Mode for Carrying Out the Invention

[0009] Hereinafter, an embodiment will be described with reference to the drawings. The physical health calculation system 10 of the embodiment shown in FIG. 1 is, for example, a system for calculating the health of the blood vessel wall 90 of an artery of a living body, that is, a user with no disease. The health of the blood vessel wall 90 of the artery is greatly related to the physical health. In this specification, the physical health calculation system 10 may be simply referred to as the calculation system 10. The calculation system 10 can be configured by combining a plurality of dedicated or general-purpose devices connected via a telecommunication line such as a LAN line or an Internet line, or can also be configured by installing a physical health calculation program in one device.

[0010] The calculation system 10 can be configured to include a biological information measurement device 20, an activation device 30, and a processing device 40. The biological information measurement device 20 and the activation device 30 are configured to be communicable with the processing device 40 by wire or wirelessly. The biological information measurement device 20 is a device for measuring the tonus information of the blood vessel wall 90. The tonus information is biological information indicating the correspondence between blood vessel pressure and blood vessel volume. The blood vessel pressure means the pressure acting on the blood vessel wall 90 in a direction to expand the blood vessel wall 90. The blood vessel pressure can be obtained, for example, by "(pressure externally applied to the blood vessel wall 90) - (blood pressure)". The blood vessel volume means the volume inside the blood vessel wall 90.

[0011] Here, as shown in FIG. 2, the blood vessel wall 90 has a three-layer structure composed of an intima 91, a media 92, and an adventitia 93. The intima 91 is the innermost layer of the blood vessel wall 90. Receptors (not shown) for detecting the state of blood exist on the vascular endothelial cells of the intima 91. The media 92 is the layer located between the intima 91 and the adventitia 93. Smooth muscle 921 exists in the media 92.

[0012] As the receptors of the intima 91 sense vascular acting factors in the blood, the state of the smooth muscle 921 changes between a tense state and a relaxed state. The smooth muscle 921 has a function of adjusting the elasticity of the blood vessel wall 90. The blood vessel wall 90 is activated, for example, by appropriate stimulation to the human body such as exercise or drugs. And in a state where the blood vessel wall 90 is not activated, that is, in a state where the original flexibility of the blood vessel wall 90 is not exerted, the smooth muscle 921 is in a tense state. On the other hand, in a state where the blood vessel wall 90 is activated, that is, in a state where the original flexibility of the blood vessel wall 90 is exerted, the smooth muscle 921 is in a relaxed state. The adventitia 93 is the outermost layer of the blood vessel wall 90.

[0013] As shown in FIG. 3, the biological information measuring device 20 can be configured to include a compression band 21, a pump 22, a control valve 23, various sensors 24, a communication unit 25, and a measurement-side control unit 26. The compression band 21 is composed of a so-called cuff and is a bag-shaped member that can be wound around a part of the human body, for example, the upper arm. The compression band 21 is configured to be able to supply air inside, and in a state of being wound around the upper arm of the human body, it can receive air supplied from the pump 22 and compress the upper arm, for example.

[0014] The pump 22 is connected to the compression band 21 via the pipe 221. In this case, the pump 22 supplies air into the compression band 21 via the pipe 221. The pipe 221 is composed of, for example, a flexible tubular member. The control valve 23 is, for example, an on-off valve that can be opened and closed electromagnetically. The control valve 23 is for adjusting the amount of air supplied from the pump 22 to the compression band 21. That is, the internal pressure of the compression band 21 is adjusted by the control valve 23. The various sensors 24 are composed of, for example, a pressure sensor, a flow rate sensor, and the like. The pressure sensor can measure, for example, the internal pressure of the compression band 21. The flow rate sensor can measure, for example, the flow rate of the air supplied to the compression band 21. Although not shown in detail, the flow rate sensor is provided midway between the control valve 23 and the compression band 21 in the pipe 221 connecting the compression band 21 and the pump 22.

[0015] The communication unit 25 is an interface for communicating with the activation device 30 and the processing device 40, respectively, by wire or wirelessly. The measurement-side control unit 26 is mainly composed of, for example, a CPU and a microcomputer having storage areas such as a ROM and a RAM, and controls the entire biological information measuring device 20. The measurement-side control unit 26 controls the biological information measuring device 20 by executing a program stored in the storage area. The pump 22, the control valve 23, the various sensors 24, and the communication unit 25 are electrically connected to the measurement-side control unit 26. The measurement-side control unit 26 controls the operations of the pump 22 and the control valve 23 to change the internal pressure of the compression band 21, that is, to increase or decrease the internal pressure. Various functional units such as a data acquisition unit 27 and a calculation unit 28 are provided in the measurement-side control unit 26. Note that a part or all of the data acquisition unit 27 and the calculation unit 28 may be provided in the activation device 30 or the processing device 40.

[0016] The data acquisition unit 27 can execute time-series data acquisition processing. The time-series data acquisition processing includes processing for acquiring time-series data. The time-series data indicates the respective changes in the internal pressure and the volume of the compression band 21 during a period in which the internal pressure of the compression band 21 is changing. In this case, the data acquisition unit 27 acquires time-series data by sampling the internal pressure and the volume of the compression band 21 at a predetermined cycle during a period in which the internal pressure of the compression band 21 is gradually decreasing. The volume of the compression band 21 means the volume of the compression band 21 calculated based on the measured value of the flow sensor.

[0017] The calculation unit 28 can execute calculation processing. The calculation processing includes processing for calculating tonus information. In this case, the calculation unit 28 performs processing for calculating tonus information based on the time-series data acquired by the data acquisition unit 27. As the method for calculating the tonus information, the method described in Japanese Patent Application Laid-Open No. 2020-160493 can be used.

[0018] The activation device 30 is a device for activating the blood vessel wall 90. The activation device 30 has a function of improving the vascular endothelial function of the blood vessel wall 90. Improving the vascular endothelial function means activating inactive blood vessels and includes activating the blood vessel wall 90 and improving blood flow. Also, in a state where the vascular endothelial function is improved, the flexibility of the blood vessel is improved. As shown in FIG. 4, the activation device 30 includes a pulsation detection compression band 31, a blood pumping compression band 32, a compressor 33, a plurality of ventilation valves 341, 342, a plurality of exhaust valves 351, 352, a pulsation detector 36, a communication unit 37, and an active side control unit 38. The pulsation detection compression band 31 can detect pulsations, for example, by being wound around the limbs, and is for detecting the blood pumping state by the blood pumping compression band 32. The pulsation detection compression band 31 is configured to be able to supply air inside, and in a state of being wound around the limbs, receives the air supplied from the compressor 33 and pressurizes the limbs.

[0019] The blood-expelling compression band 32 is composed of a so-called cuff, which is a bag-shaped member that can be wound around a part of the human body, for example, the limbs. The blood-expelling compression band 32 is configured to be able to supply air inside, and in a state of being wound around the limbs, it can receive the air supplied from the compressor 33 and compress the limbs. The blood-expelling compression band 32 is used by being wound around a position closer to the heart than the pulsation-detecting compression band 31. The blood-expelling compression band 32 has a function of expelling blood. The compressor 33 is connected to the pulsation-detecting compression band 31 and the blood-expelling compression band 32 by pipes 331 and 332 respectively. The compressor 33 supplies air into the pulsation-detecting compression band 31 and the blood-expelling compression band 32 through the pipes 331 and 332. The pipes 331 and 332 are composed of, for example, flexible tubular members.

[0020] The plurality of ventilation valves 341 and 342 are, for example, on-off valves that can be opened and closed electromagnetically. The ventilation valve 341 is provided on the pipe 331 and opens and closes the air flow path supplied to the pulsation-detecting compression band 31 by the compressor 33. Also, the ventilation valve 342 is provided on the pipe 332 and opens and closes the air flow path supplied to the blood-expelling compression band 32 by the compressor 33. In this specification, the ventilation valve 341 may be referred to as the first ventilation valve 341, and the ventilation valve 342 may be referred to as the second ventilation valve 342. A pressure-regulating valve (not shown) is provided between the compressor 33 and the ventilation valves 341 and 342. The pressure-regulating valve is for adjusting the pressure of the air supplied from the compressor 33 to a predetermined pressure.

[0021] The plurality of exhaust valves 351 and 352 are, for example, on-off valves that can be opened and closed electromagnetically. The exhaust valve 351 is located in the middle part of the pipe 331, between the first ventilation valve 341 and the pulsation detection compression band 31. The exhaust valve 351 is provided at a branched portion of the pipe 331. The exhaust valve 351 is for discharging the air in the pulsation detection compression band 31 to the outside. The exhaust valve 352 is located in the middle part of the pipe 332, between the second ventilation valve 342 and the blood pumping compression band 32. The exhaust valve 352 is provided at a branched portion of the pipe 332. The exhaust valve 352 is for discharging the air in the blood pumping compression band 32 to the outside. In this specification, the exhaust valve 351 may be referred to as the first exhaust valve 351, and the exhaust valve 352 may be referred to as the second exhaust valve 352.

[0022] The pulsation detector 36 is constituted by, for example, a strain gauge or the like and can detect vibrations based on pulsations. The pulsation detector 36 is located, for example, on the downstream side of the pulsation detection compression band 31. Downstream means the downstream in the flow path direction of the air flowing through the pipe 332. The communication unit 37 is an interface that communicates with the biological information measuring device 20 and the processing device 40, either wired or wirelessly.

[0023] The active side control unit 38 is mainly constituted by, for example, a CPU or a microcomputer having a storage area such as a ROM and a RAM, and controls the entire activation device 30. The active side control unit 38 controls the activation device 30 by executing a program stored in the storage area. The compressor 33, the ventilation valves 341 and 342, the exhaust valves 351 and 352, the pulsation detector 36, and the communication unit 37 are electrically connected to the active side control unit 38.

[0024] Next, with reference to FIG. 5, an example of the control content executed by the active side control unit 38 will be described. The control content shown in FIG. 5 is executed on the premise that the pulsation detection compression band 31 and the blood expulsion compression band 32 are wound around the limbs of the human body. The control content executed by the active side control unit 38 corresponds to the activation process. The activation process includes a process of repeatedly performing an activation operation a plurality of times, for example, 3 times until a predetermined time, for example, 6 minutes, is reached. Thereby, an appropriate stimulus can be applied to the blood vessel wall 90, so that the blood vessel wall 90 changes to a state in which flexibility is exhibited, that is, a state in which the vascular endothelial function of the blood vessel wall 90 is improved. The activation operation is to pressurize the blood expulsion compression band 32 during the period when the pulsation detector 36 detects the vibration based on the pulsation generated by the pressurization of the pulsation detection compression band 31, and then, after a certain time has elapsed since the pulsation detector 36 stops detecting the vibration, depressurize the pulsation detection compression band 31 and the blood expulsion compression band 32 to provide a rest time.

[0025] Specifically, as shown in FIG. 5, when starting the control, the active side control unit 38 opens the first ventilation valve 341 and pressurizes the pulsation detection compression band 31 in step S11. Next, the active side control unit 38 determines in step S12 whether the pulsation detector 36 has detected a pulsation. When a pulsation is detected (YES in step S12), the active side control unit 38 opens the second ventilation valve 342 and pressurizes the blood expulsion compression band 32 in step S13.

[0026] Thereafter, when the blood vessel wall 90 is in a blood expulsion state due to the pressurization of the blood expulsion compression band 32 and the blood flow stops, the pulsation detector 36 stops detecting the pulsation. The active side control unit 38 determines in step S14 whether the pulsation detector 36 is not detecting a pulsation. When no pulsation is detected (NO in step S14), the active side control unit 38 closes the second ventilation valve 342, stops the pressurization of the blood expulsion compression band 32, and maintains a certain pressure state in step S15.

[0027] Next, in step S16, the active side control unit 38 determines whether or not a predetermined time T1, for example, one minute and 30 seconds, has elapsed since the blood expulsion state of the blood vessel wall 90. When the blood expulsion state has elapsed for the predetermined time T1 (YES in step S16), the active side control unit 38 closes the first ventilation valve 341 and stops pressurizing the pulsation detection compression band 31 in step S17.

[0028] Thereafter, in step S18, the active side control unit 38 opens the exhaust valves 351 and 352 for a certain period of time to exhaust, that is, depressurize, the air in the pulsation detection compression band 31 and the blood expulsion compression band 32. Next, in step S19, the active side control unit 38 determines whether or not a predetermined time T2, for example, 30 seconds, has elapsed since the air in the pulsation detection compression band 31 and the blood expulsion compression band 32 was exhausted. The predetermined time T2 corresponds to the rest time.

[0029] When the predetermined time T2 has elapsed since the air in the pulsation detection compression band 31 and the blood expulsion compression band 32 was exhausted (YES in step S19), the active side control unit 38 determines in step S20 whether or not an active time Ta, for example, six minutes, which is the elapsed time since the first ventilation valve 341 was opened after starting the control, has elapsed. When the active time Ta has not elapsed (NO in step S20), the active side control unit 38 transfers the process to step S11 and executes the subsequent process. On the other hand, when the active time Ta has elapsed (YES in step S20), a series of controls is terminated (end). Note that the method of activating the blood vessel wall 90 is not limited to the method of expelling blood from the blood vessel wall 90, and other methods such as applying low-temperature heat or vibration to the human body may be adopted or used in combination.

[0030] The processing device 40 is composed of, for example, a personal computer, a tablet terminal, a server device, etc. The processing device 40 is an example of a computer. The processing device 40 is a device that performs various data processes. The processing device 40 is communicably connected to each of the biological information measuring device 20 and the activation device 30, either by wire or wirelessly. In this case, as shown in FIG. 1, the processing device 40 has a control unit 41. The control unit 41 is mainly composed of, for example, a CPU 411 and a microcomputer having a storage area 412 such as a ROM and a RAM, and controls the entire processing device 40.

[0031] The storage area 412 of the control unit 41 stores all or part of a program for applying the processing device 40 to the calculation system 10. In this case, it stores all or part of the physical health degree calculation program. The pre-activation calculation information acquisition unit 51, the activation processing unit 52, the post-activation calculation information acquisition unit 53, and the difference calculation processing unit 54 are realized by the CPU 411 of the control unit 41 executing a computer program stored in the storage area 412 and performing the processing corresponding to the computer program, that is, realized by software. And the pre-activation calculation information acquisition unit 51, the activation processing unit 52, the post-activation calculation information acquisition unit 53, and the difference calculation processing unit 54 are virtually realized by software by the CPU 411 executing the physical health degree calculation program stored in the storage area 412. Note that part or all of the control unit 41, the pre-activation calculation information acquisition unit 51, the activation processing unit 52, the post-activation calculation information acquisition unit 53, and the difference calculation processing unit 54 may be provided in the biological information measuring device 20 or the activation device 30.

[0032] The pre-activation calculation information acquisition unit 51 can execute pre-activation calculation information acquisition processing. The pre-activation calculation information acquisition processing includes a process of acquiring the tonus information L1 calculated by the calculation unit 28 of the biological information measurement device 20. The activation processing unit 52 can execute activation processing. The activation processing 52 is executed after the pre-activation calculation information acquisition processing and includes a process of improving the vascular endothelial function of the blood vessel wall 90 using the activation device 30. The post-activation calculation information acquisition unit 53 can execute post-activation calculation information acquisition processing. The post-activation calculation information acquisition processing is executed after the activation processing and includes a process of acquiring the tonus information L2 calculated by the calculation unit 28 of the biological information measurement device 20 after the activation processing. The difference calculation processing unit 54 can execute difference calculation processing. The difference calculation processing includes a process of calculating the difference ΔL between the tonus information L2 calculated by the post-activation calculation processing and the tonus information L1 calculated by the pre-activation calculation processing.

[0033] Here, FIG. 6 shows the relationship between the tonus information L1 calculated before the activation processing and the tonus information L2 calculated after the activation processing. The graph shown in FIG. 6 shows the vascular volume on the horizontal axis and the vascular pressure on the vertical axis. The tonus information L1 calculated before the activation processing indicates, for example, the value of the correspondence relationship between the vascular volume and the vascular pressure in a state where the smooth muscle 921 of the blood vessel wall 90 is in a tense state, for example, and the original flexibility of the blood vessel wall 90 is not exerted. In other words, the tonus information L1 indicates the value of the correspondence relationship between the vascular volume and the vascular pressure of the user in the normal state. When an appropriate stimulus is applied to the human body by the activation processing, the smooth muscle 921 of the blood vessel wall 90 becomes, for example, a relaxed state, and the original flexibility of the blood vessel wall 90 is exerted, that is, the state where the vascular endothelial function of the blood vessel wall 90 is improved. That is, the tonus information L2 indicates the value of the correspondence relationship between the vascular volume and the vascular pressure in a state where the original flexibility of the blood vessel wall 90 is exerted, that is, the state where the vascular endothelial function of the blood vessel wall 90 is improved.

[0034] By calculating the difference ΔL between the tone information L2 and the tone information L1, it is possible to compare the state in which the user's blood vessel wall 90 exhibits its original flexibility with the state of the blood vessel wall 90 in normal times. Thereby, the health of the blood vessel wall 90 can be evaluated using the difference ΔL. That is, the smaller the difference ΔL, the more favorably the health of the user's blood vessel wall 90 can be evaluated. On the other hand, the larger the difference ΔL, the more unfavorably the health of the user's blood vessel wall 90 can be evaluated. Based on the evaluation of the health of the blood vessel wall 90, the user can, for example, improve their health and lifestyle without undergoing tests and examinations at a hospital.

[0035] Here, when the body shows a normal reaction to a stimulus, the difference ΔL indicates a positive number. On the other hand, when the difference ΔL indicates a negative number, it can be said that the user is having an excessive reaction to stimuli such as fatigue and stress. Therefore, if the state where the difference ΔL indicates a negative number continues, diagnosis at a hospital or the like is recommended. Note that the health can be determined based on whether the tone information L1 and L2 measured with respect to the reference value of the tone information of the health state are satisfied. For example, when the tone information L1 does not reach the reference value and the tone information L2 is satisfied, there is no problem with the performance of the blood vessel wall 90, but there is a problem with the current state, that is, the current situation, and it can be said that the lifestyle needs to be reviewed. Also, when neither the tone information L1 nor the tone information L2 reaches the reference value, for example, treatment and diagnosis at a hospital are recommended.

[0036] Hereinafter, with reference to FIG. 7, an example of the control content of the calculation system 10 will be described. Note that the control content shown in FIG. 7 is executed on the premise that the compression band 21, the pulsation detection compression band 31, and the blood expulsion compression band 32 are wound around the human body. As shown in FIG. 7, when the control is started (start), the pre-activation calculation step (step A11), the pre-activation calculation information acquisition step (step A12), the activation step (step A13), the post-activation calculation step (step A14), the post-activation calculation information acquisition step (step A15), and the difference calculation step (step A16) are processed in this order.

[0037] First, when the biological information measurement device 20 receives an instruction from the processing device 40 to execute a calculation process in step A11, it calculates the tonus information L1 based on the time-series data obtained by controlling the operations of the pump 22 and the control valve 23 according to that instruction. Next, in step A12, the processing device 40 acquires the tonus information L1 calculated by the calculation unit 28. Then, when the activation device 30 receives an instruction from the processing device 40 to execute an activation process in step A13, it executes the activation process according to that instruction. Next, when the biological information measurement device 20 receives an instruction from the processing device 40 to execute a calculation process in step A14, it calculates the tonus information L2 based on the time-series data obtained by controlling the operations of the pump 22 and the control valve 23 according to that instruction.

[0038] Next, in step A15, the processing device 40 acquires the tonus information L2 calculated by the calculation unit 28. Then, in step A16, the processing device 40 calculates the difference ΔL between the tonus information L2 calculated by the post-activation calculation step and the tonus information L1 calculated by the pre-activation calculation step, and ends a series of controls (end).

[0039] According to the embodiment described above, the method for calculating physical health includes a pre-activation calculation step, an activation step, a post-activation calculation step, and a difference calculation step. The pre-activation calculation step calculates the tonus information L1 indicating the correspondence between the vascular pressure indicating the pressure applied to the blood vessel wall 90 of the living body and the vascular volume indicating the volume inside the blood vessel wall 90. The activation step is executed after the pre-activation calculation step and improves the vascular endothelial function of the blood vessel wall 90. The post-activation calculation step is executed after the activation step and calculates the tonus information L2 after the activation step. The difference calculation step calculates the difference ΔL between the tonus information L2 calculated by the post-activation calculation step and the tonus information L1 calculated by the pre-activation calculation step.

[0040] According to this, the current health condition of the blood vessel wall 90 can be easily calculated. As a result, the user himself / herself can evaluate the health condition of the blood vessel wall 90 in a pre-disease state, and can easily identify the factors affecting the physical health condition. As a result, it is possible to promote the user's health and improve their lifestyle.

[0041] The activation process includes a process of repeatedly performing the activation operation a plurality of times until a predetermined time is reached. The activation operation pressurizes the blood pumping compression band 32 that pumps blood through a part of the living body during the period when the pulsation detector 36 detects vibrations based on the pulsations generated by pressurizing the pulsation detection compression band 31 wrapped around a part of the living body, and then, after a certain time has passed since the pulsation detector 36 stops detecting vibrations, the pulsation detection compression band 31 and the blood pumping compression band 32 are depressurized to provide a rest time T2.

[0042] According to this, the vascular endothelial function of the blood vessel wall 90 can be improved by a simple method. As a result, the current health condition of the blood vessel wall 90 can be easily calculated.

[0043] The above embodiments are presented as examples and are not intended to limit the scope of the invention. This novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
