Our health monitoring system (HMS) consists of 1) the painless blood extraction, 2) the handy type automatical blood extraction, and 3) the continuous measurement in blood sugar level by insulin administering. In this study, a vacuum extracting type device for the blood sugar measurement is newly developed, which employ a handy type automatical blood extraction system, such as a mobile HMS for the diabetes patients. The vacuum extracting blood unit, which is built in this vacuum extracting type HMS device, consists of a) the puncture part, b) the extraction part, and c) the base part, and succeeds in extracting 12.7μl of human blood within 2 seconds.
