First, the area of the reverse side of cover 23 (the surface pasted to the spacer) corresponding to “the inner surface of supply channel 25” is preferably subjected to hydrophilicity treatment to make blood 13 smoothly flow into supply channel 25 by capillary action. Further, the area of the reverse side of cover 23 corresponding to “the upper side of storing part 24” is preferably less hydrophilic than the area of the reverse side of cover 23 corresponding to the inner surface of supply channel 25 to make blood 13 more smoothly flow into supply channel 25 at a constant speed. If blood 13 flows into supply channel 25 at a constant speed and reaches detecting section 27, the melting behavior of reagent 10 exhibits no variation, and the components of blood 13 can be measured correctly.
The surface of cover 23 (the reverse side of the surface pasted to the spacer) is preferably subjected to water-repellency treatment to prevent the blood in storing part 24 from flowing out more than necessary from air hole 26 or a hole in cover 23 (for example, puncturing hole 36 by puncturing needle 32 or hole 23 a in the cover). Further, the area of the reverse side of cover 23 corresponding to “the upper side of storing part 24” is preferably less water-repellent than the surface of cover 23 to prevent the blood in storing part 24 from flowing out, more effectively. By preventing blood from flowing out, it is possible to reduce the amount of sampled blood and alleviate the load on the patient.
In the surface of substrate 21, which abuts on the skin, at least the periphery of hole 21 a is preferably water-repellent, and the whole surface may be water-repellent. The term “water-repellency” preferably refers to a state where the surface free energy is less than 43 mN/m. When the surface of substrate 21, which abuts on the skin is water-repellent, when the skin is punctured with puncturing needle 32 the blood flowing out can be brought to storing part 24 more easily.
Further, an electrode system arranged in the blood sensor includes at least a “working electrode” and a “counter electrode.” The “working electrode” refers to an electrode for measuring blood components, and the “counter electrode” refers to a counterpart electrode of the working electrode. Further, the electrode system arranged in the blood sensor preferably includes a detecting electrode. The “detecting electrode” refers to an electrode for detecting whether blood is supplied to the detecting section. Still further, the electrode system may include an Hct electrode, which refers to an electrode for measuring the hematocrit level of blood.
FIG. 11 to FIG. 15 show examples of combination of blood sensor 20 integrated with holder 80 having attaching guide 81 that prevents a blood sensor from being led to certain undesirable positions and attaching part 90 of the blood test apparatus to which blood sensor 20 is attached. In this case, a “certain undesirable position” refers to a position where the connectors of the blood test apparatus are placed at the boundaries between the electrodes (such as connection terminals and a dummy electrode) formed in blood sensor 20, because, if the connectors of the blood test apparatus contact with the boundaries between the electrodes of blood sensor 20, measurement is not possible.
