A fluid product dispensing device having a reservoir with a dose of fluid product, a piston-stopper mounted to slide in the reservoir, a dispensing head with a dispensing orifice axially movable to move the piston-stopper to dispense the fluid product. The piston-stopper has a hollow sleeve with a central receiving zone substantially at the axial and radial center of the piston plug. A shut-off element is positioned in the central receiving zone in a shutting-off position and, during actuation, expelled from the shutting-off position towards an open position. The central receiving zone is extended axially on one side by a lower receiving zone having two wall parts separated by at two axially extending radial grooves, the wall parts holding the shut-off element in its open position, with the fluid product able, during actuation, to flow from the reservoir around the shut-off element in the open position towards the dispensing orifice.

Device for dispensing a fluid product

An autoinjector having a body () receiving a reservoir (S), the reservoir containing fluid and including a piston (P); a piston rod () adapted to co-operate with the piston (P) of the reservoir (S), the piston rod () movable by an injection spring () between a primed position and an injection position in which the piston rod () has moved the piston (P) of the reservoir (S); and an indicator device for indicating that the autoinjector may be removed from the injection site. The autoinjector includes a retarding system for delaying actuation of the indicator device relative to the end of injection, the retarding system including a dashpot () containing a fluid and a piston () arranged in the dashpot (). The retarding system has the dashpot (), the piston (), a retarding spring (), a locking key (), and the piston rod (), and the piston rod ().

Auto-injector

An auto-injector having a body () receiving a reservoir (S) and including a piston (P); a piston rod () movable between a primed position and an injection position in which the piston rod () has moved the piston (P) to inject fluid into an injection site; and a visual, audible, and/or tactile indicator device for indicating that the autoinjector may be removed from the injection site. The autoinjector includes a retarding system to delay actuating the indicator device relative to the end of injection and that includes a dashpot (), a shear member () and a fluid. The dashpot or the shear member is rotatably mounted in the body and the other is stationary in rotation, the turning of one relative to the other being braked by shearing the fluid contained in the dashpot. The dashpot and shear member include projections that impede the flow of the fluid.

Auto-injector with a system for delaying the device indicating the removal of the auto-injector

An autoinjector having a body () receiving a reservoir (S) containing fluid and a piston (P); a piston rod () movable by an injection spring () between a primed position and an injection position; and a visual, audible, and/or tactile indicator for indicating the autoinjector may be removed from the injection site. The autoinjector including a retarding system for delaying actuation of the indicator relative to the end of injection, and including a dashpot () containing a fluid, a piston () in the dashpot, the dashpot or the piston movable in the body during actuation of the retarding system with the other stationary relative to the body, resulting in the fluid moving out from the dashpot through a flow passage () to brake movement.

Auto-injector with a delay system

An autoinjector having a body () receiving a reservoir (S), the reservoir containing fluid and including a piston (P), such as a pre-filled syringe, and stationary in said body (); a piston rod () that co-operates with the piston (P), the piston rod () movable between a primed position and an injection position in which the piston rod has moved the piston so as to inject the fluid into an injection site; and a visual, audible, and/or tactile indicator device for indicating to the user that the autoinjector may be removed from the injection site, the indicator device arranged at the rear end of the body (), remote from the injection site. The autoinjector includes a retarding device to delay actuating the indicator device relative to the end of injection, the retarding device having an epicyclic gear train having at least one stage, and advantageously two stages.

Auto-injector with a delay device comprising an epicyclic gear train

An autoinjector having a body () receiving a reservoir (S) containing fluid and including a piston (P), such as a pre-filled syringe; a piston rod () that co-operates with the piston (P), the piston rod () being movable by an injection spring () between a primed position and an injection position in which the piston rod () has moved the piston (P) of the reservoir (S) so as to inject the fluid into an injection site; and an indicator device for indicating to the user that the autoinjector may be removed from said injection site. The autoinjector also includes a retarding system to delay the end of actuating the indicator device relative to the end of injection, the indicator device generating a noise while being actuated, the noise being generated until the end of actuating the indicator device.
