Axial movement preventing device for elongated member, e.g. cannula needle applied through skin of mammal, comprises clamping mechanism that is thin and flat and provided with lateral opening

An axial movement-preventing device comprises a clamping mechanism (8) that is thin and flat and provided with a lateral opening (10) for laterally introducing an elongated member (1) between clamping portions (11, 12). The clamping mechanism includes parts of rigid material provided with clamping portions adapted to bear against the elongated member. An axial movement-preventing device comprises a plaster (2) to cover a surface around a puncturing position and having an adhesive layer (4) for securing it to a skin as well as an opening (9) through the layer for the passage of an elongated member. It further comprises mechanism secured to the plaster and adapted to clamp around the member when the member is applied through the skin of a mammal and the plaster is applied on the surface around the puncturing position. The clamping mechanism is thin and flat and provided with a lateral opening for laterally introducing an elongated member between clamping portions. It includes parts of rigid material provided with clamping portions adapted to bear against the elongated member.
