Publication number: 20100069792Abstract: A biosensor cartridge capable of performing puncturing in an exact position, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When tip portion 11a of biosensor chip body 11 is pushed against a subject M, elastic body 20 protruding from a tip portion 11a of biosensor chip body 11 is compressed, and puncturing tool 12 for puncturing protrudes. Thus, the subject M can be punctured. Additionally, if a pushing force is weakened, puncturing tool 12 is extracted from the subject M by the restoring force of elastic body 20, and the sample R flows out of the puncture hole. Additionally, cover member 19 is provided around biosensor chip body 11. Thus, when puncturing is performed by thin plate-shaped biosensor cartridge 10, biosensor chip body 11 can be prevented from deforming, and puncturing can be accurately performed in a desired puncturing position.Type: ApplicationFiled: November 1, 2007Publication date: March 18, 2010Applicants: National Institute of Advanced Industrial Science and Technology, Sumitomo Electric Industries, Ltd.Inventors: Tsuyoshi Fujimura, Hideaki Nakamura, Tomoko Ishikawa, Masao Gotoh, Isao Karube, Takahiko Kitamura, Shingo Kaimori, Akira Harada, Hiroto Nakajima, Hiroshi Hayami, Toshifumi Hosoya

Publication number: 20100004559Abstract: A biosensor cartridge capable of making the collected amount of a sample required for measurement into a small quantity to reduce a user's burden, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When one end portion of biosensor chip is pushed against subject, elastic body is compressed, and puncturing tool can protrude and perform puncturing. Additionally, if a pushing force is weakened, puncturing tool is extracted from subject by the restoring force of elastic body, and blood (sample) flows out of the puncture hole. In this case, since the puncture hole, and sample collection opening provided at biosensor chip are contained in enclosed half-open space formed by elastic body, even a small amount of blood (sample) can also be easily collected.Type: ApplicationFiled: December 17, 2007Publication date: January 7, 2010Applicants: NATIONAL INSTITUTE OF ADVANCED INDUSTRIAL SCIENCE AND TECHNOLOGY, SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Tsuyoshi Fujimura, Hideaki Nakamura, Masao Gotoh, Isao Karube, Tomoko Ishikawa, Takahiko Kitamura, Shingo Kaimori, Hiroto Nakajima, Hiroshi Hayami, Toshifumi Hosoya
