An autoinjector includes a body (), a reservoir containing fluid product, a piston, a needle, a piston rod () that is displaceable between a loaded position and an injection position, and an injection spring () to stress 10 the piston rod towards the injection position. The autoinjector also includes an injection lock having a control sleeve () containing the piston rod and the injection spring. The piston rod includes a radial recess () receiving a substantially spherical blocking element () mobile between a blocking position and an unblocking position, stressed radially towards the exterior by the piston rod, and held in the blocking position by a blocking member () that is displaceable relative to the piston rod to release the blocking element.

Autoinjector

An autoinjector includes a body (), a reservoir containing fluid product, a piston, a needle, a piston rod () that is displaceable between a loaded position and an injection position, and an injection spring () to stressthe piston rod towards the injection position. The autoinjector also includes an injection lock having a control sleeve () containing the piston rod and the injection spring. The piston rod includes a radial recess () receiving a substantially spherical blocking element () mobile between a blocking position and an unblocking position, stressed radially towards the exterior by the piston rod, and held in the blocking position by a blocking member () that is displaceable relative to the piston rod to release the blocking element.

An autoinjector having a lower body () receiving a reservoir, a piston, a needle, an actuating sleeve () with a contact end to contact the user. The actuating sleeve is displaceable between projected positions and an actuation position, being in a first projected position prior to actuation of the autoinjector. The autoinjector also having an injection device () and an injection lock. The actuating sleeve is automatically returns to the second projected position when the user removes the autoinjector from his body and is locked in this second projected position. The autoinjector includes an external shell () having a display window for indicating the actuation sequences, at least one display window () indicating to the user that the injection of the fluid product is finished.

An autoinjector having a body () receiving a reservoir, a piston, a needle, an actuatingsleeve () having a contact end to contact the body of the user and displaceable relative to the body between projected positions, in which the actuating sleeve at least partially projects out of the body receiving a reservoir, and an actuation position, in which the actuating sleeve is axially displaced towards the interior of the body receiving a reservoir. The actuating sleeve is in a first projected position prior to actuation of the autoinjector and in a second projected position after actuation of the autoinjector. The actuating sleeve or the body receives a reservoir having a flexible tab adapted to deform laterally relative to the actuating sleeve and/or relative to the body receiving a reservoir when the actuating sleeve is displaced from its first projected position towards its actuation position then from its return actuation position towards its second projected position.

An autoinjector having a lower body receiving a tank containing fluid product and a piston and a needle. The autoinjector including a central body fastened to the lower body and an actuating sleeve provided with a contact end that contacts the body of the user, the actuating sleeve moveable between a projected position and an actuation position. The actuating sleeve is in a projected position prior to and after actuation of the autoinjector, an injection mechanism is provided to inject the fluid product through the needle when the needle is in an injection position in which it is inserted in the body of the user. The autoinjector includes a tank movement device to move the needle towards the injection position, the tank movement device triggering the injection mechanism only after the needle has reached its injection position.

An autoinjector that receives a pre-filled syringe, having a central body and an actuator sleeve provided with one end that comes into contact with the user. The actuator sleeve can be moved between projecting and actuation positions and it is in the projecting position prior to and following the actuation of the autoinjector. An injection mechanism is provided to inject the product when the needle is inserted into the user's body. The autoinjector also includes a barrel movement device to move the needle into the injection position and retract the needle from the body following injection. The movement device includes a control ring rotatably mounted in the central body, the ring having an inclined internal profile that engages with an internal projection of a control sleeve that can move axially in the central body, such that the sleeve moves axially when the ring is rotated.

An autoinjector comprising a lower body () receiving a tank, said tank containing fluid product and comprising a piston and a needle, such as a pre-primed syringe (A), said autoinjector comprising:

Autoinjector comprising a time delay device having a planetary gear set for delaying the retraction of the needle

An autoinjector having a lower body () receiving a reservoir, a piston, a needle, a central body () fixed to the lower body, an actuating sleeve () having a contact end to contact the body of the user and displaceable in the lower body between a projected position, in which the actuating sleeve at least partially projects out of the lower body and an actuation position, in which the actuating sleeve is axially displaced towards the interior of the lower body. The actuating sleeve includes a flexible tab () adapted to deform on the one hand radially and on the other hand laterally relative to the central body when the actuating sleeve is displaced from its projected position towards its actuation position then from its return actuation position towards its projected position.

An autoinjector having an external shell (), a reservoir, a piston, a needle, a piston rod () that is displaceable between a loaded position and an injection position in which the piston rod has displaced the piston of the reservoir to inject the fluid product through the needle, an injection spring () to stress the piston rod towards the injection position, and a mobile element (), the piston rod displaceable relative to the mobile element. The autoinjector also includes an indication device () having a key (), and a head part (). The mobile element including a deformable tab (), the head part cooperating prior to injection with the deformable tab to prevent any radial deformation, blocking the mobile element relative to the external shell. The piston rod, on completion of injection, exerting traction on the head part causing displacement of the key and enabling radial deformation of the deformable tab and axial displacement of the mobile element.
