  • Patent number: 9314575
    Abstract: The device comprises a syringe (10, 11, 12) and safety means comprising a protective sheath (16) capable of adopting, relative to the syringe body, both an injection configuration in which the syringe needle (11) projects beyond said sheath, and a protection configuration in which the needle extends inside the sheath. The device includes a trigger member (30) enabling it to pass from the injection configuration to the protection configuration at the end of the injection stroke. It comprises means (34) for defining a first end-of-injection-stroke situation in which the trigger member (30) is unsuitable for causing the device to pass from the injection configuration to the protection configuration, and a second end-of-injection-stroke situation in which such passage is possible.

  • Patent number: 9220848
    Abstract: The invention relates to a device comprising a syringe body (10) having an axial direction (A) and a bearing sleeve (18) inside which the body is arranged. The sleeve has at least one holding lug (22) co-operating with the syringe body, at a proximal end (10A) of the latter, in order to hold the body in relation to the sleeve. Said proximal end is fixed to a wedging surface (42) having radial crenulations forming dips (42B) and bumps (42A) and the holding lug is inserted into a dip in order to prevent a relative rotation of the syringe body (10) and the sleeve perpendicularly to the axial direction.

  • Patent number: 9022990
    Abstract: A needle safety shield 10 for use with a syringe 10 having a barrel 14, a needle and a plunger rod 16. The safety shield 10 has a first tube 22. A second tube 26 is arranged for sliding movement within the first tube 22. A pin 46 is connected to one of the first and second tubes 22, 26. An activation ring 32 has a stop 72. A drive spring 34 biases the activation ring 32 in a proximal direction to place the stop 72 in engagement with the pin 46 to retain the first and second tubes 22, 26 in a retracted configuration. The movement of the plunger rod 16 to engage the activation ring 32 compresses the drive spring 34, moving the activation ring 32 distally, and moving the stop 72 out of engagement with the pin 46, allowing the drive spring 34 to move the first and second tubes 22, 26 into an extended configuration.

  • Patent number: 8771235
    Abstract: The invention comprises a syringe body (10) having a distal end (10B) fitted with an injection needle (14), at least one sheath (16, 18) inside which the body is positioned, and a protective cap (40) able to be retained relative to the syringe body (10) to cover the needle (14) and be separate from this body to release the needle. The device comprises a non-return unit (50) able to oppose a refitting of the cap (40) in its protection position once the needle has been released. This non-return unit, for example, comprises an elastic lip (50) joined to the sheath or the cap.

  • Patent number: 8118787
    Abstract: The invention relates to a safety device comprising a supporting sleeve (16) for holding the syringe body (10), a protective sleeve (18), and at least one holding tongue (19, 20) which is rigidly connected to the protection sleeve and can be held by the supporting sleeve (16), in the holding position. The piston comprises a cylindrical skirt (13A) that can end up facing a part of the proximal end (16A) of the supporting sleeve, at the end of the injection stroke, in order to co-operate with an actuating part (19B, 20B) of the holding tongue, and to release same in such a way as to enable a relative sliding of the protection sleeve and the supporting sleeve in order to protect the neddle. This proximal end part (16A) has at least one deflection ramp (30, 32) that can co-operate with the skirt (13A), at the end of the piston stroke, in order to deform the skirt in such a way as to bring part of the skirt of the actuating part (19B, 20B) closer to the holding tongue (19, 20).
