Abstract
A portable hypobaric sleeping chamber for acclimatization to high altitude or athletic conditioning is provided, capable of maintaining internal pressures about 0.1 to about 10 psi below ambient.
Claims6
A cylindrically-shaped hypobaric sleeping chamber with a length longer than its diameter having a size sufficient to accommodate no more than two reclining humans, having means for maintaining a selected internal pressure between 0.1 and 10 psi below the local ambient air pressure, and having means for providing fresh air to occupants of said chamber over a period of up to eight hours, said chamber further comprising:
- (a) an air-impermeable outer layer formed of essentially nonelastomeric material, and an inner frame of rigid or semi-rigid material, said outer layer and inner frame when formed into said cylindrically-shaped hypobaric chamber having sufficient strength to withstand an external collapsing pressure of approximately 30 psig;
- (b) a substantially airtight ingress and egress means through said air-impermeable material of a size sufficient to allow a human to pass therethrough;
- (c) said means for providing fresh air comprising a vacuum pressure release valve located in said air-impermeable material responsive to a predetermined decrease in said internal pressure within said hypobaric chamber below ambient pressure for pulling fresh ambient air into said chamber;
- (d) said means for maintaining said selected internal pressure comprising a vacuum maintenance orifice located within said air-impermeable material through which air is removed from said chamber;
- and
- (e) said cylindrically-shaped hypobaric sleeping chamber weighing approximately 200 pounds or less.
