is provided a medicament delivery device comprising: a main body arranged to receive a medicament cartridge; a needle for delivery of medicament from the medicament cartridge; a needle cover moveable between an initial position, in which the needle cover covers the needle, and an activated position for dispensing medicament from the medicament delivery device, wherein in the activated position the needle protrudes from a distal end of the needle cover; an outer frame, moveable relative to the main body between an extended position in which the outer frame extends past a distal end of the needle, and a retracted position in which the outer frame is moved towards the main body; an attachment element comprising an adhesive region for attaching the medicament delivery device to a surface when the needle cover is in the activated position, the attachment element comprising a protective barrier covering the adhesive region. ## Claims ### Claim 1 A medicament delivery device comprising: a main body arranged to receive a medicament cartridge; a needle for delivery of medicament from the medicament cartridge; a needle cover moveable between an initial position, in which the needle cover covers the needle, and an activated position for dispensing medicament from the medicament delivery device, wherein in the activated position the needle protrudes from a distal end of the needle cover; an outer frame, moveable relative to the main body between an extended position in which the outer frame extends past a distal end of the needle, and a retracted position in which the outer frame is moved towards the main body; and an attachment element comprising an adhesive region for attaching the medicament delivery device to a surface when the needle cover is in the activated position, the attachment element comprising a protective barrier covering the adhesive region, wherein the protective barrier is coupled to the outer frame and is removed from the attachment element to expose the adhesive region as the outer frame is moved towards the retracted position, and wherein the protective barrier is configured to pull the surface in a direction away from an injection site as the protective barrier is removed from the attachment element. ### Claim 2 (depends on 1) The medicament delivery device according to claim 1, wherein the protective barrier is removed from the attachment element, and the needle cover is moved from the initial position to the activated position, with a single action of providing a force on the medicament delivery device in a distal direction. ### Claim 3 (depends on 1) The medicament delivery device according to claim 1, wherein the protective barrier comprises a folded portion releasably secured to the attachment element. ### Claim 4 (depends on 3) The medicament delivery device according to claim 3, wherein the folded portion comprises a double layer of the protective barrier covering at least a portion of the attachment element. ### Claim 5 (depends on 3) The medicament delivery device according to claim 3, wherein a second end of the protective barrier is releasably secured to the attachment element, and the second end is folded towards the attachment element to form the folded portion. ### Claim 6 (depends on 1) The medicament delivery device according to claim 1, wherein the outer frame is external to the main body in both the extended position and the retracted position. ### Claim 7 (depends on 1) The medicament delivery device according to claim 1, wherein an adhesive force from the attachment element is greater than a spring force of the needle cover. ### Claim 8 (depends on 1) The medicament delivery device according to claim 1, wherein when the needle cover is in the initial position, the attachment element is positioned set back in a proximal direction from a distal most end of the medicament delivery device. ### Claim 9 (depends on 1) The medicament delivery device according to claim 1, wherein the outer frame is pivotable relative to the main body to move between the extended position and the retracted position. ### Claim 10 (depends on 9) The medicament delivery device according to claim 9, wherein the outer frame comprises a removal arm, wherein a first end of the removal arm is pivotally coupled to the main body, and a second end of the removal arm is moveable relative to an internal face of a contact surface of the outer frame. ### Claim 11 (depends on 10) The medicament delivery device according to claim 10, wherein as the outer frame moves from the extended position to the retracted position, the second end of the removal arm is pushed along the internal face of the outer frame to pull the protective barrier away from the attachment element. ### Claim 12 (depends on 9) The medicament delivery device according to claim 9, wherein the protective barrier is configured to be pulled through an aperture in a contact surface of the outer frame. ### Claim 13 (depends on 1) The medicament delivery device according to claim 1, wherein the outer frame comprises a releasable mechanism to automatically retract the protective barrier from the attachment element, wherein the releasable mechanism is activated as the outer frame is moved towards the main body. ### Claim 14 (depends on 13) The medicament delivery device according to claim 13, wherein the releasable mechanism comprises at least one biased roller, and a first end of the protective barrier is wound around the at least one biased roller, and a second end of the protective barrier is releasably attached to the attachment element. ### Claim 15 (depends on 1) The medicament delivery device according to claim 1, wherein the outer frame comprises at least one tension member to hold the protective barrier in tension as it is removed from the attachment element. ### Claim 16 (depends on 1) The medicament delivery device according to claim 1, wherein the protective barrier comprises two components and the surface is pulled in opposing directions by each part of the protective barrier as the protective barrier is removed from the attachment element. ### Claim 17 (depends on 1) The medicament delivery device according to claim 1, wherein the adhesive region holds the surface taut until the medicament delivery device is removed from the surface. ### Claim 18 (depends on 1) The medicament delivery device according to claim 1, comprising a container of medicament. ### Claim 19 A method of operating a medicament delivery device, the method comprising: moving an outer frame relative to a main body of the medicament delivery device from an extended position, in which the outer frame extends past a distal end of a needle, to a retracted position, in which the outer frame is moved towards the main body; exposing an adhesive region of an attachment element by removing a protective barrier covering the adhesive region, wherein the protective barrier is coupled to the outer frame of the medicament delivery device and is removed as the outer frame is moved towards the retracted position; and adhering the exposed adhesive region of the attachment element to a surface for preparation of delivery of a medicament, wherein the protective barrier is configured to pull the surface in a direction away from an injection site as the protective barrier is removed from the attachment element.
