PURPOSE: A catheter for preventing reverse flowing of blood is provided, which can prevent patient's blood from flowing reversely even though a connection tip for supplying sap or blood is reinstalled in a catheter hub. CONSTITUTION: A catheter for preventing reverse flowing of blood comprises: a catheter hub(20); a catheter tube(30) expanded to the front end of the catheter hub at the regular length; a cannula(40) which passes the catheter tube and is inserted into the blood vessel; and a blood blocking member which prevents blood flowing reversely inside the catheter hub. The blood blood blocking member includes: a stem portion(60) in which a through-path is formed in the center length direction; a packing member(70) in which a split is formed in the center; and a lid part(80) covering the stem portion.
