Patent Images
1. A port system, comprising:
- an implantable first fluid guiding system comprising a disc-shaped supporting body;
an external second fluid guiding system with a connecting head at one end, the connecting head comprising a connecting cannula and two connecting jowls arranged transverse to the connecting cannula, the connecting jowls forming a latching projection formed of a curved arc of greater than 180°
, the latching projection pointing radially inwardly to an underside of the connecting head, wherein the connecting jowls are each coupled to a grip element, the grip elements coupled to the connecting head such that a movement of the grip elements toward each other results in a radial splaying movement of the curved arc of the latching projection about an axis arranged perpendicular to the underside of the connecting head for facilitating connection of the connecting head; and
a percutaneously implantable port for establishing a fluid connection between said fluid guiding systems, said port comprising a port casing, which forms connecting elements protruding beyond the port casing and forming a radial protrusion configured to receive connecting head latching projection;
wherein said connecting head is fastened to said port casing by a releasable fastening engagement of said connecting elements and said connecting jowls upon the radial splaying movement of the connecting jowls.
