An injection device for use with a syringe having a syringe body provided with radially extending wings at a distal end thereof, a needle coupled to a proximal end of the syringe body, and a plunger which can be moved through the syringe body to eject medication from the syringe through the needle, the injection device comprising: a housing (30,31) defining an inner space for holding a syringe and facilitating movement of the syringe from a first position in which the needle is contained fully within the housing and a second position in which the needle projects from the housing; a support tube sitting within the housing and within which a syringe is supported, the support tube comprising a collar around its distal end; a coil spring supported between said collar and the housing, wherein the wings of the syringe body act on the collar to compress the compression spring and said second position being defined by full compression of the coil spring; a drive member located within said inner space so that in use the drive member can engage the plunger of a syringe held within the housing; a force applicator located within said inner space for providing a force to the drive member which in turn acts on the plunger so as to move the syringe from said first to said second position and thereafter to move the plunger through the syringe body; a trigger mechanism (33,35) for retaining the force applicator and the drive member in a cocked configuration and, upon activation, for releasing the force applicator and the drive member; and a pneumatic damper (47,39) for damping the kinetic energy imparted by the drive member to the syringe plunger during all or a part of the movement of the syringe from said first to said second position characterised in that said pneumatic damper comprises a piston having a piston head in engagement with said drive member and a cylinder within which the piston is mounted, said piston and cylinder defining a chamber and one of the piston and cylinder defining a passage for allowing fluid to flow into and out of said chamber, the piston and cylinder being further configured such that movement of the piston outwardly with respect to the cylinder beyond a certain point, defined by said second position, creates an additional air flow path into said chamber, reducing or eliminating damping of the drive member. a housing (30,31) defining an inner space for holding a syringe and facilitating movement of the syringe from a first position in which the needle is contained fully within the housing and a second position in which the needle projects from the housing; a support tube sitting within the housing and within which a syringe is supported, the support tube comprising a collar around its distal end; a coil spring supported between said collar and the housing, wherein the wings of the syringe body act on the collar to compress the compression spring and said second position being defined by full compression of the coil spring; a drive member located within said inner space so that in use the drive member can engage the plunger of a syringe held within the housing; a force applicator located within said inner space for providing a force to the drive member which in turn acts on the plunger so as to move the syringe from said first to said second position and thereafter to move the plunger through the syringe body; a trigger mechanism (33,35) for retaining the force applicator and the drive member in a cocked configuration and, upon activation, for releasing the force applicator and the drive member; and a pneumatic damper (47,39) for damping the kinetic energy imparted by the drive member to the syringe plunger during all or a part of the movement of the syringe from said first to said second position characterised in that said pneumatic damper comprises a piston having a piston head in engagement with said drive member and a cylinder within which the piston is mounted, said piston and cylinder defining a chamber and one of the piston and cylinder defining a passage for allowing fluid to flow into and out of said chamber, the piston and cylinder being further configured such that movement of the piston outwardly with respect to the cylinder beyond a certain point, defined by said second position, creates an additional air flow path into said chamber, reducing or eliminating damping of the drive member. said pneumatic damper comprises a piston having a piston head in engagement with said drive member and a cylinder within which the piston is mounted, said piston and cylinder defining a chamber and one of the piston and cylinder defining a passage for allowing fluid to flow into and out of said chamber, the piston and cylinder being further configured such that movement of the piston outwardly with respect to the cylinder beyond a certain point, defined by said second position, creates an additional air flow path into said chamber, reducing or eliminating damping of the drive member.
