Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
196 words
In a device for carrying out cryotherapy on the entire body of a patient with a cryogenic treatment gas consisting of a treatment chamber of insulating material for taking up the patient, which has connections for the supply and exhaust of the cryogenic treatment gas, the improvement being in that said treatment chamber is designed as a half shell, said half shell having a rear part and a side part on each side of said rear part with substantially its entire front being permanently open to permit a patient to freely walk into and out of said half shell and to permit an operator to readily monitor the treatment and to readily walk into said half shell during the treatment, said rear part having exhaust openings for the exhaust of the cryogenic treatment gas; and cryogenic treatment gas supply means, supply openings in said side parts of said half shell, said supply means feeding said cryogenic treatment to said supply openings, said supply openings being located laterally opposite said exhaust openings whereby the location of said supply and exhaust opening comprises means for flowing the treatment gas in a generally horizontal direction across said half shell.
