Body fluid sampling unit
First Claim
1. A body fluid sampling unit comprising:
- a container having an interior;
a needle positioned in the interior of the container, the needle possessing a sharp needle point at a distal end of the needle;
at least one spring positioned in the interior of the container;
the at least one spring being operatively engageable with the needle and being configured to accumulate a spring bias to be applied to the needle to move the needle in a puncturing direction to puncture a living body surface with the needle point;
a body fluid sampling implement removably positioned in the interior of the container;
the body fluid sampling implement comprising;
an introducing section for conveying body fluid flowing out from a puncture portion of the living body surface punctured with the needle point;
a reagent containing part positioned adjacent the introducing section to receive the body fluid conveyed by the introducing section, the reagent containing part comprising a reagent adapted to interact with a predetermined component in the body fluid; and
a mounted section configured to be mounted to a component measuring device for measuring a quantity and/or property of the predetermined component; and
wherein the container comprises an inner tube movably positioned within an outer tube, the body fluid sampling implement being positioned inside the inner tube, the outer tube comprising first and second openings, the inner tube comprising a pawl engaging the first opening, the body fluid sampling implement being configured to be mounted to the component measuring device while the body fluid sampling implement is contained in the sampling implement containing section by pushing the component measuring device towards the body fluid sampling implement to engage the body fluid sampling implement with the component measuring device, said pushing causing the inner tube to move within the outer tube to cause the pawl to be released from the first opening and to engage the second opening.
