The present invention relates to a device for providing an aerosol flow, an air flow or both with at least a compressor for providing an air flow, a nebulization device for generating an aerosol flow and a mixing means for optionally mixing the aerosol flow with the air flow to provide a total flow, wherein the total flow is composed of the aerosol flow, the air flow or both. When implanted on the sclera of an eye, the jacket protects the valve from interference by a capsule formed on the shunt. A first BCP structure is formed in each first opening. The invention takes advantage of the physical design of the wound dressing, and the permeation of body fluid into the dressing, which together serve to initiate formation of nascent iodine concomitant with placement of the dressing into, or over, a wound site.
