Abstract
A liquid feeding method for feeding liquid in a minute flow path is provided. The minute flow path includes flow paths 43a, 43c, 43d connected to each other directly at respective first ends. The liquid feeding direction of blood S in the minute flow path is controlled by creating a high-pressure state at a second end of the flow path 43a located across the blood S, while creating a low-pressure state or a closed state at a second end of the flow paths 43d, 43c.
Claims8
A liquid feeding method for feeding liquid in a minute flow path including at least three flow paths having respective first ends connected to each other directly or indirectly via a connection flow path, the method comprising:
- introducing the liquid;
- creating a high-pressure state at a second end of at least one of said at least three flow paths;
- and creating a low-pressure state or a closed state at second ends of remaining flow paths, thereby controlling a liquid feeding direction of the liquid in the minute flow path.
A cartridge to be mounted to a separate apparatus, the cartridge comprising a minute flow path for feeding liquid;
- wherein the minute flow path includes at least three flow paths having respective first ends connected to each other directly or indirectly via a connection flow path,
- wherein each of the flow paths has a second end connected to a hole.
