d. Calibrating the degree of needle blockage through the output differential voltage signal, for example, when 25% of needles are blocked, 50% of needles are blocked, 75% of needles are blocked or the needles are completely blocked, corresponding to the differential voltage signal in the corresponding needle blockage state, and judging the degree of needle blockage of the waste liquid needle 4 according to the calibrated differential voltage signal in the subsequent test;
