Abstract

A blood-collection position indicator facilitating blood collection is provided. An adhesive layer is positioned on the back face of a substrate portion having a convex cross section and a circular planar shape, and at its center, a through hole going through the substrate portion and the adhesive layer is provided to serve as a blood collection hole, thus obtaining a blood-collection position indicator. In the blood-collection position indicator, the protruding portion serves as an attachment part to be attached to the tip of a lancet device, and the protruding portion is inserted into a hole of the tip of the lancet device, thus attaching the blood-collection position indicator to the tip of the lancet device. Adhesive strength of the adhesive layer to the skin is set to be stronger than attachment strength of the attachment part to the tip of the lancet device. Consequently, only the first blood-collection position indicator remains on the skin after the lancet device is used. By using the blood-collection position indicator as a mark, blood can be collected from the blood collection hole.

Claims

1. A blood-collection position indicator, comprising:

an adhesive portion to be stuck to skin;

an attachment part, into which a tip of a lancet device including a lancet is attached; and

a blood collection hole,

wherein the blood-collection position indicator is attached to the tip of the lancet device in a state where the lancet is arranged to pass through the blood collection hole before the lancet device is used, and wherein the adhesive strength of the adhesive portion to the skin is stronger than the attachment strength of the attachment part to the tip of the lancet device, whereby in use, the blood-collection position indicator adheres to and remains on the skin after the lancet device is used.

2. The blood-collection position indicator according to claim 1, wherein the blood collection hole serves as the attachment part and the tip of the lancet device is inserted into the blood collection hole, thus attaching the blood-collection position indicator to the tip of the lancet device.

3. The blood-collection position indicator according to claim 1, further comprising a protruding portion as the attachment part, wherein the protruding portion is inserted into a hole of a tip of the lancet device, thus attaching the blood-collection position indicator to the tip of the lancet device.

4. The blood-collection position indicator according to claim 1, wherein the blood-collection position indicator has a cylindrical shape with a bottom and an inner space of the cylindrical shape serves as the attachment part, the tip of the lancet device is inserted into the inner space, thus attaching the blood-collection position indicator to the tip of the lancet device, the bottom is provided with a through hole serving as the blood collection hole, and an outer bottom face of the bottom is provided with the adhesive portion.

5. The blood-collection position indicator according to claim 4, wherein an inner circumferential face of a cylindrical portion with the cylindrical shape with a bottom has at least one groove along a depth direction, a part of a peripheral surface of the tip of the lancet device is brought into contact with and is pressed against a portion except for the groove of the inner circumferential face, thus attaching the blood-collection position indicator to the tip of the lancet device in a pressure contact state, and the part being in contact with and being pressed against the portion is movable to be positioned in the groove, thus releasing the pressure contact state.

6. The blood-collection position indicator according to claim 5, wherein the tip of the lancet device has a rectangular shape, and corners of the tip are brought into contact with and are pressed against the portion except for the groove of the inner circumferential face of the cylindrical portion.

7. The blood-collection position indicator according to claim 5, wherein the tip of the lancet device has an elliptical shape, and side ends of the tip in a major axis direction are brought into contact with and are pressed against the portion except for the groove of the inner circumferential face of the cylindrical portion.

8. The blood-collection position indicator according to claim 1, wherein the blood collection hole includes a portion with a tapered shape expanding in a direction away from the skin, in use.

9. The blood-collection position indicator according to claim 1, wherein a surface to be brought into contact with the tip of the lancet device is provided with an adhesive portion serving as the attachment part, and the blood-collection position indicator is attached to the tip of the lancet device through the adhesive portion.

10. The blood-collection position indicator according to claim 1, wherein an annular protruding portion surrounding the blood collection hole is provided on a surface to be positioned to face the skin.

11. The blood-collection position indicator according to claim 1, wherein the blood collection hole has a quantitative function.

12. The blood-collection position indicator according to claim 1, further comprising a cover layer on a surface of the adhesive portion, to be stuck to the skin, wherein the cover layer is removable before the adhesive portion is stuck to the skin.
