The portable terminal 100 includes an illuminance sensor 110 and a flash 120 as a general portable personal terminal 100. The illuminance sensor 110 and the tablet PC equipped with the flash 120, It is needless to say that various personal portable terminals 100 can be applied. On the other hand, the illuminance sensor 110 receives reflected light reflected from the bodily fluid to the irradiated light source.

Here, the light source may be a flash 120 of the portable terminal 100. In this case, there is no need to provide a separate apparatus for the configuration of the optical unit, and the structure can be simplified. Meanwhile, the light source may be white light as long as it is in the form of light that can be received by the illuminance sensor 110.

In addition, the light source may be a separate light source element as in the case of using the flash 120. For example, the light source may be installed in the human body insertion unit 200 to emit the light source with the body fluid, A light emitting element or the like can be applied.

The human body insertion unit 200 has a hollow tube shape and one end is inserted into the human body 1 and a light source emitting light from the light source is transmitted and irradiated with the body fluid of the human body 1. The human body insertion portion 200 may include a catheter portion inserted into and supported by the human body 1.

One end of the connection unit 300 is connected to the other end of the human body insertion unit 200 and the other end of the connection unit 300 is connected to the portable terminal 100, So that the light source is transmitted to the human body insertion unit 200 and the illumination sensor 110 detects reflected light reflected from the body fluid in the human body insertion unit 200.
