Abstract
A blood analyzing apparatus is provided, which includes a microcapillary fabricated on a substrate by a micromanufacturing technique and used for sampling, filtering, separating, and moving blood and a detector so as to conduct a process from sampling blood to analyzing it using the substrate. A blood analyzing method is also provided for conducting a process from sampling blood to analyzing it by using the blood analyzing apparatus.
Claims8
A method of sampling, filtering, separating and analyzing blood in an apparatus, said apparatus comprising, in one or a plurality of substrates;
- sampling means for sampling blood from a living body;
- at least one of filtering means and separating means, the filtering means being for filtering at least the sampled blood to obtain blood plasma, the separating means being for separating serum from the blood;
- analyzing means for analyzing a substance in the blood;
- flow path means for interconnecting the sampling means, the filtering means, the separating means and the analyzing means;
- moving means for moving components of the blood present in the sampling means, the filtering means, the separating means, the analyzing means and the flow path means;
- outputting means for taking out information from the analyzing means;
- and
- control means for controlling an operation of at least one of the sampling means, the filtering means, the separating means, the analyzing means, the moving means and the outputting means;
- wherein said substrate further comprises holding means for holding the blood components in the substrate, and if the plurality of the substrates are present, these substrates are integrally constituted.
A blood analyzing apparatus comprising, in one or a plurality of substrates:
- sampling means for sampling blood from a living body;
- at least one of filtering means and separating means, the filtering means being for filtering at least the sampled blood to obtain blood plasma, the separating means being for separating serum from the blood;
- analyzing means for analyzing a substance in the blood;
- flow path means for interconnecting the sampling means, the filtering means, the separating means and the analyzing means;
- moving means for moving components of the blood present in the sampling means, the filtering means, the separating means, the analyzing means and the flow path means;
- outputting means for taking out information from the analyzing means;
- and
- control means for controlling an operation of at least one of the sampling means, the filtering means, the separating means, the analyzing means, the moving means and the outputting means;
- wherein the substrate further comprises holding means for holding the blood components in the substrate, and if the plurality of the substrates are present, these substrates are integrally constituted.
An apparatus in which:
- MPC polymer (2-methacryloyloxyethylphosphorylcholine) having a concentration of from 0.25 wt % to 1.0 wt % is applied onto at least an inner wall of a microcapillary, which is constituted of a groove-shaped structure having a width of from 10 μm to 150 μm and a depth of from 10 μm and 150 μm, and a cap for holding a material including at least a liquid in a groove of the groove-shaped structure.
