At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0031] Electrostatic interference (ESI) can affect every stage of the testing process in a chemiluminescence immunoassay analyzer. Current ESI monitoring methods have the following shortcomings: 1. Defective instrument ESI shielding design: Traditional designs use a grounded metal casing (a common design), but this fails to eliminate ESI accumulation in internal components. 2. Lack of ESI monitoring: It cannot monitor for ESI abnormalities in each testing step. 3. Lack of dynamic control: It is not linked to real-time ESI monitoring, cannot be activated on demand, consumes high energy, and may interfere with detection.

[0032] To address the aforementioned issues, this application provides an immunoassay analyzer, comprising a robotic arm, multiple target functional areas, and a processor. The robotic arm is used to grasp reaction cups and transfer them to the multiple target functional areas to perform corresponding target functions. At least one of the robotic arm and the multiple target functional areas is equipped with an electrostatic sensor. The processor is used to acquire the electrostatic voltage value detected by the electrostatic sensor and determine whether electrostatic interference exists in the reaction cup based on the electrostatic voltage value.

[0033] The immunoassay analyzer provided in the embodiments of this application is described below with reference to the accompanying drawings.

[0034] Figure 1 An immunoassay analyzer 100 provided in an embodiment of this application is shown, including a robotic arm 10, multiple target functional areas 20 and a processor 30, which are described in detail below.

[0035] The robotic arm 10 is used to grasp the reaction cup 40 and transfer it to multiple target functional areas 20 to complete the corresponding target functions.

[0036] Specifically, in the immunoassay analyzer 100, the robotic arm 10 is the core execution component, which achieves precise sample and reagent processing, accurate control of the reaction process, and collaborative operation with multiple target functional areas 20 through automated operation. In the specific implementation process, the robotic arm 10 is used to grasp reaction cups 40 and transfer them to multiple target functional areas 20 to complete the corresponding target functions. At least one of the robotic arm 10 and multiple target functional areas 20 is equipped with an electrostatic sensor 50, which is used to detect the electrostatic voltage value of the reaction cups 40 so that the processor 30 can determine whether electrostatic interference exists in the reaction cups 40. The electrostatic sensor 50 on the robotic arm 10 is not shown.

[0037] For example, robotic arm 10 transfers reaction cup 40 from the sample application area to the incubation area, maintaining specific temperature and humidity and promoting antigen-antibody binding reactions. In a chemiluminescence immunoassay analyzer, robotic arm 10 transfers reaction cup 40 to the magnetic separation area, where magnetic particles are adsorbed by a magnetic field, and the washing needle is controlled to repeatedly inject / remove washing solution to remove free substances and reduce background noise. Robotic arm 10 also transfers reaction cup 40 to the photomultiplier tube, ensuring consistent light signal acquisition positions and improving data reliability.

[0038] The processor 30 is used to acquire the electrostatic voltage value detected by the electrostatic sensor 50 and to determine whether there is electrostatic interference in the reaction cup 40 based on the electrostatic voltage value.

[0039] Specifically, the processor 30 determines whether electrostatic interference exists in the reaction cup 40 based on the electrostatic voltage value detected by the electrostatic sensor 50. This can be done by comparing the detected electrostatic voltage value with a preset voltage threshold. If the detected electrostatic voltage value is greater than the voltage threshold, it is determined that electrostatic interference exists in the reaction cup 40; otherwise, it is determined that electrostatic interference does not exist in the reaction cup 40.

[0040] In this embodiment, since the robotic arm 10 and at least one of the multiple target functional areas 20 are equipped with an electrostatic sensor 50, the electrostatic conditions in different areas of the immunoassay analyzer 100 can be monitored, and the presence of electrostatic interference in the reaction cup 40 can be determined in a timely manner. This facilitates the timely resolution of electrostatic interference issues and avoids false negatives or false positives in the detection results of the immunoassay analyzer 100.

[0041] In some embodiments, multiple target functional areas 20 include a cup dropping mechanism, a cup guiding mechanism, an incubation tray, and a photon detection area. An electrostatic sensor 50 provided in the cup dropping mechanism is used to monitor whether there is electrostatic interference in the reaction cup 40 stored and released by the cup dropping mechanism. An electrostatic sensor 50 provided in the cup guiding mechanism is used to monitor whether there is electrostatic interference in the reaction cup 40 guided by the cup guiding mechanism. An electrostatic sensor 50 provided in the incubation tray is used to monitor whether there is electrostatic interference in the reaction cup 40 undergoing incubation. An electrostatic sensor 50 provided in the photon detection area is used to monitor whether there is electrostatic interference in the reaction cup 40 undergoing photon detection.

[0042] Specifically, the drop-cup mechanism stores multiple reaction cups 40. Upon receiving a command, it releases one of the reaction cups 40 to the guide cup mechanism, which guides the released reaction cup 40 to the target position so that the robotic arm 10 can grasp it more effectively. Through the coordinated work of the drop-cup mechanism and the guide cup mechanism, the reaction cup 40 is ensured to enter the subsequent testing process accurately and stably. The drop-cup mechanism is equipped with an electrostatic sensor 50 to monitor whether there is electrostatic interference in the reaction cups 40 stored and released by the drop-cup mechanism. The guide cup mechanism is equipped with an electrostatic sensor 50 to monitor whether there is electrostatic interference in the reaction cups 40 guided by the guide cup mechanism. This is to determine whether the selected new reaction cups are subject to electrostatic interference before entering the testing process, starting electrostatic monitoring from the source, identifying abnormal reaction cups in advance, and ensuring that subsequent processes are not affected by electrostatic interference. The robotic arm 10 grasps the reaction cup 40 containing the sample and reagent to be tested and places it into the incubation tray for incubation. The incubation tray is equipped with an electrostatic sensor 50 to detect whether there is electrostatic interference in the reaction cup 40 containing the sample and reagent for incubation. After different testing stages, the robotic arm 10 picks up the reaction cup 40 and places it in the photon detection area. The electrostatic sensor 50 set in the photon detection area is used to monitor whether there is electrostatic interference in the reaction cup 40 that is being tested for photon.

[0043] For example, an electrostatic sensor 50 is installed 5 cm below the cup dropping mechanism or the cup guiding mechanism to detect whether there is electrostatic interference in the reaction cup 40 being used. An electrostatic sensor 50 is installed below the incubation tray to monitor whether there is electrostatic interference in the reaction cup 40 being incubated in real time. An electrostatic sensor 50 is installed below the photon detection area to monitor whether there is electrostatic interference in the reaction cup 40 being detected in real time.

[0044] In this embodiment, electrostatic sensors installed in different target functional areas are used to monitor whether there is electrostatic interference in the reaction cup when the corresponding target function is implemented in the target functional area, thereby achieving accurate electrostatic monitoring.

[0045] In some embodiments, an electrostatic sensor 50 disposed above the gripping position of the robotic arm 10 is used to monitor whether there is electrostatic interference in the reaction cup 40 gripped by the robotic arm 10.

[0046] Specifically, considering that during the testing process of the immunoassay analyzer 100, the reaction cup 40 will be transferred to different target functional areas 20 for operations such as adding samples and reagents, in order to identify whether there is a risk of electrostatic interference in each testing step of the reaction cup 40 during the transfer process of the robotic arm 10 grasping the reaction cup 40, an electrostatic sensor 50 is set above the grasping position of the robotic arm 10. The grasping position is the set of target positions and postures reached by the end effector of the robotic arm 10 when grasping the reaction cup. The electrostatic state of the reaction cup 40 is monitored in real time in a non-contact manner, and precise monitoring is performed along the transfer path of the reaction cup 40.

[0047] In some embodiments, the processor 30 determines whether electrostatic interference exists in the reaction cup 40 based on the electrostatic voltage value, including: determining whether the electrostatic voltage value is greater than a preset voltage threshold; if it is greater than the voltage threshold, then determining that electrostatic interference exists in the reaction cup 40; otherwise, determining that electrostatic interference does not exist in the reaction cup 40.

[0048] Specifically, the preset voltage threshold is 500V. The system checks if the electrostatic voltage value is greater than 500V. If it is, the reaction vessel 40 is considered to have electrostatic interference; otherwise, the reaction vessel 40 is considered to have no electrostatic interference. The preset voltage threshold can be customized according to different immunoassay analyzers 100.

[0049] In some embodiments, the processor 30 determines whether electrostatic interference exists in the reaction cup 40 based on the electrostatic voltage value, including: determining whether the electrostatic voltage value is greater than a preset voltage threshold; if the electrostatic voltage value is greater than the voltage threshold at least twice within a preset time, then it is determined that electrostatic interference exists in the reaction cup 40, and an electrostatic interference alarm signal is issued.

[0050] Specifically, if the electrostatic voltage value is greater than 500V at least twice within a preset time, it is determined that electrostatic interference exists in the reaction vessel 40, and an electrostatic interference alarm signal is issued. The preset time can be 1 minute, or it can be set by the individual immunoassay analyzer 100.

[0051] In this embodiment of the application, if the electrostatic voltage value is greater than the voltage threshold at least twice within a preset time, it is determined that there is electrostatic interference in the reaction cup 40, which can eliminate the influence of instantaneous interference.

[0052] In some embodiments, the processor 30 is also configured to: if electrostatic interference exists in the reaction cup 40, send a command to the ion fan to activate the ion fan to release positive and negative ions to eliminate the electrostatic interference in the reaction cup 40.

[0053] Specifically, if electrostatic interference exists in the reaction vessel 40, the processor 30 sends a command to the ion fan to promptly activate the ion fan and release positive and negative ions to eliminate the electrostatic interference in the reaction vessel 40 and reduce airflow disturbance. The ion fan's pulse duration is 0.5 seconds by default, but can be customized according to different immunoassay analyzers 100.

[0054] In some embodiments, multiple target functional areas 20 include a photon detection area, which is equipped with an electrostatic sensor 50. The processor 30 is also used to: after the ion fan has run for a preset pulse time, acquire the electrostatic voltage value detected by the electrostatic sensor 50 in the photon detection area, and determine whether there is electrostatic interference in the reaction cup 40 based on the electrostatic voltage value. If there is electrostatic interference, issue an alarm signal to remind the user to retest the sample.

[0055] Specifically, after the ion fan runs for a preset pulse time, it stops working, indicating that the static electricity removal process is complete. The static voltage value detected by the static electricity sensor 50 in the photon detection area is obtained, and the presence of static interference in the reaction cup 40 is determined based on the static voltage value. If static interference is present, the ion fan will not be restarted for static electricity removal to avoid affecting the inspection efficiency of the next sample. Instead, an alarm signal will be issued to remind the user to retest the sample, indicating that the test result has static interference and the user needs to retest the sample, thus reducing the probability of abnormal results.

[0056] In some embodiments, the following scenarios may occur during the testing process: Scenario 1: When testing 10 samples consecutively using the immunoassay analyzer 100, at least twice within a preset time, the electrostatic voltage value exceeds 500V, triggering an electrostatic interference alarm signal; Scenario 2: When testing 10 samples consecutively using the immunoassay analyzer 100, an alarm prompting the user to retest the samples is issued; Scenario 3: Both scenarios 1 and 2 occur. If any of these scenarios occur, it indicates a problem with the immunoassay analyzer 100, and testing cannot continue. Continuing testing would only waste reagents and delay the detection time. The immunoassay analyzer 100 needs to stop the detection process, and the user should contact the manufacturer for repair. The number of consecutive alarms can be customized for different immunoassay analyzers 100.

[0057] The immunoassay analyzer 100 of this application embodiment can detect the static electricity status of various internal regions, promptly identify static electricity anomalies, and activate an ion fan for static elimination to remove the influence of static electricity and reduce the risk of false negatives and false positives in clinical diagnosis. The full-process monitoring of the immunoassay analyzer 100 includes monitoring the reaction cup 40 used, and whether static interference exists in the testing process and the final photon detection area. Simultaneously, by dynamically monitoring the static voltage in real time and comparing it with a voltage threshold, the ion fan is activated promptly to resolve static interference issues and avoid false negatives or false positives in the test results. Furthermore, to avoid problems with the ion fan's effectiveness, a final monitoring step is added in the photon detection area to promptly identify abnormal results caused by static interference and alert the user.

The immunoassay analyzer 100 includes a robotic arm 10 and multiple target functional areas 20. The robotic arm 10 is used to grasp reaction cups 40 and transfer them to the multiple target functional areas 20 to complete the corresponding target functions. At least one of the robotic arm 10 and the multiple target functional areas 20 is provided with an electrostatic sensor 50. The electrostatic monitoring method includes step S10, which is described in detail below.

[0059] Step S10: Obtain the electrostatic voltage value detected by the electrostatic sensor 50, and determine whether there is electrostatic interference in the reaction cup 40 based on the electrostatic voltage value.

[0060] Specifically, the presence of electrostatic interference in the reaction cup 40 is determined based on the electrostatic voltage value detected by the electrostatic sensor 50. This can be achieved by comparing the detected electrostatic voltage value with a preset voltage threshold. If the detected electrostatic voltage value is greater than the voltage threshold, the reaction cup 40 is considered to have electrostatic interference; otherwise, the reaction cup 40 is considered to have no electrostatic interference.

[0061] In this embodiment, since the robotic arm 10 and at least one of the multiple target functional areas 20 are equipped with an electrostatic sensor 50, the electrostatic conditions in different areas of the immunoassay analyzer 100 can be monitored, and the presence of electrostatic interference in the reaction cup 40 can be determined in a timely manner. This facilitates the timely resolution of electrostatic interference issues and avoids false negatives or false positives in the detection results of the immunoassay analyzer 100.

[0064] Specifically, the electrostatic detection module 200 is used to determine whether there is electrostatic interference in the reaction cup 40 based on the electrostatic voltage value detected by the electrostatic sensor 50. The determination can be made by comparing the detected electrostatic voltage value with a preset voltage threshold. If the detected electrostatic voltage value is greater than the voltage threshold, it is determined that there is electrostatic interference in the reaction cup 40; otherwise, it is determined that there is no electrostatic interference in the reaction cup 40.
