20090299225 | BIOSENSOR CHIP - 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. At that time, since the puncture opening and the sample collection opening installed in the main body chip are enclosed in a tightly-closed space formed by the elastic body, even small amount of the sample is able to be easily collected by the sample collection opening without conducting the positioning of the sample collection opening. | 12-03-2009 |
20100004559 | BIOSENSOR CARTRIDGE, METHOD OF USING BIOSENSOR CARTRIDGE, BIOSENSOR DEVICE, AND NEEDLE INTEGRAL SENSOR - 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. Additionally, elastic body is formed with a groove which forms a ventilation passage, so that enclosed half-open space can be opened to the atmosphere. | 01-07-2010 |
