[0002] In modern medicine, it is a very common technical means to infer the physiological condition of the source of biological samples by measuring the content of specific biochemical substances in biological samples, such as blood and urine. Among them, the more mainstream method is to measure by optical means, that is, to irradiate the above biological samples with light of a specific wavelength so that the specific biochemical substances in the above biological samples react with the above light, which may be absorption of the above light, so that the light intensity of the above light is weakened; or after absorbing the above light, another specific wavelength of light is stimulated (photoelectric colorimetry principle). By monitoring the changes in the light passing through the above biological samples, the content of the specific biochemical substances in the above biological samples can be determined.

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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 work are within the scope of protection of the present invention.

[0035] The core of the present invention is to provide a biochemical immunoassay analyzer, a schematic diagram of a specific embodiment of which is shown in FIG. Figure 1 As shown, it is called the specific implementation mode 1, which includes a light source component 100, a light splitting component 200 and a plurality of colorimetric components 300;

[0036] The light source assembly 100 is used to provide the output light, and the output light is monochromatic light;

[0037] The light splitting component 200 is used to split the output light into multiple identical outgoing light beams, and each of the outgoing light beams is respectively emitted into the corresponding colorimetric component 300;

[0038] The colorimetric component 300 is used to receive the emitted light and collect the optical signal after the emitted light passes through the biological sample;

[0039] The output end of the light splitting component 200 corresponds to the colorimetric component 300 one by one.

[0040] The light splitting component 200 may be a light splitting optical fiber; the light splitting optical fiber has a certain degree of softness and toughness, which can make the optical path arrangement inside the biochemical immunoassay analyzer more free.

[0041] It is important to note that Figure 1 The portion framed by the dotted line indicates that all structures within the frame are the colorimetric component 300 , rather than all structures within the frame being collectively referred to as the colorimetric component 300 .

[0042] A structural schematic diagram of a specific embodiment of the biochemical immunoassay analyzer provided by the present invention is shown in FIG. Figure 2 As shown in the figure, the colorimetric component 300 is fixedly connected to the same positioning substrate 400; the biochemical immunoassay analyzer has very high requirements for the stability of the optical path, and any slight change in the amount of light or angle of the light incident on the colorimetric component 300 will affect the final measurement result. Therefore, the positioning substrate 400 is used to fix the colorimetric device, so that the colorimetric device will not be displaced due to external force, which can improve the stability and service life of the device.

[0043] The structural schematic diagram of a specific implementation of the colorimetric component 300 is as follows Figure 7 As shown, the installation process is: first install the refractor 330 into the refractor mounting block 320, and then tighten it with the plastic set screw 310, install the optical path shaper 340 and the sealing ring 350 into the light source refraction box 360, and then tighten it with the refractor mounting block 320, and install the signal acquisition PD370 located on the signal amplifier board 380 on the opposite side.

[0044] Figure 8It is a schematic structural diagram of the light source refraction box 360 from another angle, wherein the optical fiber connector 361 is used to connect the splitting optical fiber.

[0045] Fig. 9 It is a schematic structural diagram of the refractor mounting block 320 from another angle.

[0046] Furthermore, the colorimetric component 300 further includes a shielding cover 390; the shielding cover 390 is used to shield external electromagnetic signal interference, so that the detection result obtained by the colorimetric device is more accurate.

[0047] The biochemical immunoassay analyzer provided by the present invention includes a light source component 100, a spectroscopic component 200 and a plurality of colorimetric components 300; the light source component 100 is used to provide the output light, and the output light is monochromatic light; the spectroscopic component 200 is used to divide the output light into a plurality of identical outgoing lights, and each of the outgoing lights is respectively emitted into the corresponding colorimetric component 300; the colorimetric component 300 is used to receive the outgoing light and collect the optical signal after the outgoing light passes through the biological sample; the output end of the spectroscopic component 200 corresponds to the colorimetric component 300 one by one. The present invention divides the light emitted by the same light source component 100 into a plurality of beams through the spectroscopic component 200 and emits them into different colorimetric components 300, so that the biochemical immunoassay analyzer in the present invention can analyze biological samples in a plurality of colorimetric components 300 at the same time, which greatly improves the working efficiency of the biochemical immunoassay analyzer compared with the biochemical immunoassay analyzer in the prior art that can only analyze one biological sample at the same time.

[0048] On the basis of the first specific implementation, the above-mentioned light splitting component 200 is further improved to obtain the second specific implementation. The structural schematic diagram of the improved light splitting component 200 is as follows: Figure 3 As shown, it includes a light source component 100, a light splitting component 200 and a plurality of colorimetric components 300;

[0049] The light source assembly 100 is used to provide the output light, and the output light is monochromatic light;

[0050] The light splitting component 200 is used to split the output light into multiple identical outgoing light beams, and each of the outgoing light beams is respectively emitted into the corresponding colorimetric component 300;

[0051] The colorimetric component 300 is used to receive the emitted light and collect the optical signal after the emitted light passes through the biological sample;

[0052] The output end of the light splitting component 200 corresponds to the colorimetric component 300 one by one;

[0053] The light splitting optical fiber is a Y-type optical fiber.

[0054] Compared with the above-mentioned specific implementation, the difference of the present application is that the present specific implementation defines the above-mentioned light splitting component 200, and the remaining structures are the same as the above-mentioned specific implementation, which will not be elaborated here.

[0055] This specific implementation method defines the light splitting component 200 as a Y-type optical fiber, that is, there are two colorimetric devices corresponding to the two light output ports of the Y-type optical fiber respectively. To split a beam of light into multiple beams of light with almost the same properties, the more beams there are, the higher the process difficulty and the lower the stability. Therefore, this specific implementation method adopts a Y-type optical fiber that splits the output light into two, which not only improves the working efficiency of the biochemical immunoassay analyzer, but also improves the working stability of the biochemical immunoassay analyzer.

[0056] On the basis of the second specific implementation, the above light source assembly 100 is further improved to obtain a third specific implementation, the structural diagram of which is as follows: Figure 3 As shown, it includes a light source component 100, a light splitting component 200 and a plurality of colorimetric components 300;

[0057] The light source assembly 100 is used to provide the output light, and the output light is monochromatic light;

[0058] The light splitting component 200 is used to split the output light into multiple identical outgoing light beams, and each of the outgoing light beams is respectively emitted into the corresponding colorimetric component 300;

[0059] The colorimetric component 300 is used to receive the emitted light and collect the optical signal after the emitted light passes through the biological sample;

[0060] The output end of the light splitting component 200 corresponds to the colorimetric component 300 one by one;

[0061] The light splitting optical fiber is a Y-type optical fiber;

[0062] The light source assembly 100 includes a light emitting module 110 and a light filtering module 120;

[0063] The light emitting module 110 is used to emit multi-color light;

[0064] The filter module 120 is used to filter the polychromatic light to obtain the output light;

[0065] The filter module 120 is a filter wheel 123;

[0066] The filter wheel 123 includes a plurality of filters 1233 corresponding to different wavelengths. The filter wheels 1233 are rotated to align the light outlets of the light emitting modules 110 .

[0067] The difference between this specific embodiment and the above specific embodiment is that this specific embodiment further defines the composition and structure of the light source assembly 100, and the remaining structures are the same as those of the above specific embodiment, which will not be elaborated here.

[0068] Figure 4 Schematic diagram of the exploded structure of the connection between the light emitting module 110 and the filter module 120 in this specific embodiment, Figure 5 1 is a schematic diagram of the structure of the light source assembly 100, wherein the filter wheel 123 has a hole at the center, is equipped with a rotating shaft 124 of the filter wheel 123, a bearing 125 and a synchronous pulley 126, and is connected to a sliding optical fiber connection seat 115. The optical shaping device 112 and the fan 114 are also mounted on the sliding optical fiber connection seat 115 and pressed by a halogen lamp fixing frame 111. The halogen lamp 113 is installed into the sliding optical fiber connection seat 115 from the side. The stepper motor 121 is mounted on the bottom of the sliding optical fiber connection seat 115 and is connected to the filter wheel 123 by a synchronous belt 122. The positioning light 116 provides precise positioning for the filter wheel 123.

[0069] The structure explosion diagram of the filter wheel 123 is as follows Figure 6 As shown, it includes a filter wheel 1231, a wheel sealing ring 1232, a filter mirror 1233 and a filter wheel cover 1234.

[0070] In particular, the driving motor of the filter wheel 123 is a stepper motor 121; when the stepper motor 121 is not overloaded, the motor speed and stop position only depend on the frequency and pulse number of the pulse signal, and are not affected by load changes. Therefore, the position of the filter 1233 on the filter wheel 123 can be positioned more accurately, thereby improving working stability.

[0071] Furthermore, the light source assembly 100 also includes a positioning light 116 to further ensure the precise positioning of the filter 1233 .

[0072] It should be noted that the light emitting device of the light source assembly 100 is a halogen lamp 113 .

[0073] This specific implementation further defines the structure of the light source assembly 100 , and filters the polychromatic light emitted by the light emitting module 110 through the filter wheel 123 , thereby achieving rapid switching of the output light of different wavelengths, and further improving the working efficiency of the biochemical immunoassay analyzer.

The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
