Patent number: 7326180Abstract: A sensor is pressurized adjustably against a patient's wrist and detects a pressurized pulse wave of a radial artery in a noninvasive manner so as to measure blood pressure on an arm band wound around the patient's predetermined portion. A CPU calculates indices reflecting a reflecting phenomenon of a pulse wave as organism information different from the blood pressure based on the detected pulse waveform, and relates the measured blood pressure value with calculated indices so as to display them on an indicator. A doctor checks displayed contents so as to clearly understand a state of a circulatory system represented by a correlation between the patient's blood pressure and the indices so as to be capable of obtaining information which supports a diagnosis and prescription quickly.Type: GrantFiled: December 4, 2003Date of Patent: February 5, 2008Assignee: Omron Healthcare Co., Ltd.Inventors: Kazuhisa Tanabe, Tomoki Kitawaki, Kazunobu Itonaga, Hironori Sato, Masao Hashimoto, Yoshinori Miyawaki

Publication number: 20050033187Abstract: A vital sign detection device is mounted on the wrist of a subject for measurement of vital sign such as pulse wave and blood pressure and has a regulating portion for restricting the movement of the hand during a measurement. The regulating portion extends from a main body of the device toward the distal end of the hand, and may be a plate integral with the main body or the main body itself moved toward the distal end. When the device is used for the detection of pulse waves, the plate may have a band for tying the hand to the plate for preventing rotation of the wrist joint. When the device is used for the measurement of blood pressure, the main body of the device, which is slidably or rotatably transported toward the distal end, may suppress the movement of hand enough to prevent the rise of wrist tendons from hindering the measurement.Type: ApplicationFiled: September 13, 2004Publication date: February 10, 2005Inventors: Kazunobu Itonaga, Kazuhisa Tanabe, Toshio Ohtani, Shojiro Oku, Takahide Tanaka, Yoshihiko Sano, Hiroyuki Kato

Publication number: 20040010199Abstract: A pulse wave monitor includes a sensor unit having a pulse wave sensor and a base. The base of the pulse wave monitor is mounted on a wrist of a subject. A finger or a detector is inserted through the pulse detecting hole provided on the base so as to detect an artery of the subject, and the base is fixed to the wrist of the subject by a belt so that the artery comes to a center of the base. The sensor unit is engaged with the base by a clip. A preliminary position relationship between the sensor unit and the artery is detected. When the position of the sensor unit must be adjusted, the sensor unit is slid to cover a predetermined number of graduations. This adjustment allows the sensor unit to be at an optimal position so that a pulse wave of the subject is measured. As a result, it is possible to provide a pulse wave monitor capable of quickly performing positioning with high accuracy.Type: ApplicationFiled: May 7, 2003Publication date: January 15, 2004Applicant: OMRON CorporationInventors: Masao Hashimoto, Kazunobu Itonaga, Kazuhisa Tanabe, Tomoki Kitawaki, Hiroshi Kishimoto
