[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. Various characteristic features shown in the following embodiments can be combined with each other.

[0010] Incidentally, a program for realizing the software appearing in one embodiment may be provided as a non-transitory computer-readable recording medium, or may be provided so as to be downloadable from an external server, or may be provided so that the program is launched on an external computer and its functions are realized on a client terminal (so-called cloud computing).

[0011] In addition, in various information processing according to an embodiment, an input and an output according to the input can be realized. Here, as long as an output is obtained as a result of the input, the form of information referenced in such information processing (hereinafter referred to as reference information) is not limited. The reference information may be, for example, rule-based information such as a database, a lookup table, or a predetermined function (including a judgment formula such as a regression formula constructed by a statistical method), or may be a trained model that has previously trained the correlation between the input and the output, or may be a large-scale language model that can output a desired result by inputting a prompt.

[0012] In one embodiment, the term "unit" may include, for example, a combination of hardware resources implemented by a circuit in the broad sense and software information processing that can be specifically realized by these hardware resources. In one embodiment, various information is handled, and this information is represented by, for example, physical values ​​of signal values ​​representing voltage and current, high and low signal values ​​as a binary bit collection consisting of 0 or 1, or quantum superposition (so-called quantum bits), and communication and calculation can be performed on the circuit in the broad sense.

[0013] Furthermore, a circuit in the broad sense is a circuit realized by at least appropriately combining a circuit, circuitry, a processor, and a memory. The processor may be a general-purpose processor or a dedicated circuit. In other words, it includes an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)), etc.

[0014] <Embodiment> 1. System Configuration The system configuration according to the embodiment will be described below. Fig. 1 is a diagram showing an example of the overall configuration of a blood component measuring system 1. Fig. 1 shows an overview of each device provided in the blood component measuring system 1 and a user who uses these devices. Each overview will be explained as appropriate with reference to other figures.

[0015] The blood component measuring system 1 is an information processing system that executes information processing for measuring blood components in a human body 3. In the example of Fig. 1, the blood component measuring system 1 measures the amount of glucose, which is a blood component, i.e., the blood glucose level. The blood component measuring system 1 includes a communication line 2, a server device 10, a user terminal 20, and a measuring device 30.

[0016] The measuring device 30 is a device that radiates electromagnetic waves to a measurement site 4 of the human body 3 and measures the electromagnetic waves emitted through the inside of the measurement site 4. The measuring device 30 measures, for example, one or both of the amplitude and phase of the electromagnetic waves. Since the measured electromagnetic waves have a correlation with blood components, it is possible to measure the blood components based on the measurement results of the electromagnetic waves. Some blood component measurements impose a burden on the human body 3 by, for example, pricking a needle. In contrast, the measuring device 30 uses electromagnetic waves to perform non-invasive measurement that does not impose a burden on the human body 3. The measuring device 30 transmits measurement data indicating the measurement results of the electromagnetic waves to, for example, the user terminal 20.

[0017] The user terminal 20 is an information processing device for a user of the blood component measurement system 1, and is, for example, a personal computer or a tablet terminal. The user of the user terminal 20 is, for example, a measurement operator who performs the measurement of blood components (the subject of measurement himself or herself or a supporter who supports the measurement, etc.). The user terminal 20 transfers the measurement data transmitted from the measurement device 30 to the server device 10.

[0018] The server device 10 is an information processing device that executes information processing for measuring blood components. The server device 10 measures the blood components of the human body 3 based on, for example, electromagnetic wave measurement data transmitted from the user terminal 20. A method for measuring the blood components will be described in detail later. The server device 10 transmits the measurement results of the blood components to the user terminal 20, and the user terminal 20 displays the measurement results, allowing the user to know the amounts of the components in his or her blood.

[0019] 2. Hardware Configuration The hardware configuration according to the embodiment will be described below. 2 is a diagram showing an example of a hardware configuration of server device 10. Server device 10 includes a control unit 11, a storage unit 12, a communication unit 13, and a bus 14. Bus 14 electrically connects each unit included in server device 10.

[0020] (Control unit 11) The control unit 11 is, for example, a central processing unit (CPU) not shown. The control unit 11 realizes various functions related to the blood component measurement system 1 by reading out a predetermined program stored in the storage unit 12. In other words, information processing by software stored in the storage unit 12 is specifically realized by the control unit 11, which is an example of hardware, and can be executed as each functional unit included in the control unit 11. Note that the control unit 11 is not limited to being single, and may be implemented with multiple control units 11 for each function. Also, a combination of these may be used.

[0021] (Storage unit 12) The memory unit 12 stores various information defined by the above description. This can be implemented, for example, as a storage device such as a solid state drive (SSD) that stores various programs and the like related to the blood component measurement system 1 executed by the control unit 11, or as a memory such as a random access memory (RAM) that stores temporarily required information (arguments, arrays, etc.) related to the program calculations. The memory unit 12 stores various programs, variables, etc. related to the blood component measurement system 1 executed by the control unit 11.

[0022] (Communications Department 13) The communication unit 13 is configured to be able to transmit various electrical signals from the server device 10 to external components. The communication unit 13 is also configured to be able to receive various electrical signals from the external components to the server device 10. More preferably, the communication unit 13 has a network communication function, and may be implemented so that various information can be communicated between the server device 10 and external devices via the communication line 2.

[0023] Fig. 3 is a diagram showing an example of a hardware configuration of the user terminal 20. The user terminal 20 includes a control unit 21, a storage unit 22, a communication unit 23, an input unit 24, an output unit 25, and a bus 26. The bus 26 electrically connects the various units included in the user terminal 20. The control unit 21, the storage unit 22, and the communication unit 23 are similar hardware to the control unit 11, the storage unit 12, and the communication unit 13 shown in Fig. 2, although the specifications, models, and the like may be different.

[0024] (Input section 24) The input unit 24 has operation receiving means such as keys, buttons, a touch screen, a mouse, etc., and receives input operations by the user. The input unit 24 may also have a microphone and have a function of receiving voice input by the user.

[0025] (Output section 25) The output unit 25 has a display means such as a display and a sound emitting means such as a speaker, and displays visual information generated in a manner that is visible to the user, such as screens, images, icons, text, etc., on the display surface of the display, and outputs sound including voice.

[0026] Next, a description will be given of the hardware configuration of the measurement device 30. As described above, the path of the electromagnetic wave measured by the measurement device 30 is divided into two paths.

[0027] FIG. 4 is a diagram showing an example of the path of an electromagnetic wave. FIG. 4A shows an example in which an electromagnetic wave is incident on a measurement site 4 of a human body 3, and a reflected electromagnetic wave S11 reflected by components such as blood flowing inside the body is measured. FIG. 4B shows an example in which an electromagnetic wave is incident on a measurement site 4 of a human body 3, and a transmitted electromagnetic wave S21 that passes through the body and is emitted from the opposite side is measured. In either case, the electromagnetic wave penetrates into the human body 3 once, is transmitted and scattered, and a part of it is emitted to the outside of the human body 3. The measuring device 30 measures the electromagnetic wave thus emitted. Note that the location of the measurement site 4 on the human body 3 is arbitrary, but when measuring the transmitted electromagnetic wave S21, it is preferable that the measurement site 4 be a site with a small thickness such as an earlobe or a web of a palm.

[0028] Fig. 5 is a diagram showing an example of a hardware configuration of the measurement device 30. In the example of Fig. 5, an example of the hardware configuration for measuring the transmitted electromagnetic wave S21 is shown. The measurement device 30 includes a radiation unit 31, a first waveguide 41 and a second waveguide 42 (referred to as "waveguide 40" when there is no distinction between them), a first dielectric 51 and a second dielectric 52 (referred to as "dielectric 50" when there is no distinction between them), a measurement unit 32, and a communication unit 33.

[0029] The radiation unit 31 includes a signal generator, an amplifier, a transmission antenna, and the like, and radiates electromagnetic waves. The signal generator generates an electrical signal of a specific frequency, and the amplifier amplifies the generated electrical signal. The transmission antenna radiates the amplified electrical signal as an electromagnetic wave. The radiation unit 31 radiates, for example, electromagnetic waves in the millimeter wave band or microwave band. Millimeter waves are electromagnetic waves with a wavelength of 1 mm or more and 10 mm or less, and a frequency of 30 GHz or more and 300 GHz or less. Microwaves are electromagnetic waves with a wavelength of 1 cm or more and tens of cm or less, and a frequency of several hundred MHz or more and 30 GHz or less.

[0030] The waveguide 40 is a structure that confines and transmits electromagnetic waves. The waveguide 40 is configured to be, for example, a rectangular waveguide, a circular waveguide, a coaxial waveguide, or the like. The rectangular waveguide includes, for example, a metal tube with a rectangular cross section, and the circular waveguide includes a metal tube with a circular cross section. The coaxial waveguide includes a so-called coaxial cable. The waveguide 40 is configured to have a size and shape according to the frequency of the electromagnetic wave radiated from the radiation portion 31.

[0031] The dielectric 50 is an insulator that generates dielectric polarization, and is formed by stacking, for example, one or more paraffin sheets. The dielectric 50 is a transmission path through which electromagnetic waves are transmitted. The first dielectric 51 is in the form of a plate having a first surface 511 and a second surface 512. The second dielectric 52 is in the form of a plate having a first surface 521 and a second surface 522. The measurement of the electromagnetic waves is performed in a state where the second surface 512 of the first dielectric 51 and the second surface 522 of the second dielectric 52 are in close contact with the measurement site 4 of the human body 3, as shown in FIG. 5.

[0032] The first waveguide 41 has a first end 411 and a second end 412. The radiation section 31 is provided at a position where an electromagnetic wave can be incident from the first end 411 into the inside of the first waveguide 41. A first dielectric 51 is fixed to the second end 412 with the first surface 511 in contact with the second end 412. The electromagnetic wave incident into the inside of the first waveguide 41 is transmitted inside the first waveguide 41 in the radiation direction D1, and is incident into the first dielectric 51 from the second end 412.

[0033] The electromagnetic wave incident on the first dielectric 51 passes through the first dielectric 51, exits from the second surface 512, and enters the measurement site 4 of the human body 3. The measurement site 4 of the human body 3 is, for example, an earlobe as shown in FIG. 4. Of the electromagnetic wave incident on the measurement site 4, the electromagnetic wave that passes through the measurement site 4 reaches the second surface 522 of the second dielectric 52 as a transmitted electromagnetic wave S21 as shown in FIG. 4. The electromagnetic wave incident on the second dielectric 52 from the second surface 522 passes through the second dielectric 52, and exits from the first surface 521.

[0034] The second waveguide 42 has a first end 421 and a second end 422. The second dielectric 52 is fixed to the second end 422 with the first surface 521 in contact with it. The transmitted electromagnetic wave S21 emitted from the first surface 521 enters the inside of the second waveguide 42 from the second end 422. The electromagnetic wave entered the inside of the second waveguide 42 is transmitted inside the second waveguide 42 in the radiation direction D1 and exits from the first end 421.

[0035] The measurement unit 32 is provided at a position where it can measure the electromagnetic wave emitted from the first end 421, and measures the emitted transmitted electromagnetic wave S21. The measurement unit 32 has, for example, a VNA (vector network analyzer) that measures the amplitude or phase of the transmitted electromagnetic wave S21. The measurement unit 32 supplies measurement data indicating the measurement result to the communication unit 33. The communication unit 33 transmits the supplied measurement data to the user terminal 20 by wireless or wired communication.

[0036] Here, the dielectric 50 will be described in more detail. The dielectric 50 is disposed between two transmission paths, the waveguide 40 and the measurement site 4 of the human body 3, and functions as a transmission path for impedance matching. Impedance matching means matching the impedance so as to maximize the electromagnetic waves transmitted through the two transmission paths. Here, the impedances of the first waveguide 41, the first dielectric 51, the measurement site 4 of the human body 3, the second dielectric 52, and the second waveguide 42 are respectively defined as Z1, Z2, m , Z2, Z m , Z1. The first dielectric 51 and the second dielectric 52 have an impedance Z m is configured to be a value within the range expressed by the following formula (1).

[0037]

number

[0038] Next, the dimension (thickness) of the first dielectric 51 in the radial direction D1 is defined as L51, and the dimension (thickness) of the second dielectric 52 in the radial direction D1 is defined as L52. In addition, the wavelength of the electromagnetic wave inside the first dielectric 51 and the second dielectric 52 is defined as λ mThe wavelength of the electromagnetic wave in a vacuum is λ0, and the dielectric constants of the first dielectric 51 and the second dielectric 52 are ε m Then, the first dielectric 51 and the second dielectric 52 are configured so that the dimensions L51 and L52 are within the ranges represented by the following formula (2).

[0039]

number

[0040] In this manner, dielectric 50 is configured to have dimensions within the range of ±30% of a quarter of the wavelength of the electromagnetic wave transmitted through dielectric 50, and is configured to more easily produce so-called quarter-wavelength impedance matching than when the dimensions are outside this range.

[0041] FIG. 6 is a diagram showing another example of the hardware configuration of the measurement device 30. In the example of FIG. 6, an example of the measurement device 30 when measuring the reflected electromagnetic wave S11 is shown. The measurement device 30 shown in FIG. 6 includes a radiation unit 31, a first waveguide 41, a first dielectric 51, a measurement unit 32, and a communication unit 33. That is, the measurement device 30 shown in FIG. 6 does not include the second waveguide 42 and the second dielectric 52 shown in FIG. 5. In the example of FIG. 6, the radiation unit 31 is provided at a position where the electromagnetic wave can be incident from the first end 411 of the first waveguide 41, and the measurement unit 32 is provided at a position where the electromagnetic wave emitted from the first end 411 of the first waveguide 41 can be measured.

[0042] The first waveguide 41 transmits the electromagnetic wave emitted from the radiation unit 31 in the radiation direction D1. The transmitted electromagnetic wave is incident on the measurement site 4 of the human body 3 via the first waveguide 41 and the first dielectric 51, and is scattered by blood and the like in the body. The electromagnetic wave scattered in the direction toward the measurement unit 32 becomes a reflected electromagnetic wave S11 and is emitted from the measurement site 4 of the human body 3. The emitted reflected electromagnetic wave S11 is incident on the measurement unit 32 via the first dielectric 51 and the first waveguide 41. The measurement unit 32 measures the incident reflected electromagnetic wave S11. The communication unit 33 transmits the measurement data supplied from the measurement unit 32 to the user terminal 20 by wireless or wired communication, as in the example of FIG. 5. The impedance of the first dielectric 51 and the dimension L51 in the radiation direction D1 are the same as in the example of FIG. 5.

[0043] 3. Information Processing The information processing according to the embodiment will be described below. In the following description, the server device 10, the user terminal 20, and the measurement device 30 are described as the subjects of each information processing, but the information processing is executed by at least one processor included in the blood component measurement system 1, i.e., a processor included in the control unit of each device. The blood component measurement system 1 executes a measurement process to measure blood components in a human body 3, for example.

[0044] Fig. 7 is an activity diagram showing an example of a measurement process. The measurement process is started, for example, when the measurement device 30 shown in Fig. 5 is attached to the measurement site 4 of the human body 3. First, the measurement device 30 radiates an electromagnetic wave (activity A11). The radiated electromagnetic wave passes through the measurement site 4 of the human body 3 via the first waveguide 41 and the first dielectric 51 shown in Fig. 5, and reaches the measurement unit 32 as a transmitted electromagnetic wave S21 shown in Fig. 4 via the second dielectric 52 and the second waveguide 42. The measurement device 30 measures the transmitted electromagnetic wave S21 that has arrived (activity A12).

[0045] The measurement device 30 measures one or both of the amplitude and phase of the transmitted electromagnetic wave S21, and generates measurement data indicating the measurement results (activity A13). The measurement device 30 transmits the generated measurement data to the user terminal 20. The user terminal 20 transfers the transmitted measurement data to the server device 10 (activity A14). Upon receiving the transferred measurement data, the server device 10 acquires the measurement results indicated by the received measurement data (activity A21).

[0046] The server device 10 extracts features of the electromagnetic waves from the acquired measurement data (activity A22). The server device 10 extracts one or both of the amplitude and phase of the electromagnetic waves as features that indicate a correlation with the amount of blood components. Here, the server device 10 stores an estimator having a function of estimating blood components. The server device 10 stores, for example, an estimator that performs adaptive estimation using a complex-valued neural network. A complex-valued neural network is a neural network in which inputs, weights, outputs, etc. are expressed by complex numbers, and can efficiently process information that cannot be captured by real numbers.

[0047] The server device 10 inputs the extracted feature amount to the estimator (activity A23). Next, the server device 10 outputs component information indicating the amount of blood component estimated by the estimator (activity A24). The server device 10 outputs the component information to, for example, the user terminal 20. The user terminal 20 displays the output component information (activity A25). The component information thus displayed indicates, for example, the blood glucose level of the human body 3.

[0048] 4. Numerical Analysis Next, the components of the blood component measurement system 1 are simulated, and the results of analyzing the values ​​of the measurement results by the measurement device 30 are described. For the numerical analysis, electromagnetic field simulation software HFSS (manufactured by Ansys, Inc.) based on the finite element method is used. A tissue model showing the biological tissue of an earlobe is used, in which the measurement site 4 of the human body 3 is set to be an earlobe, and there are two 0.2 mm skin layers, three 1.0 mm fat layers, and four 0.4 mm blood layers, with a total thickness of 5.0 mm. The area of ​​the measurement site 4 on the body surface of the human body 3 is 10 mm x 10 mm. A paraffin sheet (relative dielectric constant = 2.3, dielectric loss tangent = 0.005) is used as the dielectric 50.

[0049] FIG. 8 is a diagram showing an example of the measurement result of the reflected electromagnetic wave S11. In FIG. 8, a line graph is shown in which the vertical axis indicates the amplitude (unit: dB) of the reflected electromagnetic wave S11 and the horizontal axis indicates the frequency (unit: GHz) of the electromagnetic wave. The amplitude shown in FIG. 8 is the ratio of the amplitude measured when the human body 3 is not present to the amplitude measured when the blood glucose concentration of the human body 3 is 150 g / dL. In FIG. 8, the amplitude ratios are shown when the thickness of the paraffin sheet, i.e., the dimension L51 in the radiation direction D1 of the first dielectric 51 is changed to "0.00", "0.05", "0.10", "0.15", "0.20", "0.25", "0.30", "0.35", "0.40", "0.45", "0.50", "0.55", "0.60", "0.65", and "0.70".

[0050] When the dimension L51 is 0.00 to 0.40, the amplitude ratio changes linearly and gently from 60 to 90 GHz. This result indicates that a simple single reflection occurs on the surface of the human body 3. However, compared to these cases, when the dimension L51 is 0.45 to 0.70 mm, the amplitude ratio changes significantly from 60 to 90 GHz. This indicates that the electromagnetic wave penetrates the measurement site 4 of the human body 3, causing backscattering, and also causing partial losses to provide information on blood components.

[0051] Fig. 9 is a diagram showing another example of the measurement result of the reflected electromagnetic wave S11. Fig. 9 shows a line graph in which the vertical axis indicates the phase (unit: deg) of the reflected electromagnetic wave S11 and the horizontal axis indicates the frequency (unit: GHz) of the electromagnetic wave. The phase shift is the shift between the phase measured when the human body 3 is not present and the phase measured when the blood glucose concentration of the human body 3 is 150 g / dL. Fig. 9 shows each phase shift in the thickness of the paraffin sheet similar to Fig. 8, i.e., the dimension L51 in the radiation direction D1 of the first dielectric 51.

[0052] When the dimension L51 is 0.00 to 0.40, the phase shift changes linearly from 60 to 90 GHz. This result indicates that a simple single reflection occurs on the surface of the human body 3. However, compared to these cases, when the dimension L51 is 0.45 to 0.70 mm, the phase shift changes significantly nonlinearly from 60 to 90 GHz. This result, like the case of the amplitude ratio, indicates that the electromagnetic wave penetrates the measurement site 4 of the human body 3, causing backscattering, and also causing a phase change to provide information on blood components.

[0053] The analysis results for the dimension L51 = 0.45-0.70 mm shown in Figures 8 and 9 are similar to those commonly seen for simple planar boundaries. This shows that quarter-wave impedance matching is effective even for biological tissues with complex structures. It also shows that the backscattered reflected electromagnetic wave S11 carries glucose concentration information (information indicating blood sugar level).

[0054] FIG. 10 is a diagram showing an example of a calculation result when the blood glucose level of the reflected electromagnetic wave S11 changes from 70 mg / dL to 150 mg / dL. FIG. 11 is a diagram showing an example of a calculation result when the blood glucose level of the reflected electromagnetic wave S11 changes from 70 mg / dL to 150 mg / dL. FIG. 10 shows the magnitude of the amplitude ratio of the amplitude at 150 mg / dL to the amplitude at 70 mg / dL by color intensity, and FIG. 11 shows a color map showing the magnitude of the phase shift of the phase at 150 mg / dL to the phase at 70 mg / dL by color intensity. In these color maps, the larger the absolute value of both positive and negative, the darker the color. Note that the difference between positive and negative colors cannot be shown in the drawings, so the letters "positive" and "negative" are shown near each value.

[0055] The amplitude ratio shown in Fig. 10 and the phase shift shown in Fig. 11 compare the measurement result when the blood glucose concentration in the human body 3 is 70 mg / dL with the measurement result when the blood glucose concentration in the human body 3 is 150 g / dL. In both of the color maps in Fig. 10 and Fig. 11, the vertical axis indicates the dimension L51 (thickness, in mm) of the first dielectric 51 in the radiation direction D1, and the horizontal axis indicates the frequency of the electromagnetic wave (in GHz).

[0056] The amplitude ratio and phase shift in the vicinity of frequency = 86 to 88 GHz are -0.04 dB and 0.09 deg, respectively, when L51 = 0 (no paraffin), but in the region of L51 = 0.45 mm to 0.70 mm, both are larger. For example, when L51 = 0.45 mm and frequency = 86 GHz, the amplitude ratio is 2.74 dB, and when L51 = 0.45 mm and frequency = 88 GHz, the phase shift is -13.2 deg. In this way, by 1 / 4 wavelength impedance matching, the sensitivity to blood glucose concentration is improved by 2.7 dB in the case of amplitude ratio from |-0.04| dB to 2.74 dB, and in the case of phase shift from 0.09 deg to |-13.20| deg, improving by 147 times.

[0057] 5. Summary of configuration As described above, in the case of measuring either the reflected electromagnetic wave S11 or the transmitted electromagnetic wave S21, the measurement device 30 includes a radiation unit 31, a first waveguide 41, a first dielectric 51, and a measurement unit 32, as shown in Fig. 5 and Fig. 6. The first waveguide 41 is configured to be capable of transmitting electromagnetic waves in the microwave band or the millimeter wave band. The radiation unit 31 is disposed at one end (first end 411) of the first waveguide 41 and configured to radiate electromagnetic waves.

[0058] The first dielectric 51 is disposed at the other end (second end 412) of the first waveguide 41 and configured to be able to transmit electromagnetic waves. The measuring unit 32 is disposed at a position where the electromagnetic waves transmitted through the first dielectric 51 and the measurement site 4 reach when the first dielectric 51 is in close contact with the measurement site 4 of the human body 3, and configured to be able to measure the reaching electromagnetic waves. In the example of Fig. 5, the measuring unit 32 is disposed at a position where the transmitted electromagnetic wave S21 reaches, and in the example of Fig. 6, the measuring unit 32 is disposed at a position where the reflected electromagnetic wave S11 reaches.

[0059] In either case, the measurement results in Figures 8 and 9 show that impedance matching occurs due to the first dielectric 51 even in biological tissue with a complex structure, such as the measurement site 4 of the human body 3, so that it is possible to make it easier for electromagnetic waves to penetrate the measurement site 4 compared to the case where the first dielectric 51 is not provided, and as a result, the measurement accuracy of blood components using electromagnetic waves can be improved.

[0060] 5, in the case of measuring the transmitted electromagnetic wave S21, the measuring device 30 further includes a second dielectric 52 and a second waveguide 42. The second dielectric 52 is disposed at a position where the electromagnetic wave (transmitted electromagnetic wave S21) arrives via the first dielectric 51 and the measurement site 4 of the human body 3. The second waveguide 42 is configured to be capable of transmitting the electromagnetic wave. The second dielectric 52 is disposed at one end (first end 421) of the second waveguide 42, and the measuring unit 32 is disposed at the other end (second end 422) of the second waveguide 42. The measuring unit 32 is configured to measure the electromagnetic wave (transmitted electromagnetic wave S21) transmitted through the second waveguide 42.

[0061] According to this embodiment, impedance matching is also achieved by the second dielectric 52, so that, compared to a case in which the second dielectric 52 is not provided, the electromagnetic waves reflected at the boundary between the inside and outside of the measurement site 4 can be reduced, the transmitted electromagnetic waves S21 emitted from the measurement site 4 can be increased, and the measurement accuracy using the transmitted electromagnetic waves S21 can be improved.

[0062] 10 and 11, the improvement in sensitivity to blood glucose concentration due to quarter-wavelength impedance matching was greater in the range of ±30% of the central dimension L51 than in other ranges. Therefore, it is preferable that the first dielectric 51 is configured so that the dimension in the propagation direction of the electromagnetic wave (radiation direction D1) is within the range of ±30% of a quarter of the wavelength of the electromagnetic wave inside the first dielectric 51. According to this embodiment, the measurement accuracy of blood components can be improved compared to when the dimension L51 of the first dielectric 51 is outside this range.

[0063] The first dielectric 51 has an impedance Z m The impedance Z1 of the measurement site 4 of the human body 3 and the impedance Z2 of the first waveguide 41 are expressed by the above-mentioned formula (1). JPEG2025016381000004.jpg737. As described above, this range of impedance Zm is more likely to produce 1 / 4 wavelength impedance matching than when the impedance Zm is outside this range. Therefore, according to this embodiment, the measurement accuracy of blood components can be improved compared to when the impedance relationship is different from the above.

[0064] Similarly to the first dielectric 51, the second dielectric 52 is also preferably configured so that the dimension in the radiation direction D1 is within the range of ±30% of a quarter of the wavelength of the electromagnetic wave inside the second dielectric 52. Also, the second dielectric 52 is configured so that the relationship between the impedance of the measurement site 4 of the human body 3 and the second waveguide 42 is similar to the above formula (1) (the impedance of the second dielectric 52 is Z mThis makes it possible to improve the measurement accuracy of the blood components, similarly to the first dielectric 51.

[0065] Moreover, the blood component measuring system 1 includes a measuring device 30, an acquiring unit, and an output unit. The acquiring unit and the output unit are functions realized by a processor included in the blood component measuring system 1, and are realized, for example, by a processor included in the control unit 11 of the server device 10. The server device 10 (an example of an acquiring unit) acquires the measurement results measured by the measuring device 30, for example, in A21 (acquiring step) shown in FIG.

[0066] Furthermore, the server device 10 (an example of an output section) outputs component information indicating the blood components of the subject based on the acquired measurement results, for example, in A22 to A24 (output steps) shown in FIG. 7. In the example of FIG. 7, the server device 10 outputs information indicating the blood glucose level as the component information. The component information is output to, for example, the user terminal 20. According to this embodiment, the measurement device 30 is used to allow electromagnetic waves to easily penetrate the measurement site, and the measurement results are used to improve the measurement accuracy of the blood components.

[0067] The server device 10 (an example of an output unit) is constructed by machine learning using actual measured values ​​of blood components linked to the feature quantities of the measurement results as teacher data. The server device 10, for example, causes an estimator that performs adaptive estimation using a complex-valued neural network as described above to perform machine learning.

[0068] <Example of change: Impedance adjustment function> In the measurement device 30, the impedance Z of the dielectric 50 m depends on the impedance Z2 of the measurement site 4 of the human body 3. The impedance of the measurement site 4 of the human body 3 may vary among individuals, between measurement sites 4, or between physical conditions. Therefore, the measuring device 30 may have an adjustment function capable of adjusting the impedance according to differences or fluctuations in the impedance of the measurement site 4 of the human body 3.

[0069] 12 is a diagram showing a measuring device 30a having an adjustment function. The measuring device 30a further includes a first adjustment unit 53 in addition to the units shown in FIG. 6. The first adjustment unit 53 is configured to be able to adjust the dimension L51 of the first dielectric 51 in the radiation direction D1. The first adjustment unit 53 has a structure for holding, for example, an arbitrary number of paraffin sheets in a stack and contacting and fixing them to the second end 412 of the first waveguide 41.

[0070] For example, in the example of FIG. 12(a), the first adjustment unit 53 fixes a number of paraffin sheets whose dimension in the radial direction D1 is L51, as in FIG. 5 and the like. Also, in the example of FIG. 12(b), the first adjustment unit 53 fixes a number of paraffin sheets whose dimension in the radial direction D1 is L51a, which is larger than L51. The first dielectric with the dimension L51a is referred to as the first dielectric 51a. The first dielectric 51a has an impedance Z m The paraffin sheet is configured so that the dimension L51a satisfies the above-mentioned formula (1) and the dimension L51a satisfies the above-mentioned formula (2).

[0071] Therefore, the paraffin sheet added to the first dielectric 51 is not necessarily the same as the paraffin sheet that the first dielectric 51 has. Also, the paraffin sheet that the first dielectric 51 has may be removed and replaced with another set of paraffin sheets. Also, the first adjustment unit 53 may be capable of adjusting the dimension L51 of the first dielectric 51 in three or more stages. Also, the first adjustment unit 53 may be capable of continuously adjusting the thickness of the paraffin sheet by compressing or stretching it. According to such an embodiment, the measurement accuracy of blood components can be improved even if there are individual differences or changes in physical condition.

[0072] FIG. 13 is a diagram showing a measuring device 30b having an adjustment function. The measuring device 30b further includes a second adjustment unit 54 in addition to the units shown in FIG. 6. The second adjustment unit 54 is configured to be able to adjust the impedance of the first dielectric 51. The second adjustment unit 54 has a structure in which any type of paraffin sheet is stacked and held, similar to the first adjustment unit 53, and fixed in contact with the second end 412 of the first waveguide 41. For example, in the example of FIG. 13(a), the second adjustment unit 54 adjusts the impedance to Z in the same manner as in FIG. 5 and the like. m A paraffin sheet of the type shown is fixed in place.

[0073] In the example of FIG. 13(b), the second adjustment unit 54 adjusts the impedance Z m A paraffin sheet of the type b is fixed. Impedance Z m The first dielectric 51b has an impedance Z m The paraffin sheet is configured so that b satisfies the above-mentioned formula (1) and the dimension L51 satisfies the above-mentioned formula (2). According to this embodiment, the measurement accuracy of blood components can be improved even if there are individual differences or changes in physical condition.

[0074] FIG. 14 is a diagram showing a measuring device 30c having an adjustment function. The measuring device 30c further includes a third adjustment unit 55 in addition to the units shown in FIG. 6. The third adjustment unit 55 is configured to be able to adjust the frequency of the electromagnetic waves emitted by the emission unit 31. The third adjustment unit 55 is, for example, electrically connected to the emission unit 31 and has an adjustment dial for adjusting the frequency. When a user performing a measurement operates the adjustment dial to specify a frequency, the third adjustment unit 55 supplies a request signal to the emission unit 31 requesting that the electromagnetic waves be output at the specified frequency. The emission unit 31 emits the electromagnetic waves at the frequency indicated by the supplied request signal.

[0075] For example, in the example of Fig. 14(a), the radiation unit 31 radiates electromagnetic waves at a frequency F1. In the example of Fig. 14(b), the third adjustment unit 55 supplies a request signal to the radiation unit 31 to set the frequency to F1c, and the radiation unit 31 radiates electromagnetic waves at the frequency F1c. When the frequency of the electromagnetic waves changes, the dimension L51 (thickness) of the first dielectric 51, which improves the blood glucose measurement sensitivity, changes as shown in Figs. 10 and 11. For example, when the frequency is 60 GHz, the sensitivity is high when the thickness is 0.66 mm, but when the frequency is 90 GHz, the sensitivity is high when the thickness is 0.45 mm.

[0076] The frequency at which sensitivity is high changes when the dimension L51 (thickness) of the first dielectric 51 is adjusted as in the example of Fig. 12, or when the impedance of the first dielectric 51 is adjusted as in the example of Fig. 13. In that case, the measurement accuracy of the blood components can be improved by adjusting the frequency of the electromagnetic waves by operating the third adjustment unit 55. Even if the dimension L51 or impedance is not adjusted, the frequency at which sensitivity is high may change due to differences or changes in the impedance of the measurement site 4 of the human body 3. In that case, too, the measurement accuracy of the blood components can be improved by adjusting the frequency.

[0077] 12 to 14 are not limited to the above. For example, the first adjustment section 53 and the second adjustment section 54 may be integrated with the first dielectric 51, and the third adjustment section 55 may be integrated with the radiation section 31. The first adjustment section 53 and the second adjustment section 54 may be provided in one or both of the first dielectric 51 and the second dielectric 52.

[0078] <Example of change: Waveguide> The measuring device 30 may not include the waveguide 40 (the first waveguide 41 and the second waveguide 42). Even if the first waveguide 41 is not included, the electromagnetic waves emitted from the radiating unit 31 may be transmitted through the air and may be incident on the measurement site 4 of the human body 3 via the first dielectric 51. Also, even if the second waveguide 42 is not included, the measuring unit 32 may be disposed at a position where the electromagnetic waves emitted from the second dielectric 52 via the measurement site 4 of the human body 3 reach. In either case, reflection at the boundary between the measurement site 4 and the dielectric 50 is suppressed compared to the case where the dielectric 50 is not included, and the measurement accuracy of blood components by electromagnetic waves can be improved.

[0079] When the waveguide 40 is not provided, the electromagnetic wave radiated from the radiation portion 31 is transmitted not through the first waveguide 41 but through a region in contact with the first dielectric 51 upstream of the first dielectric 51 (hereinafter referred to as the "upstream region"). In this case, when the impedance of the upstream region of the first dielectric 51 is Z2, the impedance Z m and the impedance Z1 of the measurement site 4 of the human body 3 is expressed by the above-mentioned formula (1). It is sufficient that the image is configured to satisfy JPEG2025016381000005.jpg737.

[0080] It has been experimentally found that quarter-wave impedance matching occurs even if the impedance relationship varies within the range expressed by formula (1). Therefore, the measurement accuracy of blood components can be improved compared to when formula (1) is not satisfied. In addition, the second dielectric 52 is also configured so that the impedance relationship satisfies formula (1) when the impedance of the region in contact with the second dielectric 52 downstream of the second dielectric 52 (hereinafter referred to as the "downstream region") is Z2.

[0081] The impedance Z of the dielectric 50 (the first dielectric 51 and the second dielectric 52) mis not limited to the range of ±30% shown in formula (1), and may be limited to the range of, for example, ±1%, ±2%, ±3%, ±4%, ±5%, ±6%, ±7%, ±8%, ±9%, ±10%, ±11%, ±12%, ±13%, ±14%, ±15%, ±16%, ±17%, ±18%, ±19%, ±20%, ±21%, ±22%, ±23%, ±24%, ±25%, ±26%, ±27%, ±28%, ±29%. In either case, the impedance Z m Compared to when the electromagnetic wave is outside this range, reflection of the electromagnetic wave at the boundary surface is suppressed, and the measurement accuracy of the blood components can be improved.

[0082] <Example of variation: Dielectric composition> When measuring the transmitted electromagnetic wave S21, the second dielectric 52 is not necessarily required. Even without the second dielectric 52, the reflection on the body surface of the human body 3 is suppressed by impedance matching by the first dielectric 51, so that the electromagnetic wave can more easily penetrate into the measurement site 4 compared to the case where the first dielectric 51 is not provided.

[0083] Furthermore, the dimension of the dielectric 50 (the first dielectric 51 and the second dielectric 52) in the radial direction D1 is not limited to within a range of ±30% of a quarter of the wavelength of the electromagnetic wave inside the dielectric 50, and may be limited to a range of, for example, ±1%, ±2%, ±3%, ±4%, ±5%, ±6%, ±7%, ±8%, ±9%, ±10%, ±11%, ±12%, ±13%, ±14%, ±15%, ±16%, ±17%, ±18%, ±19%, ±20%, ±21%, ±22%, ±23%, ±24%, ±25%, ±26%, ±27%, ±28%, ±29%. In either case, impedance matching is more likely to occur than when the dimension of the dielectric 50 in the radial direction D1 is outside that range, and the measurement accuracy of blood components can be improved.

[0084] <Example of change: Position of measurement part> The position of the measuring unit 32 is not limited to the position shown in Fig. 5 and Fig. 6. For example, in the example of Fig. 5, the measuring unit 32 is disposed on an extension of the radiation direction D1, but the measuring unit 32 may be disposed at a position shifted from the radiation direction D1. Also, in the example of Fig. 6, the measuring unit 32 is disposed in the reflection direction D2 opposite to the radiation direction D1, but the measuring unit 32 may be disposed at a position shifted from the reflection direction D2. In short, the measuring unit 32 may be disposed in any direction as long as it is a direction in which the electromagnetic waves scattered by blood or the like reach. However, it is desirable to dispose the measuring unit 32 in a direction in which as many scattered electromagnetic waves as possible reach.

[0085] <Example of change: Configuration of communication section> The communication unit 33 is not limited to the above configuration. For example, the communication unit 33 may transmit the measurement data directly to the server device 10, instead of the user terminal 20. Also, the measurement device 30 may be provided with the acquisition unit and output unit provided in the server device 10, thereby making the communication unit 33 unnecessary. In this case, the measurement device 30 can independently measure blood components and output component information indicating the measured blood components.

[0086] <Example of change: Blood components> The blood components measured by the blood component measuring system 1 are not limited to glucose (sugar). For example, the blood component measuring system 1 may be configured to measure blood lipids or blood salt concentration. By measuring blood lipids, it is possible to predict the risk of cerebrovascular disease and the like by a non-invasive method that places little physical strain on the human body 3. Note that "measurement" of blood components may also be referred to as "measurement," "detection," "sensing," "estimation," and the like.

[0087] <Examples of variations: composition variations> The configuration (overall configuration, hardware configuration, functional configuration, etc.) shown in Fig. 1 etc. is an example, and other configurations may be used as long as there is no inconvenience in implementation. For example, the server device 10 may be distributed across two or more devices, and may be provided in the form of SaaS (Software as a Service) or a cloud computing system, etc. In short, as long as the necessary information processing is performed in the entire blood component measurement system 1, the devices that execute this information processing may have any configuration.

[0088] The output destination of information or data (hereinafter referred to as "information, etc.") may be another device, a display, a memory unit (including a built-in memory unit and an external memory unit), an email address, an account of another system, etc. Acquisition of information, etc. includes acquisition of information, etc. generated by the device itself, in addition to acquisition of information, etc. transmitted from another device. Tables, etc. (tables, databases, etc.) in which parameters are associated are not limited to the tables, etc. shown in the figures, and the number of parameters may be reduced or increased. Furthermore, information, etc. corresponding to parameters may be obtained by a formula, a conditional formula, etc. without using a table, etc.

[0089] The above-mentioned aspects of the embodiment are information processing devices such as the server device 10 and the user terminal 20, and information processing systems such as the blood component measurement system 1 including the server device 10 and the user terminal 20, but may also be information processing methods. The information processing method includes the same steps as those executed by the information processing system. The above-mentioned aspects of the embodiment may also be programs. The program causes a computer to execute the same steps as those executed by the information processing system.
