Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a sample analyzer and a mixing control method. Background Technology

[0002] Metabolic sample analysis of patients has significant diagnostic value in clinical testing. For example, urine sample analysis helps doctors identify and monitor various diseases. Routine urinalysis in clinical testing generally includes physical property analysis, urine dry chemistry analysis, and urine formed element analysis. By comprehensively evaluating various urine indicators, doctors can promptly detect potential health problems, such as kidney disease and urinary tract infections. However, formed elements in urine samples can precipitate over time, especially in high-concentration samples, where precipitation is more pronounced. This precipitation can lead to inaccurate test results, thus affecting clinical decision-making.

[0003] To ensure accurate test results, it is usually required to homogenize the patient's metabolic samples before testing. However, current technologies typically employ fixed homogenization methods, failing to adequately consider the characteristics and needs of the samples. This singular homogenization method may result in high-value samples not achieving the desired homogenization effect during processing, thus affecting the final test results. In particular, for certain high-concentration urine samples or those containing sediment, traditional homogenization methods may not be effective in resolving sedimentation issues, leading to misdiagnosis or missed diagnosis.

[0081] The present application will be further described below with reference to the accompanying drawings and specific embodiments. The described embodiments should not be considered as limitations on the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0082] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0084] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0087] Metabolic sample analysis of patients has significant diagnostic value in clinical testing. For example, urine sample analysis helps doctors identify and monitor various diseases. Routine urinalysis in clinical testing generally includes physical property analysis, urine dry chemistry analysis, and urine formed element analysis. By comprehensively evaluating various urine indicators, doctors can promptly detect potential health problems, such as kidney disease and urinary tract infections. However, formed elements in urine samples can precipitate over time, especially in high-concentration samples, where precipitation is more pronounced. This precipitation can lead to inaccurate test results, thus affecting clinical decision-making.

[0088] To ensure accurate test results, it is usually required to homogenize the patient's metabolic samples before testing. However, current technologies typically employ fixed homogenization methods, failing to adequately consider the characteristics and needs of the samples. This singular homogenization method may result in high-value samples not achieving the desired homogenization effect during processing, thus affecting the final test results. In particular, for certain high-concentration urine samples or those containing sediment, traditional homogenization methods may not be effective in resolving sedimentation issues, leading to misdiagnosis or missed diagnosis.

[0089] Based on this, embodiments of this application provide a sample analyzer and a mixing control method, which can automatically identify high-value samples according to the characteristics of the samples and adjust the mixing intensity to improve the accuracy and efficiency of the detection results.

[0090] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0091] Firstly, see [the following] Figure 1 As shown, Figure 1 This is a schematic diagram of an optional sample analyzer provided in an embodiment of this application. The sample analyzer 100 includes a sample injection device 101, an information acquisition device 102, a mixing device 103, a detection device 104, and a control device 105. The sample injection device 101 is used to load or store samples, the information acquisition device 102 is used to acquire sample information, the mixing device 103 is used to mix the samples, the detection device 104 is used to detect the mixed samples, and the control device 105 is communicatively connected to the sample injection device 101, the information acquisition device 102, the mixing device 103, and the detection device 104.

[0092] In some alternative embodiments, the sample introduction device 101 may be a test tube tray containing one or more hollow tubes, each hollow tube loading or storing samples from different test subjects, and then the mixing device 103 mixing the samples in each hollow tube.

[0093] In some alternative embodiments, the sample introduction device 101 may also be a test tube clamp for gripping hollow tubes, which are loaded or stored with samples from different test subjects. The test tube clamp is used for expedited analysis in emergency departments. When a hollow tube is placed in the test tube clamp, the sample in the test tube can be analyzed and processed first.

[0094] The control device 105 is used to determine the physical characteristics of the sample based on the sample information and to make a judgment based on the physical characteristics. If the physical characteristics meet the first preset condition, the control device 103 is used to perform a first mixing operation on the sample. If the physical characteristics meet the second preset condition, the control device 103 is used to perform a second mixing operation on the sample. The intensity of the first mixing operation is greater than that of the second mixing operation.

[0095] It should be noted that the sample is a liquid sample, and the physical characteristics corresponding to its sample information include the sample's color, transparency, and viscosity, which are not specifically limited in this application.

[0096] If the physical characteristics of the sample meet the first preset condition, it indicates that the sample is a high-value urine sample, and the mixing device 103 needs to be controlled to perform a first mixing operation on the sample; if the physical characteristics of the sample meet the second preset condition, it indicates that the sample is a low-value sample, and the mixing device 103 needs to be controlled to perform a second mixing operation on the sample.

[0097] Therefore, the sample analyzer 100 of this application, by providing a sample introduction device 101, an information acquisition device 102, a mixing device 103, a detection device 104, and a control device 105, can automatically identify high-value samples and low-value samples according to the physical characteristics of the samples, and adjust the mixing intensity accordingly to improve the accuracy and efficiency of the detection results.

[0098] The sample can be a urine sample, a blood sample, a prostatic fluid sample, a tissue fluid sample, or a saliva sample. This application does not make any specific limitations. Preferred, the sample provided in this application embodiment is a urine sample. When the sample is a urine sample, the physical characteristics of the urine sample include urine sample color, urine sample transparency, urine sample viscosity, urine sample volume, etc.

[0099] In some optional embodiments, when the sample is a urine sample, the first preset condition can be set to the urine sample color being dark yellow or reddish-brown, or the first preset condition being the urine sample transparency parameter being less than 40%, or the first preset condition being the urine sample viscosity being greater than 1.030 or less than 1.010.

[0100] In some optional embodiments, when the sample is a urine sample, the second preset condition is that the urine sample is transparent or pale yellow, or the first preset condition is that the urine sample transparency parameter is higher than or equal to 40%, or the first preset condition is that the urine sample viscosity is less than 1.030 or equal to and greater than or equal to 1.010.

[0101] In some optional embodiments, provided that the intensity of the first mixing operation is greater than that of the second mixing operation, the first mixing operation and the second mixing operation may employ the same mixing method and satisfy at least one of the following conditions: the mixing duration of the first mixing operation is greater than that of the second mixing operation; the number of mixing operations in the first mixing operation is greater than the number of mixing operations in the second mixing operation; and the liquid agitation intensity of the first mixing operation is greater than that of the second mixing operation.

[0102] The first mixing operation and the second mixing operation adopt the same mixing method, which may include: both the first mixing operation and the second mixing operation include a first mixing step and a second mixing step; or, both the first mixing operation and the second mixing operation include a first mixing step; or, both the first mixing operation and the second mixing operation include a second mixing step.

[0103] It should be noted that the first mixing step involves the mixing device 103 taking in a certain amount of sample liquid and then regurgitating it to mix the sample; the second mixing step involves the mixing device 103 expelling air bubbles from the sample to mix the sample by expelling air bubbles.

[0104] Furthermore, when both the first mixing operation and the second mixing operation include a first mixing step, in order to satisfy that the intensity of the first mixing operation is greater than that of the second mixing operation, it is only necessary to satisfy at least one of the following conditions: the execution time of the first mixing step in the first mixing operation is greater than the execution time of the first mixing step in the second mixing operation; the number of times the first mixing step is executed in the first mixing operation is greater than the number of times the first mixing step is executed in the second mixing operation; and the liquid absorption and expulsion intensity of the first mixing step in the first mixing operation is greater than the liquid absorption and expulsion intensity of the first mixing step in the second mixing operation.

[0105] Furthermore, when both the first mixing operation and the second mixing operation include a second mixing step, in order to satisfy that the intensity of the first mixing operation is greater than that of the second mixing operation, it is only necessary to satisfy at least one of the following conditions: the execution time of the second mixing step in the first mixing operation is greater than the execution time of the second mixing step in the second mixing operation; the number of times the second mixing step is executed in the first mixing operation is greater than the number of times the second mixing step is executed in the second mixing operation; and the bubble expulsion intensity of the second mixing step in the first mixing operation is greater than the bubble expulsion intensity of the second mixing step in the second mixing operation.

[0106] Furthermore, when both the first and second mixing operations include a first mixing step and a second mixing step, in order to ensure that the intensity of the first mixing operation is greater than the intensity of the second mixing operation, it is necessary to control the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation to be greater than the intensity of the first mixing step and the intensity of the second mixing step in the second mixing operation. The intensity of the first mixing step is related to the following parameters: aspirated / expelled liquid volume, aspirated / expelled times, and aspirated / expelled duration. The intensity of the second mixing step is related to the following parameters: expelled gas volume, expelled gas flow rate, expelled gas duration, and expelled gas times.

[0107] Preferably, taking the aspiration and expulsion time of the first mixing step and the bubble expulsion time of the second mixing step as examples, when the aspiration and expulsion time of the first mixing step is equal to the bubble expulsion time of the second mixing step, the intensity of the first mixing step is equal to the intensity of the second mixing step. Therefore, controlling the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation to be greater than the intensity of the first mixing step and the intensity of the second mixing step in the second mixing operation includes, but is not limited to, the following operational examples:

[0108] The first operational example is to control the aspiration and expulsion time (6s) of the first mixing step in the first mixing operation to be greater than the aspiration and expulsion time (5s) of the first mixing step in the second mixing operation, and then control the expulsion time (5s) of the second mixing step in the first mixing operation to be greater than the expulsion time (2s) of the second mixing step in the second mixing operation.

[0109] The second example of operation is to control the bubble release time (6s) of the second mixing step in the first mixing operation to be greater than the bubble release time (5s) of the second mixing step in the second mixing operation, and then control the suction and release time (6s) of the first mixing step in the first mixing operation to be greater than the suction and release time (2s) of the first mixing step in the second mixing operation.

[0110] The third operational example is to control the bubble release time (2s) of the second mixing step in the first mixing operation to be less than the bubble release time (5s) of the second mixing step in the second mixing operation, and then control the suction and release time (8s) of the first mixing step in the first mixing operation to be greater than the suction and release time (2s) of the first mixing step in the second mixing operation.

[0111] The fourth operational example is to control the aspiration and expulsion time (6s) of the first mixing step in the first mixing operation to be greater than the aspiration and expulsion time (1s) of the first mixing step in the second mixing operation, and then control the expulsion time (3s) of the second mixing step in the first mixing operation to be less than the expulsion time (4s) of the second mixing step in the second mixing operation.

[0112] The fifth operational example is to control the bubble release time (5s) of the second mixing step in the first mixing operation to be equal to the bubble release time (5s) of the second mixing step in the second mixing operation, and then control the aspiration and expulsion time (6s) of the first mixing step in the first mixing operation to be less than the aspiration and expulsion time (2s) of the first mixing step in the second mixing operation.

[0113] The sixth operational example is the first operational example, in which the aspiration and expulsion time (6s) of the first mixing step in the first mixing operation is equal to the aspiration and expulsion time (6s) of the first mixing step in the second mixing operation, and then the expulsion time (4s) of the second mixing step in the first mixing operation is greater than the expulsion time (3s) of the second mixing step in the second mixing operation.

[0114] Furthermore, in some optional embodiments, provided that the intensity of the first mixing operation is greater than that of the second mixing operation, the first mixing operation and the second mixing operation may employ different mixing methods, which may include: the first mixing operation including a first mixing step and a second mixing step, and the second mixing operation including a first mixing step; or, the first mixing operation including a first mixing step and a second mixing step, and the second mixing operation including a second mixing step.

[0115] It should be noted that the first mixing step involves the mixing device 103 taking in a certain amount of sample liquid and then regurgitating it to mix the sample; the second mixing step involves the mixing device 103 expelling air bubbles from the sample to mix the sample by expelling air bubbles.

[0116] Furthermore, when the first mixing operation includes a first mixing step and a second mixing step, and the second mixing operation includes a first mixing step, in order to ensure that the intensity of the first mixing operation is greater than the intensity of the second mixing operation, it is necessary to control the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation to be greater than the intensity of the first mixing step in the second mixing operation. The intensity of the first mixing step is related to the following parameters: aspirated / expelled liquid volume, aspirated / expelled times, and aspirated / expelled duration; the intensity of the second mixing step is related to the following parameters: expelled gas volume, expelled gas flow rate, expelled gas duration, and expelled gas frequency.

[0117] Preferably, taking the amount of liquid absorbed / expelled in the first mixing step and the amount of gas expelled in the second mixing step as an example, when the amount of liquid absorbed / expelled in the first mixing step is equal to the amount of gas expelled in the second mixing step, the intensity of the first mixing step is equal to the intensity of the second mixing step. Therefore, the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation are greater than the intensity of the first mixing step in the second mixing operation, including but not limited to the following operational examples:

[0118] The first operational example is to control the volume of aspirated / expelled liquid (5 mL) in the first mixing step of the first mixing operation to be greater than the volume of aspirated / expelled liquid (4 mL) in the first mixing step of the second mixing operation.

[0119] The second example of operation is to control the volume of aspirated / expelled liquid (4 mL) in the first mixing step of the first mixing operation to be equal to the volume of aspirated / expelled liquid (4 mL) in the first mixing step of the second mixing operation.

[0120] The third operational example involves controlling the amount of liquid aspirated / expelled in the first mixing step of the first mixing operation (3 mL) to be less than the amount of liquid aspirated / expelled in the first mixing step of the second mixing operation (5 mL), and then controlling the amount of gas expelled in the second mixing step of the first mixing operation (3 mL) to be greater than the difference between the amount of liquid aspirated / expelled in the first mixing step of the second mixing operation and the amount of liquid aspirated / expelled in the first mixing step of the first mixing operation (5 mL - 3 mL = 2 mL).

[0121] Furthermore, when the first mixing operation includes a first mixing step and a second mixing step, and the second mixing operation includes a second mixing step, in order to satisfy that the intensity of the first mixing operation is greater than the intensity of the second mixing operation, it is necessary to control that the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation are greater than the intensity of the second mixing step in the second mixing operation.

[0122] Preferably, taking the number of aspirations and expulsions in the first mixing step and the number of bubble expulsions in the second mixing step as an example, when the number of aspirations and expulsions in the first mixing step is equal to the number of bubble expulsions in the second mixing step, the intensity of the first mixing step is equal to the intensity of the second mixing step. Therefore, the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation are greater than the intensity of the second mixing step in the second mixing operation, including but not limited to the following operational examples:

[0123] The first operational example is to control the number of times the second mixing step in the first mixing operation is vented (10 times) to be greater than the number of times the second mixing step in the second mixing operation is vented (8 times).

[0124] The second operational example is to control the number of times (10 times) the first mixing step in the second mixing operation to be equal to the number of times (10 times) the second mixing step in the second mixing operation.

[0125] The third operational example is to control the number of times the second mixing step in the first mixing operation exhales (6 times) to be less than the number of times the second mixing step in the second mixing operation exhales (8 times), and then control the number of times the first mixing step in the first mixing operation exhales (6 times) to be greater than the difference between the number of times the first mixing step in the second mixing operation exhales (8 times - 6 times = 2 times).

[0126] In some alternative embodiments, the sample analyzer 100 further includes a sampling assembly for taking a sample from the mixed urine sample and delivering it to the detection device 104 for detection.

[0127] In addition, in some alternative embodiments, the mixing device 103 includes a sampling assembly for mixing the sample, then aspirating at least a portion of the mixed sample and delivering it to the detection device 104 for detection.

[0128] The sampling component can be a sample needle, which is directly inserted into the hollow tube. Then, a certain amount of sample liquid is drawn from the mixed sample using the principle of negative pressure. The sample needle is then removed from the hollow tube and transferred to the detection device 104. Finally, the sample liquid in the sample needle is delivered to the detection device 104 for detection using the principle of positive pressure.

[0129] Furthermore, the sampling assembly can also be a sampling pump or a pipette, and its sampling principle is similar to that of the sample needle mentioned above, which will not be repeated here.

[0130] It should be noted that the sample aspiration assembly can also perform at least one of the following mixing operations on the sample liquid: aspirating a certain amount of sample liquid and regurgitating it to mix the sample, expelling air bubbles into the sample to mix the sample by expelling air bubbles, or moving back and forth in the sample to stir and mix the sample.

[0131] Furthermore, the control device 105 can adjust the intensity of the first mixing operation and the second mixing operation by controlling at least one of the following parameters of the sampling assembly: the amount of liquid aspirated and expelled by the sampling assembly, the number of times the sampling assembly aspirates and expells liquid, the amount of gas expelled by the sampling assembly, the gas flow rate of the expelled gas from the sampling assembly, the duration of the expelled gas from the sampling assembly, and the number of times the sampling assembly expells gas.

[0132] In some alternative embodiments, the mixing device 103 further includes a shaking component for shaking the sample to achieve mixing.

[0133] Preferably, the rocking assembly is equipped with a motor or pneumatic device to provide a stable rocking power source, and the rocking assembly is also equipped with a connecting rod, eccentric wheel or ball bearing slide to convert the rotation or linear motion of the power unit into a specific rocking mode (such as horizontal rocking, circular rocking, linear rocking or pulse rocking).

[0134] In some optional embodiments, the information acquisition device 102 includes a sensor for identifying the color of a sample; preferably, the sensor is one of an image sensor, a color sensor, or an optical sensor; wherein, taking a urine sample as an example, the sensor is used to identify the color of the urine sample.

[0135] It should be noted that when the sensor is an image sensor, the image sensor performs image recognition on the sample to obtain the sample color; when the sensor is a color sensor, the color sensor performs color recognition on the sample to obtain the sample color; and when the sensor is an optical sensor, the image sensor performs optical detection on the sample to obtain the sample color.

[0136] Furthermore, when the sample is a urine sample, the control device 105 is also used to: determine the urine color parameters of the sample based on the urine sample color information obtained by the information acquisition device 102, and make a judgment based on the urine color parameters. If the urine color parameters meet the first preset condition, the urine sample is judged to be a high-value sample and the mixing device 103 is controlled to perform the first mixing operation; if the urine color parameters meet the second preset condition, the urine sample is judged to be a low-value sample and the mixing device 103 is controlled to perform the second mixing operation.

[0137] It should be noted that when the urine color parameter is greater than the preset threshold, the color of the urine sample meets the first preset condition; when the urine color parameter is less than or equal to the preset threshold, the color of the urine sample meets the second preset condition.

[0138] The urine color parameter can be expressed in RGB color mode, CMYK color mode, HSB color mode, or Lab color mode; this application does not impose any specific limitation.

[0139] In some optional embodiments, taking the RGB color mode as an example, when the urine color parameter is greater than the preset threshold RGB (140, 119, 39), the color of the urine sample is determined to meet the first preset condition; when the urine color parameter is less than or equal to the preset threshold RGB (140, 119, 39), the color of the urine sample is determined to meet the second preset condition.

[0140] In some optional embodiments, taking the CMYK color mode as an example, when the urine color parameter is greater than the preset threshold CMYK(5,30,100,0), the color of the urine sample is determined to meet the first preset condition; when the urine color parameter is less than or equal to the preset threshold CMYK(5,30,100,0), the color of the urine sample is determined to meet the second preset condition.

[0141] Accordingly, the color mode of the preset threshold is consistent with the color mode of the urine color parameter. For example, when the urine color parameter is expressed in RGB color mode, the color mode of the preset threshold is RGB color mode; when the urine color parameter is expressed in CMYK color mode, the color mode of the preset threshold is CMYK color mode.

[0142] Furthermore, the information acquisition device 102 is used to identify the color of the urine sample and the identification code information of the urine sample. That is, in some optional embodiments, the sensor in the information acquisition device 102 used to identify the color of the urine sample can also be used to identify the identification code information of the urine sample; or, in other optional embodiments, the information acquisition device 102 includes a sensor for identifying the color of the urine sample and a sensor for identifying the identification code information of the urine sample.

[0143] Preferably, the information acquisition device 102 includes an image sensor and a rotating device. The rotating device is used to rotate the urine sample, and the image sensor is used to collect the identification code information of the urine sample container and the color information of the urine sample during the rotation of the urine sample.

[0144] Preferably, the image sensor is a high-resolution sensor to ensure clear representation of microscopic details of the sample, such as particle deposits or impurity morphology.

[0145] Preferably, the rotating device can generate centrifugal force through rotation to make the components in the urine sample more evenly distributed, and at the same time, the rotation can adjust the reflection or refraction angle in the sample so that the image sensor can obtain the best imaging effect.

[0146] Since the urine sample container has identification code information, the workflow of the information acquisition device 102 is as follows: the urine sample container is placed in the sample holder of the rotating device and fixed, and then the rotating device is started and the sample is driven to rotate according to the set speed and angle. When the rotating device rotates the identification code information of the urine sample container into the recognizable range of the image sensor, the image sensor captures the current frame image and performs image recognition on the frame image to obtain the identification code information of the urine sample container.

[0147] Furthermore, the sample analyzer 100 also includes a sample transfer mechanism, which is used to transfer the urine sample in the sample injection device 101 to the rotating device. The sample transfer mechanism will precisely move the urine sample container to the designated position of the rotating device according to the control signal inside the sample analyzer 100, so as to ensure the accuracy of subsequent processing or analysis.

[0148] It should be noted that the sample transfer mechanism includes a drive unit, a gripping unit, a track device, a sensor module, and a control system. The drive unit uses a motor or pneumatic device to grip, lift, move, and release the sample container. The gripping unit uses mechanical claws, suction devices, or other means to hold the sample container, ensuring that the sample container is stable and does not fall off during movement. The track uses linear slide rails or rotating rails to achieve multi-directional sample transfer. The sensor module is used to detect the presence, position, and status of the sample container to ensure accurate operation.

[0149] Secondly, see Figure 2 As shown, Figure 2This is a schematic diagram of another optional sample analyzer provided in an embodiment of this application. The sample analyzer 200 includes a sample injection device 201, an information acquisition device 202, a mixing device 203, a detection device 204, and a control device 205. The sample injection device 201 is used to load or store the sample. The information acquisition device 202 is used to acquire sample information. The mixing device 203 is used to mix the sample. The detection device 204 is used to detect the mixed sample. The control device 205 is communicatively connected to the sample injection device 201, the information acquisition device 202, the mixing device 203, and the detection device 204.

[0150] In some alternative embodiments, the sample introduction device 201 may be a test tube tray containing one or more hollow tubes, each hollow tube loading or storing samples from different test subjects, and then the mixing device 203 mixing the samples in each hollow tube.

[0151] In some alternative embodiments, the sample introduction device 201 may also be a test tube clamp for gripping hollow tubes, which are loaded or stored with samples from different test subjects. The test tube clamp is used for expedited analysis in emergency departments. When a hollow tube is placed in the test tube clamp, the sample in the test tube can be analyzed and processed first.

[0152] Furthermore, the control device 205 is used to analyze and judge the sample information of the sample acquired by the information acquisition device 202. If the sample information meets the first preset condition, the control device 203 is controlled to perform a first mixing operation on the sample. If the sample information meets the second preset condition, the control device 203 is controlled to perform a second mixing operation on the sample. The intensity of the first mixing operation is greater than that of the second mixing operation.

[0153] It should be noted that the sample is a liquid sample.

[0154] In some optional embodiments, the sample information includes a sample identifier. When the sample identifier is a first identifier, the sample information meets a first preset condition. When the sample identifier is a second identifier, the sample information meets a second preset condition. The first identifier includes at least one of a high-value sample identifier, an abnormal sample identifier, or a suspicious sample identifier, and the second identifier is a regular sample identifier.

[0155] In some optional embodiments, the sample information includes the department source information of the sample. When the department source information is a preset department, the sample information meets a first preset condition. When the department source information is from another source outside the preset department, the sample information meets a second preset condition.

[0156] In some optional embodiments, the sample information includes the sampling time of the sample. The control device 205 is also used to determine the time interval between the current time and the sampling time based on the sampling time. When the time interval is greater than a preset time threshold, the sample information satisfies a first preset condition. When the time interval is less than or equal to the preset time threshold, the sample information satisfies a second preset condition.

[0157] In some optional embodiments, the sample information includes the time interval between the sampling time of the sample and the current time. When the time interval is greater than a preset time threshold, the sample information satisfies a first preset condition. When the time interval is less than or equal to the preset time threshold, the sample information satisfies a second preset condition.

[0158] Furthermore, the sample information also includes the physical characteristics of the sample, including the sample's color.

[0159] Therefore, the sample analyzer 200 of this application, by being equipped with a sample introduction device 201, an information acquisition device 202, a mixing device 203, a detection device 204, and a control device 205, can automatically identify high-value samples and low-value samples based on the diverse sample information in the sample, and adjust the mixing intensity accordingly to improve the accuracy and efficiency of the detection results.

[0160] In some optional embodiments, the information acquisition device 202 includes an image sensor or barcode scanner for identifying the identification code information of the sample. The identification code information includes sample information. The identification code information may be displayed in the form of a QR code or a barcode. This application does not make any specific limitation.

[0161] Furthermore, in some optional embodiments, when the image sensor recognizes the QR code on the hollow tube corresponding to the sample, the information acquisition device 202 captures the current frame image, then performs image recognition on the current frame image to obtain the identification code information corresponding to the sample, and finally performs data parsing on the identification code information to obtain the sample information corresponding to the sample.

[0162] Furthermore, in some optional embodiments, after the barcode scanner scans the complete barcode on the hollow tube corresponding to the sample, the information acquisition device 202 identifies the current barcode, obtains the identification code information corresponding to the sample, and finally performs data parsing on the identification code information to obtain the sample information corresponding to the sample.

[0163] The sample can be a urine sample, a blood sample, a prostatic fluid sample, a tissue fluid sample, or a saliva sample. This application does not make any specific limitations. Preferred, the sample provided in this application embodiment is a urine sample. When the sample is a urine sample, the sample information of the urine sample includes the sample identifier of the urine sample, the department source information of the urine sample, the sampling time of the urine sample, the time interval between the sampling time of the urine sample and the current time, and the physical characteristics of the urine sample, wherein the physical characteristics include the color of the urine sample.

[0164] Furthermore, the identification device also includes a sensor for identifying the color of the sample; preferably, the sensor is one of an image sensor, a color sensor, or an optical sensor; wherein, taking a urine sample as an example, the sensor is used to identify the color of the urine sample.

[0165] It should be noted that when the sensor is an image sensor, the image sensor performs image recognition on the sample to obtain the sample color; when the sensor is a color sensor, the color sensor performs color recognition on the sample to obtain the sample color; and when the sensor is an optical sensor, the image sensor performs optical detection on the sample to obtain the sample color.

[0166] Furthermore, when the sample is a urine sample, the control device 205 is also used to: determine the urine color parameters of the sample based on the urine sample color information obtained by the information acquisition device 202, and make a judgment based on the urine color parameters. If the urine color parameters meet the first preset condition, the urine sample is judged to be a high-value sample and the mixing device 203 is controlled to perform a first mixing operation; if the urine color parameters meet the second preset condition, the urine sample is judged to be a low-value sample and the mixing device 203 is controlled to perform a second mixing operation.

[0167] It should be noted that when the urine color parameter is greater than the preset threshold, the color of the urine sample meets the first preset condition; when the urine color parameter is less than or equal to the preset threshold, the color of the urine sample meets the second preset condition.

[0168] The urine color parameter can be expressed in RGB color mode, CMYK color mode, HSB color mode, or Lab color mode; this application does not impose any specific limitation.

[0169] In some optional embodiments, taking the HSB color mode as an example, when the urine color parameter is greater than the preset threshold HSB (35, 60, 65), the color of the urine sample is determined to meet the first preset condition; when the urine color parameter is less than or equal to the preset threshold HSB (35, 60, 65), the color of the urine sample is determined to meet the second preset condition.

[0170] In some optional embodiments, taking the Lab color mode as an example, when the urine color parameter is greater than the preset threshold Lab(56,17,44), the color of the urine sample is determined to meet the first preset condition; when the urine color parameter is less than or equal to the preset threshold Lab(56,17,44), the color of the urine sample is determined to meet the second preset condition.

[0171] Accordingly, the color mode of the preset threshold is consistent with the color mode of the urine color parameter. For example, when the urine color parameter is expressed in HSB color mode, the color mode of the preset threshold is HSB color mode; when the urine color parameter is expressed in Lab color mode, the color mode of the preset threshold is Lab color mode.

[0172] Furthermore, in some optional embodiments, the mixing device 203 includes a sample suction component, which is used to mix the sample, then aspirate at least a portion of the mixed sample and deliver it to the detection device 204 for detection.

[0173] The sampling component can be a sample needle, which is directly inserted into the hollow tube. Then, a certain amount of sample liquid is drawn from the mixed sample using the principle of negative pressure. The sample needle is then removed from the hollow tube and transferred to the detection device 204. Finally, the sample liquid in the sample needle is delivered to the detection device 204 for detection using the principle of positive pressure.

[0174] Furthermore, the sampling assembly can also be a sampling pump or a pipette, and its sampling principle is similar to that of the sample needle mentioned above, which will not be repeated here.

[0175] It should be noted that the sample aspiration assembly performs at least one of the following mixing operations on the sample liquid: aspirates a certain amount of sample liquid and spits it back to mix the sample, spits out air bubbles in the sample to mix the sample by expelling air bubbles, or moves back and forth in the sample to stir and mix the sample.

[0176] Furthermore, the control device 205 can adjust the intensity of the first mixing operation and the second mixing operation by controlling at least one of the following parameters of the sampling assembly: the amount of liquid aspirated and expelled by the sampling assembly, the number of times the sampling assembly aspirates and expells liquid, the amount of gas expelled by the sampling assembly, the gas flow rate of the expelled gas from the sampling assembly, the duration of the expelled gas from the sampling assembly, and the number of times the sampling assembly expells gas.

[0177] In some alternative embodiments, the mixing device 203 further includes a shaking component for shaking the sample to achieve mixing.

[0178] Preferably, the rocking assembly is equipped with a motor or pneumatic device to provide a stable rocking power source, and the rocking assembly is also equipped with a connecting rod, eccentric wheel or ball bearing slide to convert the rotation or linear motion of the power unit into a specific rocking mode (such as horizontal rocking, circular rocking, linear rocking or pulse rocking).

[0179] Preferably, the information acquisition device 202 includes an image sensor and a rotating device. The rotating device is used to rotate the urine sample, and the image sensor is used to collect the identification code information of the urine sample container and the color information of the urine sample during the rotation of the urine sample.

[0180] Preferably, the image sensor is a high-resolution sensor to ensure clear representation of microscopic details of the sample, such as particle deposits or impurity morphology.

[0181] Preferably, the rotating device can generate centrifugal force through rotation to make the components in the urine sample more evenly distributed, and at the same time, the rotation can adjust the reflection or refraction angle in the sample so that the image sensor can obtain the best imaging effect.

[0182] Furthermore, the urine sample container has a corresponding identification code. The workflow of the information acquisition device 202 is as follows: the urine sample container is placed in the sample holder of the rotating device and fixed. Then, the rotating device is started and the sample is driven to rotate according to the set speed and angle. When the rotating device rotates the identification code of the urine sample container into the recognizable range of the image sensor, the image sensor captures the current frame image and performs image recognition on the frame image to obtain the identification code information of the urine sample container. Alternatively, the scanner scans the identification code of the urine sample container to obtain the identification code information of the urine sample container.

[0183] Furthermore, the sample analyzer 200 also includes a sample transfer mechanism, which is used to transfer the urine sample in the sample injection device 201 to the rotating device. The sample transfer mechanism will precisely move the urine sample container to the designated position of the rotating device according to the control signal inside the sample analyzer 200 to ensure the accuracy of subsequent processing or analysis.

[0184] Furthermore, in some optional embodiments, provided that the intensity of the first mixing operation is greater than that of the second mixing operation, the first mixing operation and the second mixing operation can adopt the same mixing method and satisfy at least one of the following conditions: the mixing time of the first mixing operation is greater than the mixing time of the second mixing operation; the number of mixing operations in the first mixing operation is greater than the number of mixing operations in the second mixing operation; the liquid agitation intensity of the first mixing operation is greater than the liquid agitation intensity of the second mixing operation.

[0185] The first mixing operation and the second mixing operation adopt the same mixing method, which may include: both the first mixing operation and the second mixing operation include a first mixing step and a second mixing step; or, both the first mixing operation and the second mixing operation include a first mixing step; or, both the first mixing operation and the second mixing operation include a second mixing step.

[0186] It should be noted that the first mixing step involves the mixing device 203 drawing a certain amount of sample liquid and regurgitating it to mix the sample; the second mixing step involves the mixing device 203 releasing air bubbles into the sample to mix the sample by releasing air bubbles.

[0187] Furthermore, when both the first mixing operation and the second mixing operation include a first mixing step, in order to satisfy that the intensity of the first mixing operation is greater than that of the second mixing operation, it is only necessary to satisfy at least one of the following conditions: the execution time of the first mixing step in the first mixing operation is greater than the execution time of the first mixing step in the second mixing operation; the number of times the first mixing step is executed in the first mixing operation is greater than the number of times the first mixing step is executed in the second mixing operation; and the liquid absorption and expulsion intensity of the first mixing step in the first mixing operation is greater than the liquid absorption and expulsion intensity of the first mixing step in the second mixing operation.

[0188] Furthermore, when both the first mixing operation and the second mixing operation include a second mixing step, in order to satisfy that the intensity of the first mixing operation is greater than that of the second mixing operation, it is only necessary to satisfy at least one of the following conditions: the execution time of the second mixing step in the first mixing operation is greater than the execution time of the second mixing step in the second mixing operation; the number of times the second mixing step is executed in the first mixing operation is greater than the number of times the second mixing step is executed in the second mixing operation; and the bubble expulsion intensity of the second mixing step in the first mixing operation is greater than the bubble expulsion intensity of the second mixing step in the second mixing operation.

[0189] Furthermore, when both the first and second mixing operations include a first mixing step and a second mixing step, in order to ensure that the intensity of the first mixing operation is greater than the intensity of the second mixing operation, it is necessary to control the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation to be greater than the intensity of the first mixing step and the intensity of the second mixing step in the second mixing operation. The intensity of the first mixing step is related to the following parameters: aspirated / expelled liquid volume, aspirated / expelled times, and aspirated / expelled duration. The intensity of the second mixing step is related to the following parameters: expelled gas volume, expelled gas flow rate, expelled gas duration, and expelled gas times.

[0190] Preferably, taking the aspiration and expulsion time of the first mixing step and the bubble expulsion time of the second mixing step as examples, when the aspiration and expulsion time of the first mixing step is equal to the bubble expulsion time of the second mixing step, the intensity of the first mixing step is equal to the intensity of the second mixing step. Therefore, controlling the intensity of the first mixing step in the first mixing operation to be greater than the intensity of the first mixing step in the second mixing operation includes, but is not limited to, the following operational examples:

[0191] The first operational example is to control the aspiration and expulsion time (6s) of the first mixing step in the first mixing operation to be greater than the aspiration and expulsion time (5s) of the first mixing step in the second mixing operation, and then control the expulsion time (5s) of the second mixing step in the first mixing operation to be greater than the expulsion time (2s) of the second mixing step in the second mixing operation.

[0192] The second example of operation is to control the bubble release time (6s) of the second mixing step in the first mixing operation to be greater than the bubble release time (5s) of the second mixing step in the second mixing operation, and then control the suction and release time (6s) of the first mixing step in the first mixing operation to be greater than the suction and release time (2s) of the first mixing step in the second mixing operation.

[0193] The third example of operation is to control the bubble release time (2s) of the second mixing step in the first mixing operation to be less than the bubble release time (5s) of the second mixing step in the second mixing operation, and then control the suction and release time (8s) of the first mixing step in the first mixing operation to be greater than the suction and release time (2s) of the first mixing step in the second mixing operation.

[0194] The fourth operational example is to control the aspiration and expulsion time (6s) of the first mixing step in the first mixing operation to be greater than the aspiration and expulsion time (1s) of the first mixing step in the second mixing operation, and then control the expulsion time (3s) of the second mixing step in the first mixing operation to be less than the expulsion time (4s) of the second mixing step in the second mixing operation.

[0195] The fifth operational example is to control the bubble release time (5s) of the second mixing step in the first mixing operation to be equal to the bubble release time (5s) of the second mixing step in the second mixing operation, and then control the aspiration and expulsion time (6s) of the first mixing step in the first mixing operation to be less than the aspiration and expulsion time (2s) of the first mixing step in the second mixing operation.

[0196] The sixth operational example is the first operational example, in which the aspiration and expulsion time (6s) of the first mixing step in the first mixing operation is equal to the aspiration and expulsion time (6s) of the first mixing step in the second mixing operation, and then the expulsion time (4s) of the second mixing step in the first mixing operation is greater than the expulsion time (3s) of the second mixing step in the second mixing operation.

[0197] Furthermore, in some optional embodiments, provided that the intensity of the first mixing operation is greater than that of the second mixing operation, the first mixing operation and the second mixing operation may employ different mixing methods, which may include: the first mixing operation including a first mixing step and a second mixing step, and the second mixing operation including a first mixing step; or, the first mixing operation including a first mixing step and a second mixing step, and the second mixing operation including a second mixing step.

[0198] It should be noted that the first mixing step involves the mixing device 203 drawing a certain amount of sample liquid and regurgitating it to mix the sample; the second mixing step involves the mixing device 203 releasing air bubbles into the sample to mix the sample by releasing air bubbles.

[0199] Furthermore, when the first mixing operation includes a first mixing step and a second mixing step, and the second mixing operation includes a first mixing step, in order to ensure that the intensity of the first mixing operation is greater than the intensity of the second mixing operation, it is necessary to control the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation to be greater than the intensity of the first mixing step in the second mixing operation. The intensity of the first mixing step is related to the following parameters: aspirated / expelled liquid volume, aspirated / expelled times, and aspirated / expelled duration; the intensity of the second mixing step is related to the following parameters: expelled gas volume, expelled gas flow rate, expelled gas duration, and expelled gas frequency.

[0200] Preferably, taking the amount of liquid absorbed / expelled in the first mixing step and the amount of gas expelled in the second mixing step as an example, when the amount of liquid absorbed / expelled in the first mixing step is equal to the amount of gas expelled in the second mixing step, the intensity of the first mixing step is equal to the intensity of the second mixing step. Therefore, the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation are greater than the intensity of the first mixing step in the second mixing operation, including but not limited to the following operational examples:

[0201] The first operational example is to control the volume of aspirated / expelled liquid (5 mL) in the first mixing step of the first mixing operation to be greater than the volume of aspirated / expelled liquid (4 mL) in the first mixing step of the second mixing operation.

[0202] The second example of operation is to control the volume of aspirated / expelled liquid (4 mL) in the first mixing step of the first mixing operation to be equal to the volume of aspirated / expelled liquid (4 mL) in the first mixing step of the second mixing operation.

[0203] The third operational example involves controlling the amount of liquid aspirated / expelled in the first mixing step of the first mixing operation (3 mL) to be less than the amount of liquid aspirated / expelled in the first mixing step of the second mixing operation (5 mL), and then controlling the amount of gas expelled in the second mixing step of the first mixing operation (3 mL) to be greater than the difference between the amount of liquid aspirated / expelled in the first mixing step of the second mixing operation and the amount of liquid aspirated / expelled in the first mixing step of the first mixing operation (5 mL - 3 mL = 2 mL).

[0204] Furthermore, when the first mixing operation includes a first mixing step and a second mixing step, and the second mixing operation includes a second mixing step, in order to satisfy that the intensity of the first mixing operation is greater than the intensity of the second mixing operation, it is necessary to control that the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation are greater than the intensity of the second mixing step in the second mixing operation.

[0205] Preferably, taking the number of aspirations and expulsions in the first mixing step and the number of bubble expulsions in the second mixing step as an example, when the number of aspirations and expulsions in the first mixing step is equal to the number of bubble expulsions in the second mixing step, the intensity of the first mixing step is equal to the intensity of the second mixing step. Therefore, the intensity of the first mixing step and the intensity of the second mixing step in the first mixing operation are greater than the intensity of the second mixing step in the second mixing operation, including but not limited to the following operational examples:

[0206] The first operational example is to control the number of times the second mixing step in the first mixing operation is vented (10 times) to be greater than the number of times the second mixing step in the second mixing operation is vented (8 times).

[0207] The second operational example is to control the number of times (10 times) the first mixing step in the second mixing operation to be equal to the number of times (10 times) the second mixing step in the second mixing operation.

[0208] The third operational example is to control the number of times the second mixing step in the first mixing operation exhales (6 times) to be less than the number of times the second mixing step in the second mixing operation exhales (8 times), and then control the number of times the first mixing step in the first mixing operation exhales (6 times) to be greater than the difference between the number of times the first mixing step in the second mixing operation exhales (8 times - 6 times = 2 times).

[0209] Thirdly, see Figure 3 As shown, Figure 3This is a schematic diagram of another optional sample analyzer provided in an embodiment of this application. The sample analyzer 300 includes a sample injection device 301, an information acquisition device 302, a mixing device 303, a detection device 304, and a control device 305. The sample injection device 301 is used to load or store the sample, the information acquisition device 302 is used to acquire sample information, the mixing device 303 is used to mix the sample, the detection device 304 is used to detect the mixed sample, and the control device 305 is communicatively connected to the sample injection device 301, the information acquisition device 302, the mixing device 303, and the detection device 304.

[0210] In some alternative embodiments, the sample introduction device 301 may be a test tube tray containing one or more hollow tubes, each hollow tube loading or storing samples from different test subjects, and then the mixing device 303 mixing the samples in each hollow tube.

[0211] The control device 305 is used to determine the color parameters of the sample based on the sample information, and to determine the mixing working parameters of the mixing device 303 based on the color parameters, and to control the mixing device 303 to mix the sample based on the mixing working parameters.

[0212] In some alternative embodiments, the mixing device 303 includes a sampling assembly for mixing the sample, then aspirating at least a portion of the mixed sample and delivering it to the detection device 304 for detection.

[0213] The sampling component can be a sample needle, which is directly inserted into the hollow tube. Then, a certain amount of sample liquid is drawn from the mixed sample using the principle of negative pressure. The sample needle is then removed from the hollow tube and transferred to the detection device 304. Finally, the sample liquid in the sample needle is delivered to the detection device 304 for detection using the principle of positive pressure.

[0214] Furthermore, the sampling assembly can also be a sampling pump or a pipette, and its sampling principle is similar to that of the sample needle mentioned above, which will not be elaborated further in this application.

[0215] It should be noted that the sample aspiration assembly can also perform at least one of the following mixing operations on the sample liquid: aspirating a certain amount of sample liquid and regurgitating it to mix the sample, expelling air bubbles into the sample to mix the sample by expelling air bubbles, or moving back and forth in the sample to stir and mix the sample.

[0216] In some alternative embodiments, the mixing device 303 further includes a shaking component for shaking the sample to achieve mixing.

[0217] Preferably, the rocking assembly is equipped with a motor or pneumatic device to provide a stable rocking power source, and the rocking assembly is also equipped with a connecting rod, eccentric wheel or ball bearing slide to convert the rotation or linear motion of the power unit into a specific rocking mode (such as horizontal rocking, circular rocking, linear rocking or pulse rocking).

[0218] Furthermore, the mixing parameters include the shaking frequency, shaking duration, shaking angle, shaking direction, and shaking intensity of the shaking component; the aspiration volume, aspiration frequency, and aspiration duration of the sampling component; the gas volume and flow rate of the aspiration bubbles; the aspiration duration and frequency of the aspiration bubbles; the stirring duration, stirring frequency, and stirring direction of the sampling component.

[0219] It should be noted that the sample is a liquid sample, and the sample information includes the color of the sample, so the control device 305 can determine the color parameters of the sample based on the sample information.

[0220] The sample can be a urine sample, a blood sample, a prostatic fluid sample, a tissue fluid sample, or a saliva sample. This application does not make any specific limitations. Preferred, the sample provided in the embodiments of this application is a urine sample. When the sample is a urine sample, the color parameter of the sample is the same as the color parameter of the urine sample.

[0221] In some optional embodiments, the control device 305 controls the mixing device 303 to mix the sample according to the mixing working parameters, which can be divided into multiple mixing intensity levels. For example, when the color parameter is in a preset first threshold range, the mixing working parameters of the mixing device 303 at the first mixing intensity level are determined, and then the mixing device 303 is controlled to mix the sample according to the mixing working parameters; when the color parameter is in a preset second threshold range, the mixing working parameters of the mixing device 303 at the second mixing intensity level are determined, and then the mixing device 303 is controlled to mix the sample according to the mixing working parameters; when the color parameter is in a preset third threshold range, the mixing working parameters of the mixing device 303 at the third mixing intensity level are determined, and then the mixing device 303 is controlled to mix the sample according to the mixing working parameters.

[0222] Among them, the intensity of the first mixing level is greater than that of the second mixing level, the intensity of the second mixing level is greater than that of the third mixing level, the color parameter changes from the first threshold interval to the second threshold interval from light yellow to dark yellow, and the color parameter changes from the second threshold interval to the third threshold interval from dark yellow to reddish brown.

[0223] In summary, this application, by incorporating a sample introduction device 301, an information acquisition device 302, a mixing device 303, a detection device 304, and a control device 305, can automatically identify high-value samples based on their color parameters and adjust the mixing intensity to improve the accuracy and efficiency of the detection results.

[0224] Fourthly, see Figure 4 As shown, Figure 4 The flowchart illustrates a mixing control method provided in this application embodiment. This mixing control method is applied to a sample analyzer as described in the first aspect above. The sample analyzer includes a sample injection device, an information acquisition device, a mixing device, a detection device, and a control device. The control device is communicatively connected to the sample injection device, the information acquisition device, the mixing device, and the detection device, respectively. The mixing control method includes, but is not limited to, steps S401 to S402.

[0225] Step S401: Identify the sample information of the sample through the information acquisition device.

[0226] Step S402: Determine the physical characteristics of the sample based on the sample information, and make a judgment based on the physical characteristics. If the physical characteristics meet the first preset condition, control the mixing device to perform the first mixing operation on the sample. If the physical characteristics meet the second preset condition, control the mixing device to perform the second mixing operation on the sample.

[0227] The intensity of the first mixing operation is greater than that of the second mixing operation.

[0228] The above-mentioned mixing control method identifies sample information through an information acquisition device, then determines the physical characteristics of the sample based on the sample information, and makes a judgment based on the physical characteristics. If the physical characteristics meet a first preset condition, the mixing device is controlled to perform a first mixing operation on the sample; if the physical characteristics meet a second preset condition, the mixing device is controlled to perform a second mixing operation on the sample. The intensity of the first mixing operation is greater than that of the second mixing operation, thereby automatically identifying high-value samples based on the physical characteristics of the sample and adjusting the mixing intensity to improve the accuracy and efficiency of the detection results.

[0229] Fifthly, see Figure 5 As shown, Figure 5 The flowchart illustrates another mixing control method provided in this application embodiment. This mixing control method is applied to a sample analyzer as described in the second aspect above. The sample analyzer includes a sample injection device, an information acquisition device, a mixing device, a detection device, and a control device. The control device is communicatively connected to the sample injection device, the information acquisition device, the mixing device, and the detection device, respectively. The mixing control method includes, but is not limited to, steps S501 to S502.

[0230] Step S501: Obtain sample information of the sample through the information acquisition device;

[0231] Step S502: If the sample information meets the first preset condition, control the mixing device to perform the first mixing operation on the sample; if the sample information meets the second preset condition, control the mixing device to perform the second mixing operation on the sample.

[0232] The intensity of the first mixing operation is greater than that of the second mixing operation.

[0233] The above-mentioned mixing control method acquires sample information through an information acquisition device. Then, if the sample information meets a first preset condition, the mixing device is controlled to perform a first mixing operation on the sample. If the sample information meets a second preset condition, the mixing device is controlled to perform a second mixing operation on the sample. The intensity of the first mixing operation is greater than that of the second mixing operation. This allows for the automatic identification of high-value samples based on the sample information and adjustment of the mixing intensity to improve the accuracy and efficiency of the detection results.

[0234] Sixth aspect, see Figure 6 As shown, Figure 6 The flowchart illustrates a mixing control method provided in this application embodiment. This mixing control method is applied to a sample analyzer as described in the third aspect above. The sample analyzer includes a sample injection device, an information acquisition device, a mixing device, a detection device, and a control device. The control device is communicatively connected to the sample injection device, the information acquisition device, the mixing device, and the detection device. The mixing control method includes, but is not limited to, steps S601 to S603.

[0235] Step S601: Identify the sample information of the sample through the information acquisition device.

[0236] Step S602: Determine the color parameters of the sample based on the sample information.

[0237] Step S603: Determine the physical characteristics of the sample based on the sample information, and make a judgment based on the physical characteristics. If the physical characteristics meet the first preset condition, control the mixing device to perform the first mixing operation on the sample. If the physical characteristics meet the second preset condition, control the mixing device to perform the second mixing operation on the sample.

[0238] The intensity of the first mixing operation is greater than that of the second mixing operation.

[0239] The above-mentioned mixing control method identifies sample information through an information acquisition device, then determines the sample color parameters based on the sample information, and finally determines the mixing operating parameters of the mixing device based on the color parameters. The mixing device is then controlled to mix the sample based on the mixing operating parameters. This allows for the automatic identification of high-value samples based on the sample color parameters and adjustment of the mixing intensity to improve the accuracy and efficiency of the detection results.
