AI Technical Summary
In the intermittent injection scenario, the liquid chromatography analyzer has low utilization efficiency, slow detection speed, and is difficult to use online with other analyzers, resulting in blockage of the sample transmission track.
By using a combination of energy storage devices and locking and placement devices, by setting energy storage devices and locking and placement devices in the liquid phase fluid supply component, the locking and placement device is controlled to release the potential energy of the energy storage device in the released state to store and release the pressure of the liquid phase fluid. In the locked state, the potential energy storage and release assembly is prevented from releasing the stored potential energy, thereby achieving efficient utilization and rapid pressure building of liquid phase fluid.
It reduces the energy loss of intermittent injection, improves detection speed, avoids transmission track blockage caused by long-term queuing of samples, and ensures sample detection efficiency in online state.

Abstract
Description
Sample analysis system, liquid chromatography equipment and control method thereof Technical Field
[0001] The present application relates to the field of in vitro diagnostic equipment, and in particular to a sample analysis system, a liquid chromatography device, and a control method for a liquid chromatography device. Background Art
[0002] The normal working process of a liquid chromatography analyzer provided by the related technology is: first, the pressure of the liquid phase fluid is driven by the driving device to reach the target pressure value or target pressure range to achieve pressure building, and then the chromatography analysis project is started. After the chromatography analysis project is completed, if there is no sample to perform the chromatography analysis project, the driving device is stopped to achieve pressure relief.
[0003] When the above-mentioned liquid chromatograph is applied to a scenario requiring frequent intermittent injection, the liquid circuit system needs to frequently repeat the process of pressure building, executing chromatographic analysis items, and pressure relief, which leads to the following problems in the specific application of the liquid chromatograph: (1) Frequent pressure building and pressure relief will lead to loss of liquid phase fluid, thereby resulting in relatively low utilization efficiency of liquid phase fluid; (2) The pressure building process takes a long time, and repeated pressure building leads to a relatively slow detection speed of the liquid chromatograph in the scenario of intermittent injection, making it difficult for the liquid chromatograph to be used online with analyzers of other analysis items, because when the liquid chromatograph is connected to other analyzers, the pressure building process will cause the sample to be stuck on the track, thereby blocking the sample transmission channel of other analyzers, thereby reducing the detection efficiency of the sample. Based on this, the liquid chromatograph is generally operated in a stand-alone mode, and it is recommended that the operator concentrate on injecting samples on the liquid chromatograph stand-alone to reduce the process of pressure building and pressure relief. In this way, it will take a long time for the chromatographic analysis items of some samples to issue test reports, which is likely to cause patient dissatisfaction. Summary of the Invention
[0004] The first purpose of the present application is to provide a sample analysis system, which aims to solve the technical problems of low liquid phase fluid utilization efficiency and slow detection speed when the liquid chromatograph is used in the intermittent sampling scenario in the related art.

[0082] The locking and releasing device can switch between a locked state and a released state: in the locked state, the locking and releasing device applies a force to the potential energy storage and release component to lock the potential energy storage and release component, thereby preventing it from moving relative to the shell, so as to prevent the potential energy storage and release component from releasing the stored potential energy; in the released state, the potential energy storage and release component can store potential energy by moving relative to the shell through the pressure of the fluid, and, when the locking and releasing device removes the force applied to the potential energy storage and release component, the potential energy storage and release component is released, thereby allowing the potential energy storage and release component to move relative to the shell, so as to allow the potential energy storage and release component to release the stored potential energy.

[0091] After the locking and releasing device is switched to the locking state, if information is obtained that a blood sample needs to perform a chromatographic analysis project, the locking and releasing device is controlled to switch from the locking state to the releasing state, so that the potential energy storage and release component releases the stored potential energy to assist in driving the liquid phase fluid to flow toward the chromatographic column.
[0092] As an embodiment, the control method further includes: before executing a first chromatographic analysis project after the liquid chromatograph is powered on, controlling the first driving device to start and keep running for a third preset time period so that the pressure of the liquid phase fluid flowing to the chromatographic column reaches a target pressure value or a target pressure range; during the execution of the chromatographic analysis project, controlling the first driving device to drive the liquid phase fluid to flow at the target pressure value or a pressure value within the target pressure range to elute the test solution adsorbed on the chromatographic column;
[0093] If information is obtained that a chromatographic analysis project needs to be performed on a blood sample, controlling the lock-and-release device to switch from the locked state to the released state includes: first controlling the first driving device to start and keep running for a second preset time period so that the pressure of the liquid phase fluid flowing to the chromatographic column is greater than zero and less than the target pressure value or less than the lower limit of the target pressure range, and then controlling the lock-and-release device to switch from the locked state to the released state;
[0094] The control method further includes: after controlling the lock-release device to switch from the locked state to the released state, first controlling the first driving device to continue to operate for a fourth preset time period so that the pressure of the liquid-phase fluid flowing to the chromatographic column approximately reaches the target pressure value or the target pressure range, and then controlling the reversing valve to switch to a state connecting the liquid-phase fluid supply assembly, the test liquid preparation channel, and the chromatographic column, so that the liquid-phase fluid supply assembly drives the test liquid in the test liquid preparation channel to be delivered to the chromatographic column through the liquid-phase fluid;

[0099] The sample analysis system, liquid chromatography equipment and control method of the liquid chromatography equipment provided by the present application are provided with an energy storage device and a lock-and-release device in a liquid-phase fluid supply component, the lock-and-release device is provided to release the potential energy storage and release component of the energy storage device in a released state to allow the energy storage device to store potential energy and release potential energy under the pressure of the liquid-phase fluid, and the lock-and-release device is provided to lock the potential energy storage and release component in a locked state to prevent the energy storage device from releasing the stored potential energy, so that the liquid-phase fluid supply component has the function of storing and releasing potential energy in addition to the function of providing liquid-phase fluid of a certain pressure. The potential energy stored in the energy storage device can be used to reduce the energy loss in the intermittent sampling scenario, and the potential energy released by the energy storage device can be used to assist in the rapid pressure building of the liquid-phase fluid, thereby accelerating the speed of re-building pressure in the intermittent sampling scenario. Specifically, within the first preset time period after completing a chromatographic analysis project for a blood sample, if no information is obtained that there are other blood samples that need to perform chromatographic analysis projects, the present application controls the locking and releasing device to lock the potential energy storage and release component to prevent the potential energy storage and release component from releasing the stored potential energy, and controls the first driving component of the liquid-phase fluid supply component to stop running; when information is obtained again that there is a blood sample that needs to perform a chromatographic analysis project, the locking and releasing device is controlled to release the potential energy storage and release component so that the potential energy storage and release component assists in driving the liquid-phase fluid to flow toward the reversing valve and the chromatographic column by releasing the stored potential energy, thereby reducing energy loss through the potential energy stored in the energy storage device, and accelerating the speed of re-pressure building through the potential energy released by the energy storage device. Applying the solution of the present application to the scenario of intermittent sampling can avoid the problem that the samples of intermittent sampling need to wait for a long time to build pressure before entering the liquid chromatograph for analysis, so that each chromatographic analysis project can quickly produce a test report, and when the liquid chromatograph is used online with other analyzers, the transmission track will not be blocked due to the long queue of samples of the liquid chromatograph, affecting the sample transmission of other analyzers, thereby fully ensuring the detection efficiency of samples in the online state. In addition, when the lock-release device locks the potential energy storage and release component, since the first drive device for driving the flow of the liquid phase fluid in the liquid phase fluid supply component is in a stopped state, it avoids the undesirable phenomenon of the first drive device continuing to run when there is no sample to be tested, resulting in the loss and waste of liquid phase fluid.

DETAILED DESCRIPTION
[0115] 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 only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of 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.
[0116] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually 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.
[0117] The solution provided in the embodiment of the present application can be applied to the scenario of continuous injection of liquid chromatography equipment (i.e., the sample is concentrated and continuously injected); it can also be applied to the scenario of intermittent injection of liquid chromatography equipment (i.e., the sample is not concentrated and continuously injected), so as to solve the problem of frequent pressure building and pressure relief of liquid chromatography equipment in intermittent injection scenario, resulting in loss of liquid phase fluid, low utilization efficiency, and the problem of slow detection speed and inability to be used online with other analyzers due to the long pressure building process. The liquid chromatography equipment performs elution detection on the sample by liquid chromatography. Liquid chromatography refers to the use of the different affinity such as distribution coefficient and adsorption capacity of various components in the sample in the liquid and solid phases to separate and elute. Due to the differences in properties and structures of the components, the size and strength of the forces generated between the components and the stationary phase are different. As the mobile phase moves, the mixture undergoes repeated distribution equilibrium between the two phases, so that the various components are retained by the stationary phase for different times, thereby flowing out from the stationary phase in a certain order.
[0118] The liquid chromatography device provided in the embodiment of the present application can be a glycated hemoglobin analyzer, or it can be other equipment that uses liquid chromatography, such as a device that combines liquid chromatography with mass spectrometry or a device that uses liquid chromatography to detect urine samples or other non-blood samples. The glycated hemoglobin analyzer provided in the embodiment of the present application uses liquid chromatography to detect glycated hemoglobin. Since in specific applications, there are not many samples that need to be analyzed for glycated hemoglobin, the glycated hemoglobin analyzer generally needs intermittent sampling. Applying the solution of the embodiment of the present application to the glycated hemoglobin analyzer is beneficial for the online use of the glycated hemoglobin analyzer with other analyzers, such as online as a cascade system or an assembly line.
[0119] Example 1:
[0120] As shown in Figures 1 to 11, a sample analysis system 10 provided in the first embodiment of the present application includes a sample input device 400, a first analyzer, a second analyzer, a sample transfer device 300, and a control assembly 500. The sample analysis system 10 is a sample analysis cascade system or a sample analysis pipeline for connecting at least two analyzers. The sample input device 400 is used to receive at least a sample container containing a sample to facilitate sample loading. The sample container is used to hold a sample collected from a patient. The first analyzer is used to draw a sample from the sample container and perform a first analysis on at least a portion of the drawn sample. The second analyzer is used to draw a sample from the sample container and perform a second analysis on at least a portion of the drawn sample. The sample transfer device 300 is used to transfer the sample container from the sample input device 400 to the first analyzer and / or the second analyzer. The control assembly 500 is used to control the sample transfer device 300 to transfer the sample container to the first analyzer and / or the second analyzer.
[0121] As an embodiment, the above-mentioned sample is a sample collected from a human body or an animal body, that is, the sample is a human sample or an animal sample.
[0122] In one embodiment, the sample is a blood sample, and the sample input device 400 is at least used to receive a sample container containing the blood sample to enable loading of the blood sample. Specifically, the sample analysis system 10 in this embodiment is a cascade system or pipeline for analyzing blood samples. Of course, in specific applications, the sample is not limited to a blood sample; for example, a urine sample or other body fluid sample may also be used.
[0123] In one embodiment, the first analyzer is a liquid chromatography device, i.e., the first analysis item is a chromatographic elution analysis item. The liquid chromatography device is used to aspirate a sample from a sample container and perform chromatographic elution and analysis on at least a portion of the aspirated sample. In this embodiment, the liquid chromatography device can be used in conjunction with other analyzers without affecting the detection efficiency of the other analyzers.
[0124] As an embodiment, the liquid chromatography device may be a liquid chromatography analyzer 100, or the liquid chromatography device may be a liquid chromatography-mass spectrometry analyzer 101. The liquid chromatography analyzer 100 uses an ultraviolet detector 160 or a fluorescence detector 160 as the detector 160; the liquid chromatography-mass spectrometry analyzer 101 uses a mass spectrometry detector 160 as the detector 160.
[0125] In one embodiment, the first analyzer is a liquid chromatograph 100, i.e., the first analysis item is a chromatographic analysis item. The liquid chromatograph 100 is configured to draw a sample from a sample container and perform a chromatographic analysis on at least a portion of the drawn sample. In this embodiment, the liquid chromatograph 100 can be used in conjunction with other analyzers without affecting the detection efficiency of the other analyzers.
[0126] As an embodiment, the liquid chromatograph 100 is used to draw a blood sample from a sample container and perform chromatographic analysis on at least a portion of the drawn blood sample. Of course, in specific applications, the liquid chromatograph 100 is not limited to performing chromatographic analysis on blood samples. For example, the liquid chromatograph 100 can also be used to perform chromatographic analysis on urine samples or other samples. That is, the liquid chromatograph 100 can be used to draw a urine sample or other sample from a sample container and perform chromatographic analysis on at least a portion of the drawn urine sample or other sample.
[0127] As an embodiment, the second analyzer is a flow analyzer, which uses an optical detection component to perform optical detection on the optical detection test liquid flowing through the flow chamber.
[0128] As an embodiment, the second analyzer is a cell analyzer, that is, the second analysis item mentioned above is a cell analysis item.
[0129] As an embodiment, the second analyzer is a blood cell analyzer 200, that is, the second analysis item mentioned above is a blood cell analysis item. The blood cell analyzer 200 is also called a routine blood analyzer or a hematology analyzer, and the blood cell analysis item is also called a routine blood analysis item. The blood cell analyzer 200 is used to draw a blood sample from a sample container and perform a blood cell analysis on at least a portion of the drawn blood sample. In specific applications, the demand for blood cell analysis is relatively large. Connecting the liquid chromatography analyzer 100 with the blood cell analyzer 200 is conducive to the chromatographic analysis item and the blood cell analysis item sharing the blood sample in the same sample container, so that the blood sample in one sample container can produce two test results, namely liquid chromatography analysis results and blood cell analysis results, thereby helping to reduce the amount of blood samples collected from patients and reduce the consumption of sample containers.
[0130] As an embodiment, the sample transfer device 300 includes a first transfer track 310 and a second transfer track 320. The first transfer track 310 is used to transfer the sample container from the sample input device 400 to the liquid chromatograph analyzer 100, and the second transfer track 320 is used to transfer the sample container from the sample input device 400 to the hematology analyzer 200. The first transfer track 310 and the second transfer track 320 are integrally formed or interconnected, that is, the first transfer track 310 and the second transfer track 320 can be the same transfer track or two transfer tracks spliced together. The sample transfer device 300 allows the sample container of the sample input device 400 to be automatically transported to the liquid chromatograph analyzer 100 or automatically transferred to the hematology analyzer 200, without the need for manual sorting and transfer of sample containers between the liquid chromatograph analyzer 100 and the hematology analyzer 200, thereby reducing the workload of operators and improving the efficiency of batch sample testing.
[0131] As an embodiment, the sample suction position of the liquid chromatograph analyzer 100 can be inside the machine or on the first transfer track 310 outside the machine. When the sample suction position of the liquid chromatograph analyzer 100 is inside the machine, the liquid chromatograph analyzer 100 has a first sample suction channel inside. The sample container transferred to the side of the liquid chromatograph analyzer 100 by the first transfer track 310 can be dispatched to the sample suction position of the first sample suction channel through the first sample scheduling component.
[0132] As an embodiment, the sample aspiration position of the hematology analyzer 200 can be inside the machine or on the second transfer track 320 outside the machine. When the sample aspiration position of the hematology analyzer 200 is inside the machine, the hematology analyzer 200 has a second sample aspiration channel inside. The sample container transferred to the side of the hematology analyzer 200 by the second transfer track 320 can be dispatched to the sample aspiration position of the second sample aspiration channel through the second sample scheduling component.
[0133] As an embodiment, the sample analysis system 10 further includes an information acquisition device 600, which is configured to acquire information characterizing the type of test item of the blood sample in the sample container. The control component 500 is configured to: determine the type of test item of the blood sample in the sample container based on the information characterizing the type of test item of the blood sample in the sample container fed back by the information acquisition device 600; and, based on the type of test item of the blood sample in the sample container, control the sample transfer device 300 to transfer the sample container to the liquid chromatograph analyzer 100 and / or the blood cell analyzer 200 for sample aspiration. The configuration of the information acquisition device 600 enables the control component 500 to automatically determine which analyzer to transfer the sample container to for analysis based on the information fed back by the information acquisition device 600.
[0134] As an embodiment, the liquid chromatograph analyzer 100 includes a sample supply assembly 110, a liquid-phase fluid supply assembly 120, a reversing valve 130, a test solution preparation channel 140, a chromatographic column 150, and a detector 160. The sample supply assembly 110, the liquid-phase fluid supply assembly 120, the test solution preparation channel 140, and the chromatographic column 150 are respectively connected to different interfaces of the reversing valve 130 through liquid circuits. The reversing valve 130 is mainly used to switch the flow direction of the liquid in the liquid circuit. The sample supply assembly 110 is used to draw a blood sample from a sample container and supply a test solution made from at least a portion of the drawn blood sample to the test solution preparation channel 140 through the reversing valve 130. The liquid-phase fluid supply assembly 120 is used to drive the test solution in the test solution preparation channel 140 to be transported to the chromatographic column 150 through the liquid-phase fluid, and to drive the liquid-phase fluid to flow through the reversing valve 130 and the chromatographic column 150 in sequence. The chromatographic column 150 is used to adsorb the test solution and to provide a liquid phase fluid to elute the test solution to form a test solution. The detector 160 is used to perform chromatographic analysis on the test solution flowing out of the chromatographic column 150 .
[0135] In one embodiment, the reversing valve 130 has a switchable first and second communication states. In the first communication state, the reversing valve 130 connects the sample supply assembly 110 with the test solution preparation channel 140 and connects the liquid-phase fluid supply assembly 120 with the chromatographic column 150. In the second communication state, the reversing valve 130 connects the liquid-phase fluid supply assembly 120, the test solution preparation channel 140, and the chromatographic column 150, with the chromatographic column 150 connected between the reversing valve 130 and the detector 160. The reversing valve 130 can be switched between the first and second communication states under the control of the control assembly 500. In the first communication state, the sample supply assembly 110 can drive the test solution into the test solution preparation channel 140, and the liquid-phase fluid supply assembly 120 can drive the liquid-phase fluid into the chromatographic column 150. In the second communication state, the liquid-phase fluid supply assembly 120 can drive the liquid-phase fluid to transport the test solution in the test solution preparation channel 140 to the chromatographic column 150, while the sample supply assembly 110 cannot drive the test solution into the test solution preparation channel 140.
[0136] As an embodiment, the liquid-phase fluid supply assembly 120 includes a first driving device 121 and an energy storage device 122. The first driving device 121 is used to drive the liquid-phase fluid to flow toward the reversing valve 130 and the chromatographic column 150. The energy storage device 122 is arranged between the first driving device 121 and the reversing valve 130. The energy storage device 122 is used to store potential energy and release the stored potential energy. In this embodiment, by providing the energy storage device 122 in the liquid-phase fluid supply assembly 120, the liquid-phase fluid supply assembly 120 not only has the function of providing a liquid-phase fluid of a certain pressure, but also has the function of storing potential energy and releasing potential energy.
[0137] As an embodiment, the liquid-phase fluid supply assembly 120 further includes a locking and releasing device 123, which is used to lock and release the energy storage device 122. The locking and releasing device 123 can switch between a locked state and a released state. In a specific application, when the locking and releasing device 123 is in the released state, the energy storage device 122 can store potential energy under the pressure of the liquid-phase fluid; when the locking and releasing device 123 is in the locked state, the energy storage device 122 is locked and the potential energy stored in the energy storage device 122 cannot be released; when the locking and releasing device 123 switches from the locked state to the released state, the potential energy stored in the energy storage device 122 can be released. In this embodiment, an energy storage device 122 and a locking and releasing device 123 are provided in the liquid-phase fluid supply component 120, and the locking and releasing device 123 is provided to release the potential energy storage and release component 1222 of the energy storage device 122 in the released state to allow the energy storage device 122 to store and release potential energy under the pressure of the liquid-phase fluid, and the locking and releasing device 123 is provided to lock the potential energy storage and release component 1222 in the locked state to prevent the energy storage device 122 from releasing the stored potential energy, so that the liquid-phase fluid supply component 120 has the function of storing and releasing potential energy in addition to providing liquid-phase fluid of a certain pressure.
[0138] As an embodiment, the energy storage device 122 includes a shell 1221 and a potential energy storage and release component 1222. The potential energy storage and release component 1222 is at least partially disposed in the shell 1221 and is separated in the shell 1221 to form a liquid cavity 1223 for liquid phase fluid to flow through. The potential energy storage and release component 1222 is at least partially capable of moving relative to the shell 1221 to change the size of the liquid cavity 1223 and store potential energy or release the stored potential energy.
[0139] In one embodiment, the locking and releasing device 123 can switch between a locked state and a released state: in the locked state, the locking and releasing device 123 applies a force to the potential energy storage and release component 1222 to lock the potential energy storage and release component 1222, thereby preventing the potential energy storage and release component 1222 from moving relative to the housing 1221 and releasing the stored potential energy. In the released state, the potential energy storage and release component 1222 can move relative to the housing 1221 under the pressure of the liquid fluid to store potential energy. When the locking and releasing device 123 removes the force applied to the potential energy storage and release component 1222, the potential energy storage and release component 1222 is released, thereby allowing the potential energy storage and release component 1222 to move relative to the housing 1221 and release the stored potential energy. In this embodiment, the locking and releasing device 123 locks the potential energy storage and release component 1222 by directly applying a force to the potential energy storage and release component 1222.
[0140] As an embodiment, the control component 500 is further configured to: during the execution of a chromatographic analysis project of a sample (for ease of distinction, it can also be described as the current sample or the previous sample), control the first driving device 121 to drive the liquid phase fluid to flow to elute the test solution adsorbed on the chromatographic column 150, and control the energy storage device 122 to store potential energy through the pressure of the liquid phase fluid; after completing the chromatographic analysis project of a sample (the previous sample), and when executing the chromatographic analysis project of the next sample, control the energy storage device 122 to release the potential energy stored during the execution of the chromatographic analysis project of a sample (the previous sample) to assist in driving the liquid phase fluid to flow toward the reversing valve 130 and the chromatographic column 150. This embodiment utilizes the potential energy stored in the energy storage device 122 to reduce energy loss and liquid fluid loss; and utilizes the potential energy released by the energy storage device 122 to assist in rapidly building pressure of the liquid fluid, thereby accelerating the speed of re-building pressure for the next sample. This avoids the problem of the next sample having to wait for a long time for pressure building before entering the liquid chromatograph analyzer 100 for analysis. As a result, each chromatographic analysis project can quickly generate a test report. Furthermore, when the liquid chromatograph analyzer 100 is used online with other analyzers, the transmission track will not be blocked due to the long queueing of samples of the liquid chromatograph analyzer 100, which will affect the sample transmission of other analyzers. This fully ensures the detection efficiency of samples in the online state.
[0141] As an embodiment, the above-mentioned control of the energy storage device 122 to store potential energy through the pressure of the liquid-phase fluid includes: controlling the lock-release device 123 to be in a released state to allow the energy storage device 122 to store potential energy through the pressure of the liquid-phase fluid. The above-mentioned control of the energy storage device 122 to release the potential energy stored in the process of executing the chromatographic analysis project of a sample after completing the chromatographic analysis project of a sample and when executing the chromatographic analysis project of the next sample includes: after completing the chromatographic analysis project of a sample, controlling the lock-release device 123 to switch from the released state to the locked state to prevent the energy storage device 122 from releasing the stored potential energy, and controlling the first driving device 121 to stop driving the liquid-phase fluid to flow; after the lock-release device 123 switches to the locked state, when executing the chromatographic analysis project of the next sample, controlling the lock-release device 123 to switch from the locked state to the released state to allow the energy storage device 122 to release the potential energy stored in the process of executing the chromatographic analysis project of a sample. In this embodiment, after completing the chromatographic analysis project of a sample, the locking device 123 is switched from the released state to the locked state to prevent the energy storage device 122 from releasing the stored potential energy, thereby achieving the effect of storing energy and maintaining pressure. When executing the chromatographic analysis project of the next sample, the energy stored in the previous sample can be used to assist the liquid phase fluid in quickly building up pressure; of course, in specific applications, as an alternative implementation scheme, when two adjacent samples are continuously injected or the injection interval is very small (for example, less than the first preset time length described below), the pressure can also be maintained by controlling the first driving device 121 to keep driving the liquid phase fluid to flow, without the need for the locking device 123 to switch from the released state to the locked state, but this may result in a large consumption of the liquid phase fluid.
[0142] As an embodiment, the control component 500 is further configured to: during the execution of the chromatographic analysis project, control the first driving device 121 to drive the liquid phase fluid to elute the test solution adsorbed on the chromatographic column 150, control the locking and releasing device 123 to be in a released state to allow the potential energy storage and release component 1222 to move relative to the shell 1221 under the pressure of the liquid phase fluid to store potential energy; within a first preset time after the completion of the chromatographic analysis project of a blood sample, if no information is obtained that there are other blood samples that need to perform chromatographic analysis projects, then control the locking and releasing device 123 to be released from the state. The state is switched to the locked state to prevent the potential energy storage and release component 1222 from moving relative to the shell 1221, thereby preventing the potential energy storage and release component 1222 from releasing the stored potential energy, and controlling the first driving device 121 to stop driving the liquid phase fluid to flow; after the locking and releasing device 123 is switched to the locked state, if information is obtained that a blood sample needs to perform a chromatographic analysis project, the locking and releasing device 123 is controlled to switch from the locked state to the released state, so that the potential energy storage and release component 1222 can move relative to the shell 1221 and release the stored potential energy to assist in driving the liquid phase fluid to flow toward the reversing valve 130 and the chromatographic column 150. In this embodiment, the potential energy stored in the energy storage device 122 is used to reduce energy loss in the intermittent injection scenario; the potential energy released by the energy storage device 122 is used to assist in the rapid pressure buildup of the liquid phase fluid, thereby accelerating the speed of re-building pressure in the intermittent injection scenario, thereby avoiding the problem that the intermittently injected blood samples need to wait for a long time to build pressure before entering the liquid chromatograph analyzer 100 for analysis, so that each chromatographic analysis project can quickly produce a test report, and when the liquid chromatograph analyzer 100 is used online with other analyzers, the blood samples of the liquid chromatograph analyzer 100 are not queued for a long time, resulting in the blockage of the transmission track and affecting the sample transmission of other analyzers, thereby fully ensuring the detection efficiency of the samples in the online state. In addition, when the lock and release device 123 locks the potential energy storage and release component 1222, since the first drive device 121 for driving the flow of the liquid phase fluid in the liquid phase fluid supply component 120 is in a stopped state, the first drive device 121 is prevented from continuing to operate when there is no blood sample to perform the chromatographic analysis project test, resulting in the waste of liquid phase fluid.
[0143] As an embodiment, the control component 500 is further configured to: during the execution of the chromatographic analysis project, control the first driving device 121 to drive the liquid phase fluid to elute the test solution adsorbed on the chromatographic column 150, control the locking and releasing device 123 to be in a released state to allow the potential energy storage and release component 1222 to move relative to the shell 1221 under the pressure of the liquid phase fluid to store potential energy; within a first preset time after the completion of the chromatographic analysis project of a blood sample, if no information is obtained that there are other blood samples that need to perform chromatographic analysis projects, then control the locking and releasing device 123 to be released from the state. The state is switched to the locked state to prevent the potential energy storage and release component 1222 from moving relative to the shell 1221, thereby preventing the potential energy storage and release component 1222 from releasing the stored potential energy, and controlling the first driving device 121 to stop driving the liquid phase fluid to flow; after the locking and releasing device 123 is switched to the locked state, if information is obtained that a blood sample needs to perform a chromatographic analysis project, the locking and releasing device 123 is controlled to switch from the locked state to the released state, so that the potential energy storage and release component 1222 can move relative to the shell 1221 and release the stored potential energy to assist in driving the liquid phase fluid to flow toward the reversing valve 130 and the chromatographic column 150. In this embodiment, the potential energy stored in the energy storage device 122 is used to reduce energy loss in the intermittent injection scenario; the potential energy released by the energy storage device 122 is used to assist in the rapid pressure buildup of the liquid phase fluid, thereby accelerating the speed of re-building pressure in the intermittent injection scenario, thereby avoiding the problem that the intermittently injected blood samples need to wait for a long time to build pressure before entering the liquid chromatograph analyzer 100 for analysis, so that each chromatographic analysis project can quickly produce a test report, and when the liquid chromatograph analyzer 100 is used online with other analyzers, the blood samples of the liquid chromatograph analyzer 100 are not queued for a long time, resulting in the blockage of the transmission track and affecting the sample transmission of other analyzers, thereby fully ensuring the detection efficiency of the samples in the online state. In addition, when the lock and release device 123 locks the potential energy storage and release component 1222, since the first drive device 121 for driving the flow of the liquid phase fluid in the liquid phase fluid supply component 120 is in a stopped state, the first drive device 121 is prevented from continuing to operate when there is no blood sample to perform the chromatographic analysis project test, resulting in the waste of liquid phase fluid.
[0144] In one embodiment, the potential energy stored and released by the potential energy storage and release assembly 1222 is elastic potential energy. Specifically, the assembly converts part of the pressure energy of the liquid fluid into elastic potential energy by driving the deformation of an elastic component, storing it and releasing it when needed. This simple structure and low cost are key features. By storing and releasing elastic potential energy, the assembly can also eliminate pressure or flow pulsations in the liquid fluid within the pipeline. Of course, in specific applications, the configuration of the potential energy storage and release component 1222 is not limited to this. For example, as an alternative embodiment, the potential energy stored and released by the potential energy storage and release component 1222 is gravitational potential energy, and it converts the pressure energy of the liquid fluid into gravitational potential energy and accumulates it by lifting the mass block loaded on the sealing piston; or, as another alternative embodiment, the potential energy stored and released by the potential energy storage and release component 1222 is gas internal energy, and energy conversion is completed by compressing the gas. When in use, gas with a predetermined pressure is first filled into the energy storage device 122. When the pressure of the liquid fluid exceeds the pressure inside the energy storage device 122, the liquid fluid compresses the gas and converts the pressure of the liquid fluid into gas internal energy; when the pressure of the liquid fluid is lower than the pressure inside the energy storage device 122, the liquid fluid in the energy storage device 122 flows out of the energy storage device 122 under the action of the high-pressure gas to release energy.
[0145] As an embodiment, the locking and releasing device 123 applies a force to the potential energy storage and release assembly 1222 to lock the potential energy storage and release assembly 1222 in a non-liquid path locking manner, and the locking and releasing device 123 removes the force applied to the potential energy storage and release assembly 1222 in a non-liquid path conduction manner to release the potential energy storage and release assembly 1222. In this embodiment, the locking and releasing device 123 is not connected to the energy storage device 122 via a liquid path, but rather locks and releases the potential energy storage and release assembly 1222 of the energy storage device 122 through a mechanical structure. In this way, the provision of the locking and releasing device 123 does not affect the original liquid path system of the liquid chromatograph analyzer 100.
[0146] As an embodiment, the locking and releasing device 123 applies a force to the potential energy storage and release component 1222 by abutting against the potential energy storage and release component 1222 to lock the potential energy storage and release component 1222, and the locking and releasing device 123 removes the force applied to the potential energy storage and release component 1222 by separating from the potential energy storage and release component 1222 to release the potential energy storage and release component 1222. In this embodiment, the locking and releasing device 123 locks and limits the potential energy storage and release component 1222 by directly contacting the potential energy storage and release component 1222, and releases the limit on the potential energy storage and release component 1222 by separating from the potential energy storage and release component 1222. Of course, in specific applications, as an alternative embodiment, the locking and releasing device 123 can also apply a force to the potential energy storage and release component 1222 to lock the potential energy storage and release component 1222 by non-contacting the potential energy storage and release component 1222, for example, by magnetic attraction.
[0147] As an embodiment, the potential energy storage and release assembly 1222 has a latching portion 1222d extending outside the housing 1221. The locking and releasing device 123 applies a force to the potential energy storage and release assembly 1222 by limiting the latching portion 1222d, thereby locking the potential energy storage and release assembly 1222. The locking and releasing device 123 removes the force applied to the potential energy storage and release assembly 1222 by releasing the latching portion 1222d, thereby releasing the potential energy storage and release assembly 1222. In this embodiment, the locking and releasing device 123 locks the potential energy storage and release assembly 1222 by limiting the latching portion 1222d extending outside the housing 1221, eliminating the need to machine a structure that cooperates with the locking and releasing device 123 on the housing 1221, thereby simplifying the structure of the energy storage device 122. Of course, in a specific application, as an alternative implementation scheme, the locking and releasing device 123 can also be set to be inserted into the shell 1221 to lock and limit the potential energy storage and release component 1222.
[0148] In one embodiment, the locking and releasing device 123 includes a power component 1231, a locking component 1232, and a transmission component 1233 that is transmission-connected between the power component 1231 and the locking component 1232. The power component 1231 is used to drive the transmission component 1233, which in turn drives the locking component 1232, thereby moving the locking component 1232 between a locked position and an unlocked position. In the locked position, the locking component 1232 abuts the potential energy storage and release assembly 1222 to lock the potential energy storage and release assembly 1222. In the unlocked position, the locking component 1232 disengages from the potential energy storage and release assembly 1222 to release the potential energy storage and release assembly 1222.
[0149] As an embodiment, when the locking and releasing device 123 is in a locked state, the locking component 1232 is in a locked position to lock the potential energy storage and release assembly 1222 .
[0150] As an embodiment, the transmission component 1233 has a self-locking capability. When the lock-release device 123 is in the locked state, the power component 1231 is in a stopped state, and the locking component 1232 is in a locked position by the locking force generated by the self-locking of the transmission component 1233, thereby locking the potential energy storage and release assembly 1222. In this embodiment, the self-locking of the transmission component 1233 allows the locking component 1232 to maintain the state of locking the potential energy storage and release assembly 1222, without the need for the power component 1231 to provide power locking. The power component 1231 is only used to drive the transmission component 1233 to drive the locking component 1232 between the locked position and the unlocked position, thereby reducing the load requirement of the power component 1231 and thus helping to reduce the cost of the lock-release device 123.
[0151] As an embodiment, the power component 1231 is a motor; when the locking and releasing device 123 is in a locked state, the motor is in a stopped state, and the locking component 1232 is in a locked position by the locking force generated by the self-locking of the transmission component 1233 to lock the potential energy storage and release component 1222; when the locking and releasing device 123 is in a released state, the motor is in a stopped state, and the locking component 1232 is in an unlocked position to release the potential energy storage and release component 1222; in the process of the locking and releasing device 123 switching from the locked state to the released state, the motor is in a running state to drive the locking component 1232 to move from the locked position to the unlocked position through the transmission component 1233; in the process of the locking and releasing device 123 switching from the released state to the locked state, the motor is in a running state to drive the locking component 1232 to move from the unlocked position to the locked position through the transmission component 1233.
[0152] As an embodiment, the potential energy storage and release component 1222 has a locking portion 1222d extending outside the shell 1221, and the locking portion 1222d has a locking end face facing the liquid chamber 1223; the locking component 1232 is formed with a locking portion 1232a, and the locking portion 1232a is used to move between a locked position and an unlocked position under the drive of the power component 1231 and the transmission component 1233.
[0153] As an embodiment, the above-mentioned control of the locking and releasing device 123 to switch to a locked state to prevent the energy storage device 122 from releasing the stored potential energy includes: controlling the power component 1231 to start and run to drive the transmission component 1233 to drive the locking portion 1232a to move from the unlocked position to the locked position, so that the locking portion 1232a abuts against the locking end face; after the locking portion 1232a moves to the locked position, controlling the power component 1231 to stop running so that the locking portion 1232a remains in the locked position under the action of the locking force generated by the self-locking of the transmission component 1233.
[0154] As an embodiment, the above-mentioned control of the locking and releasing device 123 switches from a locked state to a released state, so that the energy storage device 122 releases the stored potential energy, including: controlling the power component 1231 to start and run, so as to drive the transmission component 1233 to drive the locking portion 1232a to move from the locked position to the unlocked position, so that the locking portion 1232a disengages from the locking end face, thereby causing the potential energy storage and release component 1222 to release the stored potential energy and move toward the liquid cavity 1223, so as to drive the liquid phase fluid in the liquid cavity 1223 to flow out of the liquid cavity 1223.
[0155] As an embodiment, the locking and releasing device 123 also includes a detection component 1234, and the control component 500 is further configured to: obtain feedback information from the detection component 1234 during the process of the power component 1231 driving the transmission component 1233 to drive the locking part 1232a to move from the unlocking position to the locking position; when it is determined based on the feedback information of the detection component 1234 that the locking part 1232a has moved to the locking position, the power component 1231 is controlled to stop running.
[0156] As an embodiment, the detection component 1234 is a reflective photoelectric sensor, a through-beam photoelectric sensor, or a proximity switch.
[0157] As an embodiment, the potential energy stored and released by the potential energy storage and release component 1222 is elastic potential energy; the potential energy storage and release component 1222 includes a diaphragm 1222a, an elastic element 1222b and a guide rod 1222c, the diaphragm 1222a is arranged in the shell 1221, and cooperates with the inner wall of the shell 1221 to form a liquid cavity 1223, one end of the guide rod 1222c is connected to the diaphragm 1222a, and the other end of the guide rod 1222c extends to the outside of the shell 1221 and forms a locking portion 1222d, and the elastic element 1222b is located in the shell 1221 and is sleeved on the guide rod 1222c. When the locking device 123 is in a locked state, it includes: the locking portion 1232a abuts the locking portion 1222d to lock the locking portion 1222d, thereby allowing the elastic element 1222b to store elastic potential energy; when the locking device 123 is in a released state, it includes: the locking portion 1232a disengages from the locking portion 1222d to release the locking portion 1222d, thereby allowing the elastic element 1222b to release the elastic potential energy.
[0158] As an embodiment, when the locking and releasing device 123 is in a released state, the guide rod 1222c can overcome the force of the elastic element 1222b under the action of the pressure of the liquid phase fluid and move in the direction away from the liquid cavity 1223, and can move in the direction close to the liquid cavity 1223 under the action of the elastic element 1222b; when the locking and releasing device 123 is in a locked state, the guide rod 1222c can overcome the force of the elastic element 1222b under the action of the pressure of the liquid phase fluid and move in the direction away from the liquid cavity 1223, but cannot move in the direction close to the liquid cavity 1223 under the action of the elastic element 1222b.
[0159] As an implementation manner, the first driving device 121 may be a plunger pump.
[0160] As an implementation manner, the energy storage device 122 can smooth the pulse flow output by the first driving device 121 through the elastic element 1222b, thereby reducing flow fluctuation.
[0161] As an embodiment, the diaphragm 1222a is a diaphragm made of elastic material, the periphery of which is sealed and fixed, and a rod is embedded in the center, and the rod is connected to or integrally formed with the guide rod 1222c.
[0162] As an embodiment, the stiffness of the elastic element 1222b is greater than or equal to 500 N / mm and less than or equal to 30,000 N / mm.
[0163] As an embodiment, the elastic element 1222b includes at least one pair of disc spring groups. The disc springs have high elasticity and can meet the requirement of providing a large driving force for the liquid phase fluid.
[0164] As an embodiment, the transmission component 1233 includes a screw transmission pair, and the thread lead angle of the screw transmission pair is smaller than the equivalent friction angle.
[0165] In one embodiment, transmission component 1233 includes a lead screw transmission pair, which is a trapezoidal lead screw transmission pair. In this embodiment, the motor torque only needs to be sufficient to drive the locking component 1232 to move under no-load conditions, and does not need to overcome the force of the elastic element 1222b. Therefore, in this embodiment, the motor output torque can be set to be much smaller than the torque required to pull the deformed elastic element 1222b.
[0166] As an embodiment, the screw drive pair includes a screw and a nut, the nut is connected to the screw, and the nut is connected to the guide shaft, the function of the guide shaft is to convert the rotational motion of the nut into linear motion. The locking component 1232 is connected to the nut of the screw pair. The screw drive pair of this embodiment is a trapezoidal screw drive pair with a self-locking function, which meets the self-locking condition that the thread lead angle is less than the equivalent friction angle. The output shaft of the motor is fixedly connected to the screw to provide power for the rotation of the screw.
[0167] As an embodiment, the detection component 1234 is an optical coupler fixed on the base. The locking component 1232 is connected to an optical coupler block.
[0168] As an embodiment, the working principle of the energy storage device 122 and the locking and releasing device 123 is as follows: when high-pressure liquid fluid flows into the energy storage device 122, the diaphragm 1222a deforms toward the side where the elastic element 1222b is located under the pressure of the liquid fluid. The load is transmitted to the elastic element 1222b by the guide rod 1222c, converting the pressure potential energy of the liquid fluid into the elastic potential energy of the elastic element 1222b. At the same time, the guide rod 1222c moves in a direction away from the liquid cavity 1223. In this embodiment, the locking portion 1232a pulls the locking portion 1222d of the extended guide rod 1222c, preventing it from rebounding under the action of the elastic element 1222b, thereby allowing the elastic element 1222b to retain its elastic potential energy. When the locking and releasing device 123 is in the initial position, the diaphragm 1222a of the energy storage device 122 is not deformed, and the elastic element 1222b in the energy storage device 122 is in the initial state (with pre-pressure or without force). When the energy storage device 122 is operating, the diaphragm 1222a deforms away from the liquid chamber 1223, causing the guide rod 1222c to move toward the elastic element 1222b. This displacement fluctuates within a small range as the pulsed flow of the liquid phase fluid is input. When the energy storage device 122 stops operating, the pressure slowly decreases due to system damping. At this point, the guide rod 1222c gradually moves toward the liquid chamber 1223 under the action of the elastic element 1222b. At this point, the motor of the locking and releasing device 123 rotates, driving the locking component 1232 away from the liquid chamber 1223 until the locking portion 1232a contacts the retaining portion 1222d of the guide rod 1222c. At this point, the motor drives locking member 1232 to move a certain distance away from liquid chamber 1223 and then stops. This distance is greater than the maximum rightward movement distance of guide rod 1222c. Because the motor's torque is insufficient to overcome the force of elastic element 1222b, it does not pull guide rod 1222c excessively to the right, potentially causing the motor to stall briefly. Due to the self-locking effect of the screw drive pair, guide rod 1222c does not continue to move leftward under the action of elastic element 1222b, but instead remains in this state. At this point, the liquid in liquid chamber 1223, without the effect of additional load, only flows out in small amounts, thereby reducing liquid phase fluid consumption. The next time pressure is built up, only a small amount of liquid phase fluid is needed to fill liquid chamber 1223, reducing pressure buildup time. Simultaneously, after the hydraulic system completes pressure buildup, pressure causes guide rod 1222c to move rightward again and disengage from locking member 1232. The motor then drives locking member 1232 back to its initial position, allowing it to lock guide rod 1222c again.
[0169] As an embodiment, if information is obtained that a chromatographic analysis project needs to be performed on a blood sample, the locking and releasing device 123 is controlled to switch from a locked state to a released state, including: if information is obtained that a chromatographic analysis project needs to be performed on a blood sample, the first driving device 121 is first controlled to start and run, and then the locking and releasing device 123 is controlled to switch from a locked state to a released state. In this embodiment, before the locking and releasing device 123 is switched from the locked state to the released state, the first driving device 121 is first controlled to start and run so that the liquid phase fluid has a certain pressure, thereby avoiding the undesirable phenomenon that the potential energy is completely released when the locking and releasing device 123 switches from the locked state to the released state, resulting in the need for a larger pressure to re-drive the potential energy storage and release component 1222 to expand.
[0170] As an embodiment, the control component 500 is further configured to: during the execution of a chromatographic analysis project, control the first drive device 121 to drive the liquid-phase fluid to flow at a target pressure value or a pressure value within a target pressure range to elute the test solution adsorbed on the chromatographic column 150; and before executing the first chromatographic analysis project after the liquid chromatograph 100 is powered on, first control the first drive device 121 to start and maintain operation for a third preset time period so that the pressure of the liquid-phase fluid flowing to the chromatographic column 150 reaches the target pressure value or the target pressure range. The third preset time period is the pressure buildup time before the execution of the first chromatographic analysis project after the liquid chromatograph 100 is powered on, that is, the time it takes for the pressure of the liquid-phase fluid in the liquid circuit system to increase from zero to the target pressure value or the target pressure range.
[0171] As an embodiment, the target pressure value is greater than or equal to 2 MPa and less than or equal to 10 MPa.
[0172] As an embodiment, the target pressure value is greater than or equal to 4 MPa and less than or equal to 6 MPa.
[0173] As an embodiment, the above-mentioned control of the first driving device 121 to start and run, and then controlling the lock-release device 123 to switch from the locked state to the released state includes: first controlling the first driving device 121 to start and keep running for a second preset time, so that the pressure of the liquid-phase fluid flowing to the chromatographic column 150 is greater than zero and less than the target pressure value or less than the lower limit of the target pressure range, and then controlling the lock-release device 123 to switch from the locked state to the released state. The control component 500 is also configured to: after controlling the lock-release device 123 to switch from the locked state to the released state, first control the first driving device 121 to continue to run for a fourth preset time, so that the pressure of the liquid-phase fluid flowing to the chromatographic column 150 approximately reaches the target pressure value or the target pressure range, and then control the reversing valve 130 to switch to the second connected state, so that the liquid-phase fluid supply component 120 drives the test solution in the test solution preparation channel 140 to be delivered to the chromatographic column 150 through the liquid-phase fluid; wherein the sum of the second preset time and the fourth preset time is less than the third preset time. The sum of the second preset time and the fourth preset time is the pressure buildup time during the intermittent sampling process. In this embodiment, the potential energy stored in the energy storage device 122 assists the pressure buildup drive during the intermittent sampling process, thereby shortening the pressure buildup time during the intermittent sampling process.
[0174] Preferably, the sum of the second preset time length and the fourth preset time length is less than half of the third preset time length.
[0175] Preferably, the sum of the second preset time length and the fourth preset time length is less than or equal to one tenth of the third preset time length.
[0176] As an embodiment, the housing 1221 is formed with a liquid inlet 1221a for supplying liquid-phase fluid into the liquid chamber 1223 and a liquid outlet 1221b for supplying liquid-phase fluid out of the liquid chamber 1223; after the control lock-release device 123 is switched to the locked state and the first driving device 121 is controlled to stop driving the liquid-phase fluid flow, and before the control first driving device 121 is started and the control lock-release device 123 is switched from the locked state to the released state, the pressure value of the liquid-phase fluid at the liquid outlet 1221b is a first pressure value; after the first driving device 121 is started and maintained in operation for a second preset time period, and during the process of the lock-release device 123 switching from the locked state to the released state, the pressure value of the liquid-phase fluid at the liquid outlet 1221b is a second pressure value; after the lock-release device 123 is switched from the locked state to the released state, the pressure value of the liquid-phase fluid at the liquid outlet 1221b is a third pressure value. Wherein, the second pressure value is greater than the first pressure value and greater than the third pressure value. In this embodiment, during the process of intermittent injection and re-building pressure, the pressure of the liquid phase fluid first increases and then decreases under the auxiliary driving force of the potential energy released by the energy storage device 122, thereby facilitating the purpose of rapid pressure building.
[0177] As an embodiment, the first pressure value is less than the target pressure value or less than the lower limit of the target pressure range; the second pressure value is greater than the target pressure value or greater than the upper limit of the target pressure range; the third pressure value is approximately equal to the target pressure value or falls within the target pressure range.
[0178] As an embodiment, after the control lock-release device 123 switches to the locked state and the first drive device 121 stops driving the flow of the liquid phase fluid, and before the control first drive device 121 starts and the control lock-release device 123 switches from the locked state to the released state, the volume of the liquid chamber 1223 is the first volume; after the first drive device 121 starts and keeps running for a second preset time, and before the lock-release device 123 switches from the locked state to the released state, the volume of the liquid chamber 1223 is the second volume; after the lock-release device 123 switches from the locked state to the released state, the volume of the liquid chamber 1223 is the third volume; wherein, the second volume is greater than the first volume and greater than the third volume. In this embodiment, in the process of intermittent sampling and re-building pressure, the volume of the liquid chamber 1223 first increases and then decreases, which is conducive to achieving the purpose of rapid pressure building.
[0179] As an embodiment, the first volume is less than or approximately equal to the volume of the liquid cavity 1223 during the execution of the chromatographic analysis project, the second volume is greater than the volume of the liquid cavity 1223 during the execution of the chromatographic analysis project, and the third volume is approximately equal to the volume of the liquid cavity 1223 during the execution of the chromatographic analysis project.
[0180] As an embodiment, after controlling the locking and releasing device 123 to switch to the locked state and controlling the first driving device 121 to stop driving the flow of the liquid phase fluid, and before controlling the first driving device 121 to start running and controlling the locking and releasing device 123 to switch from the locked state to the released state, the potential energy stored in the energy storage device 122 is the first potential energy; after controlling the first driving device 121 to start and keep running for a second preset time, and before controlling the locking and releasing device 123 to switch from the locked state to the released state, the potential energy stored in the energy storage device 122 is the second potential energy; after the locking and releasing device 123 switches from the locked state to the released state, the potential energy stored in the energy storage device 122 is the third potential energy; wherein, the second potential energy is greater than the first potential energy and greater than the third potential energy.
[0181] As an embodiment, the first potential energy is less than or approximately equal to the potential energy stored in the energy storage device 122 during the execution of the chromatographic analysis project, the first potential energy is greater than the potential energy stored in the energy storage device 122 during the execution of the chromatographic analysis project, and the third potential energy is approximately equal to the potential energy stored in the energy storage device 122 during the execution of the chromatographic analysis project.
[0182] As an embodiment, the energy storage device 122 has a liquid inlet 1221a for supplying liquid-phase fluid to flow in and a liquid outlet 1221b for supplying liquid-phase fluid to flow out; after the control lock-release device 123 is switched to the locked state and the first drive device 121 is controlled to stop driving the flow of the liquid-phase fluid, and before the control first drive device 121 is started and the control lock-release device 123 is switched from the locked state to the released state, the pressure value of the liquid-phase fluid at the liquid outlet 1221b is a first pressure value; the first pressure value is approximately zero. In this embodiment, when the first drive device 121 stops driving the flow of the liquid-phase fluid and the energy storage device 122 is in the locked state, the pressure value of the liquid-phase fluid is approximately zero, which helps to reduce the loss of the liquid circuit device components caused by maintaining high pressure in the liquid circuit for a long time.
[0183] As an embodiment, within the first preset time period after the completion of a chromatographic analysis project of a blood sample, if no other blood samples are obtained that need to be subjected to the chromatographic analysis project, the locking device 123 is controlled to switch to a locked state, and the first driving device 121 is controlled to stop driving the liquid-phase fluid to flow, including: within the first preset time period after the completion of a chromatographic analysis project of a blood sample, if no information is obtained that other blood samples need to be subjected to the chromatographic analysis project, the locking device 123 is first controlled to switch to a locked state, and then the first driving device 121 is controlled to stop driving the liquid-phase fluid to flow. In this embodiment, when it is necessary to lock the energy storage device 122 to lock potential energy, the locking device 123 is first controlled to switch to a locked state, and then the first driving device 121 is controlled to stop running. In this way, when the locking device 123 switches to a locked state, the pressure of the liquid-phase fluid prevents the energy storage device 122 from releasing potential energy, thereby better locking the potential energy of the energy storage device 122. Of course, in specific applications, the control sequence of the locking and releasing device 123 and the first driving device 121 is not limited to this. For example, as an alternative implementation scheme, within the first preset time after the completion of the chromatographic analysis project of a blood sample, if no information is obtained that there are other blood samples that need to perform chromatographic analysis projects, the locking and releasing device 123 is controlled to switch to a locked state, and the first driving device 121 is controlled to stop driving the liquid-phase fluid flow; or, as another alternative implementation scheme, within the first preset time after the completion of the chromatographic analysis project of a blood sample, if no information is obtained that there are other blood samples that need to perform chromatographic analysis projects, the first driving device 121 is first controlled to stop driving the liquid-phase fluid flow, and then the locking and releasing device 123 is controlled to switch to a locked state.
[0184] As an embodiment, the control component 500 is further configured to: control the sample supply component 110 to perform the following test solution preparation actions within a fifth preset time: draw the blood sample from the sample container and distribute it to the first reaction container 112, and transport the test solution made of at least the blood sample and the hemolytic agent in the first reaction container 112 to the sample preparation channel through the reversing valve 130; when the lock and release device 123 is in a locked state, if information is obtained that a blood sample needs to be subjected to a chromatographic analysis project, control the liquid phase fluid supply component 120 to perform the following test solution preparation actions within a sixth ... The following pressure-building action: control the first driving device 121 to start and run, control the lock-release device 123 to switch from the locked state to the released state, so that the pressure of the liquid-phase fluid supply component 120 driving the liquid-phase fluid to flow to the chromatographic column 150 reaches the target pressure value or the target pressure range within the sixth preset time; in the process of executing the chromatographic analysis project, control the first driving device 121 to drive the liquid-phase fluid to flow at the target pressure value or the pressure value within the target pressure range to elute the test solution adsorbed on the chromatographic column 150; wherein the sixth preset time is less than the fifth preset time. The sixth preset time is equal to the sum of the second preset time and the fourth preset time. In this embodiment, in the intermittent scenario, the time for re-building pressure is less than the time for preparing the test solution, which is conducive to making the re-building pressure and the preparation of the test solution can be carried out simultaneously.
[0185] As an embodiment, the control component 500 is also configured to: when the locking and releasing device 123 is in a locked state and the reversing valve 130 is in a first connected state, if information is obtained that a blood sample needs to perform a chromatographic analysis project, the sample supply component 110 is controlled to perform the following test solution preparation action: the blood sample is drawn from the sample container and distributed to the first reaction container 112, and the test solution made of at least the blood sample and the hemolytic agent in the first reaction container 112 is transported to the sample preparation channel through the reversing valve 130; in the process of the sample supply component 110 performing the test solution preparation action, the first driving device 121 is controlled to start and run, the locking and releasing device 123 is controlled to switch from the locked state to the released state, and the reversing valve 130 is controlled to remain in the first connected state; after the sample supply component 110 completes the test solution preparation action, the reversing valve 130 is controlled to switch from the first connected state to the second connected state, so that the liquid-phase fluid supply component 120 drives the test solution in the test solution preparation channel 140 to be transported to the chromatographic column 150 through the liquid-phase fluid. In this embodiment, when a blood sample that needs to be subjected to a chromatographic analysis project is transferred to the liquid chromatograph analyzer 100, the test solution preparation action can be performed directly without waiting, thereby achieving the effect of immediate testing of the blood sample at the liquid chromatograph analyzer 100, and effectively avoiding the undesirable phenomenon of sample containers queuing on the transfer track causing blockage of the transfer track.
[0186] As an embodiment, the control component 500 is further configured to: when the lock-release device 123 is continuously locked for a seventh preset time period, if no information is obtained that a blood sample requires a chromatographic analysis project, control the lock-release device 123 to switch from the locked state to the released state, so that the energy storage device 122 releases stored potential energy; the seventh preset time period is greater than the time required to complete a chromatographic analysis project and greater than the first preset time period. This embodiment, by limiting the length of time that the lock-release device 123 continuously locks the energy storage device 122, helps avoid the undesirable phenomenon of the potential energy storage and release component 1222 being subjected to long-term deformation, which affects its lifespan.
[0187] As an embodiment, the seventh preset time period is greater than or equal to the time period required to complete 10 chromatographic analysis projects.
[0188] As an implementation manner, the seventh preset duration is greater than or equal to 5 minutes and less than or equal to 2 hours.
[0189] As an embodiment, the liquid chromatograph analyzer 100 also includes a waste liquid channel 190. In a first connection state, the reversing valve 130 connects the sample supply component 110, the test liquid preparation channel 140 and the waste liquid channel 190, and connects the liquid-phase fluid supply component 120 and the chromatographic column 150. In a second connection state, the reversing valve 130 connects the liquid-phase fluid supply component 120, the test liquid preparation channel 140 and the chromatographic column 150, and connects the sample supply component 110 and the waste liquid channel 190.
[0190] As an embodiment, the liquid-phase fluid supply assembly 120 further includes a third drive device 124. The first drive device 121 is used to drive the liquid-phase fluid to flow toward the reversing valve 130 and the chromatographic column 150. The first drive device 121 draws a first fluid from the first fluid container 20 and delivers it to the reversing valve 130 and the chromatographic column 150. The third drive device 124 draws a second fluid from the second fluid container 30 and delivers it to the reversing valve 130 and the chromatographic column 150. During the process of the liquid-phase fluid supply assembly 120 driving the test fluid in the test fluid preparation channel 140 to be delivered to the chromatographic column 150, the first drive device 121 is controlled to be in an operating state, and the third drive device 124 is controlled to be in a stopped state. The control assembly 500 is further configured to control the operation of the first driving device 121 and the second driving device 126 during elution of a test solution, and to adjust the operating parameters of the first driving device 121 and the second driving device 126 so that the liquid-phase fluid supply assembly 120 supplies at least two liquid-phase fluids containing a second fluid of different concentrations to the chromatographic column 150 at different time periods; wherein the ionic strength of the second fluid is greater than the ionic strength of the first fluid. This embodiment allows for the online configuration of liquid-phase fluids of different concentrations and achieves a gradient elution effect.
[0191] As an embodiment, the liquid-phase fluid supply assembly 120 further includes a housing assembly 180 and a mixing element 125. The mixing element 125 has a first input port, a second input port, and an output port. The energy storage device 122 is connected between the first input port and the first drive element 121 via a fluid path. The third drive element 124 is connected to the second input port. The reversing valve 130 is connected to the output port. The housing assembly 180 is formed with a first fluid reservoir and a second fluid reservoir. The first fluid reservoir is used to accommodate the first fluid container 20, and the second fluid reservoir is used to accommodate the second fluid container 30. The first drive element 121 is used to draw the first fluid from the first fluid container 20 and push it to the reversing valve 130. The third drive element 124 is used to draw the second fluid from the second fluid container 30 and push it to the reversing valve 130. In this embodiment, by adjusting the mixing ratio of the first and second fluids, eluents containing different concentrations of the second fluid can be produced. This enables the online preparation of eluents of varying concentrations, meets the requirements of different eluent concentrations, and helps reduce material volume and material costs.
[0192] As an embodiment, the first fluid may be liquid A, and the second fluid may be liquid B.
[0193] Of course, in specific applications, the liquid-phase fluid supply assembly 120 is not limited to employing the aforementioned gradient elution scheme. For example, as an alternative embodiment, the liquid-phase fluid supply assembly 120 may also employ an isocratic elution scheme. In this alternative embodiment, the liquid-phase fluid supply assembly 120 further includes a switching member, wherein the input end of the first driving device 121 is switchably connected to a third fluid container containing a third fluid and a fourth fluid container containing a fourth fluid via the switching member. The first driving device 121 is configured to drive the liquid-phase fluid toward the reversing valve 130 and the chromatographic column 150, including: when the switching member connects the first driving device 121 to the third fluid container, the first driving device 121 draws the third fluid from the third fluid container and discharges it to the reversing valve 130 and the chromatographic column 150; when the switching member connects the first driving device 121 to the fourth fluid container, the first driving device 121 draws the fourth fluid from the fourth fluid container and discharges it to the reversing valve 130 and the chromatographic column 150. The third fluid and the fourth fluid are two liquid-phase fluids containing different concentrations of the second fluid. During the process of the liquid-phase fluid supply assembly 120 driving the test solution in the test solution preparation channel 140 to be delivered to the chromatographic column 150, the switching member connects the state of the first driving device 121 and the third fluid container, and controls the first driving device 121 to be in an activated and running state. The control assembly 500 is further configured to: during the process of eluting a test solution, in the first elution phase, control the switching member to connect the state of the first driving device 121 and the third fluid container, and control the first driving device 121 to draw the third fluid from the third fluid container and discharge it to the reversing valve 130 and the chromatographic column 150; in the second elution phase, control the switching member to connect the state of the first driving device 121 and the fourth fluid container, and control the first driving device 121 to draw the fourth fluid from the fourth fluid container and discharge it to the reversing valve 130 and the chromatographic column 150, so that the liquid-phase fluid supply assembly 120 supplies at least two liquid-phase fluids containing different concentrations of the second fluid to the chromatographic column 150 at different time periods.
[0194] As an embodiment, the sample supply assembly 110 includes a sampling component 111, a first reaction container 112, and a sample infusion liquid circuit 113. The sampling component 111 is used to draw the sample from the sample container and distribute it to the first reaction container 112. The sample infusion liquid circuit 113 is used to draw the hemolytic agent from the hemolytic agent container 40 and distribute it to the first reaction container 112, and is used to transport the test solution made of at least the sample and the hemolytic agent in the first reaction container 112 to the test solution preparation channel 140 through the reversing valve 130. The sample infusion liquid circuit 113 is provided with a suction and discharge power component 1231. In this embodiment, the hemolytic agent is distributed to the first reaction container 112 by the sample infusion liquid circuit 113, so that the sample infusion liquid circuit 113 can be reused, and there is no need to set up an additional pipette needle to distribute the hemolytic agent. The hemolytic agent mainly dissolves the red blood cells to release hemoglobin in the red blood cells in the sample, so that the whole blood sample can be processed into a test solution. Of course, in specific applications, the hemolytic agent can also be replaced with deionized water, purified water, or distilled water, which swells and ruptures the red blood cells in the sample through osmotic pressure. Deionized water, purified water, or distilled water primarily swells and ruptures the red blood cells in the whole blood sample through osmotic pressure, causing the red blood cells in the sample to release hemoglobin, thereby processing the whole blood sample into a test solution.

[0201] As an embodiment, the blood cell analyzer 200 performs white blood cell differential counting and reticulocyte counting tests on the optical detection test fluid (at least made of a sample) flowing through the detection area of the flow chamber under the influence of the sheath fluid through the optical detection component.
[0202] As an embodiment, the blood cell analyzer 200 performs red blood cell detection and platelet detection on the impedance detection test fluid (at least made of a sample) through the impedance detection component.
[0203] As an embodiment, the control component 500 includes a first controller provided in the liquid chromatography device and a second controller provided in the blood cell analyzer 200 .
[0204] The present embodiment further provides a liquid chromatography device, comprising a sample supply assembly 110, a liquid-phase fluid supply assembly 120, a reversing valve 130, a test solution preparation channel 140, a chromatographic column 150, a detector 160, and a first controller.

The reversing valve 130 has a switchable first connection state and a second connection state: in the first connection state, the reversing valve 130 connects the sample supply assembly 110 and the test solution preparation channel 140 and connects the liquid-phase fluid supply assembly 120110 and the chromatographic column 150; in the second connection state, the reversing valve 130 connects the liquid-phase fluid supply assembly 120110, the test solution preparation channel 140, and the chromatographic column 150; the sample supply assembly 110 is used to supply the sample to the test solution preparation channel 140 via the reversing valve 130. The test liquid is made of a sample; the liquid-phase fluid supply component 120110 is used to drive the test liquid in the test liquid preparation channel 140 to be transported to the chromatographic column 150 through the liquid-phase fluid, and to drive the liquid-phase fluid to flow through the reversing valve 130 and the chromatographic column 150 in sequence; the chromatographic column 150 is used to adsorb the test liquid, and to supply the liquid-phase fluid to elute the test liquid to form a test liquid; the detector 160 is used to analyze the test liquid flowing out of the chromatographic column 150; the liquid-phase fluid supply component 120110 includes a first drive device 121 and an energy storage device 122, the first drive device 121 is used to drive the liquid-phase fluid to flow toward the reversing valve 130 and the chromatographic column 150, the energy storage device 122 is arranged between the first drive device 121 and the reversing valve 130, and the energy storage device 122 is used to store potential energy or release the stored potential energy. The first controller is configured to: during the execution of a chromatographic analysis project for a sample, control the first driving device 121 to drive the liquid phase fluid to flow so as to elute the test solution adsorbed on the chromatographic column 150, and control the energy storage device 122 to store potential energy through the pressure of the liquid phase fluid; after completing the chromatographic analysis project for a sample and when executing the chromatographic analysis project for the next sample, control the energy storage device 122 to release the potential energy stored during the execution of the chromatographic analysis project for a sample to assist in driving the liquid phase fluid to flow toward the reversing valve 130 and the chromatographic column 150.
[0205] As an embodiment, the liquid-phase fluid supply assembly 120 further includes a locking and releasing device 123, which is used to lock and release the energy storage device 122. The locking and releasing device 123 can switch between a locked state and a released state. In a specific application, when the locking and releasing device 123 is in the released state, the energy storage device 122 can store potential energy under the pressure of the liquid-phase fluid; when the locking and releasing device 123 is in the locked state, the energy storage device 122 is locked and the potential energy stored in the energy storage device 122 cannot be released; when the locking and releasing device 123 switches from the locked state to the released state, the potential energy stored in the energy storage device 122 can be released. In this embodiment, an energy storage device 122 and a locking and releasing device 123 are provided in the liquid-phase fluid supply component 120, and the locking and releasing device 123 is provided to release the potential energy storage and release component 1222 of the energy storage device 122 in the released state to allow the energy storage device 122 to store and release potential energy under the pressure of the liquid-phase fluid, and the locking and releasing device 123 is provided to lock the potential energy storage and release component 1222 in the locked state to prevent the energy storage device 122 from releasing the stored potential energy, so that the liquid-phase fluid supply component 120 has the function of storing and releasing potential energy in addition to providing liquid-phase fluid of a certain pressure.
[0206] As an embodiment, the energy storage device 122 includes a shell 1221 and a potential energy storage and release component 1222. The potential energy storage and release component 1222 is at least partially disposed in the shell 1221 and is separated in the shell 1221 to form a liquid cavity 1223 for liquid phase fluid to flow through. The potential energy storage and release component 1222 is at least partially capable of moving relative to the shell 1221 to change the size of the liquid cavity 1223 and store potential energy or release the stored potential energy.
[0207] In one embodiment, the locking and releasing device 123 can switch between a locked state and a released state: in the locked state, the locking and releasing device 123 applies a force to the potential energy storage and release component 1222 to lock the potential energy storage and release component 1222, thereby preventing the potential energy storage and release component 1222 from moving relative to the housing 1221 and releasing the stored potential energy. In the released state, the potential energy storage and release component 1222 can move relative to the housing 1221 under the pressure of the liquid fluid to store potential energy. When the locking and releasing device 123 removes the force applied to the potential energy storage and release component 1222, the potential energy storage and release component 1222 is released, thereby allowing the potential energy storage and release component 1222 to move relative to the housing 1221 and release the stored potential energy. In this embodiment, the locking and releasing device 123 locks the potential energy storage and release component 1222 by directly applying a force to the potential energy storage and release component 1222.
[0208] As an embodiment, the above-mentioned control of the energy storage device 122 to store potential energy through the pressure of the liquid-phase fluid includes: controlling the lock-release device 123 to be in a released state to allow the energy storage device 122 to store potential energy through the pressure of the liquid-phase fluid.

In this embodiment, after completing the chromatographic analysis project of a sample, the locking device 123 is switched from the released state to the locked state to prevent the energy storage device 122 from releasing the stored potential energy, thereby achieving the effect of storing energy and maintaining pressure. When executing the chromatographic analysis project of the next sample, the energy stored in the previous sample can be used to assist the liquid phase fluid in quickly building up pressure; of course, in specific applications, as an alternative implementation scheme, when two adjacent samples are continuously injected or the injection interval is very small (for example, less than the first preset time length described below), the pressure can also be maintained by controlling the first driving device 121 to keep driving the liquid phase fluid to flow, without the need for the locking device 123 to switch from the released state to the locked state, but this may result in a large consumption of the liquid phase fluid.
