Abstract: Methods and systems for characterizing fluids from a patient are disclosed. The method includes receiving a time series of images of a conduit receiving fluids from the patient, identifying a conduit image region in each of the images, classifying a flow type through the conduit based on an evaluation of the conduit image region in the time series of images, and estimating at least one of a volume of fluids and a quantity of a blood component that has passed through the conduit within a predetermined period of time, based at least in part on the classification of the flow type.

Abstract: A system performs a method for processing an image of a machine-readable code. The method includes receiving an image of a machine-readable code comprising coded information, where the machine-readable code is at least partially obscured. An adjusted image is generated by adjusting a color space of the image. At least a machine-readable code region of the image is binarized, wherein the machine-readable code region of the image depicts the machine-readable code. The binarized machine-readable code region is decoded to determine the coded information. Other apparatus and methods are also described.

Abstract: A method of estimating blood loss of patient fluid within a fluid canister. A camera may automatically capture one or more images of the fluid canister based on a detected change in volume of patient fluid within the fluid canister exceeding a threshold. The image is analyzed determine the volume of the patient fluid, and a blood concentration of the patient fluid within the fluid canister. The blood loss is estimated based on the volume and the blood concentration, and displayed on a display. A pixel-based height of the patient fluid within the fluid canister may be calculated based on the surface of the patient fluid. The pixel-based height may be converted to the estimated fluid volume. The image may be a frame of a multi-frame video feed. The image(s) of the multi-frame video feed may be analyzed as the patient fluid is being drawn into the fluid canister.

Abstract: A method for estimating extracorporeal blood volume in at least a portion of a physical sample. A feature is extracted from an image of the physical sample. The extracorporeal blood volume in the portion of the physical sample is estimated. The estimation may be based on the extracted feature and at least one of the estimated distance and the estimated angle between a capture origin of the image and the portion of the physical sample based on a returned signal transmitted from a distance sensor. The estimated extracorporeal blood volume may be displayed on a display, such an augmented reality overlay in which the image of the portion of the physical sample is displayed with at least one of the estimated extracorporeal blood volume or a sample counter. The sample counter may be indexed for the physical sample after estimating the extracorporeal blood volume.

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. A flow type of the fluids passing through the conduit may be classified as one of air, laminar liquid, and turbulent liquid by evaluating an air-liquid boundary of the fluid. A volumetric flow rate of the fluids in the conduit is estimated. The volumetric flow rate may be based on the classified flow type. A concentration of a blood component of the fluids passing through the conduit may be estimated based on the images. A proportion of the fluid that is blood may also be determined, and a volume of blood that has passed through the conduit within a predetermined period of time may be estimated based on the estimated total volumetric flow rate and the determined proportion.
