Abstract:
1. Apparatus for facilitating removal of a sheath from a pre-filled syringe having a barrel and a needle, the sheath providing a sterile cover for the needle, the apparatus comprising: a housing for at least partially enclosing the syringe barrel and defining an injection end with an aperture configured to allow the sheath of an enclosed syringe to protrude therethrough; a syringe barrel mount for retaining the syringe in the housing and being slidable axially within the housing between positions towards and away from the injection end of the housing such that the syringe and the syringe barrel mount move together; a biasing mechanism for biasing the mount away from the injection end of the housing; and a latching mechanism that latches said mount in a latched position to prevent sliding of the mount away from the injection end of the housing, the latching mechanism being releasable from the latched position by sliding of the mount towards the injection end; the latching mechanism being arranged such that when the latching mechanism is in the latched position the sheath of the syringe is exposed through the aperture, and the biasing mechanism being arranged such that removal of the sheath will cause the mount to slide towards the injection end, and such that when the latching mechanism is released the biasing mechanism urges the mount to a position where the needle of the syringe is retracted within the injection end of the housing.
