The present invention relates to a valve and a method for coupling the same. The valve is installed in a mechanism, which comprises a needle, a hub connected to the needle, and a connection part connected to the hub, so as to prevent fluid, filled in an apparatus for injecting the fluid into a living body, from being exposed to air. The connection part is coupled to an inner space of the hub, wherein the valve is installed in a dead space left in the inner space, except the portion to which the connection part is coupled. Thus, the present invention prevents fluid from flowing into the dead space by minimizing the volume of the dead space through the valve, and at the same time allows the fluid to flow through the valve. |
