1. A medicament delivery device comprising:
a body;
a needle for injecting a medicament, the needle disposed at a distal end of the medicament delivery device;
a needle cover axially movable relative to the body between an extended position, in which a distal end of the needle cover is distal to a distal end of the needle, and a retracted position for dispensing the medicament from the medicament delivery device, wherein when the needle cover is in the retracted position the distal end of the needle is distal to the distal end of the needle cover; and
a carrier configured to support a syringe, wherein the carrier is disposed within the needle cover and comprises a deformable element, the deformable element being configured to change from a first configuration in which the deformable element is engaged with the needle cover to a second configuration in which the deformable element is not engaged with the needle cover,
wherein the deformable element is configured
to have a convex shape which protrudes from the carrier towards the needle cover when the deformable element is in the first configuration; and
to have a concave shape which curves away from the needle cover when the deformable element is in the second configuration,
wherein the carrier includes a recess configured to receive at least a part of the deformable element when the deformable element is the concave shape.
 
16. A medicament delivery device comprising:
a body;
a needle for injecting a medicament, the needle disposed at a distal end of the medicament delivery device;
a needle cover axially movable relative to the body between an extended position, in which a distal end of the needle cover is distal to a distal end of the needle, and a retracted position for dispensing the medicament from the medicament delivery device, wherein when the needle cover is in the retracted position the distal end of the needle is distal to the distal end of the needle cover; and
a carrier configured to support a syringe, wherein the carrier is disposed within the needle cover and comprises two or more deformable elements, the two or more deformable elements being configured to change from a first configuration in which each deformable element of the two or more deformable elements is engaged with the needle cover to a second configuration in which each deformable element of the two or more deformable elements is not engaged with the needle cover,
wherein each deformable element of the two or more deformable elements is configured
to have a convex shape which protrudes from the carrier towards the needle cover when each deformable element of the two or more deformable elements is in the first configuration; and
to have a concave shape which curves away from the needle cover when each deformable element of the two or more deformable elements is in the second configuration,
wherein the carrier includes a recess configured to receive at least a part of each deformable element of the two or more deformable elements when each deformable element of the two or more deformable elements is the concave shape.
 
18. A medicament delivery device comprising:
a body;
a needle for injecting a medicament, the needle disposed at a distal end of the medicament delivery device;
a needle cover configured to be moved in a proximal direction into the body of the medicament delivery device to expose a distal end of the needle from a distal end of the needle cover; and
a syringe carrier disposed within the needle cover and comprising a deformable element,
wherein the deformable element is configured such that
prior to a movement of the needle cover relative to the body of the medicament delivery device, the deformable element has a first configuration in which the deformable element is engaged with the needle cover;
during an initial portion of the movement of the needle cover relative to the body, the deformable element is forced to deform into a second configuration by the movement of the needle cover such that the deformable element is not engaged with the needle cover; and
for a remainder of the movement of the needle cover relative to the body, the deformable element remains in the second configuration,
wherein the deformable element is configured
to have a convex shape which protrudes from the syringe carrier towards the needle cover when the deformable element is in the first configuration; and
to have a concave shape which curves away from the needle cover when the deformable element is in the second configuration,
wherein the syringe carrier includes a recess configured to receive at least a part of the deformable element when the deformable element is the concave shape.
