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.
Claims11
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;
- wherein the first control valve comprises a first valve configured as an initial close valve that is closed before a centrifugal force is applied and that is opened after a centrifugal force is applied,
- wherein the first connecting duct comprises a first duct connected to the first container, a second duct connected to the second container, and a vertical flow path connecting the first duct to the second duct and extending vertically, and
- wherein the first control valve comprises a weight body having a predetermined weight and an elastic ring disposed around the weight body, the first control valve closing the vertical flow path before a centrifugal force is applied as the weight body is friction-fitted in the vertical flow path, and after a centrifugal force is applied, escaping from the vertical flow path so that an open state is maintained between the first duct and the second duct, a valve operating hole is formed above the first container to extend vertically, the valve operating hole being located above the vertical flow path, and an operating beam is provided on the weight body to pass the valve operating hole to be exposed upward.
A method for moving substances inside a centrifugal separation container, the method comprising:
- providing the 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;
- and
- moving a material filled below the second piston in the filling container to the upper space above the first piston in the first container through the connecting duct by applying a centrifugal force to move the second piston and the first piston downward, and to combine positive pressure generated by the second piston with negative pressure generated by the first piston.
