Cleaning fluid dosage prediction method and sample analyzer

Abstract

The embodiment of the invention discloses a cleaning fluid dosage prediction method and a sample analyzer, which are used for dynamically predicting the dosage of cleaning fluid to avoid the situation that a test process is influenced by pause of a started test item. The method comprises the steps: obtaining liquid suction device information, reagent information and the remaining amount of cleaning liquid of a first test item, wherein the first test item comprises at least one liquid suction device and at least one reagent, the liquid suction device information comprises the number of the liquid suction devices, and the reagent information comprises the number of the reagents; respectively calculating the demand amount of the second cleaning liquid required when a single liquid suction device sucks each reagent; summing the demand amount of the second cleaning fluid corresponding to each reagent to obtain the demand amount of a first cleaning fluid required by each liquid absorption device in the first test item; summing the demand amount of the first cleaning fluid corresponding to the liquid suction devices to obtain the first total amount; and if the first total amount is smaller than the residual amount of the cleaning liquid, starting the first test item.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a cleaning solution consumption prediction method and a sample analyzer. Background technique [0002] The sample analyzer can test samples containing multiple test items at the same time, and the reagents used for different items may be different, while the sample analyzer may only have one liquid suction device, which needs to absorb different reagents when testing multiple items , there may be cross-contamination between items leading to poor testing. [0003] In order to avoid this situation, when the previous reagent absorbed by the liquid suction device will cause cross contamination to the latter item, before the liquid suction device absorbs the latter reagent, the liquid suction device needs to be cleaned with a cleaning solution. Reduce cross contamination. [0004] However, the cleaning solution stored in the sample analyzer is limited. If the cleaning soluti...

[0004] However, the cleaning solution stored in the sample analyzer is limited. If the cleaning solution is used up during the test and the test is not stopped, it will also cause cross-contamination. Therefore, the sample analyzer needs to avoid still testing after the cleaning solution is used up.
