Flowing path system

Abstract

The invention relates to a flowing path system, which is used for a blood gas electrolyte analysis instrument or an electrolyte analysis instrument. The flowing path system comprises a flowing path control part, a sampling part, a sample analysis part, a reagent part and a gas source forming part, wherein the sampling part, the sample analysis part, the reagent part and the gas source forming partare connected with the flowing path control part respectively; the sampling part is connected with the sample analysis part; the reagent part comprises a reagent bag and a waste liquid bag; a reagententers the flowing path system through the reagent bag, and flows into the waste liquid bag sequentially through the flowing path control part, the sampling part, the sample analysis part and the flowing path controlling part; the gas source forming part comprises a gas pump, a gas storage tank and a pressure reducing valve; compressed gas enters the gas storage tank through the gas pump; after the pressure reduction through the pressure reducing valve, the gas sequentially passes through the flowing path control part, the sample analysis part, the sampling part, the flowing path control partand the reagent part; residue reagents in the flowing path system are flushed to enter the waste liquid bag. The compressed gas is used for reverse flushing; most residue reagents in the flowing pathare cleanly flushed; the instrument has little crossed pollution during the measurement of a plurality of samples; the performance is more stable.

Description

technical field [0001] The invention relates to an electrolyte analyzer, in particular to a flow path system which can be used in a blood gas electrolyte analyzer or an electrolyte analyzer. Background technique [0002] At present, the performance of domestic blood gas and electrolyte analyzers tends to be stable, and the flow path design is becoming more and more mature, but it is also a common phenomenon that the flow path of medical instruments is not cleaned cleanly. The measures currently taken mainly include enhancing the cleaning ability of the cleaning solution, changing the flow path regularly, and artificially degreasing the instrument. Although the former has a certain effect on cleaning the flow path, it will also have a certain impact on sensitive electrodes and shorten the life of the electrodes; the latter has no effect on the electrodes, but requires higher skills for users and increases labor intensity.
