Description

Technical Field

[0001] This utility model relates to the field of medical testing equipment technology, and in particular to an optical testing module and a blood lipid analyzer with the module. Background Technology

[0002] A blood lipid analyzer is a medical device used to detect lipid components in the blood. It can measure indicators such as total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C, i.e. "good" cholesterol), and low-density lipoprotein cholesterol (LDL-C, i.e. "bad" cholesterol), providing data support for cardiovascular disease risk assessment and health management.

[0003] The optimal operating temperature for a lipid analyzer is 20-35℃. Operating outside this range can lead to decreased enzyme activity or sample denaturation, causing deviations in indicators such as TC and TG. Some photosensitive reagents (such as enzyme-linked immunosorbent assay reagents) are easily decomposed under strong light, resulting in absorbance detection errors. Furthermore, in the optical detection module, fluctuations in light source intensity directly affect the stability of colorimetric results. Therefore, changes in temperature and light intensity can significantly impact lipid testing, and current lipid analyzers cannot effectively mitigate these interferences during the testing process.

[0004] In view of this, the present invention provides a new solution to the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an optical detection module and a blood lipid analyzer with the module, which solves the problem of inaccurate blood lipid detection results caused by environmental temperature fluctuations and light interference.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

The outer surfaces of the first cover plate, the second cover plate, and the third cover plate are all covered with a light-absorbing coating.

[0010] A further preferred embodiment is that the third cover plate is provided with a limiting groove adapted to the heating device on the side near the second cover plate, and the heating device is placed in the limiting groove.

[0015] A further preferred embodiment is that the first cover plate, the second cover plate, and the third cover plate are detachably connected by screws.

[0016] A further preferred embodiment is that the heating device is a semiconductor heating plate.

[0021] A further preferred embodiment is that the test chamber is provided with a pick-up and drop-off port, and the pick-up and drop-off port is provided with an outer cover for sealing the test chamber.

[0022] In summary, this utility model has the following beneficial effects:

[0023] The optical detection module of this utility model includes: a heating device for stabilizing the test environment of the test strip; a first cover plate, a second cover plate, and a third cover plate stacked together, wherein the second cover plate is provided with a slot for positioning the test strip, and the outer surfaces of the first cover plate, the second cover plate, and the third cover plate are all covered with a light-absorbing coating.

[0024] This invention utilizes a heating device to heat the optical detection module and test strips, effectively maintaining the stability of the test strip's temperature. A stable test temperature is crucial for blood lipid testing, ensuring the accuracy of various chemical reactions and optical detection indicators during the process.

Therefore, this invention solves the problem of inaccurate blood lipid test results caused by environmental temperature fluctuations and light interference. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example: An optical detection module and a blood lipid analyzer incorporating the module, such as... Figure 1-3As shown, the optical detection module includes a heating device 4, a carrier plate 5, and a first cover plate 1, a second cover plate 2, and a third cover plate 3 stacked together. The first cover plate 1, the second cover plate 2, and the third cover plate 3 are all detachably connected, and the outer surfaces of the first cover plate 1, the second cover plate 2, and the third cover plate 3 are all covered with a light-absorbing coating.

[0033] The heating device 4 can stabilize the testing environment of the test strip 12 by heating. Specifically, the heating device 4 is used to heat the optical detection module and the test strip 12 to maintain the stability of the test temperature of the test strip 12. Preferably, the heating device 4 is a semiconductor heating plate.

[0034] In the above technical solution, by setting a heating device 4 (such as a semiconductor heating plate) to heat the optical detection module and the test strip 12, the stability of the test temperature of the test strip 12 can be effectively maintained. A stable test temperature is of great significance for blood lipid testing. It ensures the accuracy of various chemical reactions and optical detection-related indicators during the testing process, avoids deviations in test results due to temperature fluctuations, and ensures that each test is conducted under relatively consistent and suitable temperature conditions, thereby improving the reliability and accuracy of blood lipid test results.

[0035] Preferably, the first cover plate 1, the second cover plate 2 and the third cover plate 3 are connected by screws 6 to make the overall connection strength of the optical detection module high and the disassembly and assembly more convenient.

[0036] In the above technical solution, the first cover plate 1, the second cover plate 2, and the third cover plate 3 are detachably connected, which facilitates maintenance, component replacement, or cleaning of the module during use. For example, when an internal component malfunctions and needs repair, the corresponding cover plate can be easily removed to quickly locate and resolve the problem, reducing time costs and inconvenience caused by maintenance operations and improving the maintainability and service life of the entire optical inspection module.

[0037] Preferably, the light-absorbing coating is a matte black paint.

[0038] In the above technical solution, the material surface is sprayed with a light-absorbing color (black) primarily to reduce the impact of light on the test. The first cover plate 1, the second cover plate 2, and the third cover plate 3 are sequentially fastened together, and all three surfaces are sprayed with a light-absorbing color. This three-layer matte black paint coating effectively eliminates stray light interference in the testing environment, improving the signal-to-noise ratio of absorbance detection. During blood lipid testing, the optical path within the optical detection module needs to be kept as stable and pure as possible. The light-absorbing coating absorbs excess stray light, making the light signal used for detection more accurate, thereby improving the precision of optical detection and ensuring that the final output of the blood lipid analyzer is more accurate and reliable.

[0039] Preferably, the first cover plate 1, the second cover plate 2, and the third cover plate 3 are all made of materials with good thermal conductivity, so that the temperature in the optical detection module is more stable and uniform.

[0040] Specifically, the first cover plate 1, the second cover plate 2, and the third cover plate 3 are all made of aluminum alloy.

[0041] In the above technical solution, aluminum alloy has good thermal conductivity, which can quickly conduct the heat generated by heating device 4 to the entire optical detection module to rapidly heat the test strip 12, so that the sample and detection environment are kept in a relatively stable temperature range, ensuring that the optical detection module can maintain stable performance under different environmental conditions, and reducing the negative impact of temperature fluctuations on the accuracy and stability of optical detection.

[0042] The aluminum alloy cover plate can evenly conduct heat, resulting in a more uniform temperature distribution inside the optical inspection module. During the inspection process, the heat from each component of the optical inspection module can be quickly and evenly dissipated through the first cover plate 1, the second cover plate 2, and the third cover plate 3, preventing localized overheating and thus improving the overall performance consistency of the optical inspection module. Uniform temperature distribution helps reduce thermal stress on optical components caused by localized temperature differences, extending the lifespan of optical components. It also improves the accuracy and reliability of optical inspection, ensuring the stability and repeatability of the inspection results.

[0043] Reference Figure 1-3 The second cover plate 2 has a slot 7 for positioning the test strip 12 on the side near the first cover plate 1. During testing, the test strip 12 can be inserted into the slot 7. The third cover plate 3 has a limiting groove 10 and a receiving groove 11 on the side near the second cover plate 2. The limiting groove 10 is adapted to the heating device 4, and the heating device 4 is placed in the limiting groove 10. The receiving groove 11 is adapted to the carrier 5, and the carrier 5 is placed in the receiving groove 11. Both the slot 7 and the receiving groove 11 have light-transmitting holes at the bottom. The carrier 5 is located between the back of the receiving groove 11 and the slot 7. The carrier 5 is installed on the third cover plate 3, and its main function is to allow light to pass through and reduce the entry of dust, foreign objects, etc. into the optical detection module.

[0044] To avoid obstructing the light path, preferably, the first cover plate 1 has a first opening corresponding to the position of the slot 7, so that the slot 7 is exposed for easy insertion of the test strip 12. The heating device 4 has a second opening corresponding to the position of the receiving groove 11.

[0045] In the above technical solution, the heating device 4 and the carrier plate 5 are respectively limited and fixed by the limiting groove 10 and the receiving groove 11, which will not cause damage to the heating device 4 and the carrier plate 5. When the screws 6 on the first cover plate 1, the second cover plate 2 and the third cover plate 3 are removed, the heating device 4 and the carrier plate 5 will be exposed naturally. The removal is simple and convenient, and it is easy to maintain and replace later.

[0046] A type of blood lipid analyzer, such as Figure 4 and 5 As shown, the system includes a lipid analyzer body 13 and an optical detection module. The lipid analyzer body 13 contains a testing chamber, and the optical detection module is configured to match the testing chamber, being detachably housed within it.

[0047] It is particularly worth mentioning that, in terms of the specific detachable connection method, the preferred method is to use screws 6 for fixing, so as to ensure that it can be easily installed and disassembled as needed.

[0048] Furthermore, a loading / unloading port 15 is provided above the test chamber. This port 15 connects to the outside environment, facilitating the insertion and removal of the optical detection module. To ensure the test chamber's airtightness during use and to prevent external interference such as light exposure, an outer cover 14 is fitted at the loading / unloading port 15. This outer cover 14 seals the test chamber. When the optical detection module needs to be operated, such as insertion or removal, the corresponding action is performed through the loading / unloading port 15. During the actual testing phase, the outer cover 14 remains firmly on the loading / unloading port 15, ensuring the stability of the testing environment.

[0049] In the above technical solution, the optical detection module is detachably installed in the testing chamber within the blood lipid analyzer body 13. This design greatly improves the ease of maintenance, effectively shortens maintenance time, and reduces maintenance costs. Specifically, screws 6 are used to achieve the detachable connection of the optical detection module, ensuring a stable and reliable connection. During normal use, this ensures the optical detection module is in the correct position, guaranteeing the accuracy and stability of the test data. Simultaneously, the screw 6 connection method facilitates installation and disassembly by operators following standard procedures, offering high operability and relatively lower requirements for operator skills. Furthermore, a loading / unloading port 15 and a matching outer cover 14 are provided above the testing chamber, providing a convenient passage for the optical detection module to enter and exit. When installing or removing the optical detection module, operators can easily complete the corresponding operations through the loading / unloading port 15. The reasonable design of the loading / unloading port 15 optimizes the operation process and improves work efficiency. The outer cover 14 covers the loading and unloading port 15 during testing, which can avoid light interference and effectively isolate external dust, moisture and other impurities from entering the test chamber, creating a relatively clean and stable working environment for the optical detection module, avoiding the impact of external interference factors on the detection accuracy, and further ensuring the accuracy and reliability of blood lipid test results.
