Method and applicator for the perioperative disinfection of medical instruments to be inserted through non-natural openings

A composition comprising at least one anti-infectious compound, wherein the composition is embodied to adhere like a film on the medical instrument upon being brought into contact with a medical instrument to be inserted preoperatively into an invasively generated body opening, and that at least a portion of the composition adhering like a film reaches at least the epidermis upon inserting the medical instrument into the body.

A medical instrument to be inserted into invasively generated body openings, from the group comprised of a vascular catheter, endoscope, pin, trocar, or electrode, with a preferably viscous or foam-like composition comprising an anti-infectious compound, such compound selected from the group comprised of chlorhexidine and octenidine, wherein the composition is embodied to adhere on the medical instrument like a film upon being brought into contact with it and that the film-like adhesive composition, upon inserting the medical instrument, reaches into the body at least to the epidermis.

A method for the production of at least one composition comprising an anti-infectious compound for the perioperative disinfection of a medical instrument to be inserted into an invasively generated body opening or for the disinfection of an insertion channel generated by the insertion of a medical instrument into the body, comprising the steps of:

• (a) producing a gel, preferably a PAA, or PVA gel in H2O with a pH ranging from 5 to 8,
• (b) dissolving an anti-infectious substance selected from octenidine and chlorhexidine in polyvinyl pyrrolidone, and
• (c) mixing the gel of (a) with the solution of (b) so that the PAA is present in the gel at a range from 0.1 and 2% by weight and PVA at a range from 0.1 and 20% by weight, the anti-infectious substance at a concentration from 0.01 to 2% by weight, and the polyvinyl pyrrolidone at a concentration from 0.1 to 5% by weight.

An applicator for the perioperative disinfection of a medical instrument to be inserted into invasively generated body openings, with the applicator being embodied such that a viscous or foam-like, anti-infectious composition can be applied on a surface of the medical instrument by a relative motion between the applicator and said medical instrument, wherein the applicator, preferably located in the rear in the direction of motion, comprises a retention device for the anti-infectious compound, with the applicator being formed as an essentially hollow embodied reservoir with a conically tapering section, preferably located at the rear in the direction of motion.
