Abstract
A body fluid component measuring apparatus capable of accurately measuring a specific component in a body fluid for a short time includes, in a main body, a measuring device for detecting the sampling of a body fluid and measuring a component of the sampled body fluid, and a pump and an electromagnetic valve which constitute an evacuating mechanism. When the sampling of blood is detected, the pump is stopped to release the evacuation state. Another apparatus according to a second aspect includes a pressure detecting means and a notifying device. A puncturing device is operated only when it is decided on the basis of a result of detection by a sensor, that the housing is in an evacuation state, and after the sampling is detected, the evacuation is released and information is notified. A further apparatus according to a third aspect includes a pressure adjusting means for fluctuating the pressure.
