An infusion cannula (1) having an infusion channel, which defines a longitudinal axis, a pair of opposed wings (2), which extend in a direction perpendicular to said longitudinal axis, a valve socket (3), which projects substantially perpendicularly to said longitudinal axis and includes an injection channel, by means of which injection can be made during infusion, and a valve cap (4) for closing said injection channel. The valve cap (4) is pivotably mounted on two pivots (5), so that the opening of the injection channel can be opened or closed by pivoting said valve cap (4). The valve socket (3) together with the pivotable valve cap (4) are rotable relatively to said wings (2) around said longitudinal axis between an injection position, in which the valve socket (3) protrudes substantially perpendicularly to the wings (2), and a closed position, in which the valve socket (3) is substantially parallel to the wings (2). The valve socket (3) and the pivotable valve cap (4) are disposed at such a distance from the wings (2) that in said closed position, the valve cap (4) will lie close to one wing (2) and be prevented from being removed said valve socket (3) by abutting said one wing (2). wing (2) and be prevented from being removed said valve socket (3) by abutting said one wing (2). |
