Description

Sample analyzer and activation method of electrode assembly thereof Technical Field

[0001] The present application relates to the field of in vitro diagnostic equipment, and in particular to a sample analyzer and a method for activating an electrode assembly in the sample analyzer. Background Art

[0002] A sample analyzer provided by the related art includes an electrolyte measurement module, which is a device for measuring the electrolyte content in samples such as serum or urine. The electrolyte measurement module includes a detection container and an electrode assembly, which is used to perform electrolyte measurement on the test liquid flowing out of the detection container. The electrode assembly includes at least one ion-selective electrode (i.e., ISE electrode), which is used to perform electrolyte measurement on the sample. The electrode assembly usually needs to be activated before being unsealed and used.

[0003] In the related art, the activation method of the electrode assembly is: before the electrode assembly is put on the machine, the electrode assembly is manually immersed in a high-concentration salt solution for several hours or overnight. In specific applications, this activation method has the following shortcomings: 1) The activation process is cumbersome, and the operator's understanding may be biased, and misoperation is inevitable. In particular, the immersion time is difficult to control. If the immersion time is too short, the electrode activation effect is not good. If the machine is directly tested, the calibration slope will be low or the potential drift will occur, resulting in low electrolyte measurement results. If the immersion time is too long, the electrode membrane of the electrode assembly may be damaged, thereby reducing the performance of the electrode assembly. 2) It takes a long time. As a common consumable of the electrolyte measurement module, if the electrode assembly cannot be replaced in time once a fault occurs, the efficiency of medical diagnosis will be reduced, the issuance of the calibration report will be delayed, and it is easy to cause delays in the patient's condition. 3) The activation effect of the electrode assembly after water matrix activation is not ideal, which will affect the performance of the electrode assembly.

DETAILED DESCRIPTION

[0094] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0095] It should be noted that the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0096] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0097] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0098] There are two main reasons why the electrode assembly needs to be activated: (1) When an unactivated electrode assembly is first used, the aqueous solution generally flows through the measurement channel of the electrode assembly. Since the surface of the measurement channel is hydrophobic, it is easier for bubbles to form in the measurement channel of the electrode assembly, resulting in a sudden change in the measured electrode potential signal and unstable measurement results. Therefore, the measurement channel of the electrode assembly needs to be activated. (2) Since the unactivated electrode membrane is stored in a dry environment for a long time, there is a concentration difference between the internal filling liquid in the electrode membrane and the external air. The electrode membrane response is in an unbalanced state, and the resistance of the electrode membrane will be high. When the electrode membrane material is immersed in a certain salt solution, as the immersion time increases, the internal resistance of the electrode membrane will gradually decrease and gradually reach stability. During the activation process of the ion-selective electrode, the electrode membrane contacts the solution, and the target ions diffuse in the electrode membrane. It is considered to be divided into two steps. The first step is from the solution body to the surface of the electrode assembly, and the second step is the diffusion from the surface of the electrode assembly to the electrode membrane. Assuming that when the electrode membrane contacts the solution, the first step is very fast and the second step is a slow process, then the activation process is mainly determined by the second step. The diffusion of target ions into the electrode membrane is equivalent to charging the above circuit. The thickness of the electrode membrane is determined by the time required for activation of the electrode assembly. The thicker the electrode membrane, the longer the activation process.

[0099] Example 1:

[0100] As shown in Figures 1 to 5, the sample analyzer 10 provided in the first embodiment of the present application includes an electrode assembly 100 and a detection container 200. The electrode assembly 100 is used to measure target ions (i.e., electrolyte measurement, which primarily measures the concentration of target ions in the test liquid) in a test liquid flowing out of the detection container 200. The test liquid at least contains a sample. Optionally, the electrode assembly 100 can be activated using an activation liquid, wherein the activation liquid is formed from at least a first liquid.

[0101] In one embodiment, the first liquid is one of a serum control, a plasma control, a serum sample, a plasma sample, and a saline solution, wherein the saline solution contains at least protein. Activating the electrode assembly 100 using any of the serum control, plasma control, serum sample, plasma sample, and a saline solution containing at least protein results in more complete activation, better activation effects, and shorter activation times than activating the electrode assembly 100 using an aqueous matrix solution. This embodiment optimizes and limits the first liquid to ensure effective activation of the electrode assembly 100.

[0102] In one embodiment, the detection container 200 has an inner cavity and a liquid discharge port connected to the inner cavity. The liquid discharge port is used to allow the test liquid to flow from the inner cavity to the electrode assembly 100. The inner cavity provides a storage space for the sample and the test liquid.

[0103] As an embodiment, the sample analyzer 10 further includes a first liquid dispensing device 700, which is used to dispense a first liquid into the inner cavity of the detection container 200, so as to activate the electrode assembly 100 with the first liquid. Furthermore, the first liquid dispensing device 700 is also used to dispense a sample into the inner cavity of the detection container 200.

[0104] It can be understood that dispensing the sample and the first liquid into the detection container 200 can be performed by the same dispensing device or by different dispensing devices.

[0105] Optionally, the first liquid dispensing device 700 includes a first sub-liquid dispensing device 701 and a second sub-liquid dispensing device 702, wherein the first sub-liquid dispensing device 701 is used to dispense the sample into the inner cavity of the detection container 200, and the second sub-liquid dispensing device 702 is used to dispense the first liquid into the inner cavity of the detection container 200.

[0106] In other words, the first sub-liquid dispensing device 701 is primarily used to achieve quantitative sample distribution. For example, the first sub-liquid dispensing device 701 injects the sample into the detection container 200 through a dispensing method. The second sub-liquid dispensing device 702 is used to distribute the first liquid into the inner cavity of the detection container 200. The first liquid is used to activate the electrode assembly 100.

[0107] As an embodiment, the sample analyzer 10 further includes a drain device 300, which is connected to the drain port via the electrode assembly 100. The drain device 300 is configured to sequentially drain the test liquid or activation liquid in the detection container 200 through the drain port and the electrode assembly 100. The activation liquid includes at least a first liquid. The drain device 300 is primarily configured to provide a driving force for the liquid in the detection container 200 to flow out of the drain port and through the electrode assembly 100. In other words, the drain device 300 is connected to the electrode assembly 100 to drain the liquid flowing through the electrode assembly 100.

[0108] As an embodiment, the sample analyzer 10 further includes a controller, which is electrically connected to at least one of the electrode assembly 100 , the first sample dispensing device 400 , the liquid discharge device 300 , and the first liquid dispensing device 700 .

[0109] As an embodiment, the controller is configured to execute an activation process to activate the electrode assembly 100, and execute an electrolyte measurement process to measure the sample to obtain an electrolyte measurement result. The activation process includes multiple activation cycles, and the electrolyte measurement process includes at least one electrolyte measurement cycle. This embodiment configures the activation process in the controller so that the activation of the electrode assembly 100 can be automatically performed under the control of the controller. The automatic activation scheme has the advantages of simple operation and short time. In addition, the automatic activation can ensure the consistency of the activation effect of the electrode assembly 100 and avoid the influence of human factors caused by different operators.

[0110] As an embodiment, during a single activation cycle, the controller is configured to: control the first liquid dispensing device 700 to dispense the first liquid into the inner cavity of the detection container 200 to form an activation liquid; and control the liquid discharge device 300 to drive the activation liquid in the detection container 200 to flow through the liquid discharge port and out of the electrode assembly 100. The activation process primarily involves allowing the activation liquid to flow through the electrode assembly 100 and ensure that the electrode assembly 100 is fully in contact with the activation liquid.

[0111] As one embodiment, during a single electrolyte measurement cycle, the controller is configured to: control the first liquid dispensing device 700 to dispense a sample into the inner cavity of the detection container 200 to form a test liquid; control the liquid discharge device 300 to drive the test liquid in the inner cavity of the detection container 200 to flow sequentially through the liquid discharge port and the activated electrode assembly 100; and obtain an electrolyte measurement result of the sample based on at least a first electrical parameter of the electrode assembly 100 as the test liquid flows through the electrode assembly 100. In this embodiment, using the activated electrode assembly 100 for electrolyte measurement helps ensure the accuracy of the measurement results.

[0112] As one embodiment, the liquid drainage device 300 includes a liquid drainage power unit 310 and a waste liquid channel 320. The liquid drainage power unit 310 is used to drive the liquid in the inner cavity of the detection container 200 to flow through the liquid drainage port, the electrode assembly 100, and then be discharged into the waste liquid channel 320. The liquid drainage power unit 310 is primarily used to provide driving force for the liquid in the detection container 200 to flow out of the liquid drainage port and through the electrode assembly 100. The waste liquid channel 320 is connected to a waste liquid collection container and is used to discharge the liquid discharged by the liquid drainage power unit 310 into the waste liquid collection container.

[0113] In one embodiment, the sample is serum, plasma, urine, or other body fluid. After being collected from a patient, the sample is stored in a sample container. The first sample dispensing device 400 is used to aspirate the sample from the sample container and dispense at least a portion of the aspirated sample into the testing container 200. The sample container is provided with an identification code, which includes at least one of a barcode, a QR code, and a radio frequency code.

[0114] As an embodiment, the duration of the activation liquid flowing through the electrode assembly 100 in a single activation cycle is longer than the duration of the test liquid flowing through the electrode assembly 100 in a single electrolyte measurement cycle. This embodiment can shorten the activation process duration of the electrode assembly 100 by extending the contact time between the activation liquid and the electrode assembly 100.

[0115] In one embodiment, the controller is further configured to: during a single activation cycle, control the drain device 300 to drive the activated liquid in the inner cavity of the detection container 200 to flow through the electrode assembly 100 at a speed that is less than the speed at which the drain device 300 drives the test liquid in the detection container 200 to flow through the electrode assembly 100 during a single electrolyte measurement cycle. That is, the controller is further configured to control the drain device 300 to drive the activated liquid in the inner cavity of the detection container 200 to flow through the electrode assembly 100 at a first speed during a single activation cycle, and to control the drain device 300 to drive the test liquid in the inner cavity of the detection container 200 to flow through the electrode assembly 100 at a second speed during a single electrolyte measurement cycle, wherein the first speed is less than the second speed. This embodiment primarily uses speed control to ensure that the duration of the activated liquid flowing through the electrode assembly 100 during the activation cycle is greater than the duration of the test liquid flowing through the electrode assembly 100 during the electrolyte measurement cycle.

[0116] Of course, in specific applications, the method for making the duration of the activation liquid flowing through the electrode assembly 100 during the activation cycle longer than the duration of the liquid to be tested flowing through the electrode assembly 100 during the electrolyte measurement cycle is not limited to the above-mentioned scheme of speed control. For example, as an alternative embodiment, intermittent control can be used during the activation cycle to achieve the purpose of making the duration of the activation liquid flowing through the electrode assembly 100 during the activation cycle longer than the duration of the liquid to be tested flowing through the electrode assembly 100 during the electrolyte measurement cycle. Specifically, in this alternative embodiment, the controller is further configured to: during a single activation cycle, control the drain device 300 to drive the activation liquid in the inner cavity of the detection container 200 to flow through the electrode assembly 100 in an intermittent driving manner; and during a single electrolyte measurement cycle, control the drain device 300 to drive the liquid to be tested in the inner cavity of the detection container 200 to flow through the electrode assembly 100 in a continuous driving manner.

[0117] As an embodiment, the electrode assembly 100 includes at least one ion selective electrode 110 and a reference electrode 120, and the at least one ion selective electrode 110 includes at least one of a sodium ion selective electrode 110, a chloride ion selective electrode 110, and a potassium ion selective electrode 110. The ion selective electrode 110 (which can be referred to as an ISE electrode, ISE is the abbreviation of Ion Selective Electrode) is mainly composed of an ion selective membrane (which can be referred to as a "selective membrane"), an internal electrolyte solution, and an electrode silver rod composed of silver or silver chloride. In this embodiment, the ion selective electrode 110 and the reference electrode 120 are arranged side by side, and the electrical parameters of the ion selective electrode 110 and the reference electrode 120 are obtained by the liquid to be measured flowing through the ion selective electrode 110 and the reference electrode 120 in sequence. Of course, in specific applications, the arrangement of the electrode assembly 100 is not limited to this.

[0118] As an embodiment, the electrode assembly 100 includes a reference electrode 120, a sodium ion selective electrode 110, a chloride ion selective electrode 110, and a potassium ion selective electrode 110. In this embodiment, the sodium ion concentration, the chloride ion concentration, and the potassium ion concentration of the sample can be measured.

[0119] As an embodiment, the electrode assembly 100 further includes a measurement channel, wherein the liquid discharge port is connected to the measurement channel. The reference electrode 120 and the ion selective electrode 110 are at least partially disposed within the measurement channel, so that liquid flowing through the measurement channel can contact the reference electrode 120 and the ion selective electrode 110.

[0120] As one embodiment, the sample analyzer 10 further includes a diluent dispensing device 500 for dispensing a diluent into the inner cavity of the detection container 200. The test liquid is prepared by diluting the sample with the diluent, and the activating liquid is prepared by diluting the first liquid with the diluent. In this embodiment, when performing an electrolyte measurement, the sample is first diluted with the diluent to obtain the test liquid. This indirect method is used to measure the target ion concentration in the sample, which has the beneficial effects of reducing sample consumption and reducing the impact of substances such as proteins and lipids in the sample on the measurement results.

[0121] In one embodiment, the test liquid is prepared by diluting the sample with a diluent at a first dilution ratio; the activation liquid is prepared by diluting the first liquid with a diluent at a second dilution ratio; the second dilution ratio is lower than the first dilution ratio. Using a higher concentration of activation liquid to activate the electrode assembly 100 can shorten the dilution and activation times.

[0122] As an embodiment, the controller is further configured to: during at least one of the activation cycles, control the discharge device 300 to drive the activation liquid in the inner cavity of the detection container 200 to flow through the electrode assembly 100, and obtain a second electrical parameter of the electrode assembly 100; after the activation process is completed, determine whether the second electrical parameter meets the first preset condition; if so, determine that the activation of the electrode assembly 100 is successful; if not, determine that the activation of the electrode assembly 100 has failed. After the activation process is completed, the diagnostic process is automatically entered to determine whether the activation is successful. In this embodiment, based on the second electrical parameter of the electrode assembly 100 collected during the activation process, whether the activation is successful is determined, thereby ensuring the stability and reliability of the activation effect of the electrode assembly 100.

[0123] It is understood that, in this specification, whether activation is successful includes at least whether activation of the electrode assembly 100 is successful, and activation failure includes at least activation failure of the electrode assembly 100. Similarly, activation success includes at least successful activation of the electrode assembly 100. As an embodiment, the activation process includes a first preset number of activation cycles, that is, the number of cycles corresponding to the multiple activation cycles is the first preset number; the number of the multiple activation cycles is the first preset number, and the number of the at least one activation cycle is the second preset number, which is less than the first preset number.

[0124] After the activation process is completed, determining whether the second electrical parameter meets the first preset condition includes: after completing the first preset number of activation cycles, measuring the second electrical parameter based on the second preset number of activation cycles, and determining whether the first preset condition is met; wherein the second preset number is less than the first preset number. This embodiment uses whether the first preset number of activation cycles has been completed as the basis for determining whether to stop the activation process, which helps prevent the undesirable phenomenon of the activation process looping out of control. In addition, this embodiment uses the second electrical parameter of the second preset number of activation cycles that is less than or equal to the first preset number as the basis for diagnosing the electrode assembly 100.

[0125] In one embodiment, the second preset number is less than the first preset number, i.e., the second electrical parameters of a second preset number of activation cycles, which are less than or equal to the first preset number, are used as the basis for diagnosing the electrode assembly 100. This helps reduce the amount of computation required. In one embodiment, determining whether the first preset condition is satisfied based on the second electrical parameters measured during the second preset number of activation cycles includes determining whether the first preset condition is satisfied based on the second electrical parameters measured during the last second preset number of activation cycles in the activation process. Optionally, the last consecutive activation cycles in the activation process are used as the second preset number of activation cycles.

[0126] The second electrical parameter measured based on the activation cycle at the end of the activation process will be more stable than the second electrical parameter measured at the activation cycle at the beginning of the activation process. In this embodiment, the second electrical parameter measured at the end of the second preset number of activation cycles is used as the basis for judging whether the activation is successful, which is beneficial for ensuring the reliability of the judgment result and reducing the amount of calculation. The second preset number of activation cycles at the end of the activation process is the last second preset number of activation cycles in the activation process. For example, if the activation process includes 100 activation cycles and the second preset number is 20, the second electrical parameter measured at the end of the second preset number of activation cycles in the activation process is the second electrical parameter measured at the last 20 activation cycles.

[0127] As an embodiment, the sample analyzer 10 also includes an internal standard liquid dispensing device 600, which is used to dispense internal standard liquid into the detection container 200; during the electrolyte determination cycle, the controller is further configured to: obtain a first electrical parameter of the electrode assembly 100 while controlling the drainage device 300 to drive the liquid to be tested in the detection container 200 to flow through the electrode assembly 100; control the internal standard liquid dispensing device 600 to dispense internal standard liquid into the detection container 200, control the drainage device 300 to drive the reference liquid in the detection container 200 containing at least the internal standard liquid to flow through the drainage port and the electrode assembly 100 in sequence, and obtain a fourth electrical parameter of the electrode assembly 100 while controlling the drainage device 300 to drive the reference liquid in the detection container 200 to flow through the electrode assembly 100; and obtain the electrolyte determination result of the sample based on the difference between the first electrical parameter and the fourth electrical parameter. That is, the controller executes at least a first electrical parameter of the electrode assembly when the test liquid flows through the electrode assembly to obtain an electrolyte measurement result of the sample, including: obtaining the electrolyte measurement result of the sample based on the difference between the first electrical parameter and the fourth electrical parameter. In this embodiment, the electrical parameters obtained during the electrolyte measurement are calculated based on the electrical parameters of the electrode assembly 100 when the test liquid and the reference liquid flow through the electrode assembly 100, respectively. This can make the electrolyte measurement result of the sample more accurate and the measurement speed faster.

[0128] As an embodiment, within a single activation cycle, the controller is configured to: control the internal standard liquid dispensing device 600 to distribute the internal standard liquid into the detection container 200, control the drainage device 300 to drive the reference liquid containing at least the internal standard liquid in the detection container 200 to flow through the drainage port and the electrode assembly 100 in sequence; in the process of controlling the drainage device 300 to drive the reference liquid in the detection container 200 to flow through the electrode assembly 100, obtain the third electrical parameter of the electrode assembly 100, the third electrical parameter is the electric potential; the first electric potential change parameter is the electric potential difference change parameter between the second electric parameter and the third electric parameter. In this embodiment, the electrical parameters obtained during the activation process are calculated based on the electrical parameters of the electrode assembly 100 when the activation liquid and the reference liquid flow through the electrode assembly 100 respectively. This can correspond to the data analysis method of the electrolyte determination on the one hand, and on the other hand, it can make the activation effect of the electrode assembly 100 more reliable and the activation speed faster.

[0129] In one embodiment, the first potential variation parameter is the coefficient of variation CV of the potential difference between the second electrical parameter and the third electrical parameter, and the first preset condition includes the coefficient of variation of the potential difference between the second electrical parameter and the third electrical parameter being within a fourth preset range. In this embodiment, the coefficient of variation CV of the potential difference is used as the basis for determining whether activation is successful. The coefficient of variation CV of the potential difference can be calculated from the standard deviation SD of the potential difference. The calculation formulas for CV and SD are as follows:

[0130] Among them, E S-B is the potential difference between the activation liquid flowing through the electrode assembly 100 and the reference liquid flowing through the electrode assembly 100, The average value of the potential difference between the activation liquid flowing through the electrode assembly 100 and the reference liquid flowing through the electrode assembly 100 is measured for the second preset number of activation cycles. Of course, in specific applications, the coefficient of variation (CV) of the potential difference serves as the basis for determining whether the activation is successful. For example, as an alternative embodiment, the standard deviation (CD) of the potential difference may also be used as the basis for determining whether the activation is successful. That is, the first potential variation parameter is the standard deviation of the potential difference between the second electrical parameter and the third electrical parameter, and the first preset condition includes the standard deviation of the potential difference between the second electrical parameter and the third electrical parameter being within a third preset range.

[0131] As an embodiment, the controller is further configured to: after completing the first preset number of activation cycles, if it is determined that the activation has failed, output a warning signal of activation failure and / or re-execute the activation process. That is, if the activation of the electrode assembly 100 fails, output a warning signal of activation failure and / or re-execute the activation process. As an embodiment, the first preset number and the second preset number are fixed values ​​and cannot be adjusted manually, that is, the number of activation cycles of the activation process cannot be adjusted manually. Of course, in a specific application, as an alternative embodiment, the first preset number and the second preset number can also be set to a manually adjustable manner. Specifically, in this alternative embodiment, the sample analyzer 10 also includes a human-computer interaction device, and the controller is further configured to: adjust the first preset number and / or the second preset number according to the instructions input by the operator through the human-computer interaction device.

[0132] As an embodiment, the sample analyzer 10 pre-stores at least one of the following third preset conditions: the sample analyzer 10 is installed and started for a first preset time, the electrode assembly 100 is replaced, and the sample analyzer 10 is installed and started for a second preset time, and a third preset time has passed since the last activation process was executed; the continuous time or duration during which the electrode assembly 100 does not perform electrolyte measurement reaches a fourth preset time; the preset time point of the preset activation cycle is reached; information that the electrode assembly 100 needs to be activated is obtained based on instructions input by the operator through the human-computer interaction device; the controller is further configured to: execute the activation process when any of the third preset conditions is met.

[0133] In one embodiment, the sample analyzer 10 further includes a reagent dispensing device, a second sample dispensing device, and at least one optical measurement device. The second sample dispensing device is configured to draw a sample from a sample container and dispense it into a reaction container. The reagent dispensing device is configured to draw a reagent from a reagent container and dispense it into the reaction container. The optical measurement device is configured to optically measure a reaction solution composed of at least the sample and the reagent. The at least one optical measurement device includes at least one of a first optical measurement component, a second optical measurement component, and a third optical measurement component. The first optical measurement component is configured to measure immune-related parameters of the reaction solution, the second optical measurement component is configured to measure biochemical-related parameters of the reaction solution, and the third optical measurement component is configured to measure coagulation-related parameters of the reaction solution. The second sample dispensing device and the first sample dispensing device 400 may be the same device or two independent devices. In this embodiment, in addition to integrating an electrolyte measurement function, the sample analyzer 10 also integrates at least one of a biochemical measurement function, an immunoassay function, and a coagulation measurement function. That is, the electrolyte measurement module can be integrated into a biochemical analyzer, an immunoassay analyzer, or a coagulation analyzer. This facilitates the diversification of the functions of the sample analyzer 10. Of course, in a specific application, as an alternative implementation, the sample analyzer 10 may also have only the electrolyte measurement function, that is, the sample analyzer 10 may be a standalone electrolyte measurement device.

[0164] Optionally, judging whether the second preset condition is satisfied based on the second electrical parameter includes: obtaining a second potential change parameter based on the second electrical parameter in a third consecutive preset number of activation cycles, and judging whether the second preset condition is satisfied based on the second potential change parameter.

[0165] In the above scheme, internal standard solution is used when performing the activation process and the electrolyte determination process, and the judgment of whether to terminate the activation process in advance is also based on the potential difference between the activation liquid and the reference solution flowing through the electrode assembly 100. Of course, in specific applications, as an alternative embodiment, internal standard solution can also be used for judgment. In this alternative embodiment, the second preset condition includes one of the following conditions: in three consecutive preset number of activation cycles, the standard deviation of the potential of the electrode assembly 100 is within the fifth preset range; in the third preset number of activation cycles, the drift of the potential of the electrode assembly 100 is within the sixth preset range; in the third preset number of activation cycles, the deviation of the potential of the electrode assembly 100 relative to the mean is within the seventh preset range; in the third preset number of activation cycles, the coefficient of variation of the potential of the electrode assembly 100 is within the eighth preset range.
