Document Type and Number:
Japanese Patent JP3985022
Kind Code:
B2
Abstract:
A body fluid measuring apparatus includes a main body (20) and a body fluid sampler (30) attached to the main body (20). The body fluid sampler (30) includes a fixed member (35) fixed to the main body (20) and a movable member guided by the fixed member (35). The fixed member (35) is provided with a body fluid-sucking chamber (39) open at the tip of the fixed member (35) and a through-hole communicating therewith. The movable member (31) includes a lancet (32) acting as a first electrode and is reciprocatively movable for bringing the tip of the lancet (32) into and out of the tip of the fixed member (35). The body fluid-sucking chamber (39) is provided with a second electrode (36) and a reactive layer containing a reactive reagent necessary for measurement. The main body (20) includes an electronic circuit (24) for determining a measured value on the basis of an electrical signal from the lancet (32) as the first electrode and a second electrode. The main body also includes a drive mechanism (43) which drives the movable member for causing the tip of the lancet to project from the tip of the fixed member.
