    • Provided are a blood sensor that is highly reliable and does not contaminate the interior of the main body of the device, a blood testing device and a blood analysis method. The blood sensor (30) is provided with a plate-shaped base (31), a blood storage part (45) set roughly in the center of the base (31), a supply path (44), one end of which is connected to the storage part (45) and the other end of which is connected to an air pore (43b), multiple detecting electrodes (32-35) laid on one surface of the supply path (44), connecting electrodes (32a-35a), each coming out of these detection electrodes (32-35), and skin detection electrodes (47a, 47b) in the storage part (45) or near the storage part (45). The blood detecting device (101) is provided with a skin detecting circuit (200) that detects skin contact by measuring sensor (30) conduction or impedance changes.

    • A constant voltage supplying circuit including an output transistor is connected to a power source line and an output terminal. A base-emitter voltage of the output transistor is detected by a voltage detecting circuit composed of a transistor. A current-outputting circuit for supplying a current determined based on the voltage detected by the voltage detector to a reference voltage supplying circuit is used in the constant voltage supplying circuit. The reference voltage is supplied to a base of the output transistor to cancel a base-emitter voltage of the output transistor and to equalize the output voltage to a voltage generated in a reference voltage generating element included in the reference voltage supplying circuit. In this manner, the output voltage is kept constant notwithstanding variation of output current.
    • 包括输出晶体管的恒压供电电路连接到电源线和输出端。 输出晶体管的基极 - 发射极电压由由晶体管构成的电压检测电路来检测。 在恒压供给电路中使用用于将基于由电压检测器检测出的电压确定的电流提供给基准电压供给电路的电流输出电路。 参考电压被提供给输出晶体管的基极以消除输出晶体管的基极 - 发射极电压,并将输出电压与在参考电压供应电路中包括的参考电压产生元件中产生的电压相等。 以这种方式,尽管输出电流的变化,输出电压保持恒定。
