A safety needle device, particularly for puncturing a port implanted subcutaneously in a human or animal body, comprising: a first housing; a hollow needle, wherein the needle comprising a first sub-section and a second sub-section, the first sub-section extends along a puncture axis, which runs at a right angle to the surface of the human or animal body, and the second sub-section of the needle being arranged at a right angle to the first sub-section, substantially in parallel to the surface of the human or animal body, wherein the hollow needle being connected or connectable to the first housing, particularly in the region of the second sub-section; a cover comprising a through-hole for receiving said first sub-section of the needle, wherein the cover is being movable from a first position to a second position relative to said first housing, wherein the movement being substantially along said puncture axis; and an at least partially flexible limiting element which limiting the relative movement between the first housing and the cover in the second position, characterised in that the cover comprises on the surface facing away from the human or animal body a guide sleeve for the first sub-section of the needle, for guiding the relative movement between the cover and the first housing, so that the needle is removed from the port in the direction of the puncture axis, wherein the needle tip being arranged inside the guide sleeve in the second position, and characterised in that the first housing comprises two wings, which are foldable from a first orientation, which extends substantially perpendicular to the puncture axis, into a second orientation, substantially parallel to the puncture axis, wherein the surfaces of the wings facing away from the human or animal body in the first orientation are arranged directly adjacent to one another in the second orientation and are complementary to one another. a first housing; a hollow needle, wherein the needle comprising a first sub-section and a second sub-section, the first sub-section extends along a puncture axis, which runs at a right angle to the surface of the human or animal body, and the second sub-section of the needle being arranged at a right angle to the first sub-section, substantially in parallel to the surface of the human or animal body, wherein the hollow needle being connected or connectable to the first housing, particularly in the region of the second sub-section; a cover comprising a through-hole for receiving said first sub-section of the needle, wherein the cover is being movable from a first position to a second position relative to said first housing, wherein the movement being substantially along said puncture axis; and an at least partially flexible limiting element which limiting the relative movement between the first housing and the cover in the second position, characterised in that the cover comprises on the surface facing away from the human or animal body a guide sleeve for the first sub-section of the needle, for guiding the relative movement between the cover and the first housing, so that the needle is removed from the port in the direction of the puncture axis, wherein the needle tip being arranged inside the guide sleeve in the second position, and characterised in that the first housing comprises two wings, which are foldable from a first orientation, which extends substantially perpendicular to the puncture axis, into a second orientation, substantially parallel to the puncture axis, wherein the surfaces of the wings facing away from the human or animal body in the first orientation are arranged directly adjacent to one another in the second orientation and are complementary to one another.
