Summary for Patent: 4,936,487

Title:	Apparatus for treating portions of the human body
Abstract:	An apparatus for treating burn and scald wounds and localized disorders on portions of the human body which involves rapid cooling thereof by spraying a liquid from a first hand-held container onto the human body portion to be treated to form thereon a film of the liquid. Thereafter, a refrigerant is sprayed onto the film of liquid from a second hand-held container, the refrigerant being at a temperature low enough and at a flow rate high enough to freeze a substantial portion of the film of liquid. The human body portion is thereby rapidly cooled by heat absorbed by the frozen film.

Application Number:	07/264,531
Patent Claims:	1. Apparatus for treating burn and scald wounds and localized disorders on portions of the human body by rapid cooling thereof comprising: (a) portable, hand holdable means supporting first and second containers; (b) a liquid stored in said first container; (c) first manually operable means for spraying said liquid from said first container and for directing the sprayed liquid onto the body portion to be treated to form a film of said liquid thereon; (d) a refrigerant stored in said second container; and (e) second manually operable means of releasing said refrigerant from said second container and for directing the released refrigerant onto the film of said liquid formed on said body portion to freeze at least a substantial portion of said film to cause rapid cooling of said body portion; (f) properties of the liquid stored in said first container and of the refrigerant stored in said second container being selected such that the refrigerant stored in said second container is capable of freezing the liquid stored in said first container when said liquid is sprayed onto selected body portions in liquid film form and said refrigerant is released and directed onto said liquid film. 2. Apparatus as set forth in claim 1 in which said liquid stored in said first container is comprised substantially of stored sterile water and said refrigerant is a stored liquid under pressure in said second container. 3. Apparatus as set forth in claim 1 in which said portable, hand holdable supporting means comprises means integrally interconnecting said first and second containers to form a single, hand holdable device in which both of said first and second containers are supported in an operable configuration. 4. Apparatus as set forth in claim 3 in which said liquid stored in said first container is comprised substantially of stored sterile water and said refrigerant is a stored liquid under pressure in said second container. 5. Apparatus as set forth in claim 4 in which said means for spraying and directing said substantially sterile water liquid and said means for directing the released refrigerant are both pointed in the same direction.
