Abstract: An injection simulation device and methods thereof is provided. The device includes an elongated handle having a first end and a second end, wherein the elongated handle has a sidewall with an interior surface defining an interior space, wherein the interior space is completely empty. An end portion is integral with the sidewall and positioned at the first end of the elongated handle, the end portion enclosing the first end of the elongated handle. A first attachment structure is integral with the second end of the elongated handle. A hollow needle is connected to a hub having an end point, wherein the end point has a second attachment structure engagable with the first attachment structure to connect the hub to the second end of the elongated handle.
