摘要： An injection device 110 is described having a housing 112 that receives a syringe 114. The syringe 114 is biased by a return spring 126 from an extended position in which the needle 118 extends from the housing 112 through an exit aperture 128 to a retracted position in which it does not. A drive spring 130 acts via a drive to advance the syringe 114 from its retracted position to its extended position and discharge its contents through the needle 118 and a return spring 126, brought into play when the drive has reached a nominal return position, restores the syringe 114 to its retracted position. A releasable locking mechanism retains the syringe 114 in its retracted position. A sleeve 119 projects from the exit aperture 128 and can be depressed to release the locking mechanism. A trigger 300 has a rest position, in which it engages the drive, retaining it in a position corresponding to the retracted position of the syringe 114, and a depressed position, in which it no longer causes the drive to be so retained. The sleeve 119 normally locks the trigger 300 in its rest position. However, depression of the sleeve 119 into the exit aperture 128, allows the trigger to be depressed. Thereafter, the trigger 300 is retained in its active position.

摘要： The present invention concerns an injection device with a housing adapted to receive a syringe having a discharge nozzle, the housing having an indicator opening. There is a trigger and a forward drive arranged to act upon the syringe on actuation of the trigger to advance the syringe from a retracted position to an extended position thereby discharging the contents of the syringe through the discharge nozzle. A support member is in contacting juxtaposition with the housing and a return drive is supported by the support member and arranged to act upon the syringe after the contents of the syringe has been discharged so that the syringe can be withdrawn from the extended position to the retracted position. Advantageously, the support member is arranged in the housing so that the second drive does not obscure an inspection of the contents of the syringe through the indicator opening. Hence, it can be clearly determined whether the contents of the syringe have been expelled from the syringe.

摘要： A syringe is received within a housing, the syringe having a bore terminating at a forward end in a hypodermic needle and at a rearward end in a flared opening in which a bung having a bore surrounded by a skirt is insertod. A drive element has a forward end consisting of a substantially flat annular region that bears upon the skirt of the bung and surrounds a conical middle region that is received in the bore of the bung. An actuator advances the drive element so as to advance the bung and discharge the contents through the needle. The opening in the rear of the synnge is flared by being provided with a radius. The combination of the radius at the opening and the projecting conical middle region of the drive element allows misalignments of the two to be managed during automated assembly.

摘要： An injection device is described. A syringe 114 is received within a housing, the syringe having a bore terminating at a forward end in a hypodermic needle 118 and at a rearward end in a flared opening 210 in which a bung 134a having a bore 206 surrounded by a skirt 208 is inserted. A drive element 134 has a forward end consisting of a substantially flat annular region 200 that bears upon the skirt 208 of the bung 134a and surrounds a conical middle region 202 that is received in the bore 206 of the bung 134a. An actuator advances the drive element 134 so as to advance the bung 134a and discharge the contents of the syringe through the needle 118. The opening 210 in the rear of the glass syringe is flared by being provided with a radius. The combination of the radius at the opening 210 and the projecting conical middle region 202 of the drive element allows misalignments of the two to be managed during automated assembly. This is because the conical middle region 202 either pass straight into the opening 210 of the syringe, or contact the radius, which guides them towards the centre of the syringe bore. The radius and the substantially flat annular region 200 and the central conical portion 202 of the drive element 134 are so shaped and dimensioned that axial misalignment between the syringe 114 and the drive element 134 during assembly of the injection device are corrected by, firstly, the conical middle region 202 of the drive element 134 riding up the radius to a point at which, secondly, the substantially flat annular region 200 also makes contact with and rides up the radius, to align the drive element 134 in the bore of the syringe 114.
