  • Patent number: 8663579
    Abstract: This invention provides a biological component-measuring device, enabling the operator to easily calibrate the entire device and capable of measuring biological components accurately, and a method for calibrating the device. The device measures a sample including a body fluid taken through a body fluid sampler by sending it with a pump through a sample channel to a sensor. The device further includes a calibrating liquid channel through which a calibrating liquid can be supplied to the sensor via the sample channel by a switching of a first flow path changeover valve placed in the sample channel at a location upstream of the pump and connected to the channel. The method includes introducing the calibrating liquid in the calibrating liquid channel, via other channels, into the sensor by switching the valve.

  • Patent number: 8340739
    Abstract: This invention provides a monitor device capable of detecting possible abnormalities in body fluid withdrawal by a body fluid sampler and variations in the dilution when a withdrawn body fluid is diluted, and a living organism-measuring device with this monitor device. The former device includes a first optical sensor disposed on a diluent channel through which a diluent is introduced into a body fluid sampler for withdrawing a body fluid; a second optical sensor disposed on a diluted body fluid channel through which the diluted body fluid is transferred to a living organism-measuring sensor, and close to the first optical sensor; and a controlling unit for judging whether variations in a dilution to which the body fluid is diluted are within predetermined limits, from data outputted by the first optical sensor and data outputted by the second optical sensor. The latter device has the monitor device incorporated thereto.
