Abstract

Abstract A disposable dermatological compress for the application of aqueous solutions to the skin to achieve evaporative cooling includes a body of water-permeable material constructed as a multi-layer device. An inner layer of smooth sheeting is directly applied to the skin. An intermediate layer of water-absorbing material functions as a reservoir to retain a large quantity of solution. An outer evaporation layer receives the solutions from the reservoir for evaporation. The evaporation layer has a surface area which is several times larger than the area defined by the outer boundaries of the unit to serve as an efficient evaporator.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 37 words
A disposable dermatological compress as recited in claim 1 wherein: said smooth surface portion includes a layer of porous sheeting; and said evaporation surface portion includes a layer of porous material having a textured surface for evaporation.
Claim 2
Dependent Claim 26 words
A disposable dermatological compress as recited in claim 2 wherein said reservoir material passes exudates from the skin to said evaporation surface layer for absorption thereby.
Claim 3
Dependent Claim 31 words
A disposable dermatological compress as recited in claim 3 wherein said layers have generally similar shapes and dimensions of the peripheral boundaries thereof and are assembled together in a unitary construction.
Claim 4
Dependent Claim 164 words
A composite package comprising: a container of non-absorptive impermeable material; and packaged therein a disposable dermatological compress for the application of water and aqueous solutions to the skin to achieve evaporative cooling; said compress including: a body of water permeable material having a portion forming an outer smooth surface for application to the skin without adhering thereto, another portion forming an outer evaporation surface, and an intermediate reservoir portion in communication with the other portions over substantially the entire surfaces thereof and of material capable of absorbing and retaining a large quantity of aqueous solution, said evaporation surface portion being formed of material of sufficient absorbency so that aqueous solution would tend to flow to said evaporation portion from said reservoir portion and having at least one projection to provide an area for evaporation substantially greater than the area of said smooth surface so that efficient cooling of the covered skin area is achieved, and an astringent dermatological solution retained in said reservoir portion.
Claim 5
Dependent Claim 141 words
A disposable dermatological compress for the application of water or aqueous or alcoholic solutions to the skin to achieve evaporative cooling comprising: a body of water permeable material having a portion forming an outer smooth surface for application to the skin without adhering thereto, another portion forming an outer evaporation surface, and an intermediate reservoir portion in communication with the other portions over substantially the entire surfaces thereof and of material capable of absorbing and retaining a large quantity of aqueous or alcoholic solution, said evaporation surface portion being formed of material of sufficient absorbency so that said solution would tend to flow to said evaporation portion from said reservoir portion and having projections to provide an area for evaporation substantially greater than the area of said outer smooth surface, so that efficient cooling of the covered skin area is achieved.
Claim 6
Dependent Claim 45 words
A disposable dermatological compress for the application of water or aqueous or alcoholic solutions to the skin to achieve evaporative cooling as recited in claim 6, wherein said reservoir portion is impregnated with an active medication in powdered state for producing an astringent dermatological solution.
