Publication number: 20090299225Abstract: There is provided a biosensor chip where the collecting amount necessary for the measurement is made small whereby burden of a user is reduced and, at the same time, a sample at a puncture opening is able to be easily collected and measured without an operation of making the sample collection opening nearer the puncture opening. When an end of a main body chip is pushed onto a test body, an elastic body installed at an end of the main body chip is compressed and a device for puncture is produced whereby the test body is able to be punctured. When the pushing force is made weak, the device for puncture is pulled out from the test body due to resilience of the elastic body and a sample is flown out from the puncture opening.Type: ApplicationFiled: April 17, 2007Publication date: December 3, 2009Applicant: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Takahiko Kitamura, Shingo Kaimori, Akira Harada, Toshifumi Hosoya, Tsuyoshi Fujimura, Isao Karube, Masao Gotoh, Hideaki Nakamura, Tomoko Ishikawa
