Abstract
A needle actuator assembly for a drug delivery system includes a housing, a needle having retracted and extended positions, 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, with the needle actuator having a button contact surface, and an actuator button received by the housing.
Claims20
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 causes the actuator button to contact and move the needle actuator body to release the needle actuator body and allow movement of the needle actuator body from the pre-use position to the use position, and
- wherein the lockout arm of the actuator button engages 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.
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;
- 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 moveable relative to the housing from a first axial position to a second axial position spaced from the first axial position, the actuator button restricted from movement from the first position to the second position when the actuator button is in the first axial position,
- wherein movement of the actuator button from the first position to the second position causes the actuator button to contact and move the needle actuator body to release the needle actuator body and allow movement of the needle actuator body from the pre-use position to the use position.
