Abstract
The present disclosure relates to an injection device. The injection device comprises a cap and a body for holding a syringe that has a needle at one end. The cap is removably attached to the body and has a needle shield to receive the needle. The injection device further comprises an actuator that is slidable relative to the body in the longitudinal direction of the body to urge the needle shield away from the body.
Claims16
An injection device comprising:
- a body for holding a syringe that has a needle at one end;
- a cap that is removably attached to the body and has a needle shield received within the cap to receive the needle;
- and
- an actuator that is slidable relative to the body in a longitudinal direction of the body to urge the needle shield away from the body,
- wherein at least a part of the actuator extends out of the body when the actuator is slid relative to the body to urge the needle shield away from the body, and wherein the part of the actuator which extends out of the body to urge the needle shield away from the body comprises a needle sleeve moveable relative to the body between an extended position, to shield the needle when the syringe is held in the body, and a retracted position,
- wherein in the extended position, an end of the needle sleeve extends axially past the needle, and in the retracted position, the needle extends axially past the end of the needle sleeve, and
- wherein the actuator is configured such that when the actuator is slid relative to the body to urge the needle shield away from the body, the needle sleeve moves to the extended position.
A method of removing a cap from a body of an injection device, wherein the body holds a syringe that has a needle at one end and wherein the cap is removably attached to the body and has a needle shield received within the cap to receive the needle, the method comprising:
- sliding an actuator relative to the body, in a longitudinal direction of the body, such that at least a part of the actuator extends out of the body, to urge the needle shield away from the body, wherein the part of the actuator which extends out of the body to urge the needle shield away from the body comprises a needle sleeve moveable relative to the body between an extended position, to shield the needle, and a retracted position,
- wherein in the extended position, an end of the needle sleeve extends axially past the needle, and in the retracted position, the needle extends axially past the end of the needle sleeve, and
- wherein sliding the actuator relative to the body to urge the needle shield away from the body moves the needle sleeve to the extended position.
