The invention relates to a device for inserting needles, including a body defined by a proximal end and a distal end, a mounting movably mounted inside the body, at least one needle secured to the mounting, a drive means suitable for driving the mounting towards said distal end, said mounting comprising a distal surface onto which the needle projects, said distal end comprising a contact area intended for contacting the tissue, the mounting being configured so as to reach a position, after activating the driving means, in which the distal surface thereof, relative to said proximal end, is more distant than said contact area, wherein the device is further configured so as to enable a gradual passive return movement of the mounting once said position has been reached.

Method and device for inserting needles

A device for inserting at least one hollow needle for the injection or withdrawal of a solution into/from a tissue, said device comprising a casing (), a plunger () movably mounted inside the casing, and propulsion means (and) suitable for driving the plunger towards the distal end () of the device by applying a force F(). The propulsion means and/or the plunger comprise retaining means () for joining the propulsion means and the plunger while the latter is moving, said retaining means releasing the plunger from the propulsion means when a force F() is exerted in the opposite direction to F(). Pressure means hold the needle in the tissue and allow a controlled withdrawal of the plunger at least while the solution is being injected.

Device for inserting needles

Cannula inserter comprising a casing with a distal end, intended to be placed in proximity to the skin of a patient, and an opposite proximal end, a piston fixed at least temporarily by retaining means, drive means designed to exert a propulsion force of the piston in the direction counter to the trigger, and release means intended to release the piston; the inserter additionally comprising a needle fixed to a support; the piston being mounted in the casing in such a way that, once released, it reaches and remains temporarily in a first position, then a second position; the needle and its support also being arranged so as to be able to be driven by the piston in a direction corresponding to the main orientation of the casing, before the piston reaches said first position, and so as to be able to effect an automatic rotation about an axis perpendicular to said main orientation during the movement of the piston between said first position and said second position.
