[0001] This invention relates to the field of medical device technology, and in particular to a reagent preparation and application control linkage system. Background Technology

[0002] Blood cell analysis is one of the three major routine clinical laboratory tests and a core supporting means for the diagnosis of blood-related diseases. However, the core technologies of blood analyzers, which combine high precision, strong specificity (capable of accurately identifying abnormal cells), and simultaneous multi-parameter detection, have long been monopolized by foreign companies. While such devices can output key diagnostic data with their efficient detection performance, significantly improving diagnostic accuracy and efficiency, they also suffer from practical problems such as high cost per test, complex instrument maintenance, and high overall operating costs.

[0003] High-speed, high-specificity, and high-throughput blood analyzer pipeline counting systems are typically used in high-level hospitals where the daily sample volume is very large, the required time-to-analyze (TAT) time is very short, reagent consumption is high, reagents need to be replaced frequently, which takes more time and incurs significant manufacturing, transportation, and warehousing costs for storing reagents, resulting in increased testing costs and human resource consumption. Summary of the Invention

[0004] The purpose of this invention is to provide a reagent preparation and application control linkage system, which aims to solve the problem of traditional blood analyzer automated counting systems incurring high manufacturing, transportation, and storage costs for reagent storage.

The first reagent storage tank (CONC-DIL1) and the second reagent storage tank (CONC-DIL2) are used to store the diluted reagent. The buffer tank (CONC-DIL) is used to provide concentrated reagent (CONC-DS) at normal pressure. The purified water source (RO) is externally supplied purified water with a power source.

The mixing device (MIX1) is the first mixing and dilution unit, and the gas-liquid mixing device (MIX2) is the second mixing and dilution unit, and performs suction and discharge functions. The large liquid storage chamber (dilution DSL tank) is used to store the diluted reagent. The dual-head air pump (P1) provides air to the negative pressure gas storage device (PT1) and the positive pressure gas storage device (PT2). The suction pump (D-PUMP) attracts and quantifies different reagents and purified water for proportional mixing.
