Patent attributes
A method and apparatus are provided for use with a pump. The method includes, (a) placing liquid in a tube coupled to the pump, (b) injecting an air bubble into the tube in a manner that does not increase pressure within the tube, and such that there is a predetermined volume of liquid between the air bubble and the pump, (c) using the pump to advance the air bubble along the tube to the bubble detector of the pump, (d) using the pump, assessing accuracy of the pump by automatically measuring the volume of liquid pumped to advance the air bubble to the bubble detector, and (e) using the pump to continue advancing the air bubble along the tube, past the bubble detector, and using the pump to measure a volume of the air bubble. Other applications are also described.
