[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0050] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] Hematology analyzers and dry-type fluorescence immunoassay analyzers are both common testing equipment in the laboratory. When blood cell analysis and immunoassay (such as CRP / SAA) need to be performed on samples simultaneously, two instruments must be operated to complete the task, which consumes a lot of manpower and time. In addition, conventional fluorescence immunoassay analyzers cannot be adaptively adjusted according to different blood samples, resulting in certain deviations in the results.

[0052] The main purpose of the utility model is to provide a blood cell and fluorescence immunoassay analyzer, aiming to solve the problems of cumbersome operation and large deviation of analysis results in existing blood cell analysis and immunoassay.

[0053] See also Figure 1 The present invention proposes a blood cell and fluorescent immunoassay analyzer 1000, comprising a rack 1, a whole blood sample component 2, an immune reagent component 3, a blood cell counting component 4, an immune analysis component 5, and a sampling component 6. The rack 1 has a first station, a second station, a third station, and a fourth station arranged at intervals along a first direction or a second direction. The whole blood sample component 2 is located at the first station for storing whole blood samples, the immune reagent component 3 is located at the second station for storing immune reagents, the blood cell counting component 4 is located at the third station for classifying and counting whole blood samples and obtaining HCT values of whole blood samples, the immune analysis component 5 is located at the fourth station for performing fluorescent immunoassay on whole blood samples, and the sampling component 6 is movably arranged on the rack 1. The movable stroke of the sampling component 6 passes through the first station, the second station, the third station, and the fourth station for transferring corresponding samples or reagents.

[0054] The technical solution of the present invention is to provide the whole blood sample component 2, the immune reagent component 3, the blood cell counting component 4, and the immune analysis component 5, and respectively provide them at the first, second, third, and fourth stations arranged at intervals, so that blood cell analysis and fluorescent immunoassay are integrated into a single instrument, and the samples in the blood cell analysis can be simultaneously applied to the immune analysis, saving costs and improving analysis efficiency. The transfer of samples or reagents is achieved by providing the sampling component 6, which facilitates operation. Furthermore, the present device uses whole blood as the analysis object, and through the blood cell counting component 4, the HCT value of the whole blood sample is obtained while performing blood cell analysis, thereby correcting the impact of different blood samples on the immune analysis results, thereby improving the accuracy of the analysis results.

[0055] It should be noted that the HCT value of a whole blood sample refers to the percentage of blood volume occupied by red blood cells (RBCs), which reflects the blood's viscosity and the degree of RBC concentration. In some cases, changes in the HCT value may affect the results of a fluorescent immunoassay, particularly when the analyte is present in plasma or serum, where changes in RBC concentration can affect the total sample volume and the dilution of the analyte. For example, if a patient is dehydrated, their HCT value will increase because the reduced water content leads to a relative concentration of RBCs. This can cause the analyte concentration in plasma or serum to appear higher than it actually is because the sample is "concentrated" by RBCs. Conversely, overhydration or hemodilution can also cause the HCT value to decrease, making the analyte concentration appear lower. Therefore, when performing a fluorescent immunoassay using a whole blood sample, the HCT value should be included to adjust the analysis results to ensure that they accurately reflect the actual analyte concentration.

[0056] It is worth mentioning that, during a complete analysis process, the specific movement stroke of the sampling component 6 includes: moving from the first station to the third station to transfer the whole blood sample to the blood cell counting component 4 for blood cell analysis and calculation of the HCT value, moving from the second station to the third station to mix the immune reagent with the whole blood sample in the red blood cell counting pool to obtain a mixed reagent, and moving from the third station to the fourth station to transfer the mixed reagent to the immune analysis component 5 for immune analysis.

[0057] The blood cell counting assembly 4 is conventional technology and specifically includes a white blood cell counting pool, an red blood cell counting pool, a DIFF pool, and an analyzer. The white blood cell counting pool is used to receive a whole blood sample, separate white blood cells and red blood cells, and count the white blood cells; the red blood cell counting pool is used to receive the red blood cells distributed from the white blood cell counting pool and count the red blood cells; the DIFF pool is used to classify and count the white blood cells; and the analyzer integrates and analyzes the above data to obtain the blood cell analysis results and the HCT value of the whole blood sample.

[0058] It is understandable that, in the process of switching from transferring one reagent to transferring another reagent, the sampling component 6 needs to be cleaned to avoid contaminating the reagent in the container.

[0059] To implement the function of fluorescent immunoassay, please refer to Figure 2 and Figure 3The immunoassay assembly 5 includes a reagent card mounting portion 51 and a fluorescence reader 52. The reagent card mounting portion 51 is located in the fourth station and can be movably mounted in the first direction. The reagent card mounting portion 51 is used to mount a reagent card. The fluorescence reader 52 is located in the fourth station and is positioned opposite the reagent card on the reagent card mounting portion 51. It is used to read the fluorescence intensity of the reagent card during the movement of the reagent card mounting portion 51. This arrangement allows for the detection of immune parameters using dry immunoassay strips, which is convenient to use. Furthermore, the specific immunoassay reagent does not require cryogenic storage, which reduces reagent costs and avoids reagent waste.

[0060] It's worth noting that in this embodiment, the fluorescence reader 52 is configured as a fluorescence generator and a fluorescence receiver. The fluorescence generator's excitation light source has a wavelength between 350nm and 415nm, while the fluorescence receiver's wavelength is between 550nm and 660nm. When the excitation light shines on the reagent card, it stimulates the fluorescent material on the card to emit light, forming T and C lines. These are then converted through a number of optical paths into light of specific wavelengths for detection. By comparing the relationship between T and C lines, immunoassay data can be obtained.

[0061] Please refer to Figure 3 In one embodiment of the present invention, the fluorescent reader 52 is movable along a second direction. During the movement of the reagent card mounting portion 51, the fluorescent reader 52 sequentially moves above the reagent cards positioned in the second direction, thereby reading the fluorescence intensity of multiple reagent cards spaced apart along the second direction. With this arrangement, the reagent card mounting portion 51 is provided with multiple positions for reagent card installation, and the fluorescent reader 52 is synchronously movable. This allows the fluorescent reader 52 to read reagent cards in other positions while replacing a reagent card in one position. Compared to a single-channel arrangement, the multi-channel approach of this embodiment achieves higher card reading efficiency.

[0062] It should be understood that this solution does not limit the specific implementation of the movement of the fluorescent reading head 52. In one embodiment, the fluorescent reading head 52 is connected to a cylinder rod of a pneumatic cylinder, and the cylinder rod extends along the second direction. In another embodiment, the fluorescent reading head 52 is connected to the output shaft of a stepper motor to achieve movement in the second direction.

[0063] In another embodiment, to further improve card reading speed, multiple fluorescent reading heads 52 are spaced apart along the second direction, each fluorescent reading head 52 being configured to correspond one-to-one with a reagent card on the reagent card mounting portion 51. This arrangement enables simultaneous reading of multiple reagent cards, resulting in higher work efficiency.

[0064] In order to realize the movement of the reagent card installation part 51, in one embodiment of the present invention, please refer to Figure 2 The immunoassay assembly 5 further includes a mounting seat 53, a cylinder 54, a movable block 55, and at least one guide rod 56. The mounting seat 53 is located at the fourth station, the cylinder 54 is located at the mounting seat 53, the cylinder rod of the cylinder 54 extends in a first direction, the movable block 55 connects the reagent card mounting portion 51 and the cylinder rod, so as to drive the reagent card mounting portion 51 to move in the first direction under the drive of the cylinder 54, and the at least one guide rod 56 extends in the first direction. The guide rod 56 is fixed to the mounting seat 53, and the end of the guide rod 56 passes through the movable block 55. By providing the guide rod 56, the movement direction of the movable block 55 is guaranteed, thereby improving the stability of the immunoassay assembly 5. It will be understood that this solution does not limit the specific implementation form of the movement of the reagent card mounting portion 51. In another embodiment, the movable block 55 is connected to the output shaft of the stepping motor to achieve movement in the first direction.

[0065] To ensure that the reagent card can be inserted into the corresponding position, in one embodiment of the present invention, the immunoassay assembly 5 further includes a detector 57, which is located at the side of the reagent card installation portion 51 and is used to detect the installation status of the reagent card. In this configuration, when the detector 57 detects the insertion of a reagent card, this information can be fed back to the host computer, indicating that the card position is suitable for dripping the mixed reagent, thereby improving the automation level of the device.

[0066] It is understandable that this solution does not limit the specific implementation form of the detector 57. For example, in one embodiment, the detector 57 is set as an infrared sensor; in another embodiment, the detector 57 is set as a pressure sensor. Users can adopt different strategies according to actual conditions.

[0067] In order to perform information management of different samples, in one embodiment of the present invention, the immunoassay assembly 5 further includes a barcode scanner 58. The barcode scanner end of the barcode scanner 58 is positioned toward the reagent card mounting portion 51 and is configured to scan the QR code of the reagent card mounted on the reagent card mounting portion 51. The provision of the barcode scanner 58 enables information corresponding to the sample on the reagent card to be uploaded to the host computer, facilitating data aggregation and storage in the background. It is understood that the QR code on the reagent card stores information such as the tester, test item, and test time, which is not specifically limited herein.

[0068] In one embodiment of the present invention, the immunoassay assembly 5 further includes a temperature detection device and a heating device. The temperature detection device is located on the reagent card mounting portion 51 and is used to detect the temperature of the reagent card. The heating device is located on the reagent card mounting portion 51 and is electrically connected to the temperature detection device and is used to heat the reagent card based on the detection result of the temperature detection device. During immunoassay, the treated test sample is quantitatively added to the sample loading position of the reagent card and then left to incubate for 2-5 minutes. By using the temperature detection device and the heating device together, the sample incubation temperature is kept within a reasonable temperature range, thereby improving the sample incubation success rate and thus ensuring the reliability of the immunoassay results.

[0069] In one embodiment of the present invention, please refer to Figure 4 , the immune reagent component 3 includes a reagent bottle 31 provided at the second station, and the position of the reagent bottle 31 is adjustable in the first direction or the second direction. By setting the position-adjustable reagent bottle 31, it is convenient to accommodate the immune reagent without using it, saving space. Specifically, the immune reagent component 3 is also provided with a sliding fit structure 32 and a limiter 33. The reagent bottle 31 is provided on the sliding fit structure 32 to slide under the guidance of the sliding fit structure 32. The limiter 33 is provided on the third station to limit the sliding stroke of the reagent bottle 31. The driving mode of the reagent bottle 31 can be manual or electrically controlled by the driving device, which is not limited here. The limiter 33 can be a positioning pin provided on the sliding fit structure 32, or a block provided on the third station, which is not specifically limited here.

[0070] In one embodiment of the present invention, please refer to Figure 1 The blood cell and fluorescence immunoassay analyzer 1000 also includes an optical mixing cup 7 mounted on the housing 1. This optical mixing cup 7 is used to classify the white blood cell sample in the blood cell counting assembly 4. The optical mixing cup 7 is capable of centrifuging the white blood cell sample. Because different cell types have different densities, they are distributed according to their density under the action of centrifugal force, thereby classifying the white blood cell sample and providing raw data for blood cell analysis. It is understood that the sampling assembly 6 can be moved to the optical mixing cup 7 to transfer the white blood cell sample there for classification.

[0071] The present invention also proposes an analysis method of blood cells and fluorescent immunoassay, please refer to Figure 5 The analysis method of blood cells and fluorescent immunoassay instrument comprises the following steps:

[0072] S100: Obtaining the HCT value and blood cell analysis results calculated by the blood cell counting component 4.

[0073] S200: Control the immunoassay component 5 to perform fluorescent immunoassay on the whole blood sample in combination with the HCT value to obtain an immunoassay result.

[0074] The technical solution of the present invention calculates the HCT value while performing blood cell analysis, wherein the HCT value can be obtained by red blood cell counting, which is relatively convenient. By combining the HCT value with the fluorescence immunoassay of the whole blood sample, the actual concentration of the analyte is ensured, thereby correcting the influence of different blood samples on the immunoassay results, thereby improving the accuracy of the analysis results.

[0075] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
