The invention relates to means and methods for the disinfection of an insertion channel to prevent in particular catheter sepsis, which significantly reduces the carry-over of germs even out of deeper skin layers by means of medical instruments, such as catheters, to be introduced into non-natural openings and also permits the decontamination of perioperatively contaminated medical instruments. The disinfection of the insertion channel is achieved by means of a method for the perioperative coating of a medical instrument to be inserted into an invasively produced bodily opening before use, comprising the application of a preferably viscous or foam-like composition containing at least one anti-infective compound, preferably a gel having octenidine, by means of an applicator, such that when said gel is used, the composition is also specifically effective in the first millimeters of the insertion channel. Furthermore, an immediate disinfecting action is provided over the entire coated surface.

1. An applicator for the perioperative disinfection of a medical instrument to be inserted into invasively generated body openings, with the applicator formed as an essentially hollow embodied reservoir with a conically tapering section such that a viscous or foam-like, anti-infectious composition can be retained in the reservoir and applied on a surface of the medical instrument by a relative motion between the applicator and said medical instrument as the medical instrument is guided through the entire length of the applicator and the applicator is located in the rear of the direction of motion. 2. The applicator according to claim 1, which comprises in an interior zone at least one reservoir or at least one carrier for the anti-infectious composition. 3. The applicator according to claim 1, with a cylindrical section following the conical section in the direction of motion. 4. The applicator according to claim 1, wherein the conically tapering section and/or the cylindrical section are open at the front end, seen in the direction of motion. 5. The applicator according to claim 1, with a retention device for the anti-infectious compound comprising an opening, which is additionally slotted. 6. The applicator according to claim 1, with the conically tapering section comprising a multitude of slots, embodied in the axial direction starting at the rear end of the conical section, seen in the direction of motion. 7. The applicator according to claim 1, with the conically tapering section essentially showing the form of a frustum. 8. The applicator according to claim 7, with a multitude of flexible tongues being formed by the slots. 9. The applicator according to claim 1, wherein the reservoir or the carrier are filled with a viscous, anti-infectious composition. 10. The applicator according to claim 1, with the applicator comprising laterally a slot, continuous in the axial direction. 11. The applicator according to claim 1, with the applicator comprising an insertion aid for the medial instrument at a continuous slot extending laterally in the axial direction. 12. The applicator according to claim 1, wherein at least two engagement zones are provided at its exterior. 13. The applicator according to claim 1, further comprising an anti-infectious composition wherein the composition is embodied to adhere on the medical instrument like a film after being brought into contact with the medical instrument, and that at least a portion of the composition adhering like a film reaches at least to the epidermis upon insertion of the medical instrument into the body. 14. The applicator according to claim 13, further comprising a vascular catheter.
