Reagent constant-temperature system of blood analyzer

The utility model discloses a reagent constant-temperature system of a blood analyzer. The constant-temperature system is arranged inside the blood analyzer, and comprises a constant-temperature device A, a constant-temperature device B, a pipeline A and a pipeline B, wherein the pipeline A is connected with the constant-temperature device A; the constant-temperature device A is connected with a measuring unit through the pipeline B; the constant-temperature device B is positioned right opposite to the pipeline B, and is used for outputting hot air. The constant-temperature system has the advantages that a heating piece is adopted to heat the reagent passing by, so that the agent reaches the set temperature when flowing out of the outlet of the constant-temperature system; in order to reduce the influence of space temperature on the temperature of the reagent inside the pipelines, the constant-temperature system is further provided with the constant-temperature device B used for heating space inside the instrument; the constant-temperature system is small in size, low in energy consumption, high in heating efficiency and high in temperature control precision.
