It is possible for the user to freely select or create, and the usage method that has been fixed as a conventional system can be made extremely flexible. Furthermore, since only a blood volume sensor and a signal conversion device are needed as a dedicated device, it is possible to reduce the price significantly, and it is possible to make it easily available to general households. This makes it possible to easily obtain high-level medical information at home that could only be obtained through specialists, and to use it for health management in general households.

ある。Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In FIG. 1, reference numeral 1 denotes a blood volume sensor, which has a light emitting portion 11 made of a tungsten lamp and the like and a light receiving portion 12 made of Cds and the like. Is to be detected automatically.
Reference numeral 2 is a signal conversion device, which converts the output of the blood volume sensor 1 into an input signal to the general-purpose personal computer 3. 21 is an amplifier, 22 is a gain adjuster, and 23 is A
D converters, which are built in the signal converter 2. In FIG. 2, reference numeral 4 denotes a connector, which is a device for connecting the signal conversion device 2 and the general-purpose personal computer 3.

れる。Next, the operation of the above configuration will be described. When the person to be measured inserts his / her fingertip into the blood volume sensor 1, the light emitted from the light emitting unit 11 passes through the fingertip and reaches the light receiving unit 12. At this time, since the blood portion in the fingertip does not transmit light, the amount of light reaching the light receiving unit 12 changes according to the increase or decrease in the blood amount in the fingertip. It is medically clear that the blood volume in the fingertip changes depending on the operating state of the heart, elasticity of blood vessels in various parts of the body, and the like, and the health condition can be known based on the increase or decrease in the blood volume. Next, the output signal from the blood volume sensor 1 is input to the signal converter 2 as an electric signal, and the amplifier 21
Is amplified by and is adjusted to an electric signal of an appropriate level by the action of the gain adjuster 22. Further, this electric signal is converted into a digital signal by the AD converter 23 and input to the general-purpose personal computer 3 via the connector 4, and is processed by the general-purpose personal computer 3 according to the purpose of the user.
