Patent number: 7391516Abstract: The present invention provides an optical element for measuring information of living body for noninvasively measuring a body fluid component in a test sample of living body with high accuracy, stability, and ease. The optical element includes a light incident surface, a contact surface contacting living body and having a groove to protrude living body and a light emission surface, in which a light incident from the light incident surface is applied to living body, and the light absorbed and scattered by living body is received and emitted from the light emission surface, a light transmittance controlling means is formed from the bottom part of the valley part of the groove, on at least a part of a wall surface of the light incident surface side and/or on a wall surface of the light emission surface side of the groove.Type: GrantFiled: March 28, 2005Date of Patent: June 24, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masahiko Shioi, Shinji Uchida, Kiyoko Oshima

Patent number: 7215982Abstract: The present invention provides easy and stable measurement of the concentration of a specific component contained in a living body, even when a fluid such as water, saliva or sweat is present between an optical element and the living body or when the measurement is taken at a plurality of measuring parts of a living body. In the measurement of the present invention, a calibration line to be used to correct the influence of a change of a fluid layer present between a living body and an optical element is determined, a measured value is corrected based on the calibration line and the concentration is obtained from the corrected value.Type: GrantFiled: April 2, 2004Date of Patent: May 8, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kiyoko Oshima, Shinji Uchida, Masahiko Shioi

Patent number: 5745165Abstract: A compact and light-weight video scope camera offering easy magnification changing operations. A hollow insert portion continuous to a grip to be held by an operator is provided with an imaging system at the leading end. Operating an operation switch on the grip allows operational movement of a selection mechanism in the insert portion to cyclically or selectively select, from plural preset distance values, a distance between a lens and an image pickup device in the imaging system, corresponding to which distance, the lens or the image pickup device is moved relative to each other by an imaging system component of mechanism to set any one of predetermined magnification modes. This results a compact, light-weight video scope camera offering easy magnification changing operations. The invention is applicable to various video scope cameras for diagnosis and/or treatment in dentistry and orthopedics and also for industrial or educational use.Type: GrantFiled: June 3, 1996Date of Patent: April 28, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroshi Atsuta, Kiyoko Oshima, Kazuo Matsuura
