Abstract

An adaptor for body fluid measurement of the present invention includes a puncture instrument holding section for detachably carrying a puncture instrument for protruding a puncture needle and a measuring instrument holding section for detachably carrying a measuring instrument for analyzing body fluid with a biosensor, the biosensor being attached to the measuring instrument and having a body fluid supply part to which body fluid is supplied. With use of the adaptor, the body fluid can be measured easily and speedily with the puncture instrument and the measuring instrument attached thereto, which are independent from each other. The present invention further provides a measuring instrument including a puncture instrument holding section.

Claims

1. An adaptor for body fluid measurement comprising:

a puncture instrument holding section for detachably carrying a puncture instrument for protruding a puncture needle; and

a measuring instrument holding section for detachably carrying a measuring instrument for analyzing body fluid with a biosensor, the biosensor being attached to the measuring instrument and having a body fluid supply part to which body fluid is supplied.

2. The adaptor in accordance with claim 1, wherein the puncture instrument holding section and the measuring instrument holding section are arranged to be adjacent to each other to carry the puncture instrument and the measuring instrument in such a manner that the puncture needle protruding from the puncture instrument carried by the puncture instrument holding section comes close to the body fluid supply part of the biosensor of the measuring instrument carried by the measuring instrument holding section.

3. The adaptor in accordance with claim 2, wherein the puncture instrument holding section and the measuring instrument holding section are configured such that an axis of the puncture needle of the puncture instrument carried by the puncture instrument holding section intersects with an axis of an inserting direction of the biosensor attached to the measuring instrument carried by the measuring instrument holding section.

4. The adaptor in accordance with claim 2, further comprising an adjustment part for adjusting an angle of the puncture instrument holding section with respect to the measuring instrument holding section.

5. The adaptor in accordance with claim 1, wherein the puncture instrument holding section includes an embrace part for embracing a barrel of the puncture instrument.

6. The adaptor in accordance with claim 5, wherein the embrace part comprises a cylinder provided with a slit, the cylinder being configured to have a diameter slightly smaller than a diameter of the barrel of the puncture instrument to embrace the barrel of the puncture instrument by an elastic force thereof.

7. The adaptor in accordance with claim 5, wherein the puncture instrument holding section has a concave portion or a convex portion to fit with a convex portion or a concave portion formed on the barrel of the puncture instrument.

8. A body fluid measuring instrument comprising a biosensor holding section for holding a biosensor having a body fluid supply part to which body fluid is supplied to analyze the body fluid supplied to the biosensor through the biosensor, wherein the body fluid measuring instrument has a puncture instrument holding section for detachably carrying a puncture instrument for protruding a puncture needle and the puncture instrument holding section is configured such that the puncture needle protruding from the puncture instrument carried by the puncture instrument holding section comes close to the body fluid supply part of the biosensor.

9. The body fluid measuring instrument in accordance with claim 8, wherein the puncture instrument holding section and the biosensor holding section are configured such that an axis of the puncture needle of the puncture instrument carried by the puncture instrument holding section intersects with an axis of an inserting direction of the biosensor attached to the biosensor holding section.

10. The body fluid measuring instrument attached with the puncture instrument in accordance with claim 8, wherein the puncture instrument holding section has an embrace part for embracing a barrel of the puncture instrument.

11. The body fluid measuring instrument attached with the puncture instrument in accordance with claim 8, wherein the embrace part comprises a cylinder provided with a slit, the cylinder being configured to have a diameter slightly smaller than a diameter of the barrel of the puncture instrument to embrace the barrel of the puncture instrument by an elastic force thereof.

12. The body fluid measuring instrument attached with the puncture instrument in accordance with claim 8, wherein the puncture instrument holding section has a concave portion or a convex portion to fit with a convex portion or a concave portion formed on the barrel of the puncture instrument.
