Patent number: 7270476Abstract: An electronic clinical thermometer has one of two temperature measuring devices each for measuring a live body temperature. A temperature estimating device estimates an equilibrium body temperature from a first data item related to change in temperature measured by the temperature measuring device during an initial period within a specified time such as about 20 seconds from the start of a measurement and a second data item related to a change in temperature measured by the temperature measuring device after the initial period. If two temperature measuring devices are used, the first data item may be related to the difference between temperatures measured by these two temperature measuring devices and the second data item may be related to the time-rate of change in temperature measured by either of the two temperature measuring devices.Type: GrantFiled: April 30, 2004Date of Patent: September 18, 2007Assignee: OMRON Healthcare Co., Ltd.Inventors: Muneo Tokita, Shigeru Tomioka

Patent number: 7016021Abstract: A measuring unit is placed at the surface of a living body. The pressure inside of a glass container is reduced by a pressure reducing tank, so that a subcutaneous exuding fluid is taken out at the surface of the living body from under a skin. The subcutaneous exuding fluid is allowed as a sample to be measured to reach a metallic film through porous molecular weight selective films. A light beam emitted from a light source passes through a prism, and then, is reflected on the metallic film, and finally, is received on a linear array sensor. A minimum intensity position on the linear array sensor, generated by surface plasmon resonance is obtained, and then, a resonant angle is detected. The concentration of substance to be measured contained in the sample to be measured is calculated based on the resonant angle and position.Type: GrantFiled: May 19, 2003Date of Patent: March 21, 2006Assignee: Omron CorporationInventors: Satoshi Nakajima, Muneo Tokita, Yusaku Sakoda
