Abstract: A method and system for communicating estimated blood loss parameters of a patient to a user, the method comprising: receiving data representative of an image, of a fluid receiver; automatically detecting a region within the image associated with a volume of fluid received at the fluid receiver, the volume of fluid including a blood component; calculating an estimated amount of the blood component present in the volume of fluid based upon a color parameter represented in the region, and determining a bias error associated with the estimated amount of the blood component; updating an analysis of an aggregate amount of the blood component and an aggregate bias error associated with blood loss of the patient, based upon the estimated amount of the blood component and the bias error; and providing information from the analysis of the aggregate amount of the blood component and the aggregate bias error, to the user.

Abstract: Methods for characterizing fluids from a patient. A time series of images of a conduit are received, and a conduit image region in the images is identified. The conduit image region may include a shallow section and/or a deep section. The shallow section includes a dimension of the conduit along an optical axis of the camera such that opacity of the fluids from redness associated with red blood cells or hemoglobin is limited to permit pixel color visualization in the images. The deep section includes a dimension is along the optical axis such that the redness provides a minimum opacity to permit the pixel color visualization. A concentration of a blood component of the fluids is determined based on the pixel color visualization. A volume of blood passing through the conduit is estimated based on the estimated concentration of the blood component and an estimated volumetric flow rate.

Abstract: A method for analyzing a surgical textile. A depth image and a color image of the surgical textile is acquired. One or more processors analyze a depth map of the depth image to apply one or more image classifiers. Blood information is extracted from pixels of the color image if the depth image satisfies the classifier(s). The classifier(s) may be a perimeter classifier, a planarity classifier, a normality classifier, a distance classifier, and/or a color classifier, among others. The distance classifier may include transforming pixel dimensions of a selected surface in the depth image into real dimensions based on distance values of the pixels. A graphical representation may be displayed to indicate the need to move the surgical textile closer or farther to satisfy the distance classifier. A prompt may be displayed to manipulate the surgical textile prior to the steps of acquiring the depth image and the color image.

Abstract: Systems and methods for estimating a blood volume within a canister. The system may include means for detecting a fluid level of the fluid, such as a float sensor mechanism disposed within the canister. An imaging device captures an image of the fluid within the canister. A processor determines an estimated concentration of a blood component in the fluid based on the image. The processor determines a canister volume of the fluid based on the detected fluid level, and estimates the blood volume within the canister based on the estimated concentration of the blood component and the determined canister volume. The processor may trigger the imaging device to capture the image based on a change in the canister volume. An insert may be arranged within the canister and positioned adjacent to and offset from a transparent region of the canister.

Abstract: A computer-implemented method and system for estimating fluid loss. A graphical representation of a container is displayed. User inputs to display elements may include incrementing or decrementing sliding markers to desired set positions. A first user input may indicate a volume of a second fluid, and a second user input may indicate a total volume of fluid. A first volume of a first fluid may be estimated based on the first and second user inputs. A graphical representation of the first volume of the first fluid may be displayed as a fluid level within the graphical representation of the container. A second volume of the first fluid contained in an absorbent article may be estimated based on a difference between a dry weight and a wet weight measured on a scale. A quantity of the first fluid may be estimated based on the first and second volumes.
