Abstract
An automatic analysis device including a container filled with a fluid, a pressure source, a probe which separates the fluid within the container, the probe associated with a probe position, a motor which moves the probe, a flow path which connects the probe and the pressure source, the flow path associated with a flow path position, a pressure sensor which measures pressure variations within the flow path corresponding with time series management data, and a sensor which detects a liquid level position within the container. A condition of flow generated within the flow path is estimated based on (i) the time series measurement data and (ii) a reference value of pressure according to fluid pressure based on gravitational acceleration in a position of the pressure sensor calculated based on (a) the probe position or the flow path position and (b) an immersion depth of the probe determined by the sensor.
