摘要： A method of calculating a volume of a drop pendant using a microprocessor. Included in the method are generating a gravity vector based on a direction of gravity with respect to the drop pendant; establishing a reference frame of the drop pendant for an image processing based on a reference point of the drop pendant and the gravity vector; generating a first reference line associated with the reference frame for representing an actual orientation of the drop pendant; generating a second reference line associated with the reference frame for representing a longitudinal axis of a chamber in which the drop pendant is located; comparing the first and second reference lines with respect to the gravity vector; and calculating the volume of the drop pendant based on the comparison of the first and second reference lines and the gravity vector.

摘要： A drip chamber for an infusion tube, including: a first end including a drip tube; a second end including an exit port; and a wall connecting the first and second ends and including an interior surface with a hydrophobic portion. The drip chamber includes a space enclosed by the interior wall and the first and second ends. The hydrophobic portion of the interior surface repels liquid contacting the hydrophobic coating. The hydrophobic portion of the interior surface enables light to refract through the hydrophobic portion and the wall in the same manner as is the case when the hydrophobic portion is not present on the interior surface.

摘要： An optical imaging system for use with an infusion tube having a drip chamber and an output tube. The drip chamber includes a first portion with a drip tube, a second portion with an exit port, and a third portion between the first and second portions. The optical imaging system includes: an illumination system with at least one light source for emitting light, an optical system, and a memory element storing computer executable instructions. The optical system receives the light transmitted by the output tube or the second portion and transmits data characterizing the received light. The system includes at least one processor configured to execute the computer executable instructions to: detect, using the data, an air bubble in the output tube or the second portion; and determine a volume of the detected air bubble.
