A compact and wearable blood extracting medical device applied for biomimetic medical electronic machine (Bio-MEM) such as a health monitoring system (HMS), was newly developed. This medical device can detect blood sugar level for diabetic patient and inject insulin on a measurement result. This device consists of (1) a microneedle indentation unit using a shape memory alloy (SMA) actuator, (2) a blood extracting unit by restitution rubber, (3) a MOSFET type biosensor by employing Glucose oxidase (GOx) enzyme and (4) a insulin injection unit by restitution rubber. The performances of elements were evaluated as: (2) ability of blood extraction, (3) ability of measure blood sugar level and (4) ability of insulin injection. A blood extracting unit extracted human blood at the flow rate of 0.15μl/sec. Output voltage depended on a blood sugar level with human blood. An insulin injecting unit drained distilled water at the flow rate of 6.5μl/sec. By this study, basic of medical device was newly developed.
