Abstract
A medicament delivery device has a syringe, a housing, a needle shield, a biasing member and one or more blocking members. The needle shield is biased axially forwardly by the biasing member so as to selectively cover a needle of the syringe. However, the biasing member is prevented from biasing the needle shield axially forwardly until a radial movement of the blocking members has occurred, which is precipitated by a forward axial movement of the syringe. Consequently, the forward movement of the syringe releases the needle shield to automatically make safe the device.
