Method for setting a blood transfusion parameter
First Claim
Patent Images
1. A method for setting a blood transfusion parameter for a patient, the method comprising:
- identifying, at a computing system, a blood transfusion bag in a photographic image generated using an optical sensor in communication with the computing system, and, in a region of the photographic image, a fluid surface within the blood transfusion bag;
extracting, at the computing system, a color feature from a region of the photographic image corresponding to the blood transfusion bag;
identifying, at the computing system, a volume marker printed on the blood transfusion bag in the region of the photographic image;
generating, at the computing system, an estimated volume of fluid in the blood transfusion bag based on the volume marker and the fluid surface;
estimating, at the computing system, a blood component content within the blood transfusion bag based on the color feature and the estimated volume of fluid; and
triggering transfusion from the blood transfusion bag based on the blood component content within the blood transfusion bag and an estimated volemic status of the patient.

Abstract
One variation of a method for setting a blood transfusion parameter for a patient includes identifying a blood transfusion bag in a photographic image; extracting a color feature from a region of the photographic image corresponding to the blood transfusion bag; estimating a blood component content within the blood transfusion bag based on the color feature; and triggering transfusion from the blood transfusion bag based on the blood component content within the blood transfusion bag and an estimated volemic status of the patient.

16. A method for setting a blood transfusion parameter for a patient, the method comprising:
-
identifying, at a computing system, a blood transfusion bag in a photographic image generated using an optical sensor in communication with the computing system, comprising extracting a barcode, from a region of the photographic image corresponding to the blood transfusion bag and retrieving, from a database, a set of data pertaining to allogeneic blood contained in the blood transfusion bag based on the extracted barcode; extracting, at the computing system, a color feature from a region of the photographic image corresponding to the blood transfusion bag; identifying, at the computing system, a volume marker printed on the blood transfusion bag in the region of the photographic image; estimating, at the computing system, a blood component content within the blood transfusion bag based on the color feature; and triggering transfusion from the blood transfusion bag based on the blood component content within the blood transfusion bag and an estimated volemic status of the patient. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
