Claim 0:
1. A needle actuator assembly for a drug delivery system, the needle actuator assembly comprising:
a housing;
a needle having a retracted position and an extended position;
a needle actuator body received within the housing and configured to move from a pre-use position where the needle is in the retracted position to a use position where the needle is in the extended position and to a post-use position where the needle is in the retracted position, the needle actuator having a button contact surface; and
an actuator button received by the housing, the actuator button moveable relative to the housing between a first position and a second position, the actuator button including a lockout arm,
wherein movement of the actuator button from the first position to the second position moves the needle actuator body from the pre-use position to the use position,
wherein the lockout arm of the actuator button engages and is disposed below the button contact surface of the needle actuator body when the needle actuator body is in the use position to restrict movement of the actuator button from the second position to the first position, and
wherein, when the needle actuator body is in the pre-use position, the lockout arm of the actuator button is disposed above the button contact surface of the needle actuator body in order to prevent the needle actuator body from moving upward.
