Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved by the present application more clear, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

It should be noted that, in this application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" means two or more, and the meaning of "at least one" means one or more, unless specifically defined otherwise.

Next, an application scenario of the jaundice tester calibration device provided in the embodiments of the present application will be described.

Jaundice testers may also be referred to as percutaneous jaundice testers, for measuring bilirubin concentration values in the human body. Currently, there are two types of common jaundice testers, namely, a jaundice tester adopting a blue-green double-color light source, and a jaundice tester adopting a natural light source. When bilirubin concentration is measured by the jaundice tester, the probe of the jaundice tester is tightly attached to the skin of a human body. Then, for the jaundice tester adopting the blue-green dual-color light source, the blue light source and the green light source in the probe of the jaundice tester emit blue light and green light sequentially, and after the blue light and the green light pass through skin tissues of a human body, part of the blue light and the green light are absorbed, and the rest part of the blue light and the green light are reflected. Wherein, bilirubin in human body has a large absorbance of blue light, and hemoglobin absorbs blue light, and hemoglobin has substantially the same absorbance of blue light and green light. Based on the above, the probe of the jaundice tester can receive the blue light and the green light reflected by the skin tissue of the human body, and based on the light intensity of the reflected green light, the influence on the light intensity of the reflected blue light caused by the absorption of the blue light by the hemoglobin is removed, so that the bilirubin concentration value in the human body is calculated.

Unlike a jaundice tester using a blue-green light source, for a jaundice tester using a natural light source, the natural light source within the probe of the jaundice tester emits natural light. After natural light passes through skin tissue of human body, the blue light component and the green light component in the natural light can be absorbed and reflected as well, so that the probe of the jaundice tester can receive the reflected light, and based on the principle, the bilirubin concentration value in the human body can be calculated by the light intensity of the blue light component and the green light component in the reflected light.

The jaundice tester calibrating device that this application embodiment provided can be used for calibrating above-mentioned two kinds of jaundice testers to improve the measurement accuracy of jaundice tester.

Next, description will be given of a jaundice tester calibration device provided in an embodiment of the present application.

Fig. 1 is a schematic structural diagram of a calibration device 01 for a jaundice tester according to an embodiment of the present application. As shown in fig. 1, the jaundice tester calibration apparatus 01 includes a light beam processing module 10, an electrical signal processing module 11, and a light emitting module 12. The light beam processing module 10 is configured to obtain a first incident light and a second incident light based on an output light beam of the jaundice tester, and convert the first incident light into a first electrical signal and the second incident light into a second electrical signal; the electric signal processing module 11 is used for determining the light intensity of the first reflected light and the light intensity of the second reflected light based on a preset bilirubin concentration value, the first electric signal and the second electric signal; the light emitting module 12 is configured to output a reflected light beam to the jaundice tester based on the light intensity of the first reflected light and the light intensity of the second reflected light, so that the jaundice tester is calibrated based on the reflected light beam.

In the embodiment of the present application, the input end of the beam processing module 10 is aligned with the light source of the jaundice tester, or the input end of the beam processing module 10 is closely attached to the light source of the jaundice tester. Thus, when calibration is started, the jaundice tester to be calibrated is started, and the light source of the jaundice tester emits a light beam towards the input end of the light beam processing module 10. The beam processing module 10 receives an output beam of the jaundice tester, obtains a first incident light and a second incident light based on the output beam of the jaundice tester, and then converts the first incident light into a first electrical signal and converts the second incident light into a second electrical signal.

As illustrated in fig. 2, the beam processing module 10 may include a beam splitter 101, a first filter 102, a second filter 103, a first photoelectric conversion unit 104, and a second photoelectric conversion unit 105.

The beam splitter 101 faces the outgoing direction of the output beam of the jaundice tester, the first optical filter 102 is located on the reflection light path of the beam splitter 101, and the second optical filter 103 is located on the transmission light path of the beam splitter 101. The first photoelectric conversion unit 104 may be located in the exit direction of the first optical filter 102, and the second photoelectric conversion unit 105 may be located in the exit direction of the second optical filter 103.

In a first possible case, when the output beam of the jaundice tester is natural light, the beam splitter 101 is configured to split the output beam into a first incident light and a second incident light; the first optical filter 102 is used for passing light in a blue light band in the first incident light, blocking light outside the blue light band, and the second optical filter 103 is used for passing light in a green light band in the second incident light, blocking light outside the green light band; the first photoelectric conversion unit 104 is configured to convert first incident light passing through a first filter into a first electrical signal, and the second photoelectric conversion unit 105 is configured to convert second incident light passing through a second filter into a second electrical signal.

It should be noted that, when the jaundice tester adopts a natural light source, the output beam of the jaundice tester is a natural light beam, that is, a white light beam containing light components of different wavebands. In this case, after the output light beam is incident on the beam splitter 101, a part of the output light beam is reflected by the beam splitter 101 and reaches the first filter 102, where the part of the output light beam is the first incident light; another part of the output light beam passes through the beam splitter 101 and then reaches the second filter 103, and the part of the output light beam is the second incident light.

The beam splitter 101 may be a polarizing beam splitter prism, in which case the first incident light is S polarized light, and the second incident light is P polarized light. Of course, the beam splitter 101 may be another beam splitter that is independent of the polarization direction and is used to split one beam into two beams, which is not limited in the embodiment of the present application.

Since the first incident light and the second incident light both include light with different wavelengths, it is known based on the working principle of the jaundice tester described above that the jaundice tester mainly calculates bilirubin concentration values based on the light intensities of blue light and green light reflected after passing through human skin tissue. Based on this, in order to simulate blue light and green light reflected by human skin tissue later, in the embodiment of the present application, a first filter and a second filter may be further provided in the beam processing module 10. When the first incident light enters the first filter 102, the first filter 102 may pass light of a blue light band of the first incident light and block light of a wavelength band other than the blue light band, so as to filter light of a wavelength band other than the blue light of the first incident light. Similarly, when the second incident light enters the second filter 103, the second filter 103 may pass light of a green light band of the second incident light and block light of a band other than the green light, so as to filter out light of the second incident light of a band other than the green light.

The first filter 102 and the second filter 103 may be narrowband filters. In addition, the wavelength range of the blue light band through which the first filter 102 can pass may be 430nm to 480nm, and the wavelength range of the green light band through which the second filter can pass may be 520nm to 560nm. Of course, the wavelength range of the blue light band that the first filter 102 can pass may be appropriately adjusted with respect to the 460nm as the center wavelength, and the wavelength range of the green light band that the second filter 103 can pass may be appropriately adjusted with respect to the 550nm as the center wavelength, which is not limited in this embodiment.

Since the first photoelectric conversion unit 104 is located in the emission direction of the first filter 102, the second photoelectric conversion unit 105 is located in the emission direction of the second filter 103. Accordingly, the first incident light passing through the first filter 102 will be incident to the first photoelectric conversion unit 104, and the first photoelectric conversion unit 104 can convert the first incident light into a first electrical signal. Similarly, the second incident light passing through the second filter is incident on the second photoelectric conversion unit 105, and the second photoelectric conversion unit 105 can convert the second incident light into a second electric signal.

Wherein the first photoelectric conversion unit 104 and the second photoelectric conversion unit 105 are each a device for converting an optical signal into an electrical signal. The first photoelectric conversion unit 104 and the second photoelectric conversion unit 105 may be photodetectors, for example, photomultiplier tubes, but may be other types of photodetectors. In addition, the converted first electrical signal and second electrical signal may be analog signals.

In a second possible case, when the output beam of the jaundice tester includes blue light and green light, the beam splitter 101 is configured to reflect the blue light to obtain a first incident light, and transmit the green light to obtain a second incident light, where the blue light and the green light are output by the jaundice tester in a time-sharing manner.

It should be noted that, when the jaundice tester adopts the blue-green dual-color light source, the output light beam of the jaundice tester includes blue light and green light, and the blue light and the green light are alternately emitted in a time-sharing manner. For example, the jaundice tester may control the blue light source to continuously output blue light, and then control the green light source to continuously output green light, and then control the blue light source to continuously output blue light, until the output times of the blue light source and the output times of the green light source reach preset times.

Based on this, when the jaundice tester outputs blue light, the blue light is incident to the spectroscope 101, the spectroscope 101 reflects the incident blue light to the first optical filter 102, and at this time, the blue light reflected to the first optical filter 102 is the first incident light. Since the first filter 102 may pass light of the blue wavelength band, the first incident light may be incident to the first photoelectric conversion unit 104 through the first filter 102, so that the first incident light is converted into a first electrical signal by the first photoelectric conversion unit 104.

When the jaundice tester outputs green light, the green light enters the beam splitter 101 and then passes through the beam splitter 101 to reach the second optical filter 103, and at this time, the green light transmitted from the beam splitter 101 is the second incident light. Since the second filter 103 may pass light of the green wavelength band, the second incident light may be incident to the second photoelectric conversion unit 105 through the second filter 103, so that the second incident light is converted into a second electrical signal by the second photoelectric conversion unit 105.

It should be noted that, the blue light output by the jaundice tester may also be mixed with light of other wavelength bands during the process of reaching the first optical filter 102, so when the first incident light passes through the first optical filter 102, the first optical filter 102 may filter out light of other wavelength bands except the blue light band mixed in the first incident light, and similarly, the second optical filter 103 may also filter out light of other wavelength bands except the green light band mixed in the second incident light. In this way, the influence of light components of other wavebands on the calibration process can be avoided.

Optionally, referring to fig. 3, the beam processing module 10 further includes a first attenuation sheet 106 and a second attenuation sheet 107, where the first attenuation sheet 106 is located between the beam splitter 101 and the first photoelectric conversion unit 104, and the second attenuation sheet 107 is located between the beam splitter 101 and the second photoelectric conversion unit 105; the first attenuation sheet 106 is used for adjusting the light intensity of the first incident light, and the second attenuation sheet 107 is used for adjusting the light intensity of the second incident light.

It should be noted that, the first photoelectric conversion unit 104 and the second photoelectric conversion unit 105 may have a maximum light intensity supported, and the light intensities of the first incident light and the second incident light output by the beam splitter 101 may exceed the maximum light intensity. Based on this, in order to avoid that the light intensities of the incident lights respectively incident on the two photoelectric conversion units exceed the maximum light intensities supported by them as much as possible, the light intensity of the first incident light may be reduced by the first attenuation sheet 106, and the light intensity of the second incident light may be reduced by the second attenuation sheet 107.

In one possible implementation, a first attenuation sheet 106 may be located between the beam splitter 101 and the first optical filter 102, and a second attenuation sheet 107 is located between the beam splitter 101 and the second optical filter 103. Thus, the first incident light reflected by the beam splitter 101 passes through the first attenuation sheet 106 to reduce the light intensity, and then passes through the first filter 102 to filter out light in other wavelength bands than the blue light band. Similarly, the second incident light transmitted from the beam splitter 101 passes through the second attenuation sheet 107 to reduce the light intensity, and then passes through the second filter 103 to filter out light in other wavelength bands than the green light wavelength band.

In another possible implementation, the first attenuation sheet 106 may be located between the first optical filter 102 and the first photoelectric conversion unit 104, and the second attenuation sheet 107 may be located between the second optical filter 103 and the second photoelectric conversion unit 105. In this case, the first incident light passing through the first filter 102 reduces the light intensity through the first attenuation sheet 106, and then is incident on the first photoelectric conversion unit 104; the second incident light passing through the second filter 103 reduces the light intensity through the second attenuation sheet 107, and then is incident on the second photoelectric conversion unit 105.

After the beam processing module 10 converts the first incident light and the second incident light into the first electric signal and the second electric signal, the first electric signal and the second electric signal may be input to the electric signal processing module 11, and the electric signal processing module 11 may determine the light intensities of the first reflected light and the second reflected light to be simulated based on the preset bilirubin concentration value, the first electric signal, and the second electric signal.

For example, referring to fig. 4, the electrical signal processing module 11 may include a first analog-to-digital converter 111, a second analog-to-digital converter 112, and a processing unit 113. Wherein the first analog-to-digital converter 111 is used for converting the first electrical signal into a first digital signal, and the second analog-to-digital converter 112 is used for converting the second electrical signal into a second digital signal; the processing unit 113 is configured to obtain a preset output light intensity of blue light and a preset output light intensity of green light of the jaundice tester, and determine a light intensity of the first reflected light and a light intensity of the second reflected light based on the first digital signal, the second digital signal, the preset output light intensity of blue light, the preset output light intensity of green light, and the preset bilirubin concentration value.

In the embodiment of the present application, the first electrical signal and the second electrical signal output by the beam processing module 10 may be analog signals, and the signal supported by the processing unit 113 is a digital signal. Based on this. In the embodiment of the present application, the first electrical signal output by the beam processing module 10 may be converted into a first digital signal by the first analog-to-digital converter 111, and the second electrical signal output by the beam processing module 10 may be converted into a second digital signal by the second analog-to-digital converter 112. Thereafter, the first analog-to-digital converter 111 and the second analog-to-digital converter 112 may each transmit the converted first digital signal and second digital signal to the processing unit 113.

The processing unit 113 calculates the first light intensity according to the first digital signal after receiving the first digital signal, and calculates the second light intensity according to the second digital signal after receiving the second digital signal. The first light intensity is a blue light intensity measured value obtained by the calibration device 01 based on the output light beam of the jaundice tester, and the second light intensity is a green light intensity measured value obtained by the calibration device 01 based on the output light beam of the jaundice tester.

In addition, the processing unit 113 may also obtain the preset output light intensity of the blue light and the preset output light intensity of the green light of the calibrated jaundice tester. If the preset output light intensities of the first light intensity and the blue light satisfy the first condition and the preset output light intensity of the second light intensity and the green light satisfies the second condition, the processing unit 113 may acquire a blue reference reflected light intensity and a green reference reflected light intensity corresponding to the preset bilirubin concentration value, and calculate the light intensity of the first reflected light and the light intensity of the second reflected light based on the preset output light intensity of the blue light, the preset output light intensity of the green light, the first light intensity, the second light intensity, the blue reference reflected light intensity, and the green reference reflected light intensity.

For example, the calibration device 01 for a jaundice tester provided in the embodiments of the present application may further include an input/output unit, through which the processing unit 113 may receive the preset output light intensity of the blue light and the preset output light intensity of the green light of the jaundice tester input by the manufacturer of the jaundice tester. Thereafter, the processing unit 113 may compare the preset output light intensity of the blue light with the first light intensity, and if the absolute value of the difference between the preset output light intensity of the blue light and the first light intensity is not greater than the first threshold value and the first light intensity is not greater than the preset output light intensity of the blue light, it is indicated that the measured value of the blue light intensity obtained by the processing unit 113 is not greatly different from the preset output light intensity of the blue light, and in this case, it may be determined that the first light intensity and the preset output light intensity of the blue light satisfy the first condition. Similarly, the processing unit 113 may compare the preset output light intensity of the green light with the second light intensity, and determine that the preset output light intensity of the green light and the second light intensity satisfy the second condition if the absolute value of the difference between the preset output light intensity of the green light and the second light intensity is not greater than the second threshold value and the second light intensity is not greater than the preset output light intensity of the green light. The first threshold value and the second threshold value may be equal or unequal.

Optionally, if the absolute value of the difference between the preset output light intensity of the blue light and the first light intensity is greater than the third threshold value or the first light intensity is greater than the preset output light intensity of the blue light, it is indicated that the first light intensity and the preset output light intensity of the blue light have a larger difference, and at this time, it may be determined that the preset output light intensity of the first light intensity and the preset output light intensity of the blue light do not satisfy the first condition. If the absolute value of the difference between the preset output light intensity of the green light and the preset output light intensity of the second light intensity is larger than the fourth threshold value or the second light intensity is larger than the preset output light intensity of the green light, the fact that the difference between the second light intensity and the preset output light intensity of the green light is larger is indicated, and at the moment, it can be determined that the preset output light intensity of the second light intensity and the preset output light intensity of the green light do not meet the second condition. Wherein the third threshold is not smaller than the first threshold, the fourth threshold is not smaller than the second threshold, and the third threshold and the fourth threshold may be equal or not equal.

After determining that the preset output light intensities of the first light intensity and the blue light satisfy the first condition and the preset output light intensities of the second light intensity and the green light satisfy the second condition, the processing unit 113 may receive the preset bilirubin concentration value and the blue light reference reflected light intensity and the green light reference reflected light intensity corresponding to the preset bilirubin concentration value through the input output unit. Then, calculating to obtain the estimated reflected light intensity of the blue light based on the ratio of the preset output light intensity of the blue light to the first light intensity and the blue light reference reflected light intensity corresponding to the preset bilirubin concentration value; and calculating the estimated reflected light intensity of the green light based on the ratio of the preset output light intensity of the green light to the second light intensity and the reference reflected light intensity of the green light corresponding to the preset bilirubin concentration value. And then, determining the light intensity of the first reflected light and the light intensity of the second reflected light based on the ratio of the blue light reference reflected light intensity to the green light reference reflected light intensity corresponding to the preset bilirubin concentration value and the predicted reflected light intensity of the blue light and the predicted reflected light intensity of the green light, wherein the ratio of the light intensity of the first reflected light to the light intensity of the second reflected light is equal to the ratio of the blue light reference reflected light intensity to the green light reference reflected light intensity.

For example, assuming that the preset output intensity of blue light is 1000, the preset output intensity of green light is 800, the first intensity is 950, the second intensity is 750, the preset bilirubin concentration value is 10mg/dL, the blue light reference reflected intensity corresponding to the preset bilirubin concentration value is 500, the green light reference reflected light intensity is 400, the processing unit 113 may determine that the estimated reflected light intensity of blue light=500/(1000/950) =475, green predicted reflected light intensity=400/750/375. And then taking the predicted reflected light intensity of the blue light as the light intensity of the first reflected light, and calculating the light intensity of the second reflected light according to the ratio of the reference reflected light intensity of the blue light to the reference reflected light intensity of the green light and the light intensity of the first reflected light, wherein the light intensity of the second reflected light is=475 (500/400) =380. Alternatively, the estimated reflected light intensity of the green light may be used as the light intensity of the second reflected light, and the light intensity of the first reflected light may be calculated according to the ratio of the reference reflected light intensity of the blue light to the reference reflected light intensity of the green light and the light intensity of the second reflected light, where the light intensity=500++400×375=468.75.

Optionally, if the preset output light intensities of the first light intensity and the blue light do not meet the first condition, and/or the preset output light intensities of the second light intensity and the green light do not meet the second condition, the processing unit 113 may output an alarm prompt through the input/output unit to prompt that the jaundice tester is failed or fails.

Optionally, in some possible cases, the jaundice tester calibration device 01 provided in the embodiments of the present application may further include a storage unit, where reference parameters of the jaundice tester manufactured by the different manufacturers may be stored in advance. The reference parameters comprise preset output light intensity of blue light, preset output light intensity of green light and a mapping relation between bilirubin concentration values and reference reflected light intensity of a jaundice tester manufactured by corresponding manufacturers, wherein the mapping relation comprises blue light reference reflected light intensity and green light reference reflected light intensity corresponding to different bilirubin concentration values. Based on this, the processing unit 113 may receive, through the input/output unit, identification information of a manufacturer of the jaundice tester to be calibrated, obtain, according to the identification information, a preset output light intensity of blue light and a preset output light intensity of green light of the jaundice tester manufactured by the manufacturer, and determine, through the method described above, whether the first light intensity and the preset output light intensity of blue light satisfy the first condition, and whether the second light intensity and the preset output light intensity of green light satisfy the second condition. If both the first condition and the second condition are satisfied, the processing unit 113 may receive a preset bilirubin concentration value through the input-output unit. And then, based on the identification information of the manufacturer of the jaundice tester, acquiring a mapping relation included by the reference parameters of the manufacturer, and acquiring blue light reference reflected light intensity and green light reference reflected light intensity corresponding to a preset bilirubin concentration value from the mapping relation. Thereafter, the processing unit 113 may calculate the light intensity of the first reflected light and the light intensity of the second reflected light with reference to the above-described method.

Optionally, referring to fig. 5, in the embodiment of the present application, the electrical signal processing module 11 may further include a first filter 114 and a second filter 115, where an output end of the first filter 114 is connected to an input end of the first analog-to-digital converter 111, and an output end of the second filter 115 is connected to an input end of the second analog-to-digital converter 112; the first filter 114 is used for filtering noise signals in the first electrical signal, and the second filter 115 is used for filtering noise signals in the second electrical signal.

It should be noted that, a noise signal may be mixed in the electrical signal obtained by the optical conversion unit, and the noise signal may affect the accuracy of the light intensity of the first reflected light and the light intensity of the second reflected light that are determined later. Based on this, in the embodiment of the present application, a first filter 114 may also be connected between the first photoelectric conversion unit 104 and the first analog-to-digital converter 111. In this way, the first photoelectric conversion unit 104 may output the first electric signal to the first filter 114 after converting the first incident light into the first electric signal. The first filter 114 may filter the first electrical signal to remove noise signals in the first electrical signal, and then the first filter 114 may output the filtered first electrical signal to the first analog-to-digital converter 111. Similarly, a second filter 115 may be further connected between the second photoelectric conversion unit 105 and the second analog-to-digital converter 112, so as to filter noise signals in the second electrical signal.

Optionally, referring to fig. 5, the electrical signal processing module 11 may further include a first operational amplifier 116 and a second operational amplifier 117, wherein an output end of the first operational amplifier 116 is connected to an input end of the first filter 114, and an output end of the second operational amplifier 117 is connected to an input end of the second filter 115; the first operational amplifier 116 is used to amplify the first electrical signal and the second operational amplifier 117 is used to amplify the second electrical signal.

It should be noted that, the power of the electrical signal converted by the photoelectric conversion unit may be relatively small, so that the difficulty in determining the light intensity of the reflected light by using the digital signal obtained by converting the electrical signal later will be relatively large. Based on this, in the embodiment of the present application, the first operational amplifier 116 may be further connected between the first photoelectric conversion unit 104 and the first filter 114, so that the first photoelectric conversion unit 104 may output the converted first electrical signal to the first operational amplifier 116, and the first operational amplifier 116 amplifies the first electrical signal by a preset multiple. The amplified first electrical signal is then output to the first filter 114. Since the first operational amplifier 116 amplifies the first electrical signal, the noise signal in the first electrical signal is also amplified, and filtering the amplified first electrical signal by the first filter 114 can better remove the noise signal in the first electrical signal. Similarly, a second operational amplifier 117 may be further connected between the second photoelectric conversion unit 105 and the second filter 115, and the second electrical signal may be amplified by a predetermined multiple by the second operational amplifier 117, and then filtered by the second filter 115.

After determining, by the electrical signal processing module 11, the light intensity of the first reflected light and the light intensity of the second reflected light corresponding to the preset bilirubin concentration value, the electrical signal processing module 11 may control the light emitting module 12 to output the reflected light beam to the jaundice tester based on the light intensity of the first reflected light and the light intensity of the second reflected light.

For example, referring to fig. 6, the light emitting module 12 may include a first driving unit 121, a second driving unit 122, a first light emitting unit 123, and a second light emitting unit 124; wherein the first driving unit 121 is configured to drive the first light emitting unit 123 to output the first reflected light based on the light intensity of the first reflected light; the second driving unit 122 is configured to drive the second light emitting unit 124 to output the second reflected light based on the light intensity of the second reflected light. The first reflected light is blue light, and the second reflected light is green light.

It should be noted that, the first driving unit 121 and the second driving unit 122 may be connected to the processing unit 113 in the electrical signal processing module 11. In this way, the processing unit 113 may transmit the light intensity of the first reflected light to the first driving unit 121 and transmit the light intensity of the second reflected light to the second driving unit 122 after determining the light intensity of the first reflected light and the light intensity of the second reflected light.

The first driving unit 121 may drive the first light emitting unit 123 to emit blue light of a corresponding light intensity after receiving the light intensity of the first reflected light. At this time, the blue light is the first reflected light simulated by the calibration device 01. Similarly, the second driving unit 122 may drive the second light emitting unit 124 to emit green light of a corresponding intensity after receiving the intensity of the second reflected light. At this time, the green light is the second reflected light simulated by the calibration device 01. The first light emitting unit may be a blue LED (light-emitting diode) lamp, and the second light emitting unit may be a green LED lamp.

If the output light beam of the aforementioned jaundice tester to be calibrated includes blue light and green light, that is, the jaundice tester adopts a blue-green bi-color light source, the first driving unit 121 and the second driving unit 122 may time-divisionally drive the corresponding light emitting units to output reflected light. If the output light beam of the jaundice tester to be calibrated is natural light, that is, the jaundice tester adopts a natural light source, the first driving unit 121 and the second driving unit 122 may simultaneously drive the corresponding light emitting units to output reflected light.

It should be noted that, in one possible implementation manner of this embodiment of the present application, the light emitting directions of the first light emitting unit 123 and the second light emitting unit 124 are both towards the probe of the jaundice tester, so that the first reflected light emitted by the first light emitting unit 123 and the second reflected light emitted by the second light emitting unit 124 may directly enter the probe of the jaundice tester, and the jaundice tester may determine the bilirubin concentration measurement value based on the received light intensity measurement value of the first reflected light and the light intensity measurement value of the second reflected light.

Optionally, in another possible implementation of the embodiments of the present application, referring to fig. 7, the light emitting module 12 may further include a combiner 125. In this case, when the output beam of the jaundice tester is natural light, the beam combiner 125 is configured to combine the first reflected light and the second reflected light into a reflected beam, and output the reflected beam to the jaundice tester. When the output beam of the jaundice measuring instrument includes blue light and green light, the beam combiner 125 is configured to transmit the first reflected light and the second reflected light to the jaundice measuring instrument, respectively.

Specifically, the beam combiner 125 may be located in the light emitting directions of the first and second light emitting units 123 and 124, and the light emitting direction of the beam combiner 125 is toward the probe of the jaundice tester.

If the output beam of the jaundice tester is natural light, that is, the jaundice tester adopts a natural light source, it can be known from the foregoing description that the first driving unit 121 and the second driving unit 122 will simultaneously drive the corresponding light emitting units to emit reflected light. Based on this, the first reflected light emitted from the first light emitting unit 123 and the second reflected light emitted from the second light emitting unit 124 may be incident together on the beam combiner 125, and the beam combiner 125 combines the incident first reflected light and second reflected light into a reflected light beam and outputs the reflected light beam to the probe of the jaundice tester. After receiving the reflected light beam, the jaundice tester can measure the intensity of blue light and the intensity of green light in the reflected light beam to determine bilirubin concentration measurements.

If the output beam of the jaundice tester includes blue light and green light, that is, the jaundice tester adopts a blue-green dual-color light source, it can be seen from the foregoing description that the first driving unit 121 and the second driving unit 122 will time-divisionally drive the corresponding light emitting units to emit reflected light. Based on this, when the first light emitting unit 123 emits light, the first reflected light emitted by the first light emitting unit 123 enters the probe of the jaundice tester after passing through the beam combiner 125. When the second light emitting unit 124 emits light, the second emitted light emitted by the second light emitting unit 124 is incident to the probe of the jaundice tester after passing through the beam combiner 125. At this time, the first reflected light and the second reflected light incident to the jaundice tester at different times are reflected light beams output to the jaundice tester by the calibration device 01. Accordingly, the jaundice meter may determine the bilirubin concentration measurement based on the received light intensity measurement of the first reflected light and the light intensity measurement of the second reflected light.

After determining the bilirubin concentration measurement, the jaundice tester may compare the bilirubin concentration measurement with the previously described preset bilirubin concentration value. If the bilirubin concentration measurement is equal to a preset bilirubin concentration value, it may be determined that the jaundice tester does not need to be calibrated. If the bilirubin concentration measurement is not equal to the preset bilirubin concentration value, the jaundice test meter may be calibrated based on a difference between the bilirubin concentration measurement and the preset bilirubin concentration value.
