Abstract

The invention discloses a blood sample analyzer and a rapid sample analysis system and method. The blood sample analyzer comprises a sampling needle, an RBC / HGB test solution preparation pool and at least two DIFF pools. Blood sample collection and separate injection are completed through the sampling needle, the number of the reaction units is strictly controlled, the occupied time of the sampling needle for executing sample separate injection to the reaction units is correspondingly shortened, continuous and rapid detection of constant blood samples and trace blood samples is achieved, and the highest detection speed is larger than or equal to 200 T / h. Meanwhile, the blood sample analyzer is low in sample consumption demand, and the consumption of the required reaction reagent can be reduced along with the reduction of the sample size, so that the detection cost can be reduced. Meanwhile, the optical detector only carries out DIFF channel detection once, the flow of sample liquid can be controlled to be below 8uL / s, the pressure of sheath liquid needing to be matched can be less than 120kpa, and the problems of high process difficulty and high cost of existing rapid blood analysis are well solved.
