Abstract
A push button safety injector includes a housing having a proximal end, a distal end spaced from the proximal end, and a longitudinal axis. An injection ram is positioned along the longitudinal axis and configured to actuate a fluid chamber. The injection ram is biased toward the distal end in an initial position. A sliding member is configured to retain the injection ram in the initial position. A safety member confines radial movement of the sliding member in the initial position and allows radial movement of the sliding member in an armed position. A button is moveable between an initial extended position and a depressed position. The button is engagable with the sliding member and configured to move the sliding member radially in the armed position. The sliding member releases the injection ram when the button is in the depressed position.
