ANTIMICROBIAL HOUSING AND COVER FOR A MEDICAL DEVICE

摘要

A method for immobilizing dyes and antimicrobial agents on a polymeric cover or housing for a medical device is disclosed and described. The surface may be that of a catheter, a connector, a drug vial spike, a bag spike, a prosthetic device, an endoscope, a surface of an infusion pump, a key pad, a touch screen or a handle. The surfaces may also be one or more of those associated with a infusion of a medicament or dialysis treatment, such as peritoneal dialysis or hemodialysis, where it is important that the 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.

主权项

1. A polymeric housing for a medical device comprising:
a polymer; a plurality of attachment sites on an least an outer surface of the polymer; a plurality of functional groups attached to the attachment sites; and a solvatochromic dye attached to the functional groups, wherein the outer surface is configured to reversibly change from a first appearance to a second appearance when the outer surface is swabbed with a disinfecting solution.
