Abstract
Automatic substance preparation and evaluation systems and methods are provided for preparing and evaluating a fluidic substance, such as e.g. a sample with bodily fluid, in a container and/or in a dispense tip. The systems and methods can detect volumes, evaluate integrities, and check particle concentrations in the container and/or the dispense tip.
Claims30
A method of evaluating a liquid substance in a container of a dispense device for improving dispensing accuracy of the dispense device, the method comprising:
- capturing, using an image capture device, an image of at least a portion of the container;
- identifying, using the at least one computing device, a reference point in the image, which reference point is associated with the container;
- identifying, using the at least one computing device, a surface level of the liquid substance within the container in the image;
- measuring a distance between the reference point and the surface level;
- converting the distance to a volume of the liquid substance based on correlation data, the correlation data including information about a correlation between volumes of a liquid within the container and distances from the reference point to a plurality of surface levels within the container;
- comparing the volume of the liquid substance with a target volume;
- generating calibration information for the dispense device based on the comparison;
- and
- adjusting operational parameters of the dispense device based on the calibration information.
