A fixation device for fixating a catheter relative to a skin surface part of a person, the catheter defines an outer diameter and is introduced into the interior of the person through the skin surface part substantially perpendicularly relative thereto through a perforation site. The device comprises a basic foil of a foil material having opposite first and second surfaces and defining a first end. A first adhesive coating is applied to the first surface of the basic foil. A first pad is included in the device and is intended to be arranged adjacent to the perforation site and defines a convex marginal surface having a radius of curvature of at least one order of magnitude larger than the outer diameter of the catheter. The marginal surface provides a support surface in relation to the catheter positioned in facial contact therewith for arranging the catheter in a loop and turning the catheter from an orientation substantially perpendicularly relative to the skin surface part to an orientation substantially parallelly with the skin surface part and for preventing the catheter from sliding along the marginal surface. The first pad is connected to and supported by the basic foil at the first surface of the basic foil. The device further includes a second adhesive coating applied to a part of the second surface of the basic foil below the first pad and defining a rectilinear adhesive material boundary line constituting a folding line for folding the basic foil onto the first pad in a specific position relative thereto and covering the first pad, and for arranging the first surface of the basic foil facing towards the first pad for adhering to the skin surface part, for fixating the catheter relative to the first pad and for covering the perforation site.L’invention a pour objet un dispositif de fixation d’un cathéter par rapport à une zone de la surface cutanée d’un patient, le cathéter définit un diamètre externe et est introduit dans l’organisme du patient à travers
