    摘要： A combination cantilever push tab and finger rest is associated with the needle shield and extends distally from the distal end of the needle shield. The cantilever push tab and finger rest includes a cantilever portion that extends distally from the needle shield, preferably from an exterior surface of the needle shield, and an upstanding tab portion at the distal end of the cantilever portion. This configuration causes the upstanding tab to extend over the proximal portion of the catheter adapter and allows a clinician to insert a catheter using virtually any clinically acceptable technique for inserting a catheter into a patient.

    摘要： 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.

    摘要： A needle retraction mechanism includes a hollow handle defining a cavity, 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 a latch to hold needle hub assembly in the extended position against the bias of the biasing mechanism. The needle hub assembly includes a flexible stopper at its proximal end that creates an air tight seal with the inner wall of the handle. This allows a vacuum to be created between the proximal end of the handle and the flexible stopper when the needle hub is moved from the retracted position to the extended position. The configuration of the flexible stopper allows it to change the amount of frictional force created between the inner wall of the handle and the flexible stopper when the device is at different elevations. At high elevations less frictional force exists between the inner wall of the handle and the flexible stopper while at low elevations greater frictional force exists between the inner wall of the handle and the flexible stopper.
