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 shuttle supporting the needle, the needle shuttle being movable along a vertical axis between the retracted position where the needle is positioned within the housing and the extended position where at least a portion of the needle extends out of the housing, wherein, when the needle shuttle moves between the retracted position and the extended position, the needle is constrained to move only along the vertical axis;
- 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 body having a button contact surface, wherein the needle actuator body comprises at least one guide surface and the needle shuttle comprises at least two cam surfaces;
- 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 the needle shuttle is configured to move between the retracted position and the extended position through engagement between at least one guide surface of the needle actuator and the at least two cam surfaces of the needle shuttle.

- 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, 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, 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, and
- wherein the needle shuttle is configured to move between the retracted position and the extended position through engagement between at least one guide surface of the needle actuator and the at least two cam surfaces of the needle shuttle.
