Abstract: Anti-prick device for safe manipulation of an angled injection needle through the skin to supply an implanted chamber under the skin comprises three articulated panels, namely a four-lobed base panel, a needle-carrying panel and a covering panel. Two opposite lobes of the base panel are precurved to facilitate their application onto the skin; the other two lobes can be bent by the pressure of two fingers of one hand in order to retain the chamber when the operator retracts the needle with the other hand. Anti-prick device for safe manipulation of an injection needle through the skin to supply an implanted chamber under the skin, where the needle comprises a distal perforating branch at an angle to a proximal supply branch, comprises a wall of three articulated panels allowing the wall to be put in a configuation where a needle-carrying panel (2) is folded onto a base panel (1) and a covering panel (3) is folded onto the needle-carrying panel and fixed thereto, and to be put in a configuation where the needle-carrying panel and the covering panel, fixed to one another, are moved away from the base panel to create a space big enough to contain the distal branch of the needle. The base panel and needle-carrying panel have perforations (4, 6) through which the distal branch can be passed until the proximal branch rests on the needle-carrying panel and can be covered by the covering panel. The base panel has four lateral lobes around a central area (1a) containing its perforation and the needle-carrying panel has two lateral wings (2a, 2b) that can be grasped during insertion and retraction of the needle. The novelty lies in the fact that two opposite lobes (1b, 1d) of the base panel are precurved to facilitate their application onto the skin; the other two lobes (1c, 1e) can be bent by the pressure of two fingers of one hand in order to retain the chamber when the operator retracts the needle with the other hand; and the needle-carrying panel and covering panel are joined to the precurved lobes and have opposite curvature to the lobes so that they follow the curvature of the lobes when folded onto the base panel.
