SCHUTZVORRICHTUNG FÜR EIN INVASIVES ELEMENT IN FORM EINER NADEL

The invention concerns a device (10) for protecting a needle-type invasive element (20) comprising an end tip, characterized in that it comprises a thin single-piece element, including a part (14) to be anchored for example to the invasive element spaced from the tip and a part (16) for protecting the tip, the thin element being configured such that it can adopt two stable positions, one first position wherein the protective part covers the tip, and a second position wherein the protective part is cleared from the tip enabling invasion. The device can co-operate with a needle mounted on a device designed to contain fluid, in particular for injecting a therapeutic liquid or for sampling a body fluid. The invention is characterized in that it comprises a part for mounting the invasive element, defining a global axis of the device, and a single-piece sheath deformable essentially along said axis.
