Abstract: An autoinjector including a housing, in which can be mounted a syringe having a plunger, a barrel and needle at one end thereof through which medicament can be delivered to an injection site; a syringe support means capable of causing said syringe to move therewith along an axial path with respect to said housing; biasing means capable of biasing said syringe support means so that said needle is normally inside said housing, blocking means selectively moveable by a user from a first position in which rearward movement of the syringe along said axial path is substantially prevented, to a second position in which rearward movement of the syringe along said axial path relative to said housing is possible and said biasing means causes said needle to retract inside said housing.

Abstract: An autoinjector comprising an outer housing in which can be mounted a syringe for holding a volume of medicament, the syringe for holding medicament having a needle at one end thereof, a syringe holder for supporting the syringe in an axial position relative to the outer housing, and an intermediate housing at least part of which is located within said outer housing, characterised in that said intermediate housing is provided with a blocking means capable of abutting the syringe or the syringe holder so as to be capable of preventing forward axial movement of the syringe when a forward axial force is applied to said needle before actuation of the autoinjector to deliver an injection, but incapable of preventing forward axial movement of the syringe during actuation of the autoinjector to deliver an injection.

Abstract: An autoinjector comprising an outer housing in which is mounted a syringe comprising a barrel for holding a volume of medicament, a needle at one end of the barrel and a plunger axially-moveable in the barrel, the autoinjector further comprising an inner housing intermediate the outer housing and the syringe and an energy source in communication with said inner housing, wherein the inner housing is moveable by the energy source between three positions, namely a first position in which the inner housing is in communication with the barrel such that, in use, the plunger and barrel are moveable axially so as to move at least part of said needle out of the outer housing; a second position in which the inner housing is in communication with the plunger but not the barrel such that, in use, said plunger is moveable axially into said barrel so as to expel medicament through the needle; and a third position in which the inner housing is in communication with neither the plunger nor the barrel such that, in use,

Abstract: An autoinjector device for delivering a dose of medicament including a syringe including a needle wherein, prior to use of the device, the needle is substantially covered by a needle sheath (107). The autoinjector further includes a housing (112) in which said syringe is located, an outer packaging in which said housing is located, where the outer packaging comprising a front packaging (101) part and a rear packaging part. The autoinjector also includes needle sheath removing means (103) associated with said front packaging part (101), wherein, prior to use of the device, said front and rear packaging parts cooperate together to entirely enclose said housing, syringe and needle sheath, and wherein, upon axial separation of said front and rear packaging parts, said needle sheath removing means is capable of causing axial separation of said needle sheath from said needle so as to remove said needle sheath therefrom.

Abstract: A safety syringe assembly (10) adapted for use in an autoinjector comprising a syringe (12) and a first sleeve (22) that at least partially surrounds the syringe. The syringe has a barrel (14) for holding a volume of medicament, a needle (18) at one end of the barrel, and a plunger (20), axially moveable within the barrel. The syringe is axially moveable relative to the first sleeve between a first position, in which the needle is exposed, and a second position, in which the needle is surrounded by the first sleeve and is not exposed. The syringe is axially lockable with respect to the first sleeve when in the second position.
