Abstract: Due to the damage caused by the deadly coronavirus, and its highly contagious and asymptomatic nature causing increased infections and deaths. Amidst this crisis, the fact of scarcity of ventilators in not just remote places but also in cities has made a prominent impact. The high cost of the mechanical ventilators in the market make sure to keep their prices high during this time of need. These costs in turn make holes in the pockets of the user. Thereby the affordability is only to the financially stable part of the population. The more makeshift of this complex mechanical ventilator is the Ambulatory Bag (AMBU bag). This works when a healthcare worker manually presses the bag to force in air to the patient who has difficulty in breathing. As manual pressing cannot happen for a long duration, a mechanical smart device is attached to this simple medical equipment for automating the process and to connect it to the internet making monitoring and diagnosis easy and also affordable.

This project has 2 main parts:
I) The automation of the simple AMBU Bag.
II) Making this device smart by connecting multiple sensors and connecting them to the internet.
Automation of the simple AMBU bag
The simple AMBU bag is connected to an electrical circuit that is controlled by a microcontroller. The movement of compression of the bag is obtained by wiper motor mechanism. The speed of the motor is controlled by the micro-controller there by having different operation states like Adult, child and Older people. This part of the entire project
automates the AMBU bag.
IoT network
This part of the project deals with the connection of multiple sensors that acquire required parameters that help in monitoring and diagnostics. Multiple sensors are connected together in a network and the acquired data is then displayed to the healthcare worker in-charge of the patient. This enables accurate monitoring of many patient and connects them to their healthcare worker in real time. This task helps the healthcare team to organize their task and also gives them a heads up of the immediate future.

Keywords: Ambulatory Bag, IoT network, wiper motor mechanism, mechanical ventilators.
