[0054] The following will describe in detail some embodiments of the present application in conjunction with the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0055] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a framework of an immunochromatographic analyzer provided by an embodiment of the present application.

[0056] As Figure 1 shown, the immunochromatographic analyzer 100 includes a sampling device 10, an optical detection device 20, and a signal analysis device 30. Among them, the sampling device 10 is provided with at least one placement position for placing a target object to be measured, and the target object to be measured includes, but is not limited to, a test strip card or a reagent card containing a sample to be measured. The optical detection device 20 is configured to detect the target object and output a corresponding signal. The signal analysis device 30 is configured to analyze the signal output by the optical detection device 20 to obtain a detection result of the target object.

[0057] In some embodiments, the optical detection device 20 includes a first light source assembly 21, a second light source assembly 22, a light source driving component 23, a signal receiving component 24, and a signal processing component 25. The first light source assembly 21 is configured to emit a first optical signal to the target object. The second light source assembly 22 is configured to emit a second optical signal to the target object, and the wavelengths of the first optical signal and the second optical signal are different. Optionally, the first optical signal is a visible light signal, and the second optical signal is a laser signal. Optionally, the visible light signal is green light with a wavelength of 577 nm to 492 nm. For example, the wavelength of the first optical signal is 530 nm ± 20 nm. Optionally, the second optical signal is ultraviolet light with a wavelength of 400 nm to 315 nm. For example, the wavelength of the second optical signal is 365 nm ± 20 nm.

[0058] In some embodiments, the light source driving component 23 is configured to connect the first light source assembly 21 and the second light source assembly 22 in a time-sharing manner, and drive the first light source assembly 21 to emit the first optical signal and drive the second light source assembly 22 to emit the second optical signal in a time-sharing manner. That is, the light source driving component 23 can drive the first light source assembly 21 to emit the first optical signal at a first time, and can drive the second light source assembly 22 to emit the second optical signal at a second time, and the first time and the second time are different.

[0059] The signal receiving component 24 is configured to receive the reflected optical signal of the first optical signal reflected by the target object and receive the excited optical signal generated by the second optical signal exciting the target object.

[0060] The signal processing component 25 is configured to process the signal output by the signal receiving component 24 and output the processed signal to the signal analysis device 30.

[0061] Exemplarily, when a reagent card containing a sample to be tested needs to be detected by the colloidal gold method, the immunochromatographic analyzer 100 controls the light source driving component 23 to drive the first light source assembly 21 to emit a first light signal to the detection position on the reagent card, and receives, through the signal receiving component 24, the reflected light signal reflected by the marker of the sample to be tested on the reagent card, and outputs a corresponding received signal. After receiving the received signal output by the signal receiving component 24, the signal processing component 25 processes the received signal and outputs it to the signal analysis device 30, so that the signal analysis device 30 can generate the detection result of the sample to be tested carried on the reagent card according to the received signal.

[0062] When a reagent card containing a sample to be tested needs to be detected by the fluorescence method, the immunochromatographic analyzer 100 controls the light source driving component 23 to drive the second light source assembly 22 to emit a second light signal to the detection position on the reagent card, and receives, through the signal receiving component 24, the excitation light signal generated by the marker of the sample to be tested on the reagent card being excited by the second light signal, and outputs a corresponding received signal. After receiving the received signal output by the signal receiving component 24, the signal processing component 25 processes the received signal and outputs it to the signal analysis device 30, so that the signal analysis device 30 can generate the detection result of the sample to be tested carried on the reagent card according to the received signal.

[0063] It can be understood that the immunochromatographic analyzer 100 is further provided with a control device 40, and the control device 40 is communicatively connected to at least one of the optical detection device 20 and the signal analysis device 30 to control the optical detection device 20 to perform optical detection on the target object, and / or control the signal analysis device 30 to analyze the signal output by the optical detection device 20, so as to obtain the detection result corresponding to the target object. Among them, the control device 40 can be one or more, and can be independently provided, or can integrate at least one of the optical detection device 20 and the signal analysis device 30, which is not limited herein.

[0064] In this embodiment, the first light source assembly 21 and the second light source assembly 22 of the optical detection device 20 share the light source driving component 23 for time-division driving, so that there is no need to separately provide a corresponding light source driving component for each light source assembly, and thus the production cost of the immunochromatographic analyzer can be effectively reduced, and the volume of the immunochromatographic analyzer can be reduced, which is convenient for the immunochromatographic analyzer to be miniaturized.

[0065] Such as Figure 1As shown, in some embodiments, the light source driving component 23 includes a driving assembly 231 and a first switch 232. Among them, the first switch 232 is connected to the driving assembly 231 and has a switchable first connection mode and second connection mode. In the first connection mode, the first switch 232 connects the driving assembly 231 and the first light source assembly 21, so that the driving assembly 231 can drive the first light source assembly 21 to emit a first optical signal. In the second connection mode, the first switch 232 connects the driving assembly 231 and the second light source assembly 22, so that the driving assembly 231 can drive the second light source assembly 22 to emit a second optical signal.

[0066] It can be understood that the switching of the connection mode of the first switch 232 can be realized by the control device 40 outputting a corresponding control signal. For example, when the control device 40 outputs a first switch control signal to the first switch 232, the first switch 232 connects the first light source assembly 21 and the driving assembly 231. When the control device 40 outputs a second switch control signal to the first switch 232, the first switch 232 connects the second light source assembly 21 and the driving assembly 231.

[0067] By the first switch 232 connecting the first light source assembly 21 and the driving assembly 231 or connecting the second light source assembly 22 and the driving assembly 231 in a time-sharing manner, so that when it is necessary for the first light source assembly 21 to emit a first optical signal, the first switch 232 can connect the driving assembly 231 and the first light source assembly 21. When it is necessary for the second light source assembly 22 to emit a second optical signal, the first switch 232 can connect the driving assembly 231 and the second light source assembly 22.

[0068] It can be understood that the first switch 232 can be a mechanical switch, a relay, or an analog switch or a switching tube, as long as it can realize time-sharing connection of the driving assembly and the corresponding light source assembly.

[0069] As Figure 1 shown, in some embodiments, the first light source assembly 21 and the second light source assembly 22 are driven by the same light source driving component 23.

[0070] Please refer to Figure 1 , in some embodiments, the reflected optical signal and the excitation optical signal are received by the same signal receiving component 24. Among them, after the signal receiving component 24 receives the reflected optical signal, it outputs a first received signal. After the signal receiving component 24 receives the excitation optical signal, it outputs a second received signal; and, the first received signal and the second received signal output by the signal receiving component 24 are processed by the same signal processing component 25 and the processed signal is output to the signal analysis device 30.

[0071] Please refer to Figure 2, in some embodiments, the signal receiving component 24 includes a first receiving component 241 and a second receiving component 242. The first receiving component 241 is configured to receive the reflected light signal and output a first received signal, and the second receiving component 242 is configured to receive the excitation light signal and output a second received signal.

[0072] The signal processing component 25 includes a first processing component 251 and a second processing component 252. The first processing component 251 is connected to the first receiving component 241, and is configured to process the first received signal output by the first receiving component 241, and output the processed first received signal to the signal analysis device 30; the second processing component 252 is connected to the second receiving component 242, and is configured to process the second received signal output by the second receiving component 242, and output the processed second received signal to the signal analysis device 30.

[0073] In this embodiment, the optical detection device 20 of the immunochromatographic analyzer 100 employs two different receiving components and processing components for the reflected light signal of the first optical signal and the excitation light signal of the second optical signal.

[0074] Please refer to Figure 3 , in some embodiments, the signal receiving component 24 includes a first receiving component 241 and a second receiving component 242.

[0075] In this embodiment, the optical detection device 20 connects to the corresponding receiving components in a time-sharing manner through a signal processing component 25, so that the signals received by the two receiving components can be processed by sharing one signal processing component.

[0076] As Figure 3 shown, exemplarily, the signal processing component 25 includes a processing component 253 and a second switch 254. Among them, the second switch 254 is connected to the processing component 253 and has a switchable third connection mode and fourth connection mode. In the third connection mode, the second switch 254 connects the processing component 253 and the first receiving component 241, so that the processing component 253 processes the signal output by the first receiving component 241 and outputs the processed signal to the signal analysis device 30; in the fourth connection mode, the second switch 254 connects the processing component 253 and the second receiving component 242, so that the processing component 253 processes the signal output by the second receiving component 242 and outputs the processed signal to the signal analysis device 30.

[0077] It can be understood that the second switch 254 can be a mechanical switch, a relay, an analog switch or a switching tube, as long as it can achieve time-division connection of the processing component and the corresponding receiving component.

[0078] It can be understood that the switching of the connection mode of the second switch 254 can be achieved by the control device 40 outputting a corresponding control signal. For example, when the control device 40 outputs a third switch control signal to the second switch 254, the second switch 254 connects the processing component 253 and the first receiving component. When the control device 40 outputs a fourth switch control signal to the second switch 254, the second switch 254 connects the processing component 253 and the second receiving component.
