The control method provided by the embodiment of the present application will be described in detail below with reference to the working principle of the sample analyzer and the reagent supplying apparatus.

Referring to fig. 6, the control method is applied to a sample analyzer or a reagent supplying apparatus, and includes steps S101 to S102.

And S101, acquiring a reagent state signal output by the liquid level detection assembly, and acquiring a sealing cover state signal output by the sealing cover detection assembly.

The liquid level detection assembly is used for acquiring liquid level information of the reagent storage device, the liquid level information is used for representing the reagent amount in the accommodating cavity of the reagent storage device, whether the reagent amount in the accommodating cavity is smaller than a reagent amount threshold value or not is judged through the liquid level information, and then a corresponding reagent state signal is generated according to a judgment result. And judging whether the sealing cover component is sealed on the reagent storage device or not by the sealing cover detection component, and generating a corresponding sealing cover state signal according to the judgment result.

Illustratively, when the cover assembly is not sealed to the reagent reservoir, this indicates that the operator is performing a reagent change or addition to the reagent supply or that the cover assembly is not properly sealed to the reagent reservoir due to improper handling. When the sealing cover component is sealed in the reagent storage device and the liquid level detection component detects that the reagent amount in the accommodating cavity is smaller than the reagent amount threshold value, the reagent supply device needs to be replaced or added with the reagent. When the sealing cover component is sealed in the reagent storage device and the liquid level detection component detects that the reagent amount in the accommodating cavity is larger than the reagent amount threshold value, the current reagent storage device can continue to provide the reagent required for sample analysis for the sample analyzer, namely, the reagent supply device can work normally.

The controller can control the sample analyzer to execute corresponding preset operation according to the reagent state signal output by the liquid level detection assembly and the cover state signal output by the cover detection assembly.

In some embodiments, the reagent status signal comprises a first reagent status signal indicating that the amount of reagent within the containment chamber is less than a reagent amount threshold; the controlling the sample analyzer to perform corresponding operations based on at least one of the reagent status signal and the lid status signal includes:

and when a first reagent state signal sent by the liquid level detection assembly is received, controlling the sample analyzer to enter a non-preset working mode after a preset task is executed, and generating first prompt information.

Illustratively, as shown in fig. 7, when the liquid level detection assembly 303 detects that the amount of reagent in the reagent storage 301 is less than the reagent amount threshold, it indicates that the reagent is required to be replaced or added by the operator to the reagent supply device 30, and generates the first reagent status signal and the first prompt message. The controller acquires the current working state of the sample analyzer according to the first reagent state signal, and learns whether the sample analyzer is currently in the working state according to the current working state information, and if the sample analyzer is in the working state, the controller controls the sample analyzer to enter a non-preset working mode after preset buffering time after the sample analyzer completes a preset task, wherein the non-preset working mode comprises dormancy, shutdown, pause and the like. At the same time, the controller controls the sample analyzer to generate corresponding first prompt information to prompt the operator of the need for reagent addition or replacement to the reagent supply device 30. The first prompt information can be voice prompt, alarm bell prompt, light prompt, character prompt and the like.

For example, when the liquid level detection assembly 303 detects that the liquid level of the reagent in the accommodating chamber is lower than the preset height H, it indicates that the amount of the reagent in the reagent storage 301 is lower than the reagent amount threshold, and then the liquid level detection assembly 303 generates a first reagent status signal. The controller acquires that the current working state of the sample analyzer is 'sample detection in progress' according to the first reagent state signal, and then the controller controls the sample analyzer to enter a dormant state after the sample analyzer executes the current detection task and after the preset buffer time T. While controlling the sample analyzer to generate a voice prompt "the reagent in the reagent supply is insufficient! ", to prompt the operator to perform reagent replacement or addition to the reagent supply device 30.

In some embodiments, the reagent status signal comprises a second reagent status signal indicative of the amount of reagent within the containment chamber being greater than or equal to a reagent amount threshold; the cover state signal comprises a first cover state signal which represents that the cover assembly covers the opening of the accommodating cavity; the controlling the sample analyzer to perform corresponding operations based on at least one of the reagent status signal and the lid status signal includes:

Illustratively, as shown in fig. 8, when the liquid level detection assembly 303 detects that the reagent liquid level in the accommodating cavity is higher than or equal to the preset height H, that is, the liquid level detection assembly 303 detects that the reagent amount in the reagent storage 301 is greater than the reagent amount threshold, a second reagent state signal is generated. When the cover detection assembly 304 detects that the cover assembly 302 covers the opening of the accommodating cavity of the reagent storage 301 within a preset time period, a first cover state signal is generated. When the controller receives the second reagent status signal and the first cover status signal simultaneously, it indicates that the amount of reagent in the reagent storage 301 is greater than the reagent amount threshold, and the cover assembly 302 covers the opening of the accommodating chamber, it indicates that the reagent supply device 30 does not need to add the relevant reagent and that the reagent supply device 30 can continue to provide the sample analyzer with a sufficient amount of reagent required for operation, and the sample analyzer continues to operate in the current preset operation mode.

In some embodiments, the cover status signal comprises a second cover status signal indicating that the cover assembly is not covering the opening of the accommodating cavity; the controlling the sample analyzer to perform corresponding operations based on at least one of the reagent status signal and the lid status signal includes:

and when a second cover state signal sent by the cover detection assembly is received, controlling the sample analyzer to generate second prompt information.

Illustratively, as shown in fig. 9, when the cover detection component 304 detects that the cover component 302 does not cover the opening of the accommodating cavity within the preset time period, a second cover status signal is generated. When the controller receives the second cap status signal, indicating that the sample analyzer is currently undergoing reagent replacement or addition or that the cap assembly 302 is not properly capped on the reagent reservoir 301 due to improper operation, the controller controls generation of a second notification message that indicates to the operator that the cap assembly is not capped on the reagent reservoir 301. The second prompt information can be voice prompt, alarm bell prompt, light prompt, character prompt and the like.

The current working state of the reagent supply device is detected through the sealing cover detection assembly and the liquid level detection assembly, and the sample analyzer is controlled to execute corresponding operation according to the current working state of the reagent supply device, so that the sample analyzer can be automatically controlled when a reagent is replaced or added to the sample analyzer, and a user can use the sample analyzer more conveniently.
