Abstract

According to the invention, the device (10) includes a needle holder (24) and an extraction assembly (27) comprising a needle protection armature (54) defining an inner volume. The holder (24) is movable relative to the armature (54) between an injection position and an extraction position of the needle. The device (10) includes a compressible envelope (28) for generating an overpressure in the injection passage of the needle (22). The envelope (28) is mechanically stacked between a contact surface (78) with the finger of an operator and a surface bearing against the body (14) to be compressed by the application on the contact surface of a force for maintaining the bearing surface against the body (14) when the bearing surface is in contact with the body (14) when withdrawing the needle.
