Abstract

Abstract To impart energy to living organism an appartus is provided which emits infra-red radiation towards an area of skin and has fan means for directing a current of cool air towards the same area of the skin. The fan means are not interposed between the infra-red radiator and the area of skin to be heated so as to be able to blow cold air and not hot air. The fan means and radiator are mounted on a common support member which can be preferably oriented with respect to the area of skin. The skin of the living organism has a dermis, epidermis, and a blood-circulating system. The radiator heats the area of the dermis and epidermis while the fan means cools the epidermis establishing a temperature difference therebetween.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 152 words
Apparatus for skin treatment comprising means for emitting infra-red radiation forwardly towards an area of skin; fan means for directing a current of cooler ambient air forwardly towards said area of skin; a common support upon which said radiation and fan means are mounted, the fan means comprising at least two fans spaced apart along said common support, each of said fans being spaced from said radiation means and the path of the radiation emitted therefrom and directed so as to enable simultaneous action of said radiation and fan means on said area of skin of a living organism of the kind having a dermis, epidermis and a blood circulating system, to heat said area of the dermis and epidermis with the infra-red radiation from said radiation means while cooling the epidermis in said area with the current of cooler ambient air from said fan means to establish a temperature difference therebetween.
Claim 2
Dependent Claim 152 words
Apparatus for skin treatment comprising means for emitting infra-red radiation forwardly towards an area of skin; fan means for directing a current of cooler ambient air forwardly towards said area of skin; a common support upon which said radiation and fan means are mounted, the fan means comprising at least two fans spaced apart along said common support, each of said fans being spaced from said radiation means and the path of the radiation emitted therefrom and directed so as to enable simultaneous action of said radiation and fan means on said area of skin of a living organism of the kind having a dermis, epidermis and a blood circulating system, to heat said area of the dermis and epidermis with the infra-red radiation from said radiation means while cooling the epidermis in said area with the current of cooler ambient air from said fan means to establish a temperature difference therebetween.
Claim 3
Dependent Claim 21 words
Apparatus as claimed in claim 1, including means for independent adjustment of at least one of said radiation or fan means.
