Abstract
A wetted, disposable wipe constructed by bonding a layer of absorbent material to one side of a barrier sheet that is impermeable to infectious agents and insoluble in dermatological fluids, filling a reservoir in the barrier with a dermatological fluid, and hermetically sealing the absorbent layer between the barrier and a cover. The peripheral edges of the absorbent layer are spaced inwardly from the peripheral edges of the barrier to provide a surrounding zone of the impermeable barrier alone. The absorbent layer bond to the barrier is resistant to degradation caused by exposure to the dermatological fluid. The cover is secured by an adhesive that is resistant to degradation caused by exposure to the dermatological fluid and that allows the cover to be manually peeled from the barrier. The reservoir holds the dermatological fluid temporarily to prevent vapors from the fluid from igniting during the barrier/cover sealing process.
