| abstract |
The present invention relates to a valve and a method of coupling the same to a device including a needle, a hub connected to the needle, and a connection part connected to the hub, so that the fluid filled inside the device for injecting fluid into a living body is not exposed to air. In the installed valve, a connection portion is coupled to an inner space of the hub, and a valve is provided in a remaining space other than a portion where the connection portion is coupled in the inner space, so that the volume of the dead space is minimized through the valve, There is an effect that the fluid flows through the valve while preventing the inflow of the fluid. |
