Description

Technical Field

[0001] This application relates to the field of blood cell and immune detection technology, and in particular to a portable multifunctional analyzer. Background Technology

[0002] Currently, conventional blood cell analyzers and immune detection devices are independent of each other, and most are only blood cell detection devices or immune detection devices, unable to perform both detection analyses at the same time. This results in medical institutions needing to configure multiple devices to meet different testing needs, which not only takes up space but also incurs high costs.

[0003] To address this challenge, several multi-functional integrated machines combining blood cell and immunoassay detection have emerged on the market.

Existing equipment cannot simultaneously meet the following three core requirements: ① the ability to directly test whole blood samples; ② the ability to simultaneously perform blood cell morphology analysis and immunoassay; ③ ensuring that the test results meet clinical five-part differential standards.

[0026] As a preferred embodiment, the system also includes a battery compartment located on the side of the base module opposite to the placement opening and electrically connected to the main control board module.

[0027] The beneficial effects of this application are:

[0028] This portable multifunctional analyzer includes a base module, a reagent plate module, an immunoassay module, a microscope camera module, and a main control board module. The base module has at least one slot. The reagent plate module is slidably mounted on the base module. The reagent plate module has multiple reagent slots, which are spaced apart along a sliding direction perpendicular to the reagent plate module and are used to load test reagent cards. Each reagent slot corresponds to one slot, forming a detection channel. The immunoassay module is located on the base module and spans above the reagent plate module. The immunoassay module has at least one immunoassay component, and each reagent slot has one immunoassay component for performing immunoassay on the reagent card. The microscope camera module is located on the base module, close to the immunoassay module, and corresponding to the reagent slots. It is used to photograph and detect the reagent cards in the reagent slots. The main control board module is located on the base module and is arranged side by side with the microscope camera module.

[0029] The base module's ports correspond one-to-one with the reagent card slots of the reagent plate module, forming multiple independent detection channels. This allows for the simultaneous loading and corresponding detection of multiple reagent cards, increasing throughput. The strict correspondence between each reagent card slot and port prevents cross-contamination and ensures accurate results. The immunoassay module spans above the reagent plate module, with each immunoassay component aligned with a reagent card slot, enabling parallel detection of multiple reagent card samples for simultaneous immunoassay across multiple channels. The microscope camera module is positioned close to the immunoassay module and aligned with the reagent card slots. It can focus on capturing images of the same reagent card after immunoassay, such as cell morphology and test strip color development, allowing for further blood routine testing via microscopic imaging. The main control board module receives and integrates electrical signals (such as current and voltage) from the immunoassay module and image data from the microscope camera. Built-in algorithms (such as machine learning classification and signal filtering) are used to comprehensively analyze and output results, supporting real-time display or wireless data transmission, expanding remote diagnostic capabilities and improving detection accuracy. In other words, by using multi-channel immunoassay and routine blood tests, along with multiple ports, different test items can be processed in parallel, such as simultaneous fluorescence detection and microscopic observation. This enhances the analyzer's scalability and improves efficiency. In addition, the main control board coordinates the two types of test data to provide more comprehensive sample analysis results.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0044] It should be noted that the sample to be tested on the test card can be blood, urine, or feces. It is also important to know that three-part differential blood tests classify white blood cells into three categories: neutrophils, other white blood cells, and lymphocytes; five-part differential blood tests classify white blood cells into five categories: neutrophils, lymphocytes, eosinophils, basophils, and monocytes.

[0045] like Figures 1 to 9 As shown, this application provides a portable multifunctional analyzer, including a base module 1, a reagent plate module 2, an immunoassay module 3, a microscope camera module 4, and a main control board module 5; the base module 1 is provided with at least one socket 121; the reagent plate module 2 is slidably disposed on the base module 1; the reagent plate module 2 is provided with a plurality of reagent slots 21, which are spaced apart along a sliding direction perpendicular to the reagent plate module 2, and are respectively used to load test reagent cards; each reagent slot 21 is correspondingly disposed with one socket 121 to form a detection channel; the immunoassay module 3 is disposed on the base module 1 and spans across the main control board module 5. Above the reagent plate module 2; the immunoassay module 3 is provided with at least one immunoassay component 32, and each reagent card slot 21 is provided with one immunoassay component 32 for performing immunoassay on the reagent card; the microscope camera module 4 is located on the base module 1, close to the immunoassay module 3, and corresponding to the reagent card slot 21; it is used to photograph and detect the reagent card in the reagent card slot 21; the main control board module 5 is located on the base module 1 and is arranged side by side with the microscope camera module 4; the main control board module 5 is electrically connected to the immunoassay module 3 and the microscope camera module 4 respectively.

[0046] In further detail, the socket 121 of the base module 1 is set one-to-one with the reagent card slot 21 of the reagent plate module 2, forming multiple independent detection channels to enable simultaneous loading and corresponding detection of multiple reagent cards, thereby improving detection throughput. At the same time, each reagent card slot 21 and the socket 121 are strictly aligned to avoid sample cross-contamination and ensure the accuracy of detection results. The immunoassay module 3 spans above the reagent plate module 2, with each immunoassay component 32 aligned with a reagent card slot 21, enabling parallel detection of multiple reagent card samples to achieve simultaneous immunoassay detection of reagent cards through multiple channels. The microscope camera module 4 is positioned close to the immunoassay module 3 and aligned with the reagent card slot 21. It can focus on capturing images of the same reagent card after immunoassay by the immunoassay module 3, such as cell morphology and test strip color development results. Further blood routine tests can be performed using microscopic imaging. The main control board module 5 receives and integrates electrical signals (such as current and voltage) from the immunoassay module 3 and image data from the microscope camera. It comprehensively analyzes and outputs results using built-in algorithms (such as machine learning classification and signal filtering), supporting real-time display or wireless data transmission, expanding remote diagnostic capabilities, and improving detection accuracy. In other words, by using multi-channel immunoassay and blood routine tests, coupled with the multi-port 121 setup, different test items can be processed in parallel, such as simultaneous fluorescence detection and microscopic observation. This enhances the analyzer's scalability and improves efficiency. Furthermore, the main control board coordinates the two types of test data, providing more comprehensive sample analysis results.

[0047] The reagent plate module 2 is installed in a sliding manner. The immunoassay module 3 spans across the top of the reagent plate module 2, and the microscope camera module 4 is positioned close to the immunoassay module 3. Due to the sliding arrangement of the reagent plate module 2, the microscope camera module 4 can be aligned with the reagent card on the reagent card slot 21. The main control board module 5 is arranged side by side with the microscope camera module 4. The modular layout makes the overall structure more compact, occupies less space, reduces volume, and is easy to carry. It is suitable for field use, and all functions are highly integrated (detection, imaging, and analysis are integrated). In addition, the sliding reagent plate module 2 and its corresponding socket 121, as well as the multi-module combination, support quick switching of detection modes, such as immunoassay or microscopic imaging. It can change reagent cards to switch from a single immunoassay to multiple detection modes including immunoassay and microscopic analysis, adapting to different detection needs. Thus, it can realize immunoassay and routine blood tests simultaneously, and can also perform tests anytime and anywhere to meet the needs of on-demand testing.

[0048] The workflow of the portable multi-functional analyzer described in this application is as follows:

[0049] (1) Sample loading: Users can slide the reagent plate module 2 and insert the test reagent card into the corresponding slot;

[0050] (2) Start detection: The immunoassay component 32 performs immunoassay on the test reagent card, and the microscope camera takes an image after the immunoassay on the test reagent card for blood routine and other tests.

[0051] (3) Data analysis: The main control board receives and integrates data from the immune detection module 3 and the microscope camera module 4, and judges the results, such as positive / negative, by preset thresholds or models.

[0052] (4) Output report: The results are displayed on the screen or connected devices and can be stored or shared.

[0053] In this embodiment, two immunodetection components 32 are provided, each corresponding to one reagent card slot 21; each immunodetection component 32 includes a camera module 321 and a fluorescence module 322; the camera module 321 is used for photographing and detecting the reagent card; preferably, the camera module 321 is a colloidal camera; the fluorescence module 322 is used for fluorescence detection of the reagent card; preferably, the fluorescence module 322 includes an excitation light source and a fluorescence signal receiving unit, used for exciting and collecting fluorescence signals from the fluorescent markers in the reagent card. The light signal is used to perform corresponding fluorescence detection on the reagent card; under the joint detection of the colloidal gold camera and the fluorescence module 322, the immunoassay of the reagent card is realized; it also includes an immunoassay fixing plate 31 disposed on the base module 1, and the colloidal gold camera and the fluorescence module 322 are both fixed to the immunoassay fixing plate by copper studs 33; it should be noted that the immunoassay module 3 is also provided with a colloidal gold lamp plate 34, which is fixed to the immunoassay fixing plate by copper studs 33, and is used to provide the necessary light source for the immunoassay module 3.

[0054] In this embodiment, as Figure 2 and Figure 3As shown, the base plate module also includes a drive module 7. Preferably, the drive module 7 is electrically connected to the main control board module 5 to automatically drive the reagent plate module 2 to slide along the guide rail 111. The output end of the drive module 7 is connected to the reagent plate module 2 to drive the reagent plate module 2 to slide on the base plate module. The base module 1 also includes two guide rails 111, which are spaced apart on the base module 1 to provide a more stable and accurate positioning and guiding function for the reagent plate module 2, effectively avoiding instability or deviation, or the possibility of sliding off the guide rail, that may occur when the reagent plate module 2 performs reciprocating linear motion on the guide rail 111. Preferably, the drive module 7 includes a lead screw motor 71 and a lead screw 72. The lead screw motor 71 is fixed to the base plate module by a motor fixing component, and the output end of the lead screw motor 71 is connected to the lead screw 72. The lead screw 72 is fixed to the reagent plate module 2 by a lead screw 72 fixing component. Driven by the lever motor 71, the lead screw 72 drives the reagent plate module 2 to reciprocate linearly along the guide rail 111; the base module 1 is also equipped with an optocoupler sensor, which is located on one side of the guide rail 111; the reagent plate module 2 is equipped with an optocoupler light-blocking plate; the optocoupler sensor, as a position feedback element, detects the trigger signal of the optocoupler light-blocking plate on the reagent plate module 2 to achieve hard protection of the travel limit and origin calibration, eliminating cumulative errors; in coordination with the lead screw motor 71 and the lead screw 72, and with the guidance of the guide rail 111, the precise and automated motion control of the reagent plate module 2 is realized, ensuring the precise stopping of the reagent plate between the detection stations.

[0055] In this embodiment, there are two reagent slots 21; the driving module 7 drives the reagent plate assembly to slide, so that the two reagent slots 21 move closer or further away from the corresponding insertion port 121 at the same time, so that the reagent plate module 2 is in the detection position or loading / unloading position, thereby realizing the physical separation of the immune detection area and the blood routine area, and avoiding blood sample contamination of the optical components. It should be clear that the two reagent card slots 21 are the first fluorescence slot and the second reagent slot, respectively. The socket 121 corresponding to the first fluorescence slot is the first socket, and the socket 121 corresponding to the second reagent slot is the second socket. In the detection position, the first fluorescence slot is aligned with the first socket to form the first detection channel, and the second reagent slot is aligned with the second socket to form the second detection channel. At this time, both the first fluorescence slot and the second reagent slot are completely contained within the base module 1, and both have a certain distance from the first and second sockets, so that the reagent cards in the dual detection channels are in the detection position. In the loading and unloading position, the first fluorescence slot and the second reagent slot are at least partially exposed in the corresponding sockets 121. At this time, the reagent cards in the first fluorescence slot and the second reagent slot can be replaced, or the test reagent card can be placed into the slot for corresponding detection.

[0056] In this embodiment, the width of the first fluorescence groove is smaller than the width of the second reagent groove, and the width of the first socket 121 is smaller than the width of the second socket, that is, the width of the first detection channel is smaller than the width of the second detection channel; specifically, the first detection channel (immunoassay only): insert reagent card → slide to detection position → fluorescence detection and colloidal gold detection (immunoassay) → the main control board module 5 directly outputs the results; the second detection channel (immunoassay + blood routine): insert reagent card → immunoassay → slide the second reagent groove to the blood routine area → the microscope camera module 4 takes pictures of the detection → the main control board module 5 analyzes the comprehensive results. In other words, the first detection channel only performs immunoassays (fluorescence and colloidal gold detection) and does not need to move to other areas. Therefore, it is set as a narrow channel (small width) to reduce stray light interference, improve the fluorescence signal-to-noise ratio, and thus improve optical detection accuracy. The second detection channel is mainly for immunoassays and routine blood tests. It needs to be driven to the microscope camera module 4 for related routine blood tests. Therefore, it is set as a wide channel (large width) to accommodate blood sample loading, i.e., to accommodate the blood sample diffusion area and reserve space for the microscope camera module 4 to capture blood cell morphology from multiple angles to achieve routine blood tests. In addition, if only routine blood tests are needed, the corresponding routine blood tests can be performed directly in the second detection channel.

[0057] It is clear that in the first detection channel, only fluorescence detection and colloidal gold detection are performed on the reagent card, that is, only the immunoassay of the reagent card is realized; in the second detection channel, after the corresponding immunoassay is performed on the reagent card, the reagent card can continue to slide into the blood routine detection area under the drive of the reagent plate module 2. At this time, the microscope camera module 4 takes pictures of the reagent card to realize the blood routine detection.

[0058] In this embodiment, as Figures 1 to 4 As shown, the reagent plate module 2 is provided with a first limiting member 23, and the base module 1 is provided with a second limiting member (not shown) at a corresponding position. When the first limiting member 23 and the second limiting member cooperate with each other, the two reagent card slots 21 are partially exposed outside the corresponding insertion port 121, which limits the sliding stroke of the reagent plate module 2, that is, prevents the entire reagent plate module 2 from being exposed, so as to replace or place reagent cards. Among them, the first limiting member 23 is a groove, and the second limiting member is a protrusion that matches the shape of the groove. It is worth noting that the design of the limiting structure is not limited to the above-mentioned groove and protrusion cooperation method, and also includes other possible structural designs to achieve similar functions and effects.

[0059] In this embodiment, the reagent card slot 21 includes an integrally connected guide portion 211 and a receiving portion 212. The diameter of the guide portion 211 is larger than the diameter of the receiving portion 212, and the length of the guide portion 211 is smaller than the length of the receiving portion 212. The guide portion 211 guides the insertion of the reagent card, while the receiving portion 212 accommodates the reagent card that enters through the guide portion 211, ensuring the reagent card remains stable during testing, thereby improving the accuracy and reliability of the test. Furthermore, the larger diameter of the guide portion 211 compared to the receiving portion 212 facilitates the smooth entry of the reagent card into the receiving portion 212 and ensures the reagent card is securely fixed within the receiving portion 212, preventing unnecessary movement or tilting during testing and further guaranteeing the accuracy of the test results.

[0060] In this embodiment, as Figure 3 and Figure 4 As shown, the reagent card slot 21 is equipped with multiple spring clips 22, which are spaced apart along the sliding direction of the reagent plate module 2 to form multi-point elastic pressure, firmly fixing the reagent card in the slot and preventing it from shifting or loosening during transportation, sliding, or testing. Preferably, the spring clip 22 can be made of elastic material to accommodate slightly different reagent card thicknesses, providing uniform clamping force through deformation, avoiding damage to the card due to excessive tightness or poor contact due to excessive looseness. That is, after the reagent card is fixed, its detection area (such as the reaction line) is precisely aligned with the optical path or electrode of the immunoassay module 3 and the imaging focus of the microscope camera module 4, reducing signal errors caused by positional deviations. In addition, the user only needs to insert the reagent card into the slot, and the spring clip 22 automatically clamps, eliminating the need for manual adjustment of the locking device, shortening operation time and reducing the risk of human error.

[0061] In this embodiment, as Figure 1 and Figure 2 As shown, the system also includes a reduction gearbox module 8 located on the base module 1, with its output connected to the microscope camera module 4. The reduction gearbox module 8 adjusts the microscope camera module 4 to ensure higher stability and prevent vibration during detection. Furthermore, the reduction gearbox module 8 allows the microscope camera module 4 to reciprocate vertically, aligning it with the reagent card in the reagent card slot 21. This means the microscope camera module 4, under the adjustment of the reduction gearbox module 8, continuously images the reagent card, improving the positioning accuracy of the reagent card detection and increasing the overall accuracy of the detection.

[0062] In this embodiment, as Figures 7 to 9As shown, the gearbox module 8 includes a gearbox fixing component 85, a gearbox assembly 82, a motor, and upper and lower gearbox fixing plates 84. The gearbox fixing component 85 is located on the base module 1; the gearbox assembly 82 is located on the gearbox fixing component 85; the output end of the motor is connected to the gearbox assembly 82; and the upper and lower gearbox fixing plates 84 are located on the periphery of the gearbox assembly 82. Preferably, the motor is a stepper motor 81. Driven by the stepper motor 81, the microscope camera module 4 moves up and down through the gearbox fixing component 85 to achieve precise positioning of the reagent card in the reagent card slot 21. Preferably, the gearbox module 8 is a gearbox reducer. This application reduces the volume ratio of the structure by structuring the gearbox reducer, simplifying the volume structure of the portable multifunctional analyzer, reducing space occupancy, and improving its portability.

[0063] In this embodiment, as Figure 9 As shown, the microscope camera module 4 includes a helical rack 42 and a helical pin 43. The helical rack 42 is located on the side of the microscope camera module 4 near the gearbox module 8. The helical pin 43 is located on the side wall of the gearbox assembly 82 near the microscope camera module 4. The helical rack 42 and the helical pin 43 mesh, connecting the microscope camera module 4 to the gearbox module 8, thereby locking the microscope camera module 4 onto the gearbox module 8. Furthermore, the gearbox module 8 is typically used to adjust the focusing mechanism of the microscope camera, specifically to drive the lens to move up and down. The helical rack 42 and the helical pin 43 smoothly transmit the power output from the gearbox module 8 to the microscope camera module 4 through helical gear meshing, avoiding the impact vibration that may occur with straight gear meshing, ensuring the smoothness of the focusing process, and improving repeatability accuracy. Furthermore, the lateral meshing design of the helical rack 42 and the helical pin 43 can save longitudinal space inside the device, allowing the microscope camera module 4 to be closer to the reagent slot 21 (shortening the object distance), while leaving enough space to arrange the light source or other sensors.

[0064] In this embodiment, as Figures 7 to 9As shown, the microscope camera module 4 also includes two microscope camera assemblies 41 arranged side by side. This side-by-side design saves lateral space and allows the module to fit the size limitations of portable devices. Each microscope camera assembly 41 includes a lens, a microscope tube 412, and an adapter ring 411. The microscope tube 412 is connected to the lens; the adapter ring 411 is connected to the microscope tube 412. Specifically, in this application, the two microscope camera assemblies 41 are a low-power microscope assembly and a high-power microscope assembly. The low-power microscope assembly and the high-power microscope assembly are mounted on the optical fixing plate 87 via a microscope clamping plate 83. The clamping plate 83 and the optical fixing plate 87 are used to fix the two camera components with rigid materials to ensure the parallelism of their optical axes and avoid the need for recalibration when switching magnifications. The optical fixing plate 87 is set on the gearbox fixing member 85 through the optical coupler baffle 88, and the gearbox fixing member 85 is provided with an optical coupler through the optical coupler fixing member 86. The optical coupler converts the light signal captured by the camera into an electrical signal, which is processed by the main control board module 5. The baffle prevents stray light interference and improves the signal-to-noise ratio to assist the microscope camera assembly 41 in capturing images, so that the captured information can be transmitted to the main control board module 5 in the form of an optical signal.

[0065] In this embodiment, as Figure 1 As shown, the system also includes a battery compartment 6, which is located on the base module 1 and electrically connected to the main control board module 5. The battery compartment 6 serves as a built-in power source, supporting rapid start-up detection, eliminating the need for power connection, shortening response time, and allowing the analyzer to operate independently in environments without external power, such as in the field, emergency rooms, and mobile medical scenarios. This significantly expands its application scenarios and improves device portability. Furthermore, the battery compartment 6 is integrated with the base module 1 via a circuit board, without adding extra volume, maintaining the device's lightweight and compact design, meeting the design requirements of portable instruments.

[0066] In this embodiment, a light panel assembly 9 is also included. The light panel assembly 9 is disposed on the side of the base module 1 near the microscope camera assembly 41 and below the reagent plate module 2 to assist in imaging and ensure the clarity of the images captured by the microscope camera module 4. The light panel assembly 9, located below the reagent plate module 2, projects uniform light upwards, penetrating the translucent reagent card, eliminating shadows or reflections, and ensuring that the microscope camera module 4 captures a clear reaction area.

[0067] In this embodiment, as Figure 1As shown, the base module 1 includes a base plate assembly 11 and a bottom shell assembly 12. The base plate assembly 11 is detachably disposed within the bottom shell assembly 12. Preferably, the base plate assembly 11 is fixed within the bottom shell assembly 12 by means of buckles, screws, or slide rails. The guide rail 111 is disposed on the base plate assembly 11 so that the reagent plate module 2 slides on the guide rail 111. The insertion port 121 is disposed on the side wall of the bottom shell assembly 12, and the sliding reagent plate module 2 aligns the insertion port 121 with the reagent slot 21. The base plate assembly 11 serves as a support platform, fixing core components such as the reagent plate module 2, the immunodetection module 3, the microscope camera module 4, and the main control board module 5, ensuring accurate positioning of each module, such as the alignment of the reagent slot 21 with the immunodetection component 32. The bottom shell assembly 12 serves as an external frame, providing mechanical support and physical protection to protect internal precision components, such as the main control board module 5 and the microscope camera module 4.
