Abstract
An apparatus and method for spray application of a burn treating agent is disclosed. The apparatus delivers substantially all of the treating agent from a flexible source thereof through a spray nozzle, preferably without bringing the agent into contact with ambient air or contaminants. In a preferred embodiment, silver sulfadiazine cream is sprayed on a burn wound by urging the cream toward an outlet in a collapsible bag in which the cream is disposed by means of pressure applied to the exterior surface of the bag and conveying the cream from the outlet to a sanitary spray nozzle by means of a compressed air operated sanitary pump.
