Component Separator

Abstract

The present invention relates to a component separator capable of guaranteeing the purity of a subject component such as isolated blood or stem cells while simplifying a process compared with a conventional technique, and preventing air contamination during a component separation process, the component separator comprising: a hollow main body having a communication pipe, through which a body fluid communicates, formed at one end portion, and a main body female screw part disposed at the other end portion; a plunger for varying a main body space while moving forward and backward inside the main body; and an operation member having a pressing tube having a pressing male screw part capable of being screwed with the main body female screw part, and a plunger coupling tube having a tube screw screwed with a plunger screw part at the lower part of the plunger by coming into contact with or retracting from the inside of the pressing tube.

1 . A component separator comprising:
 a hollow main body which includes a communication pipe formed at one end portion thereof to allow a flow of body fluids therethrough and a main body female screw part disposed at the other end portion;   a plunger which is installed inside of the main body to vary a main body space while moving forward and backward; and   an operation member which includes a pressing tube having a pressing male screw part to be screwed with the main body female screw part, and a plunger coupling tube having a tube screw to be screwed with a plunger screw part formed at a lower part of the plunger by slidably moving inside of the pressing tube.   
     
     
         2 . The component separator according to  claim 1 , wherein thread directions of the main body female screw part and the pressing male screw part are opposite to thread directions of the plunger screw part and the tube screw. 
     
     
         3 . The component separator according to  claim 1 , wherein the tube screw has an offset part formed at an end thereof without a thread. 
     
     
         4 . The component separator according to  claim 1 , wherein a tube protrusion stopper is formed at a lower side of the tube screw to limit a protrusion amount of the tube screw. 
     
     
         5 . The component separator according to  claim 1 , wherein a tube separation preventing cover is installed at a lower side of the pressing tube, and the plunger coupling tube has a tube separation stopper formed at a lower portion of an outer circumference thereof to limit a movement of the plunger coupling tube. 
     
     
         6 . The component separator according to  claim 5 , wherein a spring is installed between the tube separation stopper and the tube separation preventing cover to easily guide attaching and detaching of the tube screw with the plunger screw part. 
     
     
         7 . The component separator according to  claim 5 , wherein a spring is installed between a pressing tube protrusion formed on the pressing tube and a tube protrusion stopper of the plunger coupling tube to easily guide attaching and detaching of the tube screw with the plunger screw part.
