Body fluid sampling unit
First Claim
1. A method of obtaining a body fluid sample from a living body and using the body fluid sample comprising:
- removing a body fluid sampling implement from an interior of a container, the body fluid sampling implement comprising a reagent containing part comprising a reagent adapted to interact with a predetermined component in the body fluid, the interior of the container also containing a needle possessing a sharp needle point at a distal end of the needle;
mounting the body fluid sampling implement on a component measuring device, the component measuring device being adapted to measure at least one of a quantity and a property of the predetermined component of the body fluid obtained by the body fluid sampling implement;
the body fluid sampling implement being removed from the interior of the container either before mounting the body fluid sampling implement on the component measuring device or after mounting the body fluid sampling implement on the component measuring device;
puncturing a surface of the living body with the needle by moving the needle relative to the container to produce a body fluid sample; and
introducing to the reagent containing part of the body fluid sampling implement the body fluid sample obtained by puncturing the surface of the living body with the needle so that the reagent interacts with the predetermined component in the body fluid sample.

Abstract
A body fluid sampling unit includes a puncture device including a needle having a sharp needle point and a drive mechanism for operating the needle to puncture a living body surface with the needle point, a tip including an introducing section for introducing a body fluid flowing out from a puncture portion of the living body surface punctured with the needle point, a test paper for detecting a predetermined component in the body fluid, and a tip body mounted to a component measuring device for measuring the quantity and/or property of the predetermined component detected by the test paper; and a case including a mechanism containing section for containing the puncture mechanism so that the needle point of the puncture mechanism can be moved by the drive means, and a sampling implement containing section for containing the body fluid sampling implement so that the tip can be taken out.

6. A method of obtaining a body fluid sample from a living body and using the body fluid sample comprising:
-
positioning a body fluid sampling implement on a component measuring device, the body fluid sampling implement being located inside a container in a gas-tight environment before the body fluid sampling implement is positioned on the component measuring device, the body fluid sampling implement being configured to obtain a sample of the body fluid and including a reagent containing part comprising a reagent adapted to interact with a predetermined component of the sample of the body fluid, the component measuring device being configured to be operated, when the body fluid sampling implement is positioned on the component measuring device, to measure at least one of a quantity and a property of the predetermined component of the sample of the body fluid obtained by the body fluid sampling implement; puncturing a surface of the living body with a needle located inside the container by moving the needle relative to the container to produce the body fluid from which the body fluid sampling implement obtains the sample of the body fluid; and introducing the sample of the body fluid to the reagent containing part of the body fluid sampling implement so that the reagent interacts with the predetermined component in the body fluid sample. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method of obtaining a body fluid sample from a living body and using the body fluid sample comprising:
-
moving a body fluid sampling implement from a housed position to an un-housed position, the body fluid sampling implement in the housed position being located inside a case such that an outer periphery of the body fluid sampling implement contacts an inner periphery of the case so that the contact between the case and the body fluid sampling implement prevents a force applied to the case from releasing an engagement between a part of the case and an engaging piece, the body fluid sampling implement in the un-housed position being outside the case so that the outer periphery of the body fluid sampling implement is not in contact with the inner periphery of the case, the body fluid sampling implement including a reagent containing part comprising a reagent adapted to interact with a predetermined component of a sample of the body fluid, the engaging piece being located inside the case and connected to a needle possessing a sharp distal end; applying a force to the case after the body fluid sampling implement is moved to the un-housed position to cause the engaging piece to be disengaged from the case, and moving the needle when the engaging piece is disengaged from the case; puncturing a surface of the living body with the sharp distal end of the moving needle to obtain the body fluid; and introducing a sample of the body fluid obtained by the puncturing to the reagent containing part of the body fluid sampling implement so that the reagent interacts with the predetermined component in the body fluid sample. - View Dependent Claims (18, 19, 20)
