Single Adsorber RPSA for Improved O2 Delivery

Project Summary and Abstract The goal of this SBIR Phase I proposal is to build and test a prototype AC powered home Medical Oxygen Concentrator MOC based on a novel patented and patent pending Rapid Pressure Swing Adsorption RPSA technology MOCandapos s are the point of care POC devices used for oxygen rehabilitation therapy for patients suffering from Chronic Obstructive Pulmonary Disease COPD fibrosis and other lung diseases The proprietary single bed compact miniature MOC has a concentric product storage tank and can continuously deliver to Standard Liters Per Minute of O from compressed air The novel RPSA process is capable of lowering the adsorbent weight by a factor of two while offering a better oxygen recovery from air A commercial lithium exchanged zeolite LiLSX selective for nitrogen adsorption will be used as the adsorbent for air separation in the prototype unit A pre treatment layer of alumina desiccant will be added in the feed section of the device to capture the H O and CO from ambient air to prevent contamination of LiLSX adsorbent thereby increasing device life and reliability The operating conditions such as total cycle time individual step durations and operating pressure will be optimized by conducting experiments on the prototype MOC unit A set of operating conditions and procedures will be generated for the best optimum operation of the final MOC device Our long term vision is to incubate this technology to the point of maturity where it is ready for mass manufacture and can be licensed to a manufacturing company This transformative MOC POC design has the potential to address the oxygen therapy needs of nearly of COPD and other lung disease patients in need of a lightweight compact and reliable oxygen supply Project narrative Medical Oxygen Concentrators MOCs are the preferred commercially viable option for the Point of Care POC treatment and rehabilitation of patients with COPD and other lung disorders MOCandapos s can be used in remote locations airplanes cruise ships and military where high purity oxygen is needed A miniature compact robust reliable MOC is needed in the market to improve the lifestyle and comfort level of COPD patients
