Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
170 words
Apparatus for treatment of a user by periodic localized topical application of therapeutic combustion gases, said apparatus comprising a first chamber communicating with a blower pressurized air supply, a second chamber within said first chamber and defining an annular pressurized air supply plenum therewith, said second chamber comprising a combustion chamber having a grating adapted to support for combustion therapeutic gas-producing combustible material comprising herbs or the like, a third chamber beyond said combustion chamber grating and adapted to contain combustion gases generated within the combustion chamber, said third chamber having an opening for application of said gases to the user's skin, port means communicating said plenum with the interior of said combustion chamber for passage of pressurized air into the combustion chamber and for combustion of said combustible material, said pressurized air acting to differentially pressurize the combustion chamber to urge gaseous combustion products through said grating to said third chamber opening, and reduced gas outlet means in said third chamber to back-pressurize said third chamber during treatment periods.
Claim 2
Dependent Claim
170 words
Apparatus for treatment of a user by periodic localized topical application of therapeutic combustion gases, said apparatus comprising a first chamber communicating with a blower pressurized air supply, a second chamber within said first chamber and defining an annular pressurized air supply plenum therewith, said second chamber comprising a combustion chamber having a grating adapted to support for combustion therapeutic gas-producing combustible material comprising herbs or the like, a third chamber beyond said combustion chamber grating and adapted to contain combustion gases generated within the combustion chamber, said third chamber having an opening for application of said gases to the user's skin, port means communicating said plenum with the interior of said combustion chamber for passage of pressurized air into the combustion chamber and for combustion of said combustible material, said pressurized air acting to differentially pressurize the combustion chamber to urge gaseous combustion products through said grating to said third chamber opening, and reduced gas outlet means in said third chamber to back-pressurize said third chamber during treatment periods.
Claim 3
Dependent Claim
41 words
Apparatus according to claim 1 including also a blower and means to vary the blower output to correspondingly increase or decrease the pressurized air supply and the airflow through said combustion chamber ports thereby, to control rate of combustible material combustion.
Claim 4
Dependent Claim
28 words
Apparatus according to claim 2 including also means to variably restrict the gas outlet means of said third chamber to correspondingly vary the backpressurization of said third chamber.
Claim 5
Dependent Claim
109 words
Apparatus according to claim 2 in which: said first chamber is generally cylindrical and provided with an interfitting top and therebelow an annular shoulder defining a reduced diameter bottom opening; said second chamber is generally cylindrical, of lesser diameter than said first chamber and is supported within said first chamber on said annular shoulder, said second chamber grating being alined with said first chamber bottom opening, and including also, bottom opening enclosure structure adapted to rest upon the user's skin, said structure being apertured for skin exposure to gases passing the second chamber grating to and through the first chamber opening and defining said gas outlet beyond said aperturing.
Claim 6
Dependent Claim
40 words
Apparatus according to claim 4 including also wall structure between said first and second chamber upwardly defining said annular plenum, and a series of circularly distributed ports in said second chamber wall communicating the second chamber interior with said plenum.
Claim 7
Dependent Claim
31 words
Apparatus according to claim 5 including also a supply of therapeutic volatiles open to said second chamber and responsive to chamber combustion heat to deliver said volatiles into said second chamber.
Claim 8
Dependent Claim
38 words
Apparatus according to claim 6 in which said volatiles supply is supported opposite said grating and beyond said ports for entrainment of heat-generated volatiles into air-streams passing into the second chamber through said ports to said combustible material.
