Oxygen Concentrator Controller with Smart Connectivity

The rise in respiratory conditions such as COPD (Chronic Obstructive Pulmonary Disease) and complications from COVID-19 has led to increased demand for devices like oxygen concentrators, which provide oxygen therapy. These concentrators work by selectively removing nitrogen from a gas supply to deliver oxygen-rich airflow, aiding patient breathing. 

This controller for oxygen concentrators operates in pressure swing mode, where modes 1 and 2 periodically alternate via control valves to absorb nitrogen thereby increasing oxygen concentration and clearing nitrogen through reverse airflow.

System Benefits​:

• Supervision of intake airflow, air quality, temperature, humidity, and pressure ensures consistent quality air delivery.
• The RA Arm^® Cortex^®-M MCU supports the Flexible Software Package (FSP), built on FreeRTOS, and is expandable to other RTOSes and middleware, making it adaptable to various features and requirements.
• Features a user interface via LCD + Touch and/or GUI via Bluetooth^®, connectable to a smartphone for real-time data and flexible control.
• Operates on a standard medical-grade power supply (~24V_DC) for compatibility.
