[0026] Figure 1 FIG. 1 is a schematic diagram showing a hemoglobin concentration measurement method and system provided by an embodiment of the present invention, and a concentration measurement device applicable to an intelligent device. Figure 1As shown, the hemoglobin concentration measurement system includes a counting plate 100 and a measuring component 200, wherein the counting plate 100 is provided with a plurality of cavities 101, and two adjacent cavities are separated by a transparent partition 102, wherein one of the cavities 101 contains a hemoglobin sample to be detected, which is recorded as a hemoglobin solution cavity, wherein the other cavity 101 is empty, which is recorded as an air cavity, the partition 102 between the hemoglobin cavity and the air cavity is a second partition, and the partition 102 on the other side of the hemoglobin cavity is recorded as a first partition; the counting plate 100 and the measuring component 200 can be relatively moved, from It is convenient to measure the transmittance of each cavity position on the counting board 100 respectively; the measuring component 200 includes an emitter 210 and a photoelectric conversion module 220, and the emitter 210 and the photoelectric conversion module 220 are respectively arranged on both sides of the counting board 100, for testing the transmittance of different positions of the counting board 100; in this embodiment, the emitter 210 refers to a light emitting diode, and the photoelectric conversion module 220 includes a photodiode, an amplifying circuit and an analog-to-digital converter, etc., for receiving a light signal and sending the light intensity value of the light signal to a control unit, which is a known technology and need not be elaborated here.

[0027] Specifically, the emitter 210 is fixedly arranged in front of the counting plate 100, the photoelectric conversion module 220 is fixedly arranged behind the counting plate 100, and a movable slide rail 300 is arranged under the counting plate 100. The counting plate 100 moves along the direction of the movable slide rail 300, thereby facilitating the measuring component 200 to measure the transmittance of different positions of the counting plate 100.

[0028] Alternatively, a first guide rail parallel to the counting board 100 is provided in front of the counting board 100, a second guide rail parallel to the counting board 100 is provided behind the counting board 100, a first transfer seat is provided on the first guide rail, the emitter 210 is provided on the first transfer seat, a second transfer seat is provided on the second guide rail, and the photoelectric conversion module 220 is provided on the second transfer seat. The first transfer seat and the second transfer seat are driven by an external driving device and move synchronously along the first guide rail and the second guide rail respectively, thereby achieving the purpose of measuring the transmittance of each cavity on the counting board 100.

[0029] In this embodiment, the emitter 210 emits an initial light, which is received by the photoelectric conversion module 220 after passing through the counting plate. The photoelectric conversion module 220 receives the light and sends the light intensity value to the control unit. Before testing the hemoglobin sample to be tested contained in the cavity of the counting plate 100, a hemoglobin solution corresponding to at least one known hemoglobin concentration value is measured; under the condition that the light intensity of the light emitted by the emitter 210 remains unchanged, the relationship between the hemoglobin concentration and the light intensity value of the light received by the photoelectric conversion module 220 is obtained.

[0030] Specifically, measuring the concentration of hemoglobin solution (HGB) is actually measuring the degree of light absorption of the hemoglobin solution, that is, the absorption coefficient. Under the condition of a certain light intensity of the light-emitting diode, the higher the HGB concentration value, the greater the absorption coefficient, and the smaller the light intensity value received by the photoelectric conversion module.

[0031] Set the known hemoglobin solution concentration to When , the light intensity of the light received by the photoelectric conversion module 220 after the initial light emitted by the emitter 210 passes through the air cavity of the counting plate is I, and the light intensity of the light received by the photoelectric conversion module 220 after the initial light emitted by the emitter 210 passes through the known hemoglobin solution cavity of the counting plate is I0, wherein, multiple light intensity values ​​of the incident light can be obtained by measuring the light emitted by the emitter through the air cavity of the counting plate by multiple or multi-point methods, and finally the light intensity I of the light received by the photoelectric conversion module 220 is obtained based on the multiple light intensity values ​​of the incident light; multiple or multi-point methods can be used to measure the light emitted by the emitter through the known hemoglobin solution cavity of the counting plate to obtain multiple light intensity values, and finally the light intensity I0 of the light received by the photoelectric conversion module 220 is obtained based on the multiple light intensity values ​​of the incident light, the multi-point method refers to the same initial light passing through different positions of the counting plate cavity, and the multiple method refers to the same initial light passing through the same position of the counting plate cavity multiple times.

[0032] According to the "Lambert-Beer Law" formula: , where A is the absorbance and T is the transmittance (transmittance), which is characterized by the light intensity I of the photoelectric conversion module after the initial light emitted by the emitter passes through the air cavity of the counting plate and the light intensity I of the photoelectric conversion module after the initial light emitted by the emitter passes through the hemoglobin solution cavity to be tested in the counting plate x The ratio of T = I / I x , b is the thickness of the absorption layer, is the concentration of the absorbing substance, K is the molar absorption coefficient, which is related to the properties of the absorbing substance and the wavelength λ of the incident light. The properties of the absorbing substance in hemoglobin solutions with different concentrations are the same. Therefore, in the present invention, the absorbing substance refers to hemoglobin, K is a fixed value, and the size of the counting plate cavity is fixed, and b is a fixed value. In this embodiment, when the hemoglobin concentration is known to be , T=I / I0.

[0033] Since K and b are fixed values, the formula can be Consider A A linear function, due to , so we know .

[0034] The hemoglobin concentration of the hemoglobin solution to be tested is The light intensity of the light received by the photoelectric conversion module after the initial light emitted by the emitter 210 passes through the air chamber of the counting plate is I, and the light intensity of the light received by the photoelectric conversion module 220 after the initial light emitted by the emitter 210 passes through the hemoglobin solution chamber to be tested of the counting plate is I x When, based on the formula , and T=I / I x The hemoglobin concentration of the hemoglobin solution to be tested is obtained as .

[0035] Figure 2 is a flow chart of a first hemoglobin concentration measurement method provided by an embodiment of the present invention, such as Figure 2 As shown, the hemoglobin concentration measurement method includes steps S110 to S140, which are specifically as follows:

[0036] Step S110: Perform a transmittance test on the counting plate with the hemoglobin sample placed thereon to obtain a test data point set. , based on the experimental data point set, a curve graph corresponding to the displacement-light intensity relationship is established, such as Figure 3 As shown; where i∈[1, n], in the initial state, the emitter and the photoelectric conversion module are both located on the outer side of the counting board.

[0037] The method of step S110 is specifically performed as follows:

[0038] The external driving device drives the counting board to move different displacements along the direction of the moving slide rail, and the light signal emitted by the transmitter is received by the photoelectric conversion module, so as to obtain the light intensity received by the photoelectric conversion module corresponding to the different displacements of the counting board; as the counting board moves, the light signal emitted by the transmitter will be directly received by the photoelectric conversion module through the air, and then through the cavity of the counting board and then received by the photoelectric conversion module, so that the photoelectric conversion module obtains the light intensity corresponding to the movement of the counting board to different positions;

[0039] Obtain the displacement-light intensity curves corresponding to the movement of the counting plate to multiple position stages in the curve graph corresponding to the displacement-light intensity relationship, and the displacement-light intensity curves corresponding to the multiple position stages are combined into a curve graph corresponding to the displacement-light intensity relationship, such as Figure 4 As shown; wherein, the multiple position stages include an air position stage, a first partition position stage, an air cavity position stage, a second partition position stage, and a hemoglobin cavity position stage. The air position stage refers to the presence of only air medium between the emitter and the photoelectric conversion module, and the measuring component and the counting board are in a staggered setting state.

[0043] In the curve diagram corresponding to the displacement-light intensity relationship, obtain the test data point corresponding to the peak corresponding to the maximum light intensity value, which is recorded as the first test data point; the peak with the maximum light intensity value is the peak value of the displacement-light intensity curve corresponding to the second partition position stage;

[0044] In the curve graph corresponding to the displacement-light intensity relationship, the test data point corresponding to the second trough close to the first test data point is obtained, which is recorded as the second test data point. The second test data point is one of the test data points in the air chamber position stage; the test data points corresponding to the troughs in the curve graph corresponding to the displacement-light intensity relationship are traversed, and the x-axis coordinate value x of the test data point corresponding to each trough in the curve graph corresponding to the displacement-light intensity relationship is obtained. 01 、x 02 …x 0(m-1) 、x 0m and the x-axis coordinate value x of the test data point corresponding to the peak with the largest intensity value t , where m is the number of valleys in the curve corresponding to the displacement-light intensity relationship, then x 0(m-1) is the x-axis coordinate value of the test data point corresponding to the second trough close to the peak with the maximum light intensity value in the curve graph corresponding to the displacement-light intensity relationship, recorded as x k , then x k =x 0(m-1) ;

[0045] The first k test data points and the last k test data points close to the second test data point in the curve graph corresponding to the displacement-light intensity relationship are obtained, that is, other test data points corresponding to the air chamber position stage in the displacement-light intensity curve, so as to obtain the test data point set corresponding to the counting plate moving to the air chamber position stage. The test data point set corresponding to the air chamber position stage includes the first test data point, the first k test data points and the last k test data points close to the second test data point in the curve graph corresponding to the displacement-light intensity relationship; wherein the maximum value of k can be ⌊ ⌋, where d refers to the displacement of the counting plate when the measuring component collects adjacent test data points, L refers to the preset length of the air chamber stage on the counting plate, in this embodiment, k is 5, and the coordinates corresponding to the first k test data points and the last k test data points close to the second test data point and the second test data point are (x0, y0), (x1, y1)…(x k-1 ,y k-1 ), (x k ,y k ), (x k+1 ,y k+1 ), (x k+2 ,y k+2 )…(x 2k ,y 2k ).

[0046] For example, by measuring the length of the air cavity of the counting plate, it can be known that the length of the air cavity position is 4mm=4000μm, and the displacement of the counting plate during two adjacent acquisitions of the measuring component is 125μm. The corresponding test data points in the air cavity position stage are approximately 4000÷125=32. When the first test data point is obtained, up to 15 test data points before and after the first test data point can be collected as the test data point set corresponding to the air cavity position stage as needed.

[0047] Step S130, obtaining a set of experimental data points corresponding to the stage when the counting plate moves to the hemoglobin chamber position in the curve graph corresponding to the displacement-light intensity relationship.

[0048] Specifically, the method of step S130 includes the following steps:

[0049] Obtain the light intensity values ​​of the test data points corresponding to multiple peaks and multiple troughs in the curve graph corresponding to the displacement-light intensity relationship; specifically, use the scipy.signal.find_peaks() method in Python to obtain the peaks and troughs in the curve graph corresponding to the displacement-light intensity relationship, and then obtain the light intensity value of the test data point corresponding to each peak and the light intensity value of the test data point corresponding to each trough;

[0050] In the curve diagram corresponding to the displacement-light intensity relationship, obtain the test data point corresponding to the peak corresponding to the maximum light intensity value, which is recorded as the first test data point; the peak with the maximum light intensity value is the peak value of the displacement-light intensity curve corresponding to the second partition position stage;

[0051] In the curve graph corresponding to the displacement-light intensity relationship, obtain a point whose x-axis coordinate value is greater than the x-axis coordinate value x of the first test data point. tThe corresponding y-axis coordinate values ​​of the multiple test data points are recorded as y1, y2…y n-1 ,y n , the y-axis coordinate value of the first test data point is y t ;

[0052] Based on y n -y n-1 ≤△T to obtain the test data point set corresponding to the stage when the counting plate moves to the hemoglobin holding cavity position, wherein △T is a preset threshold value; in the curve diagram corresponding to the displacement-light intensity relationship, the test data point whose x-axis coordinate value is greater than the x-axis coordinate value of the first test data point is used as a reference, recorded as the third test data point set, the third test data point set is traversed, and the test data point set corresponding to the hemoglobin holding cavity position stage is obtained from the third test data point set, recorded as the fourth test data point set, and the test data points in the fourth test data point set meet the requirement that the y-axis coordinate value of the current test data point minus the y-axis coordinate value of the previous test data point is less than the preset threshold value △T.

[0053] Step S140: Obtain the light intensity mean value of the air cavity stage based on the experimental data point set corresponding to the air cavity position stage obtained in step S120. , based on the experimental data point set corresponding to the hemoglobin cavity position stage obtained in step S130, the light intensity mean value of the hemoglobin cavity position stage is obtained. In this embodiment, , .

Refers to the light intensity of the light received by the photoelectric conversion module after the initial light emitted by the transmitter passes through the air cavity of the counting plate.

[0055] Specifically, according to the "Lambert-Beer Law" formula: , where A is absorbance and T is transmittance (transmittance). When the hemoglobin concentration of the hemoglobin solution to be measured is , T represents the light intensity of the light received by the photoelectric conversion module after the initial light emitted by the emitter passes through the air cavity of the counting plate. The light intensity of the light received by the photoelectric conversion module after the initial light emitted by the transmitter passes through the hemoglobin solution chamber to be tested in the counting plate The ratio of , b is the thickness of the absorption layer, is the concentration of the absorbing substance, K is the molar absorption coefficient, which is related to the properties of the absorbing substance and the wavelength λ of the incident light. The properties of the absorbing substance in hemoglobin solutions with different concentrations are the same. Therefore, in the present invention, the absorbing substance refers to hemoglobin, K is a fixed value, and the size of the counting plate cavity remains unchanged, and b is a fixed value. Since k and b are fixed values, the formula can be Consider A A linear function, due to , so we know , and finally through the formula The hemoglobin concentration of the hemoglobin solution to be tested can be calculated .
