Patent number: 11187712Abstract: The present invention makes it possible for an automated analyzer including two or more types of photometers to obtain suitable output of the measurement results of the plurality of photometers and suitable data alarm output even if there is an abnormality, or the like, at the time of measurement. This automated analyzer includes, for example, two types of photometers having different quantitative ranges and an analysis control unit for controlling analysis that includes measurement of a given sample using the two types of photometers. If two types of data alarms corresponding to abnormalities, or the like, during measurement have been added to the two types of measurement results from the two types of photometers, the analysis control unit selects measurement result and data alarm output corresponding to the combination of the two types of data alarms and outputs the same to a user as analysis results.Type: GrantFiled: September 6, 2018Date of Patent: November 30, 2021Assignee: Hitachi High-Technologies CorporationInventors: Yuto Kazama, Masahiko Iijima, Chie Yabutani, Kenji Kogure

Patent number: 11060967Abstract: Biomarkers of high blood pressure are measured to identify high blood pressure of the subject based on one or more biomarkers. In many embodiments, the response of the biomarker to blood pressure occurs over the course of at least an hour, such that the high blood pressure identification is based on a cumulative effect of physiology of the subject over a period of time. The methods and apparatus of identifying high blood pressure with biomarkers have the advantage of providing improved treatment of the subject, as the identified biomarker can be related to an effect of the high blood pressure on the subject, such as a biomarker corresponding to central blood pressure. The sample can be subjected to increases in one or more of pressure or temperatures, and changes in the blood sample measured over time.Type: GrantFiled: June 12, 2017Date of Patent: July 13, 2021Assignee: NUEON INC.Inventors: Robert G.
