Abstract

A circuit board for body fluid collection is provided with an insulating layer, a puncture needle supported by the insulating layer and a conductor pattern that integrally has an electrode which is supported by the insulating layer and brings body fluid collected by puncture of the puncture needle into contact with the board, a terminal connected to a device measuring a component of body fluid and wiring for electrically connecting the electrode and the terminal.

Claims

1. A circuit board for body fluid correction comprising:

an insulating layer;

a puncture needle supported on the insulating layer; and

a conductive pattern supported on the insulating layer, and integrally including;

an electrode to be brought into contact with a body fluid collected by puncture with the puncture needle;

a terminal to be connected to a device for measuring a component of the body fluid; and

a wire electrically connecting the electrode and the terminal.

2. The circuit board for body fluid collection according to claim 1, wherein a stopper for restricting further puncture with the puncture needle is provided on an upstream side of the puncture needle in a puncture direction thereof.

3. The circuit board for body fluid collection according to claim 2, wherein the stopper is provided at a position spaced apart from a tip of the puncture needle by 0.3 to 2.0 mm in the puncture direction of the puncture needle.

4. The circuit board for body fluid collection according to claim 1, wherein the insulating layer is provided with a dam that is disposed around the electrode in order to prevent leakage of the body fluid from the electrode.
