US 2025/0018336 A1 · BIO-DEGRADABLE POROUS BONDED-GRAIN MONOLITHIC CO2 SCRUBBER FOR RESPIRATION DEVICES

Abstract

The present disclosure relates to a biodegradable porous bonded-grain monolithic CO2 scrubber for respiration devices. The scrubber comprises a monolithic body of bonded grains, including calcium hydroxide, sodium hydroxide, lithium hydroxide, and potassium hydroxide, to act as CO2 absorbents. The body features enclosed gas passages facilitating gas flow and CO2 absorption. The grains are bonded via adhesion, powder polymer, or heat sintering, and the structure includes hydrophobic additives to reduce caustic solution formation. The scrubber can be manufactured through extrusion or additive manufacturing, with various passage shapes and sizes. The monolithic body may include biodegradable polymers for environmentally sound disposal.
