It should be understood that the following drawings only show certain embodiments of the present application and therefore should not be regarded as limiting the scope.

[0048] Figure 2 It is a flow chart of a jaundice detection method disclosed in an embodiment of the present application. DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0050] Embodiment 1

[0051] See also Figure 1 , Figure 1 Schematic diagram of a transcutaneous jaundice detector disclosed in the embodiment of the present application. Figure 1 As shown, the transcutaneous jaundice detector of the embodiment of the present application includes an optical module and a hardware circuit module, wherein the optical module is electrically connected to the hardware circuit module, the optical module is used to emit incident light that enters the skin, and the optical module is also used to receive reflected light after being absorbed by bilirubin and filter the reflected light to obtain blue light and green light.

[0052] Further, the hardware circuit module is used to collect the ADC value of blue light and the ADC value of green light, and calculate the jaundice value based on the ADC value of blue light and the ADC value of green light;

[0053] The hardware circuit module is also used to adjust the intensity of the incident light based on the ADC value of the blue light and a preset threshold.

[0054] The embodiment of the present application can emit incident light that hits the skin through the optical module, and can receive the reflected light after bilirubin absorption and filter the reflected light to obtain blue light and green light, and then the blue light and green light can be processed through the hardware circuit module to calculate the jaundice value, thereby realizing jaundice detection. At the same time, through the hardware circuit module, the intensity of the incident light can be adjusted based on the ADC value of the blue light and the preset threshold, and then the intensity of the incident light of the transcutaneous jaundice detector can be adjusted according to the severity of the jaundice condition, thereby avoiding the LED light source from working at high intensity all the time, increasing its service life, and avoiding the harm of high-intensity blue light to the baby. When the LED light source has light decay, on the other hand, the LED current can be increased in time to compensate, thereby improving the accuracy of jaundice detection.

[0055] In the embodiment of the present application, as an example, it is assumed that there are two jaundice patients, namely patient A and patient B, wherein the severity of jaundice of patient A is greater than that of patient B. In this scenario, for the prior art, its detection instrument will emit incident light of fixed intensity and irradiate it on the patient's skin, wherein, since the instrument of the prior art cannot adjust the intensity of the incident light, the same intensity of incident light is used for patient A and patient B. Furthermore, if the doctor first uses incident light of lower intensity to detect patient B, and then irradiates patient A with incident light of the same intensity, it may appear that the incident light of this intensity can diagnose the jaundice of patient B, but for patient A, the incident light of this intensity is not enough, that is, the energy of the incident light is insufficient, and the jaundice value of patient A cannot be accurately measured.

[0056] In comparison, since the embodiment of the present application can adjust the intensity of the incident light based on the ADC value of the blue light and the preset threshold, when switching from detecting patient B to detecting patient A, the intensity of the incident light can be adjusted, and the energy of the incident light can be made large enough to detect jaundice in patient A, thereby improving the accuracy of jaundice detection. At the same time, when switching from detecting patient A to detecting patient B, it is possible to avoid irradiating patient B with incident light of excessive intensity.

The method according to claim 7, characterized in that The calculation formula corresponding to the increased LED output current calculated based on the ADC value of the blue light and the preset threshold is: I = K2*In*(Bb); Among them, I is the increased LED output current, B is the preset threshold value; In is the current LED output current, b is the ADC value of the blue light, and K2 is the proportional coefficient.

10. The method according to claim 6, characterized in that The method further comprises: When the increased LED output current is greater than the preset upper limit value, it is determined whether the ADC value of the blue light is less than the preset threshold value. If the ADC value of the blue light is less than the preset threshold value, an out-of-measurement range display signal is generated and sent to the display module.
