Description

Technical Field

[0001] The present invention relates to a liquid supply system and a method thereof. Background Art

[0002] A sample analysis device is used to detect and analyze specific biological components, chemical substances, etc. contained in a sample. To avoid sample cross - contamination, after sampling and sample addition are completed, the dispensing needle is cleaned, and the dispensing needle can perform the next sampling and sample addition operation only after the cleaning is completed.

[0003] Taking an immunoassay device as an example - to meet the requirements such as cleaning of the sample addition needle, the immunoassay device generally is equipped with cleaning liquid for cleaning the needle pipeline. There are two sources for introducing the cleaning liquid: one is to connect to the deionized water pipeline in the laboratory, and the instrument controls whether to let water in by controlling the switching valve according to the test needs; the other is a bucket storing the cleaning liquid. When the instrument is designed, this built - in bucket is set to supply the cleaning liquid to the instrument. When the cleaning liquid in the bucket is exhausted, the instrument will give an alarm to notify the user to replace it.

[0004] Currently, there are still areas that need improvement in these cleaning liquid supply solutions. Summary of the Invention

[0096] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid overwhelming the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0097] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence unless it is stated that a certain sequence must be followed.

[0098] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0099] The sample analysis device is connected to the deionized water pipeline in the department. The advantage is that there is no need to worry about the problem of running out of cleaning liquid, but the disadvantage is that the cleaning liquid may affect the sample detection itself, because the microorganisms in the water supplied by the deionized water pipeline may interfere with the sample detection, especially for some projects with high detection sensitivity, typically immunoassay projects. Therefore, the current sample analysis device generally adopts the method of built-in cleaning liquid barrel, that is, the closed cleaning liquid barrel produced by the manufacturer is built into the device and connected to the cleaning pipeline of the instrument itself; accordingly, due to the barrel method, it is necessary to replace the new cleaning liquid barrel in time when the cleaning liquid in the barrel is exhausted, especially when the number of tests of the instrument is relatively large, it is necessary to pay attention to and replace the cleaning liquid barrel multiple times, which will consume a lot of time and energy. If the replacement is not timely, it may also cause the instrument to suspend the test and cause the instrument to be idle.

[0100] In order to increase the number of on-machine tests supported by the cleaning liquid, so that the sample analysis device can work continuously, and at the same time to reduce the number of replacement times of the built-in liquid storage barrel to improve the work efficiency of the staff, the present application provides a liquid supply system, which provides cleaning liquid to the sample analysis device through a liquid storage barrel arranged outside the sample analysis device. In clinical laboratory departments, there are usually multiple sample analysis devices. Considering economic, space and other factors, the present application provides a liquid supply system that can provide cleaning liquid to one or more sample analysis devices. In order to achieve adaptive liquid supply and reduce user interaction, the liquid supply system provided by the present application can control the external liquid supply to the sample analysis device according to the load state of the sample analysis device. The liquid supply system and method provided by the present application will be described in detail below through specific embodiments.

[0101] A liquid supply system is disclosed in some embodiments. The liquid supply system of the present application can supply one or more sample analysis devices, which is described in detail below.

[0102] In some embodiments, please refer to Figures 1 to 13 The liquid supply system may include a first liquid supply pipeline 100, a second liquid supply pipeline 200, a buffer container 40, a valve assembly, a manifold 20, a plurality of external liquid storage barrels 10 and a processor 70, wherein the first liquid supply pipeline 100, the valve assembly, the manifold 20 and the plurality of external liquid storage barrels 10 are all arranged outside the sample analysis device, which is not only convenient for replacing the external liquid storage barrel 10, but also convenient for connecting the external liquid storage barrel 10 to the cleaning component 400 of the sample analysis device through the second liquid supply pipeline 200 to ensure sufficient cleaning liquid for cleaning the dispensing needle.

[0103] Specifically, multiple external liquid storage buckets 10 are used to store cleaning liquid; a confluence block 20 is used to collect the liquids on multiple external liquid storage buckets 10 together; a valve assembly is arranged on the first liquid supply pipeline and is used to control the liquid flow between each external liquid storage bucket 10 and the confluence block 20; a buffer container 40 is used to store the cleaning liquid transferred by the confluence block 20, so that the sample analysis device can extract the cleaning liquid from the buffer container 40 to clean the dispensing needle; a second liquid supply pipeline 200 is connected between the confluence block 20 and the buffer container 40, and a pressure source 50 and a detection unit 60 are arranged on the second liquid supply pipeline 200.

[0104] Among them, the pressure source 50 is arranged between the detection unit 60 and the buffer container 40. The pressure source 50 is used to generate the pressure for the external liquid storage bucket 10 to drain liquid into the buffer container 40. The detection unit 60 is used to detect the liquid condition on each external liquid storage bucket 10, so that when the external liquid storage bucket 10 drains liquid into the buffer container 40, the valve assembly can be switched according to the liquid condition on each external liquid storage bucket 10.

[0105] It should be noted that the dispensing needle includes a sample needle, a reagent needle, a cleaning needle, etc. on the sample analysis device. After the sample needle, the reagent needle, and the cleaning needle complete actions such as sampling or adding samples, cleaning treatment needs to be carried out to prepare for the next sampling or adding samples, etc., to avoid cross-contamination.

[0106] After adopting the above technical solution, when the dispensing needle on the sample analysis device needs to be cleaned, the second liquid supply pipeline 200 transfers the liquid inside the buffer container 40 to the cleaning assembly 400 on the sample analysis device for cleaning the dispensing needle. Among them, the liquid on the buffer container 40 is transferred from the external liquid storage bucket 10 through the confluence block 20 and then through the second liquid supply pipeline 200. The valve assembly is arranged between the confluence block 20 and the external liquid storage bucket 10. In this way, the processor 70 can select the external liquid storage bucket 10 by controlling the closing or opening of the valve assembly for the replacement of the external liquid storage bucket 10. At the same time, it can also prevent the pressure source 50 from continuously extracting cleaning liquid from the external liquid storage bucket 10 with the cleaning liquid used up, resulting in an increase in the air in the buffer container 40 and even causing a large amount of resource waste.

[0107] Therefore, the above-mentioned detection unit 60 is connected between the pressure source 50 and the manifold block 20 to judge the liquid conditions on each external liquid storage barrel 10. If the detection unit 60 detects that there is still a large amount of cleaning liquid on the external liquid storage barrel 10 being pumped by the current pressure source 50, the processor 70 controls the first liquid supply pipeline 100 to communicate between the external liquid storage barrel 10 being pumped by the current pressure source 50 and the manifold block 20 through the valve assembly; if the detection unit 60 detects that the cleaning liquid on the external liquid storage barrel 10 being pumped by the current pressure source 50 has been consumed, the processor 70 cuts off the communication between the first liquid supply pipeline 100, the external liquid storage barrel 10 being pumped by the current pressure source 50 and the manifold block 20 through the valve assembly, and opens the communication between the first liquid supply pipeline 100, another external liquid storage barrel 10 and the manifold block 20, so that the external liquid storage barrel 10 can continuously converge the cleaning liquid to the manifold block 20 and then transfer it to the buffer container 40 through the second liquid supply pipeline 200.

[0108] In addition, the buffer container 40 can be arranged outside the sample analysis device or inside the sample analysis device, and its purpose is to provide cleaning liquid for the cleaning component 400 on the sample analysis device to ensure that the sample analysis device can work continuously.

[0109] In an alternative embodiment, the valve assembly includes a plurality of control valves 30. The number of the control valves 30 matches the number of the external liquid storage barrels 10, and each control valve 30 is correspondingly arranged on the first liquid supply pipeline 100. In this embodiment, the plurality of control valves 30 are all electrically connected to the processor 70, so that the processor 70 can control the opening or closing of the control valves 30 installed on the first liquid supply pipeline 100 according to the detection result of the detection unit 60, that is, according to the liquid conditions on the external liquid storage barrels 10. This not only facilitates the replacement of the external liquid storage barrels 10, but also avoids the pressure source 50 from continuously pumping cleaning liquid from the external liquid storage barrel 10 with the cleaning liquid used up, resulting in a large amount of resource waste.

[0110] Specifically, each external liquid storage barrel 10 is connected to the manifold block 20 through a first liquid supply pipeline 100, and each first liquid supply pipeline 100 is provided with the above-mentioned control valve 30 to control the communication or disconnection between the external liquid storage barrel 10 and the manifold block 20. The manifold block 20 is then connected to the buffer container 40 through the second liquid supply pipeline 200. The pressure source 50 and the detection unit 60 are installed on the second liquid supply pipeline 200, which can not only reduce the number of the pressure source 50 and the detection unit 60 and lower the production cost of the liquid supply system, but also can monitor the liquid conditions on each external liquid storage barrel 10 in real time to facilitate the mutual switching between the plurality of control valves 30, and also facilitate the user to replace the external liquid storage barrel 10 with the external cleaning liquid used up.

[0111] In addition, the positions of the pressure source 50 and the detection unit 60 can be swapped with each other. In this embodiment, the detection unit 60 is mainly arranged on one side of the second liquid supply pipeline 200 close to the confluence block 20, and the pressure source 50 is arranged on one side of the second liquid supply pipeline 200 close to the buffer container 40, so as to quickly detect the liquid condition on the external liquid storage bucket 10 and stop the pressure source 50 from working, avoiding excessive air from entering the buffer container 40.

[0112] In an alternative embodiment, a liquid level detector is provided inside the buffer container 40. The liquid level detector is electrically connected to the pressure source 50. The liquid level detector can detect the liquid level height of the liquid on the buffer container 40, so that the processor 70 can control the opening or closing of the pressure source 50 through the liquid level detector.

[0113] Generally, the liquid level detector can adopt an ordinary pressure sensor to detect the liquid level height of the cleaning liquid in the buffer container 40. When the liquid level detector detects that the liquid level height of the cleaning liquid in the buffer container 40 is lower or higher than the preset value, the processor 70 sends a signal to remind the user or control the pressure source 50 to work or stop working. By adopting the liquid level detector, the cleaning liquid in the buffer container 40 can be detected in real time. When the cleaning liquid in the buffer container 40 is insufficient, the cleaning liquid on the external liquid storage bucket 10 can be continuously loaded into the buffer container 40, avoiding the inability of the sample analysis device to work continuously due to the insufficient cleaning liquid in the buffer container 40.

[0114] In an alternative embodiment, the liquid level detector includes a first liquid inlet detector 411 and a first liquid stop detector 412. Both the first liquid inlet detector 411 and the first liquid stop detector 412 are installed inside the buffer container 40. When the liquid on the buffer container 40 touches the position of the first liquid inlet detector 411, the processor 70 controls the pressure source 50 to work and controls the external liquid storage bucket 10 to drain liquid into the buffer container 40. When the liquid on the buffer container 40 touches the position of the first liquid stop detector 412, the processor 70 controls the pressure source 50 to stop working and pauses the external liquid storage bucket 10 from draining liquid into the buffer container 40.

[0115] In an alternative embodiment, the liquid level detector further includes a second liquid inlet detector 413 and a second liquid stop detector 414. Among them, the second liquid inlet detector 413 is arranged below the first liquid inlet detector 411, and the second liquid stop detector 414 is arranged above the first liquid stop detector 412. When the liquid on the buffer container 40 touches the position of the second liquid inlet detector 413, the processor 70 controls the pressure source 50 to work and controls the external liquid storage bucket 10 to drain liquid into the buffer container 40. When the liquid on the buffer container 40 touches the position of the second liquid stop detector 414, the processor 70 controls the pressure source 50 to stop working and pauses the external liquid storage bucket 10 from draining liquid into the buffer container 40.

[0116] Specifically, the liquid level detector is a four-section float switch. The four-section float switches are all arranged in the buffer container 40, and the four sections of floats are used to detect the relationship between the liquid level height of the cleaning liquid in the buffer container 40 and four heights, which are H1, H2, H3, and H4 respectively. In this embodiment, the H1 height is set at the bottom of the buffer container 40 or slightly above the bottom, the H4 height is set at the top of the buffer container 40 or slightly below the top, the H2 height and the H3 height are set in the middle of the buffer container 40, and the H2 height is located slightly above the H1 height, and the H3 height is located slightly below the H4 height, that is, H1 < H2 < H3 < H4.

[0117] Among them, the second liquid inlet detector 413 corresponds to the H1 height, the second liquid stop detector 414 corresponds to the H4 height, the first liquid inlet detector 411 corresponds to the H2 height, the first liquid stop detector 412 corresponds to the H3 height. The second liquid inlet detector 413 is mainly to prevent the cleaning liquid in the buffer container 40 from being insufficient due to the damage of the first liquid inlet detector 411, and the second liquid stop detector 414 is mainly to prevent the cleaning liquid in the buffer container 40 from overflowing due to the damage of the first liquid stop detector 412.

[0118] In an alternative embodiment, as Figures 1 to 5 shown, the buffer container 40 includes a first buffer container 41. Among them, the first buffer container 41 is arranged inside the sample analysis device. The second liquid supply pipeline 200 is used to connect the first buffer container 41 and the manifold 20 outside the sample analysis device to transfer the liquid on the manifold 20 into the first buffer container 41. Generally, each sample analysis device will basically be provided with a first buffer container 41 inside itself. In this way, the external storage bucket 10 converging on the manifold 20 can be connected to the first buffer container 41 through the second liquid supply pipeline 200, which not only does not require adding an additional buffer container 40 externally, but also does not require a large-scale modification of the program inside the sample analysis device, saving a lot of manpower and material resources.

[0119] In an alternative embodiment, as Figure 5 shown, the pressure source 50 and the detection unit 60 are arranged outside the sample analysis device. Inside the sample analysis device, there is a third liquid supply pipeline 300 for switching with the second liquid supply pipeline 200, and an internal liquid supply assembly is connected to the third liquid supply pipeline 300.

[0120] Among them, the internal liquid supply assembly includes an internal control valve 31, an internal detection unit 61, an internal pressure source 51, and at least one internal storage bucket 11. The internal control valve 31 is arranged between the internal detection unit 61 and the internal storage bucket 11, and the internal pressure source 51 is arranged between the first buffer container 41 and the internal detection unit 61.

[0121] In this embodiment, the number of the internal liquid storage barrels 11 and the internal control valves 31 is two each. The two internal control valves 31 are correspondingly installed between the two internal liquid storage barrels 11 and the internal manifold block 21. The internal detection unit 61 and the internal pressure source 51 are arranged between the internal manifold block 21 and the first buffer container 41. That is to say, the liquid supply fittings of the internal liquid supply system of the sample analysis device are substantially the same as those of the external liquid supply system of the sample analysis device. When the cleaning liquid in the internal liquid storage barrel 11 is used up, the third liquid supply pipeline 300 on the first buffer container 41 is directly replaced with the second liquid supply pipeline 200, so that the cleaning liquid on the external liquid storage barrel 10 can be discharged into the first buffer container 41, ensuring that the sample analysis device has enough cleaning liquid to clean the dispensing needle, so that it can work continuously.

[0122] In an alternative embodiment, as Figures 1 to 4 shown, the pressure source 50 and the detection unit 60 are arranged inside the sample analysis device to reduce the manufacturing cost of the external liquid supply system. That is, after the external liquid storage barrel 10 converges to the manifold block 20, it can be directly connected to the pressure source 50 and the detection unit 60 inside the sample analysis device through the second liquid supply pipeline 200. In this way, the detection unit 60 can be used to detect the liquid condition of the external liquid storage barrel 10, and at the same time, the cleaning liquid on the external liquid storage barrel 10 can be discharged into the first buffer container 41 through the pressure source 50.

[0123] Generally, the inside of the sample analysis device is usually configured with a buffer container 40, a pressure source 50, a detection unit 60, an internal control valve 31 and two internal liquid storage barrels 11. The cleaning liquid on the two internal liquid storage barrels 11 converges to the internal manifold block 21 and then is discharged into the buffer container 40. The internal control valve 31 is used to control the closing and opening of the two internal liquid storage barrels 11, so that the internal liquid storage barrels 11 can supply liquid to the buffer container 40 through the pressure source 50. Among them, the internal control valve 31 is arranged between the internal manifold block 21 and the internal liquid storage barrel 11, and the detection unit 60 is arranged between the pressure source 50 and the internal manifold block 21.

[0124] In an alternative embodiment, as Figure 1 shown, a third liquid supply pipeline 300 is connected between the manifold block 20 and the detection unit 60, and an internal liquid supply component is connected to the third liquid supply pipeline 300. In this embodiment, the internal liquid supply component is composed of an internal control valve 31 and at least one internal liquid storage barrel 11. When the cleaning liquid in the internal liquid storage barrel 11 is used up, the internal control valve 31 closes all the third liquid supply pipelines 300 connected to the internal liquid storage barrel 11, and the control valve 30 outside the sample analysis device is opened, so that the pressure source 50 can transfer the cleaning liquid on the external liquid storage barrel 10 to the first buffer container 41, so as to ensure that the sample analysis device can work continuously.

[0125] In an alternative embodiment, as Figure 2 shown, the manifold block 20 can be positioned at one of the internal liquid storage barrels 11 inside the sample analysis device through the second liquid supply pipeline 200, so that the pipeline inside the sample analysis device does not need to be modified, ensuring the integrity of the pipeline inside the sample analysis device.

[0126] In an alternative embodiment, as Figure 3 and Figure 4 shown, the buffer container 40 further includes a second buffer container 42 disposed outside the sample analysis device. An external pressure source 52 and an external detection unit 62 are provided on the second liquid supply pipeline between the second buffer container 42 and the manifold block 20. In this embodiment, the external pressure source 52 is disposed between the external detection unit 62 and the second buffer container 42, and the detection unit 60 is disposed between the pressure source 50 and the second buffer container 42. Since the external pressure source 52, the external detection unit 62, and the second buffer container 42 are all disposed outside the sample analysis device, therefore, connecting the second buffer container 42 to the pipeline inside the sample analysis device can avoid modifying the pipeline inside the sample analysis device and even changing the control program of the pipeline inside the sample analysis device, thereby ensuring the integrity of the pipeline and the control program inside the sample analysis device and saving a large amount of manpower and material resources.

[0127] Specifically, the external pressure source 52 is mainly used to transfer the cleaning liquid on the external liquid storage barrel 10 to the second buffer container 42, and the external detection unit 62 is used to detect the liquid condition of the cleaning liquid in each external liquid storage barrel 10, so that the control valve 30 can control the opening or closing of the first liquid supply pipeline 100 connected to each external liquid storage barrel 10; the pressure source 50 is mainly used to transfer the cleaning liquid on the second buffer container 42 to the first buffer container 41 to ensure the continuous operation of the sample analysis device; the detection unit 60 is mainly used to detect the liquid condition of the cleaning liquid on the second buffer container 42.

[0128] In addition, as Figure 4 shown, the second buffer container 42 can also be positioned at one of the internal liquid storage barrels 11 inside the sample analysis device through the second liquid supply pipeline 200, so that the pipeline inside the sample analysis device does not need to be modified, ensuring the integrity of the pipeline inside the sample analysis device.

[0129] In an alternative embodiment, as Figure 6 shown, the second buffer container 42 is provided with a communication interface 421 for communicating with the communication interface on another second buffer container 42.

[0130] Specifically, as Figure 6As shown, there can be multiple second buffer containers 42 outside the sample analysis device. Each second buffer container 42 can be interconnected through a communication interface 421 so as to continuously supply liquid to the first buffer container 41 inside the sample analysis device, ensuring that the sample analysis device can work continuously. Of course, only one second buffer container 42 can also be configured outside each sample analysis device, and the second buffer containers 42 can be interconnected through the communication interface 421 so that the cleaning liquid on the second buffer containers 42 can be borrowed from each other among multiple sample analysis devices. Among them, an external pressure source 52 transfers the cleaning liquid on multiple external liquid storage barrels 10 to the second buffer container 42, and the second buffer container 42 then transfers the cleaning liquid to the first buffer container 41 inside one or more sample analysis devices respectively, so that the cleaning component on the sample analysis device can extract the cleaning liquid from the first buffer container 41 to clean the dispensing needle, thereby ensuring that the sample analysis device can work continuously.

[0131] After adopting the above technical solution, since the second buffer container 42 is provided with multiple communication interfaces, when a sample analysis device can borrow the second buffer container 42 outside other sample analysis devices at the same time. For example, if the currently working device is a biochemical analyzer and there is only one second buffer container 42 outside the biochemical analyzer for liquid supply, but the biochemical analyzer needs more cleaning liquid to complete the current test. At this time, the biochemical analyzer can borrow one or more of the second buffer containers 42 externally configured on the hematology analyzer, special protein analyzer, glycosylated hemoglobin analyzer, immunoassay analyzer, and blood type analyzer to implement the principle of resource sharing, and can also ensure that the biochemical analyzer has enough cleaning liquid to clean the dispensing needle on the biochemical analyzer.

[0132] Of course, the second buffer container 42 can be supplied with liquid through two external liquid storage barrels 10 or six external liquid storage barrels 10. Generally, the number of external liquid storage barrels 10 configured with the second buffer container 42 is fixed, for example, there are only six. And at this time, the biochemical analyzer requires the usage amount of eight external liquid storage barrels 10. Therefore, two second buffer containers 42 can be interconnected so that after the biochemical analyzer uses up the cleaning liquid on one of the second buffer containers 42, it can then use the cleaning liquid on the other second buffer container 42 to ensure that the biochemical analyzer can work continuously. In an alternative embodiment, as Figure 8 and Figure 9As shown, since the structure of the sample analysis device is becoming more and more compact and its functions are becoming more and more complete, the space inside the sample analysis device that can accommodate the buffer container 40, the pressure source 50, and the detection unit 60 has relatively decreased. In this embodiment, the buffer container 40, the pressure source 50, and the detection unit 60 are all arranged outside the sample analysis device, so as to further alleviate the problem of the compact internal space of the sample analysis device. In addition, the buffer container 40 is provided with a communication interface 421 for communicating with the communication interface 421 on another buffer container 40, so that the sample analysis device can extract the cleaning liquid from more interconnected buffer containers 40.

[0133] In an alternative embodiment, as Figure 10 shown, the second buffer container 42 is provided with a plurality of liquid supply interfaces 422, and the plurality of liquid supply interfaces 422 are respectively connected to the cleaning components 400 on a plurality of sample analysis devices, that is, the second buffer container 42 can supply liquid to multiple sample analysis devices through the liquid supply interfaces 422.

[0134] Specifically, after the external pressure source 52 transfers the cleaning liquid on the plurality of external liquid storage barrels 10 to the second buffer container 42, the second buffer container 42 then transfers the cleaning liquid to the first buffer containers 41 inside multiple sample analysis devices respectively, so that the cleaning components on the sample analysis devices can extract the cleaning liquid from the first buffer containers 41 to clean the dispensing needles, thereby ensuring that the sample analysis devices can work continuously.

[0135] After adopting the above technical solution, since the second buffer container 42 is provided with a plurality of liquid supply interfaces 422, the second buffer container 42 can supply liquid to multiple sample analysis devices simultaneously. Especially when the laboratory control is insufficient, for example, there are sample analysis devices such as biochemical analyzers, hematology analyzers, special protein analyzers, glycosylated hemoglobin analyzers, immunoassays, and blood group analyzers placed in the laboratory, and when the internal cleaning liquid of two of these sample analysis devices is insufficient, therefore, these two sample analysis devices can be simultaneously connected to the liquid supply interfaces 422 of the second buffer container 42 so that the two sample analysis devices can work continuously. In an alternative embodiment, as Figure 11 shown, since the structure of the sample analysis device is becoming more and more compact and its functions are becoming more and more complete, the space inside the sample analysis device that can accommodate the buffer container 40, the pressure source 50, and the detection unit 60 has relatively decreased. In this embodiment, the buffer container 40, the pressure source 50, and the detection unit 60 are all arranged outside the sample analysis device, so as to further alleviate the problem of the compact internal space of the sample analysis device. In addition, the buffer container 40 is provided with a plurality of liquid supply interfaces so that the cleaning components on multiple sample analysis devices can extract the cleaning liquid from the buffer container 40 through the corresponding liquid supply interfaces.

[0136] In an alternative embodiment, as Figures 1 to 11 shown, the detection unit 60 includes a bubble detector, which is disposed on the second liquid supply line 200 and is configured to obtain bubble information on the second liquid supply line 200, so that the control valve 30 can determine whether the cleaning liquid in the external liquid storage tank 10 or the internal liquid storage tank 11 has been consumed based on the obtained bubble information, and then perform corresponding switching to ensure that the external liquid storage tank 10 or the internal liquid storage tank 11 can continuously supply liquid to the buffer container 40.

[0137] It should be noted that the connection between the second liquid supply line 200 and the sample analysis device is achieved through quick connectors, which can quickly combine the liquid supply components outside the sample analysis device with the liquid supply components inside the sample analysis device. This not only makes the connection more stable but also facilitates the disassembly and assembly of the pipelines, thereby saving a large amount of manpower and material resources.

[0138] As Figures 6 to 7 shown, a liquid supply system in an embodiment includes a plurality of sample analysis devices and an external liquid supply component. Among them, the external liquid supply component includes a plurality of external liquid storage tanks 10, a manifold block 20, a first liquid supply line 100, a valve assembly, a buffer container 42, and a second liquid supply line 200. In this embodiment, the plurality of external liquid storage tanks 10, the manifold block 20, the first liquid supply line 100, the valve assembly, and the buffer container 42 are all disposed outside the sample analysis device, and the second liquid supply line 200 is connected between the manifold block 20 and the buffer container 42.

[0139] Specifically, the plurality of external liquid storage tanks 10 are used to store the cleaning liquid; the manifold block 20 is used to collect the liquids on the plurality of external liquid storage tanks 10 together; the first liquid supply line 100 is connected between the external liquid storage tank 10 and the manifold block 20 and is configured to transport the liquid on each external liquid storage tank 10 into the manifold block 20; the buffer container 42 is used to store the cleaning liquid transferred from the manifold block 20 so that the sample analysis device can extract the cleaning liquid from the buffer container 42 for cleaning the dispensing needle; the second liquid supply line 200 is provided with an external pressure source 52 and an external detection unit 62. The external pressure source 52 is disposed between the external detection unit 62 and the buffer container 40. The external pressure source 52 is used to generate the pressure for the external liquid storage tank 10 to discharge liquid to the buffer container 42, and the external detection unit 62 is used to detect the liquid conditions on each external liquid storage tank 10 so that when the external liquid storage tank 10 discharges liquid to the buffer container 42, the valve assembly can perform switching according to the liquid conditions on each external liquid storage tank 10.

[0140] In this embodiment, communication interfaces 421 are provided on the buffer container 42 for communicating with the buffer containers on another external liquid supply component, so that multiple sample analysis devices can borrow each other's buffer containers 42 for liquid supply.

[0141] As Figure 9 shown, a liquid supply system of an embodiment includes an external liquid supply component and multiple sample analysis devices; wherein, the external liquid supply component includes multiple external liquid storage barrels 10, a confluence block 20, a first liquid supply pipeline 100, a valve assembly, a buffer container 42, and a second liquid supply pipeline 200. In this embodiment, the multiple external liquid storage barrels 10, the confluence block 20, the first liquid supply pipeline 100, the valve assembly, and the buffer container 42 are all arranged outside the sample analysis device, and the second liquid supply pipeline 200 is connected between the confluence block 20 and the buffer container 42.

[0142] Specifically, the multiple external liquid storage barrels 10 are used to store cleaning liquid; the confluence block 20 is used to collect the liquids on the multiple external liquid storage barrels 10 together; the first liquid supply pipeline 100 is connected between the external liquid storage barrel 10 and the confluence block 20 for transporting the liquid on each external liquid storage barrel 10 into the confluence block 20; the buffer container 42 is used to store the cleaning liquid transferred by the confluence block 20 so that the sample analysis device can extract the cleaning liquid from the buffer container 42 for cleaning the dispensing needle; an external pressure source 52 and an external detection unit 62 are provided on the second liquid supply pipeline 200. The external pressure source 52 is arranged between the external detection unit 62 and the buffer container 40. The external pressure source 52 is used to generate the pressure for the external liquid storage barrel 10 to drain liquid into the buffer container 42, and the external detection unit 62 is used to detect the liquid condition on each external liquid storage barrel 10 so that when the external liquid storage barrel 10 drains liquid into the buffer container 42, the valve assembly can be switched according to the liquid condition on each external liquid storage barrel 10.

[0143] In this embodiment, multiple liquid supply interfaces 422 are provided on the buffer container 42, and the multiple liquid supply interfaces 422 are respectively connected to the cleaning components 400 on the multiple sample analysis devices, so that the cleaning components 400 on the multiple sample analysis devices can supply liquid through one buffer container 42.

[0144] Please refer to Figure 12, is a schematic diagram of a liquid supply system for supplying two sample analysis devices. In some embodiments, the liquid supply structure inside any one of the sample analysis devices is as follows: one or more internal liquid storage barrels 11, two internal liquid storage barrels 11 are shown in the figure. An internal control valve 31 is provided on the connecting pipeline between the internal liquid storage barrel 11 and the three-way pipe. An internal detection unit 61 and an internal pressure source 51 are provided on the connecting pipeline between the three-way pipe and the first buffer container 41. A plurality of external liquid storage barrels 10 share a second buffer container 42. An external detection unit 62 and an external pressure source 52 are provided between the second buffer container 42 and the manifold block 20. In order to enable external liquid supply, the second buffer container 42 is connected to each first buffer container 41, that is, the second buffer container 42 can supply liquid to each first buffer container 41. An external control valve 30 or an internal control valve 31 can also be provided on the pipeline connecting the second buffer container 42 and each first buffer container 41. Specifically, when external liquid supply is required, the processor 70 can select one of the external liquid storage barrels 10 for liquid supply, that is, open the external control valve 30 connected to the external liquid storage barrel 10, and the external pressure source 52 works, so that the external liquid storage barrel 10 supplies liquid to the second buffer container 42, and the sample analysis device can obtain the cleaning liquid from the second buffer container 42. Specifically, the internal control valve 31 between the second buffer container 42 and the first buffer container 41 of the sample analysis device that needs to be supplied with liquid can be opened, so that the second buffer container 42 supplies liquid to the first buffer container 41 of the corresponding sample analysis device, and the cleaning component 400 of the corresponding sample analysis device can obtain the cleaning liquid from its corresponding first buffer container 41. It should be noted that during this external liquid supply process, the internal control valve 31 connected to each internal liquid storage barrel 11 is closed. When the sample analysis device needs to perform internal liquid supply, the internal control valve 31 connected to the internal liquid storage barrel 11 that is currently supplying liquid is opened, and the internal pressure source 51 works, so that the internal liquid storage barrel 11 supplies liquid to the first buffer container 42. When the first buffer container 42 stores the cleaning liquid, the cleaning component 400 of the sample analysis device can obtain the cleaning liquid from the first buffer container 42. Compared with Figure 12 the liquid supply system disclosed Figure 13 in the liquid supply system disclosed in, in addition to being able to connect the internal liquid storage barrel 11 in the sample analysis device itself to its cleaning component 400, and being able to connect the external liquid storage barrel 10 to the cleaning component 400 of each sample analysis device, the internal liquid storage barrel 11 of one sample analysis device can also be connected to the cleaning component 400 of another sample analysis device. Through Figure 13 this structure, the internal liquid storage barrel 11 of one sample analysis device can supply liquid to another sample analysis device.

[0145] In this embodiment, the processor 70 of the liquid supply system can be used to control the external liquid supply to the sample analysis device according to the load status of each sample analysis device when the external liquid supply is enabled.

[0146] It can be understood that for different liquid supply strategies, the timing of enabling the external liquid supply will be different. If the liquid supply strategy is to preferentially use the built-in cleaning liquid, the external liquid supply is enabled when the cleaning liquid in the built-in liquid storage bucket of the sample analysis device is exhausted; if the liquid supply strategy is to preferentially use the external cleaning liquid, the external liquid supply is enabled when the liquid supply system is connected to the sample analysis device.

[0147] The liquid supply system provided in this embodiment provides the cleaning liquid through the external liquid storage bucket 10 arranged outside the sample analysis device, reduces the number of replacements of the internal liquid storage bucket 11, increases the number of in-machine tests supported by the cleaning liquid, and enables the sample analysis device to continuously perform tests for a long time; the buffer containers of the liquid supply system are respectively connected to the cleaning components on multiple sample analysis devices, and can supply external liquid to multiple sample analysis devices. When multiple sample analysis devices require external liquid supply, only one liquid supply system is needed, which can not only reduce costs but also save space; when the liquid supply system supplies external liquid to multiple sample analysis devices, it controls the external liquid supply to the sample analysis device according to the load status of each sample analysis device, realizes adaptive liquid supply, and reduces the user interaction during the liquid supply process.

[0148] The above embodiments have described the structure of the liquid supply system provided by the present application. Next, several embodiments will be used to illustrate how the liquid supply system provided by the present application realizes adaptive liquid supply according to the load status of each sample analysis device.

[0149] In one embodiment, the processor 70 controls the external liquid supply to the sample analysis device according to the load status of each sample analysis device, which may specifically include:

[0150] When some sample analysis devices are in the test state and some sample analysis devices are in the idle state, the processor 70 controls to reserve a preset number of external liquid storage barrels 10 for each sample analysis device in the idle state, and allocates the remaining external liquid storage barrels 10 to supply liquid to the sample analysis devices in the test state. By reserving a preset number of external liquid storage barrels 10 for the sample analysis devices in the idle state, it can ensure that there is sufficient cleaning liquid available for the sample analysis devices in the idle state when starting the test. Further, in order to make the reservation more reasonable, which can not only ensure that there is sufficient cleaning liquid available for the sample analysis devices in the idle state when starting the test, but also ensure the liquid supply for the sample analysis devices in the test state to the greatest extent, the processor 70 can obtain the historical liquid consumption data of each analysis device to calculate the preset number corresponding to each analysis device. The processor 70 reserves the external liquid storage barrels according to the calculated preset number corresponding to the sample analysis devices in the idle state.

[0151] When it is determined that the external liquid storage barrel 10 allocated to the sample analysis device in the test state is in the empty state, the processor controls the external liquid storage barrel 10 reserved for the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state, which can give priority to ensuring the smooth progress of the test of the sample analysis device in the test state.

[0152] The processor 70 can also set the external liquid storage barrel 10 reserved for the sample analysis device in the idle state to a releasable state or a non-releasable state. The so-called releasable state means that the external liquid storage barrel reserved for a certain sample analysis device can be used to supply liquid to other sample analysis devices in some cases, and the so-called non-releasable state means that the external liquid storage barrel reserved for a certain sample analysis device cannot be used to supply liquid to other sample analysis devices. The processor 70 can, for example, set the state of the reserved external liquid storage barrel according to the importance of the test items of the sample analysis device in the idle state or the user's input. For example, if the user determines that the sample analysis device M will definitely start testing the sample in a certain test cycle, but the time when the sample analysis device M starts the test is relatively late, and the sample analysis device M is still in the idle state when other sample analysis devices are in the test state, in order to ensure that there is sufficient cleaning liquid supply for the sample analysis device M when starting the test, the user can, for example, perform relevant operations on the state setting interface to make the processor set the external liquid storage barrel reserved for the currently idle sample analysis device M to the non-releasable state.

[0153] The processor 70 controls the external liquid storage bucket 10 reserved for the sample analysis device in the idle state. Before supplying liquid to the sample analysis device in the test state, the processor 70 also determines whether the external liquid storage bucket 10 reserved for the sample analysis device in the idle state is set to the releasable state; if so, the processor 70 controls the external liquid storage bucket 10 reserved for the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state.

[0154] Taking the external liquid supply to two sample analysis devices M1 and M2 by the liquid supply system as an example for illustration, assume that the liquid supply system has 6 external liquid storage buckets 10. When M1 is in the test state and M2 is in the idle state, if the processor 70 calculates the preset quantity of M2 as 1 based on the historical liquid consumption data of M2, the processor 70 controls to reserve 1 bucket for M2 and allocate the remaining 5 buckets to supply liquid to M1. Specifically, if the numbers of the 6 external liquid storage buckets are 1 - 6, the 6th liquid storage bucket can be reserved for the idle M2, and the 1st - 5th liquid storage buckets are allocated to supply liquid to the test - state M1. When the 1st - 5th external liquid storage buckets 10 allocated to M1 are all exhausted and in the empty state, if M2 is still in the idle state and the 6th liquid storage bucket reserved for M2 is set to the releasable state, the processor 70 controls the 6th external liquid storage bucket reserved for M2 to supply liquid to the test - state M1, giving priority to ensuring the smooth progress of the currently executing test project.

[0155] In one embodiment, the processor 70 controls the external liquid supply to the sample analysis device according to the load status of each sample analysis device, which may specifically include: each sample analysis device is pre - set with a corresponding external liquid storage bucket 10; the processor 70 controls the corresponding external liquid storage bucket to supply liquid to the corresponding sample analysis device in the test state. Among them, the processor 70 can set the corresponding external liquid storage bucket for each sample analysis device according to the historical liquid consumption data of each sample analysis device.

[0156] When the external liquid storage bucket 10 corresponding to the sample analysis device in the test state is in the empty state, the processor 70 controls the external liquid storage bucket corresponding to the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state, giving priority to ensuring the smooth progress of the currently executing test project.

[0157] In an alternative embodiment, before the processor 70 controls the external liquid storage bucket corresponding to the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state, the processor 70 also determines whether the external liquid storage bucket 10 corresponding to the sample analysis device in the idle state is set to the releasable state; if so, the processor 70 controls the external liquid storage bucket 10 corresponding to the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state.

[0158] Taking the example of an external liquid supply system supplying liquid to two sample analysis devices M1 and M2, it is assumed that the liquid supply system has 6 external liquid storage barrels numbered 1-6. The processor 70 sets barrels 1-4 as the external liquid storage barrels 10 corresponding to the sample analysis device M1 and barrels 5-6 as the external liquid storage barrels 10 corresponding to the sample analysis device M2 according to the historical liquid consumption data of M1 and M2. When M1 is in the test state and M2 is in the idle state, the processor controls the external liquid storage barrels 1-4 of 10 to supply liquid to the corresponding sample analysis device M1 in the test state. As the test progresses, when the external liquid storage barrels 1-4 of 10 corresponding to the sample analysis device M1 in the test state are in the empty state, the sample analysis device M2 is still in the idle state and its corresponding barrels 5 and 6 are set to the releasable state, then the processor controls the external liquid storage barrel 10 of No. 5 or No. 6 corresponding to the sample analysis device M2 in the idle state to supply liquid to the sample analysis device M1 in the test state.

[0159] In one embodiment, the processor 70 controls the external liquid supply to the sample analysis device according to the load status of each sample analysis device, which may specifically include: when it is determined that the remaining liquid volume of multiple external liquid storage barrels 10 is not sufficient to support the current sample analysis devices in the test state, the processor 70 supplies liquid to each sample analysis device in the test state according to the priority of the sample analysis device, realizing adaptive liquid supply in units of sample analysis devices. In this embodiment, the processor 70 may determine the priority of the sample analysis device according to the sample priority and / or project priority. The processor 70 supplies liquid to each sample analysis device in the test state according to the priority of the sample analysis device, which may specifically include: the processor 70 controls the external liquid storage barrel to supply liquid to the sample analysis device with a higher priority first, so as to ensure the normal operation of the sample analysis device with a higher priority first when the cleaning liquid is in short supply.

[0160] In an optional implementation manner, the processor 70 determines the priority of the sample analysis device according to the sample priority, which may specifically include: the more samples with a high sample priority in the sample analysis device, the higher the priority of the sample analysis device.

[0161] In clinical tests, in order to distinguish the priority levels of different samples, the sample priority can be set for identification. For example, the sample priority can be divided into three levels: high, medium, and low according to the type of the sample. Specifically, the sample priority of emergency patient samples can be set to high, the sample priority of ordinary patient samples can be set to medium, and the sample priority of physical examination samples can be set to low. Usually, the higher the sample priority, the shorter the required sample turnover time.

[0162] For example, the liquid supply system is connected to a total of five sample analysis devices, namely T1, T2, T3, T4, and T5. Currently, 3 sample analysis devices are in the test state, which are T1, T2, and T5 respectively. The numbers of high sample priorities in the sample analysis devices T1, T2, and T5 are 15, 20, and 40 respectively. Then, the sample analysis device T5 has the highest priority. When it is determined that the remaining liquid volumes of multiple external liquid storage barrels of the liquid supply system are not sufficient to support the sample analysis devices T1, T2, and T5 currently in the test state, the processor controls the external liquid storage barrels to supply liquid to T5 first. Since T5 has the most samples with high sample priorities, supplying liquid to T5 first can enable as many samples with high sample priorities as possible to complete the test smoothly when the cleaning liquid is in short supply.

[0163] In an alternative embodiment, the processor 70 determines the priority of the sample analysis device according to the project priority, which may specifically include: the more projects with high project priorities in the sample analysis device, the higher the priority of the sample analysis device.

[0164] In clinical tests, in order to distinguish the priority levels of different test items, the project priority can be set for identification. For example, it can be assumed that the larger the number, the lower the project priority, and the smaller the number, the higher the project priority. The myocardial project has the highest priority, which is 1; the preoperative four-item test has the second highest priority, which is 2; the HCG and PCT tests have the next highest priority, which is 3. If there are more test items Tn with high project priorities in the sample analysis device, the priority of the sample analysis device is higher.

[0165] In an alternative embodiment, the processor 70 determines the priority of the sample analysis device according to the project priority, which may specifically include: the more projects in the preset project set in the sample analysis device, the higher the priority of the sample analysis device. Among them, the preset project set may include test items that are truly urgent in medical opinions. The so-called test items that are truly urgent in medical opinions refer to test items whose TAT time is related to the patient's life and have a more urgent requirement for the sample TAT time.

[0166] In one embodiment, the processor 70 controls the external liquid supply to the sample analysis device according to the load status of each sample analysis device, which may specifically include:

[0167] When it is determined that the remaining liquid volumes of multiple external liquid storage barrels 10 are not sufficient to support the sample analysis devices currently in the test state, the processor 70 supplies liquid to the sample analysis devices currently in the test state according to the sample-related priorities.

[0168] In an alternative embodiment, the processor 70 supplies liquid to each sample analysis device in the test state according to the sample-related priority, including: the sample-related priority includes the sample priority; the processor 70 controls the external liquid storage bucket 10 to preferentially supply liquid to the items of the samples with high priority in each sample analysis device in the test state, realizing adaptive liquid supply in units of samples.

[0169] In an alternative embodiment, the processor 70 supplies liquid to each sample analysis device in the test state according to the sample-related priority, including: the sample-related priority includes the item priority; the processor 70 controls the external liquid storage bucket to preferentially supply liquid to the items with high priority in each sample analysis device in the test state, realizing adaptive liquid supply in units of test items.

[0170] Figure 14 FIG. is a flowchart of a method for a liquid supply system according to an embodiment. The method can be applied to a liquid supply system for externally supplying liquid to one or more sample analysis devices. The liquid supply system may include a plurality of external liquid storage buckets, which are arranged outside the sample analysis devices and are used for storing cleaning liquid. As Figure 14 shown, the method may include:

[0171] Step 101, when external liquid supply is enabled, obtain the load status of each sample analysis device.

[0172] Step 102, according to the load status of each sample analysis device, control the external liquid supply to the sample analysis device.

[0173] In some specific embodiments, step 102 controls the external liquid supply to the sample analysis device according to the load status of each sample analysis device, including: when some sample analysis devices are in the test state and some sample analysis devices are in the idle state, then step 102 controls to reserve a preset number of external liquid storage buckets for each sample analysis device in the idle state, and allocate the remaining external liquid storage buckets to supply liquid to the sample analysis devices in the test state. By reserving a preset number of external liquid storage buckets for the sample analysis devices in the idle state, it can ensure that there is sufficient cleaning liquid available for the sample analysis devices in the idle state when starting the test. Further, in order to make the reservation more reasonable, which can not only ensure that there is sufficient cleaning liquid available for the sample analysis devices in the idle state when starting the test, but also maximize the liquid supply to the sample analysis devices currently in the test state, step 102 may obtain the historical liquid consumption data of each analysis device to calculate the preset number corresponding to each analysis device. Step 102 reserves the external liquid storage buckets according to the calculated preset number corresponding to the sample analysis devices in the idle state.

[0174] When it is determined that the external liquid storage bucket assigned to the sample analysis device in the test state is in an empty state, step 102 controls the external liquid storage bucket reserved for the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state, which can preferably ensure the smooth progress of the test of the sample analysis device in the test state.

[0175] Step 102 can also set the external liquid storage bucket reserved for the sample analysis device in the idle state to a releasable state or a non-releasable state. The so-called releasable state means that the external liquid storage bucket reserved for a certain sample analysis device can be used to supply liquid to other sample analysis devices in some cases, and the so-called non-releasable state means that the external liquid storage bucket reserved for a certain sample analysis device cannot be used to supply liquid to other sample analysis devices. Step 102 can, for example, set the state of the reserved external liquid storage bucket according to the importance of the test items of the sample analysis device in the idle state or the user's input. For example, if the user determines that the sample analysis device M will definitely start testing the sample in a certain test cycle, but the start time of the sample analysis device M for testing is relatively late, and the sample analysis device M is still in the idle state when other sample analysis devices are in the test state, in order to ensure that there is sufficient cleaning liquid supply when the sample analysis device M starts testing, the user can, for example, perform relevant operations on the state setting interface so that the processor sets the external liquid storage bucket reserved for the currently idle sample analysis device M to a non-releasable state.

[0176] Before controlling the external liquid storage bucket 10 reserved for the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state, step 102 also determines whether the external liquid storage bucket reserved for the sample analysis device in the idle state is set to a releasable state; if so, step 102 controls the external liquid storage bucket reserved for the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state.

[0177] Taking the example of external liquid supply from a liquid supply system to two sample analysis devices M1 and M2, it is assumed that the liquid supply system has 6 external storage barrels 10. When M1 is in the test state and M2 is in the idle state, if the processor 70 calculates that the preset quantity of M2 is 1 based on the historical liquid consumption data of M2, the processor 70 controls to reserve 1 barrel for M2 and allocate the remaining 5 barrels for liquid supply to M1. Specifically, if the numbers of the 6 external storage barrels are 1-6, the No. 6 storage barrel can be reserved for the idle M2, and the No. 1-5 storage barrels can be allocated for liquid supply to the test-state M1. When the No. 1-5 external storage barrels 10 allocated to M1 are all exhausted and in the empty state, if M2 is still in the idle state and the No. 6 storage barrel reserved for M2 is set to the releasable state, the processor 70 controls the No. 6 external storage barrel reserved for M2 to supply liquid to the test-state M1, giving priority to ensuring the smooth progress of the currently executing test project.

[0178] In one embodiment, step 102 controls external liquid supply to the sample analysis device according to the load status of each sample analysis device, which may specifically include: each sample analysis device is pre-set with a corresponding external storage barrel; step 102 controls the corresponding external storage barrel to supply liquid to the corresponding sample analysis device in the test state. Among them, step 102 may set the corresponding external storage barrel for each sample analysis device according to the historical liquid consumption data of each sample analysis device.

[0179] When the external storage barrel corresponding to the sample analysis device in the test state is in the empty state, step 102 controls the external storage barrel corresponding to the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state, giving priority to ensuring the smooth progress of the currently executing test project.

[0180] In an alternative embodiment, before controlling the external storage barrel corresponding to the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state, step 102 also determines whether the external storage barrel corresponding to the sample analysis device in the idle state is set to the releasable state; if so, step 102 controls the external storage barrel corresponding to the sample analysis device in the idle state to supply liquid to the sample analysis device in the test state.

[0181] Taking the example of an external liquid supply system supplying liquid to two sample analysis devices M1 and M2, it is assumed that the liquid supply system has 6 external liquid storage barrels numbered 1-6. The processor 70 sets the barrels numbered 1-4 as the external liquid storage barrels 10 corresponding to the sample analysis device M1, and the barrels numbered 5-6 as the external liquid storage barrels 10 corresponding to the sample analysis device M2 according to the historical liquid consumption data of M1 and M2. When M1 is in the test state and M2 is in the idle state, the processor 70 controls the external liquid storage barrels 10 numbered 1-4 to supply liquid to the corresponding sample analysis device M1 in the test state. As the test progresses, when the external liquid storage barrels 10 numbered 1-4 corresponding to the sample analysis device M1 in the test state are in the empty state, the sample analysis device M2 is still in the idle state and its corresponding barrels numbered 5 and 6 are set to the releasable state, then the processor 70 controls the external liquid storage barrels 10 numbered 5 or 6 corresponding to the sample analysis device M2 in the idle state to supply liquid to the sample analysis device M1 in the test state.

[0182] In one embodiment, step 102 controls the external liquid supply to the sample analysis device according to the load status of each sample analysis device, which may specifically include: when it is determined that the remaining liquid volume of multiple external liquid storage barrels is not sufficient to support the current sample analysis devices in the test state, step 102 supplies liquid to each sample analysis device in the test state according to the priority of the sample analysis device, realizing adaptive liquid supply in units of sample analysis devices. In this embodiment, step 102 may determine the priority of the sample analysis device according to the sample priority and / or the project priority. Step 102 supplies liquid to each sample analysis device in the test state according to the priority of the sample analysis device, which may specifically include: step 102 controls the external liquid storage barrel to supply liquid to the sample analysis device with a higher priority first, so as to ensure the normal operation of the sample analysis device with a higher priority first when the cleaning liquid is in short supply.

[0183] In an alternative embodiment, step 102 determines the priority of the sample analysis device according to the sample priority, which may specifically include: the more samples with a high sample priority in the sample analysis device, the higher the priority of the sample analysis device.

[0184] In clinical tests, in order to distinguish the priority of different samples, the sample priority can be set for identification. For example, the sample priority can be divided into three levels: high, medium, and low according to the type of the sample. Specifically, the sample priority of the emergency patient sample can be set to high, the sample priority of the general patient sample can be set to medium, and the sample priority of the physical examination sample can be set to low. Usually, the higher the sample priority, the shorter the required sample turnover time.

[0185] For example, the liquid supply system is connected to a total of five sample analysis devices, namely T1, T2, T3, T4, and T5. Currently, 3 sample analysis devices are in the test state, namely T1, T2, and T5. The numbers of samples with high sample priorities in the sample analysis devices T1, T2, and T5 are 15, 20, and 40 respectively. Then, the sample analysis device T5 has the highest priority. When it is determined that the remaining liquid volumes of multiple external liquid storage barrels of the liquid supply system are insufficient to support the sample analysis devices T1, T2, and T5 currently in the test state, the processor 70 controls the external liquid storage barrels to supply liquid to T5 preferentially. Since T5 has the most samples with high sample priorities, supplying liquid to T5 preferentially can enable as many samples with high sample priorities to complete the test smoothly when the cleaning liquid margin is insufficient.

[0186] In an alternative embodiment, step 102 determines the priority of the sample analysis device according to the project priority, which may specifically include: the more projects with high project priorities in the sample analysis device, the higher the priority of the sample analysis device.

[0187] In clinical tests, in order to distinguish the priority levels of different test items, the project priority can be set for identification. For example, it is assumed that the larger the number, the lower the project priority, and the smaller the number, the higher the project priority. The priority of the test item Tn is the highest, which is 1; the priorities of the test items Na, K, Cl, and Glu are the second highest, which are 2; the priorities of the test items ALT, TP, and UREA are the next highest, which are 3. If there are more test items Tn with high project priorities in the sample analysis device, the priority of the sample analysis device is higher.

[0188] In an alternative embodiment, step 102 determines the priority of the sample analysis device according to the project priority, which may specifically include: the more projects in the preset project set in the sample analysis device, the higher the priority of the sample analysis device. Among them, the preset project set may include test items that are truly urgent in medical opinion. The so-called test items that are truly urgent in medical opinion refer to test items whose TAT time is related to the life of the patient and whose TAT time requirements for samples are more urgent.

[0189] In one embodiment, step 102 controls external liquid supply to the sample analysis device according to the load status of each sample analysis device, which may specifically include:

[0190] When it is determined that the remaining liquid volumes of multiple external liquid storage barrels are insufficient to support the sample analysis devices currently in the test state, step 102 supplies liquid to the sample analysis devices currently in the test state according to the sample-related priorities.

[0191] In an alternative embodiment, step 102 supplies liquid to each sample analysis device in the test state according to the sample-related priority, including: the sample-related priority includes the sample priority; step 102 controls the external liquid storage barrel to preferentially supply liquid to the items of the samples with high priority in each sample analysis device in the test state, realizing adaptive liquid supply based on samples.

[0192] In an alternative embodiment, step 102 supplies liquid to each sample analysis device in the test state according to the sample-related priority, including: the sample-related priority includes the item priority; the processor 70 controls the external liquid storage barrel to preferentially supply liquid to the items with high priority in each sample analysis device in the test state, realizing adaptive liquid supply based on test items.
