Abstract

Disclosed is an assistance device which can be used for the puncture into the skin with a puncture tool having a puncture needle and the measurement of a desired component in the blood with a blood glucose monitoring system equipped with a measurement tool. The assistance device comprises a main body which contacts with the skin and a lid which is connected to the main body in a freely openable and closable manner, wherein one of the main body and the lid has a puncture guide for positioning the puncture needle toward a position on the skin to be punctured with the puncture needle, and the other has a blood collection guide for positioning the measurement tool toward the position on the skin punctured with the puncture needle.

Claims

1. An assistance device for puncturing skin with a puncture device having a puncture needle, and measuring a desired blood component with a measurement device on which a measurement tool having a blood sampler is mounted, comprising:

a main body; and

a lid openably and closably joined to said main body,

wherein one of said main body and said lid has a puncture guide for positioning said puncture needle in alignment with a puncture position on the skin, and the other of said main body and said lid has a blood sampling guide for positioning said measurement tool in alignment with a region of the skin which is punctured by said puncture needle.

2. An assistance device according to claim 1, wherein said main body has a bleeding accelerator for pressing the skin upon contact therewith in order to cause blood to flow out from the skin, said bleeding accelerator being of a tapered shape that is progressively greater in diameter in a direction toward the skin.

3. An assistance device according to claim 1, further comprising:

fixing means for fixing said main body to a blood sampling region.

4. An assistance device according to claim 1, further comprising:

biasing means for biasing said lid in an opening direction; and

holding means for holding said lid in a closed state.

5. An assistance device according to claim 1, wherein when said lid is closed, a centerline of a hole of said puncture guide and a centerline of a hole of said blood sampling guide are held in alignment with each other.

6. An assistance device according to claim 1, wherein the cross section of a hole of one of said puncture guide and said blood sampling guide, which is provided on said lid, is included within the cross section of a hole of the other of said puncture guide and said blood sampling guide, which is provided on said main body, in planar projection.

7. An assistance device according to claim 3, wherein said fixing means comprises two curved arcuate ring members which form an annular shape when the ring members engage with each other, and one of the two ring members has sawtooth engaging recesses for adjusting the diameter of said fixing means.

8. An assistance device according to claim 3, wherein said main body is detachably mounted on said fixing means, said assistance device further comprising:

positioning means for positioning said main body with respect to said fixing means in a plurality of orientations.
