AI Technical Summary

Technical Problem

In existing blood cell analyzers, the gemstone orifice is prone to clogging, causing the instrument to malfunction. Furthermore, current technology cannot completely clear the clogging or the clearing process takes too long, resulting in waste of reagents and cleaning solutions.

Method used

An impedance detection liquid circuit system is adopted, including a detection cell, a syringe, a solenoid valve, and a connecting pipe. Liquid is drawn from the syringe to backwash the detection cell, and a constant current power supply is used to provide voltage to burn the small hole. The solenoid valve controls the flow of liquid for backwashing.

Benefits of technology

It enables rapid and effective removal of blockages, saves reagent costs, reduces the use of cleaning solution, and improves the working efficiency of the instrument.

Abstract

The application discloses an impedance detection liquid path system, a blockage discharging method and a blood cell analyzer. The system comprises a syringe, a first joint, a second joint, a first electromagnetic valve and a communication pipe. The inlet and outlet of the syringe are connected and communicated with the first port of the first electromagnetic valve through the communication pipe and the first joint. The second port of the first electromagnetic valve is connected and communicated with the first back pool end of a detection pool through the communication pipe and the second joint. The syringe is used for pumping liquid in the detection pool through the first back pool end when the first electromagnetic valve is opened, and the detection pool is backflushed by the pumped liquid. The detection pool is backflushed by the syringe to pump liquid in the detection pool, so that the blockage discharging problem can be solved in a short time, and the reagent cost is saved.
