BIOSENSOR CARTRIDGE, METHOD OF USING BIOSENSOR CARTRIDGE, BIOSENSOR DEVICE, AND NEEDLE INTEGRAL SENSOR
First Claim
1. A biosensor cartridge comprising:
- a biosensor chip, anda puncturing tool fixed to a portion of the biosensor chip and having a tip protruding therefrom, whereinan elastic body having a through hole which contains a sample collection opening provided at a tip of the biosensor chip and a puncture hole formed in a subject by the puncturing tool is provided at a tip of the biosensor chip, andthe elastic body includes a ventilation passage which passes through between an internal wall surface which forms the through hole and an external wall surface of the elastic body.

Abstract
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.
