DETAILED DESCRIPTION

[0098] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0099] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0100] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or may be indirectly connected to the other element through an intermediate element.

[0101] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot 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" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. 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 the present invention.

[0102] Prior to this application, some people proposed the following automatic cleaning and maintenance scheme for the detection container:

[0103] (1) A high-concentration first cleaning liquid is used to automatically perform cleaning and maintenance of the detection container, and the high-concentration first cleaning liquid is directly discharged through the electrode assembly after cleaning, which will damage the electrode assembly. The electrode assembly needs to be replaced after cleaning and maintenance.

[0104] (2) Use a high-concentration first cleaning liquid to automatically perform cleaning and maintenance of the detection container, and add a bypass at the discharge port of the detection container for discharging the first cleaning liquid after cleaning. The high-concentration first cleaning liquid does not flow through the electrode assembly, so the electrode assembly does not need to be replaced after cleaning and maintenance. However, the disadvantages of this solution are: the introduction of the bypass is difficult to completely eliminate the impact on the measurement channel of the electrode assembly; when performing normal electrolyte measurements, if the bypass is filled with gas, the gas may be sucked into the measurement channel of the electrode assembly and affect the test; if the bypass is filled with liquid, the liquid will mix with the liquid in the measurement channel of the electrode assembly and affect the measurement.

[0105] (3) A high-concentration first cleaning liquid is used to automatically perform cleaning and maintenance of the detection container, and a waste liquid needle is set in the detection container, which can move up and down to absorb the first cleaning liquid after cleaning. The high-concentration first cleaning liquid can be directly sucked away by the waste liquid needle without flowing through the electrode assembly, so the electrode assembly does not need to be replaced after cleaning and maintenance. However, the disadvantage of this solution is that it can only be applied to the situation where there is no stirring actuator in the base detection container, and a vertical motion drive assembly needs to be configured for the waste liquid needle, which is relatively expensive.

The first liquid discharge component 310 is mainly used to provide a driving force for the liquid in the detection container 200 to flow out of the liquid discharge port and flow through the electrode assembly 100. The first waste liquid channel 320 is connected to the waste liquid collection container to discharge the liquid discharged by the first liquid discharge component 310 to the waste liquid collection container.

[0110] As an embodiment, the sample analyzer 10 further includes a first sample dispensing device 400, which is used to dispense the sample into the detection container 200.

The first cleaning liquid dispensing device 500 is mainly used to achieve quantitative distribution of the first cleaning liquid. The first cleaning liquid dispensing device 500 injects the first cleaning liquid into the detection container 200 by dispensing.

[0112] As an embodiment, the sample analyzer 10 further includes a first diluent dispensing device 600, which is used to dispense a first diluent into the detection container 200. The first diluent is mainly used to dilute the first cleaning solution in the detection container 200, so that the diluted first cleaning solution can be discharged from the electrode assembly 100 without damaging the electrode assembly 100. The first diluent dispensing device 600 injects the first diluent into the detection container 200 by dispensing.

[0113] 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 liquid discharge assembly 310 , the first sample dispensing device 400 , the first cleaning liquid dispensing device 500 , and the first diluent dispensing device 600 .

[0114] As an embodiment, the controller is electrically connected to the electrode assembly 100, the first liquid discharge assembly 310, the first sample dispensing device 400, the first cleaning liquid dispensing device 500, and the first diluent dispensing device 600. The controller is used to control the operation of the first liquid discharge assembly 310, the first sample dispensing device 400, the first cleaning liquid dispensing device 500, and the first diluent dispensing device 600, and is used to obtain the electrolyte determination result of the sample according to the electrical parameters of the electrode assembly 100 when the test liquid flows through the electrode assembly 100.

[0115] As an embodiment, the controller is configured with an electrolyte determination process. When executing the electrolyte determination process, the controller is configured to perform the following actions: control the first sample dispensing device 400 to distribute the sample to the detection container 200 to form a liquid to be tested, control the first liquid discharge component 310 to drive the liquid to be tested in the detection container 200 to flow through the liquid discharge port and the electrode assembly 100 in sequence and then be discharged to the first waste liquid channel 320, and obtain the electrical parameters of the electrode assembly 100 when the liquid to be tested flows through the electrode assembly 100, and obtain the electrolyte determination result of the sample according to the electrical parameters. The electrolyte determination process is used to enable the controller to automatically control the sample analyzer 10 to perform electrolyte determination of the sample. Specifically, in the electrolyte determination process, the first sample dispensing device 400 is first used to distribute the sample to the detection container 200 to form a liquid to be tested in the detection container 200, and then the first liquid discharge component 310 drives the liquid to be tested in the detection container 200 to flow from the liquid discharge port through the electrode assembly 100 and then be discharged to the first waste liquid channel 320, thereby realizing automatic electrolyte determination of the sample.

[0116] As an implementation mode, the controller is also configured with a cleaning and maintenance process. The cleaning and maintenance process is mainly used to perform regular cleaning and maintenance on the detection container 200. In this implementation mode, the cleaning and maintenance process is configured in the controller to automatically clean and maintain the detection container 200, so that regular cleaning and maintenance of the detection container 200 does not require manual participation, thereby simplifying the cleaning and maintenance operation process of the detection container 200.

[0117] As an embodiment, when executing the cleaning and maintenance process, the controller is configured to perform the following actions: control the first cleaning liquid dispensing device 500 to dispense the first cleaning liquid into the detection container 200 to clean the detection container 200, control the first dilution liquid dispensing device 600 to dispense the first dilution liquid into the detection container 200 to dilute the first cleaning liquid in the detection container 200, and control the first drainage component 310 to drive the diluted first cleaning liquid in the detection container 200 to pass through the drainage port and the electrode component 100 in sequence and then be discharged to the first waste liquid channel 320. In this embodiment, when the detection container 200 is regularly cleaned and maintained, the detection container 200 is first cleaned with a high-concentration first cleaning liquid to ensure that the contaminants on the wall of the detection container 200 can be cleaned. After the first cleaning liquid is cleaned, the first diluent is used to dilute the first cleaning liquid in the detection container 200, and then the diluted first cleaning liquid in the detection container 200 is controlled to be discharged through the drain port and the electrode assembly 100 in sequence. In this way, the dilution effect of the first diluent can be utilized so that the first cleaning liquid after cleaning will not damage the electrode assembly 100 when it flows through the electrode assembly 100 and is discharged, fully ensuring the reliability of the automatic cleaning and maintenance of the detection container 200. In this embodiment, the drain port and the first drain assembly 310 are used to discharge the cleaned and diluted first cleaning liquid, which can be conducive to making full use of the inherent structure in the sample analyzer 10 to realize the discharge of the first cleaning liquid, and the structure is simple.

[0118] As an embodiment, the first diluent is deionized water, which can dilute the high-concentration first cleaning solution, and is easy to obtain and low in cost. Of course, in specific applications, the first diluent is not limited thereto. For example, as an alternative embodiment, the first diluent can also be a salt solution.

[0119] As an embodiment, during the execution of the cleaning and maintenance process, the controller is also configured to: control the first diluent dispensing device 600 to distribute the amount of the first diluent into the detection container 200, so as to dilute the first cleaning liquid in the detection container 200 by more than 33 times. The first cleaning liquid can be diluted by more than 33 times to a safe concentration range, so that the diluted first cleaning liquid will not damage the electrode assembly 100 when flowing through the electrode assembly 100. In this embodiment, the first cleaning liquid in the detection container 200 is first diluted by more than 33 times with the first diluent, and then the first cleaning liquid and pollutants in the detection container 200 after cleaning are discharged through the electrode assembly 100 by the first drain assembly 310, which not only solves the problem of waste liquid discharge after cleaning, but also ensures that the discharge of the first cleaning liquid will not damage the electrode assembly 100.

[0120] As an embodiment, the sample is serum or plasma or urine or other body fluids. After the sample is collected from the patient, it is stored in a sample container, and the first sample distribution device 400 is used to absorb the sample from the sample container and distribute at least part of the absorbed sample into the detection container 200. The sample container is provided with an identification code, which includes at least one of a bar code, a QR code, and a radio frequency code.

[0121] As an embodiment, the sample analyzer 10 further includes a second diluent dispensing device 700, which is used to dispense a second diluent into the detection container 200, and the liquid to be tested is made of the sample dispensed by the first sample dispensing device 400 and the second diluent dispensed by the second diluent dispensing device 700. In this embodiment, the liquid to be tested is made of the sample and the second diluent. Of course, in a specific application, as an alternative embodiment, the liquid to be tested also only includes the sample, but not the second diluent.

[0122] As an embodiment, the first diluent and the second diluent are two different liquids. The first diluent is deionized water, and the second diluent is a saline solution used to dilute the sample. Of course, in a specific application, as an alternative embodiment, the first diluent and the second diluent can also be the same liquid, that is, the first cleaning liquid can also be diluted with a saline solution used to dilute the sample.

[0123] As an embodiment, the second diluent dispensing device 700 includes a second diluent needle, which is connected to the detection container 200 via a second connecting seat. The second diluent needle is immovable. In addition to being used to clean the inner wall of the detection container 200, the above-mentioned cleaning and maintenance process is also used to clean the outer wall of the second diluent needle.

[0124] As an embodiment, the sample analyzer 10 also includes an internal standard liquid dispensing device 800, which is used to distribute the internal standard liquid into the detection container 200, and the internal standard liquid dispensing device 800 includes an internal standard liquid needle, which is connected to the detection container 200 through a second connecting seat. The internal standard liquid needle is immovable. In addition to being used to clean the inner wall of the detection container 200, the above-mentioned cleaning and maintenance process is also used to clean the outer wall of the internal standard liquid needle.

[0125] As an embodiment, after the first cleaning liquid dispensing device 500 completes dispensing the first cleaning liquid into the detection container 200, the liquid level of the first cleaning liquid in the detection container 200 is greater than the liquid level of the liquid to be tested in the detection container 200 during the electrolyte detection process, that is, after the first cleaning liquid dispensing device 500 completes dispensing the first cleaning liquid into the detection container 200, the liquid level of the first cleaning liquid in the detection container 200 is greater than the liquid level of the liquid to be tested in the detection container 200 during the electrolyte detection process, that is, the liquid level of the first cleaning liquid in the cleaning and maintenance process is greater than the liquid level of the liquid to be tested in the electrolyte detection process. For example, after the first cleaning liquid dispensing device 500 completes dispensing the first cleaning liquid into the detection container 200, the liquid level of the first cleaning liquid in the detection container 200 is X1, and the liquid level of the liquid to be tested in the detection container 200 during the electrolyte detection process is X2, and X1>X2.

[0126] In this way, the cleaning height of the first cleaning liquid is greater than the highest contamination height of the liquid to be tested (excluding overflow, sample needle liquid throwing and other uncontrollable contamination height scenarios), so as to ensure that the first cleaning liquid can fully contact the contaminants in the detection container 200, so as to ensure the cleanliness and comprehensiveness of the cleaning of the detection container 200. As an embodiment, the liquid level height after dilution in the detection container 200 is greater than the liquid level height before dilution, that is: the liquid level height of the liquid in the detection container 200 after the first dilution liquid dispensing device 600 distributes the first dilution liquid into the detection container 200 is greater than the liquid level height of the liquid in the detection container 200 after the first cleaning liquid dispensing device 500 distributes the first cleaning liquid into the detection container 200. In this way, the first cleaning liquid in the detection container 200 and the cleaned contaminants can be rinsed clean by the first dilution liquid. It can be understood that the liquid level height after dilution in the detection container 200 is the liquid level height of the first cleaning liquid after dilution in the detection container 200.

[0127] As an embodiment, the controller is further configured to: after controlling the first cleaning liquid dispensing device 500 to dispense the first cleaning liquid into the detection container 200 for a first preset time, control the first diluent dispensing device 600 to dispense the first diluent into the detection container 200. In this embodiment, after the first cleaning liquid is dispensed, the detection container 200 is first soaked in the first cleaning liquid stock solution for a first preset time, and then the first diluent is used to dilute the first cleaning liquid in the detection container 200. In this way, the first cleaning liquid with a high concentration can be used to fully react with the pollutants on the inner wall of the detection container 200 before diluting the first cleaning liquid, which fully ensures the cleanliness and cleaning efficiency of the detection container 200.

[0128] As an embodiment, the sample analyzer 10 further includes a first stirring device, and the controller is further configured to: control the first stirring device to stir the first cleaning liquid in the detection container 200. In this embodiment, the first stirring device is used to stir the first cleaning liquid in the detection container 200. On the one hand, the power generated by the stirring of the first stirring device can be used to make the first cleaning liquid have a flushing effect on the contaminants on the inner wall of the detection container 200, which is conducive to better removing the contaminants on the inner wall of the detection container 200; on the other hand, the stirring effect of the first stirring device can be used to make the first cleaning liquid at different positions in the detection container 200 move to a position in contact with the inner wall of the detection container 200.

[0129] As an embodiment, the controller is further configured to: after controlling the first cleaning liquid dispensing device 500 to distribute the first cleaning liquid into the detection container 200, and before controlling the first diluent dispensing device 600 to distribute the first diluent into the detection container 200, control the first stirring device to stir the first cleaning liquid in the detection container 200 for a second preset time. That is, after controlling the first cleaning liquid dispensing device 500 to distribute the first cleaning liquid into the detection container 200, and before controlling the first diluent dispensing device 600 to distribute the first diluent into the detection container 200, control the first stirring device to stir the first cleaning liquid in the detection container 200 for a second preset time. That is, in the process of soaking the detection container 200 with the first cleaning liquid, the first stirring device is simultaneously controlled to stir the first cleaning liquid. In this embodiment, after dispensing the first cleaning liquid, the first stirring device is controlled to operate, and a simpler control method can be used to prevent the undesirable phenomenon of splashing of the first cleaning liquid due to the stirring action of the first stirring device during the process of dispensing the first cleaning liquid. Of course, in specific applications, as an alternative implementation scheme, it is not necessary to control the first stirring device to stir after the first cleaning liquid is distributed. The first stirring device can also be controlled to start stirring before the first cleaning liquid is distributed and after the first cleaning liquid has submerged the first stirring device.

[0130] As an embodiment, the controller is further configured to: in the process of controlling the first diluent dispensing device 600 to dispense the first diluent into the detection container 200, control the first stirring device to always remain in an activated state to stir the liquid in the detection container 200. In this embodiment, in the process of dispensing the first diluent, the first stirring device is controlled to always stir, which is conducive to accelerating the mixing of the first diluent and the first cleaning liquid.

[0131] As an embodiment, the first stirring device includes a stirring execution component and a stirring driving component, the stirring execution component is at least partially disposed in the detection container 200, and the stirring driving component is used to drive the stirring execution component to rotate and / or vibrate to stir the liquid in the detection container 200. In this embodiment, the stirring execution component stirs the liquid in the detection container 200 by contact. Of course, in specific applications, the setting method of the first stirring device is not limited to, for example, as an alternative embodiment, the first stirring device can also be an ultrasonic stirring device, and the ultrasonic stirring device can use contact stirring or non-contact stirring.

[0132] As an embodiment, the stirring actuator is located at the bottom of the inner cavity of the detection container 200, that is, the stirring actuator is located at the inner bottom of the detection container 200. This facilitates the installation of the stirring actuator and helps reduce the interference of the stirring actuator with the injection of liquid into the detection container 200.

[0133] As an embodiment, the controller is further configured to: after controlling the first diluent dispensing device 600 to dispense the first diluent into the detection container 200 for a third preset time, control the first drain assembly 310 to discharge the diluted first cleaning liquid in the detection container 200 to the first waste liquid channel 320 through the drain port and the electrode assembly 100 in sequence. In this embodiment, after the first diluent is dispensed, the diluted first cleaning liquid is first used to soak the detection container 200 for a third preset time, and then the diluted first cleaning liquid in the detection container 200 is discharged through the first drain assembly 310, so that the first cleaning liquid and the contaminants on the inner wall of the detection container 200 are washed off, and then the diluted first cleaning liquid is discharged.

[0134] As an embodiment, the electrode assembly 100 includes a measurement channel, a reference electrode 120 and at least one ion selective electrode 110, the ion selective electrode 110 is used to measure the target ion, 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 liquid discharge port is connected to the first liquid discharge assembly 310 through the measurement channel. Both the reference electrode 120 and the ion selective electrode 110 are at least partially disposed in the measurement channel, so that the liquid flowing through the measurement channel can contact the reference electrode 120 and the ion selective electrode 110.

[0135] As an embodiment, the sample analyzer 10 further includes a second liquid discharge assembly 900. The detection container 200 further includes an opening 210, which is connected to the inner cavity of the detection container 200 and is independent of the liquid discharge port. The second liquid discharge assembly 900 is used to discharge part of the liquid in the inner cavity through the opening 210. The controller is further configured to: in the process of controlling the first diluent dispensing device 600 to dispense the first diluent into the detection container 200 to dilute the first cleaning liquid, control the second liquid discharge assembly 900 to discharge part of the liquid in the detection container 200 through the opening 210. The second liquid discharge assembly 900 is mainly used to discharge part of the liquid in the detection container 200 in the process of the first diluent dispensing device 600 dispensing the first diluent into the detection container 200 to dilute the first cleaning liquid, so as to control the liquid level in the detection container 200 during the cleaning and maintenance process, so that the first diluent can dilute the first cleaning liquid in the detection container 200 to a safe dilution range that will not damage the electrode assembly 100 without increasing the volume of the detection container 200.

[0136] As an embodiment, the second liquid discharge assembly 900 discharges part of the liquid in the detection container 200 through the opening 210, including at least the first cleaning liquid being diluted.

[0137] As an embodiment, the opening 210 is located above the liquid discharge port, so that when the second liquid discharge component 900 discharges part of the liquid in the detection container 200, the liquid in the detection container 200 will not be drained, so that the dilution of the first cleaning liquid can proceed normally.

[0138] As an implementation manner, the second liquid-discharging component 900 has a liquid-sucking port 911 for sucking liquid from the detection container 200 . The liquid-sucking port 911 is disposed in the detection container 200 through the opening 210 or is in communication with the opening 210 .

[0139] As an implementation mode, the liquid suction port 911 is used to suck liquid from the detection container 200 above the stirring execution component, so that the second liquid discharge component 900 will not interfere with the stirring execution component.

[0140] As an embodiment, the controller is further configured to: in the process of controlling the first diluent dispensing device 600 to dispense the first diluent into the detection container 200, control the first stirring device to always remain in the start-up state to stir the liquid in the detection container 200 (e.g., the liquid in the detection container 200 is the first cleaning liquid being diluted), and control the second liquid discharge component 900 to discharge part of the liquid in the detection container 200 through the opening 210 to control the liquid level of the liquid in the detection container 200 (e.g., the first cleaning liquid being diluted) during the dilution process. In this embodiment, during the dispensing of the first diluent, the second liquid discharge component 900 continuously absorbs liquid to control the liquid level, and the first stirring device continuously stirs to mix the first cleaning liquid and the first diluent, thereby facilitating the reduction of the phenomenon that the dispensed first diluent is discharged by the second liquid discharge component 900 without being mixed with the first cleaning liquid.

[0141] As an implementation mode, during the cleaning and maintenance process, the height of the position where the liquid suction port 911 is located when sucking liquid is greater than the liquid level of the liquid to be tested in the detection container 200 during the electrolyte detection process. The liquid suction position of the liquid suction port 911 can be used to control the liquid level of the first cleaning liquid in the detection container 200. In this implementation mode, the liquid suction position height of the second liquid discharge component 900 is set to be greater than the liquid level of the liquid to be tested during the electrolyte determination process. In this way, the cleaning liquid level controlled by the second liquid discharge component 900 during the cleaning and maintenance process is greater than the highest contamination height during the electrolyte determination process, thereby ensuring the cleanliness and comprehensiveness of the cleaning of the detection container 200.

[0142] As an embodiment, the controller is further configured to: before controlling the first diluent dispensing device 600 to dispense the first diluent into the detection container 200 to dilute the first cleaning solution, control the second liquid discharge component 900 to start. In this embodiment, the second liquid discharge component 900 is controlled to start first, and then the first diluent dispensing device 600 is controlled to dispense the first diluent into the detection container 200, so that the second liquid discharge component 900 can better control the liquid level of the liquid in the detection container 200, thereby preventing the liquid in the detection container 200 from overflowing during the dilution process.

[0143] As an embodiment, the controller is further configured to: in the process of controlling the first diluent dispensing device 600 to dispense the first diluent into the detection container 200 to dilute the first cleaning liquid, control the second liquid discharge component 900 to always keep the startup state, so that the second liquid discharge component 900 continues to discharge liquid, thereby being able to well control the liquid level height of the liquid in the detection container 200 during the dilution process. Of course, in a specific application, as an alternative embodiment, in the process of controlling the first diluent dispensing device 600 to dispense the first diluent into the detection container 200 to dilute the first cleaning liquid, the second liquid discharge component 900 can also be controlled to operate in an intermittent liquid discharge mode.

[0144] As an embodiment, when performing the cleaning and maintenance process, the controller is further configured to: control the second drain assembly 900 to maintain a startup state within a first preset time period when the detection container 200 is soaked with the first cleaning liquid. Since the first cleaning liquid reacts with the pollutants on the inner wall of the detection container 200 during the soaking of the detection container 200 with the first cleaning liquid, a large amount of foam will be generated. Therefore, in order to prevent the foam generated during the soaking process from overflowing the top opening of the detection container 200, the second drain assembly 900 is controlled to maintain a startup state within the first preset time period of soaking so that the second drain assembly 900 discharges the foam generated during the cleaning of the detection container 200 with the first cleaning liquid. In the process of performing the cleaning and maintenance process, the height of the position where the liquid suction port 911 is located when sucking liquid is greater than the liquid level height of the liquid to be tested in the detection container 200 during the electrolyte detection process. For example, the height of the position where the liquid suction port 911 is located when sucking liquid during the cleaning and maintenance process is D1, and the liquid level height of the liquid to be tested in the detection container 200 during the electrolyte detection process is D2, and D1>D2.

[0145] As an embodiment, the controller is further configured to: in the process of controlling the first cleaning liquid dispensing device 500 to dispense the first cleaning liquid into the detection container 200, control the second liquid discharge component 900 to discharge part of the liquid in the detection container 200 through the opening 210 to control the liquid level of the first cleaning liquid in the detection container 200. In this embodiment, in the process of dispensing the first cleaning liquid, the liquid level of the detection container 200 is controlled by opening the second liquid discharge component 900, thereby facilitating reducing the quantitative accuracy requirement of the first cleaning liquid dispensing device 500 for dispensing the first cleaning liquid.

[0146] As an embodiment, when executing the cleaning and maintenance process, the controller is further configured to: before controlling the first cleaning liquid dispensing device 500 to dispense the first cleaning liquid into the detection container 200, control the second liquid discharge component 900 to start. In this embodiment, before dispensing the first cleaning liquid into the detection container 200, the second liquid discharge component 900 is first turned on, and there is no need to worry about when to turn on the second liquid discharge component 900 during the first cleaning liquid dispensing process, which is conducive to simplifying the control program. Of course, in a specific application, as an alternative embodiment, the second liquid discharge component 900 can also be controlled to start after the first cleaning liquid dispensing device 500 is controlled to dispense part of the first cleaning liquid into the detection container 200.

[0147] As an embodiment, the opening 210 is the top opening of the detection container 200, the second liquid discharge component 900 includes a liquid suction needle 910, a second liquid discharge pipeline 920 and a second liquid discharge power component 930, at least part of the liquid suction needle 910 is inserted into the inner cavity from the opening 210, the liquid suction port 911 of the second liquid discharge component 900 is formed on the liquid suction needle 910, and the second liquid discharge power component 930 is connected to the liquid suction needle 910 through the second liquid discharge pipeline 920. Controlling the second liquid discharge component 900 to discharge part of the liquid in the detection container 200 through the opening 210 includes: controlling the second liquid discharge power component 930 to start, so that the second liquid discharge power component 930 drives the liquid suction needle 910 to suck liquid from the detection container 200 (e.g., sucking part of the first cleaning liquid in dilution). This embodiment is simple in structure and easy to control by designing the second liquid discharge component 900 as a driving scheme for the liquid suction needle 910.

[0148] It can be understood that the partial liquid includes at least a portion of the diluted first cleaning liquid, that is, the partial liquid discharged from the detection container 200 by the second liquid discharge component 900 through the opening 210 includes at least a portion of the diluted first cleaning liquid. In addition, the liquid sucked from the detection container 200 by the second liquid discharge power component 930 driving the liquid aspiration needle 910 includes at least a portion of the diluted first cleaning liquid.

[0149] As an implementation manner, the liquid aspiration port 911 of the second liquid discharge assembly 900 is located at the needle tip of the liquid aspiration needle 910 .

[0150] As an embodiment, the first liquid discharge assembly 310 includes a first liquid discharge pipeline 311 and a first liquid discharge power component 312, and the first liquid discharge power component 312 is connected to the electrode assembly 100 through the first liquid discharge pipeline 311. The first liquid discharge power component 312 and the second liquid discharge power component 930 are two independent components, that is, the first liquid discharge power component 312 and the second liquid discharge power component 930 are two different components.

[0151] As an implementation manner, the first liquid discharge power component 312 is a second syringe. The second syringe is an electrically controlled syringe.

[0152] As an implementation manner, the second liquid discharge power component 930 is a pump, and the pump can work by continuous suction, so that the liquid level in the detection container 200 can be better controlled by the continuous suction of the second liquid discharge power component 930.

[0153] It can be understood that in the embodiments of the present application, suction can also be referred to as absorption, which is used to describe the action or operation of providing power through a power component (such as a pump, a syringe) to generate suction to attract a certain medium.

[0154] As an embodiment, the liquid-pipetting needle 910 is arranged stationary relative to the detection container 200, that is, after the liquid-pipetting needle 910 is installed on the sample analyzer 10, it cannot move relative to the detection container 200. Since the inner bottom of the detection container 200 is provided with a stirring actuator, even if the liquid-pipetting needle 910 can move, it is difficult to move to the inner bottom of the detection container 200 to suck out the liquid in the detection container 200. Therefore, in this embodiment, the setting of the liquid-pipetting needle 910 is mainly used to control the liquid level in the detection container 200, and the final drainage still has to use the first drainage component 310. In this embodiment, by setting the liquid-pipetting needle 910 in a fixed and immovable manner, on the premise of achieving the effect of controlling the liquid level in the detection container 200 in the cleaning and maintenance process through the liquid-pipetting needle 910, it is helpful to simplify the control program of the controller. Of course, in specific applications, the arrangement of the pipette needle 910 is not limited to this. For example, as an alternative embodiment, the second drainage component 900 also includes a moving mechanism, which is used to drive the pipette needle 910 to move horizontally and / or vertically; in this alternative embodiment, the second drainage component 900 is controlled to discharge part of the liquid in the detection container 200 through the opening 210, including: first controlling the moving mechanism to drive the pipette port 911 of the pipette needle 910 to move to the target pipetting position, and then controlling the second drainage power component 930 to start, so that the second drainage power component 930 drives the pipette needle 910 to pipette liquid from the detection container 200.

[0155] As an embodiment, the liquid pipetting needle 910 is detachably connected to the detection container 200 through the first connection seat. The first connection seat can be directly connected to the detection container 200, or it can be indirectly connected to the detection container 200. Of course, in a specific application, the fixing method of the liquid pipetting needle 910 is not limited to this. For example, as an alternative embodiment, the liquid pipetting needle 910 can also be pre-buried in the detection container 200, that is, the liquid pipetting needle 910 is fixed to the detection container 200 by insert molding.

[0156] As an embodiment, the detection container 200 includes a container body and a frame, the frame is arranged outside the container body, the frame and the container body are integrally formed or the frame and the container body are detachably connected. The liquid suction needle 910 is detachably connected to the frame through a first connecting seat.

[0157] As an embodiment, the first connection seat is a plastic block, which has low material cost and is easy to manufacture. Of course, in specific applications, the first connection seat is not limited to being made of plastic, but can also be made of metal or made of plastic and metal.

[0158] As an implementation mode, the first connection base is connected to the frame of the detection container 200 by screws. Of course, in specific applications, the installation method of the first connection base is not limited to this. For example, the first connection base can also be installed and fixed by a snap connection method.

[0159] As an embodiment, the second connecting seat for fixing the second diluent needle and the internal standard liquid needle is a plastic block, the first connecting seat is stacked on top of the second connecting seat, and the first connecting seat and the second connecting seat share the same screw to be connected to the frame of the detection container 200.

[0160] In the above solution, the opening 210 is the top opening of the detection container 200 , and the second liquid discharge component 900 aspirates liquid from the detection container 200 via a liquid aspiration needle 910 that penetrates through the opening 210 and is disposed in the detection container 200 . Of course, in specific applications, the arrangement of the opening 210 and the second drainage assembly 900 is not limited thereto. For example, as an alternative embodiment, the opening 210 is arranged on the side wall of the detection container 200, and the second drainage assembly 900 includes a second drainage power component 930 and a second drainage pipeline 920. The second drainage power component 930 is connected to the opening 210 through the second drainage pipeline 920, and the pipe opening of the second drainage pipeline 920 connected to the opening 210 forms the liquid suction port 911 of the second drainage assembly 900; controlling the second drainage assembly 900 to discharge part of the liquid in the detection container 200 through the opening 210 includes: controlling the second drainage power component 930 to start, so that the second drainage power component 930 drives the second drainage pipeline 920 to suck liquid from the detection container 200. In this alternative embodiment, the second drainage assembly 900 sucks liquid from the detection container 200 by means of the opening 210 on the side wall of the detection container 200.

[0161] As an embodiment, the part of the liquid at least includes the first cleaning liquid in a part of dilution, that is, the part of the liquid discharged from the detection container 200 by the second liquid discharge component 900 through the opening 210 at least includes the first cleaning liquid in a part of dilution. Moreover, the second liquid discharge power component 930 drives the second liquid discharge pipeline 920 to absorb liquid from the detection container 200, and the liquid absorbed by the second liquid discharge power component 930 at least includes the first cleaning liquid in a part of dilution.

[0162] As an embodiment, controlling the first diluent dispensing device 600 to dispense the first diluent into the detection container 200 to dilute the first cleaning liquid in the detection container 200 includes: controlling the first diluent dispensing device 600 to perform a first dispensing operation to dispense a first preset amount of the first diluent into the detection container 200, and controlling the second liquid discharge component 900 to always remain in a started state during the first diluent dispensing device 600 performing the first dispensing operation; controlling the second liquid discharge component 900 to stop running after the first dispensing operation is completed; and controlling the first diluent dispensing device 600 to perform a second dispensing operation to dispense a second preset amount of the first diluent into the detection container 200. In this embodiment, the height of the liquid level in the detection container 200 during the cleaning and maintenance process is mainly controlled by the second liquid discharge component 900. Specifically, this embodiment divides the dispensing of the first diluent into two steps: a first dispensing operation and a second dispensing operation. During the first dispensing operation, the second liquid discharge component 900 aspirates liquid, so that after the first dispensing operation is completed, the liquid level in the detection container 200 is flush with the position of the liquid aspiration port 911 of the second liquid discharge component 900. During the second dispensing operation, since the second liquid discharge component 900 does not aspirate liquid, after the second dispensing operation is completed, the liquid level in the detection container 200 is higher than the position of the liquid aspiration port 911 of the second liquid discharge component 900, so that the liquid level after dilution in the detection container 200 is greater than the liquid level before dilution. By dividing the dispensing process of the first diluent into two steps of dispensing operations, the liquid level after dilution is controlled by controlling the start and stop of the second liquid discharge component 900 in the two-step dispensing operation, and the implementation method is simple and easy to implement.

[0163] As an embodiment, the sample analyzer 10 further includes a first cleaning pool. The first diluent dispensing device 600 includes a first pipette needle 610, a first infusion pipeline, a first syringe, a first diluent supply assembly and a first drive assembly. The first pipette needle 610 is used to dispense the first diluent into the detection container 200. The first diluent supply assembly is connected to the first pipette needle 610 through the first infusion pipeline to transport the first diluent to the first infusion pipeline and the first pipette needle 610. The first syringe is connected to the first infusion pipeline to drive the first pipette needle 610 to perform suction and discharge actions. The first drive assembly is at least used to drive the first pipette needle 610 to move to the first dispensing position of the detection container 200 and the first cleaning position of the first cleaning pool respectively. The first cleaning pool is used to clean the first pipette needle 610. The cleaning method of the first pipette needle 610 is to rinse the inner wall of the first pipette needle 610 by transporting the first diluent to the first infusion pipeline and the first pipette needle 610 through the first diluent supply assembly.

[0164] As an embodiment, the first diluent supply assembly includes a first diluent container and a liquid pump, and the liquid pump is used to draw the first diluent from the first diluent container and supply it to the first infusion pipeline and the first pipette needle 610. Of course, in specific applications, the configuration of the first diluent supply assembly is not limited thereto.

[0165] As an embodiment, the first preset amount is greater than the second preset amount. The first dispensing operation is mainly used to dilute the first cleaning solution in the detection container 200 to a safe range, and the second dispensing operation is mainly used to make the liquid level in the detection container 200 after dilution greater than the liquid level before dilution, so the amount of the first diluent to be dispensed in the first dispensing operation is greater than the amount of the first diluent to be dispensed in the second dispensing operation.

[0166] As an embodiment, controlling the first diluent dispensing device 600 to perform a first dispensing operation to dispense a first preset amount of the first diluent into the detection container 200 includes: controlling the first driving component to drive the first pipetting needle 610 to move to the first dispensing position, and controlling the first diluent supply component to deliver the first diluent to the first pipetting needle 610 located at the first dispensing position through the first infusion pipeline, so that the first pipetting needle 610 dispenses the first preset amount of the first diluent into the detection container 200. Since the first dispensing operation requires dispensing a relatively large amount of the first diluent, and the second liquid discharge component 900 is used to control the liquid level in the detection container 200 in the first dispensing operation, the first diluent supply component is used to deliver the first diluent to the first pipetting needle 610 in the first dispensing operation, which is conducive to the rapid performance of the first dispensing operation.

[0167] As an embodiment, in the second dispensing operation, the first syringe is used to deliver the first diluent to the first pipetting needle 610. Since the second dispensing operation requires a relatively small amount of the first diluent to be dispensed, and there is no second liquid discharge assembly 900 to control the liquid level in the detection container 200 in the second dispensing operation, the first diluent dispensing in the second dispensing operation requires the use of a power assembly with a quantitative function to deliver the first diluent to the first pipetting needle 610.

[0168] As an embodiment, the first diluent dispensing device 600 is controlled to perform a second dispensing operation to dispense a second preset amount of the first diluent into the detection container 200, including: controlling the first driving component to drive the first pipetting needle 610 to move to the first cleaning position, controlling the first diluent supply component to deliver the first diluent to the first pipetting needle 610 located at the first cleaning position through the first infusion pipeline to rinse the inner wall of the first pipetting needle 610, controlling the first syringe to draw a third preset amount of the first diluent from the first infusion pipeline during the process of the first diluent rinsing the inner wall of the first pipetting needle 610, controlling the first driving component to drive the first pipetting needle 610 to move to the first dispensing position, and controlling the first syringe to push the second preset amount of the first diluent to the first pipetting needle 610 and discharge it into the detection container 200; wherein the third preset amount is greater than or equal to the second preset amount. In this embodiment, after the first dispensing operation is completed, the first pipette needle 610 is first controlled to move to the first cleaning tank for cleaning, and after the cleaning is completed, part of the first diluent is stored in the first syringe, and the first diluent stored in the first syringe is used as the source of the first diluent for the second dispensing operation. This control method is simple and easy to accurately control the dispensing amount of the first diluent for the second dispensing operation.

[0169] As an embodiment, the controller is further configured to: after controlling the first syringe to draw the third preset amount of the first diluent from the first infusion line, and before controlling the first drive assembly to drive the first pipetting needle 610 to move to the first dispensing position, control the first syringe to push the fourth preset amount of the first diluent to the first pipetting needle 610 and discharge it to the first cleaning tank; wherein the difference between the third preset amount and the fourth preset amount is greater than or equal to the second preset amount. The cleaning of the first pipetting needle 610 in the first cleaning tank includes a first cleaning process and a second cleaning process. The first cleaning process is a normal cleaning process, and the first cleaning process includes: first controlling the first diluent supply assembly to open to rinse the inner wall of the first pipetting needle 610 with the first diluent, then drawing the fourth preset amount of the first diluent from the first infusion line by the first syringe, and then controlling the first syringe to push all the fourth preset amount of the first diluent drawn to the first pipetting needle 610 and discharge it to the first cleaning tank. The second cleaning process is a special cleaning process, and the second cleaning process includes: first controlling the first diluent supply component to open to rinse the inner wall of the first pipette needle 610 with the first diluent, then sucking the third preset amount of the first diluent from the first infusion pipeline through the first syringe, and then controlling the first syringe to push the sucked part of the first diluent (the fourth preset amount of the first diluent) to the first pipette needle 610 to discharge it into the first cleaning pool, and allowing the first syringe to store the second preset amount of the first diluent for use as the first diluent source for the second dispensing operation. In this embodiment, by optimizing the design of the cleaning process of the first pipette needle 610, the first pipette needle 610 stores the first diluent for quantitative distribution of the first diluent in the second distribution operation after cleaning, and its implementation method is simple.

[0170] As an embodiment, the controller is further configured to: after controlling the first diluent dispensing device 600 to perform the second dispensing operation, and before controlling the first draining assembly 310 to discharge the diluted first cleaning liquid in the detection container 200 to the first waste liquid channel 320, control the second draining assembly 900 to discharge part of the diluted first cleaning liquid in the detection container 200 through the opening 210. In this embodiment, after the detection container 200 is cleaned, before the first draining assembly 310 drains the liquid, the second draining assembly 900 is first drained to make the liquid level in the detection container 200 drop to the same level as the liquid suction port 911 of the second draining assembly 900, and then the first draining assembly 310 is used to drain the liquid. In this way, it is helpful to avoid the phenomenon of liquid hanging on the liquid suction needle 910 after the liquid discharge is completed.

[0171] As an embodiment, the first cleaning liquid dispensing device 500 includes a first cleaning liquid dispensing needle 510 and a first cleaning liquid dispensing power component; controlling the first cleaning liquid dispensing device 500 to dispense the first cleaning liquid into the detection container 200 includes: controlling the first cleaning liquid dispensing power component to drive the first cleaning liquid dispensing needle 510 to perform the following dispensing operation for a third preset number of times or a third preset time: dispensing the first cleaning liquid into the detection container 200. In this embodiment, the first cleaning liquid distribution is achieved by multiple dispensings.

[0172] As an embodiment, at least two of the first cleaning liquid dispensing device 500, the first diluent dispensing device 600, and the first sample dispensing device 400 are the same device, that is, the first cleaning liquid dispensing device 500 and the first sample dispensing device 400 are the same device; and / or, the first cleaning liquid dispensing device 500 and the first diluent dispensing device 600 are the same device; and / or, the first diluent dispensing device 600 and the first sample dispensing device 400 are the same device. At least two of the first cleaning liquid dispensing device 500, the first diluent dispensing device 600, and the first sample dispensing device 400 are the same device, which can realize the reuse of the dispensing device, thereby simplifying the structure of the sample analyzer 10.

[0173] As an implementation scheme, the first cleaning liquid dispensing device 500, the first diluent dispensing device 600 and the first sample dispensing device 400 are the same device, that is, in addition to being used to distribute samples to the Axin detection container 200, the first sample dispensing device 400 is also reused for dispensing the first cleaning liquid and the first diluent, which helps to simplify the structure of the pseudo-analyzer and reduce the cost of the sample analyzer 10.

[0174] As an embodiment, the sample analyzer 10 pre-stores at least one of the following preset conditions: reaching the fourth preset time after the sample analyzer 10 is turned on (also referred to as the corresponding power-on time after the sample analyzer is turned on reaches the fourth preset time); reaching the fifth preset time before the sample analyzer 10 is turned off (setting a preset shutdown time point, the time from the current time point to the preset shutdown time point of the sample analyzer is the fifth preset time); reaching the sixth preset time since the last cleaning and maintenance process was executed; the time for the sample analyzer 10 to continuously execute the electrolyte determination process reaches the seventh preset time; the time for the sample analyzer 10 to cumulatively execute the electrolyte determination process since the last cleaning and maintenance process was executed reaches the eighth preset time; the number of times the sample analyzer 10 continuously executes the electrolyte determination process reaches the first preset number; the number of times the sample analyzer 10 cumulatively executes the electrolyte determination process since the last cleaning and maintenance process is executed reaches the second preset number; reaching the preset time point of the preset cycle. The controller is also configured to: execute the cleaning and maintenance process when any of the preset conditions is met. In this embodiment, the cleaning and maintenance process of the detection container 200 does not occupy the time of the electrolyte determination process, and when the preset conditions are met, it is automatically executed according to the set program, which is conducive to making the operator basically unaware of the cleaning and maintenance process of the detection container 200.

[0175] As an embodiment, the controller is further configured to: obtain information that the detection container 200 needs to be cleaned and maintained according to the instructions input by the operator through the human-computer interaction device. That is, the operator can clean and maintain the detection container 200 according to his own needs.

Among them, the second sample dispensing device and the first sample dispensing device 400 are the same device or two independent devices. In this embodiment, in addition to the integrated electrolyte measurement function, the sample analyzer 10 also integrates at least one of the biochemical measurement function, the immunoassay function, and the coagulation measurement function, that is, the electrolyte measurement module can be integrated in a biochemical analyzer or an immunoassay analyzer or a coagulation analyzer, so that the functions of the sample analyzer 10 are diversified. 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 stand-alone electrolyte measurement device.

[0178] As an embodiment, the first sample dispensing device 400 includes a first sample needle 410, and the first sample needle 410 is used to distribute at least part of the sample in the sample container to the detection container 200; the second sample dispensing device includes a second sample needle, and the second sample needle is used to distribute at least part of the sample in the sample container to the reaction container; the reagent dispensing device includes a reagent needle, and the reagent needle is used to distribute at least part of the reagent in the reagent container to the reaction container; the sample analyzer 10 also includes a cleaning device and a second stirring device, and the second stirring device includes a stirring rod, and the stirring rod is used to stir the sample, reagent and / or reaction liquid in the reaction container.

[0179] As an implementation manner, the second liquid discharge power component 930 and the liquid discharge pump are two different components, that is, the second liquid discharge power component 930 and the liquid discharge pump are two independent components.

[0180] The present embodiment also provides a cleaning and maintenance method for the detection container 200 in the sample analyzer 10, and the cleaning and maintenance method includes the following steps: controlling the first cleaning liquid dispensing device 500 to dispense the first cleaning liquid into the detection container 200 to clean the detection container 200; controlling the first diluent dispensing device 600 to dispense the first diluent into the detection container 200 to dilute the first cleaning liquid in the detection container 200; controlling the first liquid discharge component 310 to discharge the diluted first cleaning liquid in the detection container 200 through the liquid discharge port of the detection container 200 and the electrode component 100 to the first waste liquid channel 320 in sequence.

[0181] The specific principles and implementation methods of the cleaning and maintenance method provided in this embodiment are similar to the control principles and implementation methods described in the above-mentioned sample analyzer 10, and will not be described in detail here.

[0182] This embodiment also provides a computer-readable storage medium, which stores a computer program. When the computer program is executed by a processor (such as the above-mentioned controller), the processor implements the steps of the cleaning and maintenance method of the detection container 200 in the above-mentioned sample analyzer 10. The computer-readable storage medium may be an internal storage unit of the above-mentioned sample analyzer 10, such as a hard disk or memory of the sample analyzer 10; or, the computer-readable storage medium may also be an external storage device of the sample analyzer 10, such as a plug-in hard disk, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), etc. equipped on the sample analyzer 10.

[0183] The automatic cleaning and maintenance scheme in the detection container 200 in this embodiment is: use the first cleaning liquid to soak and dissolve the pollutants in the detection container 200, the open top of the detection container 200, and the surfaces of the steel needles connected to the detection container 200. Since the high-concentration first cleaning liquid will damage the electrode assembly 100 once it flows through the electrode assembly 100, a liquid aspiration needle 910 and a second liquid discharge power component 930 are added, and the first sample needle 410 is used to inject deionized water to dilute it to reduce the concentration of the first cleaning liquid in the detection container 200 to a concentration that allows it to flow through the electrode assembly 100.

[0184] As an implementation method, the cleaning and maintenance process of the detection container 200 in the sample analyzer 10 includes the following steps:

[0185] 1) Initial state preparation step, emptying the detection container 200, this step may not be set;

[0186] 2) The first cleaning liquid cleaning step includes: 2.1) turning on the second liquid discharge power component 930, and the liquid aspiration needle 910 starts to aspirate to control the liquid level of the first cleaning liquid; 2.2) the first sample needle 410 (i.e., the first pipetting needle 610) moves to the first cleaning liquid aspiration position to aspirate the preset first cleaning liquid; 2.3) the first sample needle 410 moves to the sample addition position of the detection container 200 to discharge the first cleaning liquid; 2.4) repeating steps 2.2) and 2.3) for a preset number of times; 2.5) turning on the first stirring device and soaking for a first preset time. Since the first cleaning liquid decomposes pollutants and produces a large amount of foam during soaking, the second liquid discharge power component 930 needs to remain in the turned-on state.

[0187] 3) Dilution step, the second liquid discharge power component 930 remains in the open state, and the liquid aspiration needle 910 remains in the suction state; the first sample needle 410 moves to the sample loading position of the detection container 200, opens the inner wall cleaning pump valve (i.e., the liquid pump of the first diluent supply component) and injects deionized water (i.e., the first diluent) to dilute the first cleaning liquid in the detection container 200; and closes the second liquid discharge power component 930.

[0188] 4) After dilution, the first sample needle 410 performs a special cleaning sequence in the first cleaning tank, and the first syringe reserves a second preset amount of deionized water; the second sample needle moves to the sample adding position of the detection container 200, and injects a second preset amount of deionized water into the detection container 200 to make the liquid level of the water washing greater than the liquid level of the first cleaning liquid; soak for a second preset time.

[0189] 5) Liquid discharge step, opening the second liquid discharge power component 930 to discharge part of the diluted first cleaning liquid; the first liquid discharge power component 312 of the cranium skull empty the diluted first cleaning liquid in the detection container 200; closing the second liquid discharge power component 930.

[0190] 6) Restore the test status step and execute multiple injection processes.
