Abstract

The invention discloses an impedance method detection system of a blood cell analyzer and a method for identifying hole blockage of an impedance channel. The method for identifying hole blockage of the impedance channel comprises the steps: acquiring historical average pulse data, and calculating a mean value and a standard deviation of the historical average pulse data; acquiring voltage pulse data of the sampling analysis, and counting average pulses of cells passing through small holes in each unit time; sequentially calculating the front mean value and the rear mean value of each unit time, and judging the unit time of possible hole blockage according to the change conditions of the front mean value and the rear mean value of each unit time; and judging whether hole blockage occurs in unit time of possible hole blockage for the first time, comparing the second variable quantity with a standard deviation of historical average pulse data after judging that hole blockage does not occur in unit time of possible hole blockage for the first time, and judging whether hole blockage occurs in unit time of possible hole blockage for the second time. The identification and report of the whole-process hole blockage condition are realized.

Description

technical field [0001] The present application relates to the technical field of particle detection, in particular to an impedance detection system of a hematology analyzer and a method for identifying blockage of an impedance channel. Background technique [0002] When detecting particles (cells) by the impedance method, the small hole is immersed in the electrolyte solution, and a constant current power supply is connected to both ends of the small hole. When the particle (cell) passes through the small hole, the voltage at both ends of the small hole changes, and the particle (cell) ) the larger the volume, the greater the change in voltage (the larger the voltage pulse). Taking the application in the field of blood detection as an example, according to this principle, the blood is diluted and mixed in the diluent (a reagent that is conductive and has the characteristics of physiological saline), and then passed through the small holes with electrodes at both ends, and th...
