Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of medical devices, and more particularly to a multi-channel blood lipid detection device. Background Art

[0002] Currently, blood lipid detection devices generally perform single-channel detection, that is, a blood sample is detected at one detection position, which limits the flexibility and efficiency of detection. Since all detection items need to be completed at the same position, multiple detection operations cannot be performed simultaneously, and the number of detection items is also limited.

[0003] In addition, the flow distance of the blood sample in existing blood lipid detection devices is limited and cannot reach different detection modules. Due to the short flow distance, the blood lipid detection device cannot accommodate multiple detection modules or complex detection processes.

[0004] Blood lipid detection devices are relatively single in function and cannot meet various blood lipid detection needs. For example, it is impossible to simultaneously detect multiple items such as total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C).

[0005] Therefore, single-channel blood lipid detection devices are suitable for simple and low-cost detection scenarios, but their limitations will be more obvious in occasions that require high-throughput and multi-functional detection. Summary of the Invention

[0022] In some alternative embodiments, the reflection hole 41 is a round hole with a curved surface.

[0023] In some alternative embodiments, the lamp bead 51 is an LED red light lamp.

[0024] In a second aspect, an embodiment of the present disclosure provides a sample detection method, which is applied to the multi-channel blood lipid detection device described in any implementation manner of the first aspect.

[0040] The following refers to Figure 1 and Figure 2 , where Figure 1 is a three-dimensional schematic diagram of an embodiment of a multi-channel blood lipid detection device according to this disclosure.

[0041] As Figure 1 and Figure 2 shown, the multi-channel blood lipid detection device includes a detection cover plate 3, a detection middle frame 4, a light-transmitting sheet 2, a detection base 1, and a detection circuit board 5, which are arranged in sequence from top to bottom.

[0042] Among them, the detection base 1, the detection middle frame 4, the detection cover plate 3, and the light-transmitting sheet 2 are functional parts. The detection base 1, the detection middle frame 4, and the detection cover plate 3 are also support parts at the same time. The support parts provide a positioning reference and structural support for the functional parts, and complete the assembly and installation of each functional part.

[0043] The detection cover plate 3 is used to guide and limit the fixation of the reagent kit. During detection, the reagent kit needs to be placed inside the detection cover plate 3 and be limited by the detection cover plate 3.

[0044] It should be noted that here, at least one test strip can be arranged in the reagent kit. The number and arrangement of the detection holes in different test strips can be the same or different. It can be understood that the arrangement of the test strips in the reagent kit, as well as the arrangement of the detection holes in each test strip, can be set accordingly according to the arrangement of the functional parts in the multi-channel blood lipid detection device.

[0045] For example, asFigure 1 As shown, there are two test strips 61 in the kit. Each test strip 61 has three detection holes, and the centers of the six detection holes are located on the same straight line. The three detection holes in the test strip 61 can be used to detect three different blood lipid detection items respectively. For example, it can include a cholesterol detection hole, a triglyceride detection hole, and a high-density lipoprotein cholesterol detection hole. Among them, the cholesterol detection hole is used to detect the content of total cholesterol (TC) in the blood, the triglyceride detection hole is used to detect the content of triglyceride (TG) in the blood, and the high-density lipoprotein cholesterol detection hole: is used to detect the content of high-density lipoprotein cholesterol (HDL-C) in the blood.

[0046] Here, the detection cover plate 3 guiding and positioning the kit means that after the kit reaches the position of the detection cover plate 3, the kit and the detection cover plate 3 guide and position each other to enable each test strip in the kit to be located at the designated position respectively, so as to complete the blood lipid detection of multiple channels subsequently.

[0047] Specifically, as Figure 1 and Figure 2 shown, the detection cover plate 3 is integrally designed, and the kit can be placed in a limited and fixed manner in the internal space surrounded by the detection cover plate 3. Optionally, one end of the detection cover plate 3 can be designed to be open, so that the kit can enter the detection cover plate 3 from the above opening to start detection and leave the detection cover plate 3 after the detection is completed.

[0048] The detection cover plate 3 itself is light-tight (for example, black) to ensure the accuracy of the light transmission path during the photoelectric detection process.

[0049] A detection middle frame 4 is fixedly arranged below the detection cover plate 3 to ensure the fixed position between the detection cover plate 3 and the detection middle frame 4 without movement, thereby ensuring the accurate alignment of the light transmission path during the photoelectric detection process. For example, the detection cover plate 3 and the detection middle frame 4 can be fixed by ultrasonic welding.

[0050] The detection middle frame 4 is used to reflect the reflected light emitted from each detection hole in the test strip in the kit limited and fixed by the detection cover plate 3 above to the detection base 1 below. For example, the reflected light emitted after the color reaction between the blood in the detection hole and the red light can be reflected to the detection base 1 below.

[0051] Specifically, at least one reflection hole 41 is provided in the detection middle frame 4. The reflection holes 41 in the detection middle frame 4 correspond one by one to each detection hole in the test strip in the kit limited and fixed by the detection cover plate 3, and each reflection hole 41 is used to reflect the reflected light emitted from the corresponding detection hole.

[0052] Optionally, the reflection hole 41 can be a round hole plus a curved surface, and this design can achieve technical effects including but not limited to the following:

[0053] By using a round hole as the aperture diaphragm, stray light (such as ambient light or scattered light from non-detection holes) can be restricted from passing through the reflection hole 41 and finally entering the photocell 52, thereby reducing background noise and improving the signal-to-noise ratio (SNR).

[0054] In addition, through a curved surface design such as a concave surface or a parabolic surface, the diffuse reflection light in the color reaction area (i.e., the detection hole) can be efficiently converged to the reflection hole 41 and finally reach the photocell 52, enhancing the effective signal intensity.

[0055] It can be understood that other parts of the detection middle frame 4 except the reflection hole 41 are light-tight.

[0056] The light-transmitting sheet 2 is arranged below the detection middle frame 4. The light-transmitting sheet 2 is a full-spectrum light-transmitting sheet. It can be understood that when the multi-channel blood lipid detection device is not provided with a reagent kit, the internal space of the detection cover plate 3 is a cavity, and the detection middle frame 4 is exposed from above the internal cavity of the detection cover plate 3, that is, the detection middle frame 4 and the reflection hole 41 can be seen, and the light-transmitting sheet 2 below can be seen through the reflection hole 41.

[0057] The detection base 1 is arranged below the light-transmitting sheet 2 and is used to limit the light-transmitting sheet 2. Specifically, a groove can be arranged on the upper surface of the detection base 1, and the light-transmitting sheet 2 can be placed in the above groove to limit the light-transmitting sheet 2.

[0058] The detection base 1 is also provided with at least one light-transmitting hole 11 and at least one receiving hole 12. Among them, at least one receiving hole 12 corresponds one-to-one with at least one reflection hole 41 in the upper detection middle frame 4, and each receiving hole 12 is used to receive the reflected light reflected by the corresponding reflection hole 41 above.

[0059] Optionally, the receiving hole 12 adopts a square plus chamfers on both sides design, which can achieve the following technical effects including but not limited to:

[0060] First of all, since the photosensitive area of the photocell is usually rectangular (such as a silicon photodiode chip), the shape of the square receiving hole matches its height, which can reduce the ineffective light-transmitting area and improve the light energy utilization rate.

[0061] Secondly, the chamfers on both sides can avoid the optical path deviation caused by assembly errors and ensure that the reflected light can accurately cover the sensitive area of the photocell 52 (such as reducing edge light leakage).

[0062] Moreover, the smooth treatment of the chamfered edge (such as a 45° chamfer) can reduce the sharp edge diffraction of light and reduce the probability of stray light entering the photocell.

[0063] In addition, the symmetry of the square hole in the horizontal and vertical directions is more likely to match the geometric shape of the color reaction area and restrict stray light in non-target directions (such as scattered light from the edge of the test strip).

[0064] Optionally, the main body of the light-transmitting hole 11 adopts a circular design, which can limit the stray light from passing through the light-transmitting hole 11 and finally entering the detection hole, and improve the color reaction efficiency of the blood and the red light in the detection hole.

[0065] The areas of the light-transmitting sheet 2 corresponding to the light-transmitting hole 11 and the receiving hole 12 in the detection base 1 are all light-transmitting areas, and the other areas are non-light-transmitting areas. For example, the non-light-transmitting area can be sprayed with light-shielding paint.

[0066] The area of the light-transmitting sheet 2 corresponding to the light-transmitting hole 11 in the detection base 1 is all light-transmitting, which can ensure that the red light emitted by the lamp bead 51 passing through the light-transmitting hole 11 can pass through the light-transmitting sheet 2 and the reflection hole 41 and reach the corresponding detection hole in the test strip 61 above, and react with the blood in the detection hole to produce a color reaction.

[0067] The area of the light-transmitting sheet 2 corresponding to the receiving hole 12 in the detection base 1 is all light-transmitting. Since the receiving hole 12 and the reflection hole 41 are in one-to-one correspondence, the area of the light-transmitting sheet 2 corresponding to the reflection hole 41 in the detection middle frame 4, that is, the area corresponding to the receiving hole, is also an all-light-transmitting area. Thus, the reflected light reflected from the upper detection hole by the reflection hole 41 can pass through the light-transmitting sheet 2 to reach the lower receiving hole 12 and reach the photoelectric cell 52 below through the receiving hole 12.

[0068] A detection circuit board 5 is fixedly arranged below the detection base 1. The detection circuit board 5 is used for photoelectric detection and data processing.

[0069] At least one lamp bead 51 and at least one photoelectric cell 52 are integrated on the detection circuit board 5.

[0070] At least one lamp bead 51 corresponds one-to-one with at least one light-transmitting hole 11 in the upper detection base 1, the all-light-transmitting area of the light-transmitting sheet 2, at least one reflection hole 41 in the detection middle frame 4, and each detection hole of each test strip in the reagent kit limited by the detection cover plate 3 in sequence, so as to realize that the red light irradiated by the lamp bead 51 can pass through the corresponding upper light-transmitting hole 11, the light-transmitting sheet 2, and the reflection hole 41 in sequence and reach the corresponding detection hole of the test strip in the reagent kit.

[0071] At least one photoelectric cell 52 corresponds one-to-one with at least one receiving hole 12 in the upper detection base 1, the all-light-transmitting area of the light-transmitting sheet 2, at least one reflection hole 41 in the detection middle frame 4, and each detection hole of each test strip in the reagent kit limited by the detection cover plate 3 in sequence, so as to realize that the reflected light after the detection hole reacts with the red light can be reflected by the reflection hole 41 and pass through the corresponding lower light-transmitting sheet 2 and receiving hole 12 in sequence to reach the corresponding photoelectric cell 52, and then perform photoelectric conversion.

[0072] Here, the lamp bead 51 can be an LED red light lamp.

[0073] Please refer to the followingFigure 5 , Figure 5 shows the process 100 of a blood lipid detection method using a multi-channel blood lipid detection device as described in Figure 1 and each of the above optional embodiments. The blood lipid detection method includes the following steps: Figure 1 shows the process 100 of a blood lipid detection method using a multi-channel blood lipid detection device as described in Figure 1 and each of the above optional embodiments. The blood lipid detection method includes the following steps:

[0074] Step 101, prepare the reagent kit.

[0075] At least one test strip can be placed in the reagent kit, and each test strip can be provided with at least one detection hole.

[0076] Step 102, use the detection cover plate 3 to limit and fix the reagent kit.

[0077] Specifically, the reagent kit needs to be placed at the corresponding position of the detection cover plate 3 manually or by an automatic device to achieve the limit and fixation of the reagent kit by the detection cover plate 3.

[0078] Step 103, drop blood into the detection holes of the test strips in the reagent kit.

[0079] Here, blood can be dropped into some or all of the test strips in the already limited and fixed reagent kit manually or by an automatic sampling device. The blood dropped into the detection holes will undergo corresponding chemical reactions for the detection items. Here, specifically how to drop the blood is designed according to actual needs. For example, blood samples from the same organism or from different organisms can be dropped according to actual scenario needs.

[0080] When dropping blood into the test strip, blood can be independently dropped into each detection hole. Or at least two detection holes can be grouped together. By dropping blood into one of the detection holes, for example, three detection holes are grouped together and blood is dropped into the middle detection hole. After the blood is dropped into the middle detection hole, it can diffuse to the other two detection holes on each test strip, and then the blood in each detection hole will undergo corresponding chemical reactions.

[0081] Step 104, the lamp beads 51 on the detection circuit board 5 emit red light.

[0082] The substances generated after the corresponding chemical reactions of the blood in each detection hole after dropping blood have absorption spectra near the red light wavelength, which causes the chemical reflection coefficient in the detection hole film to change. Therefore, by controlling the lamp beads 51 on the detection circuit board 5 to emit red light, the red light emitted by the lamp beads 51 will sequentially pass through the light-transmitting holes 11 corresponding to the lamp beads 51 in the detection base 1, the light-transmitting area in the light-transmitting sheet 2, and the reflection holes 41 in the detection middle frame 4 and finally irradiate the corresponding detection holes of the test strip.

[0083] Subsequently, the blood in the detection hole on the test strip will react with the red light to produce a color reaction and emit reflected light. The reflected light spectrum emitted by the detection hole is reflected by the corresponding reflection hole 41 in the detection middle frame 4 below the test strip and then passes through the full-transmission area of the light-transmitting sheet 2 and the receiving hole 12 in the detection base 1 in sequence, and finally is received by the corresponding photovoltaic cell 52 on the detection circuit board 5.

[0084] Step 105, after the photovoltaic cell 52 receives the reflected light spectrum, it converts the optical signal into an electrical signal, thereby measuring the intensity of the reflected light.

[0085] If the measured intensity of the reflected light is smaller, it indicates that the concentration of the substance being tested is higher; conversely, the greater the intensity of the reflected light, the lower the concentration of the substance being tested.

[0086] Subsequently, the concentration value can be calculated based on the corresponding relationship between the intensity of the reflected light and the concentration of the substance being tested. That is, the concentration values of different blood lipid detection items can be calculated.

[0087] It should be noted that, in order to ensure the photoelectric conversion effect, the distance between the detection circuit board 5 and the reagent kit placed in the detection cover 3 is the detection distance. That is, the distance of the light from the lamp bead 51 to the detection hole on the test strip. In practice, the thickness of the light-transmitting sheet 2 can be designed according to the above detection distance.

[0088] It should be noted that the implementation details and technical effects of each step in the sample detection method provided by the embodiments of the present disclosure can refer to the descriptions of other embodiments in the present disclosure, and will not be elaborated herein.
