Abstract
In clinical situation, blood sampling is frequently performed for blood test. Recently, most procedures of blood test have been automated and the test system is developing on a chip-sized structure such as μ-TAS. Achievement of complete automatic blood test system combined with venepuncture device and blood test system would bring decrease of blood sampling volume and realization of home blood test. As an automatic venepuncture device, we developed a control system of needle puncture that measured force and electric impedance acting on a needle tip. To obtain information that the needle tip pierced into the blood vessel, the changes in puncture force and electric impedance were evaluated.
