AI Technical Summary

Technical Problem

Existing blood cell analyzers suffer from large overall size and low detection efficiency due to the need for multiple waste liquid tanks.

Method used

The instrument receives waste liquid generated during sample testing through a premixing tank and a reaction tank, and discharges the waste liquid using a pressure source, reducing the number of additional waste liquid tanks and simplifying the liquid path structure.

Benefits of technology

This results in a smaller overall size of the blood cell analyzer, higher waste liquid treatment efficiency, and higher overall detection efficiency, while avoiding the increased space and complexity caused by an additional waste liquid pool.

Abstract

The application provides a waste liquid treatment method applied to a blood cell analyzer, the blood cell analyzer comprising a premixing pool, a reaction pool, a sheath flow impedance detection assembly, an optical detection assembly and a pressure source; the waste liquid treatment method comprising: preparing a first sample liquid through the premixing pool and / or preparing a second sample liquid through the reaction pool; receiving, through the premixing pool, a first waste liquid generated in the process of sample detection of the first sample liquid by the sheath flow impedance detection assembly, and / or receiving, through the reaction pool, a second waste liquid generated in the process of sample detection of the second sample liquid by the optical detection assembly; and discharging the first waste liquid in the premixing pool and / or the second waste liquid in the reaction pool out of the blood cell analyzer through the pressure source. The waste liquid of the sheath flow impedance detection assembly and / or the optical detection assembly is discharged into the premixing pool and / or the reaction pool respectively, an additional independent waste liquid pool is not needed to realize waste liquid treatment, the blood cell analyzer is small in size, the waste liquid treatment efficiency is higher, and the detection efficiency is higher.
