20190217132 · 2019-07-18 ·

The invention relates to a portable respirator with potential equilibrium and carbon oxygen exchange which includes a cover, a filtering device and an oxygen supply device. The cover is provided with a sealing ring, an elastomeric headband and a potential balancer. A plurality of fan-shaped filters are stacked in the cavity of the filtering device in a circumferential direction. The oxygen supply device includes a first tank and a second tank. The first tank is provided with a lithium battery, a miniature air pump and a reaction tank. A plurality of radiating copper pipes are circumferentially arranged on the outer wall surface of the first tank. A miniature liquid oxygen tank, an electric pressure reducing valve, a tension spring and an end cap are arranged in the second tank. One end of the miniature liquid oxygen tank is in contact with the end cap by the tension spring. The potential equilibrium and carbon oxygen exchange of the invention has advantages of having reasonable and simple structure, easy to use, small volume, light weight, and portability, etc., which effectively solves the problem of traditional respirators being inconvenient to be carried and used.

Oxygen concentrating self-rescuer device

A self-rescuer device comprises an intake pump that creates a gas stream. The gas stream enters a first sieve that separates carbon dioxide, carbon monoxide, and oxygen from the gas stream to create a mixture. The remaining gas stream flows to a second sieve that separates nitrogen from the remaining gas stream and vents the residual gas to outside of the self-rescuer device through a residual output. The separated mixture is directed to a gas processor separates the oxygen from the mixture. A nitrogen storage canister coupled to the separated output of the second sieve stores the separated nitrogen, and an oxygen storage canister coupled to the separated output of the first sieve stores and concentrates the separated oxygen until a purity threshold is met. Habitable nitrogen and oxygen are metered from their storage canisters and supplied to a user through a breathing mask within an exterior mask shell.
