The exterior of the catheter is also coated in a similar manner to inhibit microbes migrating toward the bladder along the outer surface of the catheter. The system includes a flow rate control device which may be a one-way valve, a filter or both. A collection bag is coupled to the control device. The interconnecting hoses, the flow rate control device(s) and the collection bag are also coated on the interior with oligodynamic metal, preferably silver, and also with a more noble metal, preferably platinum.Field of SearchBody inserted tubular conduit structure (e.g., needles, cannulas, nozzles, trocars, catheters, etc.)With body soluble, antibactericidal or lubricating materials on conduit Receptacle attached to or inserted within body to receive discharge therefrom Receptacle or portion thereof inserted within body cavity | |
