CA 2693500

A method for immobilizing dyes and antimicrobial agents on a porous surface is disclosed and described. The surface may be that of a medical device, such as a catheter, a connector, a drug vial spike, a bag spike, a prosthetic device, an endoscope, and surfaces of an infusion pump. The surfaces may also be one or more of those associated with a dialysis treatment, such as peritoneal dialysis or hemodialysis, where it is important that working surface for the dialysis fluid be sterile. These surfaces include connectors for peritoneal dialysis sets or for hemodialysis sets, bag spikes, dialysis catheters, and so forth. A method for determining whether a surface has been sterilized, and a dye useful in so indicating, is also disclosed.

L'invention concerne un procédé pour immobiliser des colorants et des agents antimicrobiens sur une surface poreuse. La surface peut être celle d'un dispositif médical, comme un cathéter, un connecteur, une pointe de flacon de médicament, une pointe de poche, un dispositif prothétique, un endoscope, et des surfaces d'une pompe à perfusion. Les surfaces peuvent être également une ou plusieurs de celles associées à un traitement de dialyse, comme une dialyse péritonéale ou une hémodialyse, où il est important que la surface de travail pour le fluide de dialyse soit stérile. Ces surfaces comprennent des connecteurs pour des ensembles de dialyse péritonéale ou pour des ensembles d'hémodialyse, des aiguilles de poche, des cathéters de dialyse, etc. Un procédé pour déterminer si une surface a été stérilisée, et un colorant utile pour l'indiquer, sont également décrits.
