Abstract
A trans-dermal medication application cell for temporary attachment to the skin of a patient to facilitate the diffusion of medication solution from the cell's interior to the skin of a patient where it will be absorbed. A housing non-reactive with medication solutions is closed by a micro-porous diaphragm or membrane. A formed perforated medical foam sheet is secured to the housing and, in use, to the skin of a patient by a medical adhesive. A release sheet and vapor barrier secured to the foam sheet block exterior access to the micro-porous membrane and adhesive coated foam sheet prior to application to the patient's skin. A self locking and sealing plug closes the filling aperture in the housing in the principal invention embodiment.
