The present Invention relates to a syringe, and more particularly,A device obtained by improving a conventional syringe comprising a Flow channel that includes an injection Needle, injectionIn order to share a part of flow duct injection except the injection Needle or to form a Flow Channel is completely independent of the flow DUCT INProjection, thereby facilitating the Suction of the medicine Liquid.The syringe comprises an injection Needle (10), a Cylinder (20) and is formed with a through Flow Injection that extends from the Cylinder (20) until the injection Needle (10),And also includes a means for Opening / closing (400) for selectively opening or Closing the flow duct injection； a Flow duct Suction cover formed from a Hollow pointed (100)(20) until the Cylinder and provided with a Hole (200) formed in any place of the injection Needle (10), a Connector to connect the injection Needle Cylinder (10) to (20),And the Cylinder (20) to establish Communication between the internal part and external part thereof； and a Valve means (300) to control the opening or closing of intermittently withSuction duct Flow by the Manipulation of a user.The syringe is configured so that a Flow duct Suction that is independent of the injection needle is formed in the conventional syringe to Gently Suction out meLiquid product, thereby maximizing user convenience and marketability of the product,In addition, the forced closure of the flow duct Suction following the Injection of the medicine Liquid.La presente invención se refiere a una jeringa, y más particularmente, a un aparato obtenido mejorando una jeringa convencional formada con un conducto de flujo de inyección que incluye una aguja de inyección, con el fin de compartir una parte de conducto de flujo de inyección excepto la aguja de inyección o para formar un conducto de flujo de succión completamente independiente del conducto de flujo de inyección, de ese modo además facilita la succión de un medicamento líquido.
