Due to the current pandemic the number of COVID19, the number of pneumonia has been massively increased, which is by association increased the mortality rate of COVID19 all over the world. In addition, with the limited number of available venatilors in Egypt and all over many of the world’s countries, there has been an urge to increase the number of produced veltaitors all over the world to cover and handle the current situation.

Venta-max ventilators can assure safe and stable breathing in acute pneumonia patients and can directly help in keeping severe COVID-19 patients breathing when their lungs aren’t capable anymore of delivering a sufficient amount of oxygen by itself. Mainly by controlling the pressure of air inside the lungs in both inhaling and exhaling, respiratory rate and the concentration of oxygen delivered.

The ventilator is modular, easy to maintain and clean, and made of widely available materials and sensors with HEPA filtered inlet and outlet. Furthermore, it can be built locally using simple tools and rapid prototyping with simple 3D printed connections. The device can operate using both 110V and 220V with the ability to use internal batteries for more than 180 minutes when not connected to a building AC circuit. A simple, interactive, user-friendly app allows the user/ doctor to control the mechanical and electrical systems using a touch screen to govern the pressure of the air required as well as the exhalation to inhalation ratio. The doctor can control the inspiratory pressure up to 40cmH2O and the expiratory pressure up to 25cm H2O. He can also control the respiratory rate from 5 to 40 breaths per minute and change oxygen concentration according to the patient’s condition. This ventilator is smart and its behavior is easily monitored as the feedback mechanism implemented, along with the sensors used, make sure the pressure and oxygen delivered just before the lungs match those required and alarms the doctor otherwise.

We have faced many issues regarding gathering the required components needed to build our ventilator. Most of the components we bought have not a published datasheet. We struggled operating and calibrating all our needed sensors and actuators. In addition, we have run a very tight timeframe ,as in our country we ran curfew which urged us to do all our logistics in a tight timeframe. Finally, we needed to import some components from outside but for the current situation we should have handled our needed components from other sources used in other types of industries rather than the medical industry sector.

After struggling for some period of time, we managed to run our first complete test of our pressure controlled mandatory ventilation. We tested our device in one of the mega factories in our country on a fluke device. We successfully passed the test with an error percentage less than 0.1%. We learnt many design concepts and system engineering that we were able to change and manipulate our design to fit our available components in the market. For the next period, we are making our industrial version of our ventilator which will be built of higher grade components along with mold made chassis for finalizing the final product and start the long testing phase.
