Abstract
Abstract The ergometric device has an ergometric stationary bicycle exerciser, a hypoxic gas generator, a mask, and a flexible hose connecting the generator to the mask. The user of the device sits on the saddle of the exerciser, and produces his effort by inhaling, through the mask, the hypoxic mixture. His ECG, his pulse rate and his blood pressure appear on the screen of the generator.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
261 words
An ergometric device comprising exercising apparatus enabling a person to perform physical exercise and hypoxic gas generator means for supplying a hypoxic gas mixture to a person while exercising on said exercise apparatus, a mask to be worn by said person and a flexible hose connecting said hypoxic gas generator means with said mask, said hypoxic gas generator means comprising a cylindrical case having a side discharge opening connected by said flexible hose to said mask, a central tube extending axially of said case and having one closed end and one open end and having a plurality of openings in its side between said ends, a bundle of hollow permeable fibers in said case, said fibers extending lengthwise of said case and extending the full length of said case, said hollow fibers having the characteristics of being more permeable to one constituent gas of air than to another, closure means at opposite ends of said case for sealing spaces between said hollow fibers while leaving interiors of said hollow fibers open to the atmosphere, means for supplying air under pressure to said open end of said tube, said air flowing out of said openings in the side of said tube into said bundle of hollow fibers, a portion of a constituent gas of said air permeating walls of said hollow fibers to interiors of said hollow fibers and out through open ends of said hollow fibers while remaining constituent gases of said air flowing out through said side discharge opening of said case and through said flexible hose to said mask.
Claim 2
Dependent Claim
261 words
An ergometric device comprising exercising apparatus enabling a person to perform physical exercise and hypoxic gas generator means for supplying a hypoxic gas mixture to a person while exercising on said exercise apparatus, a mask to be worn by said person and a flexible hose connecting said hypoxic gas generator means with said mask, said hypoxic gas generator means comprising a cylindrical case having a side discharge opening connected by said flexible hose to said mask, a central tube extending axially of said case and having one closed end and one open end and having a plurality of openings in its side between said ends, a bundle of hollow permeable fibers in said case, said fibers extending lengthwise of said case and extending the full length of said case, said hollow fibers having the characteristics of being more permeable to one constituent gas of air than to another, closure means at opposite ends of said case for sealing spaces between said hollow fibers while leaving interiors of said hollow fibers open to the atmosphere, means for supplying air under pressure to said open end of said tube, said air flowing out of said openings in the side of said tube into said bundle of hollow fibers, a portion of a constituent gas of said air permeating walls of said hollow fibers to interiors of said hollow fibers and out through open ends of said hollow fibers while remaining constituent gases of said air flowing out through said side discharge opening of said case and through said flexible hose to said mask.
Claim 3
Dependent Claim
28 words
An ergometric device according to claims 1, further comprising control valve means for alternate supplying to said mask air and hypoxic gas from said hypoxic gas generator means.
Claim 4
Dependent Claim
40 words
An ergometric device according to claim 1, further comprising a housing for housing said hypoxic gas generator means and a display screen on said housing for displaying the pulse rate and blood pressure of a person using said exercising apparatus.
Claim 5
Dependent Claim
33 words
An ergometric device according to claim 3, further comprising on said housing programming means for programming treatment of a user of said device and for variably adjusting components of said hypoxic gas mixture.
Claim 6
Dependent Claim
22 words
An ergometric device according to claim 1, in which said hollow fibers of said hypoxic gas generating means are of poly 4-methyl-pentene-1.
Claim 7
Dependent Claim
30 words
An ergometric device according to claim 5, in which said hollow fibers have a wall thickness of 12 to 30 microns and an internal diameter of 8 to 20 microns.
