Body fluid sampling unit
First Claim
1. A body fluid sampling unit comprising:
- a puncture mechanism comprising a needle possessing a sharp needle point at a distal end of the needle, and drive means for operating the needle to puncture a living body surface with the needle point;
a body fluid sampling implement comprising 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 detecting section for detecting a predetermined component in the body fluid introduced through the introducing section, and a mounted section configured to be mounted to a component measuring device for measuring at least one of a quantity and a property of the predetermined component detected by the detecting section;
a container comprising a mechanism containing section containing the puncture mechanism so that the needle point of the puncture mechanism is movable by the drive means, and a sampling implement containing section containing the body fluid sampling implement in a manner allowing the body fluid sampling implement to be removed from the sampling implement containing section; and
the puncture mechanism is put into a state of being prepared to perform an operation of puncturing the living body surface by removal of the body fluid sampling implement from the sampling implement containing section.

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.

7. A body fluid sampling unit comprising:
-
a case on which is supported a movable plate piece; a needle positioned inside the case, the needle possessing a sharp needle point at a distal end of the needle for puncturing living body tissue to obtain body fluid; a body fluid sampling implement configured to be mounted on a component measuring device which is adapted to measure at least one of a quantity and a property of a predetermined component of a sample of the body fluid obtained by the puncturing of the living body tissue, the body fluid sampling implement comprising a reagent containing part that includes a reagent adapted to interact with the predetermined component of the sample of the body fluid; a spring positioned to apply a biasing force to the needle urging the needle from a housed position in which the sharp needle point is housed inside the case to a puncturing position in which the sharp needle point is exposed outside the case to puncture the living body tissue; an engaging piece connected to the needle, the engaging piece being shiftable from an engaged position in which the engaging piece engages the plate piece so that the needle remains in the housed position and the biasing force applied to the needle does not move the needle toward the puncturing position to a released position in which the engaging piece moves out of engagement with the plate piece so that the biasing force applied to the needle moves the needle toward the puncturing position, the engaging piece being movable from the engaged position to the released position in response to movement of the plate piece; the body fluid sampling implement being positioned in the case in contact with the plate piece so that the contact between the plate piece and the body fluid sampling implement prevents a force applied to the plate piece from resulting in the movement of the plate piece which causes the engaging piece to shift from the engaged position to the released position; and the body fluid sampling implement being removable from the case so that the biasing force applied to the plate piece results in the movement of the plate piece which causes the engaging piece to shift from the engaged position to the released position to permit the needle to move toward the puncturing position under the biasing force of the spring. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A body fluid sampling unit comprising:
-
a case possessing an interior and an opening at a distal end of the case; a needle positioned in the interior of the case, the needle possessing a sharp needle point at a distal end of the needle for puncturing living body tissue to obtain body fluid; a body fluid sampling implement configured to be mounted on a component measuring device which is adapted to measure at least one of a quantity and a property of a predetermined component of a sample of the body fluid obtained by the puncturing of the living body tissue, the body fluid sampling implement comprising a test paper containing a reagent adapted to interact with the predetermined component of the sample of the body fluid; a spring applying a biasing force to the needle urging the needle from a housed position in which the sharp needle point is housed in the interior of the case to a puncturing position in which the sharp needle point extends distally beyond the opening at the distal end of the case; the body fluid sampling implement being positioned in the case in contact with a portion of the case and being removable from the case so that the body fluid sampling implement is not in contact with the portion of the case; the needle being prevented from moving to the puncturing position from the housed position under the biasing force of the spring whenever the body fluid sampling implement is positioned in the case in contact with a portion of the case; and the needle being permitted to move from the housed position to the puncturing position under the biasing force of the spring when the body fluid sampling implement is removed from the case so that the body fluid sampling implement is not in contact with the portion of the case. - View Dependent Claims (16, 17, 18, 19, 20)
