Abstract

Abstract A cooling chamber is positioned over the face or other areas of the body to direct cold air onto the injured tissues to retard or prevent swelling following plastic surgery. The device includes a domed wall or helmet which accommodates the head or body portion. Cold air from an air conditioning unit passes through a flexible hose into an inlet in the domed wall which widens into an open ended chamber. The air is distributed around the chamber by radial partitions or an inner porous wall which forms an air passageway for directing air into the desired areas. Hinged sections may provide selective compartments in the chamber to direct the air flow to specific facial areas. The unit may be adjustable, transportable and self-contained or attached to a wheeled table or bed.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 93 words
A cooling device comprising: a chamber having a domed wall open at one end and an inlet spaced from said open end, said open end being adapted to receive a portion of a body, cooling means supplying cold air to said inlet, a flexible conduit connected between said cooling means and said inlet, means for distributing said cold air around said domed wall, and a plurality of hinged compartments extending over the head and facial areas of said body to direct said cold air to selective portions of said head and facial areas.
Claim 2
Dependent Claim 93 words
A cooling device comprising: a chamber having a domed wall open at one end and an inlet spaced from said open end, said open end being adapted to receive a portion of a body, cooling means supplying cold air to said inlet, a flexible conduit connected between said cooling means and said inlet, means for distributing said cold air around said domed wall, and a plurality of hinged compartments extending over the head and facial areas of said body to direct said cold air to selective portions of said head and facial areas.
Claim 3
Dependent Claim 23 words
The device of claim 1 wherein said distributing means includes a plurality of partitions extending radially around said inlet toward said open end.
Claim 4
Dependent Claim 63 words
The device of claim 1 wherein said distributing means includes an inner curved wall spaced from said domed wall and providing an air passageway between said walls, and a plurality of apertures in said inner wall passing said cold air into said chamber, said device further including a wheeled base, said cooling means, flexible conduit and chamber being mounted on said wheeled base.
Claim 5
Dependent Claim 17 words
The device of claim 3 including means for blocking air flow through portions of said inner wall.
Claim 6
Dependent Claim 36 words
