Attorney, Agent or FirmInternational ClassA61F 013/02AbstractA topical medicating device includes a transparent viscoelastic gel pad having one or more pharmacologically-active substances incorporated therein; a sheet of transparent, impermeable, and elastic material providing an occlusive layer adjacent to the upper surface of the viscoelastic gel pad; an elastic retaining ring perimetrically surrounding the viscoelastic gel pad to prevent migration due to external pressure; and a porous meshwork attached to the elastic retaining ring so as to additionally anchor the gel pad from migration. The porous meshwork member may be located at the surface of the viscoelastic gel pad opposite the aforementioned occlusive covering sheet, or may run through the viscoelastic gel pad in its anchoring function. The viscoelastic gel pad, occlusive covering sheet, and retaining ring with porous meshwork may be affixed to a target skin surface of the patient by an adhesive tape bandage with a visual access opening. The adhesive bandage may be formed to integrally include the impermeable occlusive layer adjacent to the surface of the viscoelastic gel pad. As a topical anesthetic device, the liquid fraction of the viscoelastic gel pad may be a solution of alcohol and water, preferably, but not limited to, 70% ethyl alcohol, wherein is dissolved 10% to 40%, by weight, of Lidocaine, U.S.P./N.F.Field of SearchBandage, pad, or shield placed on body for sustained treatment thereofAdhesively attachable to body CONTROLLED RELEASE THERAPEUTIC DEVICE OR SYSTEM Osmotic or diffusion pumped device or system Wound contact layer containing treatment material Lipid (e.g., oil, fat, or wax) Skin laceration or wound cover BANDAGE STRUCTURE System for adhesive layer release (e.g., release sheet) Backing layer having particular structural feature (e.g., permeability, shaped, or elasticity, etc.) Perforated Bandages with incorporated medicaments Transdermal or percutaneous | |
