Problems solved by technology

This method first ensures the accurate counting of CRP, but the counting time is long due to multiple suction samples, which affects the detection speed. At the same time, this method of secondary sample suction is only suitable for some semi-automatic instruments. Fixed test tube holder, not suitable for some fully open models

Abstract

The invention discloses a sample collection and distribution system and method in a pre-dilution mode, and a blood cell analyzer. The system comprises at least two detection cells, a first injector with a first capacity, a second injector with a second capacity, and a sampling assembly with a sampling needle. Each detection pool comprises at least one counting detection pool and at least one immunodetection pool, the first injector is connected with the second injector through a first pipeline, and the second injector is connected with the sampling assembly through a sampling pipeline; and each counting detection pool is connected with the first injector through a second pipeline corresponding to the counting detection pool, and each immunodetection pool is connected with the first injector through a third pipeline corresponding to the immunodetection pool. According to the system, mixed samples required by detection can be sucked only by one sample collection process, the number of blood cells actually participating in the detection process is increased, the change of reagent and sample sizes is small, the change of a reaction system is small, and the detection result is stable.

Description

technical field [0001] The invention relates to the field of blood detection and analysis, in particular to a blood cell analyzer. Background technique [0002] Blood cell analyzers generally have two modes: whole blood mode and pre-dilution mode. [0003] In the whole blood mode, the common technology is to connect a high-precision 100ul syringe to the sampling needle, insert the sampling needle into the blood collection tube after the blood collection tube is fully shaken, and use the 100ul syringe to provide power to collect the blood sample to the sampling needle and connect it within the pipeline. The relatively complete modes of the current blood cell analyzer include CBC (detection of the number of white blood cells, red blood cells and platelets), diff (four-category statistical technique of white blood cells) and CRP concentration detection and or SAA reaction concentration detection, so the capacity of 100ul is enough to provide A complete sample of CBC+DIFF+CRP ...
