A personal exercise apparatus that allows simultaneous simulation of mild to high altitude environments with algorithmically driven environmental stressors that may be pre-programmed or personally developed via physiological feedback during training. Additional stressors include an ability to transiently alter pressure in a chamber of the personal exercise apparatus at variable frequencies and amplitudes with a range of changes with an option of random pressure oscillations designed to personalize training programs. The additional stressors further include small variations in inspired CO2 levels and temperature allowing individuals to simulate breathing and temperature conditions in preparation for desired environmental conditions.

An escape pod includes a spherical survival chamber, a gimbal mechanism, and a spherical outer case body. The survival chamber is mounted on an inner side of the gimbal mechanism, and an outer side of the gimbal mechanism is mounted within the outer case body. Top and bottom ends of the outer case body are provided symmetrically with upper and lower connecting terminals. The outer case body includes a plurality of arc-shaped plates. Two ends of each arc-shaped plate are fixedly connected to the upper and lower connecting terminals respectively. An inner side of the arc-shaped plate is provided with a reinforcing framework. The reinforcing framework is formed of a plurality of arc-shaped steel pipes. Top and bottom ends of each arc-shaped steel pipe are connected to the upper and lower connecting terminals. One of the arc-shaped plates is provided with a pod door.

An isolation section assembly includes a section housing defining an interior space. The section housing includes a door with access to the interior space. The isolation section assembly includes an enclosure abutting the door. The airlock enclosure defines an interior airlock space. The interior airlock space is configured and adapted to be at a negative pressure relative to a cabin area. An air recirculation system in fluid communication with at least one of the interior space of the section housing or the interior airlock space.

A system which protects the user from electromagnetic radiation, in particular the eyes, face and/or head from UV radiation and/or excessive light as required, while also protecting from thrown particles, projectiles or fluids from striking a user, in particular the eyes, face and/or head, and at the same time providing clean air to breathe.

The present invention relates to a portable and foldable oxygen chamber, and more particularly, relates to a portable and foldable hyperbaric oxygen chamber that may be reduced in volume and conveniently carried and kept by including a tube capable of accommodating a patient and a body part which protects the tube and is divided into multiple cylindrical bodies formed in a longitudinal direction and inserted into and overlapped with one another.

An apparatus for controlling a level of oxygen in a closed environment from an oxygen supply having an oxygen sensor for detecting the level of oxygen in the closed environment. The apparatus has a plurality of relays in communication with the sensor. The apparatus has a valve in communication with the relays and the oxygen supply which is automatically opened with the relays without human interaction, monitoring and adjustment to release oxygen from the oxygen supply into the environment when the level of oxygen in the environment goes below a first predetermined level and which is automatically closed with the relays without human interaction, monitoring and adjustment to stop oxygen from being released from the oxygen supply into the environment when the level of oxygen in the environment goes above a second predetermined level. A method for controlling a level of oxygen in a closed environment from an oxygen supply. A refuge chamber.

A system and method of administrating conventional hyperbaric chamber therapy as well as supplemental oxygen therapy at ambient conditions to an animal using a veterinary hyperbaric chamber. The hyperbaric chamber can function in its usual mode of operation; i.e., providing oxygen at greater than atmospheric pressure and also in a second mode of operation to administer supplemental oxygen thereafter at ambient pressure conditions. In the second mode of operation, the method and apparatus may deliver approximately 80 liters per minute continuous flow of 0.21 through 1.0 FI02 adjustable oxygen gas mixture. The mixture is delivered at ambient pressure from one end of the chamber, flows across the animal positioned within the hyperbaric chamber, and exits at the opposite end for exhaust to ambient conditions. A high flow gas mixture is utilized to maintain accurate gas mixture concentrations with fluctuating supply pressures of medical air and medical oxygen gases.

A respiratory and eye protection device having at least one filter and at least one axial fan. The least one filter is configured to achieve an aerosolized particle contamination filtration efficiency of 50% or greater for particles having a size of about 0.3 m and configured to achieve a vapor contamination filtration efficiency of 50% or greater for one or more of Novichok nerve agent (A232), thickened venomous nerve agent (TVX), sulfur mustard agent (HD), thickened sulfur mustard agent (THD), soman nerve agent (GD), and sarin nerve agent (GB). During the operation and monitoring of the respiratory and eye protection device, at least one fan is activated when concentrations of select aerosolized chemical, biological, radiological, and nuclear (CBRN) agents are detected.
