Abstract
A body fluid measuring apparatus includes a main body ( ) and a body fluid sampler ( ) attached to the main body ( ). The body fluid sampler ( ) includes a fixed member ( ) fixed to the main body ( ) and a movable member guided by the fixed member ( ). The fixed member ( ) is provided with a body fluid-sucking chamber ( ) open at the tip of the fixed member ( ) and a through-hole communicating therewith. The movable member ( ) includes a lancet ( ) acting as a first electrode and is reciprocatively movable for bringing the tip of the lancet ( ) into and out of the tip of the fixed member ( ). The body fluid-sucking chamber ( ) is provided with a second electrode ( ) and a reactive layer containing a reactive reagent necessary for measurement. The main body ( ) includes an electronic circuit ( ) for determining a measured value on the basis of an electrical signal from the lancet ( ) as the first electrode and a second electrode. The main body also includes a drive mechanism ( ) which drives the movable member for causing the tip of the lancet to project from the tip of the fixed member.
