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 formed from the Cylinder (20) until the injection Needle (10).The syringe also includes an Opening \/ closing (400) for selectively opening or Closing the flow duct injection and a Flow duct Suction cover formed from a Sharp HUECA (100) to the Cylinder (20) and provided with a Hole formed in any place of the injection Needle (10),A Connector (500) to connect the injection Needle Cylinder (10) to (20),And the Cylinder (20) for establishing Communication between an Interior and an exterior of the same and a Unidirectional valve (300) to control the opening or intermittentlyTo close the hole.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.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. La jeringa incluye una aguja de inyección (10), un cilindro (20) y es formado con un conducto de flujo de inyección formado desde el cilindro (20) hasta la aguja
