US 6,273,873 B1 · Fixation device for fixating a catheter relative to a skin surface part of a person

Abstract

A fixation device for fixating a catheter relative to a skin surface part of a person which 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 fixation device comprises a pad element to be arranged adjacent to the perforation site and defining 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 fixation device further comprises a cover foil of a foil material having opposite first and second surfaces and defining a first end, an adhesive material applied to the first surface of the cover foil, and a connecting foil being connected to the cover foil at the first end thereof and constituting an extension thereof. The pad element is connected to and supported by the connecting foil, which defines a transition area between the supporting element and the cover foil. A folding line is defined within the transition area and the cover foil is foldable onto the pad element along the folding line for arranging the first surface of the cover foil facing towards the pad element for adhering to the skin surface part, for fixating the catheter relative to the pad element and for covering the perforation site.

Dependent claims

A fixation device for fixating a catheter relative to a skin surface part of a person, said catheter defining an outer diameter and being introduced into the interior of said person through said skin surface part substantially perpendicularly relative thereto through a perforation site, comprising:

a pad element having a major surface to be arranged in parallel relationship with said skin surface part in a position adjacent to said perforation site and further having an outwardly curved convex marginal surface extending transversely relative to said major surface and having a radius of curvature of at least one order of magnitude larger than said outer diameter of said catheter, said marginal surface providing a support surface in relation to said catheter positioned in facial contact therewith for arranging said catheter in a loop that lies in a plane that is substantially parallel to the major surface of the pad, and turning said catheter from an orientation substantially perpendicular relative to said skin surface part to an orientation substantially parallel with said skin surface part and for preventing said catheter from sliding along said marginal surface,
a cover foil of a foil material having opposite first and second surfaces and defining a first end,
an adhesive material applied to said first surface of said cover foil, and
a connecting foil being connected to said cover foil at said first end thereof and constituting an extension thereof, said pad element being connected to and supported by said connecting foil, said connecting foil defining a transition area between said supporting element and said cover foil, a folding line being defined within said transition area, said cover foil being foldable onto said pad element along said folding line for arranging said first surface of said cover foil facing towards said pad element for adhering to said skin surface part, for fixating said catheter relative to said pad element and for covering said perforation site.

A catheter fixation system for use at a perforation site on the skin surface of a person, the system comprising:

a catheter having an outer diameter dimensioned for introduction through the skin surface at the perforation site;
and
a device for fixating the catheter relative to the skin surface, the device comprising:
a pad element having a major surface to be arranged in parallel relationship with said skin surface in a position adjacent to said perforation site and further having an outwardly curved convex marginal surface extending transversely relative to said major surface and having a radius of curvature of at least one order of magnitude larger than said outer diameter of said catheter, said marginal surface providing a support surface in relation to said catheter positioned in facial contact therewith for (a) arranging said catheter in a loop that lies in a plane that is substantially parallel to the major surface of the pad, (b) turning said catheter from an orientation substantially perpendicular relative to said skin surface to an orientation substantially parallel with said skin surface, and (c) preventing said catheter from sliding along said marginal surface;
a cover foil of a foil material having opposite first and second surfaces and defining a first end;
