Reagent replacement method and device of an analyzer

A sample analyzer, comprising:

• a plurality of original reagent containers configured to provide original reagents;
• a detector collocated with the plurality of original reagent containers;
• a plurality of reservoirs configured to receive the original reagents from the plurality of original reagent containers;
• a plurality of pipelines between the plurality of original reagent containers and the plurality reservoirs configured to transfer the original reagents;
• an analysis module including:
• a reaction container;
• a suction sampler configured to:
• collect a sample from a sample container;
• and
• a moving mechanism configured to move the suction sampler over the sample container and the reaction container;
• wherein the analysis module is configured to:
• mix the collected sample with a reagent from at least one of a plurality of original reagent containers for reaction in the reaction container;
• and
• test the sample after the reaction;
• a human-machine interaction module comprising a screen configured to display a reagent setup window;
• an input device configured to receive reagent information from the plurality of original reagent containers;
• and;
• a processor connected with the analysis module and the human-machine interaction module and configured to:
• detect a stoppage of sample conveying;
• receive first information indicating one or more of failed reagents containing expired or insufficient reagents based on the reagent information received by the input device;
• instruct the screen to automatically pop up the reagent setup window and display failure information upon receiving the first information;
• receive second information indicating that a replacement reagent container containing a replacement reagent has been detected by the detector;
• and
• instruct the screen to replace the failure information with information of the replacement reagent in the reagent setup window, wherein the information of the replacement reagent comprises at least a reagent name and a reagent expiration date;
• start a timer of a fixed time period and pop up a button on which countdown of the fixed time period is displayed in response to that all failure information in the reagent setup window has been replaced with information of replacement reagents;
• automatically close the reagent setup window without user input in response to expiration of the fixed time period, or immediately close the reagent setup window in response to a user input on the button before the countdown is finished;
• and
• after the reagent setup window is closed, control the replacement reagent to be aspirated from the replacement reagent container into a reservoir for a failed reagent to replace the failed agent through a corresponding delivery pipeline connected between the replacement reagent container and the reservoir for the failed reagent;
• wherein the input device comprises a scanner;
• wherein the processor is further configured to:
• obtain the information of the replacement reagent from the scanner;
• determine a location in the reagent setup window for displaying the information of the replacement reagent according to the reagent name of the replacement reagent;
• and
• input at least part of the information of the replacement reagent into the location in the reagent setup window;
• or
• wherein the processor is further configured to:
• receive user input at the location in the reagent setup window to obtain the information of the replacement reagent.
