Abstract
Provided is a centrifugal separation container for separating a material from tissue and body fluids by using a centrifugal force, including: a first container; a second container; a first piston positioned in the inside of the first container and configured to be movable up and down in the inside of the first container; an elastic body positioned below the first piston in the inside of the first container and configured to elastically bias the first piston upward; a first connecting duct having one end connected to the first container and the other end connected to the second container; and a first control valve operating by a centrifugal force and configured to open and close the first connecting duct.
Claims14
A centrifugal separation container for separating a material from tissue and body fluids using a centrifugal force, comprising:
- a first container;
- a second container;
- a first piston positioned in the inside of the first container and configured to be movable up and down in the inside of the first container;
- an elastic body positioned below the first piston in the inside of the first container and configured to elastically bias the first piston upward;
- a first connecting duct having one end connected to the first container and the other end connected to the second container;
- and
- a first control valve operating by a centrifugal force and configured to open and close the first connecting duct.
A method for moving substances inside centrifugal separation container, the centrifugal separation container comprising:
- a first container having a first space;
- a first piston positioned in the first space, dividing the first space to an upper space and a lower space, and configured to be movable up and down in the inside of the first container;
- a filling container having a filling space in which a movement target material is filled;
- a second piston positioned in the inside of the filling container, dividing the filling space into an upper space and a lower space, and configured to be movable up and down in the inside of the filling container;
- and
- a connecting duct connecting the first container to the filling container and having one end connected to the lower space below the second piston in the filling container and the other end connected to the upper space above the first piston in the first container,
- wherein a centrifugal force is applied to move the second piston and the first piston downward, and positive pressure generated by the second piston is combined with negative pressure generated by the first piston so that a material filled below the second piston in the filling container moves to the upper space above the first piston in the first container through the connecting duct.
