Abstract: The present invention is directed to a biosensor being provided with a suction cavity which sucks a certain amount of sample by means of capillary phenomenon, the biosensor including a flow channel to connect the suction cavity and an analytical cavity furnished with a reagent, wherein, the flow channel has a narrowed section provided with a gap formed by narrowing a flow passage area. The narrowed section has a function to retain the sample in the suction cavity when the sample is sucked therein, and a function to circulate the sample retained in the suction cavity into the analytical cavity through the gap, when a centrifugal force is applied from the outside. The two functions held by the narrowed section enables a simple collection of blood sample, and further enables a simple transfer of the blood sample to the analytical area by applying the centrifugal force to the blood sample, as well as facilitating a component extraction.

Abstract: Both application of centrifugal force to a biosensor and electrical connection with an electrode of the biosensor can be achieved with a simple structure. The electrode of the biosensor and a measuring part are connected without aligning a rotational position of the rotary table. The centrifugal measuring apparatus 1 is provided with a rotary table 2 that is driven by a motor, a retainer 3 to hold a biosensor accommodating a sample inside on the rotary table, an urged contact part 4 that establishes electrical connection with the electrode of the biosensor in such a manner as being elastically biased to abut against the electrode, a measuring part 8 that measures a signal from the electrode of the biosensor, and a connector part 7 that selectively establishes electrical connection between the urged contact part 4 and the measuring part 8.

Abstract: To provide a radiation thermometer capable of measuring a body temperature more accurately than it has been conventionally possible, by taking into account an infrared ray that is emitted from a front end of the probe portion and reflected from an eardrum or an external acoustic opening. The radiation thermometer has body temperature calculating means for calculating a body temperature according to a predetermined arithmetic expression based on an emissivity when the emissivity of the eardrum or the external acoustic opening is less than 1, an output of infrared-ray detecting means and an output of temperature-measuring means.
