For the functions of the first index value generation unit 701, the second index value generation unit 702, and the support information output unit 703, the CPU 71 executes one or more programs in a storage unit such as the ROM 73 or the auxiliary storage device 74, for example. It can be realized by

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

The first index value is, for example, an index value representing a good degree of blood circulation. The first index value may be calculated from any one, a combination of two, or all combinations of the pulse rate that can be derived from the pulse wave, the pulse amplitude, and the pulse interval. In the present embodiment, as an example, the first index value has three levels (“absent”, “weak”, and “not” whether the pulse rate is significantly higher than 0 and whether it exceeds a predetermined threshold Th1. Indicates "Yes"). Specifically, the first index value is a value representing "absent" when the pulse rate is approximately 0, and "weak" when the pulse rate is significantly higher than 0 but lower than a predetermined threshold Th1. It is a value representing ", and it is a value representing" presence "when the pulse rate is higher than a predetermined threshold Th1.

The second index value generation unit 702 is configured to calculate a second index value (hereinafter referred to as “periphery” hereinafter) related to a balance between oxyhemoglobin and deoxyhemoglobin (hereinafter also referred to as “blood oxygen balance”) based on ΔHb of the peripheral part. And a second index value related to blood oxygen balance (hereinafter also referred to as “second head index value”) based on ΔHb of the head). Do.

The second index value is, for example, an index value representing the significance of the concentration of oxyhemoglobin to the concentration of deoxyhemoglobin. In this embodiment, as an example, the second index value indicates whether the concentration of oxyhemoglobin (or the sum of the concentration with deoxyhemoglobin) is significantly higher than 0, and from the concentration of oxyhemoglobin, deoxyhemoglobin The difference obtained by subtracting the concentration (hereinafter referred to as "oxy-deoxy difference") represents three stages ("none", "weak", and "presence") whether or not a predetermined threshold Th2 is exceeded. Specifically, the second index value is a value representing "absent" when the concentration of oxyhemoglobin is approximately 0, and the oxy-deoxy difference at a concentration of oxyhemoglobin significantly greater than 0 is a predetermined threshold value Th2 If smaller than the threshold value, it is a value representing "weak", and if the oxy-deoxy difference is larger than a predetermined threshold Th2, it is a value representing "presence".

In this case, the support information output unit 703 outputs a black mark indicating that the possibility of the apnea group (without vital signs) is high as the support information to the display device 8, for example.

In addition, the first index value in the peripheral area and the first index value in the head are both "weak" as the blood circulation state, and the second index value in the peripheral area is "weak" as the blood oxygen balance, and the head is When the second index value of 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, a red mark indicating that the possibility of the highest priority treatment group (serious life-threatening condition) is high as the support information to the display device 8.

In addition, the first index value of the peripheral part is "present", the first index value of the head is "weak" as the blood circulation state, and the second index value of the peripheral part is "present" as the blood oxygen balance. If 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, to the display device 8, a yellow mark indicating that the possibility of the standby treatment group (the state to be treated early) is high, for example, as the support information.

In addition, both the first index value of the peripheral part and the first index value of the head are "valid" as the blood circulation state, and the second index value of the peripheral part and the second index value of the head as blood oxygen balance When both are “present”, 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, to the display device 8 as a support information, for example, a green mark indicating that the possibility of the holding group (the state where there is no need for treatment or transport immediately) is high.

In FIG. 7, each color of the mark corresponds to each color of the triage. This makes it possible to output support information that is easy for medical staff to understand. However, in the modification, a category to be estimated may be output as the support information instead of or in addition to the color of the mark, or voice or the like other than display may be output.

By the way, in recent years, resuscitation treatment may be performed by a cardiopulmonary resuscitation (CPR: Cardio Pulmonary Resuscitation) or an automatic external defibrillator (AED: Automated External Defibrillator) at an illness, an accident, a critical care site. Although resuscitation treatment is defined, for example, in the resuscitation guidelines of the Japan Resuscitation Council (JRC: Japan Resuscitation Council), it is required that the resuscitation treatment method be measured quantitatively and simply. During CPR, it is required to measure peripheral blood circulation and oxygen circulation to the head.

In this respect, according to the present embodiment, the optical sensor system in the biological information measuring device 1 and the biological information measuring device 2 is a reflection type, and the biological information measuring device 1 and the biological information measuring device 2 are each part of the user (for example, It is only necessary to attach it to the finger and forehead of the hand, and it is possible to realize the biological information measurement system 100 that can be easily used at the lifesaving site. That is, since it can be easily worn and the peripheral blood flow circulation and oxygen circulation to the head can be measured, it is worn on the finger and head (for example, forehead) of the hand at the time of critical care and the finger and head of the hand in a short time The oxygen circulation to can be confirmed.

It is desirable to grasp the state of oxygen at the head (for example, forehead) especially at the time of critical care, but according to this embodiment, significant biological information (for example, for determining whether oxygen does not circulate in the brain) The pulse wave of the head and ΔHb) can be output. For example, the above-described category I is a state in which the blood oxygen balance in the head is not good, such a state can be accurately detected, and support information useful for critical care can be output.

That is, it becomes easy to perform resuscitation of the patient while grasping the blood flow circulation recovery during CPR and the oxygen circulation state to the head. For example, if resuscitation is performed without oxygen circulation to the head (specifically, the brain), the patient may fall into the vegetative state, but according to the present embodiment, the patient tends to fall into such a vegetative state It can reduce the occurrence of situations.

Moreover, according to the present embodiment, since measurement data can be transmitted and received by wireless communication, it is possible to eliminate the troublesomeness of wired communication at the time of relief.
