Blood analysis device and blood analysis system using the same
A blood analysis device wherein a carrying part blood attached thereto can be localized to thereby facilitate handling after using. When incorporating blood collected from the punctured skin, the blood is held in a skin-puncturing device or the like so that an uncontaminated holding area can be enlarged and the degree of freedom in handling can be increased. A blood analysis device which comprises a plate type device body having a blood collection port for incorporating blood and a ventilation hole formed at a certain distance apart in a face and a passage located inside for connecting the blood collection port to the ventilation hole, and a blood analysis section located within the passage for analyzing the blood having been incorporated via the blood collection port.
1. A blood analysis apparatus comprising:
a casing having a puncturing opening, the casing mounted internally of the blood analysis apparatus with a blood analysis device;
the blood analysis device comprises a device body having a first plate, a second plate and a third plate which are stacked in this order in a stacking direction,
the first plate has a blood collecting hole that receives blood and a ventilation hole, which are spaced apart from each other on a same plane and which penetrate the first plate in the stacking direction,
the second plate has an opening comprising a passage that communicates with the blood collecting hole and the ventilation hole, and a blood analyzer provided in the passage, the blood analyzer analyzing the blood received through the blood collecting hole, and
the third plate has an optically transmissive portion which is aligned with the blood collecting hole and through which laser light is passed to puncture a skin arranged in the blood collecting hole, the third plate having no hole communicating with the passage,
the casing is configured to have the blood analysis device mounted in the casing such that the blood collecting hole is aligned with the puncturing opening of the casing, and such that the first plate faces the skin and the third plate faces the puncturing section of the blood analysis apparatus, and
a puncturing section configured to puncture the skin with laser light, the puncturing section mounted in the casing such that the laser light of the puncturing section is aligned with the puncturing opening and blood collecting hole such that the laser light punctures the skin.
2. The blood analysis apparatus according to claim 1 , further comprising a negative pressure creator that creates a negative pressure in the blood collecting hole of the blood analysis device that is mounted internally within the casing.
3. The blood analysis apparatus according to claim 1 , said optically transmissive portion extends in a plane parallel to a plane of the first plate.
4. The blood analysis apparatus according to claim 1 , said optically transmissive portion extends in a plane substantially perpendicular to the stacking order of said first, second and third plate.
