Abstract

A needle retraction mechanism includes a hollow handle defining a cavity, a tab associated with the handle, a needle hub assembly movably disposed in the handle, a biasing mechanism to move the needle hub assembly from an extended position to a retracted position and an arm to hold needle hub assembly in the extended position against the bias of the biasing mechanism. The tab and arm are configured such that downward movement of the tab engages the arm to allow the needle hub to move to the proximal end of the handle. In addition, the tab and arm are configured so that at least a portion of the downward movement of the tab is translated into a proximally directed axial movement of the needle hub. This facilitates movement of the needle hub and overcomes any static friction between the needle hub and the inner wall of the handle tending to hold the needle hub in the extended position.
