Abstract

See full text

A flow meter includes a coupler, a support member, an image sensor, and one or more processors. The coupler is adapted to couple to a drip chamber. The support member is coupled to the coupler. The image sensor has a field of view and is operatively coupled to the support member. The image sensor is positioned to view the drip chamber within the field of view. The processor is operatively coupled to the image sensor to receive image data from the image sensor and is configured to: capture an image of a drip chamber using an image sensor; compare the image of a drip chamber with a dynamic background image; and adjust a flow rate of fluid flowing through the fluid line in accordance with the comparison between the image of the drip chamber and the dynamic background image.
