Summary for Patent: 4,802,480

Title:	Method for treating portions of the human body
Abstract:	A method of treating burns and scald wounds on the human body by rapid cooling which includes spraying liquid from a hand-held container and directing the liquid to the portion of the human body to be treated to form a film of liquid and then spraying and directing onto the film of liquid from a second hand-held container a refrigerant at a temperature low enough and a flow rate high enough to freeze a substantial portion of the film of liquid so that the human body is rapidly cooled by the heat absorbed from the frozen film. An apparatus accomplishing the method includes a portable hand-holdable support with two containers, one having sprayable liquid and the other having a refrigerant.

Patent Claims:	1. A method of treating burn and scald wounds and localized disorders on portions of the human body by rapid cooling thereof comprising the steps of: (a) spraying a liquid from a first hand held container; (b) directing the sprayed liquid at the human body portion to be treated to form thereon a film of said liquid; and (c) spraying and directing onto said film of liquid from a second hand held container a refrigerant at a temperature low enough and at a flow rate high enough to freeze a substantial portion of said film of liquid, whereby said human body portion is rapidly cooled by heat absorbed by the frozen film, and wherein the steps of spraying a liquid from a first hand held container and of spraying a refrigerant from a second hand held container are performed with said first and second containers provided in a single hand held device. 2. The method of claim 1 in which said liquid is comprised substantially of sterile water. 3. The method of claim 1 in which said liquid is comprised substantially of stored sterile water and in which said refrigerant is a stored liquid under pressure in said second container and in which the low temperature of the refrigerant is achieved by evaporation.
