The information device 200 is a device that acquires biological information obtained from the biological information measuring devices 1 and 2 and performs various processes described later. The information device 200 may be a stationary device such as a PC (Personal Computer), or a portable device such as a smartphone, a tablet terminal, or a server.

FIG. 3 is a diagram showing an example of the hardware configuration of the biological information measuring device 1 according to the embodiment. The information device 200 is also shown in FIG. The same may apply to the biological information measuring device 2.

The biological information measuring device 1 includes a light emitting unit 20 (an example of a first light emitting unit), a light receiving unit 30 (an example of a first light receiving unit), and a control unit 170, respectively. The light emitting unit 20 of the biological information measuring device 2 is an example of the second light emitting unit, and the light receiving unit 30 of the biological information measuring device 2 is an example of the second light receiving unit.

The light emitting unit 20 is provided in a housing (not shown) and irradiates light to the outside through a sensing window (not shown). The light emitting unit 20 is formed of, for example, two LEDs (Light-Emitting Diodes) having different wavelengths.

The light receiving unit 30 is provided in the same housing (not shown) as the light emitting unit 20, and receives light through a sensing window (not shown). The light receiving unit 30 is formed of, for example, a photodiode.

The control unit 170 includes an interface 132, a memory 134, a timer 136, a CPU (Central Processing Unit) 138, and an ADC (Analog to Digital Converter) 140.

The drive circuit 110 and the amplifier circuit 120 are electrically connected to the control unit 170. Further, the power supply 130 is electrically connected to the control unit 170. Further, the wireless communication unit 142 is electrically connected to the control unit 170. The control unit 170 drives and controls the light emitting unit 20 via the drive circuit 110, processes the light receiving signal obtained via the light receiving unit 30 and the ADC (Analog to Digital Converter) 140, and generates biometric information. The control unit 170 gives the generated biometric information to the wireless communication unit 142 via the interface 132. The wireless communication unit 142 transmits the biological information to the information device 200 via the antenna 144. Further, the wireless communication unit 142 receives a wireless signal from the information device 200 via the antenna 144. The wireless communication (data communication) via the antenna 144 may be based on, for example, Bluetooth (registered trademark). Further, in the modified example, the biometric information measuring device 1 may be electrically connected to the information device 200 by a wire such as USB (Universal Serial Bus).

FIG. 4 is an explanatory diagram of the measurement operation of the biological information measuring device 1. The same may apply to the biological information measuring device 2.

At the time of measurement, the user's finger (human body) comes into contact with the sensing window of the biological information measuring device 1. When the light emitting unit 20 emits light to the outside in this contact state, a part of the light passes through the human body toward the light receiving unit 30 side as schematically shown by the arrow R1 in FIG. Then, a part of the light that has passed through the human body is incident on the light receiving unit 30. The light receiving unit 30 generates an electric signal (light receiving signal) according to the light receiving result. The light receiving signal from the light receiving unit 30 is processed by the CPU 138.

The CPU 138 of the biological information measuring device 1 generates measured values related to pulse waves and hemoglobin (an example of the first measured value) as biological information based on the change in the amount of received light. Since the change in the amount of received light occurs in response to the change in the volume of the blood vessel, pulse wave information (volume pulse wave) can be obtained. In addition, since the change in the amount of received light occurs in response to the change in the concentration of hemoglobin in the bloodstream, it is possible to obtain a measured value related to hemoglobin. In this embodiment, as an example, the CPU 138 of the biological information measuring device 1 (an example of the first measured value generating unit) generates a measured value of pulse wave and a measured value of ΔHb which is an example of a measured value related to hemoglobin. To do. In this embodiment, as an example, ΔHb has three kinds of values, that is, the concentration of oxyhemoglobin, the concentration of deoxyhemoglobin, and the total value thereof.

When the CPU 138 of the biological information measuring device 1 generates each measured value of the pulse wave and ΔHb at the fingertip of the user, each measured value of the pulse wave and ΔHb at the fingertip is given to the information device 200. In the modified example, the generation of each measured value of the pulse wave and ΔHb at the fingertip may be realized by the information device 200. In this case, instead of the pulse wave at the fingertip and each measured value of ΔHb, the light receiving result in the light receiving unit 30 of the biological information measuring device 1 is given to the information device 200 from the biological information measuring device 1.

The measurement operation of the biological information measuring device 2 is also substantially the same. In the case of the biological information measuring device 2, the user's forehead (human body) comes into contact with the sensing window at the time of measurement. When the CPU 138 (an example of the second measured value generation unit) of the biological information measuring device 2 generates each measured value of the pulse wave and ΔHb at the user's forehead, the information device converts each measured value of the pulse wave and ΔHb at the forehead. Give to 200. In the modified example, the generation of each measured value of the pulse wave and ΔHb on the forehead may be realized by the information device 200. In this case, instead of each measured value of the pulse wave and ΔHb on the forehead, the light receiving result in the light receiving unit 30 of the biological information measuring device 2 is given to the information device 200 from the biological information measuring device 2.

In the following, for the sake of distinction, each measured value of the pulse wave and ΔHb generated by the biological information measuring device 1 is also referred to as “peripheral pulse wave and ΔHb”, and the pulse wave generated by the biological information measuring device 2 and Each measured value of ΔHb is also referred to as “head pulse wave and ΔHb”.

FIG. 6 is a functional block diagram for explaining the function of the processing device 70 of the information device 200.

The processing device 70 includes a first index value generation unit 701, a second index value generation unit 702, and a support information output unit 703. The first index value generation unit 701, the second index value generation unit 702, and the support information output unit 703 can be realized by the CPU 71 executing one or more programs in the storage unit such as the ROM 73.

The first index value generation unit 701 generates a first index value related to the blood circulation state of the user (hereinafter, also referred to as “first index value of the peripheral part”) based on the pulse wave of the peripheral part, and at the same time, The first index value (hereinafter, also referred to as “first index value of the head”) is generated based on the pulse wave of the head.

The first index value is, for example, an index value indicating the degree of good blood circulation. The first index value may be calculated from any one, two combinations, or all combinations of the pulse rate, the pulse amplitude, and the pulse interval that can be derived from the pulse wave. In this embodiment, as an example, the first index value has three stages ("none", "weak", and whether or not the pulse rate is significantly higher than 0, and whether or not the predetermined threshold Th1 is exceeded. "Yes"). Specifically, the first index value is a value representing "none" when the pulse rate is approximately 0, and is "weak" when the pulse rate is significantly higher than 0 but lower than the predetermined threshold Th1. It is a value representing ", and when the pulse rate is higher than the predetermined threshold Th1, it is a value representing" Yes ".

The second index value generation unit 702 has a second index value (hereinafter, “peripheral”) related to the balance between oxyhemoglobin and deoxyhemoglobin (hereinafter, also referred to as “blood oxygen balance”) based on ΔHb in the peripheral part. The second index value of the part (also referred to as "second index value of the head") is generated, and the second index value of the head (hereinafter, also referred to as "second index value of the head") is generated based on ΔHb of the head.

The second index value is, for example, an index value indicating the significance of the concentration of oxyhemoglobin with respect to the concentration of deoxyhemoglobin. In this example, as an example, the second index value is whether or not the concentration of oxyhemoglobin (or the total value with the concentration of deoxyhemoglobin) is significantly higher than 0, and from the concentration of oxyhemoglobin, the concentration of deoxyhemoglobin. It represents three stages (“none”, “weak”, and “yes”) of whether or not the difference obtained by subtracting the concentration (hereinafter referred to as “oxy-deoxy difference”) exceeds the predetermined threshold Th2. Specifically, the second index value is a value representing "none" when the concentration of oxyhemoglobin is approximately 0, and the oxy-deoxy difference in which the concentration of oxyhemoglobin is significantly larger than 0 is a predetermined threshold Th2. When it is smaller than, it is a value representing "weak", and when the oxy-deoxy difference is larger than the predetermined threshold Th2, it is a value representing "yes".

The support information output unit 703 outputs the peripheral pulse wave and ΔHb, and the head pulse wave and ΔHb to the display device 8. An output example of the display device 8 will be described later.

An output example of support information will be described later.

FIG. 7 is an explanatory diagram of a method of generating support information. In FIG. 7, the relationship between the first index value and the second index value of each part of the peripheral part and the head part is shown for each estimated category.

In FIG. 7, for example, the first index value of the peripheral portion and the first index value of the head are both "absent" as the blood circulation state, and the second index value of the peripheral portion and the second index value of the head are used as the blood oxygen balance. When both index values are "none", the support information output unit 703 estimates the current state of the user as "category 0". In this case, the support information output unit 703 outputs, for example, as support information, a black mark indicating that there is a high possibility of an apnea group (no life sign) to the display device 8.

In addition, the first index value of the peripheral part and the first index value of the head are both "weak" as the blood circulation state, and the second index value of the peripheral part is "weak" as the blood oxygen balance, and the head is the first. 2 When the index value is "none", the support information output unit 703 estimates the current state of the user as "category I". In this case, the support information output unit 703 outputs, for example, as support information, a red mark indicating that there is a high possibility of the highest priority treatment group (a serious condition life-threatening) to the display device 8.

In addition, the first index value of the peripheral part is "yes" as the blood circulation state, the first index value of the head is "weak", and the second index value of the peripheral part is "yes" as the blood oxygen balance. When the second index value of the head is "weak", the support information output unit 703 estimates the current state of the user as "category II". In this case, the support information output unit 703 outputs, for example, as support information, a yellow mark indicating that there is a high possibility of a standby treatment group (a state in which treatment should be performed early) to the display device 8.

In addition, the first index value of the peripheral part and the first index value of the head are both "presence" as the blood circulation state, and the second index value of the peripheral part and the second index value of the head are both as the blood oxygen balance. When "Yes", the support information output unit 703 estimates the current state of the user as "Category III". In this case, the support information output unit 703 outputs, for example, a green mark indicating that there is a high possibility of a holding group (a state in which immediate treatment or transportation is not required) as support information to the display device 8.

In FIG. 7, each color of the mark corresponds to each color of triage. As a result, it is possible to output support information that is easy for medical staff to understand. However, in the modified example, as the support information, the estimated category may be output in place of or in addition to the color of the mark, or voice other than the display may be output.

If the determination result is "YES", the process proceeds to step S1006, and in other cases, the processing of the current cycle ends.

In step S1006, the processing device 70 outputs the peripheral pulse wave and ΔHb and the head pulse wave and ΔHb as waveforms over a predetermined period up to the present time on the display device 8.

In step S1008, the processing device 70 (first index value generation unit 701) has the first index value of the peripheral portion and the first index value of the head based on the pulse wave and ΔHb obtained in steps S1000 and S1002.

And are calculated. The second index value is as described above.

In step S1012, the processing device 70 (support information output unit 703) sets the current user status to the "category" based on each first index value obtained in step S1008 and each second index value obtained in step S1010. It is determined whether or not it can be estimated as 0 ". The estimation method of category 0 is as described above with reference to FIG. 7. If the determination result is "YES", the process proceeds to step S1014, and if not, the process proceeds to step S1016.

In step S1014, the processing device 70 (support information output unit 703) outputs a black mark to the display device 8.

It is determined whether or not it can be estimated as "I". The method for estimating Category I is as described above with reference to FIG. If the determination result is "YES", the process proceeds to step S1018, and if not, the process proceeds to step S1020.

In step S1018, the processing device 70 (support information output unit 703) outputs a red mark to the display device 8.

In step S1020, the processing device 70 (support information output unit 703) sets the current user status to the "category" based on each first index value obtained in step S1008 and each second index value obtained in step S1010. It is determined whether or not it can be estimated as II ". The method for estimating Category II is as described above with reference to FIG.

According to the process shown in FIG. 10, the measured values of pulse wave and ΔHb are simultaneously measured from the biometric information measuring device 1 attached to the finger of the user's hand and the biometric information measuring device 2 attached to the user's forehead. Obtainable. As a result, the user's blood circulation status and blood oxygen balance can be comprehensively evaluated at both the forehead and the fingers of the hand. As a result, the estimation accuracy of each category (consistency with the category judged by the actual doctor) can be improved, and the usefulness of the support information can be enhanced.

By the way, in recent years, resuscitation treatment is performed by CPR (cardiopulmonary resuscitation) or AED (automated external defibrillator) at the site of illness, accident, or critical care. Resuscitation treatment is defined in the JRC resuscitation guidelines, but it is required to quantitatively and easily measure the resuscitation treatment method. It is required to measure peripheral blood circulation and oxygen cycle to the head during CPR cardiopulmonary resuscitation.

In this regard, according to the present embodiment, the optical sensor system in the biometric information measuring device 1 and the biometric information measuring device 2 is a reflection type, and the biometric information measuring device 1 and the biometric information measuring device 2 are used for each part (hand) of the user. It is possible to realize a biometric information measurement system 100 that can be easily used in a life-saving field by simply attaching it to a finger and a forehead. That is, since it can be easily attached and the peripheral blood circulation and oxygen circulation to the head can be measured, it can be attached to the fingers and head (forehead) of the hand at the time of emergency, and to the fingers and head of the hand in a short time. Oxygen circulation can be confirmed.

Especially in the case of critical care, it is important to grasp the oxygen state in the head (forehead), but according to this example, significant biological information (head) for determining whether or not oxygen does not circulate in the brain. Pulse wave and ΔHb) can be output. For example, the above-mentioned category I is a state in which the blood oxygen balance in the head is not good, and such a state can be detected with high accuracy, and support information useful for life-saving emergency can be output.

Further, according to this embodiment, it becomes easy for a doctor or the like to perform prompt and correct resuscitation while observing the blood circulation state and blood oxygen balance of each of the fingers and the forehead of the hand. That is, it becomes easy to perform resuscitation while grasping the recovery of blood circulation during CPR and the state of oxygen circulation to the head. For example, if resuscitation is performed in a state where there is no oxygen cycle in the head (brain), resuscitation may occur in a plant human, but according to this embodiment, such inconvenience can be reduced.

Further, according to the present embodiment, since the measurement data can be transmitted and received by wireless communication, it is possible to eliminate the troublesomeness of wiring at the time of relief. However, in the modified example, wired may be used. In addition, it can measure from children to the elderly, and can be used for sports and non-illness as well as lifesaving.
