[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0024] Blood glucose or urine glucose detectors are widely used medical instruments. In the prior art, according to different detection methods, blood glucose or urine glucose detectors can be mainly divided into two categories: electrochemical method and optoelectronic method. The electrochemical method is one of the most commonly used blood glucose or urine glucose detection methods at present. It indirectly reflects the concentration of sugar in blood glucose or urine glucose by measuring the change in current; the optoelectronic method measures the concentration of sugar in blood glucose or urine glucose through optical means. The optoelectronic method usually uses the change in the color or light transmittance of the test strip as the detection basis. However, during the detection process, the above two detection methods are limited by the detection principle and are more likely to be affected by external conditions, resulting in large detection errors and poor detection repeatability.

[0025] Based on this, an exemplary embodiment of the present application provides a sugar detector, which includes an optical component, a sample sheet to be detected, and a detector. The optical component is configured to emit incident light; the sample sheet to be detected is disposed above the optical component, and the sample to be detected is coated on the sample sheet to be detected; the detector is disposed above the sample sheet to be detected. Thus, the incident light emitted by the optical component irradiates the sample sheet to be detected in a direction perpendicular to the sample sheet to be detected. After transmission, it can be emitted to the detector in a direction forming an angle with the incident light. For sample sheets with different sugar concentrations, the angle between the transmitted light and the incident light is different. Therefore, the position where the emitted light irradiates the detector is different. According to the different positions of the emitted light received by the detector, the angle between the transmitted light and the incident light can be calculated, and thus the sugar concentration of the sample to be detected can be determined. There is no physical contact between the sample sheet to be detected and the optical component and the detector of this sugar detector, avoiding the problems of poor contact and large detection errors caused by using electrodes, probes, etc. for contact reaction detection of sugar concentration in conventional detection methods. At the same time, by using the angle of deflection of the light after transmission as a parameter for the sugar concentration of the sample sheet to be detected, multiple repeated detections can be performed, and the results of multiple repeated detections are not easily affected by external conditions, and the consistency of the repeated detection accuracy is good.

[0026] An exemplary embodiment of the present application provides a sugar detector, as Figure 1 and 2 shown, the sugar detector includes an optical component 200, a sample sheet 300 to be detected, and a detector 400. Among them, the optical component 200 is configured to emit incident light. Preferably, the incident light is a laser beam, and the incident laser beam irradiates the sample sheet 300 to be detected in a direction perpendicular to the sample sheet 300 to be detected; the sample sheet 300 to be detected is disposed above the optical component 200, and the sample to be detected is coated on the sample sheet 300 to be detected; the detector 400 is disposed above the sample sheet 300 to be detected, and the detector 400 can detect different positions of different lights irradiated thereon. As Figure 3 shown, the incident light emitted by the optical component 200 irradiates the sample sheet 300 to be detected. After transmission, it is emitted to the detector 400 in a direction forming an angle with the incident light. Exemplarily, the angle between the emitted light and the incident light is denoted as α.

[0027] In the patent with the application number CN200910243118.6 and the title of "Molecularly Imprinted Photonic Crystal for Glucose Detection", a molecularly imprinted photonic crystal for glucose detection and its preparation method are disclosed. This photonic crystal has specific adsorption properties for glucose. In one embodiment, the sample slice to be detected is configured as a molecularly imprinted photonic crystal for glucose detection. This photonic crystal can react to sugars. Under normal circumstances, it can adsorb the sugars in the sample to be detected and swell. After that, its volume increases, resulting in a change in the angle of the refracted light. Thus, when the sugar concentration changes, the refractive index on the surface of the photonic crystal also changes. Therefore, the angle α between the emitted light and the incident light also changes, and the position where the emitted light irradiates on the detector 400 changes. In this way, according to the different positions of the emitted light received by the detector 400, the angle between the emitted light and the incident light after transmission can be calculated, and thus the sugar concentration of the sample to be detected can be determined. In the sugar detector of this application, the photonic crystal used only reacts to sugars and has no reaction to other components. Therefore, when detecting the sample to be detected, it will not be affected by other components, and the detection accuracy is high.

[0028] There is no need for physical contact between the sample slice 300 to be detected and the optical component 200 and the detector 400 of this sugar detector, which avoids the problems of poor contact and large detection errors caused by using electrodes, probes, etc. for contact reaction detection of sugar concentration in conventional detection methods. The sugar concentration is judged by detecting the angle between the incident light and the emitted light. Therefore, it has the characteristics of high detection sensitivity and fast reaction. At the same time, by using the angle of deflection of the light after transmission as the parameter of the sugar concentration of the sample slice 300 to be detected, multiple repeated detections can be carried out. Moreover, the results of multiple repeated detections are not easily affected by external conditions, and the consistency of the repeated detection accuracy is good.

[0029] As Figure 1 and 2 shown, this sugar detector further includes a housing 100. The housing 100 includes a main housing 101, an upper housing 102 and a lower housing 103. The upper housing 102 and the lower housing 103 are spaced apart and arranged on the main housing 101. A display panel 500 and an operation button 600 are embedded on the housing 100. A controller 900, a detector 400 and an optical component 200 are arranged inside the housing 100. The display panel 500, the operation button 600, the detector 400 and the optical component 200 are all electrically connected to the controller 900. In this way, the controller 900 can process the received information and calculate the sugar concentration of the sample to be detected according to the measured information. When it is necessary to detect the sugar concentration of the sample slice 300 to be detected, place the sample slice 300 to be detected well and press the operation button 600 to detect the sample slice 300 to be detected.

[0030] For convenient real-time detection, the sugar detector further includes a battery 800 disposed inside the housing 100. The battery 800 is electrically connected to the display panel 500, the operation button 600, the detector 400, the optical component 200, and the controller 900. A charging interface is further provided at the bottom of the housing 100, and the charging interface is electrically connected to the battery 800 to supply power to and charge each component, so as to realize portable measurement of sugar concentration anytime and anywhere.

[0031] As Figure 2 shown, a card slot feeding mechanism 700 is provided between the upper housing 102 and the lower housing 103. The card slot feeding mechanism 700 is provided with a card slot for carrying the sample sheet, and a through hole for the incident light to pass through is provided at the bottom of the card slot. Exemplarily, the card slot feeding mechanism 700 is configured to be slidably connected to the housing 100 through a guide rail and a pressing and rebounding mechanism. The pressing and rebounding mechanism can use a conventional structure in the existing design. Thus, when an external force is applied to the card slot feeding mechanism 700, the card slot feeding mechanism 700 pops out of the housing 100. Then, the sample sheet 300 to be detected is placed in the card slot, and then the card slot feeding mechanism 700 is pushed into the housing 100. The operation button 600 is activated, and the optical component 200 emits incident light. The incident light irradiates the sample sheet 300 to be detected. After transmission, it irradiates the detector 400 at an angle α with the incident light. The detector 400 calculates the angle between the light emitted after transmission and the incident light based on the obtained light position, and then calculates the sugar concentration of the sample to be detected. The sugar concentration is displayed through the display panel 500, so that the sugar concentration can be quickly detected.
