Definitions
- the present invention relates to a component separation device for separating respective components of a fluid, such as blood or emulsion, in which a liquid component and a solid component are mixed, a method for producing the same, and a component separation device using the device. It relates to a separation method.
- Fluids in which a plurality of solid components are mixed include, for example, river water, seawater, blood, and the like. These are a mixture of liquid and solid components, and solid components such as sand, bacteria, and blood cells exist as solids without melting into the liquid components due to precipitation or dispersion.
- a method for separating these components for example, an apparatus for separating blood cells from blood will be described.
- blood is collected in a whole blood state composed of plasma, which is a liquid component, blood cells, which are solid components, and other components.
- plasma which is a liquid component
- blood cells which are solid components
- other components the only component required for a blood test is the blood cell portion or, conversely, only the plasma portion.
- the plasma component is extracted by extracting the supernatant, and the blood cell component is extracted from the precipitate. Thereafter, each of the separated components is subjected to a predetermined measurement in an inspection process.
- the conventional method using a centrifuge has the following problems. In other words, it is necessary to have a certain amount of whole blood in a test tube, for example, a sample of several tens It is important. Therefore, this method requires a small amount of sample! In some cases, it is difficult to separate the liquid component and the solid component.
- a method for separating solid components from a small amount of sample using a filter is described in "Integrated vertical screen microinter system using inclined SU—8 structure.” (Yong-Kyu Yoon, MEMS2003, Kyoto, pp. 227-230 IEEE Issued). Blood cells of a predetermined size or more are filtered by a porous filter, and blood plasma components and blood cells are separated and taken out.
- the size and number of filter holes affect the separation characteristics. Therefore, it is necessary to design the filter optimally according to the component to be separated. For example, a mesh-shaped filter can be created with high precision by exposing a photosensitive resist in three dimensions, and the size and number of filter holes can be created with high accuracy.
- the size of particles of a solid component passing therethrough varies depending on the pressure at which a fluid or a powder mixed with a plurality of components passes through the filter.
