(Embodiment of physical condition monitoring device)
<1>
The physical condition monitoring apparatus according to the present embodiment includes a measurement unit that measures at least one of the blood pressure of the living body and the blood flow volume of the living body, an input unit that receives an input of a desired calculation parameter input from the outside, and the measurement unit measures And a physical condition calculation unit that calculates a physical condition risk level indicating the physical condition of the living body based on at least one of the blood pressure and the blood flow rate and the calculation parameter.

  According to the physical condition monitoring apparatus of the present embodiment, the measurement unit may measure the blood pressure of the living body. At this time, the measurement unit may discretely measure blood pressure. Specifically, the measurement unit may measure blood pressure for each first cycle. In other words, the measurement unit may measure blood pressure for each first cycle. More specifically, the measurement unit may measure blood pressure at the first timing. Thereafter, the measurement unit may measure the blood pressure again at the second timing when the period corresponding to the first period has elapsed from the first timing. Thereafter, the measurement unit may repeat the same operation.

  The measurement unit may measure the blood flow rate of the living body in addition to or instead of measuring the blood pressure of the living body. At this time, the measurement unit may continuously measure the blood flow. Specifically, the measurement unit performs blood flow for each second cycle (however, the second cycle is preferably shorter than the first cycle in which the measurement unit measures blood pressure). May be measured. In other words, the measurement unit may measure the blood flow for each second period. More specifically, the measurement unit may measure the blood flow rate at the third timing. Thereafter, the measurement unit may measure the blood flow rate again at the fourth timing when the period corresponding to the second period has elapsed from the third timing. Thereafter, the measurement unit may repeat the same operation.

  Particularly in the present embodiment, the input unit accepts input of desired calculation parameters input from the outside. Here, the “calculation parameter” of the present embodiment is an arbitrary index that is considered together with at least one of blood pressure and blood flow measured by the measurement unit when calculating a physical condition risk level described later. In particular, the calculated parameter is preferably an index different from the index measured by the measurement unit. Typically, the calculation parameter is an index manually input by the living body itself or a user of the physical condition monitoring device.

  In the present embodiment, in particular, the physical condition calculation unit calculates the physical condition risk level based on at least one of blood pressure and blood flow measured by the measurement unit and the calculation parameter received by the input unit. That is, instead of calculating the physical condition risk level based only on the blood pressure measured by the measurement unit, the physical condition calculation unit is based on each of the blood pressure measured by the measurement unit and the calculation parameter received by the input unit. Calculate the risk level. Or, instead of calculating the physical condition risk level based only on the blood flow measured by the measurement unit, the physical condition calculation unit is based on each of the blood flow measured by the measurement unit and the calculation parameter received by the input unit. To calculate the health risk level. In other words, instead of calculating the physical condition risk level based on only the blood pressure and blood flow measured by the measurement unit, the physical condition calculation unit calculates the blood pressure and blood flow measured by the measurement unit and the input unit receives input. A physical condition risk level is calculated based on each of the parameters.

  Here, the “physical condition risk level” indicates directly or indirectly whether or not the physical condition of the living body is good (or not), or the state of the physical condition of the living body. Means any indicator. An example of such a physical condition risk level is a numerical value that increases as the physical condition of the living body deteriorates.

  In such a physical condition monitoring apparatus of the present embodiment, not only the measurement value (that is, at least one of blood pressure and blood flow) measured by the measurement unit, but also the calculation parameter (for example, manually input) received by the input unit. The physical condition risk level can be calculated based on the calculated parameters. Therefore, the physical condition monitoring apparatus of the present embodiment is more suitable for the physical condition of the living body than the physical condition monitoring apparatus of the comparative example that calculates the physical condition risk level based only on the measurement value measured by the measurement unit (for example, more Can be monitored)

  From the viewpoint of more suitably monitoring the physical condition of the living body, it is preferable that the measuring unit measures both blood pressure and blood flow. Here, generally, the measured “blood flow” is often used as a relative value (that is, a relative value or a change amount with respect to some reference value). For this reason, although the physical condition monitoring device of the comparative example that monitors the physical condition based only on “blood flow” can determine whether or not the physical condition is suddenly changed by monitoring the change amount of the blood flow, etc. It is not possible to suitably determine the state of the physical condition at the stage before the physical condition suddenly changes. This is because the usefulness of the information as the absolute value of the blood flow itself is not relatively high. On the other hand, “blood pressure” is often used as an absolute value (that is, the value of blood pressure itself). However, the burden on the living body due to the measurement of “blood pressure” is larger than the burden on the living body due to the measurement of “blood flow”. For this reason, the physical condition monitoring device of the comparative example that monitors the physical condition based only on “blood pressure” cannot measure blood pressure frequently considering the burden on the living body due to the measurement of “blood pressure”. Therefore, the physical condition monitoring apparatus of the comparative example that monitors the physical condition based only on “blood pressure” cannot continuously determine the state of the physical condition. However, a physical condition monitoring device that measures both blood pressure and blood flow monitors physical condition based on both “blood pressure”, which is often used as an absolute value, and “blood flow”, which is often used as a relative value. can do. For this reason, the physical condition monitoring apparatus of the present embodiment compensates for the demerits occurring in the physical condition monitoring apparatus of the comparative example that monitors the physical condition based only on “blood pressure” by monitoring the physical condition based also on “blood flow”. Can do. Similarly, the physical condition monitoring device that measures both blood pressure and blood flow monitors the physical condition based on “blood pressure” and the disadvantages that occur in the physical condition monitoring device of the comparative example that monitors physical condition based only on “blood flow”. You can make up for it. Therefore, the physical condition monitoring device that measures both the blood pressure and the blood flow volume is more suitable for the physical condition of the living body than the physical condition monitoring device of the comparative example that calculates the physical condition risk level based on a single measurement value (for example, Can be monitored with higher accuracy).

However, the blood flow measurement unit 12 may have any configuration as long as the blood flow BF can be measured by any method. Hereinafter, for convenience of description, the description will be given by taking the case where the blood flow measuring unit 12 is a laser Doppler blood flow meter as an example.

  The blood flow measurement unit 12 includes a laser element 121, a light receiving element 122, an amplifier 123, an analog / digital (A / D) converter 124, and an arithmetic circuit 125.

  The laser element 121 irradiates a living body with laser light. At this time, the laser element 121 preferably irradiates a blood vessel in the living body with laser light. In particular, the laser element 121 preferably irradiates a blood vessel of the earlobe with laser light. However, the laser element 121 may irradiate the result of the other part with laser light.

  The light receiving element 122 receives the beat signal light generated by the mutual interference between the reflected light of the laser light from the living body and the scattered light of the laser light LB from the living body. The light receiving element 12 generates a detection current obtained by converting the received beat signal light into an electrical signal.

  The amplifier 123 amplifies the detection current output from the light receiving element 122 after converting it into a voltage signal.

  The A / D converter 124 performs A / D conversion processing (that is, quantization processing) on the output of the amplifier 123 (that is, the voltage signal corresponding to the beat signal light received by the light receiving element 122). As a result, the A / D converter 124 outputs the sample value of the voltage signal (that is, the quantized voltage signal) corresponding to the beat signal light received by the light receiving element 122 to the arithmetic circuit 125.

  The arithmetic circuit 125 performs frequency analysis using FFT (Fast Fourier Transform) on the output of the A / D converter 124 (that is, the sample value of the voltage signal corresponding to the beat signal light received by the light receiving element 122). . As a result, the arithmetic circuit 125 calculates the blood flow BF.

  In addition, the arithmetic circuit 125 calculates the heart rate HR of the living body and the pulse wave amplitude PA of the living body from the blood flow BF.

  The control unit 13 is a central control device (for example, CPU: Central Processing Unit) for controlling the physical condition monitoring device 1. The control unit 13 includes a blood pressure storage unit 131, a blood flow storage unit 132, and a risk level calculation unit 133 as a processing circuit physically realized therein or as a processing block logically realized therein. And an output unit 134.

  The blood pressure storage unit 131 is a memory that stores the blood pressure BP measured by the blood pressure measurement unit 11. Note that the blood pressure storage unit 131 preferably stores the blood pressure BP measured by the blood pressure measurement unit 11 within a certain period. Alternatively, the blood pressure storage unit 131 may store all blood pressures BP measured by the blood pressure measurement unit 11.

  The blood flow storage unit 132 is a memory that stores the blood flow BF measured by the blood flow measurement unit 12. The blood flow storage unit 132 preferably stores the blood flow BF measured by the blood flow measurement unit 12 within a certain period. Alternatively, the blood flow storage unit 132 may store all blood flows BF measured by the blood flow measurement unit 12.

  In addition, the blood flow storage unit 132 may store the heart rate HR calculated by the blood flow measurement unit 12. The blood flow storage unit 132 preferably stores the heart rate HR calculated by the blood flow measurement unit 12 within a certain period. Alternatively, the blood flow storage unit 132 may store all the heart rate HR calculated by the blood flow measurement unit 12.

  In addition, the blood flow storage unit 132 may store the pulse wave amplitude PA calculated by the blood flow measurement unit 12. Note that the blood flow storage unit 132 preferably stores the pulse wave amplitude PA calculated by the blood flow measurement unit 12 within a certain period. Alternatively, the blood flow storage unit 132 may store all the pulse wave amplitudes PA calculated by the blood flow measurement unit 12.

  The blood pressure storage unit 131 may be physically independent of the blood flow storage unit 132. Alternatively, the blood pressure storage unit 131 and the blood flow storage unit 132 may be configured from a single memory.

  In the risk level calculation unit 133, the blood pressure BP stored in the blood pressure storage unit 131, the blood flow BF stored in the blood flow storage unit 132, the heart rate HR and the pulse wave amplitude PA, and the input unit 14 receive input. Based on the calculation parameters, a physical condition risk level indicating whether or not the physical condition of the living body is good (or indicating the state of the physical condition of the living body) is calculated.

  The output unit 134 outputs the physical condition risk level calculated by the risk level calculation unit 133 to the display unit 15. As a result, the display unit 15 may display a physical condition risk level. Alternatively, the output unit 134 may output the physical condition risk level calculated by the risk level calculation unit 133 to an external device of the physical condition management device 1.

  The input unit 14 inputs calculation parameters input from the outside of the physical condition monitoring apparatus 1 by a user of the physical condition monitoring apparatus 1 (for example, a living body subject to physical condition monitoring, an operator or an administrator of the physical condition monitoring apparatus 1). Accept. The calculation parameter is an index that is referred to when the risk level calculation unit 133 calculates the physical condition risk level. In particular, the calculation parameter is an index input by the user from the outside of the physical condition monitoring device 1, unlike the measurement value (or calculated value calculated) measured by the blood pressure measurement unit 11 or the blood flow measurement unit 12. .

  Details of the calculation parameters will be described later.

  The display unit 15 displays a desired display screen. For example, the display unit 15 may display a display screen (for example, see FIG. 9 described later) indicating the physical condition risk level calculated by the risk level calculation unit 133. Alternatively, the display unit 15 may display a display screen (for example, see FIGS. 8 and 9 described later) for prompting the user to input calculation parameters. In addition, the display unit 15 may display an alarm when the physical condition risk level exceeds the allowable range.

(1-2) Operation of Physical Condition Monitoring Device Next, the flow of operation of the physical condition monitoring device 1 of the first embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing an operation flow of the physical condition monitoring apparatus 1 according to the first embodiment.

  As shown in FIG. 2, the blood flow measurement unit 12 measures the blood flow BF of the living body (step S10). The measurement of the blood flow BF of the living body by the blood flow measuring unit 12 is continuously performed until the monitoring operation of the physical condition of the living body by the physical condition monitoring device 1 is completed (step S19).

  Specifically, first, the laser element 121 irradiates a living body with laser light.

  Thereafter, the light receiving element 122 has a mutual interference of scattered light of laser light from the living body (more specifically, scattered light scattered by blood cells that are moving scatterers and tissue that is stationary (for example, skin tissue). The beat signal light generated by the mutual interference with the scattered light scattered by the light is received. Specifically, when a living body is irradiated with laser light, scattered light is generated due to the flow of blood inside blood vessels in the living body (that is, movement of red blood cells that are scatterers). The frequency of the scattered light is changed by the laser Doppler action corresponding to the moving speed of the blood as compared with the frequency of the original laser light. The light receiving element 122 receives beat signal light (so-called frequency difference signal) generated by the mutual interference of scattered light. Note that as the scattered light that generates the beat signal light, forward scattered light corresponding to the transmitted light of the laser light irradiated on the living body may be used, or backward corresponding to the reflected light of the laser light irradiated on the living body. Scattered light may be used.

  Thereafter, the light receiving element 122 generates a detection current obtained by converting the received beat signal light into an electrical signal. The light receiving element 122 outputs the generated detection current to the amplifier 123. The amplifier 123 amplifies the detection current output from the light receiving element 122 (that is, the detection current corresponding to the beat signal light received by the light receiving element 122) after converting it into a voltage signal. The amplifier outputs a voltage signal to the A / D converter 124.

  Thereafter, the A / D converter 124 performs A / D conversion processing (that is, quantization processing) on the output of the amplifier 123 (that is, the voltage signal corresponding to the beat signal light received by the light receiving element 122). As a result, the A / D converter 124 outputs the sample value of the voltage signal (that is, the quantized voltage signal) corresponding to the beat signal light received by the light receiving element 122 to the arithmetic circuit 125. Specifically, for example, when the sampling period of the A / D converter 124 is Ta, the A / D converter 124 samples the voltage signal sample value (corresponding to the beat signal light received by the light receiving element 122 for each period Ta ( That is, a quantized voltage signal) is output.

  Thereafter, the arithmetic circuit 125 performs frequency analysis using FFT (Fast Fourier Transform) on the output of the A / D converter 124 (that is, the sample value of the voltage signal corresponding to the beat signal light received by the light receiving element 12). I do. As a result, the arithmetic circuit 125 calculates the blood flow BF. Specifically, for example, the arithmetic circuit 125 performs FFT on the sample value of the voltage signal corresponding to the beat signal light. The arithmetic circuit 125 calculates the blood flow BF using a first moment that is a result of multiplying the power spectrum and the frequency vector obtained by performing the FFT. In addition, about the calculation method of the blood flow rate BF by the frequency analysis using FFT, since a well-known method (For example, the method etc. which were disclosed by patent 3313841) may be used, detailed description is abbreviate | omitted. . The arithmetic circuit 125 outputs the calculated blood flow BF to the control unit 13 (particularly, the blood flow storage unit 132). As a result, the blood flow storage unit 132 stores the blood flow BF measured by the blood flow measurement unit 12 (step S10).

  In addition to the measurement of the blood flow BF, the blood flow measurement unit 12 (in particular, the arithmetic circuit 125 included in the blood flow measurement unit 12) further determines the heart rate HR and the pulse wave amplitude from the blood flow BF measured in step S10. PA is calculated (step S11). Thereafter, the arithmetic circuit 125 outputs the calculated heart rate HR and pulse wave amplitude PA to the control unit 13 (particularly, the blood flow storage unit 132). As a result, the blood flow storage unit 132 stores the heart rate HR and the pulse wave amplitude PA calculated by the blood flow measurement unit 12 (step S11).

  Here, the heart rate HR and the pulse wave amplitude PA will be described with reference to FIG. FIG. 3 is a waveform diagram showing the relationship between heart rate HR and pulse wave amplitude PA and blood flow BF.

  As shown in FIG. 3, in the blood flow waveform obtained when the blood flow measurement unit 12 measures the blood flow BF, the frequency of the waveform corresponding to the pulse wave (that is, the reciprocal of the period A of the blood flow waveform (1 / A)) corresponds to the heart rate HR. In addition, in the blood flow waveform obtained when the blood flow measurement unit 12 measures the blood flow BF, the amplitude C of the waveform corresponding to the pulse wave corresponds to the pulse wave amplitude PA.

  In FIG. 2 again, the blood pressure measurement unit 11 measures the blood pressure BP of the living body following the measurement of the blood flow rate BF in step S10, before or after or in parallel (step S12). Thereafter, the blood pressure BP measured by the blood pressure measurement unit 11 is output to the control unit 13 (particularly, the blood pressure storage unit 131). As a result, the blood pressure storage unit 131 stores the blood pressure BP measured by the blood pressure measurement unit 11 (step S12). The measurement of the blood pressure BP of the living body by the blood pressure measurement unit 11 is continuously performed until the monitoring operation of the physical condition of the living body by the physical condition monitoring device 1 is completed (step S19).

  The blood pressure measurement unit 11 may measure the blood pressure BP at regular time intervals (for example, every 20 minutes). For example, when the measurer operates the blood pressure measurement unit 11 at regular intervals (for example, the cuff is wound around the arm of the living body and the arm of the living body is pressed through the cuff), the blood pressure BP at regular intervals. Is measured.

  Here, the cycle in which the blood pressure measurement unit 11 measures the blood pressure BP may be longer than the cycle in which the blood flow measurement unit 12 measures the blood flow BF. For example, the blood pressure measurement unit 11 measures the blood pressure BP every 20 minutes, while the blood flow measurement unit 12 measures the blood every cycle shorter than 20 minutes (for example, every several tens of milliseconds to several tens of seconds). The flow rate BF may be measured. In the case where the blood pressure measurement unit 11 is a non-invasive blood pressure monitor and the blood flow measurement unit 12 is a laser Doppler blood flow meter, the blood pressure measurement unit 11 has a blood pressure due to the labor involved in measuring the blood pressure BP. The cycle for measuring BP is often longer than the cycle for measuring blood flow BF by blood flow measurement unit 12.

  Following the measurement of blood flow BF in step S11 and the measurement of blood pressure BP in step S12, the risk level calculation unit 133 indicates whether or not the physical condition of the living body is good. The physical condition risk level (or the condition of the physical condition of the living body) is calculated (from step S14 to step S18). The calculation of the physical condition risk level by the risk level calculation unit 133 is continuously performed until the monitoring operation of the physical condition of the living body by the physical condition monitoring device 1 is completed (step S19).

  Specifically, the risk level calculation unit 133 first calculates a blood pressure risk level based on the blood pressure BP stored in the blood pressure storage unit 131 (step S14). The blood pressure risk level is an index indicating the state of the physical condition of the living body and is an index corresponding to the value of the blood pressure BP.

  Here, with reference to FIG. 4, an example of a mode of calculating the blood pressure risk level will be described. FIG. 4 is a table showing a correspondence relationship between the blood pressure risk level and the blood pressure BP.

  As illustrated in FIG. 4, the risk level calculation unit 133 may calculate the blood pressure risk level by referring to a table indicating a correspondence relationship between the blood pressure BP and the blood pressure risk level, for example. Specifically, the risk level calculation unit 133 calculates a numerical value “1” as the blood pressure risk level when the blood pressure BP is greater than 160 mmHg and equal to or less than 180 mmHg. Similarly, the risk level calculation unit 133 calculates a numerical value “2” as the blood pressure risk level when the blood pressure BP is greater than 180 mmHg. Similarly, when the blood pressure BP is greater than 140 mmHg and less than or equal to 160 mmHg, the risk level calculation unit 133 calculates a numerical value “3” as the blood pressure risk level. Similarly, the risk level calculation unit 133 calculates a numerical value “4” as the blood pressure risk level when the blood pressure BP is greater than 120 mmHg and equal to or less than 140 mmHg. Similarly, the risk level calculation unit 133 calculates a numerical value “5” as the blood pressure risk level when the blood pressure BP is greater than 100 mmHg and equal to or less than 120 mmHg. Similarly, the risk level calculation unit 133 calculates a numerical value “6” as the blood pressure risk level when the blood pressure BP is 100 mmHg or less.

  In addition, the blood pressure risk level shown in FIG. 4 indicates that the physical condition of the living body deteriorates as the numerical value increases (in other words, is not good). This is because the blood pressure risk level shown in FIG. 4 is mainly for blood pressure BP when the living body is performing artificial dialysis. When a living body is performing artificial dialysis, a decrease in blood pressure BP often indicates deterioration in physical condition (that is, deterioration in state). Therefore, the blood pressure risk level shown in FIG. 4 increases as the blood pressure BP decreases (that is, the physical condition of the living body during artificial dialysis deteriorates).

  However, the blood pressure risk level may indicate that the physical condition of the living body deteriorates as the numerical value decreases (in other words, is not good). Alternatively, the blood pressure risk level may indicate the physical condition of the living body in another manner. That is, an arbitrary index having some correspondence with the blood pressure BP and having some correspondence with the physical condition of the living body may be used as the blood pressure risk level.

  In addition to or instead of the table indicating the correspondence relationship between the blood pressure BP and the blood pressure risk level, the risk level calculation unit 133 is arbitrary information indicating the correspondence relationship between the blood pressure BP and the blood pressure risk level (for example, The blood pressure risk level may be calculated by referring to a map, a mathematical formula, a function, or the like.

  In addition, the risk level calculation unit 133 determines whether the proportional value of the blood pressure BP (for example, the value of the blood pressure BP itself or the value K × BP obtained by multiplying the blood pressure BP by a predetermined coefficient K) and the blood pressure risk level. The blood pressure risk level may be calculated by referring to arbitrary information indicating the correspondence. Alternatively, the risk level calculation unit 133 changes the blood pressure BP change rate (for example, the current blood pressure BP change rate based on a predetermined reference value (for example, the blood pressure BP before a predetermined time (for example, 10 minutes)) ΔBP The blood pressure risk level may be calculated by referring to arbitrary information indicating the correspondence between the blood pressure risk level and the blood pressure risk level. Alternatively, the risk level calculation unit 133 may be arbitrary information indicating a change mode of the blood pressure BP (for example, a current blood pressure BP change amount based on a predetermined reference value or a current amount based on a predetermined reference value). The relationship between the ratio of blood pressure BP, the amount or rate of change of blood pressure BP per predetermined time, the n of blood pressure BP (where n is an integer equal to or greater than 1), etc.) and the blood pressure risk level The blood pressure risk level may be calculated by referring to arbitrary information shown.

  Further, a plurality of tables showing the correspondence relationship between the blood pressure risk level and the blood pressure BP shown in FIG. 4 may be prepared. In this case, the risk level calculation unit 133 calculates the blood pressure risk level using a desired one of the plurality of tables. A table indicating a correspondence relationship between a blood flow risk level and a blood flow BF described later, a table indicating a correspondence relationship between a heart rate risk level and a heart rate HR described later, and a pulse wave risk level and a pulse wave described later. The same applies to the table indicating the correspondence relationship with the amplitude PA.

  In FIG. 2 again, subsequently, the risk level calculation unit 133 calculates the blood flow risk level based on the blood flow BF stored in the blood flow storage unit 132 (step S15). The blood flow risk level is an index indicating the state of the physical condition of the living body and is an index corresponding to the value of the blood flow BF.

  Here, with reference to FIG. 5, an example of a mode of calculating the blood flow risk level will be described. FIG. 5 is a table showing the correspondence between the blood flow risk level and the blood flow BF.

  As illustrated in FIG. 5, the risk level calculation unit 133 starts a calculation operation of, for example, a blood flow BF before a predetermined reference value (for example, a predetermined time (for example, 10 minutes) or the physical condition risk level illustrated in FIG. 2. By referring to a table showing the correspondence between the change rate ΔBF of the current blood flow rate BF and the blood flow risk level based on the blood flow rate BF at a predetermined time (for example, 10 minutes) A blood flow risk level may be calculated.

  Specifically, the risk level calculation unit 133 determines that the change rate ΔBF of the blood flow BF is −5% or more (that is, 0.95 × predetermined reference value ≦ current blood flow BF). The numerical value “1” is calculated as the blood flow risk level. Similarly, the risk level calculation unit 133 has a change rate ΔBF of the blood flow BF of −10% or more and less than −5% (that is, 0.90 × predetermined reference value ≦ current blood flow BF <0). .95 × predetermined reference value), a numerical value “2” is calculated as the blood flow risk level. Similarly, the risk level calculation unit 133 has a change rate ΔBF of the blood flow BF that is −20% or more and less than −10% (that is, 0.80 × predetermined reference value ≦ current blood flow BF <0). .90 × predetermined reference value), a numerical value “3” is calculated as the blood flow risk level. Similarly, the risk level calculation unit 133 has a change rate ΔBF of the blood flow BF of −30% or more and less than −20% (that is, 0.70 × predetermined reference value ≦ current blood flow BF <0). .80 × predetermined reference value), a numerical value “4” is calculated as the blood flow risk level. Similarly, the risk level calculation unit 133 has a change rate ΔBF of the blood flow BF that is −40% or more and less than −30% (that is, 0.60 × predetermined reference value ≦ current blood flow BF <0). .70 × predetermined reference value), a numerical value “5” is calculated as the blood flow risk level. Similarly, when the rate of change ΔBF of the blood flow BF is less than −40% (that is, the current blood flow BF <0.60 × predetermined reference value), the risk level calculation unit 133 sets “6 Is calculated as a blood flow risk level.

  In addition, the blood flow risk level shown in FIG. 5 indicates that the physical condition of the living body deteriorates as the numerical value increases (in other words, is not good). This is because the blood flow risk level shown in FIG. 5 mainly targets the blood flow BF when the living body is performing artificial dialysis. When the living body is performing artificial dialysis, a rapid decrease in the blood flow BF often indicates deterioration of physical condition (that is, deterioration of the state). Therefore, the blood flow risk level shown in FIG. 5 is such that the rate of change ΔBF of the blood flow BF decreases (that is, the blood flow BF decreases rapidly, in other words, the physical condition of the living body during artificial dialysis deteriorates). The numbers are increasing.

  However, the blood flow risk level may indicate that the physical condition of the living body deteriorates as the numerical value decreases (in other words, is not good). Alternatively, the blood flow risk level may indicate the physical condition of the living body in another manner. That is, an arbitrary index having some correspondence with the change rate ΔBF of the blood flow BF and having any correspondence with the physical condition of the living body is used as the blood flow risk level. Also good.

  In addition to or instead of the table indicating the correspondence relationship between the change rate ΔBF of the blood flow BF and the blood flow risk level, the risk level calculation unit 133 calculates the change rate ΔBF of the blood flow BF and the blood flow risk level. The blood flow risk level may be calculated by referring to arbitrary information (for example, a map, a mathematical expression, a function, etc.) indicating the correspondence relationship between the two.

  The risk level calculation unit 133 also calculates a proportional value of the blood flow BF (for example, the value of the blood flow BF itself or a value K × BF obtained by multiplying the blood flow BF by a predetermined coefficient K) and the blood flow risk level. The blood flow risk level may be calculated by referring to arbitrary information indicating the correspondence between the blood flow and the blood flow. Alternatively, the risk level calculation unit 133 may be arbitrary information indicating a change mode of the blood flow BF (for example, a change in the current blood flow BF with reference to a predetermined reference value or a predetermined reference value as a reference). Arbitrary information indicating a correspondence relationship between a current blood flow rate BF ratio, a change amount or change rate of the blood flow rate BF per predetermined time, an n-th order differential value of the blood flow rate BF, and the blood flow risk level. The blood flow risk level may be calculated by referring to.

  In addition, when the blood flow BF before a predetermined time is used as a reference value for calculating the change rate ΔBF of the blood flow BF, the predetermined time may be changed for each living body. For example, when there is a request to monitor the change state of the blood flow BF during a relatively short period, a relatively short time (for example, 1 minute or 10 minutes) may be set as the predetermined time. preferable. Alternatively, when there is a request to monitor the state of change in blood flow BF over a relatively long period, a relatively long time (for example, 5 minutes or 15 minutes) may be set as the predetermined time. preferable. Alternatively, as the predetermined time, an appropriate value that can remove the body movement and electrical noise of the living body may be set based on the average value of the blood flow BF. Alternatively, the blood flow rate BF measured by the blood flow measurement unit 12 at the time when the blood pressure measurement unit 11 measures the blood pressure BP may be used as the reference value when calculating the change rate ΔBF of the blood flow rate BF. The same applies to the calculation of the change rate ΔBP of the blood pressure BP, the change rate ΔHR of the heart rate HR described later, and the change rate ΔPA of the pulse wave amplitude PA described later.

  Note that, as described above, a plurality of tables indicating the correspondence between the blood flow risk level and the blood flow BF may be prepared. At this time, as shown in FIG. 5, when a table indicating the correspondence relationship between the blood flow risk level and the “change rate ΔBF” of the blood flow BF is used, a plurality of tables corresponding to a plurality of reference values are used. May be prepared. For example, (i) a table indicating a correspondence relationship between a change rate ΔBF1 of the current blood flow rate BF with reference to the blood flow rate BF before a predetermined time (for example, 10 minutes) and the blood flow risk level; Between the change rate ΔBF2 of the current blood flow rate BF with reference to the blood flow rate BF at the time when a predetermined time (for example, 10 minutes) has elapsed since the calculation of the physical condition risk level shown in FIG. And a table indicating the correspondence relationship may be prepared. The same applies to “the rate of change ΔHR of the heart rate HR” described later, “the rate of change ΔPA of the pulse wave amplitude PA” described later, and “the rate of change ΔBP of the blood pressure BP” described above.

  In FIG. 2 again, subsequently, the risk level calculation unit 133 calculates a heart rate risk level based on the heart rate HR stored in the blood flow storage unit 132 (step S16). The heart rate risk level is an index indicating the state of the physical condition of the living body and is an index corresponding to the value of the heart rate HR.

  Here, with reference to FIG. 6, an example of a mode of calculating the heart rate risk level will be described. FIG. 6 is a table showing the correspondence between the heart rate risk level and the heart rate HR.

  As shown in FIG. 6, the risk level calculation unit 133 starts a calculation operation of, for example, a predetermined reference value (for example, a heart rate HR before a predetermined time (for example, 10 minutes) or a physical condition risk level shown in FIG. By referring to a table showing a correspondence relationship between a rate of change ΔHR of the current heart rate HR and a heart rate risk level based on a heart rate HR at a predetermined time (for example, 10 minutes). A risk level may be calculated.

  Specifically, the risk level calculation unit 133 has an absolute value of the rate of change ΔHR of the heart rate HR of 5% or less (that is, | 0.95 × predetermined reference value | ≦ | current heart rate HR | In this case, the numerical value “1” is calculated as the heart rate risk level. Similarly, the risk level calculation unit 133 has an absolute value of the rate of change ΔHR of the heart rate HR greater than 5% and less than or equal to 10% (that is, | 0.90 × predetermined reference value | ≦ | current heart rate) HR | <| 0.95 × predetermined reference value |), the numerical value “2” is calculated as the heart rate risk level. Similarly, the risk level calculation unit 133 has an absolute value of the rate of change ΔHR of the heart rate HR greater than 10% and 20% or less (that is, | 0.80 × predetermined reference value | ≦ | current heart rate). HR | <| 0.90 × predetermined reference value |), the numerical value “3” is calculated as the heart rate risk level. Similarly, the risk level calculation unit 133 has an absolute value of the rate of change ΔHR of the heart rate HR greater than 20% and less than 30% (that is, | 0.70 × predetermined reference value | ≦ | current heart rate). HR | <| 0.80 × predetermined reference value |), a numerical value “4” is calculated as the heart rate risk level. Similarly, the risk level calculation unit 133 has an absolute value of the rate of change ΔHR of the heart rate HR greater than 30% and less than or equal to 40% (that is, | 0.60 × predetermined reference value | ≦ | current heart rate HR | <| 0.70 × predetermined reference value |), the numerical value “5” is calculated as the heart rate risk level. Similarly, the risk level calculation unit 133 makes the absolute value of the rate of change ΔHR of the heart rate HR greater than 40% (that is, | present heart rate HR | <| 0.60 × predetermined reference value |). In this case, a numerical value “6” is calculated as the heartbeat risk level.

  The heart rate risk level shown in FIG. 6 indicates that the physical condition of the living body deteriorates as the value increases (in other words, it is not good). This is because the heart rate risk level shown in FIG. 6 is mainly for the heart rate HR when the living body is performing artificial dialysis. When the living body is performing artificial dialysis, a rapid change in the heart rate HR often indicates deterioration of physical condition (that is, deterioration of state). Therefore, the heart rate risk level shown in FIG. 6 increases the absolute value of the rate of change ΔHR of the heart rate HR (that is, the heart rate HR changes rapidly, in other words, the physical condition of the living body during artificial dialysis deteriorates). The numbers are getting bigger.

  However, the heart rate risk level may indicate that the physical condition of the living body deteriorates as the numerical value decreases (in other words, is not good). Alternatively, the heart rate risk level may indicate the physical condition of the living body in another manner. That is, any index that has some correspondence with the rate of change ΔHR of the heart rate HR and has some correspondence with the physical condition of the living body may be used as the heart rate risk level.

  In addition to or instead of the table indicating the correspondence between the rate of change ΔHR of the heart rate HR and the heart rate risk level, the risk level calculation unit 133 may determine whether the rate of change ΔHR of the heart rate HR is equal to the heart rate risk level. The blood flow risk level may be calculated by referring to arbitrary information (for example, a map, a mathematical expression, a function, or the like) indicating the correspondence relationship.

  The risk level calculation unit 133 also calculates a proportional value of the heart rate HR (for example, a value of the heart rate HR itself or a value K × HR obtained by multiplying the heart rate HR by a predetermined coefficient K) and a heart rate risk level. The heart rate risk level may be calculated by referring to arbitrary information indicating the correspondence between the two. Alternatively, the risk level calculation unit 133 may be arbitrary information indicating a change mode of the heart rate HR (for example, a change amount of the current heart rate HR based on a predetermined reference value or a predetermined reference value as a reference). Arbitrary information indicating the correspondence between the current heart rate HR ratio, the amount or rate of change of the heart rate HR per predetermined time, the nth derivative of the heart rate HR, and the heart rate risk level The heart rate risk level may be calculated by referring to it.

  In FIG. 2 again, subsequently, the risk level calculation unit 133 calculates a pulse wave risk level based on the pulse wave amplitude PA stored in the blood flow storage unit 132 (step S17). The pulse wave risk level is an index indicating the state of the physical condition of the living body and is an index corresponding to the value of the pulse wave amplitude PA.

  Here, with reference to FIG. 7, an example of a mode of calculating the pulse wave risk level will be described. FIG. 7 is a table showing the correspondence between the pulse wave risk level and the pulse wave amplitude PA.

  As shown in FIG. 7, the risk level calculation unit 133 starts a calculation operation of, for example, a predetermined reference value (for example, the pulse wave amplitude PA before a predetermined time (for example, 10 minutes) or the physical condition risk level shown in FIG. A table showing a correspondence relationship between a change rate ΔPA of the current pulse wave amplitude PA and a pulse wave risk level with reference to a pulse wave amplitude PA at a predetermined time (for example, 10 minutes) has been referenced. Thus, the pulse wave risk level may be calculated.

  Specifically, the risk level calculation unit 133 determines that the rate of change ΔPA of the pulse wave amplitude PA is −5% or more (that is, 0.95 × predetermined reference value ≦ current pulse wave amplitude). , “1” is calculated as the pulse wave risk level. Similarly, the risk level calculation unit 133 has a change rate ΔPA of the pulse wave amplitude PA of −10% or more and less than −5% (that is, 0.90 × predetermined reference value ≦ current pulse wave amplitude PA). <0.95 × predetermined reference value), a value of “2” is calculated as the blood flow risk level. Similarly, the risk level calculation unit 133 has a change rate ΔPA of the pulse wave amplitude PA of −20% or more and less than −10% (that is, 0.80 × predetermined reference value ≦ current pulse wave amplitude PA). <0.90 × predetermined reference value), a numerical value “3” is calculated as the blood flow risk level. Similarly, the risk level calculation unit 133 has a change rate ΔPA of the pulse wave amplitude PA of −30% or more and less than −20% (that is, 0.70 × predetermined reference value ≦ current pulse wave amplitude PA). <0.80 × predetermined reference value), a numerical value “4” is calculated as the blood flow risk level. Similarly, the risk level calculation unit 133 has a change rate ΔPA of the pulse wave amplitude PA of −40% or more and less than −30% (that is, 0.60 × predetermined reference value ≦ current pulse wave amplitude PA). <0.70 × predetermined reference value), a numerical value “5” is calculated as the blood flow risk level. Similarly, when the change rate ΔPA of the pulse wave amplitude PA is less than −40% (that is, the current pulse wave amplitude PA <0.60 × predetermined reference value), the risk level calculation unit 133 The numerical value “6” is calculated as the blood flow risk level.

  The pulse wave risk level shown in FIG. 7 indicates that the physical condition of the living body deteriorates as the numerical value increases (in other words, is not good). This is because the pulse wave risk level shown in FIG. 7 mainly targets the pulse wave amplitude PA when the living body is performing artificial dialysis. When the living body is performing artificial dialysis, a rapid decrease in the pulse wave amplitude PA often indicates deterioration of physical condition (that is, deterioration of state). Therefore, the pulse wave risk level shown in FIG. 7 decreases the rate of change ΔPA of the pulse wave amplitude PA (that is, the pulse wave amplitude PA decreases rapidly, in other words, the physical condition of the living body during artificial dialysis deteriorates). The numbers are getting bigger.

  However, the pulse wave risk level may indicate that the physical condition of the living body deteriorates as the numerical value decreases (in other words, is not good). Alternatively, the pulse wave risk level may indicate the physical condition of the living body in another manner. That is, an arbitrary index having any correspondence with the change rate ΔPA of the pulse wave amplitude PA and having any correspondence with the physical condition of the living body is used as the pulse wave risk level. May be.

  In addition to or instead of the table indicating the correspondence relationship between the change rate ΔPA of the pulse wave amplitude PA and the pulse wave risk level, the risk level calculation unit 133 changes the change rate ΔPA of the pulse wave amplitude PA and the pulse wave risk. The pulse wave risk level may be calculated by referring to arbitrary information (for example, a map, a mathematical expression, a function, etc.) indicating a correspondence relationship between the levels.

  The risk level calculation unit 133 also calculates a proportional value of the pulse wave amplitude PA (for example, a value of the pulse wave amplitude PA itself or a value K × PA obtained by multiplying the pulse wave amplitude PA by a predetermined coefficient K) and the pulse wave amplitude PA. The pulse wave risk level may be calculated by referring to arbitrary information indicating the correspondence relationship between the wave risk level. Alternatively, the risk level calculation unit 133 may use arbitrary information indicating a change mode of the pulse wave amplitude PA (for example, a change amount of the current pulse wave amplitude PA based on a predetermined reference value or a predetermined reference value as a reference). The ratio between the current pulse wave amplitude PA, the amount or rate of change of the pulse wave amplitude PA per predetermined time, the nth-order differential value of the pulse wave amplitude PA, etc.) Correspondence between ΔPA and pulse wave risk level The pulse wave risk level may be calculated by referring to arbitrary information indicating the relationship.

  In FIG. 2 again, subsequently, the risk level calculation unit 133 performs the blood pressure risk level calculated in step S14, the blood flow risk level calculated in step S15, the heart rate risk level calculated in step S16, and the pulse wave calculated in step S17. Based on the risk level, a physical condition risk level indicating whether or not the physical condition of the living body is good (or indicating the state of the physical condition of the living body) is calculated (step S18). In particular, in the first embodiment, the risk level calculation unit 133 is based not only on the blood pressure risk level, the blood flow risk level, the heart rate risk level, and the pulse wave risk level, but also on the calculation parameters received by the input unit 14. Calculate physical condition risk level.

  For this reason, in 1st Example, the input part 14 of the physical condition monitoring apparatus 1 is measured following the measurement of the blood flow BF in step S11, and the measurement of the blood pressure BP in step S12. An input of calculation parameters input from the outside by the user of the physical condition monitoring device 1 is received (step S13). At this time, it is preferable that the input unit 15 accepts the input of calculation parameters in a manner that can be distinguished for each living body (that is, for each individual).

  At this time, the input unit 14 controls the display unit 15 to display a display screen for prompting the user to input a calculation parameter (hereinafter, referred to as “parameter input screen” as appropriate), and displays the parameter input screen. An input of calculation parameters may be accepted via

  Here, the parameter input screen will be described with reference to FIGS. 8 and 9 are plan views showing an example of the parameter input screen.

  As shown in FIG. 8, the parameter input screen displayed on the display unit 15 is for accepting an input of a weighting coefficient BPw indicating a weighting (in other words, a contribution) of a blood pressure risk level when calculating a physical condition risk level. GUI 202 for receiving input of GUI (Graphic User Interface) 201, weighting coefficient ΔBFw indicating weighting of blood flow risk level when calculating physical condition risk level, and weighting of heart rate risk level when calculating physical condition risk level And a GUI 204 for receiving an input of a weighting coefficient ΔPAw indicating weighting of a pulse wave risk level when calculating a physical condition risk level. In FIG. 8, a numerical value “2” is input as the weighting coefficient BPw, a numerical value “1” is input as the weighting coefficient ΔBFw, a numerical value “1” is input as the weighting coefficient ΔHRw, and “0” is input as the weighting coefficient ΔPAw. An example is shown in which a numerical value is input.

  In the first embodiment, the blood pressure risk level is calculated from the blood pressure BP itself. Therefore, the weighting coefficient BPw indicates the weighting of the blood flow risk level calculated from the blood pressure BP itself. However, in addition to or instead of the GUI 201 that receives the input of the weighting coefficient BPw, the parameter input screen receives an input of the change rate ΔBP of the blood pressure BP or the weighting coefficient ΔBPw indicating the weighting of the blood flow risk level calculated from the change state. May be provided.

  Similarly, in the first embodiment, the blood flow risk level is calculated from the rate of change ΔBF of the blood flow BF. Therefore, the weighting coefficient ΔBFw indicates the weighting of the blood flow risk level calculated from the change rate ΔBF of the blood flow BF. However, in addition to or instead of the GUI 202 that receives the input of the weighting coefficient ΔBFw, the parameter input screen is a GUI for receiving the input of the weighting coefficient BFw indicating the weighting of the blood flow risk level calculated from the proportional value of the blood flow BF. May be provided. The same applies to the heart rate HR and the pulse wave amplitude PA.

  In addition, the parameter input screen displays the GUI 211 that receives input of the risk initial value OFS that defines the initial value of the physical condition risk level when calculating the physical condition risk level, and the sensitivity of the physical condition risk level when calculating the physical condition risk level. The GUI 212 that accepts the input of the risk sensitivity s to be defined, and the risk sensitivity s is a provisional physical risk level calculated from the blood pressure risk level, the blood flow risk level, the heart rate risk level, and the pulse wave risk level. It is an index for adjustment. The risk sensitivity s is typically an index that is multiplied with the provisional physical condition risk level. That is, while the above-described weighting coefficient BPw and the like are individually used for weighting processing for the corresponding individual risk level, the risk sensitivity s is weighting processing for the overall physical condition risk level (in other words, provisional physical condition Used for risk level adjustment).

  For example, when the physical condition of the living body has already deteriorated at the time of starting the monitoring of the physical condition by the physical condition monitoring apparatus 1, the risk initial value OFS is relatively compared with the case where the physical condition of the living body has not deteriorated. It is preferable that a large value is input. Alternatively, if there is a flaw between the calculated physical condition risk level and the actual physical condition of the living body during the period in which the physical condition monitoring by the physical condition monitoring device 1 has already been performed, the wrinkle is eliminated. Thus, the risk initial value OFS may be input. The same applies to the risk sensitivity s.

  The risk initial value OFS and the risk sensitivity s may be input in such a manner that they can be distinguished according to the elapsed time from the start of the monitoring of the physical condition of the living body by the physical condition monitoring device 1. In this case, it is preferable that the GUI 211 that receives an input of the risk initial value OFS included in the parameter input screen further includes an icon capable of inputting an elapsed time. Similarly, it is preferable that the GUI 212 that receives the input of the risk sensitivity s further includes an icon that can input an elapsed time. Note that the parameter input screen shown in FIG. 8 displays a graph 213 showing the correspondence between the elapsed time and the risk sensitivity s.

  In addition, the parameter input screen includes a GUI 221 that receives an input of a disease affected by a living body that is a physical condition monitoring target, and a GUI 222 that receives an input of a medicine taken by the living body that is a physical condition monitoring target. And a GUI 223 that receives an input as to whether or not the living body whose physical condition is to be monitored uses a cardiac pacemaker.

  In addition, the parameter input screen is used to input reference values for calculating the above-described blood pressure BP change rate ΔBP, blood flow rate BF change rate ΔBF, heart rate HR change rate ΔHR, and pulse wave amplitude PA change rate ΔPA. Is provided. In the first embodiment, the reference value is a measured value (blood pressure BP, blood flow BF, heart rate HR, and pulse wave amplitude PA) at a predetermined time. Therefore, FIG. 8 shows an example in which “reference time” is input as a reference value which is an example of a calculation parameter. Specifically, in FIG. 8, “10 minutes before the current time as a reference” and “20 minutes after the start of the calculation operation of the physical condition risk level shown in FIG. 2” are input as the reference time. An example is shown.

  In addition, as illustrated in FIG. 9, the parameter input screen displayed on the display unit 15 includes a GUI 231 and a GUI 232 that receive an input of a biological state when an alarm corresponding to the physical condition risk level is issued. For example, when an alarm indicating that the physical condition of the living body is not good is issued according to the physical condition risk level, if the actual state of the physical condition of the living body is good, the user of the physical condition monitoring device 1 is in good health The GUI 232 is selected to indicate that (in other words, as usual). As a result, information indicating that the issued alarm is not useful is input as a calculation parameter. On the other hand, for example, when an alarm indicating that the physical condition of the living body is not good is issued according to the physical condition risk level, if the actual state of the physical condition of the living body is not good, the user of the physical condition monitoring device 1 In order to indicate that the physical condition is not good (in other words, attention is required), the GUI 231 is selected. As a result, information indicating that the issued alarm is useful is input as a calculation parameter.

  The parameter input screen shown in FIG. 9 includes the current state of the physical condition risk level, the current state of the blood pressure risk level, the current state of the blood flow risk level, the current state of the heart rate risk level, The current state of the wave risk level is displayed.

  In FIG. 2 again, using the calculation parameters input in this way, the risk level calculation unit 133 calculates a physical condition risk level (step S19).

  For example, a case where the above-described weighting coefficient BPw, weighting coefficient ΔBFw, weighting coefficient ΔHRw, and weighting coefficient ΔPAw are input as calculation parameters will be described as an example. In this case, the risk level calculation unit 133 multiplies the weighting coefficient BPw and the blood pressure risk level, the weighting coefficient ΔBFw and the blood flow risk level, the weighting coefficient ΔHRw and the heart rate risk level, A value obtained by adding the weighted coefficient ΔPAw and the product of the pulse wave risk level may be calculated as the physical condition risk level. That is, the risk level calculation unit 133 uses a mathematical formula: physical condition risk level = weighting coefficient BPw × blood pressure risk level + weighting coefficient ΔBFw × blood flow risk level + weighting coefficient ΔHRw × heart rate risk level + weighting coefficient ΔPAw × pulse wave risk level. Thus, the physical condition risk level may be calculated.

  Here, specific examples of the weighting coefficient BPw, the weighting coefficient ΔBFw, the weighting coefficient ΔHRw, and the weighting coefficient ΔPAw will be described with reference to FIG. FIG. 10 is a table showing specific examples of the weighting coefficient BPw, the weighting coefficient ΔBFw, the weighting coefficient ΔHRw, and the weighting coefficient ΔPAw.

  As shown in FIG. 10, a numerical value “2” is input as the weighting coefficient BPw, a numerical value “3” is input as the weighting coefficient ΔBFw, a numerical value “1” is input as the weighting coefficient ΔHRw, and the weighting coefficient ΔPAw is input. It is assumed that a numerical value “1” is input. In this case, the risk level calculation unit 133 may calculate the physical condition risk level using a mathematical formula of physical condition risk level = 2 × blood pressure risk level + 3 × blood flow risk level + 1 × heart rate risk level + 1 × pulse wave risk level. Good.

  However, the risk level calculation unit 133 weights the multiplication value of the weighting coefficient BPw and the blood pressure risk level, the multiplication value of the weighting coefficient ΔBFw and the blood flow risk level, the multiplication value of the weighting coefficient ΔHRw and the heart rate risk level, and weighting. A value obtained by multiplying the multiplication value of the coefficient ΔPAw and the pulse wave risk level may be calculated as the physical condition risk level. That is, the risk level calculation unit 133 uses the following formula: physical condition risk level = weighting coefficient BPw × blood pressure risk level × weighting coefficient ΔBFw × blood flow risk level × weighting coefficient ΔHRw × heart rate risk level × weighting coefficient ΔPAw × pulse wave risk level. Thus, the physical condition risk level may be calculated.

  Alternatively, the risk level calculation unit 133 may calculate the physical condition risk level based on an arbitrary function having the blood pressure risk level, the blood flow risk level, the heart rate risk level, and the pulse wave risk level as variables. That is, the risk level calculation unit 133 has a physical condition risk level = f (weighting coefficient BPw × blood pressure risk level, weighting coefficient ΔBFw × blood flow risk level, weighting coefficient ΔHRw × heart rate risk level, weighting coefficient ΔPAw × pulse wave risk level). The physical condition risk level may be calculated using a function. Alternatively, the risk level calculation unit 133 uses any method from the blood pressure risk level, the blood flow risk level, the heart rate risk level, the pulse wave risk level, the weighting coefficient BPw, the weighting coefficient ΔBFw, the weighting coefficient ΔHRw, and the weighting coefficient ΔPAw. You may calculate a physical condition risk level.

  Subsequently, a case where the risk initial value OFS and the risk sensitivity s described above are input as calculation parameters will be described as an example. In this case, the risk level calculation unit 133 uses a risk initial value as a value obtained by multiplying the sum of the blood pressure risk level, the blood flow risk level, the heart rate risk level, and the pulse wave risk level by the risk sensitivity s. You may calculate a physical condition risk level by adding to OFS. That is, the risk level calculation unit 133 uses the mathematical formula: physical condition risk level = risk initial value OFS + risk sensitivity s × (blood pressure risk level + blood flow risk level + heart rate risk level + pulse wave risk level) to calculate the physical condition risk level. It may be calculated.

  When the weighting coefficient BPw, the weighting coefficient ΔBFw, the weighting coefficient ΔHRw, and the weighting coefficient ΔPAw are input as calculation parameters in addition to the risk initial value OFS and the risk sensitivity s, the risk level calculation unit 133 displays the physical condition risk level. = Risk initial value OFS + risk sensitivity s × (weighting coefficient BPw × blood pressure risk level + weighting coefficient ΔBFw × blood flow risk level + weighting coefficient ΔHRw × heart rate risk level + weighting coefficient ΔPAw × pulse wave risk level) You may calculate a physical condition risk level.

  Next, a case where information indicating a disease affected by a living body, information indicating a drug taken by the living body, and information indicating whether or not the living body uses a cardiac pacemaker will be described as calculation parameters. . In this case, the risk calculation unit 133 automatically sets at least one of the above-described weighting coefficient BPw, weighting coefficient ΔBFw, weighting coefficient ΔHRw, and weighting coefficient ΔPAw according to the input calculation parameter. Also good.

  For example, depending on the disease affected by the living body, at least one of blood pressure BP, blood flow BF, heart rate HR, and pulse wave amplitude PA cannot be measured normally, or blood pressure BP, blood flow BF, heart rate HR, and pulse wave There is a possibility that useful information included in at least one of the amplitudes PA may be relatively reduced. Therefore, the risk calculation unit 133 is relatively small as a weighting coefficient corresponding to a measurement target value that cannot be measured normally or that reduces useful information in accordance with the disease that the living body suffers from. A value (for example, a value less than 1 or 0) may be set.

  Alternatively, for example, depending on the disease that the living body suffers from, the physical condition of the living body is preferably monitored by intensively monitoring at least one of the blood pressure BP, the blood flow BF, the heart rate HR, and the pulse wave amplitude PA. There are cases where it is possible. Therefore, the risk calculation unit 133 sets a relatively large value (for example, a value of 1 or more) as the weighting coefficient corresponding to the measurement target value that is preferably monitored with priority according to the disease that the living body suffers from. It may be set.

  For example, depending on the medicine taken by the living body, at least one of blood pressure BP, blood flow BF, heart rate HR and pulse wave amplitude PA cannot be measured normally, or blood pressure BP, blood flow BF, heart rate HR and pulse There is a possibility that useful information included in at least one of the wave amplitudes PA may be relatively reduced. Therefore, according to the medicine that the living body is taking, the risk calculation unit 133 is relatively used as a weighting coefficient corresponding to the measurement target value that cannot be measured normally or the useful information is relatively reduced. A small value (for example, a value less than 1 or 0) may be set.

  Alternatively, for example, depending on the medicine taken by the living body, the physical condition of the living body is preferably monitored by intensively monitoring at least one of the blood pressure BP, the blood flow BF, the heart rate HR, and the pulse wave amplitude PA. You may be able to. Therefore, according to the medicine that the living body is taking, the risk calculation unit 133 has a relatively large value (for example, a value of 1 or more) as the weighting coefficient corresponding to the measurement target value that is preferably monitored with priority. May be set.

  Alternatively, for example, when the living body uses a cardiac pacemaker, there is a possibility that the heart rate HR cannot be measured normally or useful information included in the heart rate HR is relatively reduced. Therefore, when the living body uses a cardiac pacemaker, the risk calculation unit 133 makes the weighting coefficient ΔHRw corresponding to the heart rate HR smaller than the other weighting coefficients BPw, weighting coefficient ΔBFw, and weighting coefficient ΔPAw. The weighting coefficient ΔHRw corresponding to the heart rate HR is set. Alternatively, the risk calculation unit 133 may set “0” as the weighting coefficient ΔHRw corresponding to the heart rate HR.

  Here, referring to FIG. 11, it is set according to information indicating a disease affected by the living body, information indicating a medicine taken by the living body, and information indicating whether or not the living body uses a cardiac pacemaker. Specific examples of the weighting coefficient BPw, the weighting coefficient ΔBFw, the weighting coefficient ΔHRw, and the weighting coefficient ΔPAw will be described. FIG. 11 shows the weighting coefficient BPw set according to the information indicating the disease that the living body suffers, the information indicating the medicine that the living body is taking, and the information indicating whether or not the living body is using a cardiac pacemaker. It is a table which shows the specific example of coefficient (DELTA) BFw, weighting coefficient (DELTA) HRw, and weighting coefficient (DELTA) PAw.

  As shown in FIG. 11, when information indicating that the living body uses a cardiac pacemaker is input as a calculation parameter, the weighting coefficient BPw corresponding to the blood pressure BP, the weighting coefficient ΔBFw corresponding to the blood flow BF, and While “1” is set as the weighting coefficient ΔPAw corresponding to the pulse wave amplitude PA, “0” may be set as the weighting coefficient ΔHRw corresponding to the heartbeat HR.

  As shown in FIG. 11, when information indicating that the living body suffers from the disease A is input as a calculation parameter, “2” is set as the weighting coefficient BPw corresponding to the blood pressure BP, and the heart rate HR is set. “1” may be set as the weighting coefficient ΔPAw corresponding to the corresponding weighting coefficient ΔHRw and the pulse wave amplitude PA, and “0” may be set as the weighting coefficient ΔBFw corresponding to the blood flow BF.

  As shown in FIG. 11, when information indicating that the living body suffers from disease B is input as a calculation parameter, “1.5” is set as the weighting coefficient BPw corresponding to the blood pressure BP, and the heart rate “1” may be set as the weighting coefficient ΔHRw corresponding to HR, and “0” may be set as the weighting coefficient ΔBFw corresponding to the blood flow BF and the weighting coefficient ΔPAw corresponding to the pulse wave amplitude PA.

  As shown in FIG. 11, information indicating that the living body is taking the medicine A is set with the calculation parameter 0.3 ”, the weighting coefficient ΔBFw corresponding to the blood flow BF, and the weighting coefficient ΔHRw corresponding to the heart rate HR. Also, “1” may be set as the weighting coefficient ΔPAw corresponding to the pulse wave amplitude PA.

  As shown in FIG. 11, information indicating that the living body is taking the medicine B is set with the calculation parameter 0.8 ”, the weighting coefficient ΔBFw corresponding to the blood flow BF, and the weighting coefficient ΔHRw corresponding to the heart rate HR. Also, “1” may be set as the weighting coefficient ΔPAw corresponding to the pulse wave amplitude PA.

  Subsequently, as calculation parameters, a reference value (that is, a first value for calculating a change rate ΔBP of the blood pressure BP, a change rate ΔBF of the blood flow BF, a change rate ΔHR of the heart rate HR, and a change rate ΔPA of the pulse wave amplitude PA). In the embodiment, a case where “reference time”) is input will be described. In this case, the risk calculation unit 133 determines the change rate ΔBP of the blood pressure BP, the change rate ΔBF of the blood flow BF, the change rate ΔHR of the heart rate HR, and the pulse wave amplitude PA described above according to the input calculation parameters. The change rate ΔPA may be calculated.

  Next, a case where information indicating whether or not the issued warning is useful is input as a calculation parameter will be described. In this case, the risk calculation unit 133 may automatically set at least one of the risk initial value OFS and the risk sensitivity s described above according to the input calculation parameter. In other words, the risk calculation unit 133 appropriately updates at least one of the risk initial value OFS and the risk sensitivity s input as calculation parameters according to information indicating whether or not the issued alarm is useful. May be. Further, the risk calculation unit 133 may update at least one weight of the risk initial value OFS and the risk sensitivity s with respect to the elapsed time.

  For example, when the alarm is not useful, it is estimated that the calculated physical condition risk level is an excessively large value. Therefore, in this case, the risk level calculation unit 133 reduces the risk initial value so that at least one of the risk initial value OFS and the risk sensitivity s decreases (that is, it becomes difficult to calculate an excessively high physical condition risk level). At least one of the value OFS and the risk sensitivity s may be set.

  Alternatively, for example, when the alarm is useful, it may be preferable to relatively increase the accuracy or strength of monitoring because the physical condition of the living body is not relatively good. Therefore, in this case, the risk level calculation unit 133 increases the risk so that at least one of the initial risk value OFS and the risk sensitivity s increases (that is, a relatively large physical condition risk level is easily calculated). At least one of the initial value OFS and the risk sensitivity s may be set.

  A specific example of the set risk sensitivity s (particularly, the risk sensitivity s associated with the elapsed time) is shown in FIG.

  As described above, the physical condition monitoring apparatus 1 according to the first embodiment includes the blood pressure BP measured by the blood pressure measurement unit 11, the blood flow BF measured by the blood flow measurement unit 12, and the blood flow BF measured by the blood flow measurement unit 12. The physical condition risk level can be calculated on the basis of the heart rate HR and the pulse wave amplitude PA calculated from the above and the calculation parameters for which the input unit 14 receives input. That is, the physical condition monitoring apparatus 1 of the first embodiment calculates the physical condition risk level based only on the measurement values (that is, blood pressure BP, blood flow BF, heart rate HR, and pulse wave amplitude PA) measured by various measuring units. Instead, the physical condition risk level can be calculated based on each of the measurement value and the calculation parameter input by the user. Therefore, the physical condition monitoring apparatus 1 of the first embodiment calculates the physical condition risk level based only on the measured value (in other words, calculates the physical condition risk level without using the calculation parameter). Thus, the physical condition of the living body can be monitored more suitably (for example, with higher accuracy).

  In the above description, the risk level calculation unit 133 calculates the physical condition risk level based on the blood pressure risk level, the blood flow risk level, the heart rate risk level, the pulse wave risk level, and the calculation parameters. However, the risk level calculation unit 133 may calculate the physical condition risk level based on at least one of the blood pressure risk level, the blood flow risk level, the heart rate risk level, and the pulse wave risk level and the calculation parameter.

(2) Second Example Next, the physical condition monitoring device 2 of the second example will be described with reference to FIGS. 13 to 14. In the following description, the same reference numerals and step numbers are assigned to the same configurations and operations as those of the physical condition monitoring apparatus 1 of the first embodiment, and detailed description thereof is omitted.

(2-1) Configuration of Physical Condition Monitoring Device First, the configuration of the physical condition monitoring device 2 of the second embodiment will be described with reference to FIG. FIG. 13 is a block diagram illustrating a configuration of the physical condition monitoring apparatus 2 according to the second embodiment.

  As shown in FIG. 13, the physical condition monitoring device 2 of the second example is similar to the physical condition monitoring device 1 of the first example, in which the blood pressure measurement unit 11, the blood flow measurement unit 12, the input unit 14, and the display are displayed. Part 15.

  The physical condition monitoring device 2 according to the second embodiment further includes a control unit 23. The control unit 23 of the second embodiment is different from the control unit 13 of the first embodiment in that it further includes a measurement instruction unit 235. Other components included in the controller 23 of the second embodiment may be the same as other components included in the controller 12 of the first embodiment.

  The measurement instruction unit 235 may control the blood flow measurement unit 12 so that the blood flow measurement unit 12 measures the blood flow BF when the blood pressure BP measured by the blood pressure measurement unit 11 satisfies a predetermined condition. In other words, the measurement instruction unit 235 controls the blood flow measurement unit 12 so that the blood flow measurement unit 12 does not measure the blood flow BF when the blood pressure BP measured by the blood pressure measurement unit 11 does not satisfy the predetermined condition. May be.

  In addition to or instead of controlling the blood flow measurement unit 12, the measurement instruction unit 235 causes the risk level calculation unit 133 to calculate a physical condition risk level when the blood pressure BP measured by the blood pressure measurement unit 11 satisfies a predetermined condition. As such, the risk level calculation unit 133 may be controlled. In other words, the measurement instruction unit 235 controls the risk level calculation unit 133 so that the risk level calculation unit 133 does not calculate the physical condition risk level when the blood pressure BP measured by the blood pressure measurement unit 11 does not satisfy the predetermined condition. May be.

(2-2) Operation of Physical Condition Monitoring Device Next, the flow of operation of the physical condition monitoring device 2 of the second embodiment will be described with reference to FIG. FIG. 14 is a flowchart showing a flow of operations of the physical condition monitoring apparatus 2 according to the second embodiment.

  As shown in FIG. 14, also in the second embodiment, the blood pressure measurement unit 11 measures the blood pressure BP of the living body as in the first embodiment (step S12). Further, the blood pressure storage unit 131 stores the blood pressure BP measured by the blood pressure measurement unit 11 (step S12).

  Particularly in the second embodiment, the measurement instruction unit 235 determines whether or not the blood pressure BP measured in step S12 satisfies a predetermined condition (step S21).

  For example, the measurement instruction unit 235 is a value for which the blood pressure BP measured in step S12 requires continuous monitoring (for example, a value that is not a normal value or a value that is a normal value but requires attention). It may be determined whether or not. When the blood pressure BP measured in step S12 is a value that requires continuous monitoring, it may be determined that the blood pressure BP measured in step S12 satisfies a predetermined condition. On the other hand, when the blood pressure BP measured in step S12 is not a value that requires continuous monitoring, it may be determined that the blood pressure BP measured in step S12 does not satisfy the predetermined condition.

  Alternatively, the measurement instruction unit 235 determines whether the blood pressure BP measured in step S12 is another desired value or a predetermined value, or whether it falls within a predetermined range, thereby measuring the blood pressure measured in step S12. It may be determined that the BP satisfies a predetermined condition. For example, the measurement instruction unit 235 determines whether or not the blood pressure BP measured in step S12 is a predetermined value indicating that continuous monitoring of the physical condition of the living body is necessary (or the continuous condition of the biological condition of the living body). It may be determined that the blood pressure BP measured in step S12 satisfies the predetermined condition by determining whether or not it falls within a predetermined range indicating that monitoring is required. The blood pressure BP measured in step S12 is a predetermined value indicating that continuous monitoring of the physical condition of the living body is required (or within a predetermined range indicating that continuous monitoring of the physical condition of the living body is required. If the blood pressure BP measured in step S12 satisfies the predetermined condition, the blood pressure BP may be determined to satisfy the predetermined condition. On the other hand, the blood pressure BP measured in step S12 is not a predetermined value indicating that continuous monitoring of the physical condition of the living body is required (or a predetermined value indicating that continuous monitoring of the physical condition of the living body is required. If it does not fall within the range), it may be determined that the blood pressure BP measured in step S12 does not satisfy the predetermined condition.

  As a result of the determination in step S21, when it is determined that the blood pressure BP measured in step S12 does not satisfy the predetermined condition (step S21: No), the operations in step S12 and step S21 are repeated. That is, the blood pressure measurement unit 11 measures the blood pressure BP of the living body. The blood pressure storage unit 131 stores the blood pressure BP measured by the blood pressure measurement unit 11. The measurement instruction unit 235 determines whether or not the blood pressure BP measured in step S12 satisfies a predetermined condition.

  In addition, in this case, the measurement instruction unit 235 may control the blood flow measurement unit 12 so that the blood flow measurement unit 12 does not measure the blood flow BF. As a result, the blood flow measurement unit 12 may not measure the blood flow BF. In addition, the blood flow measurement unit 12 may not calculate the heart rate HR and the pulse wave amplitude PA. The measurement instruction unit 235 may control the risk level calculation unit 133 so that the risk level calculation unit 133 does not calculate the physical condition risk level in addition to or instead of controlling the blood flow measurement unit 12. . As a result, the risk level calculation unit 133 may not calculate the physical condition risk level. In addition to or instead of controlling at least one of the blood flow measurement unit 12 and the risk level calculation unit 133, the measurement instruction unit 235 prevents the input unit 14 from accepting input of calculation parameters. May be controlled. As a result, the input unit 14 does not have to accept input of calculation parameters.

  On the other hand, as a result of the determination in step S21, when it is determined that the blood pressure BP measured in step S12 satisfies a predetermined condition (step S21: Yes), the blood flow measurement unit 12 causes the blood flow measurement unit 12 to The blood flow measurement unit 12 may be controlled so as to measure the flow rate BF. As a result, the blood flow measurement unit 12 measures the blood flow BF (step S10). In addition, the blood flow measurement unit 12 calculates the heart rate HR and the pulse wave amplitude PA from the blood flow BF measured in step S10 (step S11). In addition to or instead of controlling the blood flow measurement unit 12, the measurement instruction unit 235 controls the risk level calculation unit 133 so that the risk level calculation unit 133 calculates a physical condition risk level. As a result, the risk level calculation unit 133 calculates a physical condition risk level (from step S14 to step S18). In addition to or instead of controlling at least one of the blood flow measurement unit 12 and the risk level calculation unit 133, the measurement instruction unit 235 sets the input unit 14 so that the input unit 14 receives input of calculation parameters. You may control. As a result, the input unit 14 receives input of calculation parameters.

  In addition, when it is determined that the blood pressure BP measured in step S12 satisfies the predetermined condition, the blood pressure measurement unit 11 preferably measures the blood pressure BP of the living body. When the blood pressure measurement unit 11 measures the blood pressure BP, the measurement instruction unit 235 preferably determines whether or not the newly measured blood pressure BP satisfies a predetermined condition.

  As described above, the physical condition monitoring device 2 of the second embodiment can suitably enjoy the same effects as the various effects that can be enjoyed by the physical condition monitoring device 1 of the first embodiment.

  In addition, the physical condition monitoring device 2 according to the second embodiment measures the blood flow BF and calculates the physical condition risk level when the blood pressure measured by the blood pressure measurement unit 11 satisfies a predetermined condition. In other words, the physical condition monitoring device 2 of the second embodiment may not perform measurement of the blood flow BF and calculation of the physical condition risk level when the blood pressure BP measured by the blood pressure measurement unit 11 does not satisfy the predetermined condition. For this reason, compared with the physical condition monitoring apparatus of the comparative example which always measures the blood flow volume BF and calculates the physical condition risk level, the power consumption of the physical condition monitoring apparatus 2 is reduced.

(3) Third Example Next, the physical condition monitoring device 3 of the third example will be described with reference to FIGS. In the following description, the same reference numerals and step numbers are assigned to the same configurations and operations as the physical condition monitoring apparatus 1 of the first embodiment to the physical condition monitoring apparatus 2 of the second embodiment, and the detailed description thereof will be given. Is omitted.

(3-1) Configuration of Physical Condition Monitoring Device First, the configuration of the physical condition monitoring device 3 of the third embodiment will be described with reference to FIG. FIG. 15 is a block diagram illustrating a configuration of the physical condition monitoring device 3 according to the third embodiment.

  As shown in FIG. 15, the physical condition monitoring device 3 of the third example is similar to the physical condition monitoring device 1 of the first example, in which the blood pressure measurement unit 11, the blood flow measurement unit 12, the input unit 14, and the display are displayed. Part 15.

  The physical condition monitoring device 3 of the third embodiment further includes a control unit 33. The control unit 33 of the third embodiment is different from the control unit 13 of the first embodiment in that a timer unit 336 is further provided. Other components included in the control unit 33 of the third embodiment may be the same as other components included in the control unit 12 of the first embodiment.

  The timer unit 336 sets the timing at which the blood pressure measurement unit 11 measures the blood pressure BP. In addition, the timer unit 336 controls the blood pressure measurement unit 11 to measure the blood pressure BP when the time when the blood pressure measurement unit 11 measures the blood pressure BP has come.

(3-2) Operation of Physical Condition Monitoring Device Next, the flow of operation of the physical condition monitoring device 4 of the third embodiment will be described with reference to FIG. FIG. 16 is a flowchart showing a flow of operations of the physical condition monitoring apparatus 3 according to the third embodiment.

  As shown in FIG. 16, the timer unit 336 sets the timing at which the blood pressure measurement unit 11 measures the blood pressure BP (step S31). For example, the timer unit 336 may set a cycle (for example, a cycle of 20 minutes) as the timing when the blood pressure measurement unit 11 measures the blood pressure BP. The timer unit 336 may set the time itself (for example, a time of 20 minutes, 40 minutes, 60 minutes,...) As the timing when the blood pressure measurement unit 11 measures the blood pressure BP.

  Thereafter, also in the third embodiment, as in the first embodiment, the blood flow measurement unit 12 measures the blood flow BF of the living body (step S10). In addition, in the third embodiment, as in the first embodiment, the blood flow measurement unit 12 measures the heart rate HR and the pulse wave amplitude PA based on the blood flow BF measured in step S10 ( Step S11). In addition, also in the third embodiment, as in the first embodiment, the input unit 14 receives an input of calculation parameters (step S13). In addition, also in the third example, as in the first example, the risk level calculation unit 133 calculates a physical condition risk level (from step S14 to step S18).

  Also in the third example, as in the first example, the blood pressure measurement unit 11 determines the blood pressure BP of the living body following or in parallel with the measurement of the blood flow BF in step S11. Measurement is performed (step S12). In addition, the blood pressure storage unit 131 stores the blood pressure BP measured by the blood pressure measurement unit 11 (step S12).

  Thereafter, in the third embodiment, the timer unit 336 determines whether or not the current timing is the timing set in step S31 (that is, the timing at which the blood pressure measurement unit 11 measures the blood pressure BP) (step S32). ). In other words, the timer unit 336 determines whether or not the timing set in step S31 (that is, the timing when the blood pressure measurement unit 11 measures the blood pressure BP) has arrived (step S32).

  As a result of the determination in step S32, when it is determined that the current timing is the timing set in step S31 (that is, the timing at which the blood pressure measurement unit 11 measures the blood pressure BP) (step S32: Yes), step S12 Is performed again. That is, the blood pressure measurement unit 11 measures the blood pressure BP of the living body (step S12). In addition, the blood pressure storage unit 131 stores the blood pressure BP measured by the blood pressure measurement unit 11 (step S12).

  On the other hand, as a result of the determination in step S32, when it is determined that the current timing is not the timing set in step S31 (that is, the timing at which the blood pressure measurement unit 11 measures the blood pressure BP) (step S32: No), The operation of step S12 may not be performed. That is, the blood pressure measurement unit 11 does not have to measure the blood pressure BP of the living body until the timing set in step S31 (that is, the timing when the blood pressure measurement unit 11 measures the blood pressure BP) comes again. In addition, the blood pressure storage unit 131 does not store the blood pressure BP measured by the blood pressure measurement unit 11 until the timing set in step S31 (that is, the timing when the blood pressure measurement unit 11 measures the blood pressure BP) comes again. Also good.

  As described above, the physical condition monitoring device 3 of the third embodiment can preferably enjoy the same effects as the various effects that the physical condition monitoring device 1 of the first embodiment can enjoy.

  In addition, the physical condition monitoring device 3 of the third embodiment can automatically measure the blood pressure BP at a desired timing by the operation of the timer unit 336. For this reason, the physical condition monitoring device 3 of the third embodiment can automatically measure the blood pressure BP without the measurer timing (or without the measurer manually performing the work).

  Note that the timer unit 336 may change the setting timing depending on whether or not the blood pressure BP measured by the blood pressure measurement unit 11 satisfies a predetermined condition. For example, the timer unit 336 measures the timing at which the blood pressure measurement unit 11 measures the blood pressure BP when the blood pressure BP3 measured by the blood pressure measurement unit 11 satisfies a predetermined condition (for example, a value that requires continuous monitoring). As an alternative, a relatively short cycle may be set. As a result, when the blood pressure BP measured by the blood pressure measurement unit 11 satisfies a predetermined condition, the blood pressure measurement unit 11 measures the blood pressure BP with a relatively high frequency. On the other hand, the timer unit 336 measures the blood pressure BP when the blood pressure BP measured by the blood pressure measurement unit 11 does not satisfy a predetermined condition (for example, a value that does not require continuous monitoring). A relatively long cycle may be set as the timing. As a result, when the blood pressure BP measured by the blood pressure measurement unit 11 does not satisfy the predetermined condition, the blood pressure measurement unit 11 measures the blood pressure BP with a relatively low frequency. Thereby, the blood pressure measurement unit 11 can measure the blood pressure BP at a suitable frequency according to whether or not the blood pressure BP is a value that requires continuous monitoring.

  In addition, you may combine suitably a part of each structure demonstrated in 1st Example-3rd Example. Even in this case, the blood flow rate detection device obtained by appropriately combining a part of the configurations described in the first to third embodiments can suitably enjoy the various effects described above.

  Further, the present invention can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification, and the physical condition monitoring apparatus and method involving such a change are also a technique of the present invention. Included in thought.
