Portable chemical oxygen generator |
摘要 |
A portable apparatus is provided which generates high purity breathable oxygen. The oxygen is produced in a reaction chamber from the reaction between an oxygen generating composition and a water/catalyst solution. The reaction chamber comprises a first compartment containing an oxygen peroxide adduct and a temperature stabilizing material formulated into controlled release tablets and a second sealed compartment containing a catalyst dispersed in an aqueous solution. The temperature stabilizing material undergoes an endothermic reaction upon dissolution in the solution. The tablets dissolve in the solution releasing hydrogen peroxide at a constant rate. The hydrogen peroxide is further decomposed into oxygen and water from contact with the catalyst. A first membrane made from a hydrophobic and gas permeable material, lets oxygen through while containing the reaction materials. A second membrane made of hydrophilic superabsorbent material and impregnated with catalyst particles absorbs any unreacted hydrogen peroxide letting high purity oxygen through.
