The invention relates to a cannula fixing strip for attaching cannulas to the human body, comprising a foam carrier body provided with an adhesive coating on one side, which is
The opposite side is provided with a laminating film, whereby the laminating film carries the adhesive strip for attaching the cannula.

Such cannula fixing strips are known. The adhesive coatings of both the strip itself on the surface intended for sticking to the human skin and on the fixing strip for the cannula are, at least in some areas, covered in practice with abhesive paper, e.g. silicone paper. When used, this paper is removed and the strip is stuck to the human skin. In order to be able to attach the cannula, half of the fastening strip is already used for the
Channels are glued to the support body, ie to its laminating film, the other half is protected with an abhesive paper, which is peeled off to glue the cannula.

If the cannula is to be removed again, the adhesive fastening strip must be removed again. In practice, it has been shown that this removal leads to
can lead to difficulties, as often the adhesive bond

between the adhesive strip and the laminated cover film is stronger than the adhesive bond between the strip and the human body. This makes handling more difficult.

The object of the invention is to create a solution with which, in particular, the removal of the upper adhesive strip for securing the cannula is simplified and facilitated*

In a cannula fixing strip of the type described above, this object is achieved according to the invention in that the laminating film is provided with an abhesive coating at least in one front edge area.

The invention ensures that when the adhesive fastening strip is removed, a part of the foam carrier body is already exposed, since the abhesive coating prevents the adhesive strip from sticking here. The user can therefore place a fingertip here, for example, and tear off the rest*. This keeps the cannula fixing strips in place.

The invention is particularly advantageous when the cannula fixing strip is used multiple times, i.e. once it has been glued to the human body it is used multiple times to fix cannulas, as is often the case in practice. The laminated and

The surface of the foam carrier body provided with the adhesive coating can be covered again and again with adhesive strips* The invention makes their removal particularly easy.

In one embodiment, the invention provides that the abhesive coating is arranged in a width of approximately 1/10 to 1/20 of the fixing strip length on an edge region, whereby the adhesive tape securing the cannula projects beyond this edge region of the foam carrier body in the position of use.

In a modified embodiment, the invention can also provide that an abhesive coating is provided on both edge areas, which means that the adhesive tape for fixing the cannulas can be removed from both sides.

The invention is explained in more detail below with reference to the drawing, for example.* This shows a cannula fixing strip according to the invention in a simplified, three-dimensional representation.

The cannula fixing strip, generally designated 1, is essentially formed by a foam carrier body 2, which has an adhesive layer 3 on its underside for fastening the foam carrier body 2 to the human body.

If the cannula is now to be removed again, the user lifts up the protruding part of the adhesive strip 5 or 5". The adhesive coating 9 immediately exposes the front edge area 8 of the foam support body 2. The user can now support himself there with a finger and remove the adhesive tape 5 completely or at least to the extent that the cannula 11 is exposed.

The abhesive coating 9 can also be provided on both outer edges or all around the edges of the foam carrier body, this is not shown in more detail in the figure.
