Reagent conveying method, reaction platform and reagent monitoring device

The invention provides a reagent conveying method, a reaction platform and a reagent monitoring device.The reagent conveying method comprises the steps that a reagent in a reagent box is sucked into a liquid storage pipe through negative pressure, and the pressure in the liquid storage pipe is detected to obtain a first pressure value; determining a reagent suction state according to the first pressure value; the reagent in the liquid storage pipe is conveyed into the reaction platform through positive pressure, and the pressure in the liquid storage pipe is detected to obtain a second pressure value; and determining a reagent output state according to the second pressure value. According to the technical scheme provided by the invention, the problem that a fault occurring in a path communicated with the kit or the reaction platform cannot be found in time in related technologies is effectively solved. 本发明提供了一种试剂输送方法、反应平台及试剂监测装置，其中，试剂输送方法包括：通过负压将试剂盒中的试剂吸入至储液管中，并检测储液管内的压力以得到第一压力值；根据第一压力值确定试剂吸入状态；通过正压将储液管内的试剂输送
