Injection device of fluid product () comprising a syringe body () and a needle () fixed in an axial end projection () of the syringe body, said injection device comprising a needle protection device (), said protection device being, in a storage position, fixed on said injection device, said protection device being removable from said injection device, said protection device comprising an inner body () made of substantially supple and/or deformable material and an outer body () made of substantially rigid material, said inner body (), in a storage position, sealingly closing the distribution orifice () of said needle () and sealingly cooperating with said injection device (), and said outer body () in a storage position, cooperating with said injection device () to fix said protection device () onto said injection device (), characterized in that said outer body () comprises a fixing part () fixed to said injection device () and a protection part () fixed to said inner body (), said protection part () being connected to said fixing part () by at least one breakable material bridge (), said at least one breakable material bridge () being broken to remove said protection part () and said inner body () from said injection device ().

Injection device having a needle protection device

An injection device including a needle protection system, said injection device including a delivery needle () that is provided with a delivery orifice (), said protection system comprising a removable needle guard () that, in a non-dispensing position, is adapted to be arranged on said needle () so as to protect and isolate said delivery orifice () of said needle (), said needle guard () including an isolator portion () made of flexible material, said delivery orifice () of the needle () being poked into said isolator portion () in the non-dispensing position, said needle guard () including at least one outwardly-radial projection (), said protection system further comprising an outer cap () that is provided with grip means () that are adapted to co-operate with said at least one radial projection () of said needle guard (), such that moving said outer cap () in the longitudinal direction of said needle (), away from said delivery orifice (), removes said needle guard () from the non-dispensing position, said at least one radial projection () being arranged at the distal axial end of said needle guard (), said at least one radial projection () being formed on a rigid outer structure () of said needle guard ().

Injection device having a needle protection system

A fluid injection device having a syringe body, a needle, and a needle protection device. The protection device includes a substantially flexible or deformable inner body and a substantially rigid outer body. The inner body closes a dispenser orifice of the needle, and co-operates with the syringe body in a leaktight manner, and the outer body fastens the protection device on the syringe body. The inner body includes a radial projection, and the outer body includes a radial shoulder and an axial end edge that defines a top axial opening. The inner body is inserted in the outer body, through the top axial opening, with the radial projection in abutment against the radial shoulder, the axial end edge of the outer body folded down on the inner body so as to fasten the inner body in the outer body.

Needle protection device

Injection device of fluid product () comprising a syringe body () and a needle () fixed in an axial end projection () of the syringe body, said end projection () comprising an axial end surface (), said injection device comprising a needle protection device (), said protection device being, in a storage position, fixed on said injection device, said protection device being removable from said injection device, said protection device comprising an inner body () made of substantially supple and/or deformable material and an outer body () made of substantially rigid material, said inner body (), in a storage position, sealingly closing the distribution orifice () of said needle () and sealingly cooperating with said injection device (), and said outer body () comprising a fixing part () which, in a storage position, cooperates with a shoulder () of said injection device () for fixing said protection device () on said injection device (), said inner body () comprising a proximal axial end edge () adapted, in a storage position, to sealingly cooperate with the syringe body () only with said axial end surface (), said inner body () being made of material having the following properties: a hardness greater than 55 Shore A, in particular greater than 60 Shore A, an elasticity greater than 8 MPa, in particular greater than 10 MPa, a compression set less than 30%, in particular less than 25%, a density greater than 1, in particular greater than 1.3.

A fluid injection device having a syringe body, a needle, and a needle protection device removable from the injection device and having a substantially flexible or deformable inner body and a substantially rigid outer body. In the stored position the inner body closes the dispenser orifice of the needle and the outer body co-operates with the injection device to fasten the protection device on the injection device. The protection device includes a protection system against accidental pricking, having protective flaps that are integral part of the outer body and movable between a covering position in which they cover the needle, and an open position in which the needle is uncovered. The protection system has a control ring that slides over the outer body so as to move the flaps from their covering position to their open position, before injection, and from their open position to their covering position, after injection.
