Biological information measurement device, biological information measurement method, and biological information measurement system

A biological information measurement method comprising:

• causing a first light emitting element configured to emit red light and a second light emitting element configured to emit infrared light to emit light;
• generating a first light receiving signal based on the red light and a second light receiving signal based on the infrared light;
• operating in a second mode of measuring a pulse wave using the first light receiving signal or the second light receiving signal;
• and
• operating by switching to a first mode of measuring the pulse wave using a third light receiving signal based on green light emitted by a third light emitting element when a switching signal is received.

A biological information measurement system comprising a biological information measurement device and a control device, wherein

• the biological information measurement device includes
• a light emitting unit including a first light emitting element configured to emit red light, a second light emitting element configured to emit infrared light, and a third light emitting element configured to emit green light,
• a light receiving unit configured to receive the red light, the infrared light, and the green light emitted by the light emitting unit, and to generate a first light receiving signal based on the red light, a second light receiving signal based on the infrared light, and a third light receiving signal based on the green light,
• a controller configured to operate the light emitting unit and the light receiving unit, and
• a communication unit configured to transmit the first light receiving signal, the second light receiving signal, and the third light receiving signal,
• the control device includes
• a terminal communication circuit configured to receive the first light receiving signal, the second light receiving signal, and the third light receiving signal, and
• a data controller configured to calculate a pulse wave using any one of the first light receiving signal, the second light receiving signal, and the third light receiving signal, and to evaluate an irregular pulse, and
• the controller operates the light emitting unit and the light receiving unit in a first mode of generating the third light receiving signal or in a second mode of generating the first light receiving signal and the second light receiving signal.
