[0017] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0018] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

In addition, the terms "first", "second", and "third" in this application are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features.

[0021] In view of the problem in the prior art that when an instrument reports a fault, the fault cannot be located in time and a lot of manual labor is required to locate the fault, the present application provides a sample analyzer so that the sample analyzer can automatically locate and eliminate its own fault problems, especially locate and eliminate pressure fault problems of a liquid storage device in the sample analyzer, reduce the manual participation rate in instrument fault location, improve the practicality of the sample analyzer, and enhance the user experience of the sample analyzer.

[0022] The sample analyzer provided in the present application includes a liquid storage device, a detection device and a control device.

[0023] The liquid storage device is used to store reagents and provide reagents for sample detection of the sample analyzer, and the detection device is used to detect fault information of the liquid storage device. The control device is connected to the liquid storage device and the detection device, and is used to receive target fault information collected by the detection device, and control the operation of the liquid storage device based on the target fault information.

[0024] Specifically, the target fault information may be fault information that the liquid storage tank in the liquid storage device is not fully filled, and the reasons for the incomplete filling of the liquid storage tank may include pipeline fault information in the liquid storage device, quantitative pump capacity fault information (such as the quantitative pump capacity is too small, resulting in insufficient filling of the liquid storage device), pressure fault information, etc. The control device may check the reasons for the target fault information based on the target fault information, and then control the operation of the liquid storage device based on the target fault information to eliminate the target fault information.

[0025] The target fault information is detected by the detection device, and the control device controls the operation of the liquid storage device based on the target fault information, so that the sample analyzer can automatically judge and eliminate the target fault information, improve the troubleshooting efficiency of the sample analyzer, improve the practicality of the sample analyzer, and enhance the user experience of the sample analyzer.

[0026] Optionally, see Figure 1 , Figure 1 The liquid storage device 1 provided in this embodiment includes a metering pump 11 , a pressure assembly 12 and a liquid storage tank 13 .

[0027] The metering pump 11 is connected to the pressure assembly 12 and the liquid storage tank 13 respectively. The pressure assembly 12 is used to absorb the reagent in the reagent bottle into the metering pump 11, and to pour the reagent in the metering pump 11 into the liquid storage tank 13. Specifically, the metering pump 11 may also be connected to the reagent bottle, and the pressure assembly 12 may provide negative pressure to the metering pump 11, under the action of the negative pressure, the reagent in the reagent bottle is absorbed into the metering pump 11; then the pressure assembly 12 provides positive pressure to the metering pump 11, under the action of the positive pressure, the reagent in the metering pump 11 will be poured into the liquid storage tank 13, the liquid storage tank 13 stores the reagent, and provides the reagent to assist the sample detection when the sample analyzer performs the sample detection.

[0028] The pressure assembly 12 may include a positive pressure pump and a negative pressure pump. The positive pressure pump is used to provide positive pressure to the metering pump 11 , while the negative pressure pump is used to provide negative pressure to the metering pump 11 .

[0029] The detection device is also used to detect the liquid storage volume of the liquid storage tank 13, and transmit target fault information to the control device when the liquid storage volume of the liquid storage tank 13 is less than the preset liquid storage volume, that is, the liquid storage tank 13 is not full. In one embodiment, the detection device may include a liquid level sensor and the like.

[0030] The control device is used to obtain target fault information, determine whether there is a first fault in the fault list, and in response to the first fault in the fault list, control the operation of the pressure component 12 based on the first fault. The first fault is a pressure-related fault.

[0031] Specifically, the preset liquid storage volume can be equal to an integer multiple of the maximum reagent volume required for one sample test in the sample analyzer, and the liquid storage volume in the liquid storage tank 13 must be greater than or equal to the preset liquid storage volume to ensure that reagents can be provided for sample testing in the sample analyzer. In another embodiment, the preset liquid storage volume can also be set by the user based on experience, and this application does not limit this.

[0032] In fact, when the liquid storage device 1 is idle, the pressure component 12 will generally work and cooperate with the metering pump 11 to replenish the liquid in the liquid storage tank 13. Therefore, the liquid storage volume of the liquid storage tank 13 will generally not be less than the preset liquid storage volume. Therefore, when the detection device detects that the liquid storage volume in the liquid storage tank 13 is less than the preset liquid storage volume, it can be considered that there is a problem with the device in the liquid storage device 1, resulting in abnormal filling efficiency in the liquid storage tank 13, making the liquid storage volume in the liquid storage tank 13 less than the preset liquid storage volume. Then the detection device generates target fault information and transmits the target fault information to the control device to transmit the information that the liquid storage tank 13 is not full to the control device.

[0033] After receiving the target fault information, the control device determines whether there is a first fault in the fault list, wherein the first fault is a pressure-related fault, and the fault list is a list formed according to at least one fault information detected by the detection device.

[0034] As mentioned above, during the process of filling the liquid storage tank 13 in the liquid storage device 1 with reagent, the liquid storage tank 13 may not be filled fully due to fault information such as the volume of the metering pump 11 is too small, the pressure provided by the pressure component 12 is too small, the float sensor in the liquid storage tank 13 fails, or the connecting pipe between the liquid storage tank 13 and the metering pump 11 is broken. When the above fault occurs, the detection device can collect at least one fault information and transmit the at least one fault information to the control device, and the control device forms a fault list based on the at least one fault information.

[0035] After the control device obtains the target fault information, the control device can first determine whether there is a pressure-related fault in the fault list and locate the fault information to improve the efficiency of eliminating the fault. In response to the presence of a first fault in the fault list, the operation of the pressure component 12 is controlled based on the first fault.

[0036] Specifically, when a pressure-related fault occurs, the control device can control the operation of the pressure component 12 and adjust the pressure generated by the pressure component 12 so that the pressure generated by the pressure component 12 meets the demand, thereby improving the efficiency of reagent infusion into the liquid storage tank 13, thereby achieving the purpose of the sample analyzer automatically judging and eliminating fault information.

[0037] In this embodiment, the liquid storage volume in the liquid storage tank 13 is detected by the detection device, and when the liquid storage volume in the liquid storage tank 13 is less than the preset liquid storage volume, the target fault information is sent to the control device, so that the control device is informed of the fault information that the liquid storage tank 13 is not fully filled. The control device can further determine whether there is a first fault in the fault list, and in response to the presence of the first fault in the fault list, the operation of the pressure component 12 is controlled based on the first fault, so that the fault is located and eliminated, and the sample analyzer automatically determines and eliminates the fault information.

[0038] Optionally, the sample analyzer further comprises a display device, and the display device is connected to the control device.

[0039] The control device is also used to obtain the current pressure value of the pressure component 12 and control the display device to display a first interface, wherein the first interface is used to display the current pressure value of the pressure component 12 to remind the user to adjust the pressure component 12. In one embodiment, the display device may be a display screen.

[0040] Specifically, the detection device may also include a pressure sensor, which is spaced apart from the pressure component 12 and is used to detect the current pressure value of the pressure component 12. Then, the detection device transmits the detected current pressure value to the control device, and the control device controls the display device to display the current pressure value of the pressure component 12 on the first interface.

[0041] When the user observes that the first interface pops up in the display device, the user can be informed that there is a pressure-related fault in the liquid storage device 1, and the user can adjust the pressure valve connected to the pressure component 12 to adjust the pressure component 12 and adjust the pressure value of the pressure component 12. Furthermore, the pressure value displayed in the first interface will be updated with the user's adjustment, so the user can also determine the progress of the adjustment according to the adjusted pressure value displayed in the first interface, and after the adjustment is completed, the user can close the first interface.

[0042] In one embodiment, in the first interface that pops up on the display device, the initial current pressure value can be marked in red, indicating that the pressure value is too low. After the user adjusts the pressure component 12, when the pressure value meets the requirements (the pressure value is greater than or equal to the preset pressure value, and the preset pressure value can be set by the user), the pressure value can be marked in green to remind the user that the adjustment is completed and the fault is eliminated.

[0043] Optionally, see Figure 1 The liquid storage device 1 further includes a first valve 14 and a second valve 15. The quantitative pump 11 is connected to the pressure assembly 12 through the first valve 14, and is connected to the liquid storage tank 13 through the second valve 15. The quantitative pump 11 is also connected to the reagent bottle through the second valve 15.

[0044] The control device is used to control the first valve 14 to be turned on, and the second valve 15 to switch the metering pump 11 to communicate with the reagent bottle, and control the pressure component 12 to generate negative pressure to the metering pump 11, so that the reagent in the reagent bottle enters the metering pump 11. After the reagent in the reagent bottle is absorbed, the control device is also used to control the second valve 15 to switch the metering pump 11 to communicate with the liquid storage tank 13, and control the pressure component 12 to generate positive pressure to the metering pump 11, so that the reagent in the metering pump 11 is perfused into the liquid storage tank 13.

[0045] During this process, as described above, the detection device will detect the flow rate of the reagent in the metering pump 11, and when the flow rate of the reagent in the metering pump 11 is less than the preset flow rate, the fault information will be transmitted to the control device. The control device controls the display device to display a first pop-up window to remind the user to adjust the pressure component 12, so that the sample analyzer can automatically judge the fault, eliminate the fault in time, and improve the perfusion efficiency of the liquid storage tank 13.

[0046] In one embodiment, the liquid storage device 1 may further include a pressure relief component, and the liquid storage tank 13 may be connected to the pressure relief component via another valve. Then, during the process of perfusing the liquid storage tank 13 with reagent, the valve is turned on to connect the liquid storage tank 13 with the pressure relief component, and the pressure relief component relieves the pressure of the liquid storage tank 13 to avoid the pressure in the liquid storage tank 13 increasing with the perfusion of the reagent, thereby affecting the subsequent perfusion of the reagent, thereby improving the efficiency of the perfusion of the reagent into the liquid storage tank 13.

[0047] In summary, the sample analyzer provided in the embodiment of the present application responds to the target fault information that the liquid storage tank 13 of the liquid storage device 1 is not full through the detection device, and at the same time the control device controls the operation of the liquid storage device 1 based on the target fault information, and specifically can adjust the pressure component 12 in the liquid storage device 1, thereby solving the problem that manual troubleshooting is required when the existing instrument fails, resulting in low efficiency in fault elimination, improving the efficiency of fault troubleshooting and elimination in the sample analyzer, and improving the user experience of the sample analyzer.

[0048] The present application also provides a method for handling a sample analyzer failure, which is applied to the sample analyzer as described above. Figure 2 , Figure 2 1 is a flow chart of the first embodiment of the processing method of the present application. The processing method of the sample analyzer failure provided in the embodiment of the present application specifically includes the following steps: S1: Obtain target fault information.

[0049] When the detection device detects that the liquid storage volume of the liquid storage tank 13 is less than the preset liquid storage volume, the target fault information is transmitted to the control device, and the control device acquires the target fault information. The target fault is the fault that the liquid storage tank 13 is not filled fully.

[0050] S2: Determine whether there is a first fault in the fault list.

[0051] After the control device obtains the target fault information, it can further determine whether there is a first fault in the fault list, wherein the first fault is a pressure-related fault, and the fault list is a list formed based on at least one fault information detected by the detection device.

[0052] Specifically, the control device can classify different fault information in the fault list, for example, divide the fault information in the fault list into a first fault related to pressure and other faults not related to pressure, and then perform different elimination procedures for faults of different factors to improve the efficiency of eliminating fault information.

[0053] As mentioned above, the target fault information that causes the liquid storage tank 13 to be not fully filled may be caused by fault information such as the volume of the metering pump 11 being too small, the pressure provided by the pressure component 12 being too small, the float sensor in the liquid storage tank 13 failing, or the connecting pipe between the liquid storage tank 13 and the metering pump 11 being broken. During the operation of the detection device, it will detect and collect these fault information, and transmit the collected fault information to the control device. The control device forms a fault list with at least one fault information detected by the detection device.

[0054] In one embodiment, the control device may also display the generated fault list on the display device to facilitate user observation and improve the interaction capability between the sample analyzer and the user.

[0055] Further, in response to the presence of the first fault in the fault list, the control device may enter step S3 to obtain the current pressure value of the pressure component 12 .

[0056] In response to the fact that the first fault does not exist in the fault list, the control device enters step S4 and directly executes the normal fault elimination procedure to eliminate the fault information in the fault list.

[0057] S3: In response to the first fault in the fault list, the current pressure value of the pressure component 12 is obtained.

[0058] When the control device responds to the presence of the first fault in the fault list, that is, a pressure-related fault exists at this time, the control device may first obtain the current pressure value of the pressure component 12 to determine whether the pressure value provided by the pressure component 12 is abnormal, so as to perform subsequent elimination steps based on the pressure value in the liquid storage device 1.

[0059] S4: In response to the first fault not existing in the fault list, directly executing a normal fault elimination procedure to eliminate the fault information in the fault list.

[0060] When the control device responds that there is no first fault in the fault list, that is, the target fault information is not caused by a pressure-related fault, the control device can directly execute a normal fault elimination procedure to eliminate the fault information in the fault list.

[0061] Among them, the normal fault elimination procedure can be to adjust the operation of other components in the liquid storage device 1, or do not process it and wait for the liquid storage device 1 to alleviate and eliminate it by itself.

[0062] By first locating the fault to determine the factors causing the target fault information, the efficiency of fault detection can be improved, which can further improve the efficiency of fault elimination.

[0063] For further information, see Figure 3 , Figure 3 1 is a flow chart of the second embodiment of the processing method of the present application. After the control device determines in step S3 that there is a first fault in the fault list and obtains the current pressure value of the pressure component 12, the processing method further includes: S21: Determine whether the current pressure value is within a preset pressure range.

[0064] After the control device obtains the current pressure value of the pressure component 12, the control device may first compare the obtained current pressure value with the preset pressure range to determine whether the current pressure value of the pressure component 12 meets the requirement. The preset pressure range may be set according to the user's requirements, and this application does not impose any specific restrictions on this.

[0065] In response to the pressure value being within the preset pressure range, it can be considered that the pressure generated by the pressure component 12 meets the filling requirement, and the failure of the liquid storage tank 13 not being fully filled should be caused by other factors, then entering step S22.

[0066] In response to the pressure value not being within the preset pressure range, it can be determined that the pressure generated by the pressure component 12 does not meet the demand, and the pressure component 12 needs to be adjusted to eliminate the pressure-related fault, then entering steps S23-S24.

[0067] S22: In response to the current pressure value being within the preset pressure range, directly executing the normal fault elimination procedure to eliminate the fault information in the fault list.

[0068] As mentioned above, in response to the pressure value being within the preset pressure range, that is, the pressure generated by the pressure component 12 at this time does not exceed the abnormal range, the control device can determine that the pressure generated by the pressure component 12 at this time meets the demand and should be the target fault information caused by other factors. Therefore, the pressure component 12 can be adjusted without performing the normal fault elimination procedure, and the fault information in the fault list can be eliminated.

[0069] S23: In response to the current pressure value not being within the preset pressure range, determining the first fault as a second fault.

[0070] In response to the pressure value not being within the preset pressure range, the control device may determine that the pressure provided by the pressure component 12 at this time does not meet the demand, and the pressure component 12 needs to be adjusted to eliminate the fault, and the first fault is determined as the second fault, wherein the second fault is the first fault in which the pressure value is not within the preset pressure range.

[0071] S24: Eliminate the fault information in the fault list according to the preset fault priority, and in response to the fault information currently being eliminated being the second fault, prompt the user to adjust the pressure value generated by the pressure component 12.

[0072] After the control device determines the first fault as the second fault, the fault information in the fault list may be deleted according to the preset fault priority after the fault list is updated.

[0073] Among them, the fault information in the fault list includes multiple types, such as non-pressure-related faults, pressure-related faults (first faults), faults where the pressure value is not within the preset pressure range (second faults), etc., among which non-pressure-related faults will also include multiple device faults. The user can classify the multiple types of fault information into levels in advance, and after forming a preset fault priority, the control device eliminates the fault information in the fault list based on the preset fault priority.

[0074] As mentioned above, the elimination of the second fault requires adjustment of the pressure component 12. In response to the fault information currently being eliminated being the second fault, the control device obtains the current pressure value of the pressure component 12 and displays the current pressure value on the first interface of the display device to remind the user to adjust the pressure component 12 by adjusting the pressure valve to eliminate the second fault.

[0075] Furthermore, the control device may also generate warning information according to the current pressure value of the pressure component 12 , and display the warning information on the first interface to prompt the user to adjust the pressure component 12 .

[0076] In one embodiment, the first interface may only display the alarm information, or the first interface may display the alarm information and the current pressure value. The specific setting can be based on user needs, and this application does not impose any restrictions on this.

[0077] The pressure value on the first interface will be updated as the user adjusts it, thereby improving the interaction capability between the sample analyzer and the user.

[0078] For further information, see Figure 4 , Figure 41 is a flow chart of the third embodiment of the processing method of the present application. After the user adjusts the pressure component 12, the processing method provided in this embodiment also includes: S31: Obtaining the adjusted pressure value, and determining whether the adjusted pressure value is within a preset pressure range.

[0079] After adjusting the pressure component 12, the control device can further obtain the adjusted pressure value of the pressure component 12, and determine whether the adjusted pressure value is within a preset pressure range.

[0080] In response to the adjusted pressure value being within the preset pressure range, the process proceeds to step S32 ; in response to the adjusted pressure value not being within the preset pressure range, the process proceeds to step S33 .

[0081] S32: In response to the adjusted pressure value being within the preset pressure range, it is determined that the second fault is eliminated successfully, all second faults in the fault list are removed, and a normal fault elimination procedure is performed on other fault information in the fault list to eliminate the fault information in the fault list.

[0082] In response to the adjusted pressure value being within the preset pressure range, that is, the adjustment of the pressure component 12 is effective and the pressure value of the pressure component 12 has been restored to the required range, the control device determines that the second fault has been successfully eliminated, removes all second faults in the fault list, and updates the fault list. At the same time, a normal fault elimination procedure can be performed on other fault information in the fault list to eliminate the fault information in the fault list, so as to realize the automatic judgment and elimination of faults by the sample analyzer and improve the user experience.

[0083] S33: In response to the adjusted pressure value not being within the preset pressure range, determining that the second fault elimination fails.

[0084] In response to the adjusted pressure value not being within the preset pressure range, that is, the adjustment of the pressure component 12 does not work, and the pressure value of the pressure component 12 cannot be adjusted to the required range, there may be other fault information affecting the pressure value in the liquid storage device 1. The control device determines that the second fault elimination fails.

[0085] Please continue reading Figure 5 , Figure 5 1 is a flow chart of the fourth embodiment of the processing method of the present application. After the control device determines that the second fault has failed to be eliminated, the processing method provided in this embodiment further includes the following steps: S41: Determine whether there is fault information in the fault list that has not undergone the elimination procedure.

[0086] As mentioned above, the failure to eliminate the second fault may be due to abnormal pressure value in the liquid storage device 1 caused by other fault information. The control device first obtains all fault information in the fault list and determines whether there is any fault information in the fault list that has not undergone the elimination procedure.

[0087] In response to the presence of fault information that has not undergone the elimination procedure in the fault list, the process proceeds to step S42 ; in response to the absence of fault information that has not undergone the elimination procedure in the fault list, the process proceeds to step S43 .

[0088] S42: In response to the presence of fault information that has not undergone the elimination procedure in the fault list, the fault information that has not undergone the elimination procedure is eliminated.

[0089] In response to the presence of fault information that has not undergone an elimination procedure in the fault list, the control device may eliminate the fault information that has not undergone an elimination procedure in the fault list according to a preset fault priority.

[0090] Specifically, the control device may first determine whether the fault information currently being eliminated is the second fault. In response to the fault information currently being eliminated being the second fault, the control device returns to execute the step of obtaining the current pressure value of the pressure component 12, generates an alarm message based on the current pressure value of the pressure component 12, and displays the current pressure value and the alarm message, or the alarm message on the first interface of the display device to prompt the user to adjust the pressure component 12, which is step S24. The specific elimination process for the second fault is as described above and will not be repeated here.

[0091] In response to the fact that the fault information currently being eliminated is not the second fault, the control device directly executes the normal fault elimination process to eliminate the fault information in the fault list.

[0092] After all the fault information in the fault list is eliminated, the control device ends the elimination program.

[0093] S43: In response to the fact that there is no fault information that has not undergone the elimination process in the fault list, the elimination process is terminated.

[0094] Among them, if the control device responds that there is no fault information in the fault list that has not undergone the elimination procedure, that is, there is only a second fault that has failed to be eliminated in the fault list at this time, but the second fault cannot be eliminated by adjusting the pressure component 12, then the control device ends the elimination procedure to avoid executing the elimination procedure for the second fault again. If the elimination of the second fault fails again, the sample analyzer will fall into an endless loop of the elimination procedure, thereby improving the intelligence level of the sample analyzer in eliminating faults.

[0095] In one embodiment, after the control device responds to the absence of fault information in the fault list that has not undergone the elimination procedure and ends the elimination procedure, the control device can control the display device to display the second fault that failed to be eliminated to remind the user of the existence of the fault and facilitate the user to repair it in time.

[0096] In summary, in the method for handling sample analyzer faults provided by the present application, after the control device obtains the target fault information, it will first determine whether there is a first fault in the fault list, and perform an elimination procedure based on the first fault to eliminate the target fault information. Specifically, when there is a first fault in the response fault list, the current pressure value of the pressure component 12 is obtained and compared with the preset pressure range to determine and locate the fault factor, and different elimination procedures are performed for different types of fault information, thereby improving the efficiency of fault elimination, improving the orderliness of eliminating fault information in the sample analyzer, improving the practicality of the processing method provided by the present application, and enhancing the user experience.
