Method for estimating a quantity of a blood component in a fluid canister
First Claim
1. A method for assessing concentration of a fluid component within a container, comprising:
- at a computing system in communication with an image acquisition device, receiving data associated with an image of the container generated by the image acquisition device;
detecting a color grid in the image, the color grid comprising an array of color elements, wherein each color element of the color grid is associated with at least one of a set of colors;
generating an adjusted image by adjusting a color setting in the image to align a color characteristic of a first color in the set of colors to a true color characteristic of the first color; and
determining a concentration of the fluid component based on a region of the adjusted image associated with the container.

Abstract
A system and method for assessing the concentration of a fluid component within a container, the method comprising: receiving data associated with an image of the canister; from the image, detecting a color grid comprising color elements coupled to the canister,; selecting a region of the image corresponding to a portion of the canister; determining a match between a detected color of the region and a shade in the set of colors associated with the color grid captured in the image; based upon a position of a color element corresponding to the shade in the color grid, retrieving a concentration of the blood component associated with the shade of color.

10. A method for assessing concentration of a fluid component received at a fluid receiver, the method implemented at a computer system and comprising:
-
receiving data associated with an image of the fluid receiver; detecting a color grid in the image, the color grid comprising an array of color elements in proximity to the fluid receiver, wherein each color element of the color grid is associated with at least one of a set of colors; generating an adjusted image by adjusting a color setting in the image to align a color characteristic of a first color in the set of colors to a true color characteristic of the first color; and determining a concentration of the fluid component based on a region of the adjusted image associated with the container. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system for assessing an amount of a fluid component, the system comprising:
-
a fluid receiver and a color grid comprising an array of color elements in proximity to the fluid receiver, wherein each color element of the color grid is associated with at least one of a set of colors; an image acquisition device configured to capture an image of the fluid receiver and the color grid within a window of view; and a computing system in communication with the image acquisition device and comprising; a first module configured to detect the color grid within the image; a second module configured to determine a first true color characteristic of a first color in the set of colors captured in the image, based upon a position of the first color in the color grid in the image; a third module configured to generate an adjusted image by adjusting a color setting of the image to align a first color characteristic of the first color to the first true color characteristic of the first color; a fourth module configured to determine a concentration of the fluid component from a region of the adjusted image corresponding to a portion of the fluid receiver; and a fifth module configured to generate an analysis indicative of the amount of the fluid component at the fluid receiver, based upon the concentration of the fluid component and a volume of fluid received at the fluid receiver. - View Dependent Claims (19, 20, 21)
