Abstract
Description
Technical Field
[0001] This invention relates to the field of hematology equipment technology, specifically to a portable rapid hemoglobin concentration detection device. Background Technology
[0002] Hemoglobin (Hb) is the core protein in red blood cells responsible for transporting oxygen. Abnormal concentrations of Hb directly reflect the body's health status (such as anemia, polycythemia vera, etc.).
[0003] Hemoglobin concentration is a key indicator for diagnosing diseases such as iron deficiency anemia, megaloblastic anemia, and thalassemia. Currently, the Mission Hemoglobin Analyzer Plus Hb is commonly used to detect the hemoglobin concentration in a patient's blood. The Mission Hemoglobin Analyzer Plus Hb consists of a main unit, which is composed of an LCD screen, buttons, and a test strip holder. The test strip holder has a light window in the middle. The main unit has a built-in testing module. When a blood sample is dropped onto the sample reaction area of the test strip, the testing module calculates the concentration by detecting the color intensity of the hemoglobin after reacting with the test strip, based on the principle of light reflection.
[0004] In actual use, the test strips of the Mission Hemoglobin Analyzer Plus Hb are mounted on the test strip holder, relying solely on the slots on the holder to ensure that the test strips are positioned above the testing module. However, there is a gap between the test strips and the light window, which causes a vertical deviation between the sample area of the test strip and the light window. As a result, the testing module cannot completely detect the sample area on the test strip, leading to errors in the hemoglobin concentration detection value and reducing the accuracy of the test.
[0005] Therefore, this invention proposes a portable rapid hemoglobin concentration detection device to solve the above problems. Summary of the Invention
[0006] To address the aforementioned issues, this invention provides a portable rapid hemoglobin concentration detection device. By utilizing the pushing force when the test strip is inserted to move the wedge block upward and controlling the pressure plate downward via a lever, the gap between the test strip and the light window is eliminated, ensuring the integrity of the detection area and improving detection accuracy.
[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A portable rapid hemoglobin concentration detection device includes a hemoglobin analyzer. The hemoglobin analyzer is equipped with a display screen, a controller, and a support. A hollow convex rail is fixedly connected to the middle of the support along its length. A light window is opened in the middle of the hollow convex rail. A slot is provided on the side of the support near the display screen. The hollow convex rail extends into the slot and is fixedly connected to the inner wall of the slot. A spring is fixedly connected to the top wall of the slot. A wedge block is fixedly connected to the bottom end of the spring. The side of the wedge block near the inner wall of the slot slides against the inner wall of the slot. The inclined surface is lower on the side closer to the inner wall of the slot than on the other side. Symmetrically arranged L-shaped connecting rods are fixedly connected to the wedge block. The top of the horizontal part of the L-shaped connecting rod is at the same level as the top of the wedge block. The vertical parts of the two L-shaped connecting rods are located on both sides of the hollow convex rail. Pull rods are slidably fitted on both sides of the hollow convex rail along the height direction of the hollow convex rail. A pressure plate located above the hollow convex rail is fixedly connected on the side of the pull rods that are close to each other. The pressure plate is located between the light window and the end of the hollow convex rail. Each L-shaped connecting rod is equipped with a control component for controlling the up and down movement of the corresponding pressure plate to press the sample test paper.
[0008] The technical principle of the above solution is as follows: By inserting the test strip into the slot, the test strip applies a pushing force to the inclined surface of the wedge block. The inclined surface of the wedge block decomposes the pushing force into an upward pushing force on the wedge block. The wedge block moves upward and compresses the spring. The upward movement of the wedge block drives the L-shaped connecting rod to move upward synchronously. The upward movement of the L-shaped connecting rod drives the control component to apply a downward pulling force to the pull rod, causing the pull rod to slide downward. The pull rod drives the pressure plate to move downward synchronously and apply pressure to the test strip, pressing the test strip tightly onto the hollow convex rail, ensuring that the test strip fits against the light window.
[0009] The above approach has the following beneficial effects: 1. This solution uses a pressure plate to press the test strip firmly, eliminating the gap between the test strip and the light window, thus preventing the sample area of the test strip from deviating from the light window in the vertical direction due to the gap, and ensuring the integrity of the detection area; 2. This solution, by eliminating gaps, can completely detect the sample area of the test strip, reducing errors in hemoglobin concentration detection values caused by incomplete detection and improving the accuracy of test results.
[0010] Furthermore, each control component includes a lever. The top of the lever near the slot is hinged to the bottom of the vertical rod of the corresponding L-shaped connecting rod, and the top of the lever away from the slot is hinged to the bottom of the corresponding pull rod. Symmetrically arranged fixed seats are fixedly connected to the bracket, and each fixed seat is rotatably connected to the corresponding lever at 1 / 3 of the position near the slot.
[0011] Beneficial effects: The lever principle is used to achieve precise control of the pressure plate, ensuring that the pressure plate can stably and reliably press the sample test paper, thereby improving the mechanical stability and ease of operation of the device.
[0012] Furthermore, the surface of the wedge block and the surface on which the wedge block slides into contact with the inner wall of the slot are coated with polytetrafluoroethylene.
[0013] Beneficial effects: The polytetrafluoroethylene coating has a low coefficient of friction, which can reduce the friction between the wedge and the inner wall of the slot, making the sliding of the wedge smoother and improving the service life and operation of the device.
[0014] Furthermore, symmetrically arranged wedge-shaped baffles are fixedly connected to the hollow convex rail. The wedge-shaped baffles are all located inside the slot. The side of the wedge-shaped baffles that is close to each other is set as an inclined surface, and the distance between the inclined surfaces of the two wedge-shaped baffles is smaller on the side closer to the inner wall of the slot than on the other side.
[0015] Beneficial effects: The wedge-shaped baffle can guide and position the inserted sample test strip, ensuring that the test strip is accurately inserted into the preset position, further improving the alignment accuracy between the test strip and the light window.
[0016] Furthermore, a disinfection lamp is installed on the hollow convex rail at the edge of the light window, and the disinfection lamp is connected to the controller signal.
[0017] Beneficial effects: The disinfection lamp can disinfect the light window area before and after testing, effectively preventing cross-infection, improving the hygiene and safety of the device, and is suitable for multiple uses in medical environments.
[0018] Furthermore, the hemoglobin analyzer is equipped with a photoelectric module located below the light window. The photoelectric module is coaxially arranged with the light window and is used to emit light through the light window to illuminate the sample area of the sample test strip, and to receive the light transmitted through the sample area. The photoelectric module is connected to the controller signal.
[0019] Beneficial effects: Optical detection of the sample area is achieved through the photoelectric module, providing accurate optical signals for the calculation of hemoglobin concentration and ensuring the reliability of the detection results.
[0020] Furthermore, a displacement sensor is fixedly connected to the top of the wedge block, and the displacement sensor is connected to the controller signal.
[0021] Furthermore, the controller has a built-in alignment determination module, which includes a receiving unit and a comparison unit. The receiving unit is used to receive the displacement signal from the displacement sensor; The comparison unit is used to compare the displacement signal of the receiving unit with the preset displacement-detection area model, calculate the displacement deviation value between the current displacement and the standard displacement, and thus determine whether the sample area of the sample test strip is accurately aligned with the center of the light window.
[0022] Furthermore, the comparison unit includes a compensation curve model, which is obtained through experiments by mapping the error values between the actual hemoglobin concentration and the detected concentration under different effective monitoring area deviations.
[0023] Furthermore, the controller has a built-in sample detection compensation module, which is used to substitute the effective detection area deviation value obtained from the comparison unit into the compensation curve model, and after compensation, the complete sample concentration value is obtained and output to the display screen.
[0024] Beneficial effects: By monitoring the displacement changes of the wedge block in real time through a displacement sensor, the alignment judgment module of the controller compares the displacement signal with the preset displacement-detection area model to calculate the displacement deviation value to determine whether the sample area of the test strip is aligned with the center of the light window; the sample detection compensation module substitutes the effective detection area deviation value into the compensation curve model, compensates and corrects the detection result before outputting it; through precise displacement monitoring and deviation compensation, the accuracy of hemoglobin concentration detection is improved, and the problem of incomplete detection caused by the gap between the test strip and the light window in traditional devices is solved.
[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0031] The following detailed description illustrates the specific implementation method: Example 1:
[0032] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown: A portable rapid hemoglobin concentration detection device includes a hemoglobin analyzer 1, a display screen 2, a controller, and a support 3. The display screen 2 is connected to the controller via signal. The preferred models of the display screen 2 and the controller are Innolux AT070TN92 and STMicroelectronics STM32F407VGT6, respectively. A hollow convex rail 4 is integrally formed along the length of the support 3, and a light window 5 is opened in the middle of the hollow convex rail 4. The existing Mission hemoglobin analyzer 1 Plus Hb test strip is mounted on the support 3, relying solely on the slot 6 on the support 3 to ensure that the test strip is positioned above the test module. However, the test strip and the light window 5 are not properly fitted, resulting in a gap. This gap causes a vertical deviation between the sample area of the test strip and the light window 5, leading to an incomplete sample area and reduced detection accuracy. To improve the accuracy of hemoglobin concentration detection, as shown in the attached document... Figure 4 and attached Figure 5 As shown, the bracket 3 has a slot 6 near the display screen 2. A hollow convex rail 4 extends into the slot 6 and is integrally formed with the inner wall of the slot 6. A spring 7 is fixedly connected to the top wall of the slot 6 by adhesive. A wedge block 8 is welded to the bottom end of the spring 7. The side of the wedge block 8 near the inner wall of the slot 6 slides with the inner wall of the slot 6 through a slide rail and a slide groove. The surface of the wedge block 8 and the surface of the wedge block 8 that slides with the inner wall of the slot 6 are coated with polytetrafluoroethylene. The inclined surface of the wedge block 8 is lower on the side near the inner wall of the slot 6 than on the other side. Symmetrically arranged L-shaped grooves are welded on the wedge block 8. The top of the horizontal section of the L-shaped connecting rod 9 is at the same horizontal plane as the top of the wedge block 8. The vertical sections of the two L-shaped connecting rods 9 are located on both sides of the hollow convex rail 4. Both sides of the hollow convex rail 4 are slidably fitted with pull rods 10 along the height direction of the hollow convex rail 4 via slide rails and slide grooves. On the side of the pull rods 10 that are close to each other, there is a pressure plate 11 welded above the hollow convex rail 4. The pressure plate 11 is located between the light window 5 and the end of the hollow convex rail 4. Each L-shaped connecting rod 9 is equipped with a control component for controlling the up and down movement of the corresponding pressure plate 11 to press the sample test paper, as shown in the attached figure. Figure 4 As shown, each control component includes a lever 12. The top of the lever 12 near the slot 6 is hinged to the bottom of the vertical rod of the corresponding L-shaped connecting rod 9. The top of the lever 12 away from the slot 6 is hinged to the bottom of the corresponding pull rod 10. The bracket 3 is fixedly connected with symmetrically arranged fixing seats 13 by adhesive. The fixing seats 13 are rotatably connected to the corresponding lever 12 at 1 / 3 of the side near the slot 6. By inserting the test strip, the lever 12 is driven to rotate around the fixing seat 13, which drives the pull rod 10 to move the pressure plate 11 downward in sync, pressing the test strip tightly onto the hollow convex rail 4 and fixing it, eliminating the gap between the test strip and the light window 5 in the vertical direction, so as to reduce the detection error. As attached Figure 2 As shown, the hemoglobin analyzer 1 is equipped with a photoelectric module 16 located below the light window 5. The photoelectric module 16 is coaxially arranged with the light window 5 and is used to emit light through the light window 5 to illuminate the sample area of the sample test strip and receive the light transmitted through the sample area. The photoelectric module 16 is connected to the controller signal and uses the principle of optical reflection to detect the concentration of hemoglobin in the blood.
[0033] The specific implementation process is as follows: When the user inserts the sample test strip into the slot 6 of the bracket 3, the test strip first contacts the inclined surface of the wedge block 8. Since the inclined surface of the wedge block 8 is lower on the side closer to the inner wall of the slot 6 than on the other side, the insertion force of the test strip will be decomposed into horizontal and vertical components by the inclined surface. The vertical component pushes the wedge block 8 to slide upward along the inner wall of the slot 6. During this process, the spring 7 is compressed. As the wedge block 8 moves upward, the symmetrical L-shaped connecting rod 9 on the wedge block 8 moves upward synchronously. The vertical rod of the L-shaped connecting rod 9 drives the lever 12, which is hinged at the bottom end, to move upward near the slot 6. The fixed seat 13 is located at 1 / 3 of the lever 12 near the slot 6. Using the principle of the lever 12, the upward movement of the L-shaped connecting rod 9 is amplified and transmitted to the pull rod 10. That is, when the L-shaped connecting rod 9 moves upward, the lever 12 rotates around the fixed seat 13. The end of the lever 12 away from the slot 6 pulls the pull rod 10 downward. The pull rod 10 slides along the height direction of the hollow convex rail 4, thereby driving the pressure plate 11 connected to the pull rod 10 to move downward synchronously. The pressure plate 11 is located between the light window 5 and the end of the hollow convex rail 4. The downward pressing action of the pressure plate 11 directly acts on the sample test strip, tightly adhering the test strip to the surface of the hollow convex rail 4. This eliminates the gap between the test strip and the light window 5, avoiding vertical deviation between the test strip and the light window 5. This ensures that the light emitted by the photoelectric module 16 below can completely illuminate the sample area and receive the transmitted light, avoiding incomplete detection area caused by the vertical gap between the test strip and the light window 5, which would lead to concentration calculation errors. At the same time, the entire mechanical transmission process is automatically triggered by the pushing force of the test strip insertion, requiring no additional operation and improving the convenience of the device. In addition, the photoelectric module 16 can obtain more accurate optical signals, reducing the error of the hemoglobin concentration value calculated by the controller based on this signal and improving the detection accuracy.
[0034] Example 2:
[0035] As attached Figure 5 As shown, the difference from Embodiment 1 is that symmetrically arranged wedge-shaped baffles 14 are fixedly connected to the hollow convex rail 4. The wedge-shaped baffles 14 are all located inside the slot 6. The sides of the wedge-shaped baffles 14 that are close to each other are set as inclined surfaces, and the distance between the inclined surfaces of the two wedge-shaped baffles 14 is smaller on the side closer to the inner wall of the slot 6 than on the other side. Through the guidance of the inclined surfaces of the wedge-shaped baffles 14, it is ensured that the test strip is located in the center of the hollow guide rail after insertion, which further improves the accuracy of the alignment between the test strip sample area and the light window 5, thereby improving the detection accuracy.
[0036] Example 3:
[0037] As attached Figure 1 As shown, the difference from Example 2 is that, in order to reduce the interference of external bacteria and residual bacteria on the hemoglobin analyzer 1 during the detection process, a disinfection lamp is provided on the hollow convex rail 4 at the edge of the light window 5. The disinfection lamp is preferably a Seoul Semiconductor SUC30 series UV-C LED. The disinfection lamp is connected to the controller signal, and the controller controls the disinfection lamp to disinfect and sterilize the sample detection area before and after the detection, thereby reducing the bacteria on the detection of hemoglobin and improving the accuracy of hemoglobin concentration detection.
[0038] Example 4:
[0039] As attached Figure 1 and attached Figure 4 As shown, the difference from embodiment 3 is that a displacement sensor 15 is welded to the top of the wedge block 8. The displacement sensor 15 is preferably a KTC-100 and is connected to the controller signal. The controller has a built-in alignment determination module, which includes a receiving unit and a comparison unit. A receiving unit is used to receive the displacement signal from the displacement sensor 15; The comparison unit is used to compare the displacement signal of the receiving unit with the preset displacement amount-detection area model, calculate the displacement deviation value between the current displacement amount and the standard displacement amount, and thus determine whether the sample area of the sample test paper is accurately aligned with the center of the light window 5. Displacement-detection area model calculation process: 1. Experimental Data Acquisition: Through multiple experiments, the alignment area (effective detection area) between the test paper sample area and the light window 5 was measured under different displacement amounts (the upward movement distance of wedge block 8). For example: When the displacement is 0mm (no test paper is inserted), the effective detection area is 0. When the displacement is 5mm (standard insertion depth), the effective detection area is the total area of window 5 (e.g., 10mm × 10mm = 100mm²). When the displacement is 4mm, the effective detection area is 80mm² (assuming the sample area only covers 80% of the light window). 2. Model Establishment: The collected displacement x and effective detection area y data are fitted to obtain the mapping relationship; for example, the formula is obtained through linear regression: y=kx+b (where k is the slope and b is the intercept); assuming that the experimental data fits to obtain y=20x (that is, for every 1mm increase in displacement, the effective detection area increases by 20mm²). 3. Deviation Calculation: The comparison unit substitutes the current displacement x1 into the model to obtain the theoretical effective detection area y1, and compares it with the standard displacement x0 (e.g., 5mm) and the corresponding standard effective detection area y0 (100mm²), and calculates the deviation value: Δy = y0 - y1; if Δy > 0, it means that the sample area is not completely aligned with the light window 5. The comparison unit includes a compensation curve model, which is obtained through experiments by mapping the error values between the actual hemoglobin concentration and the detected concentration under different effective monitoring area deviations. The controller has a built-in sample detection compensation module, which is used to substitute the effective detection area deviation value obtained from the comparison unit into the compensation curve model, and after compensation, the complete sample concentration value is obtained and output to the display screen 2. Methods for establishing compensation curve models: 1. Error Data Acquisition: Under different effective detection area deviations Δy, measure the error value ΔC between the actual hemoglobin concentration (obtained through gold standard methods such as biochemical analyzers) and the concentration detected by the device. For example: When Δy = 0 (perfect alignment), ΔC = 0; When Δy = 20 mm² (effective detection area reduced by 20%), ΔC = -5 g / L (detection value is 5 g / L lower). When Δy = 40 mm², ΔC = -10 g / L.
[0040] 2. Curve Fitting: The collected Δy and ΔC data are fitted to a curve to establish a compensation curve model. For example, a polynomial fitting yields the formula: ΔC = aΔy + bΔy² + c (where a, b, and c are fitting coefficients). Assume that after fitting the experimental data, ΔC = -0.25Δy (meaning that for every 1 mm² reduction in the effective detection area, the detection value is 0.25 g / L lower).
[0041] 3. Compensation Calculation: The compensation module substitutes the current Δy into the model to obtain the compensation value (ΔCcomplement), and then adds it to the original detected concentration (Coriginal) to obtain the final compensated concentration: Ccomplement = Coriginal + ΔCcomplement. For example, if Coriginal = 110 g / L and Δy = 20 mm², then ΔCcomplement = 5 g / L and Ccomplement = 115 g / L.
[0042] The specific implementation process is as follows: When the user inserts the test strip, the wedge block 8 moves upward, and the displacement sensor 15 collects the displacement amount in real time (e.g., x1=4.5mm). The receiving unit transmits the displacement signal to the comparison unit. The comparison unit substitutes the displacement amount-detection area model: y1=20×4.5=90mm², the standard effective detection area y0=100mm², and calculates the deviation value Δy=10mm². Subsequently, the compensation module substitutes the compensation curve model: ΔCcomplement=0.25×10=2.5g / L. If the original detection concentration Coriginal=120g / L, then the compensated concentration Ccomplement=120+2.5=122.5g / L. The final result is output to the display screen 2.
[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
