WHAT IS OXYNIZER?
Oxynizer is a non-electric oxygen generator system composed of a universal hose system and sustainable filter materials. It can be easily connected to various pumps and delivers oxygen to patients with a range of conditions, from mild breathlessness to chronic respiratory diseases. Its high compatibility, low maintenance, and intuitive operation make the Oxynizer a potential lifesaver for patients in developing countries with limited medical infrastructure.
HOW TO USE
Oxynizer operates through four straightforward steps. The user connects the Oxynizer to any available air supply devices, places the mask on the patient, and pumps to supply oxygen to the patient. To ensure optimal performance, the user opens the top valve in the given sequence to release residuals from the filter, during which time the user can take a brief rest.
HOW IT WORKS
Oxynizer leverages PSA (Pressure Swing Adsorption) technique, standard in commercial oxygen generators. Air pumped into Oxynizer enters a system of universal hoses and one-way check valves, maintaining high pressure. It then passes through silica gel and zeolite loaded in the hoses, undergoing dehydration and nitrogen separation. The resulting oxygen is delivered to the patient through an oxygen mask.
SUSTAINABLE SYSTEM
Oxynizer provides sustainable use with its semi-permanent filter materials that are reused by simple heating. In order to restore the performance of materials, just detach hose from the fitting and pour down the materials into a separate bowl. Silica gel can be regenerated at temperatures between 150°C and 200°C. Zeolite is a semi-permanent material, but, to ensure the best performance it can be regenerated every six months at 200°C.
