Abstract: A body fluid component measuring system which is capable of continuous measurement and reduces downtime includes a sensor unit which is positionable indwelling in the skin of a subject and which measures a predetermined body fluid component included in the body fluid of the subject; and a transmission unit which is detachably attached to the sensor unit and which calculates blood glucose level based on measurement data measured by the sensor unit, and transmits the calculated blood glucose level to a display unit. Identification information for establishing communication between the transmission unit and the display unit is stored in the sensor unit, and the transmission unit, upon activation, uses the identification information read out by the sensor unit to establish communication with the display unit.

Abstract: A device for receiving a transmitting unit that is detachably attachable to a sensor unit configured to be placed on a subject to acquire a biosignal of the subject and that acquires bio-information from the biosignal acquired in the sensor unit to transmit the biosignal to an external device. This device has first and second ports on which transmitting units can be placed, and communication sections each provided in a respective one of the ports to carry out communication with the transmitting units mounted on the respective ports. When the transmitting unit is newly mounted on one port, the device acquires transmission data including communication identification information for the transmission from the newly mounted transmitting unit by the communication section of this port and transmits the acquired transmission data to another transmitting unit already mounted on the other port by using the communication section provided in the other port.

Abstract: In a bodily fluid component measurement system, the convenience for a subject is improved by achieving reductions in size and weight of a device which is always attached at the position where a sensor is indwelled. A bodily fluid component measurement system includes a sensor unit which is indwelled in the skin of a subject to measure a predetermined bodily fluid component, and a transmission unit which is detachably attached to the subject, and transmits, to a display unit, a measurement signal obtained by the sensor unit. The sensor unit is activated upon receiving power supplied by an electromagnetic wave generated by the transmission unit to measure the bodily fluid component and transmit the measurement signal to the transmission unit.

Abstract: The waterproof property of a bodily fluid component measurement system is improved. A bodily fluid component measurement system according to this invention includes a sensor unit which is indwelled in the skin of a subject and connected to a bodily fluid in the subject to measure a predetermined bodily fluid component, and a transmission unit which is detachably attached to the sensor unit and transmits, to a display unit, a measurement signal obtained by the sensor unit or a calculation result calculated as a concentration of the bodily fluid component in a bodily fluid of the same type as or different type from the bodily fluid based on the measurement signal. The sensor unit measures the bodily fluid component and transmits the measurement signal to the transmission unit by being activated by electromagnetic induction caused by an electromagnetic field generated by the transmission unit.

Abstract: A blood pressure measuring apparatus includes a cuff which is attached to and around an external ear; a first pulse wave detector and a second pulse wave detector which detect a pulse wave in a part squeezed by the cuff and which are affected differently from each other by a characteristic of body movements; a body movement detecting means which detects the characteristic of body movements; a pulse wave selecting means which selects a pulse wave detected by one of the first pulse wave detector and the second pulse wave detector based on the characteristic of body movements detected by the body movement detecting means; and a blood pressure value deriving means which derives a blood pressure value based on the pulse wave selected by the pulse wave selecting means.

Abstract: To provide a technique which makes it possible to obtain a proper pulse wave signal for high-accuracy blood pressure measurements, thereby saving the trouble of taking measurements repeatedly and reducing a physical burden imposed on the user by cuff pressure.

Abstract: This invention provides a blood pressure measuring apparatus capable of deriving an appropriate pressure value even in an environment in which the environmental temperature constantly changes.
