Description

TECHNICAL FIELD

[0001] The present application relates to the field of sample analysis, and in particular to a sample analyzer, a sample analysis method and a computer readable storage medium for implementing the method. BACKGROUND

[0002] Sample analyzers, such as blood analyzers, are commonly used in clinical diagnosis processes to determine samples of blood, urine, body fluid (ascites, cerebrospinal fluid, pleural fluid, etc.) collected from patients. Taking blood samples as an example, there are two ways to collect blood at present: collecting venous blood (macro sample) and collecting capillary blood (micro sample). The amount of venous blood collected is relatively large (≥1 mL), which is usually suitable for adult patients; while it is sometimes difficult to collect blood through the venous method for infants, children or critically ill patients, in which case capillary blood is often collected. The amount of capillary blood that can be collected is relatively small (mostly ≤100 μL).

[0003] Due to the difference in blood volume between macro samples (venous blood) and micro samples (capillary blood), the containers used to hold macro samples and the containers used to hold micro samples are also different. The existing sample analyzers have different processing methods for macro samples and micro samples. In order to identify different containers, different sample holders are usually used to distinguish between the two types of sample containers. However, this scheme of distinguishing between the placement of venous blood sample containers and capillary blood sample containers by different sample holders has certain limitations. If the wrong sample holder is used, the capillary blood sample container or the sampling needle of the sample analyzer may be damaged. SUMMARY

[0004] The present application provides a sample analyzer with a universal sample holder, as well as a corresponding sample analysis method and a computer readable storage medium.

[0005] The first aspect of the present application relates to a sample analyzer, comprising:

[0006] A conveying device is used to convey a sample holder in which a micro sample container and a macro sample container can be mixedly placed, the sample holder is provided with a plurality of fixing holes, wherein the micro sample container can hold less sample than the macro sample container, the micro sample container is fixed in the fixing hole on the sample holder by a fixing member, and the fixing member is provided with an identification part indicating that the sample container is a micro sample container or the sample carried by the sample container is a micro sample;

[0007] An identification reading device is used to identify the identification part on the fixing member;

[0008] A sample processing device is used to process the sample in the sample container;

[0009] A control device is electrically connected to the above-mentioned devices and is configured to:

[0010] When the identification reading device detects the identification portion of the fixing member, the sample processing device is controlled to process the sample according to a first sample processing condition; when the identification reading device does not detect the identification portion of the fixing member, the sample processing device is controlled to process the sample according to a second sample processing condition different from the first sample processing condition.

[0011] A second aspect of the present invention relates to a sample analysis method, comprising the following steps:

[0012] Using an identification reading device, a sample container on a sample rack capable of holding a mixture of micro-sample containers and macro-sample containers is identified, wherein the micro-sample container can hold fewer samples than the macro-sample container, and the micro-sample container is fixed in a fixing hole of the sample rack by a fixing member, wherein the fixing member is provided with an identification portion indicating that the sample container is a micro-sample container or that the sample carried by the sample container is a micro-sample;

[0013] When the identification reading device detects the identification portion of the fixing member, the sample processing device is controlled to process the sample according to the first sample processing condition.

[0014] When the identification reading device does not detect the identification portion of the fixing member, the sample processing device is controlled to process the sample according to a second sample processing condition different from the first sample processing condition.

[0015] A third aspect of the present invention further relates to a computer-readable storage medium storing executable instructions, configured to cause a processor to execute the executable instructions to implement the above-mentioned sample analysis method.

[0016] The present invention utilizes a fixture provided with an identification portion indicating that the sample container type is a micro-sample container, and determines whether the sample container placed in the sample rack is a micro-sample container or a constant-sample container by detecting the identification portion of the fixture by an identification reading device. Based on the determination result, a first sample processing condition is then used to process the sample in the micro-sample container, or a second sample processing condition different from the first sample processing condition is used to process the sample in the constant-sample container. The present invention solves the problem of determining the sample type when micro-sample containers and constant-sample containers are mixed on a sample rack, thereby eliminating the need for users to distinguish and place different types of sample containers on different sample racks, thereby facilitating user operation.

[0036] See also Figure 1 、 Figure 2a and Figure 2b The illustrated embodiment of the present invention provides a sample analyzer 1 comprising a sample processing device 2, a transport device 3 disposed on one side of the sample processing device 2 along the Y1 direction, an identification reader 24, and a control device (not shown). The transport device 3 is used to transport a sample rack 80 so that the sample processing device 2 can process samples in sample containers placed on the sample rack 80. The control device is electrically connected to the sample processing device 2, the transport device 3, and the identification reader 24 and is configured to execute a sample analysis method, described in detail below.

[0037] It is understood that the sample rack 80 can be used to place micro sample containers 91 (such as Figure 6 and Figure 7 as shown) or a constant sample container 90 (as shown Figure 4and Figure 5 or both are placed mixedly.

[0038] The sample processing device 2 can comprise a first mixing device 21, a second mixing device 22 and a sampling device 23. The sample processing device 2 can further comprise a reaction device and a measuring device, which are not shown in the figure. The first mixing device 21 and the second mixing device 22 are respectively used for mixing the sample in the sample container. The sampling device 23 is used for sampling the mixed sample. The identification reading device 24 is used for identifying the type of the sample container.

[0039] Please refer to Figure 3 The sample rack 80 is arranged with a plurality of fixing holes 801 in a single direction, and each fixing hole 801 is used for placing a micro sample container 91 or a constant sample container 90. Each fixing hole 801 is also provided with an opening 802, so that the identification reading device 24 can identify the type of the sample container or the sample carried by the sample container through the opening 802. It can be understood that in other embodiments, the opening 802 corresponding to the fixing hole 801 can also be provided with a hollow structure, transparent material or other effective solutions to expose the sample container, so as to facilitate the identification of the sample container by the identification reading device 24. When the sample rack 80 is placed on the conveying device 3, the sample rack 80 is preferably placed along the X1 direction, so that the fixing holes 801 on the sample rack 80 are arranged along the X1 direction, and the micro sample containers 91 and the constant sample containers 90 fixed in the fixing holes 801 pass through the sample processing device 2 in sequence for processing.

[0040] Figure 2c The internal structure of the conveying device 3 is shown. The conveying device 3 comprises a sample rack support part 31, a sample rack feeding device 32, a sample rack transverse conveying device 33 and a sample rack discharging device 34. The sample rack support part 31 comprises a pre-analysis sample rack storage area 311 which can place a plurality of sample racks 80 fixed with sample containers containing pre-analysis samples, a post-analysis sample rack storage area 312 which can place a plurality of sample racks 80 fixed with sample containers containing post-analysis samples, and a sample analysis area 313 located between the pre-analysis sample rack storage area 311 and the post-analysis sample rack storage area 312 and close to the sample processing device 2. A sample rack feeding turning area 311a is provided on the side of the pre-analysis sample rack storage area 311 close to the sample analysis area 313, and a sample rack discharging turning area 312a is provided on the side of the post-analysis sample rack storage area 312 close to the sample analysis area 313. The sample rack feeding device 32 can convey the sample rack 80 to the sample rack feeding turning area 311a along the Y2 direction, the sample rack transverse conveying device 33 can convey the sample rack 80 on the sample analysis area 313 along the X1 direction, and the sample rack discharging device 34 can convey the sample rack 80 out of the sample rack discharging turning area 312a along the Y1 direction.

[0041] Figure 2d is a schematic diagram of the functional position arrangement of the sample analyzer 1, including a code scanning position 201, a mixing position 202, and a sampling position 203. Figure 2d The functional position arrangement shown only illustrates that the sample analyzer 1 has the code scanning position 201, the mixing position 202, and the sampling position 203, and does not limit the relative relationship of the above positions (for example, it does not limit that the code scanning position 201 and the mixing position 202 are separated by 1 position, nor does it limit that the mixing position 202 and the sampling position 203 are adjacent).

[0042] When the automatic sampling measurement is started, the sample rack feeding device 32 first pushes the sample racks 80 stored in the pre-analysis sample rack storage area 311 along the Y2 direction one by one to the sample rack feeding turning area 311a. The sample racks 80 entering the sample rack feeding turning area 311a will be continuously transported along the X1 direction by the sample rack transverse transport device 33. The sample containers containing samples entering the analysis area 313 will be transported to the code scanning position 201 of the sample analyzer 1 for code scanning, then to the mixing position 202 for mixing, and then to the sampling position 203 for sampling. When the sample rack 80 fixed with the sample container containing the sample is transported to the sample rack feeding turning area 312a by the sample rack transverse transport device 33, the sample rack feeding device 34 pushes the sample rack 80 to the post-analysis sample rack storage area 312.

[0043] Figure 4 and Figure 5 A constant sample container 90 related to the present application is shown. The constant sample container 90 comprises a first tube body 901 and a first tube cap 902. The first tube body 901 is provided with an inner cavity for receiving a venous blood sample, and the amount of the sample received is usually ≥1 mL. The inner cavity of the first tube body 901 is open at the top, and the first bottom 901a of the inner cavity is located at the lowermost part of the first tube body 901. The first tube cap 902 is used to seal the top opening of the inner cavity of the first tube body 901, so as to seal the venous blood sample in the inner cavity of the first tube body 901. The middle region 902a of the first tube cap 902 is a puncture area, and the sampling needle 231 (as shown) of the sampling device 23 can pierce the middle region 902a to draw the sample into the inner cavity of the first tube body 901. The outer diameter of the first tube body 901 is slightly smaller than the hole diameter of the fixing hole 801 of the sample rack 80, so that the constant sample container 90 can be placed in the fixing hole 801 of the sample rack 80. The tube body of the first tube body 901 is relatively long, and a bar code label 903 can be attached to the tube body of the first tube body 901. Figure 14 The sampling needle 231 of the sampling device 23 can pierce the middle region 902a to draw the sample into the inner cavity of the first tube body 901.

[0044] Figure 6 and Figure 7A micro-sample container 91 is shown. The micro-sample container 91 is usually used to hold a blood sample. The micro-sample container 91 comprises a second tube 911 and a second cap 912. The second tube 911 is provided with an inner cavity for holding a micro-sample. The volume of the sample held in the inner cavity is usually ≤ 250uL, and often ≤ 80uL. The inner cavity of the second tube 911 is open at the top, and the second bottom 911a of the inner cavity is at a distance from the lowermost part of the second tube 911. The second cap 912 is used to seal the top opening of the inner cavity of the second tube 911, so as to seal the micro-sample in the inner cavity of the second tube 911. The second cap 912 is usually made of plastic, and is usually removed when the sample in the micro-sample container 91 is to be tested. In order to ensure that the liquid level of the blood sample in the inner cavity meets the sampling requirements of the sampling needle 231, the outer diameter of the second tube 911 of the micro-sample container 91 is usually smaller than the outer diameter of the first tube 901 of the macro-sample container 90, and the length (or the length of the inner cavity) of the micro-sample container 91 is also smaller than the length (or the length of the inner cavity) of the venous sample container 90. Therefore, the micro-sample container 91 cannot be directly placed in the fixed hole 801 of the sample rack 80 as the macro-sample container 90.

[0045] For this purpose, see Figures 8a to 8d The present application also relates to a fixing member 85 for holding the micro-sample container 91. The fixing member 85 is internally provided with a fixing cavity 851 for accommodating the micro-sample container 91. The hole diameter of the fixing cavity 851 is slightly larger than the outer diameter of the tube 911 of the micro-sample container 91, so that the micro-sample container 91 can be fixedly placed in the fixing cavity 851. The outer diameter of the fixing member 85 corresponds to the hole diameter of the fixed hole 801 of the sample rack 80, i.e. the outer diameter of the fixing member 85 is slightly smaller than the hole diameter of the fixed hole 801 of the sample rack 80, so that the fixing member 85 can be placed in the fixed hole 801 of the sample rack 80. Therefore, after the micro-sample container 91 is placed in the fixing cavity 851, the fixing member 85 can be placed in the fixed hole 801 of the sample rack 80. Meanwhile, the fixing member 85 is also provided with an identification part 852 indicating that the sample container is a micro-sample container. When the fixing member 85 holding the micro-sample container 91 is placed on the sample rack 80, the identification reading device 24 can identify the identification part 852 through the opening 802 of the fixed hole 801, so as to determine whether the sample container currently analyzed by the sample analyzer 1 is a micro-sample container 91.

[0046] It can be understood that, because the shapes of the macro-sample container 90 and the micro-sample container 91 are different, and the sample volumes are also different, the processing methods required by the sample analyzer 1 of the present application when analyzing and testing the macro-sample and the micro-sample will also be different. For example, Figure 9As shown, through the above arrangement, the sample rack 80 can simultaneously accommodate both micro-sample containers 91 and constant-sample containers 90, and the order in which the micro-sample containers 91 and constant-sample containers 90 are placed can be arbitrary, i.e., both can be mixed and placed in the sample rack 80. Because the fixing member 85 for attaching the micro-sample container 91 to the fixing hole 801 is provided with an identification portion 852, the sample analyzer 1 of the present invention can read the identification portion 852 via the identification reading device 24 and process the sample in the micro-sample container 91 according to the first sample processing condition of the sample processing device 2 for the sample container in which the identification portion 852 is read. If the identification reading device 24 does not recognize the identification portion 852, it can be determined that the sample container currently being analyzed and tested is a constant-sample container 90. Subsequently, under the control of the control device, the sample processing device 2 processes the sample in the constant-sample container 90 according to a second sample processing condition different from the first sample processing condition.

[0047] Therefore, by providing the fixing member 85, the micro sample container 91 and the normal sample container 90 can be mixed and placed on the sample rack 80, and the identification portion 852 provided on the fixing member 85 is further used to distinguish the micro sample container from the normal sample container. Then, the sample processing device 2 adopts two different sample processing conditions to process the samples in the micro sample container and the normal sample container respectively, which can effectively avoid the defect that the sample analyzer 1 cannot recognize the micro sample container 91 and the normal sample container 90 due to the mixed placement, which may damage the micro blood sample container 91 or the sampling needle 231 of the sampling device 23.

[0048] Understandably, in Figure 2b In the embodiment, the sample processing device 2 may further include a test tube pressing device 25 and a test tube rotating device 26. The test tube pressing device 25 and the test tube rotating device 26 cooperate to rotate the fixing member 85 of the constant sample container 90 or the micro sample container 91 fixed on the sample rack 80, so that the side of the fixing member 85 of the constant sample container 90 or the micro sample container 91 with the barcode label 903 is turned to the identification reading device 24. Of course, the sample processing device 2 may not include the test tube pressing device 25 and the test tube rotating device 26, and the identification portion 852 attached to the side wall of the fixing member 85 may be arranged in accordance with the Figure 8b The entire peripheral area of ​​the fixing member 85 is pasted as shown, ensuring that the identification reading device 24 can reliably obtain special information, such as special coding information, of the identification portion 852 pasted on the side wall of the fixing member 85.

[0049] In some embodiments, see Figure 2dWhen each fixing hole 801 of the sample rack 80 passes the code scanning position 201, the identification reading device 24 reads the coding information of the identification portion 852 of the fixing member 85 containing the micro sample container 91 or the barcode label 903 of the large sample container 90 located at that position through the opening 802 of the sample rack 80. The coding rules of the identification portion 852 of the fixing member 85 can be different from the coding rules of the barcode label 903 of the large sample container 90. For example, the coding of the barcode label 903 of the large sample container 90 is a pure numeric sequence, while the coding of the identification portion 852 of the fixing member 85 of the micro sample container 91 can include letters or special characters, thereby distinguishing between the large sample container 90 and the micro sample container 91.

[0050] In some embodiments, the identification portion 852 on the fixture 85 includes micro-sample container type information and fixture identity information. Before controlling the transport device 3 to transport the sample rack 80 containing a mixture of normal sample containers 90 and micro-sample containers 91, and in particular before placing the micro-sample container 91 on the sample rack 80 via the fixture 85, the control device first receives the identity information of the micro-sample container 91 to be placed on the sample rack 80 and the identity information of the fixture 85 used to secure the micro-sample container 91 to the sample rack 80, thereby establishing a one-to-one correspondence between the identity information of the micro-sample container 91 and the identity information of the corresponding fixture 85. It is understood that when there are multiple micro-sample containers 91 on the sample rack 80, the control device receives the identity information of each micro-sample container 91 and the identity information of the fixture 85 corresponding to each micro-sample container 91, and establishes a correspondence between each micro-sample container 91 and its corresponding fixture 85. Therefore, when the control device controls the transport device 3 to transport the sample rack 80 through the barcode scanning position 201, if the identification portion 852 is detected by the identification reading device 24, the sample type information and identity information of the corresponding micro-sample container 91 are obtained based on the information contained in the identification portion 852 and the association relationship. This is particularly applicable to scenarios where the fixing member 85 is reusable, that is, the fixing member 85 can carry disposable micro-sample containers containing different patient samples at different times, and the micro-sample container itself is provided with identity information indicating the patient's identity. In particular, if the user affixes a barcode indicating the patient's identity to the micro-sample container, in this case, the barcode of the micro-sample container cannot be recognized because it is placed on the sample rack via the fixing member. Therefore, before the micro-sample container is placed on the sample rack, the identity information of the micro-sample container needs to be associated with the identity information of the fixing member 85 that fixes the micro-sample container. Furthermore, after the detection is completed, the association relationship is released so that the fixing member 85 can be reused.

[0051] Because of the difference in capacity between the micro sample and the constant sample, if the mixing is performed in the same mixing manner, it is easy to cause the mixing effect of the micro sample or the constant sample to be unsatisfactory. Therefore, in one embodiment, the sample processing device 2 includes only one mixing device, which can mix the micro sample container 91 and the constant sample container 90 using different mixing conditions, that is, the first sample processing condition includes using the mixing device to mix the sample in the micro sample container with a first mixing condition, and the second sample processing condition includes using the mixing device to mix the sample in the constant sample container with a second mixing condition different from the first mixing condition. Different mixing conditions can, for example, include different mixing times, different mixing times, etc. Alternatively, the sample processing device 2 includes a first mixing device 21 and a second mixing device 22 that are different from each other. When processing the sample according to the first sample processing condition, the control device drives the first mixing device 21 to mix the sample in the micro sample container 91; when processing the sample according to the second sample processing condition, the control device drives the second mixing device 22 to mix the sample in the constant sample 90.

[0052] For example, when each fixing hole 801 of the sample rack 80 passes through the code scanning position 201, the information read by the identification reading device 24, such as the code scanner, is consistent with the identification part 852 of the fixing part 85, such as the special information of the barcode label, such as the coding rule, when the sample container placed in the fixing hole 801 reaches the mixing position 202, the first mixing device 21 is used to mix the sample; conversely, when the information read by the identification reading device 24 does not meet the special information of the identification part 852 of the fixing part 85, such as the coding rule, or the identification reading device 24 does not read the special information, such as the coding information, when the sample container placed in the fixing hole 801 reaches the mixing position 202, the second mixing device 22 is used to mix the sample.

[0053] For details, please see Figure 10 In one embodiment, the first mixing device 21 includes a bracket 211, a fixing base 212, a motor 213, and a sensor 214. The bracket 211 is used to fix the motor 213 and the sensor 214. The motor 213 serves as a power source and can drive the fixing base 212 to rotate clockwise or counterclockwise around its own axis after receiving instructions from the control device. The sensor 214 is used to detect whether the fixing base 212 is rotating and to detect the rotation speed of the fixing base 212. The fixing base 212 is rotatably connected to the motor 213. The fixing base 212 can be directly fixed to the rotating shaft of the motor 213, and the motor 213 can be a stepping motor. A accommodating chamber 2121 is provided at the top of the fixing base 212. The accommodating chamber 2121 is used to accommodate the micro-sample container 91. It will be understood that the motor 213 drives the fixing base 212 to rotate, which can drive the fixing base 212 and the micro-sample container 91 in its accommodating chamber 2121 to rotate together.

[0054] Because the micro sample container 91 is connected to the fixing hole 801 of the sample rack 80 through the fixing member 85, in some embodiments, such as Figure 11 As shown, the micro-sample container 91 is placed in the first mixing device 21 along with its fixing member 85. When the motor 213 of the first mixing device 21 drives the fixing seat 212 to rotate the fixing member 85, the micro-blood sample container 91 contained in the fixing member 85 rotates synchronously, achieving the effect of the first mixing device 21 mixing the sample in the micro-sample container 91.

[0055] For further information, see Figure 12 The bottom of the accommodating cavity 2121 in the fixing seat 212 can be provided with an abutment portion, so that the fixing member 85 communicates with the micro-sample container 91 contained therein and can be placed obliquely in the accommodating cavity 2121. When the motor 213 drives the fixing seat 212 to rotate the obliquely placed micro-sample container 91, the sample rises while rotating along the inner wall of the accommodating cavity of the micro-sample container 91 under the action of centrifugal force; when the fixing seat 212 stops rotating, the sample that previously climbed onto the side wall of the accommodating cavity of the micro-blood sample container 91 flows back to the bottom of the micro-blood sample container 91. The first mixing device 21 achieves better mixing of the sample in the micro-sample container 91 by driving the sample's rotational motion as well as the sample's climbing and reflux motions.

[0056] See Figure 13 The second mixing device 22 for mixing the sample in the constant sample container 90 is constructed as a mixing clamping claw structure. For example, driven by the three driving sources of the second mixing device 22, the clamping claw 221 of the second mixing device 22 can realize linear motion along the Y1 or Y2, Z1 or Z2 directions, and can also swing around the axis of the clamping claw 221 in the R1 or R2 direction. When it is necessary to mix the sample in the constant sample container 90 on the sample rack 80, the clamping claw 221 of the second mixing device 22 clamps the constant sample container 90 from the fixing hole 801 of the sample rack 80 and drives the constant sample container 90 to swing, thereby mixing the sample in the constant sample container 90.

[0057] In some embodiments, the second mixing device 22 can function as a transport device for transferring the fixture 85 and the micro-sample container 91 placed therein to the first mixing device 21. Specifically, the control device is further configured to, when controlling the sample processing device 2 to process a sample according to the first sample processing conditions, drive the second mixing device 22 to transfer the fixture 85 and the micro-sample container 91 placed therein to the first mixing device 21 to mix the sample in the micro-sample container 91. When the sample in the micro-sample container 91 on the sample rack 80 needs to be mixed, the second mixing device 22 removes the fixture 85 and the micro-sample container 91 from the fixing hole 801 of the sample rack 80 and places them into the sample container accommodating cavity 2121 of the first mixing device 21. The motor 213 of the first mixing device 21 then drives the sample container holder 212 to rotate, thereby mixing the sample in the micro-sample container 91. Therefore, it is not necessary to configure a special robotic arm for the first mixing device 21 to transport the micro sample container 91 , thereby simplifying the internal structure of the sample analyzer 1 of the present invention.

[0058] Of course, in an alternative embodiment, a transport device independent of the second mixing device 22 can also be provided to clamp the fixing member 85 and the micro sample container 91 out of the fixing hole 801 of the sample rack 80 and place them into the sample container accommodating cavity 2121 of the first mixing device 21.

[0059] The difference between the first sample processing condition and the second sample processing condition is not only reflected in the different mixing methods, but also in the sampling process.

[0060] Please see the attached Figure 14 The sampling device 23 includes a sampling needle 231 and a lifting motor 233 that drives the sampling needle 231 to move vertically. The sampling needle 231 can move along the Z1 and Z2 directions (usually the vertical direction) under the drive of the lifting motor 233. In addition, the sampling device 23 also includes a shift motor 232 that drives the sampling needle 231 to move horizontally. The sampling needle 231 can move along the Y1 and Y2 directions under the drive of the shift motor 232. The shift motor 232 and the lifting motor 233 are preferably stepping motors. The shift motor 232 and the lifting motor 233 are also electrically connected to the control device at the same time, and receive instructions from the control device to drive the sampling needle 231 to move. The sampling device 23 also includes a power device (not shown) that drives the sampling needle to absorb the sample, such as a quantitative pump.

[0061] The conveying device 3 conveys the sample rack 80 along the X1 direction, and sends the sample containers on the sample rack 80 to the sampling sites 203 of the corresponding sampling needles 231 one by one for sampling. During the sampling process, the lifting motor 233 drives the sampling needle 231 to move downward to the bottom of the cavity of the sample container at the sampling site 203, so that the sampling needle 231 can suck the sample from the sample container. Of course, the sampling needle 231 can also be driven by the shifting motor 232 to move above the sampling site 203, and then the sampling needle 231 is driven by the lifting motor 233 to move downward to achieve the sampling operation on the sample container at the sampling site 203.

[0062] As shown in Figure 15 It can be seen that when the trace sample containers 91 and the constant sample containers 90 are mixed and placed in the same sample rack 80, the bottom heights of the cavities of the trace sample containers 91 and the constant sample containers 90 are quite different. This is because the constant sample containers 90 are directly placed in the sample rack 80, so that the bottom of the cavity of the constant sample container 90 is close to the bottom of the sample rack 80, while the trace sample containers 91 are placed in the sample rack 80 through the fixing member 85, so that the bottom of the cavity of the trace sample container 91 is lifted. If the sampling needle 231 only moves downward to the bottom height of the cavity of the trace sample container 91, the sampling needle 231 can not be able to suck the sample in the constant sample container 90; if the sampling needle 231 moves downward to a height at which the sample in the constant sample container 90 can be sucked, the sampling needle 231 will damage the trace sample container 91. That is, the sampling needle 231 of the sampling device 23 has different descending heights when entering the trace sample container 91 and the venous blood sample container 90 to suck the sample. When the sampling needle 231 samples the trace sample container 91, the sampling needle 231 needs to descend from the initial A height position to the first height position (C height position in the figure); when the sampling needle 231 samples the constant sample container 90, the sampling needle 231 needs to descend from the initial A height position to the second height position (D height position in the figure).

[0063] Therefore, in one embodiment, in order to enable the sampling needle 231 of the sampling device 23 to simultaneously aspirate samples from the micro sample container 91 and the constant sample container 90 without damaging the sample containers, it is necessary to control the descending height of the sampling needle 231 of the sampling device 23 according to different sample container types. Therefore, when the control device controls the sample processing device 2 to process the sample according to the first sample processing condition, that is, when the sampling needle 231 extracts the sample from the micro sample container 91, the control device controls the sampling needle 231 to move down to the first height (C), ensuring that the needle tip of the sampling needle 231 is close to the bottom of the cavity of the micro sample container 91, thereby realizing the sampling operation. When the control device controls the sample processing device 2 to process the sample according to the second sample processing condition, that is, when the sampling needle 231 extracts the sample from the constant sample container 90, the control device controls the sampling needle 231 to move down to a second height (D) different from the first height, ensuring that the needle tip of the sampling needle 231 is close to the bottom of the cavity of the constant sample container 90, thereby realizing the sampling operation. Figure 15 In the illustration, the second height is lower than the first height.

[0064] For example, when each fixed hole 801 of the sample rack 80 passes through the code scanning position 201, the information read by the identification reading device 24, such as the code scanner, is consistent with the identification part 852 of the fixing part 85, such as the special information of the barcode label, such as the coding rule, when the sample container placed in the fixed hole 801 reaches the sampling position 203, the control device controls the sampling needle 231 to move down to the first height to aspirate the sample in the sample container; conversely, when the information read by the identification reading device 24 does not conform to the special information of the identification part 852 of the fixing part 85, such as the coding rule, or the identification reading device 24 does not read the special information, such as the coding information, when the sample container placed in the fixed hole 801 reaches the sampling position 203, the control device controls the sampling needle 231 to move down to the second height lower than the first height to aspirate the sample in the sample container.

[0065] It should be noted that the first height is variable because the microsample container 91 includes at least a first microsample container and a second microsample container, each of which differs in capacity or the type of sample carried. When placed on the same sample rack, the bottom of the cavity of each microsample container is at different distances from the bottom of the sample rack. Therefore, the first height needs to be adjusted according to the height of the bottom of the cavity of the microsample container 91. In addition, the sample liquid level heights of the first microsample container and the second microsample container may also differ due to the different capacities. If the control device drives the sampling needle 231 to match the first height of the first microsample container to extract the sample from the second microsample container, there may be a risk that the sampling needle 231 will not be able to absorb the sample in the second microsample container or will damage the second microsample container.

[0066] As mentioned above, the identification reading device 24 can extract the type information of the micro-sample container 91 by identifying the identification portion 852 of the fixture 85. In addition, by identifying the identity information of the fixture 85, the control device can also find the identity information of the micro-sample container 91 carried by the fixture 85. Therefore, in one embodiment, corresponding to the scenario where the micro-sample container 91 includes a first micro-sample container and a second micro-sample container, the first height information corresponding to the micro-sample container 91 can be associated with the identification portion 852 of the fixture 85 and / or the identity information of the micro-sample container 91. Furthermore, when the identification portion 852 detected by the identification reading device 24 indicates that the micro-sample container 91 is a first micro-sample container, the control device controls the sampling needle 231 to move down to a first height corresponding to the first micro-sample container, and then samples the first micro-sample container; when the identification portion 852 detected by the identification reading device 24 indicates that the micro-sample container 91 is a second micro-sample container, the control device controls the sampling needle 231 to move down to the first height corresponding to the second micro-sample container, and then samples the second micro-sample container.

[0067] Of course, the micro-sample container 91 corresponding to the sample analyzer 1 of the present invention may have two or more sample types, and the two or more sample types may be respectively set with their own matching first height information.

[0068] Furthermore, the difference between the first sample processing condition and the second sample processing condition is also reflected in the sampling volume and reaction conditions. For example, when the identifier reading device 24 detects the identifier portion 852, the control device controls the sampling needle 231 to aspirate a first amount of sample from the micro-sample container. When the identifier reading device 24 does not detect the identifier portion 852, the control device controls the sampling needle 231 to aspirate a second amount of sample from the constant-volume sample container, where the second amount is greater than the first amount.

[0069] For another example, the sample analyzer may further include a sample preparation device and a detection device (not shown). The sample preparation device is used to provide a reaction site for the sample to be tested and the processing reagent collected by the sampling needle 231 to prepare a sample liquid to be tested. The detection device is used to detect the sample liquid to be tested. The control device is also electrically connected to the sample preparation device and the detection device respectively to control the entire operation process of the sample analyzer from transporting the sample to collecting the sample, preparing the sample liquid and finally detecting the sample liquid. At this time, when the identification reading device 24 detects the identification portion 852, the control device controls the sample preparation device to prepare a sample liquid to be tested with a first dilution; when the identification reading device 24 does not detect the identification portion 852, the control device controls the sample preparation device to prepare a sample liquid to be tested with a second dilution less than the first dilution. Optionally, the subsequent measurement time of the sample liquid to be tested prepared by the detection device for a micro sample is longer than the measurement time of the sample liquid sample to be tested prepared for a constant sample.

[0070] In some embodiments, the identification portion carries information about the type of the micro-sample container and its corresponding first height. When the identification reading device detects the identification portion, the control device directly obtains the type of the current micro-sample container and its corresponding first height from the identification portion. These embodiments are particularly suitable for situations where the identification portion is a barcode label, a QR code, or an RFID.

[0071] In other embodiments, the identification portion only carries the type information of the micro-sample container. In this case, a preset correspondence between the micro-sample container and the first height information is pre-stored in the control device (or the memory of the control device). When the identification reading device 24 detects the identification portion 852, the control device obtains the corresponding first height based on the type information of the identification portion 852 and the pre-stored preset correspondence. Of course, an input device can also be provided to receive a user-set preset correspondence between the stored micro-sample container and the first height information, or to receive a user's change to the stored preset correspondence, such as changing the height information.

[0072] For example, when multiple microsample containers with different inner cavity bottom heights are used simultaneously, distinct identification portions 852 can be provided on the microsample container fixture 85 to represent different special information, each of which represents or corresponds to a different sampling needle downward displacement height. For example, different barcode labels can be provided on the fixture 85, such as Axxx indicating that the microsample container carried by the fixture 85 is a first-class microsample container, Bxxx indicating that the microsample container carried by the fixture 85 is a second-class microsample container, and Cxxx indicating that the microsample container carried by the fixture 85 is a third-class microsample container. A lookup table for multiple special information and sampling needle downward displacement heights (first heights) can also be preset in the memory of the control device, such as Axxx corresponding to a sampling needle downward displacement height of h1, Bxxx corresponding to a sampling needle downward displacement height of h2, and Cxxx corresponding to a sampling needle downward displacement height of h3.

[0073] In some embodiments, the control device controls the sampling needle 231 to move down to different heights by controlling the driving stroke or driving time of the lifting motor 233 .

[0074] In some embodiments, the control device can also control the downward movement of the sampling needle 231 to the first height position or the second height position by stopping the sampling needle 231 after it contacts the bottom 911a of the cavity of the micro-sample container 91 or the bottom 901a of the large-volume sample container 90. It will be appreciated that when the sampling needle 231 contacts the bottom of the cavity of the micro-sample container 91 or the large-volume sample container 90, effective sample extraction by the sampling needle 231 is ensured. It will be appreciated that the lifting motor 233 can be a stepper motor. A stepper motor can change its output torque based on the current supplied. Once a load exceeding the motor torque is applied to the stepper motor, it will lose step. For example, after the sampling needle 231 contacts the bottom of the micro-sample container 91 or the large-volume sample container 90, the stepper motor 233 may lose step and stall, thereby stopping. The control device can detect whether the sampling needle 231 has contacted the bottom of the micro-sample container 91 or the large-volume sample container 90 by detecting whether the lifting motor 233 has lost step.

[0075] In some embodiments, when the control device controls the sample processing device to process the sample according to a first sample processing condition, the control device causes the lifting motor to operate at a first driving current to drive the sampling needle down to the bottom of the cavity of the micro sample container for sampling. When the control device controls the sample processing device to process the sample according to a second sample processing condition different from the first sample processing condition, the control device causes the lifting motor to operate at a second driving current greater than the first driving current to drive the sampling needle down to the bottom of the cavity of the constant sample container for sampling.

[0076] For example, the control device controls the lifting motor 233 to always drive the sampling needle 231 downward with the second height corresponding to the constant blood collection tube 90 as the target. When the identification reading device 24 detects the identification portion 852, the control device sets the driving current of the lifting motor 233, such as a stepping motor, to a first value. When the front end of the sampling needle 231 touches the bottom of the cavity of the micro sample container 91, the stepping motor loses step and stops working. Therefore, since the front end of the sampling needle 231 hits the bottom of the cavity of the micro sample container, causing the motor to stop working, the sampling needle 231 stops at the bottom of the cavity of the micro sample container before moving down to the second height ( Figure 15the sample needle 231 can reliably aspirate the sample in the micro sample container with a small sample volume. Moreover, the first driving current is set to be small, so that even if the front end of the sample needle 231 touches the bottom of the inner cavity of the micro sample container, the micro sample container will not be damaged. When the identification reading device 24 does not detect the identification portion 852, the control device sets the driving current of the lifting motor 233, for example, the stepper motor 232, to a second value greater than the first value, so that the lifting motor 233 can drive the sample needle 231 to puncture the puncture area 902a of the cap 902 of the macro sample container 90 with sufficient force, and then move downward to a second height (D position in FIG. 8B) set by the control device. Figure 15

[0077] Further, the control device can detect whether the lifting motor 233 is stalled when controlling the lifting motor 233, so as to stop the lifting motor 233 as soon as possible when the lifting motor 233 is stalled, further reducing the risk of damage to the sample needle 231 and the sample container.

[0078] In some alternative embodiments, when the control device controls the sample processing device to process the sample under a first sample processing condition, the control device controls the lifting motor to operate at a first driving current to drive the sample needle to move downward to the bottom of the inner cavity of the micro sample container for sampling; and when the control device controls the sample processing device to process the sample under a second sample processing condition different from the first sample processing condition, the control device controls the lifting motor to first operate at a second driving current greater than the first driving current to drive the sample needle to move downward to a predetermined height in the macro sample container, and then controls the lifting motor to operate at a third driving current less than the second driving current to drive the sample needle to continue to move downward to the bottom of the inner cavity of the macro sample container for sampling. When the sample in the macro sample container 90 needs to be aspirated, i.e., when the identification reading device 24 does not identify the identification portion 852, the lifting motor 233 needs a larger driving force to drive the sample needle 231 to puncture the puncture area 902a, so as to ensure that the sample needle 231 passes through the first cap 902. However, if the lifting motor 233 continues to drive the sample needle 231 to move downward with a larger driving force, the sample needle 231 may Figure 15 Figure 15 ​​When the sample in the micro-sample container 91 needs to be aspirated, that is, when the identification reading device 24 recognizes the identification portion 852, because the sampling needle 231 generally does not need to pierce any object when inserting into the micro-sample container 91, the control device can control the lifting motor 233 to directly drive the sampling needle 231 downward with a smaller first driving current.

[0079] In other alternative embodiments, the control device controls the lifting motor 233 to drive the sampling needle 231 downward in the same driving manner regardless of whether the identification reading device 24 reads the identification portion 852. That is, during sampling, the control device controls the lifting motor 233 to operate at a first driving current to drive the sampling needle 231 downward into the micro-sample container or the large-sample container until it reaches a predetermined height above the bottom of the sample container's cavity. After the sampling needle 231 reaches the predetermined height, the control device controls the lifting motor 233 to operate at a second driving current, which is lower than the first driving current, to drive the sampling needle 231 further downward until it reaches the bottom of the micro-sample container or the large-sample container's cavity.

[0080] For the constant-volume sample container 90, when the lifting motor 233 drives the sampling needle 231 downward to a predetermined height position with a first driving current, the sampling needle 231 can be ensured to smoothly pierce the tube cap 902. Then, when the lifting motor 233 drives the sampling needle 231 downward again with a second driving current, regardless of whether the sampling needle 231 contacts the bottom of the constant-volume sample container 90, no significant impact is caused to the bottom of the constant-volume sample container 90, thereby protecting both the constant-volume sample container 90 and the sampling needle 231 while ensuring effective sampling. For the micro-volume sample container 91, when the lifting motor 233 drives the sampling needle 231 downward to a predetermined height position with a first driving current, regardless of whether the micro-volume sample container 91 is capped, the sampling needle 231 can smoothly move downward to the predetermined height position. Then, when the lifting motor 233 drives the sampling needle 231 downward with the second driving current, the sampling needle 231 contacts the bottom of the micro-sample container 91. Because the second driving current is smaller, the bottom of the micro-sample container 91 is not significantly impacted, thereby simultaneously protecting the micro-sample container 91 and the sampling needle 231 while ensuring effective sampling. On the one hand, the first driving current of the lifting motor 233 is designed to match the caps of the micro-sample container 91 and / or the normal sample container 90, ensuring that the sampling needle 231 can pierce the caps when the lifting motor 233 drives the sampling needle 231 downward to a predetermined height with the first driving current. On the other hand, the second driving current of the lifting motor 233 is designed to match the micro-sample container 91, ensuring that the lifting motor 233 does not pierce the sample container when the second driving current drives the sampling needle 231 downward to the bottom of the sample container.

[0081] For example, the control device controls the lifting motor 233 to always drive the sampling needle 231 downward at the second height corresponding to the normal sample container 90. The control device first sets the driving current of the lifting motor 233 to a first value. When the sampling needle 231 has descended to a height lower than the cap 902 of the normal sample container 90 by a specific value (the specific value satisfies that the front end of the sampling needle has already fallen below the cap 902 of the normal sample container 90 but has not touched the bottom of the cavity of the micro sample container 91), the sampling needle 231 is lowered to a height lower than the cap 902 of the normal sample container 90 by a specific value. Figure 15 At the height position B shown in FIG. 1 , the control device sets the driving current of the lifting motor 233 to a second value smaller than the first value. If the sampling needle 231 is sucking a sample from the micro sample container 91, the lifting motor 233 will be locked and stopped when the front end of the sampling needle 231 touches the bottom 911a of the cavity of the micro sample container 91, so that the front end of the sampling needle 231 always stays at the bottom 911a of the cavity of the micro sample container 91. Figure 15 If the sampling needle 231 of the sample suction object is a constant sample container 90, the front end of the sampling needle 231 will eventually drop to a second height, such as Figure 15 D height position shown.

[0082] Furthermore, the control device also includes a driver chip with a motor stall detection function. This driver chip is configured to control the operation of the lifting motor 233, monitor whether the lifting motor 233 is stalled while controlling the lifting motor 233, and control the lifting motor 233 to stop operating if it is determined that the lifting motor 233 is stalled. It can be understood that by using the driver chip with a motor stall detection function to monitor the lifting motor 233 for stall, it can actually be determined whether the front end (needle tip) of the sampling needle 231 contacts the bottom of the sample container cavity.

[0083] In some embodiments, the driver chip determines whether the lifting motor 233 is stalled according to the rotation speed or back electromotive force of the lifting motor 233 .

[0084] Specifically, the lifting motor 233 can be a stepper motor with a stator and a rotor cooperating with each other. The stator is wound with a coil, and the rotor is fixed with a silicon steel sheet. The driving chip controls the current size and direction of the coil in the stator to generate an alternating magnetic field, which interacts with the silicon steel sheet of the rotor to generate a rotating magnetic force to drive the rotor to rotate. While the rotor is rotating, an alternating magnetic field is generated around the coil of the stator, which interacts with the coil of the stator to induce an electric field, which is defined as a back electromotive force. Generally, the higher the motor speed, the greater the back electromotive force induced by the coil of the stator. Therefore, the driving chip can detect whether the lifting motor 233 has stalled by detecting the speed or back electromotive force of the motor, i.e., the driving chip can detect the working state of the lifting motor 233 by continuously detecting the change of the speed or back electromotive force of the lifting motor 233. For example, when the driving chip detects that the speed or back electromotive force of the lifting motor 233 decreases to 0 or approaches 0, it can be judged that the lifting motor 233 has stalled, and accordingly the working of the lifting motor 233 is stopped to avoid the lifting motor 233 continuously driving the sampling needle 21 to move downward and impacting the bottom of the cavity of the sample container 200, and to shorten the noise duration generated after the motor 22 stalls. In addition, a threshold value (greater than 0) for the speed or back electromotive force can also be set, and when the driving chip detects that the speed or back electromotive force of the lifting motor 233 decreases to the threshold value, it can be judged that the lifting motor 233 has stalled, and the working of the lifting motor 233 is stopped in advance to further reduce the impact of the lifting motor 233 driving the sampling needle 231 on the bottom of the cavity of the sample container.

[0085] In some embodiments, the model of the driving chip can include TMC5130, TMC5160 or TMC5161 of TRINAMIC Company with automatic detection of motor stall function. The motor driving chips of these models can calculate the back electromotive force generated by the lifting motor 233 at different speeds according to the coil resistance and inductance parameters of the lifting motor 233, i.e., they can detect the back electromotive force generated by the driving circuit of the lifting motor 233 when the lifting motor 233 is rotating, and thus are suitable for use in the sample analyzer 100 of the application.

[0086] As for the specific form of the identification portion 852 on the fixing part 85, in different embodiments, it can be set to one of a specific color, material, and shape, or it can be set to one of the forms such as a radio frequency tag (RFID), a barcode tag (such as a barcode or a QR code tag). Of course, the identification portion 852 can also adopt a combination of two or more of any of the above forms. Correspondingly, the identification reading device 24 can include one or more of a color recognition sensor, a metal detection sensor, a shape recognition sensor, a camera (by shooting an image or video, processing the image or video through software, and extracting the characteristic information of the fixing part 85) and a barcode scanner. In Figure 8a and Figure 8b In the illustration, the identification portion 852 is preferably configured as a barcode label, and the identification reading device 24 is correspondingly configured as a barcode scanner that can read the barcode label.

[0087] The identification portion 852 and the barcode label 852 are at least partially fixed around the outer wall of the fixing member 85 (eg Figure 8a As shown) or attached to the entire outer wall of the fixing member 85 (as shown Figure 8b When the identification reading device 24 scans the outer wall of the fixing member 85 , the identification information of the fixing member 85 can be read from the identification portion 852 that at least partially surrounds the fixing member 85 .

[0088] See Figure 8c (correspond Figure 8a )and Figure 8d (correspond Figure 8b To prevent wear on the identification portion 852, the fixing member 85 is further provided with a groove 853 corresponding to the location of the identification portion 852. When the fixing member 85 is placed in the sample rack 80, the identification portion 852, which is attached to the groove 853, is protected from wear by the fixing hole 801. The fixing member 85 is typically reused, and each time it carries a different microsample container 91. Therefore, the provision of the groove 853 can extend the service life of the fixing member 85.

[0089] As mentioned above, when the sample in the micro-sample container 91 needs to be mixed, the fixing member 85 usually needs to be transported to the first mixing device 21 along with the micro-sample container 91. Therefore, the sample processing device 2 in the sample analyzer 1 is usually also provided with a clamping claw for transporting the fixing member 85 and the micro-sample container 91, such as the second mixing device 22 mentioned above. Therefore, in order to prevent the clamping claw from wearing the marking portion 852 during the process of clamping the fixing member 85, a clamping area 854 (such as Figure 8a As shown), the identification portion 852 is fixed below the clamping area 854.

[0090] Figure 16A flow chart of a sample analysis method according to the present invention is shown, which specifically includes the following steps:

[0091] S101. Using the identification reading device 24, a sample container on the sample rack 80 that can hold a mixture of micro sample containers 91 and normal sample containers 90 is identified. The micro sample container can hold fewer samples than the normal sample container. The micro sample container 91 is fixed in the fixing hole 801 of the sample rack 80 via a fixing member 85. The fixing member 85 is provided with an identification portion 852 indicating that the sample container is a micro sample container 91.

[0092] S102, when the identification reading device 24 detects the identification portion 852 of the fixing member 85, the sample processing device 2 is controlled to process the sample according to the first sample processing condition;

[0093] S103 : When the identification reading device 24 does not detect the identification portion 852 of the fixing member 85 , the sample processing device 2 is controlled to process the sample according to a second sample processing condition different from the first sample processing condition.

[0094] Specifically, similar to the principle of the sample analyzer 1 described above, the method of the present invention first secures the micro-sample container 91 to the fixing hole 801 of the sample rack 80 using a fixing member 85 with an identification portion 852. The identification portion 852 is then recognized by the identification reading device 24 to determine whether the sample container currently being processed is a micro-sample container. It is understood that when the identification reading device 24 recognizes the identification portion 852, the sample container currently being processed is determined to be a micro-sample container, and the first sample processing conditions are used to process the sample in the micro-sample container. When the identification reading device 24 does not recognize the identification portion 852, the sample container currently being processed is determined to be a normal sample container, and the sample in the normal sample container is subsequently processed using a second sample processing condition that is different from the first sample processing condition.

[0095] By utilizing the sample analysis method of the present invention, micro sample containers 91 and constant sample containers 90 can be mixed and placed in the sample rack 80, and the types of the mixed sample containers can be judged. Based on the judgment results, the samples in the different types of sample containers are processed using matching sample processing conditions, thereby improving the intelligent sample analysis capability of the sample analyzer 1 and avoiding the defect of damaging the micro blood sample container 91 or the sampling needle 231 of the sampling device 23 due to incorrect placement of the sample container.

[0096] For an example, see Figure 17 Before step S101, the sample analysis method further includes:

[0097] S90, receiving the identity information of the micro-sample container 91 placed on the sample rack 80 and the identity information of the fixing member 85 used to fix the micro-sample container 91 on the sample rack 80;

[0098] S91, establishing a one-to-one correspondence between the identity information of the micro-sample container 91 and the identity information of the corresponding fixing member 85, wherein the identification portion 852 includes the type information of the micro-sample container 91 and the identity information of the fixing member 85;

[0099] Then, when the identification reading device 24 detects the identification portion 852, the method further includes:

[0100] S104 , obtaining the sample type information and identity information of the corresponding micro sample container 91 according to the information and association relationship contained in the identification portion 852 .

[0101] Specifically, the identification portion 852 on the fixture 85 can also be used to identify the type and identity information of the micro-sample container 91 it carries. Before the sample analyzer 1 analyzes and tests the sample, the identity information of the micro-sample containers 91 on the sample rack 80 can be pre-entered, and the identity information of the fixture 85 on which each micro-sample container 91 is placed can be simultaneously entered. A one-to-one correspondence is then established between the identity information of each micro-sample container 91 and the identity information of the fixture 85 on which it is placed. By identifying the identification portion 852, the identification reader 24 can use this correspondence to locate the identity information of the micro-sample container 91 corresponding to the fixture 85.

[0102] For an example, see Figure 18 Step S102 includes: step S102a, mixing the sample in the micro sample container 91 under a first mixing condition. Step S103 includes: step S103a, mixing the sample in the constant sample container 90 under a second mixing condition different from the first mixing condition.

[0103] In one embodiment, the sample processing device 2 includes a first mixing device 21 and a second mixing device 22. Accordingly, step S102a includes: mixing the sample in the micro sample container 91 using the first mixing device 21; and step S103a includes: mixing the sample in the macro sample container 90 using the second mixing device 22.

[0104] Because the sample types and sample capacities in the trace sample container 91 and the constant sample container 90 are different, the mixing methods for the trace sample container 91 and the constant sample container 90 also need to be operated differently. By setting different first mixing device 21 and second mixing device 22, the mixing actions of the trace sample container 91 and the constant sample container 90 are realized respectively, which is beneficial to improve the mixing effect of different samples.

[0105] Further, when driving the first mixing device 21 to mix the sample in the trace sample container 91, the fixed part 85 can be driven to rotate together with the trace sample container 91 placed in the fixed part 85 to mix the sample in the trace sample container 91.

[0106] In view of the small volume of the trace sample container 91, it is not convenient to mix separately. Therefore, when mixing the trace sample container 91 by the first mixing device 21, the fixed part 85 holding the trace sample container 91 can be mixed together, that is, the fixed part 85 and the trace sample container 91 placed in the fixed part 85 can be rotated together to improve the mixing effect in the trace sample container 91.

[0107] On the other hand, the second mixing device 22 can be configured as a mixing clamp. When driving the second mixing device 22 to mix the sample in the constant sample container 90, the second mixing device 22 can be used to clamp and swing the constant sample container 90 to mix the sample in the constant sample container 90.

[0108] Specifically, because the sample capacity in the constant sample container 90 is large, when mixing the constant sample, the second mixing device 22 configured as a mixing clamp can be used to swing the constant sample container 90 to realize the mixing operation of the constant sample container 90.

[0109] Further, because the second mixing device 22 is configured as a mixing clamp, the second mixing device 22 has the ability to clamp and transfer the sample container. Therefore, when the sample in the trace sample container 91 needs to be mixed, the second mixing device 22 can also be used to transfer the fixed part 85 together with the trace sample container 91 placed in the fixed part 85 to the first mixing device 21.

[0110] Using the second mixing device 22 to realize the operation of transferring the fixed part 85 and the trace sample container 91 placed in the fixed part 85 from the sample rack 80 to the first mixing device 21 can effectively utilize the structure of the second mixing device 22, and eliminate the need to specially configure a mechanical arm for the first mixing device 21 to transfer the trace sample container 91, thereby saving the internal space of the sample analyzer 1.

[0111] Figure 19a and Figure 19b The flow chart for mixing the sample in the micro sample container 91 and the flow chart for mixing the sample in the constant sample container 90 are respectively shown. Figure 19a As shown, when mixing the sample in the micro-sample container 91, first use the second mixing device 22 to clamp the fixing part 85 connected to the micro-sample container 91 from the sample rack 80, then lift the fixing part 85 and drive the micro-sample container 91 to rise and leave the sample rack 80. The second mixing device 22 transfers the fixing part 85 and the micro-sample container 91 to the top of the first mixing device 21 by translation, and then puts the two into the first mixing device 21 and the second mixing device 22 retracts. The first mixing device 21 starts to rotate the fixing part 85 and drives the micro-sample container 91 to mix. When the mixing work of the micro-sample is completed, the second mixing device 22 repeats the above operation in reverse and puts the micro-sample container 91 and the fixing part 85 back on the sample rack 80. As shown Figure 19a As shown, the mixing of the sample in the constant sample container 90 is independently completed by the second mixing device 22. After the clamping claws of the second mixing device 22 grasp the constant sample container 90, they first lift the constant sample container 90 to a safe area, then drive the constant sample container 90 to swing back and forth at a set angle. After the mixing times meet the specified number, the mixing operation is completed and the constant sample container 90 is returned to the sample rack 80.

[0112] See Figure 20 In the embodiment, step S102 includes: step S102b, controlling the lifting motor 233 to drive the sampling needle 231 to move down to a first height to sample the micro sample container 91; step S103 includes: step S103b, controlling the lifting motor 233 to drive the sampling needle 231 to move down to a second height to sample the constant sample container 90, wherein the second height is different from the first height, in particular, lower than the first height.

[0113] By setting the first height and the second height of the downward movement of the sampling needle differently for different sample containers, it is possible to ensure that the sampling needle 231 can effectively collect trace samples and constant samples respectively.

[0114] Furthermore, since the micro sample container 91 is fixed to the sample rack 80 via the fixing member 85 , the bottom of the cavity of the micro sample container 91 is correspondingly raised. Therefore, it is preferable to set the first height higher than the second height to ensure that the downward position of the sampling needle 231 can absorb the corresponding sample.

[0115] In one embodiment, the micro-sample container 91 may include at least a first micro-sample container and a second micro-sample container having different cavity heights. Accordingly, step S102b further includes the following sub-steps:

[0116] When the identification portion 852 detected by the identification reading device 24 indicates that the micro-sample container 91 is the first micro-sample container, the sampling needle 231 is controlled to move downward to a first height corresponding to the first micro-sample container to sample the first micro-sample container;

[0117] When the identification portion 852 detected by the identification reading device 24 indicates that the micro-sample container 91 is the second micro-sample container, the sampling needle 231 is controlled to move downward to the first height corresponding to the second micro-sample container to sample the second micro-sample container.

[0118] Because the first and second micro-sample containers have different cavity heights, when placed on the same sample rack, the bottom of the cavity of each micro-sample container will be at different distances from the bottom of the sample rack. By identifying the type of micro-sample container 91 using the identification reader 24, the first height can be more accurately controlled, ensuring that the sampling needle 231 can be lowered to the height corresponding to that type of micro-sample container, thereby ensuring that the sampling needle 231 can effectively collect the sample in that type of micro-sample container.

[0119] In some embodiments, the first height is obtained in the following manner, namely: the identification portion 852 carries the type information of the micro-sample container and its corresponding first height information, and when the identification reading device detects the identification portion 852, the type of the current micro-sample container and its corresponding first height are obtained from the identification portion; or the identification portion 852 only carries the type information of the micro-sample container, and a preset correspondence between the type of the micro-sample container and the first height is pre-stored, and when the identification reading device detects the identification portion 852, the corresponding first height is obtained according to the type information and the preset correspondence.

[0120] Furthermore, step S102b may include controlling the sampling needle 231 to move downward to a first height by controlling the driving stroke or driving time of the lifting motor 233; and step S103b may include controlling the sampling needle 231 to move downward to a second height by controlling the driving stroke or driving time of the lifting motor 233. In other words, the downward height of the sampling needle 231 may be controlled by controlling the driving stroke or driving time of the lifting motor 233.

[0121] For an example, see Figure 21 Step S102 may include: step S102c, operating the lifting motor 233 with a first driving current, and when the lifting motor 233 is blocked, stopping the lifting motor 233 so that the sampling needle 231 can move down to the bottom 911a of the cavity of the micro sample container 91 for sampling; step S102 may include: step S103c, operating the lifting motor 233 with a second driving current greater than the first driving current, so as to drive the sampling needle 231 to move down to a second height to sample the constant sample container 90.

[0122] When sampling the constant sample container 90, it is necessary to ensure that the sampling needle 231 passes through the first tube cap 902. Therefore, the sampling needle needs to be lowered with a large force, that is, the driving current of the lifting motor 233 is large; at the same time, in order to prevent the sampling needle 231 from causing damage to the micro sample container 91 when contacting the bottom 911a of the micro sample container 91, the driving current of the lifting motor 233 is small when sampling the micro sample container 91.

[0123] Alternatively, regardless of whether the identification reading device 24 reads the identification portion 852, the lifting motor 233 is controlled to drive the sampling needle 231 downward using the same driving method. That is, during sampling, the lifting motor 233 is controlled to operate at a first driving current to drive the sampling needle 231 downward into the micro-sample container or the large-sample container until it reaches a predetermined height above the bottom of the sample container's cavity. After the sampling needle 231 reaches the predetermined height, the lifting motor 233 is controlled to operate at a second driving current, which is lower than the first driving current, to drive the sampling needle 231 further downward until it reaches the bottom of the micro-sample container or the large-sample container's cavity.
