<p>The present invention relates to port cannula systems for puncturing implantable and implanted port catheters. The invention describes a port cannula system comprising a cannula holder, a cannula affixed to the cannula holder with a cannula tip which can be moved into at least a puncture position and a secured position, a feeder connected to the cannula and at least one wing connected with the cannula holder for fastening the port cannula system to the patient's skin, wherein the at least one wing is connected to the cannula holder by means of a hinge. The hinge permits height compensation, if for example the patients skin is not even in the area of application or if the patient is moving. In this way, the wing, in conjunction with the hinge, represents a kind of levelling element.</p> |
