Abstract

The invention relates to an automatic analysis device and a liquid pumping monitoring method. The automatic analysis device comprises a liquid pumping module, a rotary table, a bubble detection sensorand a control module, wherein the rotary table is provided with a plurality of accommodation positions for accommodating containers; each accommodation position is used for accommodating one container; the bubble detection sensor is arranged at a position above the rotary table and close to a liquid suction port at one end of a pipeline of the liquid pumping module, and is used for detecting whether bubbles exist in the pipeline of the liquid pumping module; the control module is electrically connected with the bubble detection sensor and is used for controlling the liquid pumping module to carry out liquid pumping on the containers and starting to time and if the bubble detection sensor still does not detect out liquid arrival after liquid pumping is started for first duration, reportingan error; and the control module is further used for reporting an error when bubble arrival is still not detected out from the moment at which the liquid arrival is detected out. According to the invention, by arranging the bubble detection sensor above the containers to carry out monitoring on liquid pumping, a space is reasonably utilized, so that mutual occupation for a mounting space with other parts of the automatic analysis device cannot be generated.

Description

technical field

[0001] The present invention relates to the technical field of testing or analyzing materials by means of measuring their chemical or physical properties, in particular to an automatic analysis device, and also to a method for monitoring liquid extraction. Background technique

[0002] Automatic analyzers, such as automatic chemiluminescence diagnostic instruments, need to perform multiple washings for the incubated "magnetic beads-reagent-sample" reaction to remove free substances. Because the magnetic beads, serum, protein and other components in the "magnetic bead-reagent-sample" reaction are very easy to cause the suction needle and pipeline to be blocked, which will affect the measurement of the experimental results, so how to carry out the liquid extraction process in the cleaning process. Effective monitoring is important.

[0003] An automatic analyzer needs to install magnets and other components under the turntable, which will reflect light. If the...
