Respiration Assistive Intervention Device - Respi AID

A ventilator is a mechanical device used to support the ventilation function i.e. breathing function, in patients with weak respiratory systems. Due to the pandemic spread of a novel coronavirus disease 2019 (COVID-19), the requirement of ventilators was envisaged in high numbers. Since the availability of ventilators was not adequate, so an urgent need was felt to develop cost-effective respiration assistance devices with minimum required functionality of ICU ventilator to support the healthcare professionals during the pandemic situations. 

The proposed device is based on the Ambu bag where the operation of the Ambu bag is automated by a motorized mechanism. It has the provision to set the ventilation parameters i.e. Tidal volume, Respiration rate, I:E ratio, PEEP value, FiO2, etc. through the user interface, and the device starts working by applying pressure to the attached Ambu bag. All the parameters are controlled and monitored through the display provided at the front panel. The device can also be used as a transport ventilator.

• Ventilation parameters setting for Respiratory Rate, Tidal Volume, I:E Ratio, PEEP and FiO2
• GUI for monitoring Set values of Tidal volume, Respiration rate & I:E ratio, and Delivered values of Tidal Volume, Inspiration Peak Flow, Inspiration Peak Pressure; Mean Airway Pressure; PEEP
• Oxygen concentration display; Air-Oxygen Blender
• Alarms: Delivered Tidal volume mismatch, Lower and upper pressure limits, Power failure
