  • Biological analysis device, biological analysis method, and program
    Patent number: 11317873
    Abstract: A biological analysis device includes an average blood pressure calculation unit that calculates an average blood pressure index related to an average blood pressure of a biological body in accordance with a blood vessel diameter index related to a blood vessel diameter of the biological body and a blood flow index related to a blood flow of the biological body and calculated from an intensity spectrum related to a frequency of light reflected and received from an inside of the biological body through radiation of a laser beam.
    Type: Grant
    Filed: August 16, 2018
    Date of Patent: May 3, 2022
    Assignee: SEIKO EPSON CORPORATION
    Inventors: Kohei Yamada, Ayae Sawado, Akiko Yamada, Megumi Enari, Yuta Machida, Akira Ikeda, Masayasu Fukuoka, Akira Kitahara
  • Pulse pressure and blood pressure analysis device, pulse pressure and blood pressure analysis method, and program
    Patent number: 11253205
    Abstract: A biological analysis device includes: a pulse pressure calculation unit that calculates a pulse pressure index related to a pulse pressure of a biological body; an average blood pressure calculation unit that calculates an average blood pressure index related to an average blood pressure of the biological body; and a blood pressure calculation unit that calculates a systolic blood pressure and a diastolic blood pressure in accordance with the pulse pressure index and the average blood pressure index. At least one of the pulse pressure index and the average blood pressure index is calculated in accordance with a blood flow index which is calculated from an intensity spectrum related to a frequency of light reflected and received from an inside of the biological body through radiation of a laser beam and is related to a blood flow of the biological body.
