    • A measuring unit is placed at the surface of a living body. The pressure inside of a glass container is reduced by a pressure reducing tank, so that a subcutaneous exuding fluid is taken out at the surface of the living body from under a skin. The subcutaneous exuding fluid is allowed as a sample to be measured to reach a metallic film through porous molecular weight selective films. A light beam emitted from a light source passes through a prism, and then, is reflected on the metallic film, and finally, is received on a linear array sensor. A minimum intensity position on the linear array sensor, generated by surface plasmon resonance is obtained, and then, a resonant angle is detected. The concentration of substance to be measured contained in the sample to be measured is calculated based on the resonant angle and position. Thus, the concentration of a component contained in a bodily fluid can be readily measured for a long time of period in a continuous manner without any special treatment by taking a very small quantity of exuding fluid without any pain.
    • 测量单元放置在活体表面。 玻璃容器内部的压力通过减压槽减少,从而皮肤下皮下渗出的液体在生物体的表面被取出。 允许皮下渗出液作为待测样品通过多孔分子量选择性膜达到金属膜。 从光源发射的光束通过棱镜,然后在金属膜上反射,最后被接收在线性阵列传感器上。 获得由表面等离子体共振产生的线阵列传感器上的最小强度位置,然后检测共振角。 基于谐振角度和位置计算要测量的样品中包含的待测物质的浓度。 因此,容易含有的成分的浓度可以容易地以连续的方式长时间测量,而无需任何特殊处理,通过以非常少量的渗出液无任何疼痛。

    • A portable electrocardiograph (1A) includes a body unit (100) arranged with a negative electrode and a detachable unit (110) arranged with a positive electrode, where the detachable unit (110) is detachably attached to the body unit (100). The negative electrode and the positive electrode are both exposed in a state where the detachable unit (110) is united to the body unit (100). In the portable electrocardiograph (1A), an electrocardiographic waveform can be measured both in a state where the detachable unit (110) is united to the body unit (100) and in a state where the detachable unit (110) is separated from the body unit (100). According to such a configuration, it is possible to obtain the portable electrocardiograph in which a degree of freedom in measuring position is enhanced such that the electrocardiographic waveform can be measured by selecting a specific measuring position from a plurality of measuring positions according to a situation.

    • In a portable electrocardiograph (100), including a negative electrode (121) to be contacted by a hand of a subject and a positive electrode (122) to be contacted to a predetermined measurement site of a subject, for measuring an electric signal detected by the negative electrode (121) and the positive electrode (122) as an electrocardiographic waveform, springs (190a, 190b, 190c, 190d) for supporting the positive electrode (122) in a freely oscillating manner are arranged in a body unit (110) including the negative electrode (121) and a processing circuit for measurement. Thus, a portable electrocardiograph that excels in handleability and that enhances the contacting stability between the electrode and the measurement site can be achieved.
