METHOD AND DEVICE FOR EVALUATING BUBBLE DETECTOR, BUBBLE DETECTOR, AND ARTIFICIAL DIALYZER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for evaluating a bubble detector, in which handling for fine bubbles is eliminated, the detectability for the fine bubbles in a liquid conveying pipe is evaluated precisely, dispersion of their sizes is reduced, and which provides easily high precision, to provide a highly reliable and highly sensitive bubble detector, and to enhance safety and reliability for an artificial dialyzer. ;SOLUTION: A detector 10 is arranged in a liquid conveying pipe 1 filled with a liquid to sandwich the pipe 1, a substance comprising known sizes of solids 4 is supplied, the solids 4 moves in the liquid to provide signals through the detector 10, when passing through the detector 10, and the presence of bubbles and their sizes are determined, based on the detected signals in the detector 10. The correlation between the signals of the detector 10, in response to the sizes of the substance comprising the solids 4 and the signals of the detector 10 in response to the sizes of the bubbles, is used for evaluation of size. The bubble detector 10 is provided with a detector for detecting known sizes of fine solids, and such the detector 10 is mounted on an artificial dialyzer.;COPYRIGHT: (C)2000,JPO
