Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
129 words
Apparatus for the treatment of the common cold or allergic rhinitis comprising: controllable apparatus located in a first enclosure for providing a stream of heated pressurized gas; means for humidifying the stream of gas for providing a stream of heated and humidified gas including water droplets having an average droplet size of 4-8 microns; means for governing the temperature of said heated and humidified stream of gas to maintain the temperature at 43 degrees centigrade plus or minus 0.5 degrees centigrade; means having an outlet for directing an unconfined volume of said heated and humidified gas around the nasal mucosa of a patient without requiring inhalation by the patient; and means for maintaining an unconfined minimum separation of 1 cm between said outlet and the nostrils of a patient.
Claim 2
Dependent Claim
129 words
Apparatus for the treatment of the common cold or allergic rhinitis comprising: controllable apparatus located in a first enclosure for providing a stream of heated pressurized gas; means for humidifying the stream of gas for providing a stream of heated and humidified gas including water droplets having an average droplet size of 4-8 microns; means for governing the temperature of said heated and humidified stream of gas to maintain the temperature at 43 degrees centigrade plus or minus 0.5 degrees centigrade; means having an outlet for directing an unconfined volume of said heated and humidified gas around the nasal mucosa of a patient without requiring inhalation by the patient; and means for maintaining an unconfined minimum separation of 1 cm between said outlet and the nostrils of a patient.
Claim 3
Dependent Claim
42 words
Apparatus for treatment of the common cold or allergic rhinitis according to claim 1 wherein the controllable apparatus provides a stream of gas at a pressure selected such that when the stream impinges on the nasal mucosa its pressure is near zero.
Claim 4
Dependent Claim
67 words
Apparatus for treatment of the common cold or allergic rhinitis according to claim 1 and wherein said means for directing provides said stream of heated and humidified gas to the nasal mucosa with a predetermined amount of kinetic energy sufficient to enable said stream to reach said nasal mucosa but not ordinarily sufficient to enable it to reach therebeyond in the absence of inhalation by the patient.
Claim 5
Dependent Claim
28 words
Apparatus according to claim 1 and wherein said apparatus is operative to deliver said stream of heated and humidified gas at a rate of 33 liters per minute.
Claim 6
Independent Claim
115 words
A method for treatment of the common cold or allergic rhinitis comprising the steps of: providing a stream of heated pressurized gas from an apparatus; humidifying the stream of gas for providing a stream of heated and humidified gas including water droplets of an average droplet size of 4-8 microns; maintaining the temperature of said heated and humidified stream of gas at 43 degrees centigrade plus or minus 0.5 degrees centigrade; directing an unconfined volume of said heated and humidified gas around the nasal mucosa of a patient without requiring inhalation by the patient; and maintaining an unconfined minimum separation of 1 cm between apparatus said outlet of said and the nostrils of a patient.
Claim 7
Independent Claim
115 words
A method for treatment of the common cold or allergic rhinitis comprising the steps of: providing a stream of heated pressurized gas from an apparatus; humidifying the stream of gas for providing a stream of heated and humidified gas including water droplets of an average droplet size of 4-8 microns; maintaining the temperature of said heated and humidified stream of gas at 43 degrees centigrade plus or minus 0.5 degrees centigrade; directing an unconfined volume of said heated and humidified gas around the nasal mucosa of a patient without requiring inhalation by the patient; and maintaining an unconfined minimum separation of 1 cm between apparatus said outlet of said and the nostrils of a patient.
Claim 8
Dependent Claim
14 words
A method for treatment according to claim 5 and wherein said gas is air.
Claim 9
Dependent Claim
25 words
A method according to claim 5 and wherein said providing step comprises the step of providing 33 liters per minute of said stream of gas.
